Linking instance of a model with instance of a different model using ModelForm

manpreet Best Answer 3 years ago

I have two models, "Fixture" and "PlayerVotes". The PlayerVotes model has two foreign keys, a link to a particular fixture and the voter (request.user).

I want to display the entire list of fixture as an expandable accordion (bootstrap4) and allow the logged in user to give some votes for each instance of fixture. I am not sure where I could have the form validation and the save() functions.

models.py

class Fixture(models.Model):
    season = models.PositiveIntegerField(blank=False, null=False,
            validators=[
                MinValueValidator(2019),
                MaxValueValidator(datetime.now().year)])
    round = models.PositiveIntegerField(blank=False, null=False)
    game_time = models.DateTimeField(blank=True, null=True)
    opponent = models.ForeignKey(Teams, on_delete=models.SET_NULL, null=True)
    goals_for = models.PositiveIntegerField(null=True)
    goals_againt = models.PositiveIntegerField(null=True)

    def __str__(self):
        return 'Round '+str(self.round)+ ' ('+str(self.season)+ ')'

class PlayerVotes(models.Model):
    voter = models.ForeignKey(User,related_name="voter" ,on_delete=models.SET_NULL, null=True)
    round = models.ForeignKey(Fixture, on_delete=models.SET_NULL, null=True)
    three_votes = models.ForeignKey(User,related_name="three_votes" ,on_delete=models.SET_NULL, null=True)
    two_votes = models.ForeignKey(User,related_name="two_votes" ,on_delete=models.SET_NULL, null=True)
    one_vote = models.ForeignKey(User,related_name="one_vote", on_delete=models
