The method was expecting that name_get() returns complete and in-order values.
Because of this, some records in the recordset could end up without a value.
The method onchange() executes onchange methods in cascade. Suppose onchange()
is called and a field F=1 in the form. If an onchange method set F=2, that
value is put in the result variable. If another onchange method set it back to
F=1, the binding F=2 must be removed from the result variable.
Fixes#2309
Cascading onchanges can be caused by a related field computed in cache. This
causes a bug in sale order lines, were setting the uom field forces reading
product fields, which are inherited from product templates. The inherited
fields are computed as related fields, which marks the product record as dirty.
This subsequently triggers an onchange on the product field, which resets the
uom field!
This fixes issue #2146. The inverse of a one2many field can be an inherited
field (_inherits). In that case, we cannot read its value with a simple
database query. Instead, we let the related field read it, but for performance
considerations we disable the prefetching of other fields.
Add an attribute 'related_sudo' (True by default) for related fields.
A related field is computed as superuser if related_sudo is True.
Add explicit related fields 'name' and 'email' on 'res.users', as these should
be readable by the public user with module website_forum.
This fixes a bug which is usually triggered in module account_followup, but
does not occur deterministically. Some recomputations of computed fields are
apparently missing. Environment objects containing recomputations todos and
kept alive by a WeakSet, are removed by the Python garbage collector before
recomputation takes place. We fix the bug by moving the recomputation todos in
a non-weakref'ed object.
The selection of records in cache for prefetching was moved to method
_read_from_database() by xmo at rev 785018cc in order to fix an access right
bug. But this introduced an issue: to explicitly avoid prefetching, you should
use read() instead of browsing records. We revert the change by xmo, without
reintroducing the bug (which apparently was fixed by another way).
When the context contains 'recompute': False, the recomputation was not even
prepared. Now both create() and write() prepare the recomputation by invoking
method modified(). The flag only controls whether method recompute() is invoked.
In addintion, the former flag 'no_store_function' was converted to the flag
'recompute', so that both create() and write() use the same flag.
Fixes#1456
At the end of _prefetch_field(), a check is made to ensure that the cache
contains something for the field to prefetch. The check was incorrect because
the cache was checked for a regular value only.
The result of _convert_to_write() is intended to be pass directly to
`write()` or returned to the client (`onchange()` and `default_get()`.
`NewId` is as special value that must not be stored into the database
or exposed to the client.
On one2many fields writing in an existing record (not when creating new record), the computed stored fields of the one2many were not re-computed correctly
Computed stored fields were marked as modified only if no_store_function was not set to True in the context. no_store_function is set when writing one2many records on an existing record.
Now, these computed stored fields are marked as to be recomputed, but are recomputed later, at the end of the existing record write
After commit f28be81, boolean columns may have more
NULL entries than before. In the (rare) cases where
a boolean column was used for an ORDER clause
(e.g. in the /shop page of website_sale), this
causes a change of the resulting ordering.
By coalescing NULL values to false in SQL,
we make the ordering consistent with what the
framework does for domain expressions with booleans,
and when reading boolean values, that is, NULL is
the same as False.
Boolean fields always default to False in 8.0,
even when they do not have explicit default values.
This causes extra queries in the form:
UPDATE <table> SET <bool_field> = false
WHERE <bool_field> IS NULL;
Those are not necessary as the ORM automatically
folds NULL booleans to False, and can be very
expensive on tables with several million rows,
as the whole table may sometimes need to be
rewritten (can take dozens of minutes)
Some many2one fields happen to have several corresponding one2many fields,
typically with different domains. It is also the case for the field 'res_id' of
mail.message, where each model inheriting from mail.thread defines a one2many
based on that field. The fix ensures that when a relational field is updated,
all its inverse fields are invalidated.
The default values are computed by evaluating fields on a new record. The fix
retrieves values from the cache earlier, because in some cases, the evaluation
of a field invalidates a formerly evaluated field.
management to access documents in notification emails, as well as for the
'view quotation' link in portal_sale module.
models: added a get_access_action method: basically, returns the action to
access a document. It uses the get_formview_action by default (form view
of the document). However for some documents we want to directly go to the
website, leading to an act_url action for some documents. This method allows
this behavior.
portal_sale: get_signup_url now uses the mail.action_mail_redirect method
instead of directly redirecting towards a portal menu. This allows to fall
back on a standard behavior.
portal_sale: get_formview_action updated, to match actions tailored for
portal users.
website_quote: get_access_action of sale order updated. If the sale order
has a template defined, the returned action is an act_url (website view
of the quotation), not the form action anymore.
mail: fixed signature + company signature in notification emails. Even without
user signature, the company signature + access link should be correct.
portal: signup url in notification emali was not using the mail redirection
as action. It is now the case.
Singleton object was required while access model properties, but search returns multiple results and hence caused traceback while accessing record.property
The existing code was buggy when writing on *2many fields with a list of
commands: the value was converted for the cache, but taking an empty recordset
as the current value of the field.
It is not useful to try to create foreign keys when the destination model is
a PostgreSQL view for example.
We already do this kind of verifications but ir.actions and transient models
but did not for _auto.
When a new record is returned as the value for a many2one on a new record, the
method Many2one.convert_to_write() now returns a NewID, and default_get() then
discards that value from its result. This makes it consistent with its former
behavior.
Manual rebase of #1547
Can be defined to False in any model to completely
disable translations for this model, when they are
irrelevant. This is useful e.g. for test classes
that use attributes that would normally be translatable.
- 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.
When computing defaults we may end up with
a falsy value that is not None (e.g. '' or False)
That value will be cast to None when being
saved in the database, depending on the column type
(e.g. saving False on a many2one actually stores NULL).
Improve the test to consider the value being written
*after* that conversion, to *really* avoid nonsensical
and expensive queries such as:
UPDATE table set col = NULL WHERE col IS NULL;
In the previous implementation of the new API fields,
both fields.Selection and fields.Reference were performing
early validation of their `value` as soon as it entered
the cache, either by being read, written, or computed.
This is a source of trouble and performance problems,
and is unnecessary, as we should consider that the database
always contains valid values. If that is not the case it
means it was modified externally and is an exception that
should be handled externally as well.
Revalidating selection/reference values can be expensive
when the domain of values is dynamic and requires extra
database queries, with extra access rights control, etc.
This patch adds a `validate` parameter to `convert_to_cache`,
allowing to turn off the re-validation on demand. The ORM
will turn off validation whenever the value being converted
is supposed to be already validated, such as when reading it
from the database.
The parameter is currently ignored by all other fields,
and defaults to True so validation is performed in all other
caes.
