Unable to display validation errors using the gem 'bootstrap_forms', '~> 2.0.0' (http://github.com/potenza/bootstrap_form).
models/client.rb
class Client < ActiveRecord::Base
attr_accessible :name
validates :name, :presence => true
end
views/clients/new.html.haml
= bootstrap_form_for @client do |f|
= f.object.errors.messages
%h1 Create New Client
.row-fluid
.span3= f.text_field :name, :class => 'span50'
= f.submit
When submitting the above form code, f.object.class is 'Client', and f.object.messages is an empty hash.
Switching this code to use rails built in form builder allows me to see the validation errors:
views/clients/new.html.haml
= form_for @client do |f|
= f.object.errors.messages
%h1 Create New Client
.row-fluid
.span3= f.text_field :name, :class => 'span50'
= f.submit
Using this, f.object.messages is {:name=>["can't be blank"]}.
Does this make any sense? I cannot understand why f.object.errors.messages is empty.

Try this:
f.errors.full_messages
