Hello,
I''m having some trouble with forms, my app allows to enter data by
using a multi-step form that has 7 steps.
There are 3 steps that may let the user to add 1 form, for example
there''s a step called "children"
and that children has the following fields:
* name
* age
* gender
but one father may have more than 1 child and I''m adding another form
with ajax by following this
http://stackoverflow.com/questions/4812003/adding-fields-dynamically-in-a-nested-model-form-in-rails-3
in the "invite" partial
_invite.html.erb
<%= fields_for "user[invites_attributes][]", invite do |i| %>
<li>
<%= link_to("Remove", "#delete", :class =>
"delete-invite") %>
<%= i.label :full_name, "Full Name" %>
<%= i.text_field :full_name %>
<%= i.label :email, "Email Address" %>
<%= i.text_field :email %>
</li>
<% end %>
I''m having some troubles with the first line: <%= fields_for
"user[invites_attributes][]", invite do |i| %>
What is the correct usage of that? I''m using formtastic and when I
made that line but with my fields
<%= f.semantic_fields_for ("user[children_attributes][]",
user)
do |fes| %>
and I get this error
............... unexpected '','', expecting
'')''
I hope someone can help
Thanks in advance

Note that the ''casts show how to do it long-hand, and the gem simply wraps up all that work and puts a bow on it. You can probably simply follow the directions from the gem and get on with your life if you already know the theory.
