How to use null=>false in a migration file?
You are trying to update the provider and uid columns to not allow null values, and you have written your migration correctly. This error is arising because one or more of them (at least provider) already contains records with null values. You'll have to either drop the records with null...

Why does this Travis deploy to Heroku fail?

Cannot add object as hash value in Rake: TypeError: no implicit conversion of DropboxClient into String
I get the same error in irb, and it makes sense to me. ENV is for getting and setting environment variables, which have string values. So you can't store something that's not a string in it. I'm not sure why you're trying to do that anyway? Are you trying to...
How do I run Rails/Rake from another directory?
ruby,ruby-on-rails-3.1,rake,bundler
Without you showing the error message you are getting, I'm assuming it has less to do with Bundler than it does Rake. When the rake command is run, it searches for a Rakefile starting in the current directory and traversing up the tree until it finds one. You can override...
Using Rake with Rufus

ruby-on-rails,ruby,rake,rake-task
The problem is the line Rails.application.config.method. The standard method Kernel#method is used to retrieve a method object and (kind of) a reserved word since it is defined on all objects. To fix this, you must name your custom config differently, for example Rails.application.config.cat_method.

Why does default rake task run specs in Rails app?
If you have rspec-rails in your Gemfile, then when the gem is loaded by Rails is will execute this line: https://github.com/rspec/rspec-rails/blob/v3.2.1/lib/rspec-rails.rb#L19 load "rspec/rails/tasks/rspec.rake" which in turn defines the default rake task: https://github.com/rspec/rspec-rails/blob/v3.2.1/lib/rspec/rails/tasks/rspec.rake#L6 task :default => :spec That's why the default rake task runs the specs in your Rails app. Furthermore,...
