sqlalchemy.ext.asyncio.result.AsyncMappingResult

class documentation

class AsyncMappingResult(AsyncCommon):

A wrapper for a _asyncio.AsyncResult that returns dictionary values rather than _engine.Row values.

The _asyncio.AsyncMappingResult object is acquired by calling the _asyncio.AsyncResult.mappings method.

Refer to the _result.MappingResult object in the synchronous SQLAlchemy API for a complete behavioral description.

New in version 1.4.

def __init__(self, result):

async def all(self):

Return all scalar values in a list.

Equivalent to _asyncio.AsyncResult.all except that mapping values, rather than _result.Row objects, are returned.

def columns(self, *col_expressions):

Establish the columns that should be returned in each row.

async def fetchall(self):

A synonym for the _asyncio.AsyncMappingResult.all method.

async def fetchmany(self, size=None):

Fetch many objects.

Equivalent to _asyncio.AsyncResult.fetchmany except that mapping values, rather than _result.Row objects, are returned.

async def fetchone(self):

Fetch one object.

Equivalent to _asyncio.AsyncResult.fetchone except that mapping values, rather than _result.Row objects, are returned.

async def first(self):

Fetch the first object or None if no object is present.

Equivalent to _asyncio.AsyncResult.first except that mapping values, rather than _result.Row objects, are returned.

def keys(self):

Return an iterable view which yields the string keys that would be represented by each .Row.

The view also can be tested for key containment using the Python in operator, which will test both for the string keys represented in the view, as well as for alternate keys such as column objects.

Changed in version 1.4: a key view object is returned rather than a plain list.

async def one(self):

Return exactly one object or raise an exception.

Equivalent to _asyncio.AsyncResult.one except that mapping values, rather than _result.Row objects, are returned.

async def one_or_none(self):

Return at most one object or raise an exception.

Equivalent to _asyncio.AsyncResult.one_or_none except that mapping values, rather than _result.Row objects, are returned.

async def partitions(self, size=None):

Iterate through sub-lists of elements of the size given.

Equivalent to _asyncio.AsyncResult.partitions except that mapping values, rather than _result.Row objects, are returned.

def unique(self, strategy=None):

Apply unique filtering to the objects returned by this _asyncio.AsyncMappingResult.

See _asyncio.AsyncResult.unique for usage details.
