I see this is a common problem and understand the idea is that you cannot add many to many unless it is created first. I have seen multiple solutions for this but unsure which one to use.
Models.py
class Concert(models.Model):
venue = models.CharField(max_length=200, null=True)
concertid = models.CharField(max_length = 200, null=False, default='didnotsaveproperly')
date = models.DateField(null=True)
city = models.CharField(max_length=100, null=True)
country = models.CharField(max_length=200, null=True)
user = models.ManyToManyField(USER_MODEL, related_name="concerts", null=True)
song = models.ManyToManyField("Song", blank=True, null=True)
def __str__(self):
return str(self.concertid) " " str(self.venue) " " str(self.date)
Views.py
def log_concert_and_song(request, concertdict):
if request.method == "POST":
Concert_save = Concert(
concertid=concertdict['id'],
date=concertdict['eventDate'],
venue=concertdict['venue'],
city=concertdict['city'],
country=concertdict['country'],
user = request.user
)
Concert_save.save()
Should I use the User model?
CodePudding user response:
You can add to Many-to-Many relationship by using add

def log_concert_and_song(request, concertdict):
if request.method == "POST":
Concert_save = Concert(
concertid=concertdict['id'],
date=concertdict['eventDate'],
venue=concertdict['venue'],
city=concertdict['city'],
country=concertdict['country'],
)
Concert_save.save()
Concert_save.user.add(request.user)
or as error says:
list_of_users = [request.user,]
Concert_save.user.set([list_of_users])
