Finding all documents in a collection with Mongoid

mongodb, mongoid, ruby

Solution

`Category` indeed doesn't have a method `each` because it's a model class, not a collection. It has, however, several methods that do return collection-like objects. One of them is `all`. So the code should look like this:

Category.all.each do |test|
  puts test.inspect
end

Problem

I have been fiddling with Mongo, but can't get this simple example to work. I'm simply trying to retrieve all documents in a collection: ``` require 'mongoid' # configuration ... class Category include Mongoid::Document field :name, type: String end Category.each do |test| puts test.inspect end ``` I get the error: `undefined method 'each' for Category:Class (NoMethodError).` Connection to the database is well established, and a collection named `categories` contains a few documents.
