I want to make four links with different arguments but the same  
action.  
The first time, I did it like this:  
\<%= link\_to ‘xx’ {:action =\> xx, :id =\> 0} %\>  
\<%= link\_to ‘xx’ {:action =\> xx, :id =\> 1} %\>  
\<%= link\_to ‘xx’ {:action =\> xx, :id =\> 2} %\>  
\<%= link\_to ‘xx’ {:action =\> xx} %\>  
yes, I want the forth link with no argument.  
But it didn’t work. when current url is xx/1, then the forth link  
bring me to xx/1 , xx/2, xx/0 as the same.  
I solve it by changing the argument name, something like  
\<%= link\_to ‘xx’ {:action =\> xx, :ids =\> 0} %\>  
then the url looks like xx?ids=0  
everything works  
Can anyone tells me more details about it ? or just where can I find  
the answer.  
Thanks a lot!

Yeah you are right, i have the same event like yours.

The forth link " \<%= link\_to ‘xx’ {:action =\> xx} %\> " should have the  
same meaning with " \<%= link\_to ‘xx’ {:action =\> xx, :id =\> 0} %\> ", In  
this case I usually put additional params like you have done too "\<%=  
link\_to ‘xx’ {:action =\> xx, :ids =\> 0} %\> ", I have no idea how it  
could be like that.

Please check, are you using render in your controller to show  
destination link?

Because your link is [http://localhost:3000/xx/1](http://localhost:3000/xx/1), when you run \<%=  
link\_to ‘xx’ {:action =\> xx} %\>, ruby will have your params[:id] from  
your original url.  
it looks like reference params[:id].

so if your url [http://localhost:3000/xx/what\_ever\_id](http://localhost:3000/xx/what_ever_id), the link of “\<%=  
link\_to ‘xx’ {:action =\> xx} %\>” will be “\<%= link\_to ‘xx’ {:action =\>  
xx, :id =\> what\_ever\_id} %\>”, understand? you can use \<%= link\_to ‘xx’  
{:controller =\> yy, :action =\> xx} %\> OR xx , i not  
check it but maybe it works.
