我有一个窗体，其中有一个字段用于选择一个方法来对对象进行排序。但是，当我引用该字段以获取它的值时，它就等于呈现此表单的HTML代码。我如何解决这个问题？
我的表单：
class sortChoice(forms.Form):
CHOICES = [('sbd', 'Сортировать по дате'),
('sbp', 'Сортировать по популярности')]
choice = forms.ChoiceField(choices = CHOICES, widget = forms.RadioSelect, label = 'Сортировка по')
我的观点：
@login_required(login_url = 'login')
def vacancyListView(request):
searchQueryNavbar = request.GET.get('search_navbar', '')
searchQueryVLpage = request.GET.get('search_vlpage', '')
form = sortChoice()
print(form['choice'])
if searchQueryNavbar or searchQueryVLpage:
if searchQueryNavbar:
searchQuery = searchQueryNavbar
else:
searchQuery = searchQueryVLpage
if form['choice'] == 'sbp':
queryset = Vacancy.objects.filter(Q(name__icontains = searchQuery) | Q(salary__icontains = searchQuery) | Q(competences__icontains = searchQuery)).order_by('-viewsAmount')
if form['choice'] == 'sbd':
queryset = Vacancy.objects.filter(Q(name__icontains = searchQuery) | Q(salary__icontains = searchQuery) | Q(competences__icontains = searchQuery)).order_by('-creationDate')
else:
queryset = Vacancy.objects.all().order_by('-viewsAmount')
context = {
'objectList':queryset,
'form':form
}
return render(request, "vacancyList.html", context)
打印（从['choice'])的控制台输出：
<ul id="id_choice">
<li><label for="id_choice_0"><input type="radio" name="choice" value="sbd" required id="id_choice_0">
Сортировать по дате</label>
</li>
<li><label for="id_choice_1"><input type="radio" name="choice" value="sbp" required id="id_choice_1">
Сортировать по популярности</label>
</li>
</ul>
您必须为表单分配数据。请参阅绑定表单和未绑定表单
form = sortChoice(request.POST or request.GET)
调用form.is_valid()后，您将能够访问cleaned_data。
然后您的代码如下所示：
@login_required(login_url = 'login')
def vacancyListView(request):
searchQueryNavbar = request.GET.get('search_navbar', '')
searchQueryVLpage = request.GET.get('search_vlpage', '')
form = sortChoice(request.POST or request.GET)
if searchQueryNavbar or searchQueryVLpage:
if searchQueryNavbar:
searchQuery = searchQueryNavbar
else:
searchQuery = searchQueryVLpage
if form.is_valid():
selected = form.cleaned_data.get("choice")
if selected == 'sbp':
queryset = Vacancy.objects.filter(Q(name__icontains = searchQuery) | Q(salary__icontains = searchQuery) | Q(competences__icontains = searchQuery)).order_by('-viewsAmount')
if selected == 'sbd':
queryset = Vacancy.objects.filter(Q(name__icontains = searchQuery) | Q(salary__icontains = searchQuery) | Q(competences__icontains = searchQuery)).order_by('-creationDate')
else:
queryset = Vacancy.objects.all().order_by('-viewsAmount')
context = {
'objectList':queryset,
'form':form
}
return render(request, "vacancyList.html", context)
我将更改choice键,如下所示：
CHOICES = [
('creationDate', 'Сортировать по дате'),
('viewsAmount', 'Сортировать по популярности')
]
那么您就不必使用if else并这样做：
queryset = Vacancy.objects.filter(
Q(name__icontains = searchQuery) | Q(salary__icontains = searchQuery) | Q(competences__icontains = searchQuery)
).order_by('-%s' % form.cleaned_data.get("choice"))
