如何在simple_form中向表单标记添加数据属性?

I'm using garlic.js to validate my forms. Garlic.js recommends adding a data-attribute on the form tag.

我用大蒜。来验证我的表单。大蒜。js建议在表单标记上添加一个数据属性。

Here's what I need to generate:

以下是我需要生成的:

<form data-validate="parsley">

I'm having issues to generate this data attribute on the form tag. I tried everything and nothing worked. Anyone has a solution to this?

我有一些问题要在表单标签上生成这个数据属性。我什么都试过了，但什么都没用。有人能解决这个问题吗?

Try this:

试试这个:

<%= simple_form_for @entity, :html => {:"data-validate" => 'parsley'} do |f| %>
    <!-- inputs -->
<% end %>

From the comment below, to have the form include an HTML5 data attribute with no value try the following:

从下面的评论中，有一个没有价值的HTML5数据属性，尝试如下:

<%= simple_form_for @entity, :html => {:"other-data-value" => ''} do |f| %>

By setting the attribute to an empty string the form helper renders just the attribute.

通过将属性设置为空字符串，表单助手只呈现属性。

For anyone stumbling across this in 2016 using either the newer version of Rails (4) or the newer version of Parsley (2) here is what you'll need to do:

对于任何在2016年使用最新版本的Rails(4)或更新版本的Parsley(2)遇到这种情况的人，以下是您需要做的:

First of all to activate parsley with data attributes in the new version you add data-parsley-validate now instead of the data-validate="parsley" from version 1 of Parsley. Now lets get that to work with rails form_for.

现在让我们使用rails form_for。

Even if you're not using parsley, this is how to insert a data attribute in Rails 4.

即使您没有使用parsley，这也是在Rails 4中插入数据属性的方法。

<%= form_tag '/login', :"data-parsley-validate" => '' do %>
    <!-- inputs -->
<% end %>

So basically the difference is not using the html=>{} hash. I tried that to see if that trick would work and at least for me my markup looked like this:

因此，基本上不同之处不在于使用html=>{}哈希。我试着看看这个技巧是否有用，至少对我来说，我的工资是这样的:

<form action="/login" method="post" html="{:data-parsley-validate}">
    <!-- inputs -->
</form>

But by simply putting the data attribute directly in there as a symbol with an empty string as the corresponding value and it worked perfectly. This is the markup I received.

但是，只需将数据属性直接放在那里，作为一个符号，并使用一个空字符串作为相应的值，它就可以很好地工作。这是我收到的加价。

<form action="/login" method="post" data-parsley-validate>
    <!-- inputs -->
</form>

In other words its perfect. So thats how to use Rails 4 to get data attributes in your form_tag.

换句话说，它是完美的。这就是如何使用Rails 4在form_tag中获取数据属性的方法。
