# PlainSerializer
[](https://badge.fury.io/rb/plain_serializer)
[](https://circleci.com/gh/djezzzl/plain_serializer/tree/master)
[](https://codeclimate.com/github/djezzzl/plain_serializer/maintainability)
The gem provides plain DSL to serialize objects of any kind.
It includes features such as:
- [Nested serialization](#nested-serialization)
- [Pre-defined groups](#pre-defined-groups)
- [Output modification](#output-modification)
- [Self serialization](#self-serialization)
Output is `Hash` object which means you can convert it easily to anything you want.
## Installation
Add this line to your application's Gemfile:
```ruby
gem 'plain_serializer'
```
And then execute:
$ bundle install
Or install it yourself as:
$ gem install plain_serializer
## Usage
Imagine you have an object which has few simple attributes, something like the following:
```ruby
user = OpenStruct.new(name: 'John Doe', age: 30)
```
You can define your serializer like:
```ruby
class UserSerializer < PlainSerializer::Base
define_attribute :name
define_attribute :age
end
```
When you need to serialize your object, you can do it as simple as this:
```ruby
serializer = UserSerializer.setup(:name, :age)
# for single object
p serializer.serialize(user)
# => {:name=>"John Doe", :age=>30}
# for collection of objects
p serializer.serialize_collection([user])
# => [{:name=>"John Doe", :age=>30}]
```
### Nested Serialization
```ruby
user = OpenStruct.new(
account: OpenStruct.new(name: 'USA'),
properties: [
OpenStruct.new(code: 'property1'),
OpenStruct.new(code: 'property2')
]
)
class PropertySerializer < PlainSerializer::Base
define_attribute :code
end
class AccountSerializer < PlainSerializer::Base
define_attribute :name
end
class UserSerializer < PlainSerializer::Base
define_serializer :account, AccountSerializer
define_collection_serializer :properties, PropertySerializer
end
serializer = UserSerializer.setup(account: :name, properties: :code)
p serializer.serialize(user)
# => {:account=>{:name=>"USA"}, :properties=>[{:code=>"property1"}, {:code=>"property2"}]}
```
### Pre-defined groups
```ruby
user = OpenStruct.new(
name: 'John Doe',
age: '30',
account: OpenStruct.new(name: 'USA')
)
class AccountSerializer < PlainSerializer::Base
define_attribute :name
end
class UserSerializer < PlainSerializer::Base
define_attribute :name
define_attribute :age
define_group :personal, [:age, account: :name]
define_serializer :account, AccountSerializer
end
serializer = UserSerializer.setup(:name, :personal)
p serializer.serialize(user)
# => {:name=>"John Doe", :age=>"30", :account=>{:name=>"USA"}}
```
### Output modification
```ruby
user = OpenStruct.new(name: 'John Doe')
class UserSerializer < PlainSerializer::Base
define_attribute :name
end
serializer = UserSerializer.setup(:name)
p(serializer.serialize(user) do |output|
output[:anything] = 'anything_you_want_here'
end)
# => {:name=>"John Doe", :anything=>"anything_you_want_here"}
```
### Self serialization
```ruby
user = OpenStruct.new(
birthday: DateTime.now
)
class DateTimeSerializer < PlainSerializer::Base
def serialize(entity)
entity.iso8601
end
end
class UserSerializer < PlainSerializer::Base
define_serializer :birthday, DateTimeSerializer
end
serializer = UserSerializer.setup(:birthday)
p serializer.serialize(user)
# => {:birthday=>"2020-05-17T11:46:40+02:00"}
p DateTimeSerializer.setup.serialize(DateTime.now)
# => "2020-05-17T11:46:40+02:00"
```
