[Manuel Marquez]

Hello, I am having a problem to extend a field of a model.
Can someone tell me the right way?

Thanks.

I am not sure what you mean by "extend a field of a model."  If a model is defined in another module, and you want to change the attributes of one of its fields, the place to do it is in by overriding the model's __setup__ method.  For example, something like AModel.the_field.states.update({'readonly': True}).
