Hi, Is there some way to produce an anchor that looks like the following using helpers, or should I just code it in the rhtml like this? <a href="#" onmousedown="javascript:foo(); return false"> Thanks, Brad -- Bradley Mazurek

I''m trying to marshal some information I have in Javascript, and send it over an AJAX request to the server, specifically to be stored in a model on the server side. I have some Javascript routines I wrote that gather information about the user selection. I see that the link_to_remote has a :before option in which I can write Javascript to collect what I need, but right now I''m

Hi, I haven''t done any associations before, so please forgive my incorrect use of terminology... If I set up a has_many :through association, can I manipulate the associated instances directly (like an Array), or do I need to manipulate the join model? For example, suppose I have two classes and the associated join model: class foo has_many :foo_bars has_many :bars, :through

Hi, Just got my first Mac. I''m trying to install rails on it, using the instructions in the rails wiki: http://wiki.rubyonrails.com/rails/pages/HowtoInstallOnOSXTigerUsingDarwinPorts I go to install mysql, and the version of mysql supported by DarwinPorts appears to be 4.1.18. But all the sites appear to only have 4.1.19 or 4.1.20. So it looks like DarwinPorts is over a month out

Hi, I''m relatively new to ruby and rails. I would like to have a sidebar component call one of several other constituent components. I''ve run into some problems, and so I''ve pruned things back to a relatively simple case. I have a sidebar component. Renders great. In it''s layout, I call render_component for another component I would like in the sidebar.

Hi all, I''m trying to do multiple render_to_string() calls in a method call, and I''m getting attributes being modified in unexpected ways. @left_sidebar = render_to_string( :partial ..... ) puts @left_sidebar.id (-> 123456) @right_sidebar = render_to_string( :partial .....) puts @left_sidebar.id (-> 234567 WTF!?!?!) puts @right_sidebar.id (-> 345678)

I''m working on a system that has a series od "bids" associated with "posts". Vurrently when a bid is placed I have it creating a new row each time in the "bids" table. The bids table has id, post_id, and user_id. The logic is to check to see if a bid already exists with a given post_id and user_id. If it does, then just update the "amount"

Hello List, I''m a bit spent on this problem, and my code might be whack. I seem to be encountering a problem where the primary key on a join table is not being resolved correctly. I will elaborate after some code bits. I am creating the join table using migrations, and relevant model code is this: class Post < ActiveRecord::Base has_and_belongs_to_many :records

Hi, I am trying to create a simple point system and display the total on my index page. So I have my db basically setup like this: Posts id, body, created_at, user_id Post_points id, post_id, user_id, created_at, value So as you can see I am allowing other users to create points on the post and my db will store who gave the point as well. "value" is the point value which can

I''ve been fighting with a Double Render Error. I have some sidebar partials that I render to strings in my application controller''s before_filter: @left_sidebar_for_layout = render_to_string(:partial => ''shared/left_sidebar'') Then in my application layout, I simply add them as a string, like I would @content_for_layout This normally works fine. However,

Is a component supposed to be able to call another component (which presumably could call another component)? Brad -- Bradley Mazurek

Trying to model a bunch of users that have friends that are other users. clearly a job for has_and_belongs_to_many, but the trick is, they have ratings for their friends. I have gone through the Rails Recipes book, and it seems like I''m trying to combine the self-referential many-to-many recipe (12) and the many to many relationships where the relationship itself has data recipe (16). So

I have more or less the same problem. I''m trying to build a system where users can enter their friends. But the solutions seems not to work for me. I used same sql: CREATE TABLE `friends` ( `user_id` int(11) NOT NULL default ''0'', `friend_id` int(11) NOT NULL default ''0'', KEY `user_id` (`user_id`), KEY `friend_id` (`friend_id`),

Hi, I have a user model and a privilege model. They have the has_and_belongs_to_many relationship. Here are the model defs: class User < ActiveRecord::Base belongs_to :status has_and_belongs_to_many :privileges end class Privilege < ActiveRecord::Base has_and_belongs_to_many :users end Now I have a migration script to create the join table and populate a few users with some

Hi everyone. I''m trying to figure out how to implement site-wide tagging for my website. I have a rails-based weblog that supports tagging posts. There''s a has_and_belongs_to_many relationship between posts and tags. I''d like to now reuse those tags for tagging links as well. Where I have a posts_tags table with post_id and tag_id fields, I''d like to

So I''ve worked through Agile Web Development with Rails and I''m now trying my first little app to get into the swing of things. Its a task tracking app where people can create tasks and assign them to others, and also log time against the tasks. I''m having trouble working out the model relationships. This is what I''ve got so far, but its not right as

Hey there, I''m in the muck of a major rails project, and need a bit of advice. Google isn''t much help in this case, so I came here. I''m trying to set up a URL structure as follows: url.com/username/blog/post_id where the user has_many posts and the post belongs_to user. I''m using the friendly_id plugin to enable easy lookup with the user''s username,

Hi all I am new to Rails, and obviously I''m missing something, I''ll get straight to the question: A User has many operations (granted to her), each Operation is associated with an OperationType. Each Operation may be associated with more then one User. So the model goes like this: class User < ActiveRecord::Base has_and_belongs_to_many :operations

hey, i my database i have users and groups, each user can get in different groups my db structure: table groups: id, name, basegroup, firm_id table users: id, firstname, lastname, email table groups_users: group_id, user_id my relation is a many to many: class Group < ActiveRecord::Base has_and_belongs_to_many :users end class User < ActiveRecord::Base has_and_belongs_to_many

Mysql::Error: Unknown column ''users.team_id'' in ''where clause'': SELECT * FROM users WHERE (users.team_id = 1) LIMIT 1 i
