示例1: runOrderByTests
def runOrderByTests(self):
FeatureSourceTestCase.runOrderByTests(self)
# Combination with subset of attributes
request = QgsFeatureRequest().addOrderBy('num_char', False).setSubsetOfAttributes(['pk'], self.vl.fields())
values = [f['pk'] for f in self.vl.getFeatures(request)]
self.assertEqual(values, [5, 4, 3, 2, 1])
示例2: assert_query
def assert_query(self, source, expression, expected):
FeatureSourceTestCase.assert_query(self, source, expression, expected)
if self.compiled:
# Check compilation status
it = source.getFeatures(QgsFeatureRequest().setFilterExpression(expression))
if expression in self.uncompiledFilters():
self.assertEqual(it.compileStatus(), QgsAbstractFeatureIterator.NoCompilation)
elif expression in self.partiallyCompiledFilters():
self.assertEqual(it.compileStatus(), QgsAbstractFeatureIterator.PartiallyCompiled)
else:
self.assertEqual(it.compileStatus(), QgsAbstractFeatureIterator.Compiled)
示例3: runGetFeatureTests
def runGetFeatureTests(self, source):
FeatureSourceTestCase.runGetFeatureTests(self, source)
# combination of an uncompilable expression and limit
feature = next(self.vl.getFeatures('pk=4'))
context = QgsExpressionContext()
scope = QgsExpressionContextScope()
scope.setVariable('parent', feature)
context.appendScope(scope)
request = QgsFeatureRequest()
request.setExpressionContext(context)
request.setFilterExpression('"pk" = attribute(@parent, \'pk\')')
request.setLimit(1)
values = [f['pk'] for f in self.vl.getFeatures(request)]
self.assertEqual(values, [4])
