Now we reach the veterans talk and remembering. Time flies lads !

My two cents on this topic. I confirm what Daniel and Graeme said. The reason behind was to quickly find back the custom fields and models added by the interface and avoid searching in the code for the field and model definition. 

Anyway such modifications should be banned for the sake of the project and the mental health 😉

Yes but it is still exactly the same case. A model or field that is not part of a module. There is zero technical difference between creating a field via RPC and via UI. Afterall the UI is just sending the same RPC calls to the server. It absolutely does not apply to community developed modules in any way whatsoever, and it is absolutely required for any field created outside of a module (such that it gets ignored rather than removed in certain operations, it is essentially treated as data). And yes it existed in v5, and it was a major feature. This was the times of OpenBravo taking primacy with their dynamic low code DDL java thing, and OpenERP had a precursor to Studio in it. They even had a website openerp.tv dedicated to tutorials on how to do it.

Well, this is not the only instance of that magical x_ I came across this (at least if I remember well) already in times of OpenERP Version 5 or so. Here for instance it again seems to be more related to backend UI changes and some reasoning is also provided by Ray

I took a quick read and yes it is a misunderstanding of the documentation. If reading a specific section about creating custom models over RPC calls, do not try and apply it to module development in general. All the documentation is correct as is Daniel's statement. Just a misread.

Before Odoo studio, there was another frontend editor, like way back in v5. But it is only for fields created through the UI, not modules. Never modules, it would be a nonsense.  The only time you would use in a module is if it contained dynamic field creation, e.g. like studio, or you have some kind of variable dynamic model like say custom field service worksheets. I think this is simply a misunderstanding of the documentation.

Thanks Pedro, thanks Christian and Francesco for your comments,

i think the first appearance of that magical "x_" was long before Odoo 
Studio even existed but i do definitely agree that backend UI changes 
done with Odoo Studio (or earlier through Developer Tools and Plain BE 
functions) should be avoided in any production grade DB. However, 
technically forbid to use that "methods" is not all too simple (if the 
customer pretends to have certain rights on his landscape) or comes from 
an origin where nobody even told them ;-)

To me it seems (i.e. would be my conclusion) that Odoo S.A. always 
wanted to have that "x_" prefix and the community mostly ignored it (if 
i remember well, i have occassionaly seen app store modules that 
followed this 'requirement').

Now what bothers me most is that Odoo S.A. isn't consistent either on 
the matter and obviously never forced to comply (would have been easily 
possible).

So probably we we better follow the "wisdom of the crowd" altogether and 
continue to ignore that "magic convention".

Best Frederik
