Django Tips #1:How to redirect comment post

Entry published on November 20th, 2008 and part of categories django and tag with tips

Django contrib comment is general comment app, so basically you can use it for any Django models. It is so easy to add comment feature to your app. Follow these steps and you'll have comment running on your website

Install the comments framework by adding 'django.contrib.comments' to INSTALLED_APPS.
Run manage.py syncdb so that Django will create the comment tables.

Add the comment app's URLs to your project's urls.py

urlpatterns = patterns('',
    ...
    (r'^comments/', include('django.contrib.comments.urls')),
    ...
)

And in your templates, load comment template tags
```
...
{% load comments %}
...
```

Just say you have post object, and want to add comment form, just put this code:

...
<form action="{% comment_form_target %}" method="POST">
    {{ form }}
    <p class="submit">
    <input type="submit" name="submit" value="Submit">

Django Tutorial : Sphinxsearch and django-sphinx Part 2

Entry published on November 20th, 2008 and part of categories django and tag with django-sphinx , sphinx

Now, we are going to use sphinxsearch and integrate with our django models. For this tutorial, we will build library application, then we implement the book searching system using sphinxsearch.

Let's start, first we create django project.

$django-admin.py startproject sphinxlibrary
$cd sphinxlibrary

Now we create django app called 'library'.

$chmod +x manage.py
$./manage.py startapp library

We build simple model for our books.

from django.db import models

class Book(models.Model):
    
    title = models.CharField(max_length=255)
    isbn = models.CharField(max_length=10)
    summary = models.TextField()
    author = models.CharField(max_length=50)
    link = models.URLField(verify_exists=False)
    
    def __unicode__(self):
        return self.title

Before running manage.py syncdb, this is our settings.py for our tutorial. Make sure you have created database called 'sphinxlibrary' in your MySQL server.

import os
ROOT_PATH = os.path.dirname(__file__)
DEBUG = True
TEMPLATE_DEBUG = DEBUG
DATABASE_ENGINE = 'mysql'
DATABASE_NAME = 'sphinxlibrary'
DATABASE_USER = 'root'
DATABASE_PASSWORD = 'root'
DATABASE_HOST ...

But, there is mysql full text search, see model search What's wrong with it? Nothing is wrong, just

It's only for MySQL
It didn't provide ranking search result
It lack of stemming

So, what is your recommendation then? Well, for this time I use sphinxsearch and django-sphinx.

Installing sphinxsearch

$wget http://sphinxsearch.com/downloads/sphinx-0.9.8.1.tar.gz

Open your terminal, extract and install sphinx
```
$tar -xvf sphinx-0.9.8.1.tar.gz
