Question

我想在view.py文件中获取单选按钮值，我正在获取除单选按钮值以外的所有值

我尝试使用POST和GET方法获取数据，但两者均对我不起作用 // HTML代码

<label class="col-12 col-sm-2">Rating</label>
<input type="radio" class="form-control radio-inline col-sm-1 mt-1" name="radoption" value=" 1">1
<input type="radio" class="form-control radio-inline col-sm-1 mt-1" name="radoption" value=" 2" checked>2
<input type="radio" class="form-control radio-inline col-sm-1 mt-1" name="radoption" value=" 3">3
<input type="radio" class="form-control radio-inline col-sm-1 mt-1" name="radoption" value=" 4">4
<input type="radio" class="form-control radio-inline col-sm-1 mt-1" name="radoption" value=" 5">5

// View.py代码

if request.method == "POST":
    radoption = str(request.POST["radoption"])
    return redirect("/")

/ p TypeError User（）获得了意外的关键字参数“ radoption”

整个过程都是倒退的。发布您的视图，表单和html，我将向您展示正确的方法。基本上，您不应该以相同的方式命名所有5个字段，单选按钮应该是在form.py中提供选择的一个字段。然后，您将调用form.cleaned_data.get（“ radoption”）在views.py中获取信息...

做这样的事情。

forms.py

from django import forms

NUMS= [
    ('one', 'one'),
    ('two', 'two'),
    ('three', 'three'),
    ('four', 'four'),
    ('five', 'fives'),

    ]
class CHOICES(forms.Form):
    NUMS = forms.CharField(widget=forms.RadioSelect(choices=NUMS))

views.py

from .forms import CHOICES

def name_of_url_goes_here(request):
    form = CHOICES(request.POST)

    if form.is_valid():
        selected = form.cleaned_data.get("NUMS")
        print(selected)


    return render(request, 'name_of_page.html', {'form':form})

html

<form class="form-inline" method='POST' action="" enctype='multipart/form-data'>{% csrf_token %}

  {{form.NUMS}}


</form>
