Hello
I need to use a model form to create a new instance of Recette, using
multiple choices list instead of the foreign_key
/class Recette(models.Model)://
// ......//
// categoriederecette = models.ForeignKey(Categorie,
on_delete=models.CASCADE) //
/
/class Categorie(models.Model)://
// SOUPE = 'SP'//
// DESSERTS ='DS'//
// PLATUNIQUE ='PU'//
// LISTE_CHOIX = ((SOUPE,'Soupe'), (DESSERTS,'Desserts'),
(PLATUNIQUE,'Plat unique'),)//
// .....//
// categorierecette = models.CharField(db_column='Categorierecette',
max_length=15, choices=LISTE_CHOIX, blank=True, null=True) # Field name
made lowercase..../
I use a Modelform/:
/
/class RecettesForm(forms.ModelForm)://
// categoriederecette = forms.ChoiceField(choices =
Categorie.LISTE_CHOIX)//
////
// class Meta://
// model = Recette//
// fields = (......//,'categoriederecette')/
/
/
The form is displayed correctly, but cannot be saved. In the test /if
form.is_valid():/ I get a value error -
/ValueError: Cannot assign "'SP'": "Recette.categoriederecette" must be
a "Categorie" instance./
Any help would be greatly appreciated.
