由 半世苍凉 提交于 2019-12-21 21:38:48
问题 I am using Ruby on Rails 3.1 and I would like to know how , when and why I should use one of the following code rather than another on internationalizing my application (I18n gem): t(:test_key) t('test_key') t('.test_key') That is, what is the "subtle" difference between using t(:test_key) , t('test_key') and t('.test_key') ?

Why does a single record lookup return an array? (Rails beginner)

由 我的梦境 提交于 2019-12-21 17:13:06
问题 I have a where operation on a model that returns a single object. But I can't seem to use it in object notation (it appears to return an array with the object at [0]). store = Store.where("some_id = ?", some_id) puts store.name # doesn't work puts store # shows array with the object at [0] 回答1: Because sometimes you don't know how many objects a query should return, so for consistency you always get an array. To get a single object use store = Store.where("some_id = ?", some_id).first If you

问题 I came across a problem where I was working on two branches on a rails project and each project has a migration to add a column. At the time, rake db:migrate:reset cause a problem and I solely relied on my schema.rb to correctly represent the state of my database. At one point, I came across a problem where a column added by branch A got into the schema of branch B. Since migrate:reset was not an option, I resorted to manually editing the schema file to. I committed this change that basically

How can I keep my initializer configuration from being lost in development mode?

由 时光总嘲笑我的痴心妄想 提交于 2019-12-21 06:57:32
问题 I'm working on a Rails app that uses an engine. I'm using an initializer to configure one of my engine's controllers so that it will trigger an action in the host app. The code looks something like this: # config/initializers/my_engine.rb MyEngine::SomeController.after_filter proc { # Do something in the host app }, :only => :update This works fine in production, but in development mode, the proc is only called on the first request. This is because the classes are getting reloaded and this
