I'm trying to modify an existing row of my database, it's a from an intermediary table named "CharacterSkill" with an unique together constraint :
models.py
class CharacterSkill(models.Model):
character = models.ForeignKey(Character, on_delete=models.CASCADE)
level = models.IntegerField(default=0)
skill = models.ForeignKey(Skill, on_delete=models.CASCADE)
class Meta:
unique_together = ("character","skill")
I did a form to change the level but I'm unable to save the form, I have two errors messages from both fields "character" & "skill":
Select a valid choice. That choice is not one of the available choices.
Can you help on that please ? :)
My form :
class SkillCreateForm(forms.ModelForm):
class Meta:
model = CharacterSkill
fields = ('skill','level','character',)
my view :
def skill_update(request,skillpk,instancepk):
form = SkillCreateForm(request.POST)
user = User.objects.get (id = request.user.id)
instance = Character.objects.get (id = instancepk)
skill = CharacterSkill.objects.get(id = skillpk)
data = {'character' : instance,
'skill' : skill.skill,
'level' : skill.level,
}
if form.is_valid():
form.save()
return redirect('persomaker:skill_list', instance.id)
else:
form = SkillCreateForm(data)
#form.fields['skill'].widget = HiddenInput()
#form.fields['character'].widget = HiddenInput()
return render(request, 'character/create_skill.html',
{'instance':instance,
'skill':skill,
'form': form,})
based on a book, I changed the way I bounded the form to use instance :
def skill_update(request,skillpk,instancepk):
user = User.objects.get (id = request.user.id)
instance = Character.objects.get (id = instancepk)
skill = CharacterSkill.objects.get(id = skillpk)
if request.method == "POST":
form = SkillModifyForm(request.POST,instance = skill,)
print (skill)
if form.is_valid():
form.save()
return redirect('persomaker:skill_list', instance.id)
else:
form = SkillModifyForm(instance = skill,)
return render(request, 'character/create_skill.html',
{'instance':instance,
'skill':skill,
'form': form,})
