Hi all, I''m new to RoR
I finally got a RoR environment working on my PC with instantrails 2.0.
Here is my problem.
I created a database with a "Users" table.
It''s structure is the following :
Name, Surnmame, City, age...
The table containing the Users was succesfully scafolded and I have the
adress "localhost:3000/users" running with all the CRUD functions ! :D
now I want to add a link at the botom of the index page allowing me to
filter the users living in Paris (and ultimately, a textbox where I can
put in any search criteria). But getting the filter for the Paris Users
would already end a huge headache.
I added at the bottom of the index page a "Paris" link after the
prebuilt "new user" link.
the bottom of my index page looks like this :
******************************************************************
<%= link_to ''New user'', new_user_path %>
<%= link_to ''paris'',{:controller => "users",
:action => "paris" }%>
********************************************************************
I added the "Paris" control in "users_controller.rb" wich I
left empty
but I get the same error no matter what I put in it...
****************************************
def paris
end
****************************************
Everytime I click on the link I get the following error :
********************************************************
"ActiveRecord::RecordNotFound in UsersController#show
Couldn''t find User with ID=paris"
********************************************************
I am unable to add new controls as I always get "Couldn''t find
User with
ID=paris" no matter what I put in the Paris action.
There i probably some RoR concept I didn''t get right...
thanx for your help !

I find this is the easiest way for me since then I can just restrict access to the CRUD that scaffold generated for me and use it as part of my Admin area. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I can verify that this does work although it probably isn''t DRY enough for most rails developers. Open terminal in project directory and run: script/generate controller paris add the following to the controller: def index #put your database code here end and now your link becomes: <%= link_to :controller => :paris %> -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Your problem is with your routes, you have the standard restful routes
setup so it''s interpretting the action as an id. I would suggest using
GET variables to do the filter. I would use something like this
<%= link_to "Users", :action => "index", :filter =>
"Paris" %>
now in your index action you do something like
if(params[:filter])
@users = User.find(:all, :conditions => "users.city =
''#{params[:filter]}''")
else
@users = User.find(:all)
end
Hope this works for you

I agree with Matt. "filter" and "search" are really indexes with more specific criteria. If you take the approach he''s suggesting you keep the footprint smaller. @Brandon: Speaking of not DRY... aren''t you logically suggesting that he create a new controller for every interesting city he can think of? You''re repeating all the lookup code, the routes, etc simply for the sake of a simple, pretty url. Keeping things DRY is a principle that crosses the boundaries of classes.

thank you so much Matt Mongeau... This forum is really helpfull to beginners as there isn''t that much good RoR documentation on the net (or perhaps I''m not going on the right sites...) Does anybody know about a good lightweight editor where I can open and edit my RailsApps from my instantrails directory?

My background is php and in learning rails I found that it made more sense to me if I just left the scaffold pages "as is" but add a berfore filter to restrict access to them. This give me my "admin" functionally that I normally require. As for the extra controller I normally make an extra controller that can accept parameters and be dynamic. I use this controller to display my pages that the end users see. The example I described is not how I normally do things but was more of an example of a method he could use to get past the problem he was having. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thanks for all your help. I am wondering now how I can put a searchbox at the botom of the index page to search through the users (by age, city ect...) I tried to inspire myself with the content in "new.html.erb" for the textbox and submit button but I''m not getting anywhere... thanks in advance! -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
