There were inconsistencies in the calls to `_render`.
* the view context could contain information that misled developers.
Indeed, the context and value of the view are not supposed to be found
in the rendering. Thus by calling `ir.qweb` with the name of the
template, we ensure that there is no unwanted information and in
addition the cache key is that of the name of the template which saves
a query.
* the context used for rendering was modified by a method on
`ir.ui.view`, except this is not information used by this model. There
is now a `_prepare_environment` method residing on `ir.qweb`. This
method allows to modify the value dictionary as well as the context in
which the rendering will be done. This preparation of the data as well
as my security check is done only once per rendering. This also saves
some queries
* Freeze options for rendering were inconsistent. It could be that
options on which rendering depends were not part of the cache key. Thus,
depending on the user who generated the generation of the rendering
function, there was or was not information in the template. For example
for automatic branding. This is no longer possible, because it is the
context that is used. The options serving as a cache key are only
recorded for information (for the profiling system for example). A
simplification of the `ir.qweb.field` models could be made.
The report rendering and call `ir.qweb` instead of `ir.ui.view`.
Part-of: odoo/odoo#85110
Slug and unslug API is now available in http_routing. Indeed there is no
link to any website or any reason to not support slufigied URLs when
website is not installed. A new unslug_url method is added as a tool
coming from an embedded method from website. Doing it allows to have all
slug related methods defined at the same point.
Support of slug and unslug in qweb rendering is also moved directly in
http_routing version of ir_ui_view instead of website inheritance. This
is done in order to keep things coherent.
Some code from website about ModelConverter is also moved. Indeed both
versions of ir_http uses some kind of placeholder to store the uid
when converting urls to python. This commit unifies it by using the
website one directly in base to simplify the override.
This commit also updates all module importing slug. Enterprise modules
will have to be updated, see related commit.
This module will contain http routing capabilities that are not
necessarily linked to a website. This covers for example code related
to language management in URLs or slugify support.
Advanced http routing are not moved in base in order to keep the core
simple. It is not moved in web because this module should contain only
interface and not http / routing code. http_routing module will therefore
be used to hold those features.
This commit only adds a void module, future commits will gradually add
the various features through dedicated MOV commits.
