ModelRenamer

The model renamer gem allows you to rename any a model in your rails application. The gem looks for occurrences of any variation or pluralization of the old model name and changes it to the corresponding variation of the new name. It also generates database migrations that rename tables and foreign keys referencing the old name.

Add this line to your application's Gemfile:

gem 'model_renamer'

And then execute:

$ bundle

Or install it yourself as:

$ gem install model_renamer

Run rails console and use the following command:

Rename.new("OldName", "NewName").run

This will rename everything in the codebase as well as generate the migrations. If you only want to rename files and directories, run:

Rename.new("OldName", "NewName").rename_files_and_directories

To only rename within the contents of the files, run:

Rename.new("OldName", "NewName").rename_in_files

To only generate migrations, you guessed it:

Rename.new("OldName", "NewName").generate_migrations

You can pass in parameters to the constructor to specify paths to ignore and the root directory:

Rename.new("OldName", "NewName", ignore_paths: ['mailers/'], path: 'app/')

This will ignore any files within the mailers/ directory and search for OldName renames starting in the app/ directory. By default no paths are ignored and the path is the current directory.

These are the file types that renamer will search for: js, coffee, hamlc, skim, erb, sass, scss, css, rb, slim, haml, rabl, html, txt, feature, rake, json, sh, yaml, yml, sql, csv
