django Edit records in Listview - django

Question

I have a ListView that lists all questions from the Question model.
the models.py is:
class Question(models.Model):
question_text = models.CharField(max_length=200, unique=True)
pub_date = models.DateField(verbose_name='date published')
def __str__(self):
return self.question_text
now I want users can edit question_text. I tried this in views.py:
class UpdateDirectry(generic.list.ListView, generic.edit.FormMixin):
model = Question
template_name = 'accounts/editable_directory.html'
form_class = forms.EditListForm
def get_context_data(self, *, object_list=None, **kwargs):
context = super(UpdateDirectry, self).get_context_data()
context['object_list'] = Question.objects.filter(question_text__startswith='Who')
return context
and in the template:
<form method="post">
{% csrf_token %}
<table class="table">
<thead>
<tr>
<th scope="col">#</th>
<th scope="col">Q</th>
<th scope="col">D</th>
</tr>
</thead>
<tbody>
{% for object in object_list %}
<tr>
<th scope="row">{{ forloop.counter }}</th>
<td><input type="text" value="{{ object.question_text }}"></td>
<td>{{ object.pub_date }}</td>
</tr>
{% endfor %}
</tbody>
</table>
<input type="submit" value="Submit">
</form>
I can edit the question_text but when I click submit button nothing happens (just a white page) and no records change in the database.
How can I really edit records with the submit button?
This is what the template shows:
Update 1: ## this is what I exactly want in view (this image is in admin with list_editable):

How can do the exact thing in a view?

Answer 1

Just use a ModelFormSetView from Django Extra Views:
from extra_views import ModelFormSetView
class UpdateDirectry(ModelFormSetView):
model = Question
template_name = 'accounts/editable_directory.html'
form_class = forms.EditListForm
and in your template:
<form method="post">
{{ formset }}
<input type="submit" value="Submit" />
</form>

You have to import UpdateView from :
from django.views.generic.edit import UpdateView
from django.views.generic.edit import FormMixin
from .forms import EditListForm
class UpdateDirectry(UpdateView, FormMixin):
model = Question
template_name = 'accounts/editable_directory.html'
form_class = EditListForm
