Problem to save data from a form to the session

I am trying to save the data from a form to the session but it seems that it's not the right datatype.

I have tried model_to_dict and cleaned as it is working fine for my other form that takes similar data in entry but it didn't work.

class ActivitiesForm(forms.Form):
    activity = forms.ModelChoiceField(label='Select your activities', queryset=Activity.objects.all())
    target_group = forms.ChoiceField(label='Who is the report destined to?', choices=OutputOutcomeImpact.TARGETGROUP)


class Activities(TemplateView):
    template_name = 'blog/activities.html'
    context = {'title': 'Activities selection page'}
    def get(self, request):
        form_act = ActivitiesForm()
        form_act.fields['activity'].queryset = Activity.objects.filter(categories__sectors__name=request.session['sector']['name'])
        self.context['form_act']=form_act
        return render(request,self.template_name, self.context)
    def post(self,request):
        form_act = ActivitiesForm(request.POST)
        if form_act.is_valid():
            print(form_act.is_valid(),form_act.cleaned_data['activity'],type(form_act.cleaned_data['activity']),type(model_to_dict(form_act.cleaned_data['activity'])),form_act['activity'])
            request.session['activity'] = model_to_dict(form_act.cleaned_data['activity'])
            request.session['target_group'] = model_to_dict(form_act.cleaned_data['target_group'])
            return redirect('/about', self.context)

Here's the type of data that I get from the print and the error:

True Municipal waste incineration <class 'blog.models.Activity'> <class 'dict'> <select name="activity" required id="id_activity">
  <option value="">---------</option>

  <option value="Municipal waste incineration" selected>Municipal waste incineration</option>

  <option value="Plastic upcycling">Plastic upcycling</option>

</select>
Internal Server Error: /activities/
.
.
.
AttributeError: 'str' object has no attribute '_meta'

Hope it helps. Thanks.

Probably the problem is with target_group. Its value should be string because it is coming from ChoiceField. So you don't need to use model_to_dict for that.

request.session['target_group'] = form_act.cleaned_data['target_group']
