This README.md file provides instructions for setting up a Django project with GraphQL using the provided code snippets.

Before starting, ensure you have the following installed on your system:

• Python 3
• Pip (Python package manager)

1. Create a virtual environment:

   python3 -m venv venv

2. Activate the virtual environment:

   source venv/bin/activate

3. Install Django:

   pip install django

4. Install GraphQL support using Graphene-Django:

   pip install graphene-django

5. Create a new Django project and an app:

   django-admin startproject core .
   python3 manage.py startapp books

6. Add the 'books' and 'graphene_django' app to INSTALLED_APPS in core/settings.py:

   # core/settings.py
   INSTALLED_APPS = [
       'django.contrib.admin',
       'django.contrib.auth',
       'django.contrib.contenttypes',
       'django.contrib.sessions',
       'django.contrib.messages',
       'django.contrib.staticfiles',
       'graphene_django', # Add 'graphene_django' here
       'books',  # Add 'books' here
   ]

7. Define a model in books/models.py:

   # books/models.py
   from django.db import models
   
   class Book(models.Model):
       title = models.CharField(max_length=100)
       excerpt = models.TextField()
   
       def __str__(self):
           return self.title

8. Create database tables and apply migrations:

   python3 manage.py makemigrations
   python3 manage.py migrate

9. Create a GraphQL schema file:

   touch books/schema.py

10. Populate books/schema.py with GraphQL schema definitions:

    # books/schema.py
    import graphene
    from graphene_django import DjangoObjectType
    from .models import Book
    
    class BookType(DjangoObjectType):
        class Meta:
            model = Book
            fields = ("id", "title", "excerpt")
    
    class Query(graphene.ObjectType):
        allBooks = graphene.List(BookType)
    
        def resolve_allBooks(root, info):
            return Book.objects.all()
    
    schema = graphene.Schema(query=Query)

11. Update core/urls.py to include the Books endpoint:

    # core/urls.py
    from django.contrib import admin
    from django.urls import path, include
    
    urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('books.urls'))
    ]

12. Update books/urls.py to include the GraphQL endpoint:

    # core/urls.py
    from django.urls import path
    from graphene_django.views import GraphQLView
    from books.schema import schema
    
    urlpatterns = [
        # ...
        path("graphql", GraphQLView.as_view(graphiql=True, schema=schema)),
    ]

13. Register the Book model in core/admin.py:

    # core/admin.py
    from django.contrib import admin
    from books.models import Book
    
    admin.site.register(Book)

14. Create a superuser for the admin interface:

    python3 manage.py createsuperuser

15. Visit http://localhost:8000/admin in your browser and log in with the superuser credentials you created.

16. Add few books from the admin interface:

17. Start the development server once more:

    python3 manage.py runserver

18. Visit http://localhost:8000/graphql and play with queries

Now, you have set up a Django project with GraphQL support. You can use the GraphQL endpoint at http://localhost:8000/graphql to interact with your data. The Book model is available in the admin interface for data management.
