Sinatra Activerecord：为Psych：Module调用的私有方法“ load”（NoMethodError）

Question

I have a Sinatra app that uses Activerecord gem. Everything used to run well until some moment my code just stopped working. The only thing that I did in between is update my Gemfile with bundle update .

Now this code:

require 'sinatra'
require 'sinatra/activerecord'

set :database_file, "../../config/database.yml"

raises /home/username/.rvm/gems/ruby-2.1.5/gems/sinatra-activerecord-2.0.3/lib/sinatra/activerecord.rb:32:in database_file=: private method 'load' called for Psych:Module (NoMethodError) .

I tried to rollback to previous Gemfile.lock version, but error persisits.
What should be my next steps?

Answer 1

Setting

set :database, {adapter: 'postgresql', database: '_your_database_name_' }

instead of

set :database_file, "../../config/database.yml"

helps, but I'm still not sure where the bug came from.
