After creating a Django Form, if one requires some or all fields of the form be filled with some initial data, one can use functionality of Django forms to do so. It is not the same as a placeholder, but this data will be passed into the view when submitted. There are multiple methods to do this, most common being to pass the data dictionary when we initialize the form in Django view. Other methods include passing initial values through form fields or overriding the __init__ method.

How to pass initial data to a Django form ?

Illustration of passing initial data using an Example. Consider a project named geeksforgeeks having an app named geeks.

Refer to the following articles to check how to create a project and an app in Django.

from django import forms
// creating a django form
class GeeksForm(forms.Form):
    title = forms.CharField()
    description = forms.CharField()
    available = forms.BooleanField()
    email = forms.EmailField()

Now to render this form we need to create the view and template which will be used to display the form to user. In geeks/, create a view

from django.shortcuts import render
from .forms import GeeksForm
# creating a home view
def home_view(request):
    context = {}
    form = GeeksForm(request.POST or None)
    context['form'] = form
    return render(request, "home.html", context)

and in templates/home.html,

<form method="POST">
    {% csrf_token %}
    {{ form.as_p }}
    <input type="submit" value="Submit">

Now let’s display the form by running

Python runserver

    # field names as keys
    initial_dict = {
        "title" : "My New Title",
        "description" : " A New Description",
    # add the dictionary during initialization
    form = GeeksForm(request.POST or None, initial = initial_dict)
    context['form']= form
