# SeedSortToolkit

`SeedSortToolkit` is rails seed file sort tool.  
This tool can without changing the content & format, just replace only order.

### note:   
If you use `YAML.load` and sort and `YAML.dump`.  
The format of your seed, diff comes out a little.  

 For example: 
  - Quotes(`""`,`''`) for string will be disappears.
  - `nil` column will be blank.

This tool does not cause the above problem.

```ruby
