Creé un formulario donde los usuarios ingresarán un rango de fechas. Una vez enviado, debe devolver una lista de mi base de datos de personas cuyos cumpleaños están dentro de ese rango de fechas. Soy bastante nuevo en Django y lo he intentado pero no entiendo cómo pasar mi "start_date & end_date" como kwargs de mi formulario a ListView.
vistas.py:
class BirthdaysRangeFormView(FormView): template_name = 'snippets/date_selection_form.html' form_class = datefilterform def get_form_kwargs(self): kwargs = super(BirthdaysRangeFormView, self).get_form_kwargs() kwargs ['request'] = self.request return kwargs def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['title'] = "Date Selection" context['header'] = "Please select date range" return context def form_valid(self, form): self.start_date = (form.cleaned_data['start_date'], People.next_birthday) self.end_date = (form.cleaned_data['end_date'], People.next_birthday) return self.redirect_to_results() def redirect_to_results(self): self.success_url = "dates:birthdays" return redirect( self.get_success_url(), ) class BirthdaysListView(BirthdaysRangeFormView, ListView): template_name = 'dates/birthdays.html', context_object_name = "person" person = True # queryset = People.objects.order_by('next_birthday') def get_queryset(self): test = ''formularios.py:
class datefilterform(forms.Form): model = People start_date = forms.DateField( input_formats=['%d/%m/%Y'], widget=DateTimePicker( options={"format": "DD/MM/YYYY", "pickTime": False}) ) end_date = forms.DateField( input_formats=['%d/%m/%Y'], widget=DateTimePicker( options={"format": "DD/MM/YYYY", "pickTime": False}) ) People.next_birthday = start_date People.next_birthday = end_date def __init__(self, *args, **kwargs): self.request = kwargs.pop('request') super(datefilterform, self).__init__(*args, **kwargs) self.helper = FormHelper() self.helper.form_id = 'main_form' self.helper.form_class ='form-horizontal' self.helper.label_class = 'col-lg-3' self.helper.field_class = 'col-lg-8' self.helper.layout = Layout( 'start_date', 'end_date', FormActions( Submit('submit', 'Submit'), Button('cancel', 'Cancel', css_class='cancel') ) ) def clean(self): cleaned_data = super().clean() start_date = cleaned_data.get("start_date") end_date = cleaned_data.get("end_date") if not check_end_date(start_date, end_date): raise forms.ValidationError( "Incorrect Dates entered, End date must be after start date" )He hecho ListViews simples antes, pero no entiendo cómo usar "solicitud" en vistas basadas en clases.
Simplemente puede acceder a self.request en sus vistas basadas en clases.
Más bien, siga el formato, de modo que pueda manejar las solicitudes POST y GET en la misma vista.
class MyView(FormView): template_name = 'some_template.html' success_url = '...' form_class = MyForm def get(self, request, *args, **kwargs): pass def post(self, request, *args, **kwargs): pass def form_invalid(self, form, **kwargs): pass def form_valid(self, form, **kwargs): pass .....
