# rails-db-proxy

A better approach for using a primary and secondary database setup in

Rails.

### Design

The idea is that this library would manage the connections based on the

existing database YAML file with minimum changes and remain compatible

with the base ActiveRecord implementation. Here is the proposed changes

to the `database.yml` file.

```yaml

production:

  adapter: mysql2

  username: user

  password: super_s3cret

  host: my-db-host.domain.internal

  connections:

    primary: my-db-host.domain.internal

    secondary: my-secondary-db-host.domain.internal

```

### Usage examples

Model chaining

```rb

User.find(1).using_database_connection(:secondary)

```

For the whole model

```rb

class User < ActiveRecord::Base

  use_database_connection :secondary

end

```

...Or individual methods

```rb

# For only a certain methods

class User < ActiveRecord::Base

  use_database_connection :secondary, :only => [:get_all_users]

end

# For all methods in a model except for a subset of them

class User < ActiveRecord::Base

  use_database_connection :secondary, :except => [:quick_method]

end

```
