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!

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!
