This is a tool for generating the same xcdatamodeld files that XCode does when designing a datamodel for Core Data. It is written in pure ruby, but it will be of particular interest to RubyMotion developers.
Add this line to your application's Gemfile:
gem 'ruby-xcdm'
And then execute:
$ bundle
Or install it yourself as:
$ gem install ruby-xcdm
- Make a directory to hold your schemas (a.k.a. data model in XCode parlance)
- Create one schema version per file within the directory
- Run the command to generate a datamodel:
xcdm MyApplicationName schemadir datamodeldestdir
Here's a sample schema file:
schema "0.0.1" do
entity "Article" do
string :body, optional: false
integer32 :length
boolean :published, default: false
datetime :publishedAt, default: false
string :title, optional: false
has_one :author
end
entity "Author" do
float :fee
string :name, optional: false
has_many :articles
end
end
It's pretty self-explanatory. All the built-in data types are supported, and inverse relationships are generated automatically. If you need to set some of the more esoteric options on properties or relationships, you can include the raw parameters, like renamingIdentifier or defaultValueString.
