问题 I have a sinatra app with a Rakefile.rake and server.rb file. In the server.rb file I have get '/' do rake :test end the app loads up but crashes when I load localhost:4567/ and says undefined method 'rake' for sinatra application. I try and require the file by using require '/home/user/project/Rakefile' and I also try Rakefile.rake but both give me an error that reads "require cannot load such file." I'm using Ubuntu. I'm not sure why sinatra can't load the rakefile, but when I run rake test

问题 I have run into a very strange problem. I have a task which resets my database as so: task :reset => [:drop, :create, :migrate, :seed] The problem is, I am receiving errors when seeding because of missing columns which are added in late migration files. One example: undefined method new_attr= for User Yet this attribute is already added in a migration. The strange part is, I receive no errors if I run the above tasks separately. Can anybody shed some light? Surely these tasks cannot be run

问题 I have loaded the 'stanford-core-nlp' gem and am trying to use it in my fledgling app. However, every time I try to show the rendered text, I receive this error message from Chrome and the rails server exits, citing Trace/BPT trap: 5. I have searched other similar Rails errors but can't find anything that seems to match my situation. The only thing I can think of is that the code below is causing some kind of issue? def pos_tagger (text) require 'stanford-core-nlp' pipeline = StanfordCoreNLP

问题 I'm trying to test a post request with capybara and cucumber. I can't visit a page and press a link to send the request because it has a confirm dialogue and I haven't made it work with javascript so I'm trying to use the post method and then test if it redirects to the appropriated url but I'm getting: No response yet. Request a page first. (Rack::Test::Error) My code is: page.driver.post url page.driver.status_code.should be 302 follow_redirect! It's working fine until follow_redirect! . I

When I use 'bundle exec rake db:populate' this task is working fine. I have full db of User records. I also have some rspec tests, which are using model

问题 Per this question: Setting up rake-pipeline for use with handlebars alongside Google App Engine I'm using a MinispadeFilter as my dependency management system via rake-pipeline. The weird thing I'm seeing is the coffeescript and handlebars files have their minispade identifier set to a tmp directory (I'm assuming, where the work is being done). screencast.com/t/wIXmREcreW Is there a way to set that to a root path such that it is normalized? Likewise my js files, while not pointing to a tmp
