In rails there is a nice way to make params required/permitted:

    before_filter :example_method

    def example_method
        params.required(:id).permit(:password)
    end

Order of bootstrap @imports care. For example it raises Undefine mixin ‘ie7-inline-block’

# app/assets/application.css.scss
/*
 *= require_self
 *= require_tree .
 */
 
@import "bootstrap/buttons";
@import "bootstrap/variables";
@import "bootstrap/mixins";

but this not

# app/assets/application.css.scss
/*
 *= require_self
 *= require_tree .
 */

@import "bootstrap/variables";
@import "bootstrap/mixins";
@import "bootstrap/buttons";

How to capture the block of code in rails helper? Here you have an example

# app/helpers/menus_helper.rb
module MenusHelper
  def link_to_menu(form, options = {}, &block)
    name = capture &block
    html = render :partial => 'example/partial', :locals => {:f => form}
    link_to_function name, html, options
  end
end

# index.html.haml
    = form @menu do |form|
        = link_to_menu form do
            %i.icon-menu
            Menu
        = form.submit

How to create routing like this in rails 3?

/accounts/numbers

First of all, create Accounts::NumbersController

$ rails generate controller accounts::numbers

User :path, :module and :as attributes for scope.

# config/routes.rb
...
scope :path => 'accounts', :module => 'accounts', :as => 'accounts' do
    resources :numbers, :only => [:create, :destroy]
end
...

And see your routing:

$ bundle exec rake routes
accounts_numbers POST   /accounts/numbers(.:format)           accounts/numbers#create
accounts_numbers DELETE /accounts/numbers/:id(.:format)       accounts/numbers#destroy

Rails namespace by default use :path, :module and :as

# config/routes.rb
...
namespace :accounts do
    resources :numbers, :only => [:create, :destroy]
end
...

I was surprised when I saw Postage for developers. Looks similar to stripe payments. I’m thinking about new startups “for developers” with exactly the same box which shows curl command and how easy it’s. Food for developers sounds good. Every team could be subscribe a food.

curl https://www.getfoodeasy.com/api/order \
  -u cueqNZUb3ldeWTNX7MU3Mel8UXtaAMUi: \
  -d 'company[name]=Apptamers' \
  -d 'address[street1]=388 Townsend St' \
  -d 'address[street2]=Apt 20' \
  -d 'address[zip]=94107' \
  -d 'order[position][]=Pizza'

Rails 4 has ActiveModel::Model. In rails 3 you can use combination of ActiveModel::Validations, ActiveModel::Conversion and ActiveModel::Naming

class TextMessage
  include ActiveModel::Validations
  include ActiveModel::Conversion
  extend ActiveModel::Naming

  attr_accessor :from, :to, :body

  validates :from, :presence => true
  validates :to, :presence => true
  validates :body, :presence => true

  def initialize(attributes = {})
    attributes.each do |name, value|
      send("#{name}=", value)
    end
  end

  def persisted?
    false
  end
end

When your page navigation has set fixed position like apptamers page, then you need to implement scroll to correct scroll down. Nice solution in jquery here:

$('a[href^="#"]').live('click',function(event){
    event.preventDefault();
    var offset = $(this.hash).offset() ? $(this.hash).offset().top : 0;
    var scrollTop = offset - 150;
    $('html, body').animate({ scrollTop: scrollTop }, 300);
});
