Rails - Method to return if a merchant is open

Question

I have a Merchant model. The model accepts_nested_attributes for the Working Hour model.

Merchant Model

class Merchant < ApplicationRecord

  has_many   :working_hours, inverse_of: :merchant, dependent: :destroy

  accepts_nested_attributes_for :working_hours, reject_if: :all_blank, allow_destroy: true

end

Working Hour model

class WorkingHour < ApplicationRecord

  belongs_to :merchant 

end

The working_hours table has:

class CreateWorkingHours < ActiveRecord::Migration[5.0]

  def change

    create_table :working_hours do |t|

      t.integer :day

      t.time :open_time

      t.time :close_time

      t.references :merchant, foreign_key: true

      t.timestamps

    end

  end

end

The merchants can have more than one working_hour block by day
ex: 8:00 to 12:00 / 15:00 to 18:00.

I want to create a method to return if the merchant are opened or closed. How can I do that?

Answer 1

Update We've should've lost the self. part

try to add this to your merchant model

def open?
    self.working_hours.any? { |wh|
        (wh.open_time.hour..wh.close_time.hour).cover?(Time.current.hour)
    }
end
