Django-Admin: CharField as TextArea

Question

I have

class Cab(models.Model):
    name  = models.CharField( max_length=20 )
    descr = models.CharField( max_length=2000 )

class Cab_Admin(admin.ModelAd         


        

Answer 1

You don't need to create the form class yourself:

from django.contrib import admin
from django import forms

class MyModelAdmin(admin.ModelAdmin):
    def get_form(self, request, obj=None, **kwargs):
        kwargs['widgets'] = {'descr': forms.Textarea}
        return super().get_form(request, obj, **kwargs)

admin.site.register(MyModel, MyModelAdmin)

See ModelAdmin.get_form.
