我正在尝试在rails应用程序中为按钮添加数据属性。当我查看应用程序时,我收到以下错误。

切换button_to调用中的第二个和第三个参数:
<li class="download cols-lg-4 pull-right">
<% if (version.app[:app_type] == 'ios') %>
<%= button_to 'Download', "itms-services://?action=download-manifest&url=#{CGI::escape version.plist_url}", data: {build: version.build_number}, class:"download-btn btn-primary btn-small pull-right" %>
<% else %>
<%= button_to 'Download', version.plist_url, data: {build: version.build_number}, class: 'download-btn btn-primary btn-small pull-right', method: :get %>
<% end %>
</li>

In the docs您会看到:data
是:html_options
的一部分,这是第三个参数。第二个参数通常是按钮的目标,通常是RESTful路径或包含操作目标的哈希,有时是方法。如果没有阻塞,:html_options
就是第二个参数之后的所有内容。尝试类似:
<%= button_to 'Download',
version.plist_url,
data: {build: version.build_number},
class: 'download-btn btn-primary btn-small pull-right',
method: :get %>
