Build virtual environment
- Create a new virtual environment by python3
~$ python3 -m venv django_venv
- switch to this new venv
~$ source django_venv/bin/activate
(django_venv)~$
this means u have switched to a new venv
- install django into venv
pip install django
- Check installation
~$ python
(in python console)
import django
django.VERSION
Build a Django Project
(django_venv)~$ django-admin.py startproject mysite
Run a server
switch to the project path
python manage.py runserver
Then the server will be run on http://localhost:8000
if fail, try this:
python manage.py migrate
python manage.py runserver
Create Admin account
python manage.py createsuperuser
Then the server will be run on http://localhost:8000/admin
Add new app
~$ python manage.py startapp newApp
and then add it to mysite/settings.py
# Application definition
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'newApp',]
Add templates
- Add a directory
mysite$ mkdir templates
- Edit sittings.py
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(BASE_DIR, 'templates').replace('\\', '/')],
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
'django.template.context_processors.debug',
'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
],
},
},
]
- Add render function in view.py
# trips/views.py
from datetime import datetime
from django.shortcuts import render
def hello_world(request):
return render(request, 'hello_world.html', {
'current_time': datetime.now(),
})```
# Add Statics
edit settings.py
> STATICFILES_DIRS = (os.path.join(BASE_DIR, "static"),)
edit html file
{% load static %}
<html>
<head>
<link rel="stylesheet" type="text/css" href="{% static 'css/new_blah.css' %}">
</head>
<body>
# Lesson52 Use Context to modify templates
add a dict for render in views.py
from django.shortcuts import render
Create your views here.
def index(request):
context = {
'title': 'title from context',
}
return render(request, 'index.html', context)
Modify your webpage in templates like this:
### Models and Database
add connect into settings.py for mongodb
from mongoengine import connect
connect('wbsite', host = '127.0.0.1', port=27017)
edit models.py to get item info
