Hi all, I''ve put new code into my app so that an administrator will have extra privileges (administer users, edit pages).

When I use find_by_name method I get LIMIT 1 result. > SELECT "users".* FROM "users" WHERE "users"."age" = 25 LIMIT 1 But the "age" column is not unique in my table and its value may repeat.

Hi, All through my current project, I''ve been assuming that rails is clever enough to prevent SQL injections automatically. Is this right? If not, what''s the best way of doing it? -Nathan

Given this code (which renders rjs), I''m faced with the fixture- driven way of spec-ing or mocking. How the heck to you mock this so the code at line (2) and (4) work right?

I''m trying to understand how to select only certain rows in my database using RoR. As a test I try to find certain clients by adding this code in my list view... <% clientlist = Client.find_by_client_status_id(1) %> <% if clientlist %> <= This prevents me from getting nil errors. <% for client in clientlist %> <= This seems to try and call

I am working on an application where there are many different screens to access the data in a particular record/row. I have links to each data entry screen at the top.
