#available?Boolean

determine if product is available. deleted products and products with nil or future available_on date are not available


146

# File 'app/models/spree/product.rb', line 146

def available?
  !(available_on.nil? || available_on.future?) && !deleted?
end

#categorise_variants_from_option(opt_type) ⇒ Object

split variants list into hash which shows mapping of opt value onto matching variants eg categorise_variants_from_option(color) => -> […], “blue” -> […]


152
153
154
155
# File 'app/models/spree/product.rb', line 152

  return {} unless option_types.include?(opt_type)
  variants.active.group_by { |v| v.option_values.detect { |o| o.option_type == opt_type} }
end

#deleted?Boolean

use deleted? rather than checking the attribute directly. this allows extensions to override deleted? if they want to provide their own definition.


139
140
141
# File 'app/models/spree/product.rb', line 139

def deleted?
  !!deleted_at
end

#duplicateObject

for adding products which are closely related to existing ones define “duplicate_extra” for site-specific actions, eg for additional fields


131
132
133
134
# File 'app/models/spree/product.rb', line 131

def duplicate
  duplicator = ProductDuplicator.new(self)
  duplicator.duplicate

  options.empty? || options.any? do |opt|
    opt.option_type.option_values.empty?
  end
end

#ensure_option_types_exist_for_values_hashObject

Ensures option_types and product_option_types exist for keys in option_values_hash

    product_option_types.create(option_type_id: id) unless product_option_types.pluck(:option_type_id).include?(id)
  end
end

#has_variants?Boolean

the master variant is not a member of the variants array


102
103
104
# File 'app/models/spree/product.rb', line 102

def has_variants?
  variants.any?
end

#masterObject

Master variant may be deleted (i.e. when the product is deleted) which would make AR's default finder return nil. This is a stopgap for that little problem.

#variants_and_option_values(current_currency = nil) ⇒ Object

Suitable for displaying only variants that has at least one option value. There may be scenarios where an option type is removed and along with it all option values. At that point all variants associated with only those values should not be displayed to frontend users. Otherwise it breaks the idea of having variants
