As `manual` is now the default value of the `state`,
if `state` is not given in the values when passed to
`create` or `write` of `ir.model` and `ir.model.fields`,
we must assume the value is `manual`, so the columns and tables
are instanciated in database

This was possible to create custom fields `x_*`
but seen as base fields.
For instance,
- Go to Settings > Technical > Database Structure > Fields
- Select a field (any)
- Click on the model link, to be redirected to the model form
- Edit & add a custom field from there.
- Save
- Notice that the field you just added is saved as a base field.
We solve this issue by assuming that all created fields and models
are customs, except the ones created by the ORM, by the database
initialization, the fields coming from the modules in python.
We therefore remove the mechanism on which a field was set
as custom according to the fact `manual` was set to True within
the context: This is now the case by default.
No change was required for the base fields: The `state` `base`
was already forced for those fields, that are created using
direct SQL requests `INSERT INTO`.

Avoid "patching" the registry, as this introduces inconsistencies (some field
attributes are lost). Instead, proceed as follows:
- update the definition of custom fields in database;
- clear the corresponding cache on the registry (this was missing);
- setup the models in registry (this reloads the custom models and fields);
- update the database schema of the models based on the registry.
This makes the update of custom fields simpler and more robust.
When importing a CSV file with an "id" column containing
external IDs (XML IDs), the system automatically creates
or updates the corresponding ir.model.data entries.
This would fail for regular users who do not have
create/write access on this internal model.
The implementation of `ormcache` does not work on methods that take a `context`
parameter. Because of the decorator `decorator`, the arguments of the call are
passed positionally to the method `ormcache.lookup`, and positional arguments
are used in the cache key.
The fix consists in removing the `context` parameter from the faulty methods,
either directly, or by caching a private method called by the public method.
When a `noupdate` record is processed during an update,
the update_dummy method marks the record as "seen" so
it won't be deleted at the garbage collection step,
and seen as an obsolete external ID.
This needs to be done also for the parent records via
_inherits, because they have also received an implicit
external ID at creation, and must not be garbage
collected, even if their `noupdate` flag (db side)
is not set because the flag was added later.
This rare problem could be reproduced by creating a product
in a module, then referencing it in e.g. a sales order,
then updating the module after changing the product
record to be in a `noupdate` block.
At the end of the update the implicit product.template
record would be garbage collected, and trigger a cascade
deletion of its children - blocked by the SO reference
to the product.
The invalidation in registry was done only if the field's model was already in
registry. This situation is not the case when you create a custom model with a
custom field.
When a stale XML ID exists in the database, `_update_dummy()`
must consider it as missing entirely, and the next call
to `_update()` will take care of cleaning up the old XML ID.
Failing to do so for `noupdate` records means the `_update`
will never happen, and as soon as another record is created
or updated with a relationship to that stale XML ID, it will
plainly crash the installation/update.
Loading views for custom models from module data files was not possible because
custom models and fields were introduced into the registry after all modules
were loaded. As a consequence, the view architecture did not pass the checks.
This patch takes a different approach: custom models and fields are loaded
early on in the registry, so that views can be validated. The trick is to take
special care of relational custom fields: we skip them if their comodel does
not appear in the registry. This allows to install and upgrade modules that
create/modify custom models, fields and views for them.
During a migration of database, it is possible that some custom field
("x_", state is 'manual') are relational to model from a module that is
not provided.
Note: this used to work in Odoo 7.0 but crashed in 8.0.
Closes#3877
Creating custom fields would crash on a model that has a related field without
string. The crash was caused by the field not being set up, and method
BaseModel._field_create() violating a non-null constraint on the field string.
This has been fixed by setting up fields before updating ir_model_fields.
Deleting a custom field could also cause trouble when that field is inherited
in a child model. In that case, the registry was simply no longer consistent.
The fix is to reload completely the registry.
The modification of custom fields was not reflected on field objects. The fix
applies changes on fields before updating columns accordingly.
This field is needed to retrieve the list of inherited fields (instead of only the fields of a current model) of a model using domain such as ('model_id', 'in', model.inherited_model_ids) on ir.model.fields
When a new ir.model.field is created, add the new field in the fields_by_model (cache of custom fields). This is required as the __init__ method would not retrieve the new field if fields_by_model is already set.
Otherwise, the _columns would not contain the new fields and we could not access it without restarting the server (e.g. the installation of a module adds ir.model.fields and use it in the a view.
Comparing an id and a browse record will always fail so the exception would have always been raised when changing a model (e.g. updating a module with custom fields).
- display_name uses name_get and not the other way around:
name_get should not call _compute_display_name, _compute_display_name should call name_get.
The previous behaviour was not backward-compatible with the old api.
All the models redefining name_get would have 2 different behaviors between name_get and display_name.
- Do not set an inverse function to display_name:
In most cases, writing on display_name writes on _rec_name (if any, not mandatory).
If the display_name computation is redefined, we need to redefine as well the inverse method to avoid unexpected behaviour
This required to also modify tests in base_import as readonly fields are avoided.
- Remove search method on display_name:
For the same reason as for the first point, it could be good that searching on display_name use name_search (and not the other way around).
However doing this would be very inefficiant (need to do the search, without limit, extract the ids of the name_get result just to generate
a subdomain ('id', 'in', [...]). As in most cases it would anyway mean to search on the _rec_name it's better to directly do so.
- Changing label to avoid mismatch:
In view displaying the list of fields or when a match is made on the label of a field (e.g. when importing csv file,
matching is made on both label and technical name), the fact that display_name field has '
Calling it 'Display Name' will avoid most errors.
- remove display_name definition from website_forum_doc,ir_model:
These fields are doing the same thing as the display_name of the new api, we can remove them.
We need to keep the one for res.partner as it's a stored field.
orm: do not try to create ir.model.relation for custom m2m as self._module is either empty (for custom models), either the one of the last inheriting module (which is wrong). The field should be removed manually and should not be impacted by the uninstallation of modules. The removal of the relation table can be done when removing manually the custom field (see rev 6af3193).
ir.model: when removing a model, drop the table with the CASCADE instruction. This will remove left constraints from remaining m2m tables.
This means that dropping a table (either manually removing a custom model or uninstalling a module) will not drop the relation table for a custom m2m field. This is not ideal but better than the previous behaviour (which was to fail the DROP TABLE instruction and keep the table with a few columns and unconsistent data).
When droping a column, remove also the relation table in case of custom m2m field.
The relation table needs to be dropped otherwise an unremovable constraint to the targetted table is kept (and anyway is not needed anymore).
A squashed merge is required as the conversion of the apiculture branch from
bzr to git was not correctly done. The git history contains irrelevant blobs
and commits. This branch brings a lot of changes and fixes, too many to list
exhaustively.
- New orm api, objects are now used instead of ids
- Environements to encapsulates cr uid context while maintaining backward compatibility
- Field compute attribute is a new object oriented way to define function fields
- Shared browse record cache
- New onchange protocol
- Optional copy flag on fields
- Documentation update
- Dead code cleanup
- Lots of fixes
When uninstalling a module, remove the ir.model.constraint after removing the non-model records and before fields and model definition.
Without this fix, some constraint would be removed too early allowing to have broken relations and data left from removed module.
On uninstalling, if external ids are associated to an unexisting field, we do not try to delete the field (as it doesnt exist) and we remove the orphan external ids
