qhonuskan-votes 0.2

Easy to use reddit like voting system for django models.

Easy to use reddit like voting system for django models.

Features

• Does not use GenericForeignKeys (which irritates me when making queries) Has vote_buttons_for templatetag, that generates html code for your object for vote buttons.

• Has, default_buttons.css which gives a shape your buttons as default, but you can override.

• Has, voting_script template tag, it generates javascript code to make ajax requests for voting. Automatically finds qhonuskan_votes views.

• voting_script tag also renders overridable show_not_authenticated_error function, so you can use your own error windows (jquery-ui etc.) via overriding it.

• Default buttons are pure css, there is no images. So it’s lite.

What’s new?

• Lettuce tests are added for testing voting system.

• Changed vote view name as qhonuskan_vote. Prefix is required for minimizing view name conflicts.

Quick Implementation Guide

1. Add qhonuskan_votes to your INSTALLED_APPS.

   INSTALLED_APPS = ('...',
                     '...',
                     'qhonuskan_votes')

2. Add VotesField, and add ObjectsWithScoresManager to your model.

   from django.db import models
   from qhonuskan_votes.models import VotesField
   
   class MyModel(models.Model):
       votes = VotesField()
       # Add objects before all other managers to avoid issues mention in http://stackoverflow.com/a/4455374/1462141
       objects = models.Manager()
   
       #For just a list of objects that are not ordered that can be customized.
       objects_with_scores = ObjectsWithScoresManager()
   
       #For a objects ordered by score.
       sort_by_score = SortByScoresManager()
       ...
       ...

3. Syncdb.

4. Extend your urls [1].

   import qhonuskan_votes.urls
   from django.conf.urls.defaults import *
   
   urlpatterns = patterns('',
     ...
     ...
     url(r'^votes/', include(qhonuskan_votes.urls)),
   )

5. Create the list in you view. Use

   #For a regular list of items without votes from your model use the following:
   item_list_no_score = Items.objects.all()
   
   #For a list with scores that can be customized with use the following:
   item_list_unordered_with_scores = Items.objects_with_scores.all()
   #to customize the order by a field unique to your model. So something like this:
   item_list_unordered_with_scores = Items.objects_with_scores.all().order_by(-date_created)
   
   #To obtain a list of items sorted by vote counts like (1,0,-1) like Reddit:
   item_list_ordered__scores = Items.sort_by_score.all()

6. Load qhonuskan_votes templatetags from your template. You will need STATIC_PREFIX too.

   {% load qhonuskan_votes static %}
   {% get_static_prefix as STATIC_PREFIX %}

7. Load default_buttons.css to give little shape to buttons

   <link href="{{STATIC_PREFIX}}default_buttons.css" rel="stylesheet" type="text/css" />

8. After that line, if you wish you can override some properties

   <style type="text/css">
     div.vote_buttons {
       width: 40px;
       margin-right: 5px;
       float: left;
       border: 1px solid #666;
     }
   </style>

9. Load jquery to your template

   <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>

10. After all, you can add voting_script template tag to your head section. It generates necessary javascript code for ajax requests.

{% voting_script %}

11. use vote_buttons_for_object template tag to create buttons.

    {% for object in objects %}
      <div class="object">
        {% vote_buttons_for object %}
          <div class="text">
            {{ object.text }}
          </div>
      </div>
    {% endfor %}
