Django: __init__() got an unexpected keyword argument 'choices'

Question

I'm trying to create a form, and pass on the values entered by the use into a database.

models.py

from django.db import models

class Evangelized(models.Model):
    full_name = models.CharField(max_length = 128)
    email = models.EmailField()
    mobile_no = models.CharField(unique = True, max_length = 128)
    twitter_url = models.CharField(unique = True, max_length = 128)
    GENDER_CHOICES = (('M', 'Male'), ('F', 'Female'), ('U', 'Unisex/Parody'))
    gender = models.CharField(max_length=1, choices=GENDER_CHOICES)
    AREA_CHOICES = (('Govt', 'Govt'), ('Entertainment', 'Entertainment'), ('Automobile', 'Automobile'),
                        ('Careers', 'Careers'), ('Books', 'Books'), ('Family', 'Family'), ('Food', 'Food'),
                            ('Gaming', 'Gaming'), ('Beauty', 'Beauty'), ('Sports', 'Sports'), ('Events', 'Events'),
                                ('Business', 'Business'), ('Travel', 'Travel'), ('Health', 'Health'), ('Technology','Technology'))
    area_of_interest = models.CharField(choices = AREA_CHOICES, max_length = 128)
    other_area_of_interest = models.CharField(blank = True, max_length = 128)
    city = models.CharField(max_length = 128)
    BOOL_CHOICES = ((True, 'Yes'), (False, 'No'))
    other_social_accounts = models.BooleanField(choices = BOOL_CHOICES, default = None)
    questions = models.CharField(blank = True, max_length = 1280)
    about_yourself = models.CharField(blank = False, max_length = 1280)
    referrer = models.CharField(max_length = 128)

forms.py

   from django import forms
from rango.models import Evangelized

class EvangelizedForm(forms.ModelForm):
    full_name = forms.CharField(help_text="Full Name")
    email = forms.CharField(help_text="Email ID")
    mobile_no = forms.CharField(help_text="Mobile number")
    twitter_url = forms.CharField(help_text="Twitter URL")
    gender = forms.ChoiceField(widget=forms.RadioSelect(), 
                 choices=Evangelized.GENDER_CHOICES, help_text="Gender")
    area_of_interest = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple(),
                                                    choices=Evangelized.AREA_CHOICES, help_text="Areas of interest(Upto 3)")
    """def clean_area_of_interest(self):
        if len(self.cleaned_data['area_of_interest']) > 3:
            raise forms.ValidationError('Select no more than 3.')
        return self.cleaned_data['area_of_interest']"""
    other_area_of_interest = forms.CharField(help_text="Other area of interest")
    city = forms.CharField(help_text="City")
    other_social_accounts = forms.CharField(widget=forms.RadioSelect(),choices=Evangelized.BOOL_CHOICES, help_text="Do you have other social accounts?", max_length=128)
    questions = forms.CharField(help_text="Do you have any questions?")
    about_yourself = forms.CharField(help_text="Tell us about yourself")
    referrer = forms.CharField(help_text="I heard about this platform via:")

    class Meta:
        model = Evangelized
        fields = ('full_name', 'email', 'mobile_no', 'twitter_url', 'gender', 'area_of_interest', 'other_area_of_interest', 'city', 'other_social_accounts',
                    'questions', 'about_yourself', 'referrer')

views.py

def fillform(request):
    if request.method == 'POST':
        form = EvangelizedForm(request.POST)
        if form.is_valid():
            form.save(commit = True)
            return index(request)
        else:
            form.errors
    else:
        form = EvangelizedForm()

    return render(request, 'rango/fillform.html', {'form': form})

However, I'm encountering the following error:

Exception Type: TypeError at /rango/
Exception Value: __init__() got an unexpected keyword argument 'unique'

What seems to be wrong with my code? And what does this error signify?

EDIT:

I've modified the source code of my forms.py file, and also made a slight chance in the original title. Seems like the choices key in the parameters on my form fields is generating an error. However, the code is syntactically correct, right?

Solution

Form fields like your mobile_no for example don't have a unique argument. Only model fields have that. You have to remove all unique arguments from your form model.

I have edited the question and the original post as well based on changing my code on your suggestions.

[Klaus D.]

This time you used the wrong field type one other_social_accounts it should be a ChoiceField.

[Klaus D.]

Some other fields as well, check docs.djangoproject.com/en/1.8/ref/forms/fields if the field type you are using have a choices argument.

[Daniel Roseman]

Alternatively, use ChoiceField rather than CharField.
