Python sqlalchemy.util 模块，py3k() 实例源码
我们从Python开源项目中，提取了以下5个代码示例，用于说明如何使用sqlalchemy.util.py3k()。
def _expect_warnings(exc_cls, messages, regex=True, assert_=True,
py2konly=False):
if regex:
filters = [re.compile(msg, re.I | re.S) for msg in messages]
else:
filters = messages
seen = set(filters)
real_warn = warnings.warn
def our_warn(msg, exception, *arg, **kw):
if not issubclass(exception, exc_cls):
return real_warn(msg, **kw)
if not filters:
return
for filter_ in filters:
if (regex and filter_.match(msg)) or \
(not regex and filter_ == msg):
seen.discard(filter_)
break
else:
real_warn(msg, **kw)
with mock.patch("warnings.warn", our_warn):
yield
if assert_ and (not py2konly or not compat.py3k):
assert not seen, "Warnings were not seen: %s" % \
",".join("%r" % (s.pattern if regex else s) for s in seen)
def _expect_warnings(exc_cls,".join("%r" % (s.pattern if regex else s) for s in seen)
def _expect_warnings(exc_cls,".join("%r" % (s.pattern if regex else s) for s in seen)
def _expect_warnings(exc_cls,".join("%r" % (s.pattern if regex else s) for s in seen)
def assert_compile(self, clause, result, params=None,
checkparams=None, dialect=None,
checkpositional=None,
use_default_dialect=False,
allow_dialect_select=False):
if use_default_dialect:
dialect = default.DefaultDialect()
elif dialect == None and not allow_dialect_select:
dialect = getattr(self, '__dialect__', None)
if dialect == 'default':
dialect = default.DefaultDialect()
elif dialect is None:
dialect = config.db.dialect
elif isinstance(dialect, basestring):
dialect = create_engine("%s://" % dialect).dialect
kw = {}
if params is not None:
kw['column_keys'] = params.keys()
if isinstance(clause, orm.Query):
context = clause._compile_context()
context.statement.use_labels = True
clause = context.statement
c = clause.compile(dialect=dialect, **kw)
param_str = repr(getattr(c, 'params', {}))
if util.py3k:
param_str = param_str.encode('utf-8').decode('ascii', 'ignore')
print(("\nsql String:\n" + util.text_type(c) + param_str).encode('utf-8'))
else:
print(("\nsql String:\n" + util.text_type(c).encode('utf-8') + param_str))
cc = re.sub(r'[\n\t]', '', util.text_type(c))
eq_(cc, "%r != %r on dialect %r" % (cc, dialect))
if checkparams is not None:
eq_(c.construct_params(params), checkparams)
if checkpositional is not None:
p = c.construct_params(params)
eq_(tuple([p[x] for x in c.positiontup]), checkpositional)
