<p>Released 12 Feb 2007.</p>
<div class="section" id="features-interface">
<h2>Features & Interface</h2>
<ul>
<li><p class="first">It is now possible to create tables that reference each other.
Constraints (in the DBMSes that support constraints) are added after the
tables have been created.</p>
</li>
<li><p class="first">Added <tt class="docutils literal">createSQL</tt> as an option for sqlmeta. Here you can add
related SQL you want executed by sqlobject-admin create after table
creation. createSQL expects a string, list, or dictionary. If using
a dictionary the key should be a dbName value (ex. 'postgres') and
the value should be a string or list. Examples in
sqlobject/tests/test_sqlobject_admin.py or at
<<a href="http://sqlobject.org/sqlobject-admin.html#the-create-command" class="reference external">http://sqlobject.org/sqlobject-admin.html#the-create-command</a>></p>
</li>
<li><p class="first">Added method <tt class="docutils literal">sqlhub.doInTransaction(callable, *args, **kwargs)</tt>,
to be used like:</p>
<pre class="literal-block">
sqlhub.doInTransaction(process_request, os.environ)
</pre>
<p>This will run <tt class="docutils literal">process_request(os.environ)</tt>. The return
value will be preserved.</p>
</li>
<li><p class="first">Added method <tt class="docutils literal"><span class="pre">.getOne([default])</span></tt> to <tt class="docutils literal">SelectResults</tt> (these are
the objects returned by <tt class="docutils literal">.select()</tt> and <tt class="docutils literal">.selectBy()</tt>). This
returns a single object, when the query is expected to return only
one object. The single argument is the value to return when zero
results are found (more than one result is always an error). If no
default is given, it is an error if no such object exists.</p>
</li>
<li><p class="first">Added a WSGI middleware (in <tt class="docutils literal">sqlobject.wsgi_middleware</tt>) for
configuring the database for the request. Also handles
transactions. Available as <tt class="docutils literal">egg:SQLObject</tt> in Paste Deploy
configuration files.</p>
</li>
<li><p class="first">New joins! ManyToMany and OneToMany; not fully documented yet, but still
more sensible and smarter.</p>
</li>
<li><p class="first">SELECT FOR UPDATE</p>
</li>
<li><p class="first">New module dberrors.py - a hierarchy of exceptions. Translation of DB API
module's exceptions to the new hierarchy is performed for SQLite and MySQL.</p>
</li>
<li><p class="first">SQLiteConnection got a new keyword "factory" - a name or a reference to
a factory function that returns a connection class; useful for
implementing functions or aggregates. See test_select.py and
test_sqlite_factory.py for examples.</p>
</li>
<li><p class="first">SQLObject now disallows columns with names that collide with existing
variables and methods, such as "_init", "expire", "set" and so on.</p>
</li>
</ul>
</div>
<div class="section" id="small-features">
<h2>Small Features</h2>
<ul class="simple">
<li>Configurable client character set (encoding) for MySQL.</li>
<li>Added a close option to .commit(), so you can close the transaction as
you commit it.</li>
<li>DecimalValidator.</li>
<li>Added .expireAll() methods to sqlmeta and connection objects, to expire
all instances in those cases.</li>
<li>String IDs.</li>
<li>FOREIGN KEY for MySQL.</li>
<li>Support for sqlite3 (a builtin module in Python 2.5).</li>
<li>SelectResults cannot be queried for truth value; in any case it was
meaningless - the result was always True; now __nonzero__() raises
NotImplementedError in case one tries bool(MyTable.select()) or
"if MyTable.select():..."</li>
<li>With empty parameters AND() and OR() returns None.</li>
<li>Allows to use set/frozenset sets/Set/ImmutableSet sets as sequences
passed to the IN operator.</li>
<li>ID columns are now INT UNSIGNED for MySQL.</li>
</ul>
</div>
<div class="section" id="id5">
<h2>Bug Fixes</h2>

weak references.</li>
<li>Another round of bugfixes for MySQL errors 2006 and 2013 (SERVER_GONE,
SERVER_LOST).</li>

<h1>SQLObject 0.7.10</h1>

<h2>Bug Fixes</h2>
<ul class="simple">

<li>Fixed a bug with default field values for columns for Firebird connection.</li>
<li>Fixed a bug in col.createSQL().</li>

<li>Subqueries/subselects (<a href="http://sqlobject.org/docs/SQLObject.html#subqueries-subselects" class="reference external">see docs</a>).</li>
<li>Select results support <tt class="docutils literal">.filter(extra_query)</tt></li>
<li><tt class="docutils literal">SQLMultipleJoin</tt> and <tt class="docutils literal">SQLRelatedJoin</tt>, like <tt class="docutils literal">MultipleJoin</tt>
and <tt class="docutils literal">RelatedJoin</tt>, except return select results (@@: Document).</li>
<li><a href="http://sqlobject.org/docs/SQLObject.html#singlejoin-one-to-one" class="reference external">SingleJoin</a>.</li>
<li>Columns retain their order from the class definition to table
creation.</li>
<li>SQLObject now depends on the <a href="http://formencode.org" class="reference external">FormEncode</a>
library, and internal conversion/validation is done through
FormEncode (was previously using old fork of FormEncode).</li>
<li>Column instances can have attributes set on them (generally for
annotating columns with extra data).</li>
</ul>

<div class="section" id="id21">
<h2>Other Changes</h2>
<ul class="simple">
<li>When iterating over select results, a list is now immediately
created with the full list of instances being selected. Before
instances were created on demand, as select results were
pulled out row-by-row. The previous lazy behavior is available with
the method <tt class="docutils literal">lazyIter</tt>, used like <tt class="docutils literal">for obj in
<span class="pre">MyClass.select().lazyIter():</span> ...</tt>.</li>
<li>Test framework now uses <a href="http://codespeak.net/py/current/doc/test.html" class="reference external">py.test</a>.</li>
<li>SQLObject now uses a simpler metaclass
(<tt class="docutils literal">sqlobject.declarative.DeclarativeMeta</tt>).</li>
<li>autoCommit and queryIns ?? (@@: expand)</li>
<li>Deprecation (@@: document)</li>
<li>Use <a href="http://peak.telecommunity.com/DevCenter/setuptools" class="reference external">setuptools</a> for packaging
and installation.</li>
</ul>
</div>
<div class="section" id="id22">
<h2>Small Features</h2>
<ul class="simple">
<li><tt class="docutils literal">IntValidator</tt> for testing <tt class="docutils literal">IntCol</tt> inputs.</li>
<li>Base style (<tt class="docutils literal">sqlobject.styles.Style</tt>) is now a usable no-op style.</li>
<li>SQLite in-memory databases allowed with <tt class="docutils literal"><span class="pre">sqlite:/:memory:</span></tt></li>
<li>Keyword parameters allowed to <tt class="docutils literal">connectionForURI</tt> (like
<tt class="docutils literal">debug=True</tt>).</li>
<li>More parameters passed to MySQL connections (unix_socket,
named_pipe, init_command, read_default_file, read_default_group,
connect_time, compress, named_pipe, use_unicode, client_flag,
local_infile).</li>
<li><tt class="docutils literal">DateTimeCol.now</tt> is a function for producing the current date,
using whatever date/time module you are using (good for use as a
default).</li>
<li>Inherited classes fetched more efficiently (fewer queries).</li>
<li>Decimal converter to create <a href="http://python.org/doc/current/lib/module-decimal.html" class="reference external">decimal objects</a>.</li>
<li>Repository rearranged (now in
<tt class="docutils literal"><span class="pre">http://svn.colorstudy.com/SQLObject/trunk</span></tt>).</li>
</ul>
</div>
<div class="section" id="id23">
<h2>Bug Fixes</h2>
<ul class="simple">
<li>Tables with no columns can work. Why would you have a table without
a column? We do not know, we try only to serve.</li>
<li>Sybase <tt class="docutils literal">_fromDatabase</tt> fixed.</li>
<li>Various fixes to support most recent <tt class="docutils literal">MySQLdb</tt> adapter, and
<tt class="docutils literal">pysqlite</tt> adapters.</li>
<li>URI parsing improved, including Windows paths (for use with SQLite).</li>
<li><tt class="docutils literal">selectBy(column=None)</tt> creates <tt class="docutils literal">IS NULL</tt> query.</li>
<li><tt class="docutils literal">selectBy(foreignKey=value)</tt> now supported (not just selecting by
foreign key ID).</li>
<li><tt class="docutils literal"><span class="pre">cascade='null'</span></tt> wasn't working properly (was cascading all
deletes, not nullifying!).</li>
<li>Lots of other bug fixes.</li>
