Adds the ability to save custom types, which type cast to non-primitive
ruby objects.

Need to check if valud also respond_to :id before calling it, otherwise
things could explode.

This reverts commit 408227d9, reversing
changes made to dca0b57d.

because of an ambiguous column name. This happened if the association
model had a default scope that referenced a third table, and the third
table also referenced the original table (with an identical
foreign_key).

Mysql requires that ambiguous columns are deambiguated by using the full
table.column syntax. Postgresql and Sqlite use a different syntax for
updates altogether (and don't tolerate table.name syntax), so the fix
requires always including the full table.column and discarding it later
for Sqlite and Postgresql.

This patch fixes quoting for ActiveSupport::Duration instances:

    # before
    >> ActiveRecord::Base.connection.quote 30.minutes
    => "'--- 1800\n...\n'"

    # after
    >> ActiveRecord::Base.connection.quote 30.minutes
    => "1800"

Also, adds a test for type casting ActiveSupport::Duration instances.

Related to #1119.

quoted_date converts time-like objects to ActiveRecord::Base.default_timezone before serialization. This allows you to use Time.now in find conditions and have it correctly be serialized as the current time in UTC when default_timezone == :utc [#2946 state:resolved]

be like a duck. Let's not rely on explicit classes, so we can pass proxy objects around and have them interpreted correctly by ActiveRecord's serialization routines

 Numeric and decimal columns map to BigDecimal instead of Float. Those with scale 0 map to Integer. Closes #5454.

Add option (true by default) to generate reader methods for each attribute of a record to avoid the overhead of calling method missing. In partial fullfilment of #1236.

* SQLite schema has been updated
* Postgresql schema needs to be fixed too
Simplify AR::Base#toggle to store the boolean, not the quoted value
* expand the tests
