Since AST was introduced to compile Qweb templates, the reset templates
functionality is not working anymore.
Actually, it does not even appear anymore as the conditions to trigger and show
the reset view behavior can't be True anymore.
Indeed, the code is still importing the old QWebException from odoo.exceptions
which is now just an empty class.
The QWebException that should now be used is the one from odoo.base.models.qweb
More than just a wrong import, the QWebException properties have completely
changed.
Since its last working version (Odoo 9.0), a lot of changes occured, mostly:
- Odoo 11.0: new model website.page, which completely changed the pages
behavior and changed the models.
- Odoo 12.0: multi-website, which introduced the Copy On Write (COW) that
redefined how we write on view in a website context. We now need to reset
copied/specific views that have no model_data_id.
This fix is for a stable version. There is some flows that can't be fixed
without a refactoring or new fields (mainly because of the arch_fs being
erased when writing on `arch`, plus we can't introduce a module reload in
stable).
The goal of this commit is to fix the basic and standard case of broken views,
which is when non-technical users are breaking the views through HTML editor.
To reset the views, we will read the original arch in the XML file, as the
dev mode is doing.
To be eligible for the reset, the broken view need an `arch_fs` set. If the
view arch has been modified anywhere else than the frontend, the `arch_fs`
will be erased and the view wont be able to be reset.
As the broken views will be specific views, we will simply read the generic
view in the XML file and write it on the specific. We can't simply remove the
specific view as we might be on a specific tree.
Specific case, in case of custom views create dropping a snippet in an oe_struc
we just delete this inehrited view to allow end user to have their page back.
In some case of bad compilation in sub template, we try to guess which inherited
view, t-called view is broken by string matching based on 'last_path_node' xpath.
Add new module test_website to add tests, it will be usefull for futur test of
install/uninstall and ...
Todo in master:
- try to track on QWebException the real template that is broken and not only
the last node from the main template.
