hello,
i'm struggling with ManyToMany fields (Rajesh helped me a lot;) and
have another question. My model Article, has ManyToMany relation with
Video model (for storing only youtube videos).
class Article(models.Model):
video = models.ManyToManyField(Video, blank=True, null=True)
class Video(models.Model):
url = models.CharField(max_length=300)
name = models.CharField(max_length=300)
Then i add 3 videos to an Article. Since not all articles have videos,
i want to filter out those that have it.
Filter looks like this:
Article.objects.filter(video__isnull=False)
So here is the problem.. let's say i have 5 articles in my DB and only
one has 3 videos.. this filter doesn't return an article that has
videos, but rather returns 3x the same article name.. probably,
because of 3 added videos to it.
so my question here is: is this the right way to check, if article has
videos (Article.objects.filter(video__isnull=False))? if this the
right way, what is (should i add costum method in my model)?
I would appreciate any help,
Martin
