PracticalErrors

Make rails error messages more practical.

Installation

Add this line to your application's Gemfile:

gem 'practical_errors'

And then execute:

$ bundle

Or install it yourself as:

$ gem install practical_errors

Usage

Add include PracticalErrors::Practicable to your controller.

class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception

  include PracticalErrors::Practicable
end

And then, error message will be like this:

ActiveRecord::RecordNotFound (
========== Practical Errors appends message from here ==========

Rails says, "Couldn't find Post with 'id'=1000".

You might have called ActiveRecord::FinderMethods#find, but the record for provided id was not found.
If you DO NOT want to raise ActiveRecord::RecordNotFound even if the record was not found,
you should use ActiveRecord::FinderMethods#find_by instead.

Post.find(1000) # raise ActiveRecord::RecordNotFound
Post.find_by(id: 1000) # just returns nill

Supported error list

• ActiveRecord::RecordNotFound

Do you think that there is little error that support? Please add !! (I will continue to increase supported errors, of course.)

Dependency

• Rails '>= 4.0.0', '< 5.0'
• error_arranger '0.1.0'

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
