You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: fieldable_date_helpers.rb
    path of file: ./repos/binda/app/models/concerns/binda/fieldable_association_helpers
    
    the code of the file until where you have to start completion: module Binda
	module FieldableAssociationHelpers
		module FieldableDateHelpers
			# Check if the field has an attached date
			# 
			# @param field_slug [string] The slug of the field setting
			# @return [datetime] The date
			# @return [boolean] Reutrn false if nothing is found
			def has_date(f
    
			def has_date(field_slug)
				obj = self.dates.find{ |t| t.field_setting_id == FieldSetting.get_id( field_slug ) }
				raise ArgumentError, "There isn't any date associated to the current slug (#{field_slug}) on instance (#{self.class.name} ##{self.id}).", caller if obj.nil?
				if obj.present?
					return !obj.date.nil?
				else
					return false
				end
