Hi, I''ve got my little app working pretty well. I''m using pretty much the model and table layout from my previous thread, as suggested by Bill Katz: <http://www.ruby-forum.com/topic/52506#26260> I have the Create page working and a delete Match page working, which along with the appropriate record in the Matches table, removes the linked items in the competitions table.

Matches has a match number and a team_id field (along with several other fields) and teams has a team_number field (again, along with

Hi all, My question is somewhat complicated, but bear with me. My project has a number of models: User, Program, and Team. Users belong to multiple Programs. Programs have multiple teams, but Teams belong to one program. For each Program a User belongs to, he can belong to multiple Teams.

Hi, I''m working on an app - my first Rails - and am looking for some suggestions on the best way (or good way) to set up my models / DB. In general there are teams and matches; a team will participate in multiple matches, and in each match there will be 6 teams - 3 vs. 3.

I am using nested forms with multiple instances of various of the forms. The problem I cant figure out is how to maintain state for the select between postbacks. I am using ''options_from_collection_for_select'' and in this the last param is to be the selected value, but given the dynamic nature, the value is going to depend on the iteration of the form builder. If I manually force

the vm form is getting cluttered, this patch simply add collapsable sections to the form, making the 'resources' and 'network' sections collapsed by default - icon added - methods added to the js - reorganization / cleanup in rhtml, indentation changes, no functionality or content changes --- src/app/views/vm/_form.rhtml | 109

Even if I put in an integer, like this, <%= select_tag(fruit.id, "<option>No Contract</option>" + options_from_collection_for_select(@fruit_types, "id", "kind", 3)) %> the list still displays the first option (No Contract) in the list. What am I doing wrong? I''ve looked

People, I want to design a historical sports db for my old school.

Is there a problem with this? Doesn''t it just mean that there will be a student table

I just have a few questions about join tables. From my understanding the following applies (correct me if I''m wrong): 1.Join tables are always named with the names of the two associated tables, in alphabetical order, separated by an underscore. 2.The foreign key fields are named with the name of the table they are referencing, with _id appended. 3.The foreign key is referencing a
