我的view.py看起来如下。我认为错误在于此部分。如果目前还不够,我将发布详细功能。基本上,以total为参数的模型是整数类型。
编辑1:编写整个函数,以便可以提供更多帮助。
def subjManip(request):
c= {}
c.update(csrf(request))
subj = None
c.update(csrf(request))
if request.method == 'POST':
form = SubjForm(request.POST)
if form.is_valid():
user = request.user
subj1 = form.cleaned_data['subj1']
subj2 = form.cleaned_data['subj2']
subj3 = form.cleaned_data['subj3']
if subj1 == None and subj2 == None:
raise forms.ValidationError("Both subjs cannot be empty")
tot = float (((float(0.2017 * subj1 )+ float (0.09036 * subj2) + float(0.6309 * subj3) - 5.0269)/ 4.184)
total =int(tot)
elif subj1 == None:
total = subj1
最佳答案
尝试将tot = (subj1+subj2)/2.2
替换为tot = (float(subj1) + float(subj2)) / 2.2
