<% form_for @story do |f| %>
<%= f.text_field %>
<% end %>
there is no loop at all... why do we need to make it look like a loop?
Can't we do it without making it look like a loop? (write in another
way)?
Also, must be use a Story instance here? Can't we just use :story and
achieve the same result? The @story instance is just newly created and
has no data at all -- does it actually help creating the form? Can't
:story suffice already? thanks.
Both these examples of code use blocks, the first just happens to be a
loop, the second only looks like a loop if your first experience of
blocks is in loops.
I think it's important that you forget about the loop and focus on
blocks, once you've understood blocks, it will no longer look like a
loop and you'll understand that you really don't want to write it a
different way (even though it's possible)
Yes, you can use @story or :story and form_for will figure it out for you.
Mostly it depends on where you're using the form, new or edit etc.

can i use something like: (just pseudo code)
with (@story) do |f|
f.begin_form
f.textfield :name
f.end_form
end
so i think the block method will save the begin_form and end_form
because it automatically add the begin and end before calling the block.
is that the main benefit?
