ruby on rails - Cannot modify association 'SomeModels' because it goes through more than one other association -

i getting error when trying create/edit instance has few "has_many ... through" elements. have been looking workaround, have tried add together ", :autosave => false" on few , on relations nil seems work.

activerecord::hasmanythroughnestedassociationsarereadonly @ /customer/new cannot modify association 'customer#shops' because goes through more 1 other association.

this customer model 1 want create/edit:

class client < activerecord::base belongs_to :user has_many :customer_shop_groups has_many :shop_groups, -> { order(:name) }, through: :customer_shop_groups has_many :shops, -> { order(:name) }, through: :shop_groups has_one :api_consumer end

and these models have 'has_many...through' dependencies :

this customershopgroup model:

class customershopgroup < activerecord::base belongs_to :customer belongs_to :shop_group has_many :shops, through: :shop_group end

this shopgroup model:

class shopgroup < activerecord::base has_many :shops has_many :customer_shop_groups has_many :customers, through: :customer_shop_groups has_many :shop_group_maps, -> { order 'level' }, class_name: 'map' has_many :heatmaps, through: :shop_group_maps scope :with_friendly_id, lambda { |friendly_id| where(friendly_id: friendly_id) } end

and apiconsumer model:

class apiconsumer < activerecord::base belongs_to :customer has_many :shops, through: :customer end

it seems you're trying save shops in client form, not work. 1 way replacing has_many :shops, -> { order(:name) }, through: :shop_groups creating has_and_belongs_to_many association.
