Passing widget attributes dictionary into Django Form

Question

I am using forms in my Django project, and I want to specify some of the attributes of the widget that I use in my form but am having trouble figuring out how to pass in the attrs dictionary to the widget.

The view.py:

form_schedule_start = WINDOW_Schedule_Form(section_label=" Start",required=True,initial=scheduleStart,attributes={'class':"form-control",'placeholder':".col-md-4"})

The form:

class WINDOW_Schedule_Form(forms.Form):
  def __init__(self,*args,**kwargs):
    section_label = kwargs.pop('section_label')
    initial_value = kwargs.pop('initial')
    required_value = kwargs.pop('required')
    attributes = kwargs.pop('attributes')

    super(WINDOW_Schedule_Form,self).__init__(*args,**kwargs)
    self.fields['WINDOW_Schedule'].label=mark_safe(section_label)
    self.fields['WINDOW_Schedule'].initial=initial_value
    self.fields['WINDOW_Schedule'].required=required_value
    self.fields['WINDOW_Schedule'].attrs=attributes


  WINDOW_Schedule = forms.CharField(widget=forms.TextInput())

Normally you would just do

WINDOW_Schedule = forms.CharField(widget=forms.TextInput(attrs={'class':"form-control text-center",'placeholder':".col-md-8"}))

but I want to be able to specify the 'class' and 'placeholder' attributes in my views.py.

I keep getting an error that attributes is not defined though. Can anyone tell me what I'm doing wrong?

Where do you get the error? At the point where `kwargs.pop('attributes')` is called? — Alain, Jul 22 '15 at 19:37
@Alain yes, I get it where `kwargs.pop('attributes')` is called. — kdubs, Jul 22 '15 at 20:40
This is interesting. According to the definition of the pop() function for dictionaries (see https://docs.python.org/2/library/stdtypes.html), a key error should be raised when you execute `required_value = kwargs.pop('required')` since there is no key 'required' and you don't assign a default. — Alain, Jul 23 '15 at 01:18
@Alain I think that is a copy/paste error on my part. I have `required` defined in my code - see updated question. — kdubs, Jul 23 '15 at 18:19
