Django formset empty dict

Using Django Templates & Frontend
1

Hello,

I try to get value from formset, but I get an empty dict…

views.py

class CmsView(ListView):
    queryset = Cmsexport.objects.all().values()
    model = Cmsexport
    form_class = CmsFilterForm
    template_name = 'table.html'
    context_object_name = 'table'
    paginate_by = 10

    def get_queryset(self):
        queryset = super(CmsView, self).get_queryset()
        field = self.request.GET.get('field')
        lookup = self.request.GET.get('lookup')
        value = self.request.GET.get('value')
        reset = self.request.GET.get('btn-reset')

        formset = CmsFormSet(self.request.GET)
        if formset.is_valid():
            for f in formset:
                print(f.cleaned_data)

        if (field and lookup and value) is not None:
            query = field.lower().replace(" ", "_") + '__' + lookup
            queryset = Cmsexport.objects.filter(**{ query: value }).values()

        if reset:
            queryset = Cmsexport.objects.filter().values()

        return queryset

    def get_context_data(self, **kwargs):
        context = super(CmsView, self).get_context_data(**kwargs)
        #context['form'] = CmsFilterForm()
        context['formset'] = CmsFormSet(queryset=Cmsexport.objects.none())
        return context

forms.py

from django import forms
from django.forms import ModelForm, modelformset_factory
from .models import (
    Cmsexport,
    Dns,
    Alias,
    Sectools,
)

class CmsFilterForm(ModelForm):
    class Meta:
        model = Cmsexport
        fields = '__all__'

CmsFormSet = modelformset_factory(
    Cmsexport, 
    fields='__all__',
    extra=2,
    can_delete=True,
)

template.py

{% block content %}

          <table>
          {% for form in formset %}
          <div class="table-form">
          <label for="Field">Field </label>
          <select name="field" class="form-control">
          {% for field in form %}
              <option value="{{field.label}}">{{field.label}}</option>
          {% endfor %}
          </select>
          <label for="lookup">Lookup </label>
          <select name="lookup" class="form-control">
              <option value="iexact">iexact</option>

              <option value="in">in</option>
          </select>
          <label for="value">Value </label>
          <input id="value" type="text" name="value" value="{{ current_value }}">
          </div>
          {% endfor %}
          </table>
          <button id="add-form" type="button" class="btn btn-primary">Add form</button>
          <button type="submit" class="btn btn-primary">Search</button>
          <button type="submit" name="btn-reset" class="btn btn-secondary" value="btn-reset">Reset</button>
        </form>
      </div>
    </div>
  </div>
</div>

output:

You’re fighting against Django by trying to manually render elements individually. The name attributes that you are assigning to the input elements do not match what Django is going to expect for those fields.

For the purposes of getting your view working, I suggest you render:

Then, adjustments that need to be made to the contents of the form should be made in the view, not the templates.
