Rails: redirect_to :controller=>'tips', :action => 'show', :id => @tip.permalink
提问by john
I tried to redirect rails to show action by passing controller, action, and params. However, rails ignores the name of action totally!
我试图通过传递控制器、动作和参数来重定向 rails 以显示动作。然而，rails 完全忽略了动作的名称！
what I got is http://mysite/controllername/paramId
我得到的是 http://mysite/controllername/paramId
so i have error message....
所以我有错误信息....
here is the action code I used:
这是我使用的操作代码：
def update
@tip = current_user.tips.find(params[:id])
@tip.attributes = params[:tip]
@tip.category_ids = params[:categories]
@tip.tag_with(params[:tags]) if params[:tags]
if @tip.save
flash[:notice] = 'Tip was successfully updated.'
redirect_to :controller=>'tips', :action => 'show', :id => @tip.permalink
else
render :action => 'edit'
end
end

This might be a temporary "get around". Using render, it works very well....
这可能是暂时的“绕过”。使用渲染，它工作得很好......
if @tip.save
flash[:notice] = 'Tip was successfully updated.'
render :action => 'show', :id => @tip.permalink
# redirect_to :controller=>'tips', :action => 'show', :id => @tip.permalink
else
render :action => 'edit'
end

Why fight the framework?
为什么要对抗框架？
redirect_to @tip
And you can shorten your code by using the :notice option.
您可以使用 :notice 选项缩短代码。
redirect_to @tip, :notice => 'Message here'

If its a REST resource route, the routing is actually correct. A GETrequest on /tips/idactually calls the showaction. Because of the way it is routing, my guess is that you routed it with map.resources, and this is correct.
如果是 REST 资源路由，则路由实际上是正确的。上的GET请求/tips/id实际上调用了该show操作。由于它的路由方式，我的猜测是您使用 路由它map.resources，这是正确的。
