问题 I stumbled to learn that my rails3.1 log file is super large, around 21mb. Is this, in terms of size normal? What the log file would like in the production environment? Besides, can I get rid of the log?thanks 回答1: you can just delete the file! Rails will create a new log if one doesn't exist. Obviously save / backup the file if it's important, but usually it's not. You can also zip the backuped up file (and then delete the source) if you want to keep it on the same drive but still save space

问题 I'm in the process of adding Devise to an existing Rails app, with a Users table already defined. The devise generator pushed out the following migration: class AddDeviseToUsers < ActiveRecord::Migration def self.up change_table(:users) do |t| ## Database authenticatable t.string :email, :null => false, :default => "" t.string :encrypted_password, :null => false, :default => "" ## Recoverable t.string :reset_password_token t.datetime :reset_password_sent_at ## Rememberable t.datetime

问题 Every time I push my app to heroku I see the line -----> Launching... done, v43 Is there a way to make that version number apear within the app so other people can see that number? 回答1: Why would you want to depend on running a command after every push?

Instead add to your Gemfile: gem 'heroku-api' Add your App name and API key to the Heroku config: $ heroku config:add HEROKU_APP_NAME=myapp HEROKU_API_KEY=bp6ef3a9... Then put

问题 I am using devise for my users. I recently installed the rails Active Admin gem, everything is working beautifully. However I can't figure out how to add a new admin users. I can see that active admin created an admin_user table in the db with a user admin@example.com, which I use to log in to the interface. I tried adding admin_user as a resource so that I can just click the Add Admin User button within the active admin interface to add a new user, however that does not seem to work. 回答1:

问题 I have 3 models called Price, UnitPrice and Purchase. The Price and UnitPrice models have an attribute called amount that I'm trying to scope to and get the total sum of both combined. I created two scopes, one for the total sum of both models. The other scope is to get the date attribute of both model's date fields. I'm trying to do this: <%= number_to_currency(current_user.purchases.today.total) But get the error: NoMethodError in pages#home undefined method `today' for #<ActiveRecord:

问题 OK - I'm in way over my head here. I'm using: - ruby-1.9.3-p0 - rails-3.1.3 - mail-2.3.0 - devise-1.5.3 Trying to turn on Devise's :confirmable option and start up smtp services in my app. As soon as I add /config/initializers/setup_mail.rb , add Devise's necessary columns in my DB, and the :confirmable attribute to my User model, I get a segmentation fault. It occurs right after a user signs up. Devise is trying to send out the confirmation email, causing the ruby smtp library to crash with

问题 I just installed rvm and upgraded ruby from 1.8.7 to 1.9.2 using rvm. I ran bundle install on my app, which re-installed my gems.
