Module: Rails::Mongoid

create_indexes(pattern) click to toggle source

Create indexes for each model given the provided pattern and the class is not embedded.

@example Create all the indexes.

Rails::Mongoid.create_indexes("app/models/**/*.rb")

@param [ String ] pattern The file matching pattern.

@return [ Array<String> ] The file names.

@since 2.1.0

# File lib/rails/mongoid.rb, line 16
def create_indexes(pattern)
  logger = Logger.new($stdout)
  models(pattern).each do |model|
    next if model.index_options.empty?
    unless model.embedded?
      model.create_indexes
      logger.info("MONGOID: Created indexes on #{model}:")
      model.index_options.each_pair do |index, options|
        logger.info("MONGOID: Index: #{index}, Options: #{options}")
      end
    else
      logger.info("MONGOID: Index ignored on: #{model}, please define in the root model.")
    end
  end
end

load_models(app) click to toggle source

Use the application configuration to get every model and require it, so that indexing and inheritance work in both development and production with the same results.

@example Load all the application models.

Rails::Mongoid.load_models(app)

@param [ Application ] app The rails application.

# File lib/rails/mongoid.rb, line 85
def load_models(app)
  app.config.paths["app/models"].each do |path|
    preload = ::Mongoid.preload_models
    if preload.resizable?
      files = preload.map { |model| "#{path}/#{model}.rb" }
    else
      files = Dir.glob("#{path}/**/*.rb")
    end

    files.sort.each do |file|
      load_model(file.gsub("#{path}/" , "").gsub(".rb", ""))
    end
  end
end

models(pattern) click to toggle source

Return all models matching the pattern.

@example Return all models.

Rails::Mongoid.models("app/models/**/*.rb")

@param [ String ] pattern The file matching pattern.

@return [ Array<Class> ] The models.

# File lib/rails/mongoid.rb, line 62
def models(pattern)
  Dir.glob(pattern).map do |file|
    logger = Logger.new($stdout)
    begin
      determine_model(file, logger)
    rescue => e
      logger.error(%{MONGOID: Failed to determine model from #{file}:
        #{e.class}:#{e.message}
        #{e.backtrace.join("\n")}
      })
      nil
    end
  end.flatten.compact
end

preload_models(app) click to toggle source

Conditionally calls `Rails::Mongoid.load_models(app)` if the `::Mongoid.preload_models` is `true`.

@param [ Application ] app The rails application.

# File lib/rails/mongoid.rb, line 104
def preload_models(app)
  load_models(app) if ::Mongoid.preload_models
end

remove_indexes(pattern) click to toggle source

Remove indexes for each model given the provided pattern and the class is not embedded.

@example Remove all the indexes.

Rails::Mongoid.create_indexes("app/models/**/*.rb")

@param [ String ] pattern The file matching pattern.

@return [ Array<String> ] The file names.

# File lib/rails/mongoid.rb, line 42
def remove_indexes(pattern)
  logger = Logger.new($stdout)
  models(pattern).each do |model|
    next if model.embedded?
    indexes = model.collection.indexes.map{ |doc| doc["name"] }
    indexes.delete_one("_id_")
    model.remove_indexes
    logger.info("MONGOID: Removing indexes on: #{model} for: #{indexes.join(', ')}.")
  end
end
