# gtm_rails [![Build Status](https://travis-ci.org/koic/gtm_rails.svg)](https://travis-ci.org/koic/gtm_rails) [![Gem Version](https://badge.fury.io/rb/gtm_rails.svg)](http://badge.fury.io/rb/gtm_rails) [![git.legal](https://git.legal/projects/3929/badge.svg "Number of libraries approved")](https://git.legal/projects/3929)

Simply embed Google Tag Manager container snippet into Rails application.

## Installation

Add these lines to your application's Gemfile:

```
gem 'gtm_rails'
```

And then execute:

```
$ bundle
```

Or install it yourself as:

```
$ gem install gtm_rails
```

## Configuration

Create `config/google_tag_manager.yml` in your Rails application.

```yaml
staging:
  foo: GTM-YourGtmId1
  bar: GTM-YourGtmId2
  baz: GTM-YourGtmId3
production:
  foo: GTM-YourGtmId4
  bar: GTM-YourGtmId5
  baz: GTM-YourGtmId6
```

The above is a sample. `foo`, `bar`, `baz` are arbitrary label names, and replacing GTM-XXXX with your container ID.

In view, use two helper methods. (Click here to [read more](https://developers.google.com/tag-manager/quickstart))

First, following method as close to the opening `<head>` tag as possible on every page of your website.

```ruby
<%= google_tag_manager_script_tag(:foo) %>
```

Second, following method immediately after the opening `<body>` tag on every page of your website.

```ruby
<%= google_tag_manager_noscript_tag(:foo) %>
```

These method arguments are a label name specified in `config/google_tag_manager.yml`.

Google Tag Manager container snippet will be expanded based on `Rails.env` and label name. If there is no match, a blank string is returned.
