Otherwise if a record rule is defined on a x2many field on the model, the creation will fail because
ir.translation creation check access rules on the model and in this case, the x2many relation are
not set yet.
The command does not need to remove existing relations, as there is no relation
yet on new records. This saves one query per many2many field with that command
in a `create`.
Make `RecordCache` work on a single record only, and implement a mapping from
field names (only) to values.
Also add explicit methods on `RecordCache` to wrap special behavior in cache,
and simplify all special values as a wrapper for a getter function.
The record cache may contain regular and special values. Modify `RecordCache`
so that only methods ending with `_value` check for regular values. The
dictionary methods considers both regular and special values as equivalent.
name in record._cache # test if cache has a value
iter(record._cache) # iterate on values
record._cache[name] # get value
record._cache.get(name) # get value or default
record._cache.has_value(name) # test if cache has a regular value
record._cache.get_value(name) # get regular value or default
The x2many "create" command is now like: `(0, ref, vals)`, where `ref` is an
arbitrary reference that may be used to identify a new line in the relation.
The reference is returned in a similar command by the method `onchange`.
`onchange` now supports self-modifying x2many fields.
The behavior is no longer implemented by the web client. Implement it
server-side as part of the onchange mechanism, simply by defining onchange
methods for the fields that have the flag.
Now that we're closer to switching to P3 for good, these helpers have
outlived their usefulness, and mostly add noise.
All remaining dict.iter*() or dict.view*() must be converted to the
normal keys(), values() or items() calls.
Whenever the result is likely to be used for more than the scope of a
loop, or when the dict needs to be modified during iteration, the calls
must be wrapped in a ``list()``, to protect the new P3 semantics.
Those cases are very exceptional.
Also removed some dead code or improved the API to remove unnecessary
conversions.
* remove references to basestring & unicode (use relevant pycompat
helpers)
* remove some str calls (either entirely or replaced by relevant
helper, either text or native)
* use better API to avoid unnecessary conversions
* remove some XML declarations in views
In case of foreign language, using unicode characters, the error message may be
badly formated.
e.g.
Unknown error during import: <class 'odoo.exceptions.AccessError'>: เฉพาะผู้ดูแลร..

When deciding to prefetch records (getting records from the cache with
no value for the field being fetched), if the field was computed
`determine_value` would just get all records, not limited by the normal
prefetch limit; for large recordsets this would generate gigantic
prefetch lists for records we may not need at all.
Fix by applying the `PREFETCH_MAX` limit to records from the cache as is
done in `_prefetch_field`.
Complementarily, when traversing related fields the prefetch
environment would be lost and every record would get an empty prefetch
environment, so the values would ultimately be read one by one.
Example: select (search) 1000 product.product records, access a
related field (e.g. categ_id) in a loop, on the first iteration the
system would first read 1000 templates, then it would read each
categ_id individually, resulting in >1000 SQL queries rather than the
~2 we would expect.
Fixes#18511
When several fields are modified and trigger the same recomputations, the same
SQL queries were made to determine the records to recompute, because each field
was processed independently. In order to avoid duplicated SQL queries, process
the triggers of the modified fields altogether.
This reduces the number of queries by 15% to 25%, depending on the number of
computed fields.
In order to be able to identify what action to return based on the
access_user.
Typically portal users will need to be redirected to the front-end,
while internal users will need to be redirected to the back-end.
When a model contains a field translatable which has a unique
constrain, it is impossible to copy a record. Indeed, the unicity
constrain is always triggered, even if the model takes in charge the
overriding of the copy method to avoid duplication.
Introduced with commit ce7f31b0b0, with the goal to target only
XML/HTML translations. We apply this behavior in case of a callable
translate property, to target only the desired problematic use case.

In P3, random.sample requires that its parameter be a Sequence or a
Set. This blows up _cart_accessories.
So opt BaseModel into both ABC, seems to work fine.
