Question

我正在尝试在Django中创建一种调查应用程序，其中问题（称为类别）和选项会自动显示在一页上。类别和选项的数量是任意的-页面需要显示所有内容。像这样：

Category 1:
    Response a
    Response b

Category 2:
    Response c
    Response d
    Response e

etc.
[submit]

我已经创建了一个工作视图，很大程度上依赖于我的模板，而不完全依赖于form.py。（尚未进行表单验证。）现在所有选项都是单选按钮，但是稍后我将使用不同类型的输入，例如复选框，文本等。

我正在寻找一种方法来（更多）依赖forms.py和views.py，而不是在模板中包含大多数逻辑。

这是我的代码：

models.py:

class Category(models.Model):
    category_name = models.CharField('Kategoriens navn', max_length=100)
    category_created_at = models.DateTimeField(default=timezone.now, editable=False)

class CategoryOption(models.Model):
    category = models.ForeignKey(Category, on_delete=models.CASCADE)
    option_name = models.CharField('Knappens navn', max_length=100)
    option_created_at = models.DateTimeField(default=timezone.now, editable=False)

class Response(models.Model):
    project = models.ForeignKey(Project, on_delete=models.CASCADE)
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    response_created_at = models.DateTimeField(default=timezone.now, editable=False)

class ResponseValues(models.Model):
    response = models.ForeignKey(Response, on_delete=models.CASCADE)
    category = models.ForeignKey(Category, on_delete=models.CASCADE)
    option = models.ForeignKey(CategoryOption, on_delete=models.CASCADE)


views.py:

def project(request):
    categories = Category.objects.filter(project=project)   # project variable excluded for simplicity

    if request.method == 'POST':
        response = Response(project=project, user=request.user)
        response.save()

        for category in categories:
            category_id = str(category.pk)
            option = request.POST.get(category_id)
            if option:
                option = CategoryOption.objects.get(id=option)
                responsevalues = ResponseValues(response=response, category=category, option=option)
                responsevalues.save()

    context = {'categories': categories,}
    return render(request, 'survey/project.html', context)


project.html:

<form action="" method="post">
    {% csrf_token %}
    {% for category in categories %}
        <h4>{{ category.category_name }}</h4>
            {% for option in category.categoryoption_set.all %}
                <input type="radio" name="{{ category.pk }}" value="{{ option.pk }}" id="{{ option.pk }}"><label for="{{ option.pk }}">{{ option.option_name }}</label><br>
            {% endfor %}
    {% endfor %}
    <input type="submit" value="Save">
</form>

使用forms.py在Django中创建动态填充的一页多问题调查表？
