To reproduce the issue:
- Go to website > Add language > Add blocks to your homepage and
translate it.
- Make translations on the "Contact us" page (or a new custom page).
- Install a new app > The translation of the homepage is lost (only on
homepage).
Explanation:
After [1], The `_load_module_terms()` method was updated on website
module to copy translations from base to specific views when module
translation is loaded. And since [2], the translated field's column is
either NULL or a JSON dict mapping language codes to text (the field's
value in the corresponding language).
To explain what happens exactly when new app is installed, let's suppose
we want to load module translation for the config {'en_US', 'fr_BE'} in
the following situations:
S1 (e.g. "Contact us" page):
-=-=-=-=-=-=--=-=-=-=-=-=-=-
```
generic_arch_db = {
'en_US': '<div>Generic (EN)</div>',
'fr_BE': '<div>Generic (FR)</div>'
}
- specific_arch_db = {
'en_US': '<div>Specific (EN)</div>',
'fr_BE': '<div>Specific (FR)</div>'
}
```
`_load_module_terms()` will copy translations for 'fr_BE' from generic
to specific `arch_db` (using generic translation dictionary).
result:
```
new_specific_arch_db = {
'en_US': '<div>Specific (EN)</div>',
'fr_BE': '<div>Updated Specific (FR)</div>'
}
```
S2 (new custom page):
-=-=-=-=-=-=--=-=-=-=
```
generic_arch_db = NULL
specific_arch_db = {
'en_US': '<div>Specific (EN)</div>',
'fr_BE': '<div>Specific (FR)</div>'
}
```
result:
Nothing to do here (only specific version), the specific translation
will not be updated.
S3 (e.g. website homepage):
-=-=-=-=-=-=--=-=-=-=-=-=-=
The generic view has no translated `arch_db` (only the 'en_US' version):
```
generic_arch_db = {'en_US': '<div>Generic (EN)</div>'}
specific_arch_db = {
'en_US': '<div>Specific (EN)</div>',
'fr_BE': '<div>Specific (FR)</div>'
}
```
`_load_module_terms()` will copy generic translations only for languages
available on "generic_arch_db" and the 'fr_BE' version will be lost.
result:
`new_specific_arch_db = {'en_US': '<div>Specific (EN)</div>'}`
The goal of this commit is to prevent this behaviour by keeping the
specific translated `arch_db` even when the generic value has no content
for the translation language.
Remark: This behaviour occurred while loading module translations,
as a consequence, the specific translations are also lost when the
website module is updated.
