Question

i\'m new to ruby on rails and am working with version 2.3 on mac osx. i am trying to create the same functionality a scaffold creates, but on my own. i created a \"post\" co

Answer 1

if you use symbol :post it creates

if you use the instance @post

for @post = Post.new you will get

for @post = Post.find(1) you will get

if you have different forms for your new and your edit no big deal but more likey than not your new and your edit forms are going to be identical or close to it

so if you use the instance variable @post you can put all the form code into _form and just call the partial and it will handle the rest based on if you pass in a new record or an existing record
