Three ways to change widget in Django ModelForm

The problem: replace TextInput with Textarea.

models.py:

from django.db import models


class MyModel(models.model):
    title = models.CharField(max_length=1000)
    description = models.CharField(
        max_length=5000, help_text='Your amazing description')

forms.py:

from django import forms

from .models import MyModel


class MyForm(forms.ModelForm):

    description = forms.CharField(widget=forms.Textarea)

    class Meta:
        model = MyModel

This is the worst one. Why? Help text specified in the model field will be not visible in form.

Better way:

from django import forms

from .models import MyModel


class MyForm(forms.ModelForm):

    class Meta:
        model = MyModel

    def __init__(self, *args, **kwargs):
        super(MyForm, self).__init__(*args, **kwargs)
        self.fields['description'].widget = forms.Textarea

And the best:

from django import forms

from .models import MyModel


class MyForm(forms.ModelForm):

    class Meta:
        model = MyModel
        widgets = {
            'description': forms.Textarea,
        }
