类型错误：表单上的'int'和'str'实例之间不支持'>'

Question

我正在从cs50 web编程Edx学习python并在表单添加任务上工作。如果表单有效，代码将添加任务，如果表单无效，则返回到(服务器端验证)的页面。

我正在使用Python3.

我代码:

# created two form inputs 
class NewTaskForm(forms.Form):
task = forms.CharField(label="Task/kaam")
priority = forms.IntegerField(label="Priority", min_value=1, max_value="8")
# to show the added tasks
def index(request):
return render(request, "tasks/index.html", {'tasks': tasks})

# to add the task 
def add(request):
if request.method == "POST":
form = NewTaskForm(request.POST)
if form.is_valid():
task = form.cleaned_data["task"]
tasks.append(task)
else:
return render(request, "tasks/add.html", {"form": form})
return render(request, "tasks/add.html",
{"form": NewTaskForm()}
)

您在这里使用了字符串:

# created two form inputs 
class NewTaskForm(forms.Form):
task = forms.CharField(label="Task/kaam")
priority = forms.IntegerField(label="Priority", min_value=1, max_value="8") #<--- max_value="8"

试题:

# created two form inputs 
class NewTaskForm(forms.Form):
task = forms.CharField(label="Task/kaam")
priority = forms.IntegerField(label="Priority", min_value=1, max_value=8)
# to show the added tasks
def index(request):
return render(request, "tasks/index.html", {'tasks': tasks})

# to add the task 
def add(request):
if request.method == "POST":
form = NewTaskForm(request.POST)
if form.is_valid():
task = form.cleaned_data["task"]
tasks.append(task)
else:
return render(request, "tasks/add.html", {"form": form})
return render(request, "tasks/add.html",
{"form": NewTaskForm()}
)
