Question

我是Django的新手。我想用另一个模型中的动态标签/详细名称填充模型Score的表单：问题。

基本上，每个用户有5个当前的问题，他们将以“是”或“否”的形式对其进行评分

我将用户当前五个问题的数据保存在字典中，并且可以将此字典传递到视图或模板中，但不知道如何使用字典来填充表单的标签/详细名称。

#Model
class Score(models.Model):
yesno = ((0,"No"),(1,"Yes"),)
oneScore =models.IntegerField(choices=yesno,default='none')
twoScore =models.IntegerField(choices=yesno,default='none')    
threeScore =models.IntegerField(choices=yesno,default='none')
fourScore =models.IntegerField(choices=yesno,default='none')
fiveScore =models.IntegerField(choices=yesno,default='none')
author = models.ForeignKey('auth.User')
date_created = models.DateTimeField(blank=False, null=False)

#Model
class QuestionManager(models.Manager):
    def current_for_user(self,user):
        question1 = Question.objects.filter(author=user,statementNumber=1).order_by('-id').first()
        question2 = Question.objects.filter(author=user,statementNumber=2).order_by('-id').first()
        question3 = Question.objects.filter(author=user,statementNumber=3).order_by('-id').first()
        question4 = Question.objects.filter(author=user,statementNumber=4).order_by('-id').first()
        question5 = Question.objects.filter(author=user,statementNumber=5).order_by('-id').first()

        question_list = {"1":question1,
                        "2":question2,
                        "3":question3,
                        "4":question4,
                        "5":question5}
        return question_list

class Question(models.Model):
    statementNumber=models.IntegerField(choices=NUMBER, default='1',verbose_name="The number of the statement")
    text = models.CharField(max_length=500,help_text="Enter your text", verbose_name="New Statement")
    author = models.ForeignKey('auth.User')
    date_created = models.DateTimeField(blank=False, null=False)
    objects=QuestionManager()

#Form
class ScoreForm(forms.ModelForm):
    class Meta:
        model = Score
        fields = ('oneScore','twoScore','threeScore','fourScore','fiveScore','bigScore')

#View
def score(request):
    user = request.user
    questions = Question.objects.current_for_user(user)

    if request.method == "POST":
        questions = Question.objects.current_for_user(user)
        form = ScoreForm(request.POST)
        if form.is_valid():
            score = form.save(commit=False)
            score.author = request.user
            score.save()
            return redirect('scoresheet',pk=score.pk)
    else:
        form = ScoreForm()

    return render(request,'MC/score.html',{'form': form,'questions':sorted(questions.items())})

我不确定你追求的是什么，但你可以将任何你喜欢的东西传递给表格：

class ScoreForm(forms.ModelForm):

    def __init__(self, questions, *args, **kwargs):
        super().__init__(*args, **kwargs)
        for num, question in questions.items():
            self.fields.get('some_field').label = question


#View
def score(request):
    user = request.user
    questions = Question.objects.current_for_user(user)
    if:
        # ...
    else:
        form = ScoreForm(questions)

    return render(request,'MC/score.html',{'form': form})

使用动态变量填充表单标签/详细名称
