./databases/ruby-sequel, Model classes for the Sequel Database Toolkit

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 4.44.0, Package name: ruby22-sequel-4.44.0, Maintainer: pkgsrc-users

Sequel is a database access toolkit for Ruby. Sequel provides thread
safety, connection pooling, and a concise DSL for constructing queries
and table schemas.

Sequel makes it easy to deal with multiple records without having to
break your teeth on SQL.

This package contains model classes for Sequel that allow it to be used
as an object-relational mapping (ORM).

Update to 4.33.0

Upstream changes:

4.33.0.txt
doc/release_notes/4.33.0.txt
Last Update: 2016-04-01 07:24:12 -0700
New Features

    A Sequel::Model.require_valid_table accessor has been added. This setting is \ 
false for backwards compatibility, but if set to true, will raise an error you \ 
try to create a model class where an invalid table name is used or the schema or \ 
columns cannot be determined. This makes it easier to catch bugs, as things will \ 
fail fast, but it means that you must change code like:

    class Foo < Sequel::Model
      set_dataset :my_foos
    end

    to:

    class Foo < Sequel::Model(:my_foos)
    end

    as otherwise Foo will attempt to use the foos table by default when creating \ 
the class, which will raise an error as it is not the correct table name.

    Sequel::Database#transaction now supports a :savepoint=>:only option, \ 
which will create a savepoint if already inside a transaction, but will yield \ 
without creating a transaction if not inside a transaction. The use case for \ 
this is when you are running code that may raise an exception, and you don't \ 
want to invalidate the current transaction state.

Other Improvements

    The graph_each extension now splits results into subhashes when using \ 
Sequel::Dataset#first, as it did before Sequel 4.27.0.

    On PostgreSQL, Dataset#insert_conflict now accepts an array of columns as \ 
the value for the :target option.

    You can now pass a Sequel::SQL::Identifier or a \ 
Sequel::SQL::QualifiedIdentifer as the table argument when creating a foreign \ 
key. Previously, only symbols were supported, and using other values required \ 
specifying the :table option. So this will now work to reference a table that \ 
includes a double underscore:

    foreign_key :foo_id, Sequel.identifier(:fo__oo)

    Creating model classes inside a transaction on PostgreSQL where the implicit \ 
table name isn't correct no longer causes the transaction to fail.

    Similar issues were also fixed in the boolean_readers, boolean_subsets, and \ 
class_table_inheritance plugins.

    On PostgreSQL, You can now use the :qualify=>true option in the schema \ 
dumper, to dump using schema-qualified table names.

    On Microsoft SQL Server, the set_column_allow_null and set_column_not_null \ 
alter table methods now work on varchar(max), text, and similar columns.

    On Oracle, Sequel::Database#sequence_for_table now returns nil if given a \ 
table that doesn't exist or that the user does not have access to.

    Passing arbitrary objects to a model association method now indicates that \ 
the association should be reloaded, which was used to work but was broken in \ 
Sequel 4.32.0.

    It is now possible to raise Sequel::ValidationFailed and Sequel::HookFailed \ 
without an argument.

Backwards Compatibility

    Sequel::Model no longer swallows many errors when subclassing or setting \ 
datasets. While this should hopefully not affect backwards compatibility, it may \ 
break things where the methods were raising exceptions. If this does break \ 
backwards compatibility, it is most likely because it is no longer hiding \ 
another bug that should be fixed. Specific changes include:

        Model.inherited no longer rescues exceptions raised by set_dataset

        When subclassing a model that has a dataset, the columns and schema are \ 
just copied from the superclass

        Only Sequel::Error is rescued in calls to columns and schema, before it \ 
would rescue StandardError.

    The Sequel.firebird and Sequel.informix adapter methods have been removed, \ 
they are no longer needed as the firebird and informix adapters were removed a \ 
few versions back.
