Modis

ActiveModel + Redis with the aim to mimic ActiveRecord where possible.

Requirements

Modis 4.0+ supports Rails 5.2 and higher, including Rails 6.1, as well as Ruby 2.3 and above, including Ruby 3.0. Tests are also being run with JRuby. For details please check the current CI setup.

For releases supporting older Rails versions such as 4.2-5.1 please check out the 3.x releases.

Installation

Add this line to your application's Gemfile:

gem 'modis'

And then execute:

$ bundle

Or install it yourself as:

$ gem install modis

Usage

class MyModel
  include Modis::Model
  attribute :name, :string
  attribute :age, :integer
end

MyModel.create!(name: 'Ian', age: 28)

all index

Modis, by default, creates an all index in redis in which it stores all the IDs for records created. As a result, a large amount of memory will be consumed if many ids are stored. The all index functionality can be turned off by using enable_all_index

class MyModel
  include Modis::Model
  enable_all_index false
end

By disabling the all index functionality, the IDs of each record created won't be saved. As a side effect, using all finder method will raise a IndexError exception as we would not have enough information to fetch all records. See https://github.com/rpush/modis/pull/7 for more context.
