在Eclipse中创建Django 简单例子

Not be convinent to Type Chinese in Fedora 20, Using English to record the process of how I create my first Django example.

1 Create Django Project

1.1 File -->New -->Project -->Pydev Django project ---> Next

     type Project name and select SQList as database

1.2 Run click 'manage.py' -->Run as --> Run configurations -->Arguments

     Input 'runserver 9000' in the Program arguments tab.

     9000 is the port I'm using.

1.3 Create new Pydev module view.py and input the following:

   from django.http import HttpResponse
from django.shortcuts import render_to_response
import mysql.connector

def hello(request):
   #return HttpResponse("Hello world,My FristDJ1")
   #names=['seanL','a','b','c']

   cnx = mysql.connector.connect(user='root', password='xxx',
                             host='127.0.0.1',
                             database='test')
   cursor = cnx.cursor()
   cursor.execute('select F2 from test.xx')

   names = [row[0] for row in cursor.fetchall()]

   cnx.close()

   return render_to_response('list.html',{'names':names})

   I did three test in this page

   a)  using return HttpResponse("Hello world,My FristDJ1") just display a plain text

   b)  Create html template list.html and copy the template file to /usr...

        (the error message will tell you where the template file you should paste)

   c)  fetch data from Mysql to display data on html.

       I guess the data fetching process should be done in Module. here is doing some testof

 

1.4 Update urls.py

     urlpatterns = patterns('',
                      (r'^hello/$', hello),    

     I encoutered some error in this step,for example:

     didn't keep '' before r'^ in patterns()

     didn't add 'from view import  hello' (it works with out this step in my second example)
