Hello, thanks for reading. I used scaffolding to set my pages up, and I''ve been editing them to get the effect that I want, but I''m running into a few problems. The first problem: I have 2 drop down menus, with pre-determined choices, let''s say, "Ruby, Python, Java" are in the first drop down, and "Is awesome!, Sucks, etc." are in the second. I then want to concatenate them with a space in between, and have that as the input into my database. Currently I have: <%= f.select(:part1, List::NAME) %> <%= f.select(:part2, List::TYPE) %> Where NAME is the first list, and TYPE is the second, they''re defined in the list model. The drop down lists work, but I have no idea how to go about concatenating "part1" and "part2", and nothing that I''ve tried works. Second problem: I want another drop down list, except that I want the choices to be from another table in the database. In other words, I have a table called users, which just has two fields: id and name. I want every user name to come up in this list. The name itself is also what I want to be saved to the database for that entry. I''ve been programming for a while, and just started picking up Ruby a few months ago, and I completely love it. This is my first time working with web apps, and it''s been pretty challenging so far, and I''m hoping that I can get the hang of it soon. Thanks anyone for the input! -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

For the first one, I just kept the same code, but added in the controller params[:list][:full] = params[:list][:part1] + " " + params[:list][:part2] right before @list = List.new(params[:list]) in the create method. All of the creating stuff works perfectly now, but I''m having trouble with edit. The drop down Name list is already picking the right name, which is good, but the other one isn''t. Right now, the code is: <%= f.select(:part1,List::NAME,{}, {:size=>5}) %> <%= f.select(:part2,List::TYPE,{}, {:size=>5}) %> Each select has 5 options, so I opted to just use a select field instead of a drop down. I tried adding :selected=>"Ruby" to the first one, but it didn''t do anything. I believe that the current values which should be defaulted can be found by full.split(" ")[0] and [1], but not really sure how to implement that here. Thanks again for the response =) I think I''m starting to get a better feel for this. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
