Django – Handling multiple forms in single view


We sometimes need to handle multiple forms in a single function or view. In this article, we will see how to write a function which will handle two forms at the same time and in same view. It is handy in many cases; we will handle more than two forms too.

Create a Django project and an app, I named the project "multipleFormHandle" and the app as "formhandlingapp".

Do some basic stuff like including app in settings.py INSTALLED_APPS and include app's url in project's url.

Now create forms.py in app and a "templates" folder in the app directory. Add home.html in templates.

Install the multi-form_view library −

pip install multi_form_view

Example

Now in urls.py of app −

from django.urls import path,include
from . import views
urlpatterns = [
   path('',views.SchoolData.as_view(),name='home'),
]

Here, we setup views and use our viewset as view. We are going to use viewset here.

In models.py −

from django.db import models

# Create your models here.

class StudentData(models.Model):
   name=models.CharField(max_length=100)
   standard=models.CharField(max_length=100)
   section=models.CharField(max_length=100)

class TeachertData(models.Model):
   name=models.CharField(max_length=100)
   ClassTeacherOF=models.CharField(max_length=100)
   Salary=models.CharField(max_length=100)

We created two models because we are going to save forms data in models.

In forms.py −

from django import forms
from .models import TeachertData,StudentData

class StudentForm(forms.ModelForm):
   class Meta:
      model=StudentData
      fields="__all__"

class TeacherForm(forms.ModelForm):
   class Meta:
      model=TeachertData
      fields="__all__"

Here, we created model forms which we will render on the frontend from our view.

In home.html −

<!DOCTYPE html>
<html>
   <head>
      <title>tut</title>
   </head>
   <body>
      <form method="post" enctype="multipart/form-data">
         {% csrf_token %}

         <label><h3>Teacher</h3></label>
         //accessing form 1 from view
         {{ forms.teacher_form.as_p }}
         <label><h3>Student</h3></label>
         //accessing form 2 from view
         {{ forms.student_form.as_p }}
         <input type="submit" value="submit"/>
      </form>
   </body>
</html>

It is our frontend where we render two Django forms under a single form element and with a single submit button.

I will not add style, because here we are learning the concept and the way to do that.

In views.py −

from django.shortcuts import render
from .forms import StudentForm,TeacherForm
from django.views.generic.list import ListView
from django.urls import reverse

from multi_form_view import MultiModelFormView
# Create your views here.
class SchoolData(MultiModelFormView):
   form_classes = {
      'student_form' : StudentForm,
      'teacher_form' : TeacherForm,
   }
   template_name = 'home.html'
   def get_success_url(self):
      return reverse('home')
   def forms_valid(self, forms):
      student = forms['student_form'].save(commit=False)
      teacher=forms['teacher_form'].save(commit=False)
      return super(SchoolData, self).forms_valid(forms)

Here we created a viewset, we define two forms to render one is student form and the other is teacher form. We defined the HTML which we have to render. We define what to do when a form is submitted under get_success_url. In form_valid, we save the form data and verify if both the forms are right or not.
