Override value of a TextField class method.

[Fabio da Silva Pedro]

Hi everyone!

this is an excerpt line from my model

observacoes = models.TextField(null=True, blank=True, verbose_name='Informações complementares')

How i do override a field type TextField and change your internal class value Textarea, this is a widget from TextField Class and override this method below:

def __init__(self, attrs=None):
    # Use slightly better defaults than HTML's 20x2 box
    default_attrs = {'cols': '40', 'rows': '10'}
    if attrs:
        default_attrs.update(attrs)
    super().__init__(default_attrs)

I need change value from default_attrs = {'rows':'10'} for {'rows':'4'} 

 How can I override this in my model or in my view?

Thanks for watching!

Easy. You need to provide attrs as dict to the new object.

Ok, I thought about that too, but I don't know how to do it, I copied the whole method and pasted it into my model and tried to access its superclass, but I didn't get it!
Maybe I'm doing something wrong yet.

Would you have any examples for me?

I can easily do this with jQuery, but I want to learn how to do this using just Django and for that I still have little experience in method override.

best regards!

Hint:.. __init__ is a constructor not any method.
