我已经挣扎了大约一个小时，似乎无法找到解决方案。
我有一个django模型，我使用ModelForm创建了表单。表单在视图中，我想在提交到数据库之前操作表单变量。问题是我似乎无法从表单的数据库中获取正确的列。相反，它看起来像是引用另一个相关表中的列。有什么建议吗？
模型
class RoutinePlans(models.Model):
routine = models.ForeignKey(Routines, on_delete='CASCADE')
exercise = models.ForeignKey(WeightExercises, on_delete='PROTECT')
set = models.IntegerField()
set_type = models.ForeignKey(SetType, on_delete='PROTECT')
reps = models.IntegerField()
day = models.IntegerField()
week = models.IntegerField()
def __str__(self):
return self.routine.name
class Routines(models.Model):
name = models.CharField(max_length=50)
level = models.ForeignKey(RoutineLevels, on_delete='PROTECT')
creator = models.ForeignKey(User, on_delete='CASCADE')
status = models.TextField(max_length=50)
description = models.TextField(max_length=255, null='TRUE', default=None)
def __str__(self):
return self.name
表单
class PlanForm(forms.ModelForm):
DAY_CHOICES = (('1', '1'), ('2', '2'), ('3', '3'), ('4', '4'), ('5', '5'), ('6', '6'), ('7', '7'))
day = forms.ChoiceField(widget=forms.Select, choices=DAY_CHOICES)
class Meta:
model = RoutinePlans
exclude = ['routine']
视图
#not sure if this view would have anything to do with the error but figured I would include it to give the full perspective
def createplan(request):
form = forms.CreatePlan()
if request.method == 'POST':
form = forms.CreatePlan(request.POST)
if form.is_valid():
obj = form.save(commit=False)
obj.name = request.POST['name']
obj.creator_id = request.user.id
obj.status = "DRAFT"
obj.save()
return redirect('fitnessmanagement:editplan', id=obj.pk)
else:
print('error form invalid')
variables = {'form': form}
return render(request, template_name='createplan.html', context=variables)
def editplan(request, routine_id):
form = forms.PlanForm()
routine_name = Routines.objects.get(id=routine_id).name
if request.method == 'POST':
form = forms.PlanForm(data=request.POST)
if form.is_valid():
obj = form.save(commit=False)
#this is where I want to put obj.routine but the form will only pull fields from the Routines model and not the Routine Plans
obj.save()
return redirect('fitnessmanagement:editplan', routine_id=routine_id)
# variables to populate plan
plan = RoutinePlans.objects.filter(routine_id=routine_id)
plan_weeks = RoutinePlans.objects.filter(routine_id=routine_id).values('week').distinct()
plan_dayss = RoutinePlans.objects.filter(routine_id=routine_id).values('day', 'week').distinct()
plan_excercise_name = RoutinePlans.objects.filter(routine_id=routine_id).values('day', 'week', 'exercise_id', 'set_type_id').distinct()
plan_excercise = RoutinePlans.objects.filter(routine_id=routine_id).prefetch_related('exercise')
names = WeightExercises.objects.all()
setDetails = RoutinePlans.objects.filter(routine_id=routine_id).values('set', 'reps', 'day', 'week', 'exercise', 'set_type')
set_type = SetType.objects.all()
# end variables to populate plan
variables = {'form': form,
'id': routine_id,
'routine_name':routine_name,
'plan': plan,
'plan_weeks': plan_weeks,

'plan_exercise_name': plan_excercise_name,
