# Db Serializer

This gem provide a blazing fast way to serialize Active Record models.
At the moment only a GeoJSON serializer is implemented

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'db_serializer'
```

And then execute:

```bash
$ bundle install
```

Then you need to include the concern `DbSerializer::GeoJSON` to your model:

```ruby
# In this example the City model has:
# - an attribute name of type string
# - an attribute boundaries of type geometry
class City < ActiveRecord::Base
# Include this concern
include DbSerializer::JSON

# Specify which column contains the geometry
# If you don't specify it, by default it will be :geometry
db_serializer :boundaries
end
```

## Usage

```ruby
puts City.all.to_geojson([:id, :name])

# If you had such a model, it would output something like this:
# {
# "type": "FeatureCollection", "features": [{
# "id": 1, "type": "Feature", "geometry": {
# "type": "MultiLineString", "coordinates": [[[x1,y1],[x2,y2]]]
# },
# "properties": {"id": 1, "name": "Paris"}
# }]
# }
```
Note: the output has been pretty printed for readability but please keep in mind that `to_geojson` returns a *string* containing a valid serialized JSON.
It means that you do not need to use `to_json` on it and that it can be parse with `JSON.parse`.

## Development

After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake test` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
