Aaron Bohy 4f61e7f048 [FIX] web: WidgetDomain: don't crash on false domain
Before this rev., when the value of a field with widget='domain'
was false, the search_count RPC made to display the number of
records matching the domain crashed, and the widget displayed that
the domain was invalid. This rev. adds a fallback on [] when the
domain is false.

Khoi Nguyen 5149e18ec7 [FIX] web: always display handle widget
Before this commit, a list containing a handle widget would only display
the handles associated with non-zero integer values. This is due to the
fact that unset fields are hidden in Odoo, while a field is by default
considered 'defined' if its value is truthy.

We override the isSet method for the handle widget to always return
true. This tells the handle widget that the associated integer value is
always defined, thereby ensuring that the handle will always be shown.

Adrien Dieudonne f5b7ad80fc [FIX] web: always use browser timezone
With the new views, we stopped using the browser timezone to
display the dates in Odoo, and we used the timezone defined on
the User profile instead. When loading the webclient, the
timezone offset was put into the session and used to display all
dates. This wasn't a good idea.

The given offset was computed for the current time, meaning that
it may be incorrect for specific dates (e.g. with the daylight
saving, the UTC offset of today is not the same as 6 months ago).
Moreover (but less likely), as the offset was stored in the
session, it wasn't recalculated afterwards. So if the offset
actually changed during the session (e.g. from or to daylight
saving time), the displayed dates were incorrect until the user
reloaded the page.

With this rev., we don't retrieve the offset from the server
anymore and we use the browser timezone again (like before the new
views). However, we keep the computation of the offset (on the fly)
in the session, so that it can be mocked in the test environment.

Adrien Dieudonne b9bfec96dd [FIX] web: don't apply timezone offset for date fields
Before this rev., all date fields values were off by one day as
soon as the user timezone was negative.

With the new views, all dates manipulated by the JS are moment
instances in UTC, and when being displayed, they are correctly
formatted in the user locale by applying the timezone offset.
However, this should obviously not be done for date fields as
when no time is specified when creating a moment instance, it
defaults to 00:00:00, so applying a negative offset always leads
to the day before.

Remark:
It happens that datetime fields are displayed as a date (e.g.
purchase order line form view). In that case, the offset is
applied on the displayed date.

Khoi Nguyen 178873d433 [FIX] web: fix copy (Ctrl-C) of text field content in Firefox
Before this commit, it was not possible to copy the contents of a
multiline text field in read-only mode in Firefox without losing all
line breaks in the process. This is due to a bug affecting div tags
(see https://bugzilla.mozilla.org/show_bug.cgi?id=1390115) in Firefox.

This commit ensures that the text in a text field is surrounded by a
span (as opposed to div) tag.

Note that spans were used in saas-15, so we are in fact simply undoing
the change to divs introduced by the new views.

Adrien Dieudonne a71f223702 [FIX] web: InputField: don't re-render if dirty
Let's assume that we have a form view with a one2many field
displayed as a list containing two fields A and B (an input field,
e.g. a char field). An onchange on the one2many is triggered as
soon as A changes. This triggers a reset of the one2many which
thus redraws the corresponding line by resetting its widgets.

A problem occured when the user updated A, and directly (before
the onchange returned) updated the input field B, as in this case
the new value in B was erased when the onchanged returned, as the
widget was reset with its former value (or with the value returned
by the onchange, if any). Note that the model was aware of the
change on B, so the model and the UI were actually desynchronized.

This was quite hard to reproduce in practice, by hand, but it
occured in the tour testing 'the flow', in the form view of
account.bank_statement, with fields partner_id and amount of the
line_ids one2many.

With this rev., we don't re-render the input fields if there are
pending changes that haven't been acknowledged by the model.

Ankit Sathvara f41bd82f66 [ADD] web: Add new widget to toogle a boolean with a slider
Purpose
=======

Currently, it's not possible to activate a boolean on a non-editable list view without adding 2 buttons linked to a python method. These buttons aren't aligned and the result is not pretty.

This commit adds a new widget that allows to toggle a boolean record by record by clicking on the slider.

Géry Debongnie 514c8e5cd3 [FIX] web: prevent dirty state after test
The test changed in this commit had a big issue: it did not properly
destroy the second form view that it created.  Because of that, it was
still alive and could interact with other tests, such as the barcode
tests.

This is what happened:
1. var form was assigned to a form view
2. form was destroyed
3. in a try catch, form was reassigned to the result of createView, but
the evaluation of createView crashed (after creating a form view), so the
assignation was not done, and the var form was still pointing to the first
form view
4. form.destroy is called, which did nothing for the second form view.

There is no easy way to get the reference to the form view created by
createView without changing some other code, so we simply remove the
second part of the test, which was not particularly important.

This should not be the case for a textarea (i.e. in the FieldText widget). In
this particular case, we just want to continue editing the textarea.

Aaron Bohy 7ea6f653df [FIX] web: MonetaryField: rerender with currency
The MonetaryField can be rendered with or without a currency. The
currency can change during the lifecyle of the widget (e.g.
currency field in the view, whose value is set by an onchange).
More precisely, the widget can be instantiated without currency,
then a change on another field can trigger an onchange which sets
the currency, and our monetary widget is re-rendered with a
currency.

Before this rev., this wasn't supported in edit mode because the
$el's root node was different if there were a currency or not
(it was an input if there were no currency, and a div containing
an input and a span otherwise). This root node being rendered only
once (at the creation of the widget), the widget wasn't re-rendered
correctly if the currency was suddenly set or unset.

This fix makes the widget behave uniformly whether or not there is
a currency, so now it is always a div containing an input (and
optionally a span if there is a currency).

returns 0 for unset numeric fields.

Aaron Bohy 8859d25bc5 [FIX] web: FieldWidgets: use correct format/parse functions

be formatted with the float formatter, not the montetary one. This
wasn't the case before this rev.

Aaron Bohy c929a81e8f [FIX] web: DebounceField: do nothing after widget destruction
DebounceFields debounce the function that notify field changes to
their environment (using _.debounce). It may happen that this
function is called once the field widget is destroyed (e.g.
type something in a char field and quickly click on Save, the
function is called directly by _commitChanges, but the debounced
call is still pending). It may be a problem if the subsequent
code does something like this.getSession().some_key, as if the
widget is destroyed, it has no parent that can provide it the
session, and thus it crashes.

Also rename attribute _debouncedStarted into _isDirty as it makes
much more sense.

Aaron Bohy ba6a3a91ae [FIX] web: MonetaryField: read currency_field in options
In the xml definition of views, a 'currency_field' can be specified
in the node options:

<field name="amount" widget='monetary'
       options="{'currency_field': 'currency_id'}"/>

It indicates which field the monetary widget has to use to
determine the currency to display.

Before this rev., the widget didn't look for the 'currency_field'
in the options, but directly in the node attrs, so this simply
didn't work. This was for example the case on the crm.lead kanban
and form views.

Géry Debongnie c8d77f93e5 [FIX] web: display empty input fields properly
Before this commit, it was not possible to see the difference between an

value 0)

This was due to the fact that the formatFloat/formatMonetary functions
format false values as the number 0, unlike many other formatting
functions.

Aaron Bohy c04b840a45 [FIX] web: FieldMonetary: don't loose focus after edition
... in x2many editable list views.

Field widgets can detect that they are at the origin of a
field_changed event, so that they don't re-render themselves when
they are being edited.

This didn't work for fields inside x2many list views. This wasn't
a big problem for most of the fields, because the cursor position
was automatically reset after a re-rendering, but it wasn't
working for monetary fields that empty their $el before each
re-rendering.

This rev. fixes the issue by making the field widgets inside
x2many list able to detect that they are the origin of a change,
and thus removes the now useless code that restore the cursor
position.

Géry Debongnie c75680c527 [REF] web: optimize basic model (improve perfs for most views)
The 'get' method in the basic model is called very often (too often, but
that is another issue).  For a large list with many columns, it can be
quickly be called more than 10k times.

In that function, we had to protect our integrity by performing a deep
clone with $.extend, so noone else can be allowed to change something in
our internal structure.  This is good in theory, but not so good in
practice, as $.extend is a really expensive operation.

Also, we try to have the smallest external API by deleting useless keys.
But instead of keeping a blacklist of private keys, it is simpler to
have a whitelist of public keys.

So, what we do is to explicitely construct the object returned by key,
since we know the types of every values involved.  This is more
explicit, and at the same time, much faster.

Also, we propagate the options for elements of type list.  This is why I
had to change the isFieldSet method.

In a benchmark I just ran, loading and rendering a large list (200 rows,
7 columns) went from about 2.7s to 0.7s.

We still do way too much work, but at least it is much faster...

Aaron Bohy e8f9bb683d [FIX] web: DebouncedField: notify changes only when changed
Before this rev., if you opened a form view with, e.g. a float
field, that is unset, and then click on edit, then save, it
actually saved the new value for the float field (being 0),
whereas it shouldn't do any RPC as nothing changed.

This is because the former code couldn't detect if the value "0"
in the input is there because the field is still unset or if the
user simply set it to 0.

qsm-odoo 250e716c3a [REF] web, *: restore views design
Since the new views merge, a lot of design elements were broken. This
was particularly impacting the fields in the editable list view; indeed
the editable list view is not using an inline form view anymore so the
fields in the list were not properly styled as the LESS was still
defined assuming the form view environment (for example the invalid
fields were red for o2m fields in form view but not in editable list
view even though they got the right CSS class).

This commit refactor the LESS following these rules:
- No more division of non-layout and layout rules. Dividing LESS rules
  in x_layout.less and x.less was a mistake. Many rules can be
  considered to be layout and not layout at the same time, developers
  always have to switch from one file part to the other, many CSS
  selectors (and rules!) are duplicated for nothing, ...
- Field style is extracted from x_view.less and put in the new
  fields.less file. As before, the fields_extra.less will contain the
  rules specific to community so that the enterprise repo can override
  those by replacing the whole file.
- Many classes have been renamed so that o_form_x_y becomes o_x_y as
  many classes can now be applied outside of form view. These classes
  should not be used in templates anyway.

The commit also changes the DOM of fields so that it is more minimalist
(no useless parent div, etc).

Input elements are not automatically styled anymore, they have to get
the o_input class explicitely. This allows to fix lots of small style
bugs of previous versions (required monetary field had not the proper
style, readonly m2m tags appeared as editable, ...). This also improves
the LESS code.

The editable list view should also completely stop flickering on chrome
and firefox.

The commit also removes the orange outline on list view dirty cells.

The commit also removes deprecated static xml, LESS and other code.

Notice there are still styles to restore/fix and LESS to improve.

qsm-odoo 03c4c855b9 [REF] web: restore editable list views behaviors
Since the new views, the editable list view lost some behaviors. These
behaviors were indeed implemented in the form controller/renderer but
as the new editable list view does not use an inline form view, these
behaviors had to be implemented in the basic controller/renderer.
For this to work, the list editable renderer had to be changed as it
was doing work that should be done by the controller.

The problem is even more complex because the x2m fields are using a
list renderer but not a list controller. So moving code from the
renderer to the controller obviously broke the x2m fields. Right now,
the problem is solved by catching renderer events and forwarding new
ones to the form controller (which handles the x2m specifically).

The initial goal of this commit was to share the validation of records
on save. Indeed, the fields were marked as invalid in the form view but
not in the list view. Also, before the new views, the editable list
view had different behaviors if they were used for a x2m field or not.
As these behaviors are making sense, this commit tries to restore them.

Basically, what we want is:
- When a record is saved (form view save or list view line leaving),
the invalid fields are marked (in red), the names of the related fields
are notified to the user and the record is not left.
- When a record is discarded (form view discard or list view discard),
the user is asked to confirm if the record is dirty before making the
record readonly.
- When a record is discarded, if the record is a new one, then the
record should be abandoned (removed as if never existed). In the form
view this induces to go back in the history and in the list view, to
remove a row.
- For x2m fields, the notification of invalid fields is not triggered
but the user is instead asked if he wants to discard the changes made
to the row (indeed, this replaces the list "Discard" button, as non
existent for x2m lists).
- ...

Saving, discarding, marking the fields as invalid and other behaviors
are thus now shared behavior of basic views.

The management of the dirty flag has also been moved to the model
as it was handle by the controller for the form view but by the
renderer for the list view. Now this flag is directly managed in the
basic model (the model can have changes thanks to the `_changes`
property but not be dirty (this is the case for creations)).
This change however created a problem. The view manager is currently
keeping asking if there are changes to discard at each action which
might lead to leave a dirty record (appswitcher / url change / ...).
It however did not discard anything as leaving if the user is ok with
it will lead to an implicit discard. However, as the view manager might
ask for this discard multiple times by second, the controller was
marking the record as not dirty the first time but without discarding
the changes. This is more complex to do now, as the dirty state is
part of the model and that the renderer should match the model data.
To solve this problem, the view manager now actually discard changes
explicitely when asked to. Even though this had been optimized to not
cause any rerender in some cases where it is not needed, this could
cause some performance decreasing. However, this makes some cases more
logical (opening the app switcher on a dirty form view then going back
to the form view by hitting the "go back" button left the form view
untouched although the user asked to discard it). This solution will
be improved with the view manager refactoring.

This commit is also making use of the `commitChanges` system which had
been implemented for HTML fields. Indeed, these fields cannot know
about all of their changes, so when hitting the save button, we asked
those fields to commit their value. Using this system is a great way
to make the `isValid` method of x2m fields synchronous. Indeed, before
this commit, the method was sometimes asking the user if he wants to
discard an invalid line before save. That case can be handled by the
x2m `commitChanges` method: we consider that saving the lines of x2m is
an operation that has to be done before considering the save, so we ask
all the x2m fields to do so at that time. Also, the system was broken
since a recent commit: we indeed protected the changes - save order
with a mutex but unfortunately, the `commitChanges` method was part of
the save and the changes it triggered were not able to be considered
because of this mutex. This had not been detected by tests as there is
not current way to test html fields.

Géry Debongnie 54a90ca919 [FIX] hr_holidays,web: proper use of toggle_boolean in list view
hr_holiday was the only module that used a widget=toggle_boolean on a
button in a list view.  That behaviour was implemented as a column
widget in the previous list view, and was not reimplemented in the new
views. The feature is useful, but this was not done properly: it is
better to use a widget on a field (that was the intent) instead of doing
a weird hack like it was done.

With this commit, we update hr_holidays to use the ToggleBoolean widget,
which is supposed to work on every views.

Also, we fix the toggleboolean widget (it was not properly rendering
tooltips, and changes were not saved in readonly list view).

Note that it as the side effect of being better from the point of rpcs:
before, the list view had to reload itself.  Also, another advantage is
that models do not need to implement custom methods (such as
toggle_payslip_status) just to toggle a boolean...

rendering.

The previous solution to clean up only deleted ace and require

a potential second test using ace (because the scripts were still

work either because the loadJS function uses an internal cache

of "python field" instead of "view field", ...). This commit tries to
implement a system which allows to handle the modifiers (re)computation
the same way for all the basic views.

For this to work, many specialized renderers behaviors have been moved
to the basic renderer so that more mechanisms are shared (especially by
the form renderer and the list editable renderer). The list editable
renderer is hugely impacted by this commit.

Here is a list of key changes:

- The basic renderer now has a `_renderFieldWidget` function which is
  used without modification by the form and the list renderers.

- Modifiers have to be registered thanks to the basic renderer
  `_registerModifiersData` function (this is done automatically for
  fields by the `_renderFieldWidget` function for example).

- All instantiated widgets are accessible, organized by record, and
  ordered in a special basic renderer variable.

- The code which resets the widgets of the form view and the code
  which updates the row of a list editable view is now shared in the
  basic renderer and now also automatically updates the DOM according
  to the reevaluated modifiers.

- The last point has an huge impact on list editable renderer: all the
  widgets have to be instantiated when editing a row (even readonly and
  invisible ones) as they can be switched to editable/visible during
  edition (after a modifiers update).

- `replace_element` and `readonly` options of `AbstractField` are
  useless: widgets are now always replacing the list editable cells
  in edition and the `readonly` widget mechanism is replaced by the
  notion of 'focusable' widgets.
  (see `AbstractField.getFocusableElement`)

- The 'tab' navigation mechanism is impacted by the previous point,
  some code sharing have been done in basic renderer for this too.

- `AbstractField` does not care anymore of the 'required' status, this
  is the view responsability to check that a required field has a set
  value on save.

- Some list editable bug fixing (e.g. it was possible to edit multiple
  rows at the same time, it was not possible to navigate towards the
  previous field, crash on o2m add an item click, ...)

- The mockserver now properly simulates server modifiers computation.

- ...

Note: list editable style may be worse than before this commit but a
CSS update is coming in a few days.

Pierre Masereel 2b22ceea6f [FIX] web: date_picker empty input field
When you try to empty a date or datetime field, you get a traceback
saying that 'clone' and 'isSame' are not functions.

This error occurs when you empty the field because the value is 'false'
and you cannot call 'clone' or 'isSame' on false.

To fix this, we ensure that value is not false before calling these
methods on it.

This bug has been introduced in rev: https://github.com/odoo/odoo/commit/c32724eae06c987e74a0600f1669696e499edc33
