Creating few models with one submit depending on the selected items from multiselect? - dmytruk - Mar-18-2019 A'm beginner at Django. Sry for my bad english. I'm ukrainian) There are 2 models: 1. RelationType ; 2. RequestRelation . The second model is connected with the first through MTM field .There is a multiple select form based on a list of “relationship types”. Need to create few models of when RequestRelation submitting, depending on the selected items of the multi-select ?F.e., *if "husband / wife / son" is chosen, need to create 3 models accordingly*. Distinctive in them are only the types of relationships. The form.is_valid() , the correct values come.But so far, only one model is created, with lists of all selected relationship types. Also in my code there is a bug. The model is created immediately when the page is loaded, not when it is submitted. Thank you in advance. models.py class RelationType(models.Model): title = models.CharField(max_length=40) def __unicode__(self): return self.title class RelationRequest(models.Model): creator = models.ForeignKey(User, related_name='creator') relation = models.ForeignKey(User, related_name='relation') type_of_relation = models.ManyToManyField(RelationType, related_name='type_relation', verbose_name=_('type_relation')) status = models.BooleanField(_('status'), default=False) created = models.DateTimeField(_('created'), auto_now_add=True) updated = models.DateTimeField(_('updated'), auto_now=True)html <form action="" method="POST" multiple="multiple"> {% csrf_token %} {{ relation_form.type_of_relation }} <input type='submit' value='ok'> </form>forms.py class RelationRequestForm(forms.ModelForm): class Meta: model = RelationRequest fields = ('type_of_relation',) widgets = { 'type_of_relation': forms.SelectMultiple( attrs={ 'class': 'select2', 'style': 'width: 235px', } ), } def __init__(self, *args, **kwargs): super(RelationRequestForm, self).__init__(*args, **kwargs) self.fields['type_of_relation'].empty_label = None self.fields['type_of_relation'] = forms.ModelMultipleChoiceField(queryset=RelationType.objects.all()) def clean(self): type_of_relation = self.cleaned_data.get('type_of_relation')views.py def post(self, request, *args, **kwargs): self.object = self.get_object() relation_form = RelationRequestForm(request.POST) if relation_form.is_valid(): req_rel = relation_form.save(commit=False) req_rel.creator = request.user relation_user_id = int(filter(lambda x: x.isdigit(), request.path)) req_rel.relation = User.objects.get(id = relation_user_id) req_rel.save() relation_form.save_m2m() context = self.get_context_data(relation_form = relation_form) return self.render_to_response(context) |
