Hi there, I have a User model and a Profile model. A user has_one profile, and a profile belongs_to a user. The profile model contains a user_id column as the foreign key.

I also want the profile model to be filled in with the appropriate user_id foreign key (I don''t care

I am a freshman when it comes to RoR, and I haven''t been able to figure this out. I need to figure out how to query records in my database using form check boxes (or radio buttons) then display them in that same instance. What would this look? I have been told that just putting a question mark after here, :conditions => field = ?, but what would the argument look like? Thanks in

Hi all! I can''t post to this list from my regular gmail account. I receive fine, but whenever I send mail, no joy. Any ideas?

Hi, I''m sure there is an easy way to do this, but I just can''t see it: I have a large amount of rooms, that are for different purposes, and for only one ''purpose'' do I want to create a specific subclass.

I''m new to Ruby and RoR but excited to learn what I can do with RoR; I have Pickaxe second edition and want to get "Agile Web Development with Rails" but I''m aware that the book was published some while before RoR version 1.0 was released. Has a lot changed since then, and would I therefore be advised to wait for a second edition of AWDwR? Many thanks in advance

Hi, My application has a table of People that has information about them, and I want to have a subset of those people as Users - people that can login to the application. What is the best way to do this? Add columns to People that only Users would use? I''ve read the threads on single table inheritance, but it seemed a little bit wasteful: 10,000 people vs 50 users For those more

I am designing an application to run a fishing tournament I am hosting. Each fish entered will be given a point total based on the length of the fish and the species of fish. Each species has a point multiplier. For Example Trout have a multiplier of 10 so a 20 inch Trout would have a score of 200. My conundrum is in where and when do I calculate the points. The options I have come up

Hi, This seems simple but I cant get it to work... I have a table with 4 or 5 columns and 20-30 rows. I''d like to have the ability to click anywhere in a particular row to fire an action, such as bringing up a "Details" page for the clicked row. This would eliminate the need to generate a "Details" link at the end of every row, which is what I have now and looks

Hi all, I emailed Sebastian awhile back about this, but I know he is busy, so I''m asking for your help. I''m using the latest version of file_column from SVN, or the non-SVN version (doesn''t matter), but on some files, file_column will create 0kb files. The tmp directory will contain the correct file size, and I copied the temp over the 0kb file, and then it

Hi, I have validation that checks for uniquess, but when the user enters a non-unique attribute, I''d like to present *what* the existing object is: For example, if I specified an IP address for a Device, and that IP already exists for another Device, I''d like to display the attributes of the existing device to help the user out. Right now, it just gives the user the obvious

I know this is a more Ruby thing, but I want to strip out all non-word (\W) characters from a string. Is there a regexp way to do this? Right now, I have: params[:object][:item].sub!(/(\W)*/,'''') but that only removes the first instance, not all non-word chars. Thanks, - Nic.

Hey all, I''m doing something of a node-node connection, and I want to eventually walk each node, pulling data from each node, and displaying the path. The DB table would just be columns of IDs that link to each other My catch is that these aren''t generic nodes, they are Models that could potentially connect to each other, and I don''t know how to

Hey all, I''m using the Agile book, and I wanted to try some of the demo code. So I dropped one of the folders ''web2'' into my webroot of Apache, and tried to access a controller from the browser. I just get the usual 404, but I have an identical directory structure setup w/RoR code that I''ve generated w/scaffolds, and that works fine. Am I missing something
