How to save multiple model form in one template?

[Django Lover]

I have one page, which I have to show three model form and three different submit button for each.

My question is how I can save these three form individually?

FOLLOWING IS CODE:-

**form.py**

class UserTaxesMultiForm(MultiModelForm):

   form_classes = {

       'user_tax_form': MyForm,

       'user_discount_form': DiscountForm,

       'user_shiping_form': ShipmentForm,

   }

Note- myForm, DiscountForm, ShipmentForm are model forms. like following-

class MyForm(forms.ModelForm):

       prefix = 'tax'

       class Meta:

           model = StUserTaxDetails

           fields = ('tax_name', 'tax_rate')

     

       tax_name = forms.CharField(max_length=10,

        widget=forms.TextInput(),

        required=True, label="tax name")

        tax_rate = forms.FloatField(required=True,  label="tax rate")

        error_messages  = {

           'required': _('fields are required.'),

       }

        def clean_title(self):

           return self.cleaned_data['tax_name']

        def clean(self):

           tax_name = self.cleaned_data.get('tax_name')

           tax_rate = self.cleaned_data.get('tax_rate')

       

            if not tax_name and not tax_rate:

               raise forms.ValidationError(

                   self.error_messages['required'],

                   code='required',

               )

           return self.cleaned_data

**view.py**

class AddTaxView(LoginRequiredMixin, CreateView):

   template_name = 'invoices/add_tax.html'

   form_class = UserTaxesMultiForm

   success_url = '/add/tax/'

   {WHAT IS THE CODE HERE FOR THE POST METHOD TO SAVE DATA ACORDING DIFFRENT FORM SUBMIT}

               

**HTML**

<form method="POST">

{% form.user_tax_form%}

<input type="submit" value="Submit" />

</form>

<form method="POST">

{% form.user_discount_form%}

<input type="submit" value="Submit" />

</form>

<form method="POST">

{% form.user_shiping_form%}

<input type="submit" value="Submit" />

</form>

I think it would be easier to write out a custom form (without using your model classes, just the fields that you will need for all the models) and then in the save method for that form's view, you create model objects using the fields in the POST request.

[Anthony Petrillo]

Here is an example. I've cut out some of the code, but I this will give you the general idea. Note, I move the data from the Day form in to the Classes table. But you could just save both sets of data to their respective tables if desired.

in views.py

class ClassesAddView(LoginRequiredMixin,View):
    classesFormClass = ClassesRegForm
    daysFormClass = DaysForm
    template_name = 'qing/classes.html'

    def get(self,request,role='NoRole'):
        classesForm = self.classesFormClass()
        context['form'] = classesForm
        daysForm = self.daysFormClass()
        context['daysform'] = daysForm
        return render(request,self.template_name, context)

    def post(self, request, *args, **kwargs):
        classesForm = self.classesFormClass(request.POST)
        daysForm = self.daysFormClass(request.POST)
        if classesForm.is_valid() and daysForm.is_valid():
            days = str(request.POST.getlist('days'))
            reference = request.POST['reference']
            classes = classesForm.save()
            classes = Classes.objects.get(reference=reference)
            classes.days = days
            classes.save()
        else:
            classesForm = self.classesFormClass(request.POST)
            context['form'] = classesForm
            daysForm = self.daysFormClass(request.POST)
            context['daysform'] = daysForm
            context['datavalid'] = False
            return render(request, self.template_name, context)
        return HttpResponseRedirect(reverse('classesadd',args=(role,)))
    
in forms.py

class ClassesForm(ModelForm):
    class Meta:
        model = Classes
        fields = ['reference','course','teachers',etc...]

class DaysForm(forms.Form):
    OPTIONS = (
        ("Sunday", "Sunday"),
        ("Monday", "Monday"),
        ("Tuesday", "Tuesday"),
        ("Wednesday", "Wednesday"),
        ("Thursday", "Thursday"),
        ("Friday", "Friday"),
        ("Saturday", "Saturday"),
        )
    days = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple,
                                         choices=OPTIONS)

First Create 3 Views For each form .

Second Create urls for all 3 views .

THiRD CHANGE ACTION URL ACCORDING TO VIEWS URL

ADD AJAX TO SUBMIT THE FORM 

IF YOU WANT TO DISPLAY A TOAST MESSAGE USE TOASTR ON HTML PAGE.

eg :

 <form action="/YOURFIRSTFORMURL" method="post" id="target">
      {% csrf_token %}
    <div class="form-group">
      <label for="fname">First Name:</label>
      <input type="text" class="form-control" id="fname" placeholder="First Name" name="fname">
    </div>
    <div class="form-group">
      <label for="lname">Last Name:</label>
      <input type="text" class="form-control" id="lname" placeholder="Last Name" name="lname">
    </div>

      <div class="form-group">
      <label for="lname">Gender:</label>
      <input type="text" class="form-control" id="gender" placeholder="Last Name" name="gender">
    </div>
    <button type="submit" class="btn btn-default">Submit</button>
  </form>

</div>



<script>
$( "#target" ).submit(function( event ) {
  var form = $("form").serialize();
  $.ajax({
        url: '',
        data: form ,
        success: function (data) {
        toastr["success"]("New Student Added !")
        }
      });
  event.preventDefault();
});
</script>

VIEWS.PY

def update(request):
    fname =  request.GET.get('fname')
    lname =  request.GET.get('lname')
    gender = request.GET.get('gender')
    student.objects.create(firstname=fname,lastname=lname,gender=gender)

Hi,

I made it more simple and I implemented this also This is a solution is a little different from other solution 

you have three model form, one view which is rendering all the form.

If this is the case or somewhat similar then.

simply give name attribute to each submit button 

like: <button name="firstFrom" type="submit">

and in the view.

 if request.POST:

or if you are using class-based views then inpost func.

simply check for 

 if 'firstForm' in request.POST:

you get the idea I think. This will help you recognize which submit button is hit.

Regards 

Dev

Could you kindly stop spamming your course details over over this discussion group. It's not useful to the majority of us English speaking people.
