# RomSqlGraph

[Rom-rb](http://rom-rb.org) and [hanami](http://hanamirb.org) tool for generating db (sql) association graph.

**For generating image you need to install graphviz tool (http://www.graphviz.org)**

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'rom_sql_graph'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install rom_sql_graph

## Usage

```ruby
# First: create rom repository object
repo = UserRepository.new

# Second: create Rom::Sql::Graph object
graph = RomSqlGraph.generate(repo)

# Generate image or html file with your db associations
graph.generate_image
graph.generate_html

# convert graph to any type
graph.to_a
graph.to_s
graph.to_json
```
