Instance Method Details

#available? ⇒ Boolean

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

Returns:

  • (Boolean)

# File 'app/models/spree/product.rb', line 160

determine if any variant (including master) can be supplied

Returns:

  • (Boolean)

174
175
 
# File 'app/models/spree/product.rb', line 173

def can_supply?
  variants_including_master.any?(&:can_supply?)
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” -> […]



179

181
182
 
# File 'app/models/spree/product.rb', line 179

  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.

Returns:

  • (Boolean)

168
169
170
 
# File 'app/models/spree/product.rb', line 168

def discontinued?

end

#duplicate ⇒ Object

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

# File 'app/models/spree/product.rb', line 119

def has_variants?
  variants.any?
end

#master ⇒ Object

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.

    Float::INFINITY

#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
