问题 I'm using Rails 3.2 and have a migration that contains the code: add_column :users, :gift_aid, :integer, :default => 2 # reset columns User.reset_column_information ... code here to load legacy data from sqlite3 database ... # now create a user with the loaded column data user = User.create( ...other cols..., :gift_aid => migrated_gift_aid_column_data, ...other cols... ) and I get unknown attribute: gift_aid when running the migration. User.column_names shows the same list before and after

问题 Why are some rake tasks not listed by rake -T ? Like db:migrate:reset ? I can execute it without a problem, but why is it not listed there? Is there a way to get a real full list of rake tasks? % rake -T (in /home/zeus/projects/my_project) rake about # List versions of all Rails frameworks and the environment rake db:create # Create the database from config/database.yml for the current Rails.env (use db:create:all to create all dbs in the config) rake db:drop # Drops the database for the

问题 I've written a rails app that follows the regular directory structure (model code in models, controller code in controllers). But I'm now working on a new feature and for that I have written some (what I would call) "service" code. The new feature is to import some data into the system, at the moment it's two classes to do the importing but could expand to more. I don't believe the new code belongs in model as it's not modelling any object (it's not directly related to any single object

问题 I'm using EventMachine and Monetarily to start e TCP server along with my rails application. This is started from config/initializers/momentarily.rb . My problem is that it starts also when I run rake tasks, like db:migrate . I only want it to start when when I start the HTTP server. Environments won't help, since both the server start and rake tasks are under Development environment. Is there a way of knowing that the application is running the HTTP server as opposed to anything else? Note

问题 My simple rake task, stored in lib/tasks/items_spider.rake runs just fine in development. All it does is call spider! on the Item model. namespace :items do desc "Spider the web for data, hoorah" task :spider => :environment do Item.spider! end end I have the :environment task as a dependency, so everything works just fine. However, when I add RAILS_ENV=production , I hit errors, both on my local server and the production server: $ rake items:spider RAILS_ENV=production --trace (in /home

问题 I have a rake task where I do some checks at the beginning, if one of the checks fails I would like to return early from the rake task, I don't want to execute any of the remaining code. I thought the solution would be to place a return where I wanted to return from the code but I get the following error unexpected return 回答1: A Rake task is basically a block. A block, except lambdas, doesn't support return but you can skip to the next statement using next which in a rake task has the same

问题 I am doing TDD/BDD in Ruby on Rails 3 with Rspec (2.11.0) and FactoryGirl (4.0.0). I have a factory for a Category model: FactoryGirl.define "Category" do factory :category do name "Foo" end end If I drop, create then migrate the database in the test enviroment I get this error: rake aborted! Could not find table 'categories' This problem occurs because FactoryGirl expects the tables to already exist (for some odd reason). If I remove the spec folder from my rails app and do db:migrate , it

问题 I am working through the Ruby on Rails 3 tutorial book and typed the following on the command line: rake db:migrate which produced the following warning.

问题 moved a rails app of mine onto a new server and had to install a few gem dependencies. However, after installing the mysql gem I get the error, uninitialized constant MysqlCompat::MysqlRes, whenever I try to run a rake command that involves the mysql database. It seems I only get this error when I require the mms2r gem. Has anyone ever heard of this? I'm running mysql 2.8.1 gem. 回答1: on my Mac OS X 10.6 I did this to install the 2.8.1 gem, which worked perfectly with my MacPorts mysql5-server
