SnakyParams

SnakyParams is Rack middleware for Rails that automatically converts request parameter keys to snake_case.

This is useful if you Rails app is being used as an API for a front-end application written in any other language (e.g. JavaScript). In Ruby and Rails, the widely adopted naming convention is to use snake_case for variables, keys etc. Popular JavaScript style guides (such as the Airbnb JavaScript Style Guide) tend to recommend camelCase. This gem allows you to use snake_case in all Ruby/Rails code without having to worry about converting the case of parameter names or having non-conventional names.

1. Add this line to your application's Gemfile and execute bundle install:

gem 'snaky_params'

2. Add this line as the last config to config/application.rb:

config.middleware.use SnakyParams::Middleware

Conversion is automatic. All query, post, put and patch parameter keys in requests to your Rails application are converted to snake_case.

Example:

• searchQuery becomes search_query
• FirstName becomes first_name
• last-name becomes last_name
• monthlyOrYearlySalary becomes monthly_or_yearly_salary
