ruby on rails 3 - Can't mass-assign protected attributes for Nested simple_form -


i have form nests store fields within seller fields. this

= simple_form_for @seller, url: pages_path |f|   .span3     h5.capital personal/contact details     = f.input :name, label: false, placeholder: 'full name (owner/manager)'     = f.input :mobile, label: false, placeholder: 'mobile phone no.'     = f.input :landline, label: false, placeholder: 'landline no. (with std code)'     = f.input :email, label: false, placeholder: 'email id'   .span5     h5.capital store details     = f.simple_fields_for :store_attributes |builder|       = builder.input :name, label: false, placeholder: 'store name'       = builder.input :address, label: false, placeholder: 'full address'       = builder.input :city, label: false, placeholder: 'city/district',        = builder.input :pincode, label: false, placeholder: 'pincode', class: 'pincode'       = builder.input :website, label: false, placeholder: 'website/facebook page'

and seller model looks this

class seller < user attr_accessible :landline, :mobile, :name, :store_attributes  has_one :store  accepts_nested_attributes_for :store  validates :name, presence: true validates :mobile, presence: true validates :landline, presence: true end

here controller code

def create @seller = seller.new(params[:seller]) @store = store.new(params[:store])  if @seller.save & @store.save   redirect_to @seller else   render 'home' end end

and when submit form , following error

activerecord::unknownattributeerror in pagescontroller#create unknown attribute: seller_id

please guide me on how has resolved while keeping whitelist_attributes = true.

many thx.
