Can i use something similar to pre process my data? like, changing the name, like windows when you try to save a file with the same name for example: filename, if you write "filename" then windows is gonna save "filename(1)"

Hi, I don't understand about the part that function check_name() that search([('name','=',rec.name),('id','!=',rec.id)])
Should it be enough with ('name','=',rec.name)? When i check with actual code, search([('name','=',rec.name),('id','!=',rec.id)]) work, but ('name','=',rec.name) didn't.
Can you explain this part please? Thanks you sir.

[@futhedude4848]

Oh i get it, it's because when in constrain, we have to ignore the current record, or else, it will always return the record.
This only happen in constrain.

i have 2 modules that are connected in many2many. One is inventory, the other is employees. How do I make it that 1 employee can have many items from inventory, but 1 item can only be used by 1 person at a time. Thanks

[@OdooMates]

by using this contrains itself, you can achieve this, add constrains for the field, then using search orm, check record is having another relation, then show message

Hi sir, i've a problem that i made a field called "doctor_id" and many2one to res.users. Then use constrain on that field to check if doctor_id is already exists.
But now, the constrain trigger every action i do in doctor model, such as go back to doctors list. How to ignore that, and only trigger the constrain in "save" action?
Thanks.
