Monkey-patch the create of BaseModel in order to create translation lines
|
|
on translatable fields.
|
|
|
|
Actually, the original behavior is quite strange. Here it is:
|
|
I'm logged in with en_US language.
|
|
I create a record, with a (translatable) title 'My title'
|
|
I check the source in database (table of the object), that's 'My title'
|
|
I check the translation lines for the en_US language, no line
|
|
I write on my record the title 'My title updated'
|
|
I check the source in database, that's 'My title updated'
|
|
I check the translation lines for the en_US language, no line
|
|
|
|
I'm logged in with fr_FR language
|
|
I create a record, with a (translatable) title 'Mon titre'
|
|
I check the source in database (table of the object), that's 'Mon titre'
|
|
I check the translation lines for the fr_FR language, no line
|
|
I write on my record the title 'Mon titre mis à jour'
|
|
I check the source in database, that's 'Mon titre' (unchanged)
|
|
I check the translation lines for the fr_FR language, I have a line with 'Mon titre mis à jour'
|
|
|
|
As you can see, the write method create translation lines for other
|
|
languages than en_US, that's correct. The create method does not,
|
|
and it has to do it.
|
|
|
|
OpenERP seems to assume that the en_US should be the reference
|
|
language, so lets assume it completely, and generate the french
|
|
translation line directly when we enter the value.
|
|
|
|
That's weird, because, if I create a record in french, the source
|
|
will be the french value (of course), but programmatically, I do not
|
|
have any means to know that someone entered a french translation.
|
|
|
|
A simple scenario where the bug will occurs:
|
|
|
|
User A is logged in with fr_FR
|
|
User A creates a product with a name 'Marteau'
|
|
User B is logged in with en_US
|
|
User B modifies the product 'Marteau' to be 'Hammer'
|
|
=> The french translation is lost.
|
|
|
|
It won't occurs in this slightly modified scenario:
|
|
|
|
User A is logged in with fr_FR
|
|
User A creates a product with a name 'Martea' (typo)
|
|
User A modifies the product 'Martea' to be 'Marteau'
|
|
User B is logged in with en_US
|
|
User B modifies the product 'Marteau' to be 'Hammer'
|
|
=> The french translation isn't lost, because the write has
|
|
correctly generated the french translation line
