- simplify initialization of form._values (don't fill in with False) - use UpdateDict for form._values (more consistent with x2many values) - better/simpler API for getting save/onchange/all values - don't reparse subview in O2MForm (already done by toplevel Form) - guarantee that one2many fields always have an edition view - add assignment on many2many fields - add __getitem__/__setitem__ to access/assign fields with dynamic name Part-of: odoo/odoo#127400

""" Server-side form view implementation (partial)
|
|
|
|
Implements much of the "form view" manipulation flow, such that server-side
|
|
tests can more properly reflect the behaviour which would be observed when
|
|
manipulating the interface:
|
|
|
|
* call the relevant onchanges on "creation";
|
|
* call the relevant onchanges on setting fields;
|
|
* properly handle defaults & onchanges around x2many fields.
|
|
|
|
Saving the form returns the current record (which means the created record
|
|
if in creation mode). It can also be accessed as ``form.record``, but only
|
|
when the form has no pending changes.
|
|
|
|
Regular fields can just be assigned directly to the form. In the case
|
|
of :class:`~odoo.fields.Many2one` fields, one can assign a recordset::
|
|
|
|
# empty recordset => creation mode
|
|
f = Form(self.env['sale.order'])
|
|
f.partner_id = a_partner
|
|
so = f.save()
|
|
|
|
One can also use the form as a context manager to create or edit a record.
|
|
The changes are automatically saved at the end of the scope::
|
|
|
|
with Form(self.env['sale.order']) as f1:
|
|
f1.partner_id = a_partner
|
|
# f1 is saved here
|
|
|
|
# retrieve the created record
|
|
so = f1.record
|
|
|
|
# call Form on record => edition mode
|
|
with Form(so) as f2:
|
|
f2.payment_term_id = env.ref('account.account_payment_term_15days')
|
|
# f2 is saved here
|
|
|
|
For :class:`~odoo.fields.Many2many` fields, the field itself is a
|
|
:class:`~odoo.tests.common.M2MProxy` and can be altered by adding or
|
|
removing records::
|
|
|
|
with Form(user) as u:
|
|
u.groups_id.add(env.ref('account.group_account_manager'))
|
|
u.groups_id.remove(id=env.ref('base.group_portal').id)
|
|
|
|
Finally :class:`~odoo.fields.One2many` are reified as :class:`~O2MProxy`.
|
|
|
|
Because the :class:`~odoo.fields.One2many` only exists through its parent,
|
|
it is manipulated more directly by creating "sub-forms" with
|
|
the :meth:`~O2MProxy.new` and :meth:`~O2MProxy.edit` methods. These would
|
|
normally be used as context managers since they get saved in the parent
|
|
record::
|
|
|
|
with Form(so) as f3:
|
|
f.partner_id = a_partner
|
|
# add support
|
|
with f3.order_line.new() as line:
|
|
line.product_id = env.ref('product.product_product_2')
|
|
# add a computer
|
|
with f3.order_line.new() as line:
|
|
line.product_id = env.ref('product.product_product_3')
|
|
# we actually want 5 computers
|
|
with f3.order_line.edit(1) as line:
|
|
line.product_uom_qty = 5
|
|
# remove support
|
|
f3.order_line.remove(index=0)
|
|
# SO is saved here
|
|
|
|
:param record: empty or singleton recordset. An empty recordset will put
|
|
the view in "creation" mode from default values, while a
|
|
singleton will put it in "edit" mode and only load the
|

view's data.
