Pycharm Django
PyCharm is a powerful Python IDE that provides excellent support for the Django framework, especially in its Professional edition (PyCharm Pro).
### Launch PyCharm and Create New Project
1. Open PyCharm, click "New Project"
2. Select "Django" on the left
3. Set project location
4. Configure Python interpreter (recommended to create new virtual environment)
!(#)
### Configure Project Parameters
* **Project name**: Use lowercase letters and underscores (e.g., DjangoProject)
* **Template language**: Default selection is Django
* **Frontend framework**: Optional based on needs (beginners may skip)
* **Enable Django admin**: Can be checked
!(#)
### Wait for Project Initialization
PyCharm will automatically:
1. Create virtual environment
2. Install latest stable Django version
3. Generate basic project structure
* * *
## Project Structure Analysis
After creation, you will see the following main files and directories:
!(#)
### Project Root Directory
* **manage.py**: Django command-line utility
* **Project-name directory** (e.g., DjangoProject/): Contains main project configuration
### Project Configuration Directory
* **__init__.py**: Identifies this as a Python package
* **settings.py**: Project configuration file
* **urls.py**: URL routing configuration
* **wsgi.py**: WSGI server configuration
### Other Important Files
* **requirements.txt**: Project dependencies file (may be auto-generated by PyCharm)
* venv/: Virtual environment directory (if virtual environment was selected)
* * *
## Run Django Development Server
### Run via PyCharm
1. Click the run configuration dropdown in the upper right corner of PyCharm
2. Select "Configure -> Edit"
!(#)
3. Ensure Django server is configured
4. Click the green run button
!(#)

### Common Issues Resolution
* **Port conflict**: Use `python manage.py runserver 8080` to specify another port
* **Database not migrated**: First run requires executing `python manage.py migrate`
* * *
## Create Django Application
### Create New Application
Enter in PyCharm's terminal:
python3 manage.py startapp myapp
!(#)
Add the application to INSTALLED_APPS in `settings.py`:
INSTALLED_APPS = [ ... 'myapp',]
!(#)
Include application routes in project `urls.py`:
## Example
from django.contrib import admin
from django.urls import path
urlpatterns =[
path('admin/', admin.site.urls),
path('myapp/', include('myapp.urls')),
]
!(#)
### Application Directory Structure
* **migrations/**: Database migration files
* **admin.py**: Admin backend configuration
* **apps.py**: Application configuration
* **models.py**: Data model definitions
* **tests.py**: Test code
* **views.py**: View functions
### Configure URL Routing in myapp Directory
Open myapp/models.py and define models. For example:
## Example
from django.db import models
class Post(models.Model):
title = models.CharField(max_length=200)
content = models.TextField()
created_at = models.DateTimeField(auto_now_add=True)
def __str__ (self):
return self.title
After saving, run python manage.py makemigrations and python manage.py migrate to update the database.
**Create Views and URLs:**
Define views in myapp/views.py:
## Example
from django.shortcuts import render
from .models import Post
def post_list(request):
posts = Post.objects.all()
return render(request,'myapp/post_list.html',{'posts': posts})
Configure URLs in myapp/urls.py (needs to be created manually):
## Example
from django.urls import path
from . import views
urlpatterns =[
path('', views.post_list, name='post_list'),
]
Create DjangoProject/templates/myapp/ folder in project root directory, then create post_list.html in that folder:
## Example
Post List
