[FIXED] After getting a form.cleaned_data from POST how to pass it to another view?

Issue

as the title says: how can I (in DJANGO) get data from a form in a view (in the code below is the ALIMENTA2 view) and then use that as context in another class-based view (GMO, which is a PDF report built with easy_pdf)?

I'm a noob at django, but I've tried redirect and render... I don't seem to understand exactly what I'm doing, really hahaha

views.py

def alimenta2(request):
    if request.method == 'POST':

        form = AlimentaForm(request.POST)

        if form.is_valid():

            day = form.cleaned_data['sign_date']
            shipper = form.cleaned_data['shipper']

            context = {'day': day, 'shipper': shipper}
            #HERE IS THE PROBLEM, I WANT TO PASS THE CONTEXT:
            return redirect('GMO', context=context)

    else: form = AlimentaForm()

    return render(request, 'agroex/alimenta2.html', {'form':form})

class GMO(PDFTemplateView):
    template_name = 'agroex/gmo.html'

    def get_context_data(self, **kwargs):
        context = super(GMO, self).get_context_data(
            pagesize='A4',
            title='NON-GMO Certificate',
            day=self.day,
            **kwargs
        )

urls.py

urlpatterns = [
    path('', views.agroex, name='agroex'),
    path('alimenta2/', views.alimenta2, name='alimenta2'),
    path('alimenta2/GMO/', views.GMO.as_view(), name='GMO'),
]

Solution

You can store the variables in session and then retrieve in the other view, like this:

def alimenta2(request):
    if request.method == 'POST':

        form = AlimentaForm(request.POST)

        if form.is_valid():

            day = form.cleaned_data['sign_date']
            shipper = form.cleaned_data['shipper']

            request.session['day'] = day
            request.session['shipper_id'] = shipper.id

            return redirect('GMO')

        else:
            form = AlimentaForm()
            return render(request, 'agroex/alimenta2.html', {'form':form})

class GMO(PDFTemplateView):
    template_name = 'agroex/gmo.html'

    def get_context_data(self, **kwargs):
        day = request.session['day']
        shipper_id = self.request.session['shipper_id']

        shipper = Shipper.objects.get(id=shipper_id)

        context = super(GMO, self).get_context_data(
                pagesize='A4',
                title='NON-GMO Certificate',
                day=day,
                shipper=shipper,
                **kwargs
       )
