问题 Problem: I have a Rails app which generates a pdf via the rails-latex gem. It works just fine on rails s and heroku local .

问题 I just looked at some tutorials Ruby on Rails, and I noticed that they use a lot of code on the command line, but do not feel comfortable with it only when it comes to database, my question is: There are tools you can use it visually ? ps: for my applications I want to use MySQL 回答1: MySQL has a free application with a GUI interface to MySQL: http://dev.mysql.com/downloads/tools/workbench/ If you're willing to pay, the best GUI app I've used is SQLyog: https://www.webyog.com/ 回答2: the best

问题 I have a JSONB column that holds the business hours of a store . As seen below, it doesn't seem to maintain the order in which it was inputted (sunday opens/closes at, monday opens/closes at). I wanted to iterate over the days of the week to produce results by day, and use the day to look up the respective #{day}_opens_at time to display. But I'm unsure how to do this using the loops index. Rather than sunday 09:00:00 - 18:00:00 , it prints out all of the hours: sunday 08:00:00 09:00:00 20:00

问题 Is there a way to specify order of execution inside cucumber? For example, rather than running cucumber feature/foo/foo.feature feature/foo/bar.feature to have those execute in that order... I want to run bundle exec cucumber and run in that specified order. I know that features/scenarios should be independent of each other but for the current tests I'm running it's not practical. If there is no "official way" (which seems to be the case) does anyone recommend a good design to implement such

问题 I picked up a 4 year old project written in Ruby 2.1.3 and Rails 4.1.8 . Very few of the gems were versioned but I've managed to get the project running locally by installing mysql2 0.3.20 as suggested in multiple other threads. Doing this required me to (on MacOS) downgrade openssl and mysql with brew install mysql@57 and brew install openssl@10 . I could then install mysql2 with by passing the correct libraries to it: gem install mysql2 -v 0.3.20 -- --with-mysql-config=/usr/local/opt/mysql
