Rails 3.1.3 Hi. I''m a little confused with Devise and ActionMailer. It seems that Devise has its own way of sending mails through ActionMailer. Does it generate Mailer class when "rails g devise..." command is executed? Or do I need to do some special command in order to generate Mailer? I have certainly set up a devise User table but there is no Mailer class for it,

Rails 3.1.3 Hi. I have designed the database used for my travel plan application. You should be able to look at the diagram in the link below, hopefully. https://cacoo.com/diagrams/biDSyxh8yzk2kIeg ("belongs_to" is omitted since it''s obvious) Basically, the application can list the destinations from a choice of the departure. Not mention that the departure_id (integer) and

Rails 3.1.3 I have tables, Video and Script having association, Video 1 --- n Script So, every Script needs the parent id, in this case, video_id. If I simply create a new Script instance, the view renders as follows. <%= render :partial => "new_script", :locals => { :script => Script.new(:video_id => @video.id)} %> which works fine. Now I would like to

Rails3.1.3 I have db type, startp:integer I need to change it to float. More specifically, 1.2, 45.1, 143.8 ... I have two questions: 1. Is removing and adding the field through migration the only way? in other words, is there a single command to change the type? 2. Is there anyway to limit the decimal place to only one? 56.3, 34.2... are acceptable, but 23.112, 77.34, ... are

Rails 3.1.3 I believe this is a very very fundamental question, but since I am new to Rails, it''s more productive to ask someone to point out what I need to do. Say, I have a search method that generates a list of youtube videos. I have completed this part. And also, I have set up a database, Video, whose fields are video_title and URL. I need to place a button to each of these video

Rails 3.1.3 I have changed a regular scaffold action a bit so that it can save using ajax.
