error_messages_for

in your form view:

error_messages_for :resource

or

error_messages_for @resource

name url

example: in your DM model add a name_url property

property :name_url, String, length: 255

before :create do
  self.name_url = generate_url_from_name name
end

before create, the name_url will be generated to make your urls seo-friendly

Sinatra

helpers examples:

link_to "Label", "/your/link"

image_tag "/image/file.png"

include_js "antani" #=> <script src='/js/antani.js' ...>
include_css "antani" #=> <link href='/css/antani.css' ...>


%body{ class: body_class } #=> "/" -> home, "/posts/1" -> "posts", etc.

Paginable

Usage:

in your model add:

require 'voidtools/dm/paginable'
include Voidtools::Paginable

in a controller (or similar):

Model.paginate(page: params[:page])

in your view:

.pagination
  pag:
  - Model.pages.times do |i|
    %a{ :href => "/path?page=#{i}" }= i+1

(optional) in your model:

def self.per_page
 20
end

a simple stylesheet (sass):

.pagination
  margin: 10px 20px
  a
    padding: 3px 6px
    background: #DDD
  a:hover
    background: #FFF
