我的models.py:
class Classname(models.Model):
class_name = models.CharField(max_length=8)
def __str__(self):
return self.class_name
class Sectionname(models.Model):
class_name = models.ForeignKey(Classname)
section_name = models.CharField(max_length=1, default='A')
def __str__(self):
return self.section_name
class Teachername(models.Model):
classname = models.ForeignKey(Sectionname)
secname = models.ForeignKey(Classname)
teachname = models.CharField(max_length=50)
def __str__(self):
return self.teachname
my views.py:
def add_teach(request):
if request.method == 'POST':
form = TeachernameForm(request.POST)
if form.is_valid():
form.save()
return HttpResponseRedirect(reverse('student:listteach'))
else:
print(form.errors)
else:
form = TeachernameForm()
return render(request, 'add_teach.html', {'form': form},)
my form.py:
class TeachernameForm(ModelForm):
classname = forms.ModelChoiceField(queryset=Classname.objects.all())
secname = forms.ModelChoiceField(queryset=Sectionname.objects.all())
class Meta:
model = Teachername
fields = ('classname', 'secname', 'teachname',)
当我提交TeacherForm时。我收到了上述错误。我尝试了许多技巧,但没有得到解决方案。请有人建议我修复。
答案 0 :(得分:0)
class Teachername(models.Model):
classname = models.ForeignKey(Sectionname)
secname = models.ForeignKey(Classname)
这应该是:
classname = models.ForeignKey(Classname)
secname = models.ForeignKey(Sectionname)
