## Installation

JTRailsToolbox is distributed as a gem, which is how it should be used in your app.

Create a `jt-toolbox.yml` file:

A simple configuration of `jt-toolbox.yml` file:

### http_accept_language

To install `http_accept_language` you just have to add a line in your `ApplicationController`

```ruby
class ApplicationController < ActionController::Base
  include HttpAcceptLanguage::AutoLocale

end
```

### Dotenv

It's a good practice to not include credentials for third party services in your code. You can defined it in a `.env` file which I recommend to not include in your git repository.

### Exception Notification

If `exception` is not set in `jt-toolbox.yml` file, Exception Notification is disabled.
In addition to the default ignored exceptions, the following exceptions are also muted:

- `ActionController::InvalidCrossOriginRequest`
- `ActionController::InvalidAuthenticityToken`

### Airbrake

If `airbrake` is not set in `jt-toolbox.yml` file, Airbrake is disabled.

### Paperclip

- `convert_options` is set to `-strip`, which means all metadata of images are removed, this is used for reduced the weight of images.
- `use_timestamp` is et to `false`, it's a good practice to have unique url for image and url without parameters, instead of using the timestamp we use the fingerprint of the image. [More informations here.](https://github.com/thoughtbot/paperclip#md5-checksum--fingerprint)
- the default fodler of images is `upload` (in public folder)

### Sidekiq

- configured for `ActiveJob`
- configured to send notification error with Exception Notification or Airbrake
- redis url is by default `redis://localhost:6379/0` and the namespace is `#{name of your application}` for production and `#{name of your application}-{environment}` for others.

#### Warning

Don't forget to install redis server and to launch sidekiq with:

```
bundle exec sidekiq -e $RAILS_ENV -q default -q mailers -d -L log/sidekiq.log -P tmp/pids/sidekiq.pid
```

### Hostname

- `host` is the hostname of your website, it's used for setting the host when you email
- `asset_host` is the hostname of the assets server. By default equal to `host`.
- `cdn_host` is the hostname for serving uploaded files with paperclip. By default equal to `asset_host`.

It's a good practice to have a different domains for your web server and your file server (search "Cookieless Domain" on google for more informations).

### ActionMailer

ActionMailer can be configured easily just with `jt-toolbox.yml` file.

### Helper methods

### google_anaytics_tag

It will add automatically in production environment the javascript code for Google Analytics.
You just have add at the end of your `app/views/layouts/application.html.erb` file:

```
<%= google_anaytics_tag 'UA-XXXXXXX-X' %>
```
