Question

所以当我在 views.py 文件中打印它时，我有这个循环显示正确的输出

for x in list4:
        print x[0]
        for y in x[3]:
            print y[1]
        print "\n"

输出：

hjk

another test

但是在django模板中运行相同的循环以显示表单中的值时它会显示重复的输出

test.jinja2代码

{% extends "base.jinja2" %}
{% block content %}
{% block body %}





        {% for x in ques %}
            <form class='form-horizontal' method=POST action="/test-portal/student/test/">
            <input type="hidden" name="csrfmiddlewaretoken" value="{{ csrf_token }}">






                        <div class="form-group">

                            <input type="hidden" name="id" value={{x.0}}>
                            <label for="ques_title" class="col-sm-2 control-label" name='ques_title'>{{x[0]}}</label>
                        </div>

                        {% for y in x[3] %}
                            <!-- {% for b in y %} -->

                                <div class="form-group">
                                    <div class="col-sm-2">
                                <!-- <input type='checkbox' name='flag' id="new" value={{x}}> -->
                                        <label for="option" class="col-sm-2 control-label" name='ques_title'>{{y[1]}}</label>
                                    </div>
                                </div>
                            <!-- {% endfor %} -->
                        {% endfor %}



        {% endfor %}
                    <div class="form-group">
                        <button type="submit" class="btn btn-default" name='button' value='submit'>SUBMIT</button>
                        <!-- <td><button type="submit" class="btn btn-default" name='button' value='options'>ADD OPTIONS</button></td> -->

                    </div>

            </form>

Answer 1

正如@ alfonso.kim所述，问题是评论，因为django仍然认为评论的循环是一个实际循环所以删除

<!-- {% for b in y %} -->
<!-- {% endfor %} -->

代码工作正常。

在django模板中嵌套for循环未显示正确的输出
