Problem retrieving user id

Rails
1

I have a problem, I use a find.params[:id] to display a user from a
list, and then I want to edit that information. I have a separate
action for the edit, named change_user_details, and I retrieve the
user id the same way I do for the audit_user with find.params[:id].
The problem is that the action change_user_details does not want to
retrieve the current viewed user id. It gives the error Couldn’t find
User without an ID.
Here is the code of the two actions and the two forms.

def audit_user
@user = User.find(params[:id])
end

def change_user_details
@user = User.find(params[:id])
end

Username: <%= @user.username %>

Email: <%= @user.email %>

IP: <%= @user.user_ip %>

First Name: <%= @user.firstname %>

Last Name: <%= @user.lastname %>

<%= link_to(‘Change’, :action => ‘change_user_details’) %>
|
<%= link_to(‘Back’, :action => ‘list_users’) %>

Editing User Information

<% form_tag :action => ‘update_user’, :id => @user do %>

Firstname
<%= text_field 'user', 'firstname' %>

Last Name
<%= text_field 'user', 'lastname' %>

Email
<%= text_field 'user', 'email' %>

<%= submit_tag(“Update”)%>

<% end %>

<%= link_to(‘Back’, :action => ‘audit_user’) %>

Hi

Perhaps you can take a look at activescaffold…

Thanks, took care of the problem :slight_smile:

Yep, it worked. Before that I used a newly created session to track the
id.
But it worked. Thanks a lot.

Right, because params[:id] is empty.

Username: <%= @user.username %>

Email: <%= @user.email %>

IP: <%= @user.user_ip %>

First Name: <%= @user.firstname %>

Last Name: <%= @user.lastname %>

<%= link_to(‘Change’, :action => ‘change_user_details’) %>

This doesn’t pass an id. You need to explicitly pass it:

<%= link_to ‘Change’, :action => ‘change_user_details’, :id => @user
%>
