# acts_as_nosql
This gem allows to handle JSON and JSONB fields as if they are proper database columns, handling default values, type casting and simplifying validation.
## Installation
Add the gem to your Gemfile
```ruby
gem 'acts_as_nosql'
```
## Example usage
```ruby
class User < ApplicationRecord
acts_as_nosql field_name: :data
# You can define multiple attributes at once with the same type
nosql_attrs :first_name, :last_name, type: :String
# You can set the default value
nosql_attr :age, type: :Integer, default: 0
# You can also pass a :path attribute
# This is used to decide how to write the attribute as a nested object
# In this example, `google_oauth_token` will be written in the JSON object as:
# `"oauth" => { "google_token" => __VALUE__ }`
nosql_attr :google_oauth_token, type: :String, path: [:oauth, :google_token]
# You can run standard ActiveRecord validations on these fields
validates :first_name, :last_name, presence: true
end
user = User.new
# You can use attributes as standard
user.first_name = 'John'
user.last_name 'Doe'
# This picks the default value
user.age # => 0
# This is stored as a nested object
user.google_oauth_token = 'xxxxxxx'
user.save!
# All attributes are stored in the `data` column
user.data # => { "first_name" => "John", "last_name" => "Doe", "age" => 0, "oauth" => { "google_token" => "xxxxxxx" }}
# You can also run basic queries:
User.where(first_name: 'John').to_sql # => SELECT "users".* FROM "users" WHERE "users"."data"->>"first_name" = 'John'
```
## TODO
* Complex querying (`group`, `pluck`, etc...)
* Issue the arrays mutation bug
