Rails - Jun 2009 - A simple problem....

Hey guys - thanks for reading this.

I''m trying to use the onclick event to redirect the user via a ruby
function.  The code is within a "view" html.erb file.  The original
table has an entry that works perfectly fine:

[code] <td><%= link_to ''Show'',
project%></td> [/code]

...but I''d like for the user to be able to click anywhere on that row
and be directed to the "show" page.  If you''re feeling
generous, can you
also explain why, in this case, "project" suffices, while in this
case:

[code] <td><%= link_to ''Edit'',
edit_project_path(project) %></td>
[/code]

I say "edit_project_path(project)"?  Where would this method be
located?
My attempt for the onclick event:

<tr onmouseover="ChangeColor(this, true);"
              onmouseout="ChangeColor(this, false);"
              onclick="<%= remote_function( :url => { :controller
=>
''projects'', :action => ''show'', :id =>
project.id }) %>;" [/code]



The ChangeColor methods are defined and function properly, but clicking
the row does nothing :(.

Thanks again for your time :).

This method is created for you by rails, based on your routes. There
is another helper, project_path that gives the path for the show
action, but you don''t have to use that as link_to assumes
that''s what
you want to do if you just pass it an active record
object.

What does your controller code look like ? Is the request made ? does
this product syntactically correct html (eg it wouldn''t if the output
from remote_function contained a " ) ?

Thanks for the help Fred,

Hmmm...the produced HTML reads as follows:

<tr onmouseover="ChangeColor(this, true);"
              onmouseout="ChangeColor(this, false);"
              onclick="new Ajax.Request(''/projects/1'', 
{asynchronous:true, evalScripts:true,
parameters:''authenticity_token='' +
encodeURIComponent(''EFK4UoM20XdzwDeneOTmVqtQYqG3Lgp+9swBrULFUsw='')});">

My controller code does contain a "show" def, which is requested in
the
":action =>" declaration.  When the working link is clicked, the
"show"
def does the following correctly:

def show
    @project = Project.find(params[:id])

    respond_to do |format|
      format.html # show.html.erb
      format.xml  { render :xml => @project }
    end
  end

But the remote_function does not.
