class Decidim::Meetings::FilteredMeetings

A class used to find meetings filtered by components and a date range

def self.for(components, start_at = nil, end_at = nil)

end_at - A date to filter resources created before it.
start_at - A date to filter resources created after it
components - An array of Decidim::Component

Syntactic sugar to initialize the class and return the queried objects. 
def self.for(components, start_at = nil, end_at = nil)
  new(components, start_at, end_at).query
end

def initialize(components, start_at = nil, end_at = nil)

end_at - A date to filter resources created before it.
start_at - A date to filter resources created after it
components - An array of Decidim::Component

Initializes the class. 
def initialize(components, start_at = nil, end_at = nil)
  @components = components
  @start_at = start_at
  @end_at = end_at
end

def query

by a range of dates.
Finds the Projects scoped to an array of components and filtered 
def query
  meetings = Decidim::Meetings::Meeting.where(component: @components)
  meetings = meetings.where("created_at >= ?", @start_at) if @start_at.present?
  meetings = meetings.where("created_at <= ?", @end_at) if @end_at.present?
  meetings
end
