I''m terribly new to Rails, so bear with me. I have an application I am working on which deals with projects and subcontractors. There can be several subs on each project and each sub can work on several projects. I have my join table set up and has_and_belongs_to_many in both models. If I manually put data in the join table, this works in my show view: <% for subcontractor in

The rails docs are so horrible on the collection_select method. They need to show a *complete* form, and show two examples: one that calls f.collection_select(), and another that calls collection_select(), and explain the differences.

Hi, I''ve been working with rails for a couple of months now and I''m beginning to understand how things work but this has got me baffled. I want to return the user.id from a selection of a list of user names.

Hello everyone, first post to the list and a relative newbie to Rails development. Done quite a bit of JSP, PHP, HTML, XML etc and thought I would kick the tires on Rails to see if it can speed up development for internal applications.

I have two tables and a join table for them e.g. books, authors in a many to many relationship (habtm) and a join table books_authors. I can successfully search for a book that has "author.id = 2 OR author.id = 4" but I am unable to search for "author.id = 2 AND author.id = 4" This is because the result of all the joins only has one author.id column so no single row has

I''m trying to get a collection_select generated Drop-down box to display two fields from a table (first name & last name); however, I am having trouble concatenating the symbols. It appears as though any code I put in the 5th argument for collection_select is processed prior to executing the collection_select method. The code executes successfully with 1 symbol in the 5th
