使用字段标签作为占位符与django-widget-tweaks [英] Use field label as placeholder with django-widget-tweaks

问题描述

我正在使用django-widget-tweaks，无法找出如何添加字段变量作为占位符，如下所示：

I am using django-widget-tweaks and unable to figure out how to add a field variable as placeholder, like the following:

<div class="col-sm-10">
 {{ field|append_attr:"class:form-control"|append_attr:"placeholder:field.label" }}
 {% if field.help_text %}
   <p class="help-block"><small>{{ field.help_text }}</small></p>
 {% endif %}
</div>

field.label 将字符串field.label作为页面上的占位符。

field.label above does not evaluate and puts the string "field.label" as the placeholder on the page.

一些SO帖子建议注册一个自定义

Some SO posts suggest registering a custom tag/filter which seems complicated for something this simple.

推荐答案

我现在使用 render_field 来渲染字段，而不是使用模板过滤器，它似乎工作。

I am now using render_field to render the field instead of using template filters and it seems to work.

<div class="col-sm-10">
  {% render_field field class="form-control" placeholder=field.label %}
  {% if field.help_text %}
     <p class="help-block"><small>{{ field.help_text }}</small></p>
  {% endif %}
</div>

似乎窗体变量不能在模板过滤器中使用，只能与 render_field （尽管django-widget-tweaks documentation < a>不明确表示）。

It seems form variables cannot be used within template filters and can only be used with render_field (though the django-widget-tweaks documentation doesnt say that explicitly).
