Django simple form "object has no attribute 'is_hidden'"

Question

I'm trying to render a simple form with no db models but I am getting error. Following is the code:

from django import forms
from django.utils.safestring import mark_safe
class ContactForm(forms.Form):
    category_options = (
        ('select category', '--Select Category--'),
        ('fire safety', 'Fire Safety'),
        ('batteries/solar panels', 'Batteries/Solar Panels'),
        ( 'cctv systems','CCTV Systems')
    )
    category = forms.ChoiceField(label="Select a Category", choices=category_options, required=True)
    full_name = forms.CharField(required=False)
    email = forms.EmailField()
    phone = forms.CharField(widget=forms.IntegerField)
    message = forms.CharField(widget=forms.Textarea(attrs={'cols': 10, 'rows': 10}))

    def clean_email(self):
        email = self.cleaned_data.get('email')
        
        return email

I'm not getting the phone field right. I need to add validation for phone numbers and couldn't figure out the right way to use widget for IntegerField.

I need to find the accurate way of adding a phone field.

I'm getting the error:

AttributeError at /contact/
'IntegerField' object has no attribute 'is_hidden'

I get following results when I use

phone = forms.CharField(widget=forms.NumberInput)

My html generated from the python code for different fields is following:

<p> 
<label for="id_email">Email:</label>
<input id="id_email" name="email" type="email">
</p>

<p> 
<label for="id_phone">Phone:</label>
<input id="id_phone" name="phone" type="number">
</p>

Both my fields above are generated with python code but email field is applying template css properly. But "Phone" field is not rendering css.

Please advise.

Just use CharField and do all the validations inside `def clean_phone(self):` method. — Avinash Raj, Mar 08 '16 at 05:49
Avinash I did that but I thought there could be some built in way to get it done. — Shazia Nusrat, Mar 08 '16 at 15:52

forms.IntegerField is not a widget but a field type on form.

What you need is a forms.NumberInput

phone = forms.CharField(widget=forms.NumberInput)

By your recommendation see above what I am getting. It is not getting my css instead its giving me a field that is not inheriting css at all. I've pasted the result as snapshot in original question above. – Shazia Nusrat Mar 08 '16 at 05:09
Can you also paste the HTML for the `phone` field and other fields as well? And, also how are you rendering this form in the view? – AKS Mar 08 '16 at 05:11

Please update this in question so it is available for everyone. And, please also include the css for both the inputs `email` and `phone` fields. – AKS Mar 08 '16 at 05:18

Please add the css as well. Because now your form is rendering and just the css for two fields is different. It could very well be that the css for `input[type=number]` is not set as it has been for other type of fields. – AKS Mar 08 '16 at 09:55

You can use

phone = forms.CharField(widget=forms.TextInput(
      attrs={
          'type' : 'number',
          'class' : 'your_class'
      }))

You assign the form field forms.IntegerField to "widget" which is wrong:

class ContactForm(forms.Form):
    # ...                               # Wrong
    phone = forms.CharField(widget=forms.IntegerField)
    # ...

So, instead, you need to assign the widget forms.NumberInput to "widget" which is correct:

class ContactForm(forms.Form):
    # ...                               # Correct
    phone = forms.CharField(widget=forms.NumberInput)
    # ...
