Rails 3.1.3 rspec-rails (2.11.4) rspec 2.11.1 I am new to rspec. I don''t quite understand tests for POST create part. I have generated scaffold, and simultaneously it generated controller_spec.rb as well. it "assigns a newly created plan as @plan" do post :create, {:plan => valid_attributes}, valid_session assigns(:plan).should be_a(Plan)

Rails 3.1.3 After watching http://railscasts.com/episodes/258-token-fields?autoplay=true I have installed the similar functionality to my app. However, def index @cities = City.all ... does in fact give the list of all cities in the text field, but def index @cities = City.where("name like ?", "%#{params[:q]}%") ... does NOT

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 3.2.11 Sidekiq latest My app continues background jobs that generate texts as the output. class ProcessText include Sidekiq::Worker def perform(name, count) puts "executing..." @feed = Feed.first @feed.process # here it returns String results! end end What I want is basically how to send (or push?) the result texts to a particular web

Rails 3.1.3 I have a model ''Airline'', whose STRING column is ''company'' only. Also, another model ''Plan'' has an INTEGER column ''airline_id''. I would like to show the ''company'' name (string) in a template like <% @plans.each do |plan| %> Airline: <%=

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 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 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 Globalize3 latest I am not sure if I can ask this question here in general Rails forum. But I''ll try. Currently I am using a gem, Globalize3, which is useful for model I18n. https://github.com/svenfuchs/globalize3 Say, I have a model City, having only one column, name. City names appear differently depending on the language, so perhaps this particular gem is useful.

Rails 3.1.3 I have changed a regular scaffold action a bit so that it can save using ajax. All I needed to do was adding ":remote => true" in <div id="script_new"> <%= form_for script, :remote => true do |f| %> <!-- HERE!!! --> <%= f.hidden_field :video_id %> <%= f.text_field :text %> <%= f.submit "save" %>

say I have a matrix and lists like x <- matrix(c(12.1, 3.44, 0.1, 3, 12, 33.1, 1.1, 23), nrow=2) x.list <- lapply(seq_len(nrow(x)), function(i) x[i,]) if I want a column of the matrix x, I write x[, 2] for example. But how can I do something similar for a set of lists, x.list, above? > x.list [[1]] [1] 12.1 0.1 12.0 1.1 [[2]] [1] 3.44 3.00 33.10 23.00 unlist(x.list)[,2] does

Rails 3.1.3 I am hoping some of you may give me suggestions about user input helper methods. I have a large set of model, Flight, and its fields are airline, flight_name, departure, destination As you can imagine, the flight data will be very large; it could be thousands if it is international. I will ask users to input the desired flight plan, and it will be crucial if the users make

I need to develop a simple list manipulation. Although it seems easier to do it in matrix form, but I need it in list form. I have a matrix x <- matrix(c(12.1, 3.44, 0.1, 3, 12, 33.1, 1.1, 23), nrow=2) for list form example, the conversion is x.list <- lapply(seq_len(nrow(x)), function(i) x[i,]) ### list version calcnorm=function(a, b){ diff <- mapply("-", a, b)

Hello, So, after learning ruby on rails and building a great app on my local machine, I need to find a host, deploy, and of course maintain a (staging and) production environment. This all seems very confusing, and I''d like to learn this in an organized manner, step by step: I''ve come across the names: Unicorn, nginx/apache, capistrano, Thin/mongrel, Engine Yard, EC2, etc.,
