Hi i’ve to pass the variable user.user\_id by the function link\_to to the  
action show.  
the code is:

\<%= link\_to 'Show', :action =\> 'show', :id =\> user.user\_id %\>

inside the action show the value of “id” is totally different from the  
value contained in user.user\_id

Maybe is only a stupid error.  
Can anybody help me???

sorry that problem is solved…

i’ve found that the problem occurs when i try to read the results of  
find() function, and i’ve added another post.
