when i m delete my module from local modules, get like this error popup

odoo warning !

Integrity Error

The operation cannot be completed, probably due to the following:
- deletion: you may be trying to delete a record while other records still reference it
- creation/update: a mandatory field is not correctly set

[object with reference: ir.model.constraint - ir.model.constraint]

The reason of this behaviour is as follows,

Earlier you might have added one referential field and restarted the server so that field ( for example, Many2One ) created with constraint of foreign key in database. Now for some reason you changed the column name or delete that column, so the reference of that constraint is still there in postgresql database. 

Now when you going to uninstall the module, system will go to clear ir.model & ir.model.fields entries, which are belongs to that module. But the column which is not available in py but constraint will be there under ir.model.constraint model. 

The solution of this could be,

1) Go to Settings >> Technical >> Database Structure >> Model Constraints 

2) Find the constraint in the Module, which you are going to uninstall.

3) Delete the constraint.

4) Uninstall the module.

It should be work now unless you are fail to explain your problem clearly.

I am sure this will help you!
