# Activerecord::Cause
[![Build Status](https://travis-ci.org/joker1007/activerecord-cause.svg?branch=master)](https://travis-ci.org/joker1007/activerecord-cause)

This gem logs where ActiveRecord actually loads record

ex.
```
D, [2015-04-15T22:13:46.928908 #66812] DEBUG -- :   User Load (0.1ms)  SELECT "users".* FROM "users"
D, [2015-04-15T22:13:46.929038 #66812] DEBUG -- :   User Load (ActiveRecord::Cause)  caused by /Users/joker/srcs/activerecord-cause/spec/activerecord/cause_spec.rb:16:in `block (3 levels) in <top (required)>'
```

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'activerecord-cause'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install activerecord-cause

## Usage

```ruby
ActiveRecord::Cause.match_paths = [
  /spec\/spec_helper/,
] # default is []
ActiveRecord::Cause.log_with_sql = true # default is false
```
```ruby
# spec/spec_helper.rb
User.all

# output to log file.
# D, [2015-04-15T22:13:46.928908 #66812] DEBUG -- :   User Load (0.1ms)  SELECT "users".* FROM "users"
# D, [2015-04-15T22:13:46.929038 #66812] DEBUG -- :   User Load (ActiveRecord::Cause)  SELECT "users".* FROM "users" caused by /Users/joker/srcs/activerecord-cause/spec/activerecord/cause_spec.rb:16:in `block (3 levels) in <top (required)>'
```

on Rails, `Activerecord::Cause.match_paths` has default `[/#{Rails.root.join("app").to_s}/]`
