c196ca72a0 Ensure StatementCache#execute never raises RangeError
Since 31ffbf8d, finder methods no longer raise `RangeError`. So
`StatementCache#execute` is the only place to raise the exception for
finder queries.

`StatementCache` is used for simple equality queries in the codebase.
This means that if `StatementCache#execute` raises `RangeError`, the
result could always be regarded as empty.
So `StatementCache#execute` just return nil in that range error case,
and treat that as empty in the caller side, then we can avoid catching
the exception in much places.

The current code base is not uniform. After some discussion,
we have chosen to go with double quotes by default.

0a12a5f816 Deprecate eager-evaluated scopes.
Don't use this:

    scope :red, where(color: 'red')
    default_scope where(color: 'red')

Use this:

    scope :red, -> { where(color: 'red') }
    default_scope { where(color: 'red') }

The former has numerous issues. It is a common newbie gotcha to do
the following:

    scope :recent, where(published_at: Time.now - 2.weeks)

Or a more subtle variant:

    scope :recent, -> { where(published_at: Time.now - 2.weeks) }
    scope :recent_red, recent.where(color: 'red')

Eager scopes are also very complex to implement within Active
Record, and there are still bugs. For example, the following does
not do what you expect:

    scope :remove_conditions, except(:where)
    where(...).remove_conditions # => still has conditions

6f84c73dc4 Un-deprecate using 'default_scope' as a macro, but if you are calling the macro multiple times that will give deprecation warnings, and in 3.2 we will simply overwrite the default scope when you call the macro multiple times. 2011-04-18 23:15:38 +01:00

05bcb8cecc Support the :dependent option on has_many :through associations. For historical and practical reasons, :delete_all is the default deletion strategy employed by association.delete(*records), despite the fact that the default strategy is :nullify for regular has_many. Also, this only works at all if the source reflection is a belongs_to. For other situations, you should directly modify the through association. 2011-02-07 23:35:05 +00:00
