Django inlineformset will not submit - django

Question

My application has two models, Recipe and RecipeIngredient, related by foreign key. Each Recipe may have many different RecipeIngredients (and different number of associated ingredients for each recipe). So using a dynamic formset to assign ingredients to a recipe seems to be the best approach.
I have a simple form that has a user enter a quantity and select a unit and ingredient from a dropdown. As a standalone form it works fine.
Unfortunately, I cannot get any formset incorporating it to submit.
I have searched many of the different formset Q&As here on StackOverflow but cannot see where the problem is. When I click 'submit', the form blinks and refreshes in place, with the entered values still in the form. No objects are created. No errors report to the console nor to the browser. The related code:
The models:
class RecipeBase(models.Model):
id = models.UUIDField(primary_key=True,default=uuid.uuid4,null=False)
name = models.CharField(max_length=128,null=False)
creation_date = models.DateField("Record creation date",auto_now_add=True)
creation_user = models.CharField("Record creation user",max_length=150)
lastupdated_date = models.DateField(auto_now=True)
lastupdated_user = models.CharField(max_length=150)
category = models.ForeignKey(RecipeCategory,on_delete=models.CASCADE,related_name='recipes')
subcategory = models.ForeignKey(RecipeSubcategory,on_delete=models.CASCADE,related_name='recipes')
def __str__(self):
return str(self.name)
class RecipeIngredient(models.Model):
id = models.UUIDField(primary_key=True,default=uuid.uuid4,null=False)
quantity = models.DecimalField(max_digits=8,decimal_places=3,null=False)
referenced_unit = models.ForeignKey(UnitDetail,on_delete=models.CASCADE)
referenced_ingredient = models.ForeignKey(Ingredient,on_delete=models.CASCADE)
parent_recipe = models.ForeignKey(RecipeBase,on_delete=models.CASCADE,related_name='ingredients')
def __str__(self):
return str(self.id)[:8]
The call to enter ingredients:
<a class='btn btn-success' href="{% url 'recipes:addingredient' pk=recipe_details.pk %}">Add Ingredients</a>
Calls the view:
class AddIngredientView(CreateView):
form_class = AddIngredientForm
model = RecipeIngredient
template_name = 'addingredientmultiple2.html'
success_url = "recipes:listrecipes"
def get_context_data(self, **kwargs):
parent_recipe_id = RecipeBase.objects.get(id=self.kwargs['pk'])
data = super(AddIngredientView, self).get_context_data(**kwargs)
if self.request.POST:
data['ingredients'] = AddIngredientFormset(self.request.POST)
data['parent_recipe_id'] = parent_recipe_id
else:
data['ingredients'] = AddIngredientFormset()
data['fixture'] = parent_recipe_id
return data
def form_valid(self, form, **kwargs):
user = self.request.user
fixture = RecipeBase.objects.get(id=self.kwargs['pk'])
context = self.get_context_data()
formset = AddIngredientFormset(self.request.POST)
if formset.is_valid():
ingredients = formset.save()
for recipeingredient in ingredients:
#recipeingredient.creation_user = str(request.user)
#recipeingredient.lastupdated_user = str(request.user)
recipeingredient.parent_recipe_id = parent_recipe_id
#recipeingredient.user = user
recipeingredient.save()
return super(AddIngredientView, self).form_valid(form)
Using form and formset:
class AddIngredientForm(forms.ModelForm):
quantity = forms.DecimalField(widget=forms.NumberInput(attrs={'data-placeholder': 0.00,'size': '8','label_tag': ''}))
referenced_unit = forms.ModelChoiceField(queryset=UnitDetail.objects.all())
referenced_ingredient = forms.ModelChoiceField(queryset=Ingredient.objects.all())
class Meta():
model = RecipeIngredient
fields = ('quantity','referenced_unit','referenced_ingredient',)
AddIngredientFormset = inlineformset_factory(RecipeBase,RecipeIngredient,form=AddIngredientForm,extra=1,can_delete=True)
And template:
{{ ingredients.media.css }}
<div class="container">
<h2>Add ingredients to {{ referring_recipe_name }}</h2>
<h4>{{ referring_recipe_id }}</h4>
</div>
<div class="col-md-4">
<form class="form-horizontal" enctype="multipart/form-data" method="post">{% csrf_token %}
<table class="table">
{{ ingredients.management_form }}
{% for form in ingredients.forms %}
{% if forloop.first %}
<thead>
<tr>
{% for field in form.visible_fields %}
<th>{{ field.label|capfirst }}</th>
{% endfor %}
</tr>
</thead>
{% endif %}
<tr class="formset_row">
{% for field in form.visible_fields %}
<td>
{# Include the hidden fields in the form #}
{% if forloop.first %}
{% for hidden in form.hidden_fields %}
{{ hidden }}
{% endfor %}
{% endif %}
{{ field.errors.as_ul }}
{{ field }}
</td>
{% endfor %}
</tr>
{% endfor %}
</table>
<input class='btn btn-success' type="submit" value="Save"/> back to the list
</form>
