Django form - set label
PythonDjangoInheritanceDjango FormsPython Problem Overview
I have a form that inherits from 2 other forms. In my form, I want to change the label of a field that was defined in one of the parent forms. Does anyone know how this can be done?
I'm trying to do it in my __init__
, but it throws an error saying that "'RegistrationFormTOS' object has no attribute 'email'". Does anyone know how I can do this?
Thanks.
Here is my form code:
from django import forms
from django.utils.translation import ugettext_lazy as _
from registration.forms import RegistrationFormUniqueEmail
from registration.forms import RegistrationFormTermsOfService
attrs_dict = { 'class': 'required' }
class RegistrationFormTOS(RegistrationFormUniqueEmail, RegistrationFormTermsOfService):
"""
Subclass of ``RegistrationForm`` which adds a required checkbox
for agreeing to a site's Terms of Service.
"""
email2 = forms.EmailField(widget=forms.TextInput(attrs=dict(attrs_dict, maxlength=75)), label=_(u'verify email address'))
def __init__(self, *args, **kwargs):
self.email.label = "New Email Label"
super(RegistrationFormTOS, self).__init__(*args, **kwargs)
def clean_email2(self):
"""
Verifiy that the values entered into the two email fields
match.
"""
if 'email' in self.cleaned_data and 'email2' in self.cleaned_data:
if self.cleaned_data['email'] != self.cleaned_data['email2']:
raise forms.ValidationError(_(u'You must type the same email each time'))
return self.cleaned_data
Python Solutions
Solution 1 - Python
You should use:
def __init__(self, *args, **kwargs):
super(RegistrationFormTOS, self).__init__(*args, **kwargs)
self.fields['email'].label = "New Email Label"
Note first you should use the super call.
Solution 2 - Python
Here's an example taken from Overriding the default fields:
> from django.utils.translation import ugettext_lazy as _
>
> class AuthorForm(ModelForm):
> class Meta:
> model = Author
> fields = ('name', 'title', 'birth_date')
> labels = {
> 'name': _('Writer'),
> }
> help_texts = {
> 'name': _('Some useful help text.'),
> }
> error_messages = {
> 'name': {
> 'max_length': _("This writer's name is too long."),
> },
> }
Solution 3 - Python
You can set label
as an attribute of field when you define form.
class GiftCardForm(forms.ModelForm):
card_name = forms.CharField(max_length=100, label="Cardholder Name")
card_number = forms.CharField(max_length=50, label="Card Number")
card_code = forms.CharField(max_length=20, label="Security Code")
card_expirate_time = forms.CharField(max_length=100, label="Expiration (MM/YYYY)")
class Meta:
model = models.GiftCard
exclude = ('price', )
Solution 4 - Python
You access fields in a form via the 'fields' dict:
self.fields['email'].label = "New Email Label"
That's so that you don't have to worry about form fields having name clashes with the form class methods. (Otherwise you couldn't have a field named 'clean' or 'is_valid') Defining the fields directly in the class body is mostly just a convenience.
Solution 5 - Python
Try on Models.py
email = models.EmailField(verbose_name="E-Mail Address")
email_confirmation = models.EmailField(verbose_name="Please repeat")
Solution 6 - Python
It don't work for model inheritance, but you can set the label directly in the model
email = models.EmailField("E-Mail Address")
email_confirmation = models.EmailField("Please repeat")
Solution 7 - Python
if all other solutions don't work, this one worked for me (to change the user class label to django contrib auth)
#in models.py
User._meta.get_field('username').verbose_name = "new name"
