@classmethod
def create_for_statement(cls, statement, compiler, **kw): (source)
overrides sqlalchemy.orm.context.AbstractORMCompileState.create_for_statement

Create a context for a statement given a :class:`.Compiler`. This method is always invoked in the context of SQLCompiler.process(). For a Select object, this would be invoked from SQLCompiler.visit_select(). For the special FromStatement object used by Query to indicate "Query.from_statement()", this is called by FromStatement._compiler_dispatch() that would be called by SQLCompiler.process().
