如何在此处传递 Id错误 put() 缺少 1 个必需的位置参数：'request'在表单模板 Django

如何解决如何在此处传递 Id错误 put() 缺少 1 个必需的位置参数：'request'在表单模板 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 %}

这是错误

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'

我知道我不是在 html 中传递参数，但我不知道如何在 html 中传递 id 参数，请帮助我 任何单行代码类似于 default（由 Django 传递的上下文）

解决方法

您正在定义一个简单的函数，而不是类中的方法，因此您应该删除 self 参数：

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

请注意，您对 choice_forms 所做的基本上就是 FormSet does [Django-doc]。
