Question

我创建了以下自定义帮助程序来添加带图标的链接：

module ApplicationHelper

    def link_with_icon_to(label, icon, url, data = {}, method = nil)
        render "shared/link_with_icon", label: label, icon: icon, url: url, data: data, method: method
    end

    def edit_link(url)
        link_with_icon_to 'Editar', 'fa fa-pencil', url
    end

    def remove_link(url)
        link_with_icon_to 'Excluir', 'fa fa-trash', url, method: :delete, data: { confirm: 'Are you sure?' }
    end
end

_link_with_icon.html.erb

<%= link_to url, method: method, data: data do %>
    <i class="<%= icon %>" /><span><%= label.html_safe %></span>
<% end %>

我正在以这种方式使用它们：

<% @insurance_companies.each do |insurance_company| %>
            <tr>
              <td><%= insurance_company.name %></td>
              <td><%= insurance_company.cnpj %></td>
              <td><%= edit_link edit_insurance_company_path(insurance_company) %></td>
              </td>
              <td><%= remove_link insurance_company %></td>
            </tr>
          <% end %>

但是remove_link帮助程序无效。不会显示确认信息，也不会删除数据。

我的助手有什么问题？

这是可能的，因为您没有将其他选项（数据和方法）传递给link_to。

无法立即确认/验证这一点，但我认为您可以解决此问题的方法是：

def link_with_icon_to(label, icon, url, opts = {})
    render "shared/link_with_icon", label: label, icon: icon, url: url, opts: opts
 # there definitely better ways of handling this, but can't think of another right now
end

# _link_with_icon.html.erb
# spread the opts hash here. the opts hash could be {data: {element: 'whatever'}, method: :delete} etc.
<%= link_to url, **opts do %>
    <i class="<%= icon %>" /><span><%= label.html_safe %></span>
<% end %>

无法在自定义帮助程序上使用方法和确认属性来创建带图标的链接
