How would I get the previous id from the database?
...would be
input and then rename an uploaded image to that row number.
So say the previous row was 19 and the image in that row was named
19.jpg, I''m wanting to name the next uploaded image as 20.jpg since the
row that would be added then would be 20.
Right now I''ve just got:
@new_tutorial = Tutorial.new(params[:tutorial])
File.open("#{RAILS_ROOT}/public/pictures/1.jpg", "wb") do |f|
f.write(@params[''image_url''].read)
end
Obviously the "1" in "1.jpg" needs to be dynamic.
