## Installation

### Install as a standalone project

Use the installer:

```shell
$ gem install alchemy_cms --pre
$ alchemy new my_magicpage
```

and follow the instructions to finish the installation.

The installer has some options (like choosing the database). See them with:

```shell
$ alchemy --help
```

### Install into an existing Rails project

#### 1. Add the Alchemy gem:

Put this into your `Gemfile`:

```ruby
gem 'alchemy_cms', github: 'AlchemyCMS/alchemy_cms', branch: '3.5-stable'
```

If you want to use Russian translation and have better i18n support, you should put:

```ruby
gem 'russian', '~> 0.6.0'
```

or gem with similar functionality into your Gemfile.

#### 2. Update your bundle:

```shell
$ bundle install
```

#### 3. Set the authentication user

Now you have to decide, if you want to use your own user model or if you want to use
the Devise based user model that Alchemy provides and was extracted [into its own gem](https://github.com/AlchemyCMS/alchemy-devise).

##### Use Alchemy user

If you don't have your own user class, you can use the Alchemy user model. Just add the following gem into your `Gemfile`:

```ruby
gem 'alchemy-devise', github: 'AlchemyCMS/alchemy-devise', branch: '3.5-stable'
```

Then run:

```shell
$ bundle install
$ bin/rake alchemy_devise:install:migrations
```

##### Use your User model

In order to use your own user model you need to tell Alchemy about it.

The best practice is to use an initializer:

```ruby
# config/initializers/alchemy.rb
Alchemy.user_class_name     = 'YourUserClass'       # Defaults to 'User'
Alchemy.current_user_method = 'current_admin_user'  # Defaults to 'current_user'
Alchemy.signup_path         = '/your/signup/path'   # Defaults to '/signup'
Alchemy.login_path          = '/your/login/path'    # Defaults to '/login'
Alchemy.logout_path         = '/your/logout/path'   # Defaults to '/logout'
```

The only thing Alchemy needs to know from your user class is the `alchemy_roles` method.

This method has to return an `Array` (or `ActiveRecord::Relation`) with at least one of the following roles: `member`, `author`, `editor`, `admin`.

##### Example

```ruby
# app/models/user.rb

def alchemy_roles
  if admin?
    %w(admin)
  end
end
```

Please follow [this guide](http://guides.alchemy-cms.com/stable/custom_authentication.html) for further instructions on how to customize your user class even more.

#### 4. Install Alchemy into your app:

**After** you set the user model you need to run the Alchemy install task:

```shell
$ bin/rake alchemy:install
```

Now everything should be set up and you should be able to visit the Alchemy Dashboard at:

<http://localhost:3000/admin>

*) Use your custom path if you mounted Alchemy at something else then `'/'`


## Customizing

Alchemy has very flexible ways to organize and manage content. Please be sure to read [the introduction guide](http://guides.alchemy-cms.com/stable/index.html) in order to understand the basic idea of how Alchemy works.


### Custom Controllers

Beginning with Alchemy 3.1 we do not patch the `ApplicationController` anymore. If you have controllers that loads Alchemy content or uses Alchemy helpers in the views (i.e. `render_navigation` or `render_elements`) you can either inherit from `Alchemy::BaseController` or you `include Alchemy::ControllerActions` in your controller (**that's the recommended way**).

### Custom admin interface routing

By default, Alchemy Dashboard is accessible at <http://example.com/admin>. You can change this by setting `Alchemy.admin_path` and `Alchemy.admin_constraints`.
For example, these settings:

```ruby
# config/initializers/alchemy.rb

Alchemy.admin_path = '/backend'
Alchemy.admin_constraints = {subdomain: 'hidden'}
```

will move the dashboard to <http://hidden.example.com/backend>.

### Picture caching

Alchemy uses the Dragonfly gem to render pictures on-the-fly.

To make this as performant as possible the rendered picture gets stored into `public/pictures`
so the web server can pick up the file and serve it without hitting the Rails process at all.

This may or may not what you want. Especially for multi server setups you eventually want to use
something like S3.

Please follow the guidelines about picture caching on the Dragonfly homepage for further instructions:

http://markevans.github.io/dragonfly/cache/


## Upgrading

The Alchemy team takes upgrades very seriously and tries to make them as smooth as we can.
Therefore we have build in upgrade tasks, that try to automate as much as possible.

That's why after updating the Alchemy gem you should **always run the upgrader**:

```shell
$ bundle update alchemy_cms
$ bin/rake alchemy:upgrade
```

Alchemy will print out useful information after running the automated tasks that help a smooth upgrade path.
So please **take your time and read them**.

Always be sure to keep an eye on the `config/alchemy/config.yml.defaults` file and update your `config/alchemy/config.yml` accordingly.

Also, `git diff` is your friend.

### Customize the upgrade preparation

The Alchemy upgrader comes prepared with with several rake tasks in a specific order.
This is sometimes not what you want or could even break upgrades.
In order to customize the upgrade preparation process you can instead run each of the tasks on their own.

```shell
$ bin/rake alchemy:install:migrations
$ bin/rake db:migrate
$ bin/rake alchemy:db:seed
$ bin/rake alchemy:upgrade:config
$ bin/rake alchemy:upgrade:run
```

**WARNING:** This is only recommended, if you have problems with the default `rake alchemy:upgrade` task and need to
repair your data in between. The upgrader depends on these upgrade tasks running in this specific order, otherwise
we can't ensure smooth upgrades for you.

### Run an individual upgrade

You can also run an individual upgrade on its own:

```shell
$ bin/rake -T alchemy:upgrade
```

provides you with a list of each upgrade you can run individually.

#### Example

```shell
$ bin/rake alchemy:upgrade:3.2
```

runs only the Alchemy 3.2 upgrade

## Deployment

Alchemy has an official Capistrano extension which takes care of everything you need to deploy an Alchemy site.

Please use https://github.com/AlchemyCMS/capistrano-alchemy, if you want to deploy with Capistrano.

### Without Capistrano

If you don't use Capistrano you have to **make sure** that the `uploads`, `tmp/cache/assets`, `public/assets` and `public/pictures` folders get **shared between deployments**, otherwise you **will loose data**. No, not really, but you know, just keep them in sync.


## Testing

If you want to contribute to Alchemy ([and we encourage you to do so](https://github.com/AlchemyCMS/alchemy_cms/blob/master/CONTRIBUTING.md)) we have a strong test suite that helps you to not break anything.

### Preparation

First of all you need to clone your fork to your local development machine. Then you need to install the dependencies with bundler.

```shell
$ bundle install
```

To prepare the tests of your Alchemy fork please make sure to run the preparation task:

```shell
$ bundle exec rake alchemy:spec:prepare
```

to set up the database for testing.

### Run your tests with:

```shell
$ bundle exec rspec
```

**Alternatively** you can just run*:

```shell
$ bundle exec rake
```

*) This default task executes the database preparations and runs all defined test cases.

### Start the dummy app

You can even start the dummy app and use it to manually test your changes with:

```shell
$ cd spec/dummy
$ bin/rake db:setup
$ bin/rails s
```

**A note about RSpec version:**

Alchemy specs are written **in RSpec 3**. Please **do not use deprecated RSpec 2.x syntax**. Thanks
