问题 I thought I understood how Bundler works with gems, but after something that recently happened, I am not sure I have it right. I am developing an Rails application. To start off (and just so I would get familiar with the Rails environment which I haven't worked in before), I did not use an IDE. But, because I'm missing out on some of the advantages of an IDE, I just started using RubyMine. As part of the RubyMine setup, it asked to update all my gems for my existing project. After that, I

问题 Hello I have a strange problem, I'm trying to get rake task working in whenever, but have this problem Could not find rake-10.4.2 in any of the sources (Bundler::GemNotFound) . It's strange, because it searches this rake version in ruby 2.1.2 version /home/vyivrain/.rvm/rubies/ruby-2.1.2/lib/ruby/gems/2.1.0/gems/bundler-1.6.2/lib/bundler/spec_set.rb:92 . However I'm using ruby 2.2.0 in rvm and the gem list is also using that version. It's a simple cron job: every 1.minute do rake 'process

问题 I'm porting an app into rails and a couple of the columns are named things like 2nd_phone 2nd_address When I try doing a migration using t.string :2nd_phone I get syntax error, unexpected tINTEGER, expecting tSTRING_CONTENT or tSTRING_DBEG or tSTRING_DVAR or tSTRING_END Any ideas how to do this in rals? 回答1: In your migration file have this with quotes to support starting character as numeric one and then run rake db:migrate t.string :'2nd_phone' While doing this way if you want to create new

问题 How do i find out if the database exists from within a rake task? that is, i'd like to do something like: task :drop_and_create => :environment do Rails.env = "development" if (db_exists?) Rake::Task["db:drop"].invoke end Rake::Task["db:create"].invoke #more stuff... end how do i write the db_exists? condition? 回答1: How about instead doing a begin/rescue: task :drop_and_create => :environment do Rails.env = "development" if (db_exists?) begin Rake::Task["db:drop"].invoke rescue Exception => e

问题 rails newbie here. I'm working through the tutorial on railstutorial.org on a Ubuntu 14.04 virtual machine. It's been pretty smooth sailing up until I got to heroku. When I want to push my app to heroku, it complains that it could not find rake-10.3.2. I checked heroku, and the application seems to be empty. However, I have rake-10.3.2 in my application, and if use "bundle show rake", it shows the correct version. brandon@brandon-virtualbox:~/rails_projects/first_app$ bundle show rake /home

问题 I want to call a rake task from a cron job that stores remote weather data in the rails cache. However, I must be doing something pretty wrong here because I cannot find any solution through countless fruitless searches. Say I define and call this task namespace :weather do desc "Store weather from remote source to cache" task :cache do Rails.cache.write('weather_data', Date.today) end end I get the error Anonymous modules have no name to be referenced by Which leads me to believe the rails

问题 I'm not sure how to deploy an application using Capistrano but I figured I'd try to at least load all the files I need on my deployment server, so I did a git pull on Github and installed all the dependencies using bundle install. I have RVM 1.6.32 running in Ruby 1.9.2p180 with Rails 3.0.9 and when I run rake db:migrate, I get rake aborted! Don't know how to build task 'db:migrate' I don't have the double semi-colon issue that other SO users have mentioned, so I'm genuinely confused. I have

问题 I have a collection of parsers that differ significantly in logic, but have the exact same methods and outputs. I have devised somewhat of a master Rake and I am curious if what I have come up with could lead to some unexpected or weird behavior. Essentially my parse.rake looks something like: require 'app/models/provider' require 'config/environment.rb' Provider.all.each do |provider| require "lib/tasks/#{provider.name}.rb" Kernel.const_get(provider.name).provider = provider namespace

问题 I'm calling a rake task within a task and I'm running into a roadblock when it comes to calling execute response = Rake::Task["stuff:sample"].execute[:match => "HELLO"] or response = Rake::Task["stuff:sample"].execute[:match => "HELLO",:freq=>'100'] Calling task task :sample, [:match,:freq] => :environment do |t, args| The error I get back is 'can't convert Hash into Integer' Any ideas? 回答1: I think the problem is in code you're not posting. Works fine for me: james@James-Moores-iMac:/tmp$

问题 The official documentation indicates that I should be able to build documentation for my application using rake doc:app , but when I run the command in Rails 5 I get the following output: bwerth@bwerth-VirtualBox:~/rails/gep$ rake doc:app rake aborted! Don't know how to build task 'doc:app' (see --tasks) (See full trace by running task with --trace) 回答1: This functionality was removed from Rails in version 5 with the following justification: ...In our experience applications do not generate
