The Django forms functionality generates the html code for my form fields.
I would like to change some attributes or add some for a specific field from that form.
For example I would like to specify a class for a field.
How can I do that?
I read an answer on SO that I could do it like this:
city = forms.CharField(widget=forms.TextInput(attrs={'class':'anyclass'}))
but i get an error, that attrs does not exist or is undefined...
UPDATE
Here is my forms.py
from django import forms from HelloUprise.models import Goal from django.contrib.auth.models import User
class GoalForm(forms.ModelForm):
deadline = forms.DateField(widget=forms.DateField(attrs={'class': 'form-control'}))
class Meta:
model=Goal
fields = ['goal', 'description', 'deadline', 'priority']
Here is the error:
TypeError at /
__init__() got an unexpected keyword argument 'attrs'

You haven't done what you showed in the example. Instead of using a widget, you're trying to pass another instance of the field. That doesn't work, as the error shows.
It should be:
deadline = forms.DateField(widget=forms.DateInput(attrs={'class': 'form-control'}))
note the use of DateInput instead of DateField.
