Can someone explain what is the correct way with Rails 1.2 to use a form to create an object. I know start_form_tag is changed to form_tag but what about form_for? I am trying to map a field on to field in the object which is created by a method call, so something like this def password=(pass) and so on. However, this seems to work fine for me in some cases but not in others.

Both take blocks now. When using form_for, supply the block with a
symbol denoting the corresponding object, then you don''t have to
restate it everyplace:
<% form_for :people do |f| %>
<p>
name
<%= f.text_field :name %>
</p>
<p>
address
<%= f.text_field :address %>
</p>
<% end %>
In particular, this is great when there are multiple forms on the
same page. You specify:
<% form_for :people %>
# stuff here
<% end %>
<% form_for :addresses %>
#stuff here
<% end %>
Does this help?

Ok, I have rewritten my form code to follow this but its not solving my core
problem.
Maybe its just me but rails seems a bit of a mess when it comes to form
code.
I have one app that runs against 1.1.6. I have a form with the following
code:
<%= form.file_field("jar_file") %>
In my model I have:
def jar_file=(jar_field)
#stuff
end
This works fine. Howevern in a new app running on rails 1.2.1 I have the
following code:
<%= f.password_field("password") %></p>
with this in my model:
def password=(pass)
#stuff
end
This fails with the error:
undefined method `password'' for #<User:0x377e560>
Is there a ''correct'' approach for this. Rails seems to allow
me to set
up forms in
a number of ways but I can find nothing that says this is the right
way to do it.
