🐍 Testing Django Project

📝 Django Data Input and Display Project

This project is a simple Django web application that allows users to input data through a form, save it to a database, and view it in the Django admin panel. This guide will walk you through the steps of setting up your own project based on this implementation.

🌟 Features

• User Input Form: A user-friendly form for data entry.
• Data Storage: Saves the entered data in a SQLite database.
• Admin Interface: View and manage data easily using Django's built-in admin panel.

📚 Requirements

• Python 3.x
• Django
• SQLite (default database)

📋 Overview

This repository contains a simple Django project that demonstrates how to create a RESTful API for saving and retrieving data using Django and Django REST Framework.

🛠️ Getting Started

📥 Prerequisites

Before you begin, ensure you have the following installed:

• Python (3.6 or later)
• pip (Python package manager)
• Django (latest version)
• Django REST Framework

🚀 Installation Steps

1. Install Django and Django REST Framework

   pip install django djangorestframework

2. Create a Django Project

   django-admin startproject myproject
   cd myproject
   python manage.py startapp myapp

3. Define a Model in myapp/models.py

   from django.db import models
   
   class MyData(models.Model):
       input_text = models.CharField(max_length=255)
   
       def __str__(self):
           return self.input_text

4. Create a Serializer in myapp/serializers.py

   from rest_framework import serializers
   from .models import MyData
   
   class MyDataSerializer(serializers.ModelSerializer):
       class Meta:
           model = MyData
           fields = ['input_text']

5. Create an API View in myapp/views.py

   from rest_framework import status
   from rest_framework.decorators import api_view
   from rest_framework.response import Response
   from .models import MyData
   from .serializers import MyDataSerializer
   
   @api_view(['POST'])
   def save_data(request):
       if request.method == 'POST':
           serializer = MyDataSerializer(data=request.data)
           if serializer.is_valid():
               serializer.save()
               return Response(serializer.data, status=status.HTTP_201_CREATED)
           return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

6. Add the URL for the API in myapp/urls.py

   from django.urls import path
   from .views import save_data
   
   urlpatterns = [
       path('save/', save_data, name='save_data'),
   ]

7. Include the App URLs in myproject/urls.py

   from django.urls import path, include
   
   urlpatterns = [
       path('api/', include('myapp.urls')),
   ]

8. Run Migrations

   python manage.py makemigrations
   python manage.py migrate
   python manage.py runserver

🌐 Accessing the API

Your Django API is now ready to accept POST requests at http://127.0.0.1:8000/api/save/ to save data in the database.

⚠️ Troubleshooting

If you encounter issues:

• Install CORS headers:

  pip install django-cors-headers

• Update your settings.py:

  INSTALLED_APPS = [
      ...
      'corsheaders',
  ]
  
  MIDDLEWARE = [
      'corsheaders.middleware.CorsMiddleware',
      ...
  ]
  
  CORS_ALLOW_ALL_ORIGINS = True

🔍 Checking the Database

1. Using Django Admin

   • Create a superuser:

     python manage.py createsuperuser

   • Navigate to http://127.0.0.1:8000/admin and log in.

2. Using Django Shell

   python manage.py shell
   from myapp.models import MyData
   MyData.objects.all()  # Lists all saved entries

📦 Adding a Data Retrieval Endpoint

To retrieve saved data in your Flutter app:

1. Create a GET Endpoint in your Django API:

   from rest_framework.views import APIView
   from rest_framework.response import Response
   from .models import MyData
   from .serializers import MyDataSerializer
   
   class MyDataList(APIView):
       def get(self, request):
           texts = MyData.objects.all()
           serializer = MyDataSerializer(texts, many=True)
           return Response(serializer.data)

2. Update your URL Configuration

   from django.urls import path
   from .views import MyDataList
   
   urlpatterns = [
       path('data/', MyDataList.as_view(), name='mydata_list'),
   ]

🗄️ Optional: Admin Registration

To view your model in the Django admin:

• Open myapp/admin.py:

  from django.contrib import admin
  from .models import MyData
  
  admin.site.register(MyData)

📄 Conclusion

This project demonstrates how to create a basic Django API to save and retrieve data. You can build upon this foundation to create more complex applications.
