How to organize dynamic display of data from the database in django?

Question

Django

There is a task - to dynamically display data from the help base of the drop-down list.
(In the case of php, this is pretty easy to do with an ajax request.)
Is there a basic way in django to solve this?

Answer 1

JsonResponse
Also useful: csrf ajax

(In the case of php, this is fairly easy to do with an ajax request.)

It's easy to do this in django too.

Answer 2

You can do this:

<p><select name="pr" required id="prepod">
      <option selected  value="0">Выбрать</option>
      {% for prepod in prepods %}
        <option value="{{ prepod.pk }}">{{ prepod.name }}</option>
      {% endfor %}
      </select>
      <input type="submit" value="Отправить"></p>

Or in forms.py you create:

class PrepodForms(forms.ModelForm):
    prepodname = forms.ModelChoiceField(queryset = Prepod.objects.all(),
                empty_label="Выберите преподавателя",
                widget=forms.widgets.Select(attrs={'class':'dropdown'}),label="Преподаватель")

    class Meta:
        model = Prepod
        fields = ()

and paste in html:

{{ grform.gruppname }}
    <input type="submit" value="Показать расписание">
