Can you post your create and update methods as you now have them so I
can see what you are doing.
Sure, here goes :
def create
@lead = Lead.new( params[:lead] )
@lead.illustration = upload_image
if @lead.save
flash[:success] = "Leaderboard successfully added."
redirect_to @lead
else
redirect_to root_path
end
end
def update
@lead = Lead.find_by_id( params[:id] )
params[:lead][:illustration] = upload_image
if @lead.update_attributes( params[:lead] )
flash[:success] = "Leaderboard successfully updated."
redirect_to @lead
else
render action: "edit"
end
end
def upload_image
if params[:lead][:illustration]
uploaded_io = params[:lead][:illustration]
File.open(Rails.root.join('app', 'assets', 'images', uploaded_io.original_filename), 'wb') do |file|
file.write(uploaded_io.read)
end
return "#{uploaded_io.original_filename}"
end
end
