Filters in annotations crashed when used with numerical-type aggregations (i.e. Avg, StdDev, and Variance). This was caused as the source expressions no not necessarily have an output_field (such as the filter field), which lead to an AttributeError: 'WhereNode' object has no attribute output_field. Thanks to Chuan-Zheng Lee for the report. Regression in c690afb873cac8035a3cb3be7c597a5ff0e4b261 and two following commits.
The documentation in this tree is in plain text files and can be viewed using any text file viewer. It uses ReST (reStructuredText) [1], and the Sphinx documentation system [2]. This allows it to be built into other forms for easier viewing and browsing. To create an HTML version of the docs: * Install Sphinx (using ``python -m pip install Sphinx`` or some other method). * In this docs/ directory, type ``make html`` (or ``make.bat html`` on Windows) at a shell prompt. The documentation in _build/html/index.html can then be viewed in a web browser. [1] http://docutils.sourceforge.net/rst.html [2] http://sphinx-doc.org/
