I'm building an app where I can add recipes and add ingredients to those recipes. On view recipe_details I have a button to add_new_ingredient. When I'm on new_ingredient_form I want to have back button to get back to the details of recipe. I'm trying to pass recipe's pk but it doesn't work. How am I able to pass recipe's pk to be able to back to previous view?
models.py
class Recipe(Timestamp):
id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False, unique=True)
title = models.CharField(max_length=100, unique=True)
preparation = models.TextField()
def __str__(self):
return self.title
class Ingredient(Timestamp):
id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False, unique=True)
recipe = models.ForeignKey(Recipe, on_delete=models.CASCADE)
name = models.CharField(max_length=100)
amount = models.PositiveSmallIntegerField(blank=True, null=True)
unit = models.ForeignKey('Unit', on_delete=models.SET_NULL, blank=True, null=True)
def __str__(self):
return self.name
views.py
class RecipeView(generic.DetailView):
model = Recipe
context_object_name = 'recipe'
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['ingredients_list'] = Ingredient.objects.filter(recipe=self.object.pk)
return context
class AddIngredientView(generic.edit.CreateView):
model = Ingredient
fields = [
'name',
'amount',
'unit'
]
success_url = '/'
template_name = 'recipes/add_ingredient.html'
def dispatch(self, request, *args, **kwargs):
self.recipe = get_object_or_404(Recipe, pk=self.kwargs['pk'])
return super().dispatch(request, *args, **kwargs)
def form_valid(self, form):
form.instance.recipe = self.recipe
return super().form_valid(form)
def get_success_url(self):
if 'add_another' in self.request.POST:
url = reverse_lazy('recipes:add_ingredient', kwargs={'pk': self.object.recipe_id})
else:
url = reverse_lazy('recipes:recipe', kwargs={'pk': self.object.recipe_id})
return url
