在Rails Route Helper中的插值(Interpolation in Rails Route Helper)

是否有任何插入到路由帮助器的调用的方法?

我有一个部分,我通过资源(用户,画廊等)作为本地调用resource 。 我需要一个链接来编辑资源,但我需要每个资源的链接都不相同:

对于用户,链接需要使用助手edit_user_path ,对于需要使用edit_gallery_path等的edit_gallery_path

所以我需要一种方法将资源名插入辅助程序(伪代码): edit_{resource.name}_path


Is there any way of interpolating into a call to a route helper?

I have a partial in which I pass a resource (User, Gallery etc) as a local called resource. I need a link to edit the resource, but I need the link to be different for each resource:

For a user the link needs to use the helper edit_user_path, for Gallery it needs to use edit_gallery_path etc.

So I need a way to interpolate the resource name into the helper (Pseudo code): edit_{resource.name}_path

最满意答案

数据绑定后,请执行以下操作:

ddl_state.Items.Insert(0, new ListItem("Select","NA")

或者将其添加为标记:

<asp:DropDownList .. AppendDataBoundItems="true">
   <Items>
       <asp:ListItem Text="Select" Value="" />
   </Items>
</asp:DropDownList>

After data-binding, do this:

ddl_state.Items.Insert(0, new ListItem("Select","NA")

Or add it in markup as:

<asp:DropDownList .. AppendDataBoundItems="true">
   <Items>
       <asp:ListItem Text="Select" Value="" />
   </Items>
</asp:DropDownList>
