I'm using ModelForm to create a form, then I'm using this form to create a new instance in the database. But the form is not saving data, it's just reloading the page when the form submmited.

I'm also uploading an image.

forms.py

from django import forms
from django_summernote.widgets import SummernoteWidget

from events.models import Event


class EventCreateForm(forms.ModelForm):
    class Meta:
        model = Event
        fields = "__all__"
        widgets = {
            "content": SummernoteWidget(),
        }

    def __init__(self, *args, **kwargs):
        super(EventCreateForm, self).__init__(*args, **kwargs)
        for visible in self.visible_fields():
            visible.field.widget.attrs["class"] = "form-control"

        self.fields["start_datetime"].widget.attrs["class"]  = " datetimepicker"
        self.fields["finish_datetime"].widget.attrs["class"]  = " datetimepicker"
        self.fields["image"].widget.attrs["class"] = "custom-file-input"
        self.fields["address"].widget.attrs["rows"] = 3

CodePudding user response：

A FormView does not save the form. The .form_valid(…) method can be overridden to specify what to do in case the form is valid. It makes here more sense to use a CreateView [Django-doc], which will save the form and thus store the data into the database:

from django.views.generic import CreateView

class EventFormView(LoginRequiredMixin, CreateView):
    template_name = "events/event_form.html"
    form_class = EventCreateForm
    model = Event
    success_url = reverse_lazy("dashboard:events:home")
