[Django]-Change a Django form field to a hidden field

This may also be useful: {{ form.field.as_hidden }}

an option that worked for me, define the field in the original form as:

forms.CharField(widget = forms.HiddenInput(), required = False)

then when you override it in the new Class it will keep it’s place.

Firstly, if you don’t want the user to modify the data, then it seems cleaner to simply exclude the field. Including it as a hidden field just adds more data to send over the wire and invites a malicious user to modify it when you don’t want them to. If you do have a good reason to include the field but hide it, you can pass a keyword arg to the modelform’s constructor. Something like this perhaps:

class MyModelForm(forms.ModelForm):
    class Meta:
        model = MyModel
    def __init__(self, *args, **kwargs):
        from django.forms.widgets import HiddenInput
        hide_condition = kwargs.pop('hide_condition',None)
        super(MyModelForm, self).__init__(*args, **kwargs)
        if hide_condition:
            self.fields['fieldname'].widget = HiddenInput()
            # or alternately:  del self.fields['fieldname']  to remove it from the form altogether.

Then in your view:

form = MyModelForm(hide_condition=True)

I prefer this approach to modifying the modelform’s internals in the view, but it’s a matter of taste.

For normal form you can do

class MyModelForm(forms.ModelForm):
    slug = forms.CharField(widget=forms.HiddenInput())

If you have model form you can do the following

class MyModelForm(forms.ModelForm):
    class Meta:
        model = TagStatus
        fields = ('slug', 'ext')
        widgets = {'slug': forms.HiddenInput()}

You can also override __init__ method

class Myform(forms.Form):
    def __init__(self, *args, **kwargs):
        super(Myform, self).__init__(*args, **kwargs)
        self.fields['slug'].widget = forms.HiddenInput()

If you want the field to always be hidden, use the following:

class MyForm(forms.Form):
    hidden_input = forms.CharField(widget=forms.HiddenInput(), initial="value")

If you want the field to be conditionally hidden, you can do the following:

form = MyForm()
if condition:
    form.fields["field_name"].widget = forms.HiddenInput()
    form.fields["field_name"].initial = "value"

Example of a model:

models.py

from django.db import models


class YourModel(models.Model):
    fieldname = models.CharField(max_length=255, default="default")

In your form, you can add widgets with ModelForm. To make it hidden add 'type': 'hidden' as shown below👇

forms.py

from .models import YourModel
from django import forms


class YourForm(forms.ModelForm):


    class Meta:
        model = YourModel
        fields = ('fieldname',)

        widgets = {
            'fieldname': forms.TextInput(attrs={'type': 'hidden'}),
        }

If you don’t know how to add it to your views.py file, here is some videos about it.

If you use Function Based View:

If you use Class Based View:

https://www.youtube.com/watch?v=KB_wDXBwhUA

{{ form.field}}
{{ form.field.as_hidden }}

with this jinja format we can have both visible form fields and hidden ones too.

if you want to hide and disable the field to protect the data inside. as others mentioned use the hiddenInput widget and make it disable

in your form init

example:

        if not current_user.is_staff:
           self.base_fields['pictureValid'].disabled = True
           self.base_fields['pictureValid'].widget = forms.HiddenInput()

With render_field is easy
{% render_field form.field hidden=True %}

Disclaimer: I am a junior in Django. This answer is a working solutions; however, it may contain some sub-optimal practices. If that is the case, please let me know in the comments, and I will adjust it.

To expand on Rybak’s and Zags’s answers, if you want to use the HiddenInput field in multiple places, you could create a custom hidden field class.

class MyHiddenCharField(forms.CharField):
    def __init__(self, *, required=False, **kwargs):
        self.required = required
        self.widget = forms.HiddenInput()
        super().__init__(required=False, **kwargs)

You can just use css :

#id_fieldname, label[for="id_fieldname"] {
  position: absolute;
  display: none
}

This will make the field and its label invisible.
