Why isn't a django database object created?

Question

I'm trying to create a drink database app in django. I have created a drinkRecipe model with ManyToManyField relation to Ingredients model. I can successfully add Ingredients to database via app UI, but for some reason when creating a drink, I get no errors nor do I add the drink to database, instead of going back to the index page only the URL of current page changes. What am I missing?

models.py:

class DrinkRecipe(models.Model):
drinkName = models.CharField(max_length=100)
ingredients = models.ManyToManyField(Ingredients)
utensil = models.IntegerField(choices=requiredUtensil, default=0)
preparation = models.CharField(max_length=1000)

def __str__(self):
    return self.drinkName

forms.py:

class DrinkForm(forms.Form):
name = forms.CharField(max_length=100, label="Name:")
utensil = forms.ChoiceField(choices=requiredUtensil, label="Required utensil:")
ingredients = forms.ModelChoiceField(queryset=Ingredients.objects.all(), widget=forms.CheckboxSelectMultiple())
preparation = forms.CharField(widget=forms.Textarea)

views.py:

class AddDrinkView(View):

def get(self, request):
    form_drinks = DrinkForm()
    drinks_list = DrinkRecipe.objects.all()
    context = {
        'form_drinks': form_drinks,
        'drinks_list': drinks_list,
    }
    return render(request, 'shakerApp/add_drink.html', context)

def post(self, request):
    form_drinks = DrinkForm(request.POST)

    if form_drinks.is_valid():

        DrinkRecipe.objects.create(
            name=form_drinks.cleaned_data['name'],
            utensil=form_drinks.cleaned_data['utensil'],
            ingredients=form_drinks.cleaned_data['ingredients'],
            preparation=form_drinks.cleaned_data['preparation']
        )
    else:
        messages.error(request, "Drink form is invalid.")

    return HttpResponseRedirect(reverse('shakerApp:index'))

*edited to change brackets per @Bono suggestion

**EDIT: So, I'm a moron and didn't add method='post' to in the template. That solved the part that I stayed in the add_drink view after hitting submit, but, the database still is not updated.

Answer 1

So, there was actually a problem with form. The DrinkRecipe model consists of ManyToManyField, and was not properly used in the corresponding form. Basically, ModelChoiceField couldn't work with widget=forms.CheckboxSelectMultiple(). Thank you to @ThePjot for pointing me in the right direction. Corrected below.

forms.py:

class DrinkForm(forms.Form):
    name = forms.CharField(max_length=100, label="Name:")
    utensil = forms.ChoiceField(choices=requiredUtensil, label="Required utensil:")
    ingredients = forms.ModelMultipleChoiceField(
        queryset=Ingredients.objects.all(),
        widget=forms.CheckboxSelectMultiple()
    )
    preparation = forms.CharField(widget=forms.Textarea)
