gem

问题 Given a gem that defines top-level classes that clash with some code I have written, is it possible to require the gem in such a way that all its classes are grouped inside a module I can define? For example, if an unsafe_gem defines a class: class Word # ... some code end I would need something like: class Word # My word class. end module SafeContainer # This obviously doesn't work # (i.e. the gem still defines ::Word). require 'unsafe_gem' end So that I can distinguish between: Word.new # =

问题 How do I do RESTful sign-up and sign-in using devise in Ruby on Rails (I am using version 4)? I could not find any documentation with regards to the parameters (e.g. email, password) that I should POST to the server. It seems that RESTful login using JSON data (e.g. via AJAX) is not supported out of the box in the current version of devise - the default behavior is to send back a whole HTML page for any type of request made, instead of a JSON object for handling JSON request specifically.

问题 Before I go roll my own and start pulling out the dictionary, does anyone know a rubygem to generate memorable names suitable for app keys.

问题 When I run bundle install I get An error occurred while installing libv8 (3.11.8.17), and Bundler cannot continue. Make sure that `gem install libv8 -v '3.11.8.17'` succeeds before bundling.
