Release 0.12.0 (2019-12-05)


  • Django 2.1, 2.2 and 3.0 are now officially supported. Thanks to @atodorov for 3.0 compatibility
  • Added Python 3.7 and 3.8 support
  • Dropped Python 3.3 support


  • To ensure compatibility with JSON-RPC 1.2, 2 more “Content-Type” values are supported by JSON-RPC Handler: “application/json-rpc” and “application/jsonrequest” (#24). Thanks to @dansan

Release 0.11.1 (2018-05-13)


Last release introduced some undocumented breaking API changes regarding RPC registry management. Old API has been restored for backward compatibility. The following global functions are now back in the API:

  • modernrpc.core.register_rpc_method()
  • modernrpc.core.get_all_method_names()
  • modernrpc.core.get_all_methods()
  • modernrpc.core.get_method()
  • modernrpc.core.reset_registry()

In addition, some improvements have been applied to unit tests, to make sure test environment is the same after each test function. In addition, some exclusion patterns have been added in .coveragerc file to increase coverage report accuracy.

Release 0.11.0 (2018-04-25)


  • Django 2.0 is now officially supported. Tox and Travis default config have been updated to integrate Django 2.0 in existing tests environements.
  • Method’s documentation is generated only if needed and uses Django’s @cached_property decorator
  • HTML documentation default template has been updated: Bootstrap 4.1.0 stable is now used, and the rendering has been improved.

API Changes

  • Class RPCRequest has been removed and replaced by method execute_procedure(name, args, kwargs) in RPCHandler class. This method contains common logic used to retrieve a RPC method, execute authentication predicates to make sure it can be run, execute the concrete method and return the result.
  • HTML documentation content is not anymore marked as “safe” using django.utils.safestring.mark_safe(). You have to use Django decorator safe in your template if you display this value.


  • The kwargs dict passed to RPC methods can have customized keys (#18). Set the following values:

to override dict keys and prevent conflicts with your own methods arguments.

Other updates

  • Many units tests have been improved. Some tests with many calls to LiveServer have been splitted into shorter ones.

Release 0.10.0 (2017-12-06)


  • Logging system / error management
    • In case of error, current exception stacktrace is now passed to logger by default. This allows special handler like django.utils.log.AdminEmailHandler or raven.handlers.logging.SentryHandler to use it to report more useful information (#13)
    • Error messages have been rewritten to be consistent across all modules and classes
    • Decrease log verbosity: some INFO log messages now have DEBUG level (startup methods registration)
  • Documentation has been updated
    • Added a page to explain how to configure RPC methods documentation generation, and add a note to explicitly state that markdown or docutils package must be installed if settings.MODERNRPC_DOC_FORMAT is set to non-empty value (#16)
    • Added a page to list implemented system introspection methods
    • Added a bibliography page, to list all references used to write the library
  • Default template for generated RPC methods documentation now uses Bootstrap 4.0.0-beta.2 (previously 4.0.0-alpha.5)

Release 0.9.0 (2017-10-03)

This is a major release with many improvements, protocol support and bug fixes. This version introduce an API break, please read carefully.


  • Class RPCException and its subclasses now accept an additional data argument (#10). This is used by JSON-RPC handler to report additional information to user in case of error. This data is ignored by XML-RPC handler.
  • JSON-RPC: Batch requests are now supported (#11)
  • JSON-RPC: Named parameters are now supported (#12)
  • JSON-RPC: Notification calls are now supported. Missing id in payload is no longer considered as invalid, but is correectly handled. No HTTP response is returned in such case, according to the standard.
  • XML-RPC: exception raised when serializing data to XML are now catched as InternalError and a clear error message

API Changes

  • modernrpc.handlers.JSONRPC and modernrpc.handlers.XMLRPC constants have been moved and renamed. They become respectively modernrpc.core.JSONRPC_PROTOCOL and modernrpc.core.XMLRPC_PROTOCOL
  • RPCHandler class updated, as well as subclases XMLRPCHandler and JSONRPCHandler. RPCHandler.parse_request() is now RPCHandler.process_request(). The new method does not return a tuple (method_name, params) anymore. Instead, it executes the underlying RPC method using new class RPCRequest. If you customized your handlers, please make sure you updated your code (if needed).

Minor updates

  • Code has been improved to prepare future compatibility with Django 2.0

Release 0.8.1 (2017-10-02)


This version is a security fix. Upgrade is highly recommended

Security fix

  • Authentication backend is correctly checked when executing method using system.multicall()

Release 0.8.0 (2017-07-12)


  • Fixed invalid HTML tag rendered from RPC Method documentation. Single new lines are converted to space since they are mostly used to limit docstrings line width. See pull request #7, thanks to @adamdonahue
  • Signature of auth.set_authentication_predicate has been fixed so it can be used as decorator (#8). Thanks to @aplicacionamedida

Release 0.7.1 (2017-06-24)

Minor fix

  • Removed useless settings variable introduced in last 0.7.0 release. Logging capabilities are now enabled by simply configuring a logger for modernrpc.* modules, using Django variable LOGGING. The documentation has been updated accordingly.

Release 0.7.0 (2017-06-24)


  • Default logging behavior has changed. The library will not output any log anymore, unless MODERNRPC_ENABLE_LOGGING is set to True. See documentation for more information

Release 0.6.0 (2017-05-13)

Performance Improvements

  • Django cache system was previously used to store the list of available methods in the current project. This was useless, and caused issues with some cache systems (#5). Use of cache system has been removed. The list of RPC methods is computed when the application is started and kept in memory until it is stopped.

Release 0.5.2 (2017-04-18)


  • HTTP Basic Authentication backend: User instance is now correctly stored in current request after successful authentication (#4)
  • Unit testing with Django 1.11 is now performed against release version (Beta and RC are not tested anymore)
  • Various Documentation improvements

Release 0.5.1 (2017-03-25)


  • When RPC methods are registered, if a module file contains errors, a python warning is produced. This ensure the message will be displayed even if the logging system is not configured in a project (#2)
  • Python 2 strings standardization. Allow to configure an automatic conversion of incoming strings, to ensure they have the same type in RPC method, no matter what protocol was used to call it. Previously, due to different behavior between JSON and XML deserializers, strings were received as str when method was called via XML-RPC and as unicode with JSON-RPC. This standardization process is disabled by default, and can be configured for the whole project or for specific RPC methods.
  • Tests are performed against Django 1.11rc1
  • modernrpc.core.register_method() function was deprecated since version 0.4.0 and has been removed.

Release 0.5.0 (2017-02-18)


  • Typo fixes
  • JSON-RPC 2.0 standard explicitly allows requests without ‘params’ member. This doesn’t produce error anymore.
  • Setting variable MODERNRPC_XML_USE_BUILTIN_TYPES is now deprecated in favor of MODERNRPC_XMLRPC_USE_BUILTIN_TYPES
  • Unit tests are now performed with python 3.6 and Django 1.11 alpha, in addition to supported environment already tested. This is a first step to full support for these environments.
  • HTTP “Basic Auth” support: it is now possible to define RPC methods available only to specific users. The control can be done on various user attributes: group, permission, superuser status, etc. Authentication backend can be extended to support any method based on incoming request.

Release 0.4.2 (2016-11-20)


  • Various performance improvements
  • Better use of logging system (python builtin) to report errors & exceptions from library and RPC methods
  • Rewritten docstring parser. Markdown and reStructured formatters are still supported to generate HTML documentation for RPC methods. They now have unit tests to validate their behavior.
  • @rpc_method decorator can be used with or without parenthesis (and this feature is tested)
  • System methods have been documented

Release 0.4.1 (2016-11-17)


  • Method arguments documentation keep the same order as defined in docstring
  • A simple warning is displayed when MODERNRPC_METHODS_MODULES is not set, instead of a radical ImproperlyConfigured exception.
  • Some traces have been added to allow debugging in the module easily. It uses the builtin logging framework.

Release 0.4.0 (2016-11-17)

API Changes

  • New unified way to register methods. Documentation in progress
  • XMl-RPC handler will now correctly serialize and unserialize None values by default. This behavior can be configured using MODERNRPC_XMLRPC_ALLOW_NONE setting.


  • When django use a persistent cache (Redis, memcached, etc.), ensure the registry is up-to-date with current sources at startup

Release 0.3.2 (2016-10-26)


  • Include missing templates in pypi distribution packages

Release 0.3.1 (2016-10-26)


  • HTML documentation automatically generated for an entry point
  • system.multicall is now supported, only in XML-RPC
  • Many tests added

Release 0.3.0 (2016-10-18)

API Changes


  • RPC methods can now declare the special **kwargs parameter. The dict will contain information about current context (request, entry point, protocol, etc.)
  • About 12 tests added to increase coverage
  • Many documentation improvements
  • system.methodHelp is now supported

Release 0.2.3 (2016-10-13)

Minor change

  • Useless tests & testsite packages have been removed from Pypi distributions (binary & source)

Release 0.2.2 (2016-10-13)

Minor change

  • Useless tests packages have been removed from Pypi distributions (binary & source)

Release 0.2.1 (2016-10-12)


Release 0.2.0 (2016-10-05)


  • Added very basic documentation:
  • system.listMethods is now supported
  • system.methodSignature is now supported
  • Error reporting has been improved. Correct error codes and messages are returned on usual fail cause. See module modernrpc.exceptions for more information.
  • Many unit tests have been added to increase test coverage of the library

Release 0.1.0 (2016-10-02)
