我有此项目表及其详细信息，并且我实现了一种使用“提交”按钮“选择”一些项目的方法，该按钮将提交每个项目的所有选中复选框。
这是复选框的代码：
<input name='quiz-pids' id='checkbox-{{ quiz.id }}' type="checkbox" value="{{ quiz.id }}" required>
如您所见，我已经在复选框值中传递了quiz.id。这是我正在使用的提交按钮：
<input type="submit" class="btn btn-primary select-btn myitems-select-btn"
value='Finalize Items'
required>
在这里，除了提交之外，我没有提到此按钮的作用。此功能处理通过提交按钮输入的数据。
class UploadedItems(ListView):
model = ItemBatch
ordering = ('uploaded',)
context_object_name = 'plan'
template_name = 'classroom/teachers/item_list.html'
def post (self, request, *args, **kwargs):
# get the selected quizs
quizs = request.POST.getlist('quiz-pids')
# retrieves thoses quizes from the database:
print("pids returned are ", quizs)
# items = ItemBatch.objects.filter(pid__in=quizs)
for i in quizs:
print("before", i)
i = get_object_or_404(ItemBatch, id=i)
i.rtd = 'True'
i.save()
print("after", i.truck_type) # print("items are",items)
return redirect('teachers:upload_batch')
如您所见，由于此行request.POST.getlist('quiz-pids')，我的函数“ post”仅接受测验-pid。现在我的问题是，我也想删除并取消选择我的项目。但是，由于我的函数只能接受测验-pid，因此我不能仅为此创建另一个按钮。
我尝试添加更多功能：
def post (self, request, *args, **kwargs):
# get the selected quizs
quizs = request.POST.getlist('quiz-pids')
deleted_items = request.POST.getlist('delete-pids')
unselect_items = request.POST.getlist('unselect-pids')
# retrieves thoses quizes from the database:
print("pids returned are ", quizs)
# items = ItemBatch.objects.filter(pid__in=quizs)
for i in quizs:
print("before", i)
i = get_object_or_404(ItemBatch, id=i)
i.rtd = 'True'
i.save()
print("after", i.truck_type) # print("items are",items)
for j in unselect_items:
j = get_object_or_404(ItemBatch, id=i)
j.rtd = 'False'
j.save()
for k in deleted_items:
k = get_object_or_404(ItemBatch, id=i)
k.delete()
k.save()
但是，由于我项目前面的每个复选框的名称均为name='quiz-pids'，因此我无法生成Deleted_items列表或unselect_items列表。我不可能给每个项目三个不同的复选框。我该怎么办？
这是我完整的html和views函数：
@method_decorator([login_required, teacher_required], name='dispatch')
class UploadedItems(ListView):
model = ItemBatch
ordering = ('uploaded',)
context_object_name = 'plan'
template_name = 'classroom/teachers/item_list.html'
def get_queryset (self):
return ItemBatch.objects.filter(uploaded_by=self.request.user)
def get_context_data (self, **kwargs):
context = super().get_context_data(**kwargs)
latest = ItemBatch.objects.filter(uploaded_by=self.request.user).order_by('-time').annotate(
truncated_time=Trunc('time', 'minute', output_field=DateTimeField()))
context['last'] = ItemBatch.objects.filter(uploaded_by=self.request.user).annotate(
truncated_time=Trunc('time', 'minute', output_field=DateTimeField())).filter(
truncated_time=Subquery(latest.values('truncated_time')[:1])).order_by('-rtd')
return context
def post (self, request, *args, **kwargs):
# get the selected quizs
quizs = request.POST.getlist('quiz-pids')
deleted_items = request.POST.getlist('delete-pids')
unselect_items = request.POST.getlist('unselect-pids')
# retrieves thoses quizes from the database:
print("pids returned are ", quizs)
# items = ItemBatch.objects.filter(pid__in=quizs)
for i in quizs:
print("before", i)
i = get_object_or_404(ItemBatch, id=i)
i.rtd = 'True'
i.save()
print("after", i.truck_type) # print("items are",items)
for j in unselect_items:
j = get_object_or_404(ItemBatch, id=i)
j.rtd = 'False'
j.save()
for k in deleted_items:
k = get_object_or_404(ItemBatch, id=i)
k.delete()
k.save()
print("pids converted are ", quizs)
return redirect('teachers:upload_batch')
