"declarative". Pass in the decorated property using
the "instrument" keyword argument, e.g.:
somekey = synonym('_somekey', instrument=property(g, s))
- declared_synonym deprecated
which allows Table and mapper() configuration to take place
inline underneath a class declaration. This extension differs
from ActiveMapper and Elixir in that it does not redefine
any SQLAlchemy semantics at all; literal Column, Table
and relation() constructs are used to define the class
behavior and table definition.
- added 2.4-style binops to util.Set on 2.3
- OrderedSets pickle on 2.3
- more lib/sqlalchemy set vs Set corrections
- fixed InstrumentedSet.discard for 2.3
- set, sorted compatibility for test suite
- added testing.fails_if decorator
- Importing testenv has no side effects- explicit functions provide similar behavior to the old immediate behavior of testbase
- testing.db has the configured db
- Fixed up the perf/* scripts
- Collections gain a @converter framework for flexible validation and adaptation of bulk assignment
- Bogus bulk assignments now raise TypeError instead of exceptions.ArgumentError
e.g. if you pickle a series of objects and unpickle (i.e. as in a Pylons HTTP session
or similar), they can go into a new session without any conflict
- added stricter checks around session.delete() similar to update()
- shored up some old "validate" stuff in session/uow
Fix to null FLOAT fields in mssql-trusted.patch
MSSQL: LIMIT with OFFSET now raises an error
MSSQL: can now specify Windows authorization
MSSQL: ignores seconds on DATE columns (DATE fix, part 1)
into a new set of methods available off of Query. These methods
all provide "generative" behavior, whereby the Query is copied
and a new one returned with additional criterion added.
The new methods include:
filter() - applies select criterion to the query
filter_by() - applies "by"-style criterion to the query
avg() - return the avg() function on the given column
join() - join to a property (or across a list of properties)
outerjoin() - like join() but uses LEFT OUTER JOIN
limit()/offset() - apply LIMIT/OFFSET
range-based access which applies limit/offset:
session.query(Foo)[3:5]
distinct() - apply DISTINCT
list() - evaluate the criterion and return results
no incompatible changes have been made to Query's API and no methods
have been deprecated. Existing methods like select(), select_by(),
get(), get_by() all execute the query at once and return results
like they always did. join_to()/join_via() are still there although
the generative join()/outerjoin() methods are easier to use.
- the return value for multiple mappers used with instances() now returns
a cartesian product of the requested list of mappers, represented
as a list of tuples. this corresponds to the documented behavior.
So that instances match up properly, the "uniquing" is disabled when
this feature is used.
- strings and columns can also be sent to the *args of instances() where
those exact result columns will be part of the result tuples.
- query() method is added by assignmapper. this helps with
navigating to all the new generative methods on Query.
- documented instance variables in ANSICompiler
- fixed [ticket:120], adds "inline_params" set to ANSICompiler which DefaultDialect picks up on when
determining defaults. added unittests to query.py
- additionally fixed up the behavior of the "values" parameter on _Insert/_Update
- more cleanup to sql/Select - more succinct organization of FROM clauses, removed silly _process_from_dict
methods and JoinMarker object
