(I'm still looking for some feedback on an equivalent way to do
accepts_nested_attributes for nested resources that are
ActiveModels.. instead of the hack I have below).
For the bad error message formatting...instead of stripping the
prefixes from the error messages I could use l18n
> <% @user.errors.full_messages.each do |msg| %>
> <%
> message = msg.gsub(/Credit card /, '').capitalize
> message = message.gsub(/Addresses /, '').capitalize
> %>
> <li><%= message %></li>
> <% end %>
after some trial and error I figured out how to to make l18n with
nested resources.
en:
activerecord:
attributes:
user:
credit_card:
agree: "Agreement"
card_verification: "Card Verification Value"
addresses:
address1: "Street Address"
I'll probably stick to using gsub for most cases (until I start
localizing all my text). Unless of course there is an automatic way
to make "Credit card card verification can't be blank" display "Card
verification can't be blank"
