I am building a user profile in django, where I want the user to enter his skill set. The skill field is a ManyToMany field to a model name Skills. Below is shown the models.py file
class UserProfile(models.Model):
name = models.CharField(max_length = 300, null = True, blank=True)
location = models.CharField(max_length=500, null=True, blank=True)
birthday = models.DateField(null = True, blank = True)
user = models.ForeignKey(User, unique=True)
skills = models.ManyToManyField(Skill, blank=True, null=True)
class Skill(models.Model):
name = models.CharField(max_length=50)
def __unicode__(self):
return u'%s' %(self.name)
As you can see all the fields are set null=True. This is because I am keeping the fields empty and want the user to input them as and when he/she wants to. So I am updating all these fields using AJAX call. I have managed to edit all the other fields, but I do not know how can I edit a M2M field
I can get a list of all the skills linked to a profile using profile.skills.all() but I do not know how to update this list. I basically want to add or remove skill objects from this list. I think there is something in the django.db.models.fields.related.ManyRelatedManager using which I can edit the field
Any help is really appreciated. I have not found anything at all on this subject. There is some information about editing this field using a ModelForm but nothing about editing the individual field.
To edit the m2m intermediary table, use the add and remove methods on the ManyRelatedManager.
It's true, the hardest things to google on the django docs are manytomanyfield and other continuous strings. I've blogged about formfield_for_manytomany solely to appear in search results for myself.
