在WTForms字段上设置数据属性 [英] Setting data attributes on a WTForms field

问题描述

我想将data-属性添加到表单字段以与Bootstrap集成。我在模板中尝试了以下内容：

$ $ p $ $ $ $ c $ {form.test（data-toggle =toggle，data-size = mini，data-on =是，data-off =No，type =checkbox）}}

得到这个错误：

$ p $ TemplateSyntaxError：expected token'，'，got'='


为什么我得到这个错误，我该如何解决？

I want to add "data-" attributes to a form field for integration with Bootstrap. I tried the following in a template:

{{ form.test(data-toggle="toggle", data-size="mini", data-on="Yes", data-off="No", type="checkbox")}}

and got this error:

TemplateSyntaxError: expected token ',', got '='

Why did I get this error and how do I fix it?

解决方案

You need to use valid Python names as the variable names. Therefore names like "data-toggle" are invalid because they have a "-" in them. Change the names to use underscores, like "data_toggle". WTForms automatically converts "_" to "-" for keywords it doesn't recognize.
