原标题:Helper for edit/show/destroy Link with an image

i) 设法使冰箱能够使用这些风格:

edit(category)
destroy(post.comment.first)
show(@user)

并且,我们获得了与冰貌相关的选定链接。

谁能告诉我,如果我这样做是正确的,或者是否有更好的魔法?

def show(object)
  link_to image_tag("admin/show.png"), eval("admin_{object.class.to_s.downcase}_path(#    {object.id})")
end

def edit(object)    
  link_to image_tag("admin/edit.png"), eval("edit_admin_#{object.class.to_s.downcase}_path(#{object.id})")
end

def destroy(object)    
  link_to image_tag("admin/destroy.png"), eval("admin_#{object.class.to_s.downcase}_path(#{object.id})"), :method=>:delete, :confirm=>"Do you really want to delete this?"
end

这样做是罚款的,但是为了寻找魔法铁路:-

最佳回答

eval改为send,并将downcase 改为。 铁路公约

send("admin_{object.class.to_s.underscore}_path", object.id)

BTW, 铁路可以为你做:

# equals to your `show(object)`
link_to image_tag( admin/show.png ), [:admin, object]
