# === Removing hidden model id's
#
# The form_for method automatically includes the model id as a hidden field in the form.
# This is used to maintain the correlation between the form data and it's associated model.
# Some ORM systems do not use id's on nested models so in this case you want to be able
# to disable the hidden id.
#
# In the following example the Post model has many Comments stored within it in a NoSQL database,
# thus there is no primary key for comments.
#
# Example:
#
# <%= form(@post) do |f| %>
# <% f.fields_for(:comments, :include_id => false) do |cf| %>
# ...
# <% end %>
# <% end %>
#
# === Customized form builders
#
# You can also build forms using a customized FormBuilder class. Subclass
