How to Pass Id Here (error put() missing 1 required positional argument: 'request') In form template Django


urls.py

from django.urls import path
from . import views

app_name = "poll"

urlpatterns = [
    path('', views.index, name="index"),  # listing the polls
    path('<int:id>/edit/', views.put, name='poll_edit'), ]

views.py

def put(self, request, id):
    # print("catching error ")  error before this line
    question = get_object_or_404(Question, id=id)
    poll_form = PollForm(request.POST, instance=question)
    choice_forms = [ChoiceForm(request.POST, prefix=str(
        choice.id), instance=choice) for choice in question.choice_set.all()]
    if poll_form.is_valid() and all([cf.is_valid() for cf in choice_form]):
        new_poll = poll_form.save(commit=False)
        new_poll.created_by = request.user
        new_poll.save()
        for cf in choice_form:
            new_choice = cf.save(commit=False)
            new_choice.question = new_poll
            new_choice.save()
        return redirect('poll:index')
    context = {'poll_form': poll_form, 'choice_forms': choice_forms}
    return render(request, 'polls/edit_poll.html', context)

edit_poll.html

{% extends 'base.html' %}
{% block content %}
<form method="PUT" >
    {% csrf_token %}
<table class="table table-bordered table-light">

    {{poll_form.as_table}}
    
    {% for form in choice_forms %}
         {{form.as_table}}
    {% endfor %}
    
    
</table>
    <button type="submit" class="btn btn-warning float-right">Update</button>
</form>
{% endblock content %}

this is error

line 181, in _get_response
    response = wrapped_callback(request, *callback_args, **callback_kwargs)

Exception Type: TypeError at /polls/9/edit/
Exception Value: put() missing 1 required positional argument: 'request'

I know that I am not passing argument in html but i dont know how to pass id argument in html please help me any single line of code something like default (context passing by Django)


Solution

  • You are defining a simple function, not a method in a class, you thus should remove the self parameter:

    # no self ↓
    def put(request, id):
        # …

    Note that what you are doing with the choice_forms is basically what a FormSet does [Django-doc].
