Unable to savedata to database in Django using Model and Forms

Question

I trying to to create a database panel for a restaurant app where a user can add, remove, view and create a menu for the restaurant. In this the user can add the name, cuisine, category(veg/non veg) and cost as details of the menu item.

Here is my Models.py:

class Cuisine(models.Model):
    cuisine = models.CharField(max_length=15)

    def __str__(self):
        return self.cuisine

    class Meta:
        verbose_name_plural = 'cuisines'


class Category(models.Model):
    category_type = models.CharField(max_length=9)

    def __str__(self):
        return self.category_type

    class Meta:
        verbose_name_plural = 'category type'


class Item(models.Model):
    name = models.CharField(max_length=50)
    cost = models.IntegerField()
    cuisine = models.ForeignKey(Cuisine, on_delete=models.CASCADE)
    category = models.ForeignKey(Category, on_delete=models.CASCADE)

    def __str__(self):
        return self.name

Here is Forms.py:

class ItemForm(forms.ModelForm):
    class Meta:
        model = Item
        fields = ['name', 'cost']


class CategoryForm(forms.ModelForm):
    class Meta:
        model = Category
        fields = ['category_type']


class CuisineForm(forms.ModelForm):
    class Meta:
        model = Cuisine
        fields = ['cuisine']

And below is my Views.py:

@login_required()
def add_item(request):
    if request.method == 'POST':
        itemform = ItemForm(request.POST or None)
        catform = CategoryForm(request.POST or None)
        cuisineform = CuisineForm(request.POST or None)
        if itemform.is_valid():
            item = itemform.save(commit=False)
            ct = catform.save(commit=False)
            cui = cuisineform.save(commit=False)
            item.name = request.POST.get('name')
            cui.cuisine = request.POST.get('cuisine')
            ct.category = request.POST.get('category_type')
            item.cost = request.POST.get('cost')
            item.save()
            ct.save()
            cui.save()
            messages.success(request, 'Item added successfully!!')
        else:
            messages.warning(request, 'Unable to add the item.')
        return redirect('add_item')

    else:
        item_list = ItemList.objects.all()
        category = Category.objects.all()
        cuisine = Cuisine.objects.all()
        context = {
            'items': item_list,
            'category': category,
            'cuisine': cuisine
        }
        return render(request, 'add_item.html', context)

I am able to add add the menu item from the django admin panel but i am having a error while saving the data to database from the user side as i want to give user the authority to add the item. I am not able to save the form using .save() option.
I know the error is in my forms.py but i don't know what as i am new to Django. I am attaching the screenshot of the error as well as of my frontend page from where i am adding the data.

Here's the error :

Here's the frontend page :

Please note that i want to use Cuisine and Category as the dropdown list from the database.

Answer 1

Actually you are trying to set...

ct.category = request.POST.get('category')

And as per your code ct assigned from catform.save(commit=False).

catform assigned from CategoryForm(request.POST or None)

And CategoryForm has model class Category, but Category model has no any attribute like category which is you are trying to set by as per below line...

ct.category = request.POST.get('category')

So, the form will be invalid and you can not save invalid form. Thus, your error came.
