Hi Django Community!!!
I’ve been working with Django for a short time and I come to you to solve a little problem I have.
I have a “RecipeRequirement” model, which looks like this:
class RecipeRequirement(models.Model):
menu_item = models.ForeignKey(MenuItem, on_delete=models.CASCADE)
ingredient = models.ForeignKey(Ingredient, on_delete=models.CASCADE)
quantity = models.FloatField(default=0.0)
def __str__(self):
return f'#{self.id}'
def clean(self):
if self.quantity < 0:
raise ValidationError('You cannot have a recipe requirement with a quantity less than zero.')
class Meta:
verbose_name = 'Recipe Requirement'
verbose_name_plural = 'Recipe Requirements'
As you can see, two of the fields of the model are of type “ForeignKey” and refer to the “Ingredient” and “MenuItem” models.
In the Django admin panel, I want to add two filters for this template: one with the “ingredient” field and another with the “menu_item” field. For this, I have created the “RecipeRequirementAdmin” class:
class RecipeRequirementAdmin(admin.ModelAdmin):
list_display = ['__str__', 'ingredient', 'menu_item']
list_filter = [
('ingredient', admin.RelatedOnlyFieldListFilter),
('menu_item', admin.RelatedOnlyFieldListFilter),
]
Well, as you can see in the screenshot below, the filters with the records of the “Ingredient” model appear without problem, but the filters of the “MenuItem” model do not:
Could someone help me to find the reason why this is happening?
In advance, I appreciate the time you can dedicate to this problem and the help you can give me.
P.S.: To clarify, that I have another model “Purchase” that also has a field of the type “ForeignKey” making reference to the model “MenuItem”. Could this have some kind of relation with the problem?
