Create View refers to a view (logic) to create an instance of a table in the database. It is just like taking an input from a user and storing it in a specified table. Django provides extra-ordinary support for Create Views but let’s check how it is done manually through a function-based view. This article revolves around Create View which involves concepts such as Django Forms, Django Models.
For Create View, we need a project with some models and forms which will be used to create instances of that model.

Django Create View – Function Based Views

Illustration of How to create and use create view 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.

After you have a project and an app, let’s create a model of which we will be creating instances through our view. In geeks/models.py,




# import the standard Django Model
# from built-in library
from django.db import models
   
# declare a new model with a name "GeeksModel"
class GeeksModel(models.Model):
  
    # fields of the model
    title = models.CharField(max_length = 200)
    description = models.TextField()
  
    # renames the instances of the model
    # with their title name
    def __str__(self):
        return self.title


After creating this model, we need to run two commands in order to create Database for the same.

Python manage.py makemigrations
Python manage.py migrate

Now we will create a Django ModelForm for this model. Refer this article for more on modelform – Django ModelForm – Create form from Models. create a file forms.py in geeks folder,




from django import forms
from .models import GeeksModel
  
  
# creating a form
class GeeksForm(forms.ModelForm):
  
    # create meta class
    class Meta:
        # specify model to be used
        model = GeeksModel
  
        # specify fields to be used
        fields = [
            "title",
            "description",
        ]


Now we have everything ready for back end. Let’s create a view and template for the same. In geeks/views.py,




from django.shortcuts import render
  
# relative import of forms
from .models import GeeksModel
from .forms import GeeksForm
  
  
def create_view(request):
    # dictionary for initial data with 
    # field names as keys
    context ={}
  
    # add the dictionary during initialization
    form = GeeksForm(request.POST or None)
    if form.is_valid():
        form.save()
          
    context['form']= form
    return render(request, "create_view.html", context)


Create a template in templates/create_view.html,




<form method="POST" enctype="multipart/form-data">
  
    <!-- Security token -->
    {% csrf_token %}
  
    <!-- Using the formset -->
    {{ form.as_p }}
      
    <input type="submit" value="Submit">
</form>


Let’s check what is there on http://localhost:8000/
django-create-view-function-based

Now let’s try to enter data in this form,
create-view-function-enter-data

Bingo.! Create view is working and we can verify it using the instance created through the admin panel.

This way one can create create view for a model in Django.
