Allow users to vote up, down or nothing

[Robin Lery]

Hello,

I have made an app to create article. This is the model:

class Article(models.Model):
    user = models.ForeignKey(settings.AUTH_USER_MODEL)
    title = models.CharField(max_length=150)
    body = models.TextField()
    pub_date = models.DateTimeField(default=timezone.now)
    tags = models.ManyToManyField(Tag)
    article_image = models.ImageField(upload_to=get_upload_file_name, blank=True)

Here I want to setup a voting system for each app. There I would the user to vote up, or vote down, or do nothing. Boolean field would have been great, but since an article can have 3 choices of votes  (vote up / vote down / no vote ), how should I go about doing this? Your help and guidance will be very much appreciated.

Thank you.

Maybe a nullable boolean field

I will assume user can vote a specific article. I would go for another model, like that

class VoteForArticle(models.Model):

    DOWN = 0

    NEUTRAL = 1

    UP = 2

    VOTES = ((DOWN, "down"), (NEUTRAL, "neutral)", (UP, "up"))

    user = models.ForeignKey(settings.AUTH_USER_MODEL)

    article = models.ForeignKey("Article")

    vote = models.IntegerField(choices=VOTES)

If you are concerned with space, use a models.CharField with max_length = 1
