The double inversion introduced by 6e063188 is done to catch default 0
values.
For example '>= -3' is transformed in "NOT what is found by < -3".
There was an issue with '> 0' and '< 0' since in these instance 0 don't
match and the inversion must not be done.

* Failing test for one2many [(5,)] action, when domain is callable.
The problem is that `self` inside a callable domain becomes the comodel when at [(5,)].
* [FIX][fields] Make [(5,)] with computed domain work.
To reproduce this failure, declare a field like:
```
child_ids = fields.One2many(
comodel_name="other.model",
domain=lambda self: [("id", "in", self._ids_to_find())],
)
```
Now set some value to it.
Now unset them. Impossible because ``self`` becomes ``other.model`` in domain evaluation.
When uninstalling a module, the model *may* be removed from the registry
before the removal of the model constraints; to prevent crashing in
those cases, a simple replace('.','_') on the model name should allow to
obtain the table name in these cases.
Backported to 8.0 following report at #12648
[FIX] base: use datetime instead of date
The variable `date` is compared to the field `name` in the selection
query. `name` is filled in with datetime data. In particular, in the
module currency_rate_live, datetime.now() is used in the name. It is
necessary to make an appropriate comparison to make sure we select the
updated rate right away.
Fixes#12648
Consider fields G1 and G2 being computed fields with inverse methods that
require the value of a common dependency F, which is also a computed field.
For inversing G1 and G2, their values are put in cache, then their inverse
method is called. If the inverse method of G1 requires the computation of F,
setting F's value will invalidate both G1 and G2 in cache. Hence the value of
G2 is lost when invoking its inverse method!
The fix consists in marking G1 and G2 as being computed before invoking their
inverse method, which prevents them from being invalidated by field F.
Our usage of domain on fields One2many seems to trigger an obscure behaviour on
onchange.
With the following (simplified) config:
Message(models.Model):
_name = 'test_new_api.message'
important = fields.Boolean('Important')
Discussion(models.Model):
_name = 'test_new_api.discussion'
name = fields.Char('Name')
important_emails = fields.One2Many('test_new_api.emailmessage', 'discussion',
domain=[('important', '=', True)])
Email(models.Model):
_name = 'test_new_api.emailmessage'
_inherits = {'test_new_api.message': 'message'}
discussion = fields.Many2one('test_new_api.discussion', 'Discussion')
message = fields.Many2one('test_new_api.message', 'Message')
Steps:
- We change 'name' on discussion, triggers an `onchange()` call
- we ends up filling cache on virtual record (on secondary fields, we calling
record.mapped('important_emails.important'))
- we get a cache miss ('important' field not provided, only 'important_emails' ids,
i.e with no change on existing records)
- we fill the cache, this mark 'important' field as modified
- because of commit 5676d81 and because 'important' is that case is a related (i.e
computed) field we triggers cache recomputation
- as there is no way to recompute 'important_emails' for virtual record (no real
ID) we ends up with empty 'important_emails' generating removal of existing records.
=> Finally changing any value for 'test_new_api.discussion' that trigger an onchange
will always reset 'important_emails' to empty
Fixed by Raphael Collet <rco@odoo.com>, and test by Xavier Alt <xal@odoo.com>.
This reverts commit d780f9476d.
Did not work due to the size=3 on name field that strips the code to the first
three letters only (removing the " (copy)" part).
Copying a currency has a few business cases as the rates are not copied.
As can not increase the size of a field in stable, remove the method that had no
effect.
