问题 I'm trying to mock a method call to an outside API inside one of my rails controllers (in this case, Instagram.get_access_token) and I'm having some trouble. As written, the code is still calling the real Instagram.get_access_token method. How do I have the controller use my simple mock instead? sessions_controller.rb: class SessionsController < ApplicationController require 'instagram' include ApplicationHelper def auth_callback response = Instagram.get_access_token(params[:code], redirect

问题 My computer works on a proxy. So in order to install gems I use the following command gem install -p http//#{proxy-server}:#{port} rails If i use the normal gem install command, I get an error could not find gem . I installed rails 3.1 today and tried to create a new project.

问题 I am using the bootstrap-timepicker for rails and I am using it in a form helper. It works very well if there is only one instance of it.

These widgets originally returned the html as a string. So in my erb I have somethink like this. <% @template.widgets.each do |widget| %> <%= widget.show_me %> <% end %> As the views of the widgets became more complex I start using partials to render them, calling the ActionView::Base render method from inside my widgets (please don't throw up

问题 When using SMTP settings in Rails for sending e-mail, you need to provide a username and password for it to send email from your account. But isn't it a little dangerous to put your password to the site's email account in plain text in your code? Is there a more secure way to do this? config.action_mailer.smtp_settings = { :address => "address_here", :port => 'port_#_here', :domain => "example.com", :authentication => :plain, :user_name => "user@example.com", :password => "foobar", :enable

I've added the button n modified the function called by this form jus to display "in execute" and "in delete" for now to check if the second 'delete' button is functioanal.

问题 I feel like there is a large step from where Rails tutorials end and where I can actually use it to do what I need. This is manifesting itself in this relatively simple case: I want a page that takes inputs and calculates a volume. Ideally, this would do it with AJAX because it always irritates me when a simple page makes me reload it. I've been doing this in IRB with: radius = 25; length = 0.15;( radius**2) * Math::PI * length *1e-3 # radius in microns, length in meters, answer in
