MongoMapper - undefined method `keys'
- by nimnull
I'm trying to create a Document instance with params passed from the post-submitted form:
My Mongo mapped document looks like:
class Good
include MongoMapper::Document
key :title, String
key :cost, Float
key :description, String
timestamps!
many :attributes
validates_presence_of :title, :cost
end
And create action:
def create
@good = Good.new(params[:good])
if @good.save
redirect_to @good
else
render :new
end
end
params[:good] containes all valid document attributes - {"good"={"cost"="2.30", "title"="Test good", "description"="Test description"}}, but I've got a strange error from rails:
undefined method `keys' for ["title", "Test good"]:Array
My gem list:
