### Quick start

#### Install `django-vote` by pip

```shell
pip install django-vote
```

#### Add `'vote'` to your `INSTALLED_APPS` setting like this

```python
INSTALLED_APPS = (
  ...
  'vote',
)
```

#### Add `VoteModel` to the model you want to vote

```python
from vote.models import VoteModel

class ArticleReview(VoteModel, models.Model):
    ...
```

#### Run migrate

```shell
manage.py makemigrations
manage.py migrate
```

### Use vote API

```python
review = ArticleReview.objects.get(pk=1)

# Up vote to the object
review.votes.up(user_id)

# Down vote to the object
review.votes.down(user_id)

# Removes a vote from the object
review.votes.delete(user_id)

# Check if the user already voted (up) the object
review.votes.exists(user_id)

# Check if the user already voted (down) the object
# import UP, DOWN from vote.models
review.votes.exists(user_id, action=DOWN)

# Returns the number of votes for the object
review.votes.count()

# Returns the number of down votes for the object
review.votes.count(action=DOWN)

# Returns a list of users who voted and their voting date
review.votes.user_ids()


# Returns all instances voted by user
Review.votes.all(user_id)

```

### Use template tags

There are two template tags you can use in template: 
1. `vote_count` to get vote count for a model instance
2. `vote_exists` to check whether current user vote for the instance

``` html
{% load vote %}
<ol>
    {% for comment in comments %}
    <li>
        {{comment.content}} - up:{% vote_count comment "up" %} - down: {% vote_count comment "down" %} - exists_up:
        {% vote_exists comment user "up" %} - exists_down: {% vote_exists comment user "down"%}
    </li>
    {% endfor %}
</ol>
```

### Use `VoteMixin` for REST API

Install [django-rest-framework](https://github.com/encode/django-rest-framework/)

``` python
from rest_framework.viewsets import ModelViewSet
from vote.views import VoteMixin

class CommentViewSet(ModelViewSet, VoteMixin):
    queryset = Comment.objects.all()
    serializer_class = CommentSerializer
```

```sh
POST /api/comments/{id}/vote/
POST /api/comments/{id}/vote/ {"action":"down"}
DELETE /api/comments/{id}/vote/
```
