如何将Django模板中的{{fieldset.fields}}转换为字符串？ [英] How turn {{ fieldset.fields }} in Django template into a string?

问题描述

Django使用{{fieldset.fields}}返回什么？如何使它成为一个字符串？

在我的模板中，我有这样的：

 code> {％for adminform％} 
< li> {{fieldset.fields}}< / li> 
 {％ifnanoaddedin fieldset.fields％} 
< li> nanoadded在这里< / li> 
 {％else％} 
< li> nanoadded不在这里< / li> 
 {％endif％} 
 {％endfor％} 
  

返回：

[（'arri'，'aconcentration'，'acat'，'anotes'，'agtlt'，'id'），（'nanoadded' 'response'，'select_charc'）]
nanoadded不在这里

所以我假设fieldset.fields没有返回一个字符串（即使它看起来像一个字符串）。如何使Django将fieldset.fields的内容看作一个字符串？感谢您的帮助！

解决方案

它看起来像字段属性返回包含两个元组的列表，因此您可能希望通过for循环运行它来检查每个元组的字符串'nanoadded'的成员资格

也许如下所示：

  {％for adminform％} 
 {％for fieldset.fields％} 
 <李> {{field}}< / li> 
 {％ifnanoaddedin field％} 
< li> nanoadded在这里< / li> 
 {％else％} 
< li> nanoadded不在这里< / li> 
 {％endif％} 
 {％endfor％} 
 {％endfor％} 
  

What does Django return with using {{ fieldset.fields }}? How can I make it a string?

In my template, I have this:

{% for fieldset in adminform %}
    <li> {{ fieldset.fields }} </li>
        {% if "nanoadded" in fieldset.fields  %}
            <li> nanoadded is here </li>
        {% else %}
            <li> nanoadded is NOT here </li>
        {% endif %}        
{% endfor %}

Here is what is returned:

[('arri', 'aconcentration', 'acat', 'anotes', 'agtlt', 'id'), ('nanoadded', 'response', 'select_charc')] nanoadded is NOT here

So I am assuming that the fieldset.fields is not returning a string (even though it looks like a string). How can a make Django see the contents of fieldset.fields as a string? Thanks for you assistance!

解决方案

It looks like the fields property returns a list that contains two tuples, so you might want to run it through a for loop to check each tuple for the membership of the string 'nanoadded'

Perhaps like this:

{% for fieldset in adminform %}
    {% for field in fieldset.fields %}
    <li> {{ field }} </li>
        {% if "nanoadded" in field  %}
            <li> nanoadded is here </li>
        {% else %}
            <li> nanoadded is NOT here </li>
        {% endif %}       
    {% endfor %} 
{% endfor %}
