In f65475d6 one2many fields of default view in a form view were propagated
to the ORM so the value received from an onchange was not empty.
These new steps test this on a tree view embedded in a form view, or a
tree view originating from a default view by testing onchange adding row
or updating values of a one2many.
In a form view, when a field onchange lead to a change on a x2many,
there was two different behavior:
- if the x2many had an embedded view (eg. a tree view inside a form
view) the onchange would notify that it expected the x2many field in
this embedded view to be changed and handled the changes correctly.
- if the x2many had a default view, the onchange ORM would not be
aware the x2many could be modified and would not sent the changes
back causing blank or not updated x2m lines and error on save.
---
Two solutions were birthed to solve the second point:
=> PR #10557 = solving everything
With this PR the onchange in the ORM is aware of every fields in the
current view (even field in a x2m in a x2m in a x2m in a form view) and
if any of these are change the javascript gets back the value of the
fields present in the view.
This PR has currently not been merged by fear of changing too much and
anyway could only be done in master.
=> PR #12249 = if no field for x2many, send its form view fields
With this change, if the ORM onchange is not aware of the fields in the
x2many widget to returns, all the field in the x2m default form view are
returned.
This was merged in bbdf960 but introduced a number of other issue:
- in most situation the x2many is represented by a list view, which may
have fields missing of the form view, so the original is still present.
- the view used may differ from the default form view in other way
(depending on value in context or other possibilities).
- the form view could have fields not present in the form view which
could end up in `write` on fields which should not be written to.
---
This commit reverts bbdf960 and adapts a small part of #10557 so the
x2many with default view works as an embedded x2many. For more than one
level (eg. a x2many in a x2many) this would still not work but it is
only solvable by a PR such as #10557 which could only be targetted for
master.
With this commit:
- the list of fields sent to ORM onchange is computed at the first onchange
- the fields from a x2many field default view is sent for onchange
- the initial onchange on record creation is delayed to when x2many are loaded

We sometimes use in Odoo a One2many field with an inverse Integer
field instead of a usual Many2one.
This allow for example in several instances to have a "Many2one" which
can be reference from several models, eg:
Model Ranking:
name = String field
res_id = Integer field
res_model = String field
Model Toy:
rank = One2many [inverse: Ranking -> res_id]
[domain: res_model == Toy]
Model Tool:
rank = One2many [inverse: Ranking -> res_id]
[domain: res_model == Tool]
This enable us to have a shared feature between otherwise unrelated models.
But there was several issue when searching on these One2many:
1) if the Integer Many2one was not stored (eg. it came from an inherits) on
the searched model, this could lead to an error.
2) when we searched:
- by IDs (rank in ['55']) with at least one id not respecting the domain
- by IDs with a negative operator
- with a negative operator on unfound string (rank != "no rank has this")
- with a false value (rank = False)
we would not apply the One2many domain (eg. res_model == Toy) and thus
possibly getting Toy 3 errenously because a Tool 3 was found without
the domain being applied.
This fix modify the search on One2many and for:
1. if the inverse is an Integer not stored field instead of Many2one
manage it.
2. if the field is an Integer field instead of Many2one and there is a
domain on the One2many: apply the domain on the inverse model found.
So only some search on One2many with a domain whose inverse field is an
Integer could be impacted.
This would also be nice to have for all One2many with a domain but the
probability of it being useful versus risk for performance is not judged
high enough.

This removal has led to a necessary refactoring:
- make the setup of field attributes extensible;
- make the instantiation of custom fields extensible;
- delegate model and field reflection to `ir.model` and `ir.model.fields`;
- move the implementation of sparse and serialized fields to module `base_sparse_field`;
Remove unrestricted "read" access. To make code internally using `ir.model`
work, add a private method `_get` on `ir.model` to retrieve the record
corresponding to a model name, without access rights issue.
Change signature of method `get_authorized_fields` to make it use a model name
instead of a model id. This removes the necessity of a search on `ir.model`.
