2014-01-25T21:20:46+00:00

- start building out very comprehensive docstrings for core functions

2014-01-25T20:36:09+00:00

- happy new year

2014-01-05T21:57:05+00:00

- conjunctions like and_() and or_() can now accept generators as arguments.

- adjust the behavior of cast() to only provide a type for the bindparam()

2013-12-28T21:37:54+00:00

if we are coercing straight from string.  [ticket:2899]
- rework the tests here to be individual

- rework the JSON expression system so that "astext" is called after

2013-12-27T23:25:57+00:00

the indexing.  this is for more natural operation.
- also add cast() to the JSON expression to complement astext. This integrates
the CAST call which will be needed frequently.  Part of [ticket:2687].
- it's a little unclear how more advanced unicode attribute-access is going to go,
some quick attempts at testing yielded strange error messages from psycopg2.
- do other cross linking as mentioned in [ticket:2687].

- The :func:`.cast` function, when given a plain literal value,

2013-12-17T20:38:35+00:00

will now apply the given type to the given literal value on the
bind parameter side according
to the type given to the cast.   This essentially replaces what would
normally be the detected type of the literal value.   This only
takes effect if the auto-detected type of the literal value is either
"nulltype" (e.g. couldn't detect)
or a type that is of the same "affinity" as the cast type.
The net change here is that the :func:`.cast` function includes more
of the functionality already present in the :func:`.type_coerce` function.
