Notes

Here is a sample usage of its,

==== Code example

describe '#rate_for_date' do
context 'with date with in the range' do
  subject do 
    FactoryGirl.build(:allocated_room_rate, 
        start_date: Time.zone.now, 
        end_date: 2.day.from_now, 
        price: 100...

select :object, :method, (1..5)

The example code will not work unless class inherits from ActionController::Metal (to get functioning controller) or at least AbstractController:Base.

You can use an array to build a URL instead of a URL helper (e.g. edit_admin_user_path(event.user), which would fail when an event has no user:

link_to_if event.user, event.user_name, [:edit, :admin, event.user]

Re: Gramatical error

=== We invited the strippers, JFK, and Stalin.

versus the appositive phrase:

=== We invited the strippers, JFK and Stalin.

(Really, you need to see the comic to appreciate the difference.)

Hi - not sure where I would submit this so just putting here. My apologies if not in the right place.

default: “, and ” - this is grammatically wrong. There should be no comma with the last and.

Example:

['one', 'two', 'three'].to_sentence

should give: "one, two and three"

There is no ' .......

====In the example

select("post", "person_id", Person.all.collect {|p| [ p.name, p.id ] }, { include_blank: true })

It can be updated to

select("post", "person_id", Person.pluck(:name, :id), { include_blank: true })

1.9.3p392 :013 > x = "picture.2.jpg" => "picture.2.jpg"

1.9.3p392 :015 > x.rpartition('.') => ["picture.2", ".", "jpg"]

As a note, you can use it like this:

after_save {|instance|

}

it will pass in the instance being saved.

Similar to danwich's note[http://apidock.com/rails/ActionView/Helpers/FormHelper/form_for#1226-form-for-with-as-routing)], if you specify a route using the :path option

resource :posts, path: 'articles'

then the form_for tag must specify the :url option

form_for(@post), url: post_path(@po...

So the way to do the equivalent of a has_many :through is to use has_one :through, with the expected names.

so using the other example we could do

=== eg class Person < ActiveRecord::Base belongs_to :team ... end class Task < ActiveRecord::Base belongs_to :person has_o...

If you provide the :callback option with a nil value, then the default JSON object will be returned. As such, this makes creating JSONP response from the render syntax very easy in your controllers, like so:

render json: @object, callback: params[:jsoncallback]

If you’d like to read someone’s RSS feed with your Ruby code, you’ve come to the right place

No, you've definitely come to wrong place. RSS is one of the worst documented libraries I've ever seen for Ruby. It's as confusing and misleading as it can get.

See http://apidock.com/rails/v4.0.2/ActiveRecord/QueryMethods/select

You can also pass string as an alternative to :symbol

k = Klass.new

k.send "hello", "gentle", "readers" #=> "Hello gentle readers"

options_from_collection_for_select(@posts, :slug, :title, params[:slug])

Consider using symbols for performance, otherwise it will generate a string each time instead of a symbol which will reference the same object.

Nope. Read it again:

This generates a sequence of self.size n-element arrays

If any of the arguments are longer than the receiver, the elements beyond the receiver's length are ignored

I tried to add a array value using hidden_field_tag and access it in jquery. It just returns the flattened version of array. eg:(If i try to store [1,[1,2,3]] in hidden_field_tag , in jquery iam just getting '1 1 2 3') but if i use input field with type=hidden iam getting the correct value. Why is...

order can be specified as a hash, e.g.:

order(id: :desc)

This will prevent "ambiguous column" errors when the order is used with joins or includes.
