For example, suppose I have this table: id INT(11) PK group CHAR(40) name CHAR(40) value CHAR(128) updated_at DATETIME Sample rows: group name value --------------------------- main something

Hi, I began experimenting with habtm relationships, and so I created a stories table, a tags table, and a stories_tags table referencing the former 2. When I create a "story", I want to add several tags to it. Then, the model should create those tags and link them to the respective stories, and for the tags that already exists, just link them to the story. I tried something like

Hi, I want to add data from a fixture file to a table inside a migration.

Also, if I have a file, say, with 200,000+ records, what would be the best method (performance-wise) to go

Hi, Let''s say I have the following hierarchy of tables: Group <- parent Location <- child of Group School <- child of Location Phone <- child of School Then, if I want to do this: Location.find(...someparms..., :include => [:schools, :group, :phones]) I get an association error (Association was not found).

Hi, I was thinking of doing this with a stored procedure, but I thought it could be better implemented in Rails. I have several tables that hold a counter cache for other tables, which aren''t directly related. For example: Table ''schools'' has records that belong_to table ''counties'', and that table has records that belong_to table

Hi, Due to some performance issues, I want to use a custom query for a find method: def find_in_state(state) State.find :all, :limit => 10, :conditions => [''s.id = ? AND '' + ''s.id = c.state_id AND c.state_id = ? AND '' + ''c.id = col.county_id AND

Hi, I wanted to be able to use some Rails code inside CSS files, so I set up a controller (StylesController) to serve CSS files that reside inside the controller''s view folder when the browser requests /stylesheets/:action So in the controller I just define empty actions with the names I want my style sheets in (ie: def cooleffects end - that would respond to

Hi, As per another member''s suggestion, I''m trying to user STI.

Hi, So thanks to Zed I was able to get lighty/scgi and a Rails app running. I know this might not be the best place to post this, but I guessed there may be several others with similar experiences here. So, the following step is to have several apps each in its on subdirectory. I tried the following to no avail: $HTTP["url"] =~ "^/tango/" { server.document-root =
