Reason: This is slower, and any? is not equivalent in the
general case.

add namespace options to form_for

Used any? instead of length call

New records should load has_many relationships with custom primary keys

You can provide a namespace for your form to ensure uniqueness of id attributes on form elements.
The namespace attribute will be prefixed with underscore on the generate HTML id

Use any instead of length

Call a block passed rake_tasks method in the self context

avoid url started with "/" for the rails.png in public/index.html

fix label with block in erb

Object#in? also accepts multiple parameters

added tests to #3763

allow using orm_instance without invoking orm_class in generators

Reference commits :

A recent change to beginning_of_week and end_of_week added an argument
that can be used to specify the week's starting day as a symbol. Now
these methods were aliased as monday and sunday respectively which as a
consequence of the argument addition, made calls like obj.monday(:sunday)
possible. This commit makes them methods on their own.

Warning removed unused variable

mentioned about OS X and windows usually having a JS runtime

Rationale: this is more readable if serveral queries
are involved in one call. Also, it will be possible
to let AR log EXPLAINs automatically in production
mode, where queries are not even around.

beginning_of_week extended in both Time and Date so that to return week start based on start day that is monday by default
