由 风格不统一 提交于 2019-12-17 07:15:53
问题 Earlier it was working fine. I have been playing little bit config. So may be i have changed some config unknowingly. here is config of environment/development.rb config.cache_classes = false # Log error messages when you accidentally call methods on nil. config.whiny_nils = true # Show full error reports and disable caching config.consider_all_requests_local = true config.action_view.debug_rjs = true config.action_controller.perform_caching = false # Don't care if the mailer can't send

Init some variables when opening rails console

由 筅森魡賤 提交于 2019-12-11 14:48:47
问题 Here's the thing. I use quite a lot the console to test my methods before plugging them in my app (nothing new here I guess). What I'd find convenient, would be to have like a console_seed.rb file that I would load and then all my variables are ready for use. Ex: console_seed.rb me = User.find(77) other_person = User.find(89) So I can immediately test: me.add_friend(other_person) when opening the console, without having to write the .find() lines again and again. I found this post : how can I

Heroku pipeline. Run commands on production app (not staging)

由 房东的猫 提交于 2019-12-11 07:30:22
问题 I am using the heroku pipeline. I set up my two apps. One for staging, one for production. Both use "production" as the environment variable. If I run heroku run rails c I can access the console on my staging app. The heroku website, allows to run a console in the production app as well, but only with the predifined heroku run part. Which means if for whatever reason I need to run a more fundamental command (for example heroku pg:reset ; I know I know), I can't. So is there a way to specify

问题 Let's say I wanted a greeting every time the Rails console comes up: Scotts-MBP-4:ucode scott$ rails c Loading development environment (Rails 4.2.1) Hello there! I'm a custom greeting 2.1.5 :001 > Where would I put the puts 'Hello there! I\'m a custom greeting' statement? Another Stackoverflow answer suggested, and I've read this elsewhere too, that I can put that in an initializer like this: # config/initializers/console_greeting.rb if defined?(Rails::Console) puts 'Hello there! I\'m a

Ruby on Rails: Data not saving ActiveRecord

问题 I'm pretty new to Ruby on Rails and I've been trying to develop a simple blog. However when I try to save the new Post, the page reloads a new page and no data is saved. The data however is present in the URI. Here's my controller: class PostsController < ApplicationController before_action :set_post, only: [:show, :edit, :update, :destroy] # GET /posts # GET /posts.json def index @posts = Post.all end # GET /posts/1 # GET /posts/1.json def show end # GET /posts/new def new @post = Post.new

Rails console (END) how to get past it?

由 随声附和 提交于 2019-12-07 01:37:12
问题 working in the Rails console, I pasted a very long hash into the console and when I scrolled ot the bottom of it it has the token (END) but the only way I've found to get past it is to exit the console with CTRL+Z. This defeats my purpose in using the console for testing some code out. Is there any other way to get past that (END) token? 回答1: stumbled over this problem, after some tries I found the solution :) ⇧ shift + Q Edit: as mentioned by @Paul, only Q will suffice. 回答2: What about Ctrl

'You do not have access to the app' when trying to access heroku console

由 こ雲淡風輕ζ 提交于 2019-12-06 17:30:39
问题 I recently started collaborating in a project on Heroku using Ruby on Rails. I was added as a collaborator and added the remote to my environment. After some development, I pushed some changes and had no problems: $ git push staging Where staging is the name of my remote. Later, when trying to run "rake test" on Heroku, I recieved an error: $heroku run rake test --app staging Running `rake test` attached to terminal... failed ! You do not have access to the app staging. Which is odd, as I was

Rails 3 Sandbox Console

由 好久不见. 提交于 2019-12-05 12:52:35
问题 In Rails 2 you're able to run script/console --sandbox so you can play with production data and not accidentally break anything. I can't seem to find the equivalent command for Rails 3. Does anyone know what it is? 回答1: Easy, type in: bundle exec rails c -s and that is it. $ bundle exec rails c --help Usage: console [environment] [options] -s, --sandbox Rollback database modifications on exit. --debugger Enable ruby-debugging for the console. --irb DEPRECATED: Invoke `/your/choice/of/ruby
