Change a Django form field to a hidden field

Change a Django form field to a hidden field

In Django, you can change a form field to a hidden field by modifying the field in the form's Meta class and specifying widget=forms.HiddenInput. Here's how you can do it:

Let's assume you have a Django form named MyForm, and you want to change a specific field, let's say my_field, to a hidden field.

from django import forms class MyForm(forms.Form): my_field = forms.CharField(max_length=100) other_field = forms.CharField(max_length=100)

To change the my_field to a hidden field, you can subclass MyForm and update the Meta class as follows:

from django import forms class MyHiddenForm(MyForm): class Meta: # Include all fields from the original form except 'my_field' fields = [field for field_name, field in MyForm.base_fields.items() if field_name != 'my_field'] # Specify 'my_field' as a hidden field widgets = { 'my_field': forms.HiddenInput(), }

In this code:

  • We create a new form MyHiddenForm that inherits from MyForm.

  • In the Meta class of MyHiddenForm, we specify the fields we want to include in the form. In this case, we include all fields from MyForm except my_field.

  • We use the widgets attribute to specify that my_field should use the forms.HiddenInput() widget, which renders the field as a hidden input in the HTML form.

Now, when you create an instance of MyHiddenForm and render it in a template, the my_field will be rendered as a hidden input field, while the other fields will remain visible.

form = MyHiddenForm()

In your template:

<form method="post"> {% csrf_token %} {{ form.as_p }} <button type="submit">Submit</button> </form>

This will render my_field as a hidden input in the HTML form.
