Question

这是我模板文件中的代码

{% load section_settings %} ## Loading a template tags
{% section_settings declaration.id user.id as the_section_setting %}

现在价值：

the_section_setting = {'A': {'included': True, 'editable': True, 'alwaysIncluded': False, 'complete':False}, 'C': {'included': False, 'editable': True, 'alwaysIncluded': False, 'complete': False}}

当我尝试在js脚本中运行此代码时，现在在我的模板文件中：

<script type="text/javascript">

function initTree(showline){    
    {% for section in the_section_setting %}    
    alert("{{ the_section_setting[section]['included'] }}")
    {% endfor %}
        }   
</script>

抛出错误'tuple' object has no attribute 'has_header'。基本上我已经在python shell中测试了它，它对我来说很好。但不是在模板中。我在做什么错误。我想要dict中每个元素的included键的值。在此先感谢。

我收到以下错误：

AttributeError at /declaration/2991/detail

'tuple' object has no attribute 'has_header'

正确的语法是

<script type="text/javascript">

function initTree(showline)
        {    
           {% for section, secval in the_section_setting.iteritems %}
           alert("{{secval.included}}")
           {% endfor %}
        }   
</script>

为了更加详细，我会选择像

这样的东西

<script type="text/javascript">

function initTree(showline)
        {    
           {% for section, secval in the_section_setting.iteritems %}
               {% if secval.include %}
                   alert("The {{ section }} is included.")
               {% else %}
                   alert(""The {{ section }} is not included.")
               {% endif %}
           {% endfor %}
        }   
</script>

'tuple'对象没有属性'has_header'
