rake

问题 I have spent hours upon days trying to resolve this. Rake is throwing the following error: dcarpenter$ rake rake aborted! uninitialized constant ActionView::Helpers::JavaScriptProxy I can't seem to find anyone who has had this issue on Google, this site or elsewhere. What steps should I take to resolve this and what do I need to know? rake --trace yields: /Users/dcarpenter/Dropbox/workspace/gems/rake-0.9.2/lib/rake/ext/module.rb:36:in `const_missing' /Users/dcarpenter/Dropbox/workspace/gems

问题 Looked at this question already, and that more or less mirrors how I currently run my whole suite. Additionally, I've setup the following rake task: Rake::TestTask.new do |t| t.name = "spec:models" t.libs << "test" t.pattern = "spec/models/*_spec.rb" end But I notice when I run this using time rake spec:models , that it completes in about 2.36 seconds. If I run all the individual tests in that directory using ruby /path/to/spec.rb (all are isolated from ActiveRecord currently--no persistance

Using bundle exec may solve this. The error message implies that I can use bundle exec to solve the problem, but I am not sure how? So, how to get rid of this error message? ------------------------------ more --------------------------- I prefer to update my Gemfile

问题 I have a rake task that fetches JSON data from an API, parses it, and saves it to the database: task :embedly => :environment do require 'json' require 'uri' require 'open-uri' Video.all.each do |video| json_stream = open("http://api.embed.ly/1/oembed?key=08b652e6b3ea11e0ae3f4040d3dc5c07&url=#{video.video_url}&maxwidth=525") ruby_hash = JSON.parse(json_stream.read) thumbnail_url = ruby_hash['thumbnail_url'] embed_code = ruby_hash['html'] video.update_attributes(:thumbnail_url => thumbnail_url

问题 I'm just trying to get the most basic of basic shell of a rails app running under 3.1, and I'm getting this weird error when I run bundle exec rake db:migrate- Please install the mysql2 adapter: `gem install activerecord-mysql2-adapter` (can't activate mysql2 (~> 0.3.6), already activated mysql2-0.3.2.

问题 Within a rake task how does one query the description? Something that would give: desc "Populate DB" task populate: :environment do puts task.desc # "Populate DB" end 回答1: task must be defined as a parameter for the task-block. desc "Populate DB" task :populate do |task| puts task.comment # "Populate DB" puts task.full_comment # "Populate DB" puts task.name # "populate " end Edit: This solution works with rake 0.8.7. At least rake 0.9.2.2 need an additional Rake::TaskManager.record_task

问题 Is there any trivial way to copy the data from developmenet database into the test one? I know theres a way to copy schema and recreate database, but is there any rake task to populate test database with development one? 回答1: You can use mysql directly: mysqldump app_development | mysql app_test 回答2: You can use: rake db:test:clone To copy the development db into test. 回答3: For all databases: rake db:test:clone && rake db:seed RAILS_ENV='test' 回答4: If you just want to clone the development DB
