Django HTML for loop with filter

Question

在我的django项目中，我有一个呈现问题标题的HTML，在问题标题中我有问题项。在我的模型中，问题标题和项是两个不同的实体。我需要显示每个标题，仅显示与该标题相关的项目。因为它显示了所有问题的所有项目，没有任何过滤器。非常感谢任何帮助！

型：

class Question(models.Model):
question              = models.CharField(max_length=240)
mission_section       = models.ForeignKey('Mission_Section', on_delete=models.CASCADE)
type_question         = models.ForeignKey('Type_Question', on_delete=models.CASCADE)
categories_question   = models.ForeignKey('Categories_Question', on_delete=models.CASCADE, default=1)
order                 = models.IntegerField(default=1)
def __str__(self):
return self.question
class Question_Option(models.Model):
question = models.ForeignKey('Question', on_delete=models.CASCADE,default=1)
option = models.CharField(max_length=240)
correct = models.BooleanField()
order = models.IntegerField(default=1)

视图：

class Questions(LoginRequiredMixin, FormView):
template_name = "questions.tmpl"
def get(self, request, pk):
context = {
'pk': pk, 
'section': Mission_Section.objects.get(pk = pk ), 
'questions_items': Question_Option.objects.filter(question__mission_section__pk=pk).order_by('order','pk'), 
'questions': Question.objects.filter(mission_section__pk = pk ),
'question_types' : Type_Question.objects.all(),
'questions_categories': Categories_Question.objects.all()}
return render(self.request, self.template_name, context)

.HTML

<input type="hidden" class="form-control" id="section" name="section" value="{{section.id}}" required>
<h1>{{ section.name }}</h1>
<div id="contentDiv">
<ol>
{% for question in questions %}
<div name="question" class="form-group" id="question-{{question.id}}" >
<form class='my-ajax-form' id="form-question-{{question.id}}" method='GET' action='.' data-url='{{ request.build_absolute_uri|safe }}'>
<li><div class="input-group">
{% csrf_token %}
{{ form.as_p }}
<input type="text" value= "{{question.id}}" id="question" name="question-hidden" class="form-control">
<input type="text" value= "{{question.question}}" id="question_name_{{question.id}}" class="form-control" aria-label="Amount" onchange="UpdateQuestion({{question.id}})">
</div>
</form>
<br>
<!-- Options -->
<div id = "question_content_{{question.id}}" name="question-options" class="collapse">
<ol class="example list-group">
{% for qi in questions_items %}
<li class="list-group-item d-flex justify-content-between align-items-center" id={{qi.id}} name="opt-{{question.id}}-{{qi.id}}" onclick="setCorrect({{qi.id}},{{question.id}})" contenteditable="true">{{ qi.option }}
<span class="badge badge-warning badge-pill">-</span>
</li>
{% endfor %} </ol>
<div>
<div class="d-flex justify-content-center">Add Option</div>
<div class="d-flex justify-content-center"> <br><i class="fa fa-plus-circle fa-1x" aria-hidden="true"></i></div>
</div>
</div>
</div></li>
{% endfor %} </ol>

Answer 1

使用这个答案我想通了 Django 模板中的双循环

我需要的是：

<div id = "question_content_{{question.id}}" name="question-options" class="collapse">
{% csrf_token %}
{{ form.as_p }}
<form class='ajax-form-option' id="form-option-{{question.id}}" method='GET' action='.' data-url='{{ request.build_absolute_uri|safe }}'>
<ol class="example list-group">
{% for qi in question.question_option_set.all %}
<li class="list-group-item d-flex justify-content-between align-items-center" id=option-{{qi.id}} name="opt-{{question.id}}-{{qi.id}}">
<div contenteditable="true">{{ qi.option }}</div>
<div>
<button type="button" name='option-check' class="btn btn-light" value={{qi.id}} id="check-option-{{question.id}}-{{qi.id}}">
<i class="fas fa-check"></i>
</button>
<button type="button" class="btn btn-warning" id="delete-option-{{question.id}}-{{qi.id}}" onclick="deleteOption({{qi.id}})">
<i class="fa fa-trash" aria-hidden="true"></i>
</button>
</div>
</li>
{% endfor %} </ol>
<div onclick="CreateOption({{question.id}})">  
<div class="d-flex justify-content-center">Add Option</div>
<div class="d-flex justify-content-center"> <br><i class="fa fa-plus-circle fa-1x" aria-hidden="true"></i></div>
</div>
</form>
