im working with active admin i have collection_select or dropdown box
that populates the packages and crews im just wondering i why this
undefined method []' for nil:NilClass
i dont know what happened but it run few days ago and tested it once but
now it raises this error are there possible way to solve this?
def create
@package = Package.find(params[:package_crew][:package_id])
crew = Crew.find(params[:package_crew][:crew_id] )
@package_crew = @package.add_crew(crew.id)
if @package_crew.save
redirect_to {admin_package_crew_url}
end
end
thanks in advance more power to us all
i tried this
def create
#pid = params[:package_crew][:crew_id] if params[:package_crew]
pid,cid = 2 #tried nil,0…10
if params[:package_crew]
pid = params[:package_crew][:package_id]
cid = params[:package_crew][:crew_id]
end
@package = Package.find_by_id(pid)
crew = Crew.find_by_id(cid)
#@package = Package.find(params[:package_crew][:package_id])
#crew = Crew.find(params[:package_crew][:crew_id] )
@package_crew = @package.add_crew(crew.id)
if @package_crew.save
redirect_to {admin_package_crew_url}
end
end
add_crew method
def add_crew(crew_id)
current_package = package_crews.find_by_crew_id(crew_id)
if current_package
current_package.quantity = current_package.quantity.to_i + 1
else
current_package = package_crews.build(:crew_id => crew_id)
current_package.price = current_package.crew.price
end
current_package
end
