fix(provider)!: `RaygunMessage` object in `on_grouping_key` method #118

miquelbeltran · 2025-05-16T14:07:31Z

Description 📝

Purpose:

In the ticket #96 the customer reported that the object provided to the on_grouping_key callback was not a RaygunMessage object but rather a Dictionary.

This was caused by a bug in the filter_keys method as the customer pointed out.

Approach:

After some iterations, the filter_keys function has been changed so it does not accept RaygunMessage objects, and instead it can only be used with dictionaries (e.g. the RaygunMessage.details). This simplifies the implementation and avoids bugs like the one reported in #96 where the RaygunMessage was overridden.

This ensures that filter_keys doesn't break the class definition of RaygunMessage.

Then, the rest of the _post() method had to be fixed to access the details of the RaygunMessage object correctly.

For that I created methods to set_details and set_error.

As well, I created unit tests that check that what the documentation says is correct.

Finally, I also fixed the documentation formatting a bit.

This is potentially a breaking change if customers were accessing the object as a dictionary, as they will have to change the code, so a major version should be released.

While implementing this fix, I also made sure that functions are pure and that they don't modify the provided RaygunMessage, but rather modify a copy and then return it.

Type of change

fix: Bug fix (non-breaking change which fixes an issue)
feat: New feature (non-breaking change which adds functionality)
chore: Chore task, release or small impact change
ci: CI configuration change
Other type of change (specify)
Breaking change (fix or feature that would cause existing functionality to not work as expected)
This change requires a documentation update

    def _transform_message(self, message):

_transform_message should be pure and not modify the original message object

        if message is not None:

-            message["details"]["groupingKey"] = utilities.execute_grouping_key(
+            message.get_details()["groupingKey"] = utilities.execute_grouping_key(


message should be a RaygunMessage object and not a dict, access properties using accessors.

_post should be a pure function and not modify the original raygunMessage

+        updated_object.__dict__.update(iteration_target)
+        return updated_object
+


If the original object was a RaygunMessage, then we need to create a copy of the object and apply the changes to the internal __dict__

Pull Request Overview

This PR fixes a bug where the on_grouping_key callback received a raw dictionary instead of a RaygunMessage, and adjusts related methods to treat messages as immutable copies. It also updates tests, adds new setters/getters in RaygunMessage, and refines documentation.

Refactored filter_keys to detect and return a modified RaygunMessage instead of plain dict
Changed RaygunSender to use copy(), get_details(), set_details(), and set_error()
Added new getters/setters (get_error, get_details, set_details, set_error) and corresponding unit tests

The parameter name object shadows a Python built-in and is ambiguous. Consider renaming it to obj or target for clarity.

def filter_keys(filtered_keys, object):

We should add unit tests for the new set_error() and set_details() methods to ensure they correctly update the RaygunMessage state.

Add a test case where filter_keys is called on a RaygunMessage instance to verify it returns a RaygunMessage (not a dict) with filtered fields.

Pull Request Overview

This PR ensures that the on_grouping_key callback always receives a RaygunMessage object (not a raw dict), fixes the key‐filtering bug, updates internal message handling methods, and adds corresponding tests and documentation tweaks.

filter_keys now detects RaygunMessage, returns a modified copy, and preserves message methods.
Added set_details/set_error and updated _transform_message/_post to use get_details/get_error/set_* APIs.
Expanded unit tests for these changes and improved README code formatting.

[nitpick] Consider renaming the parameter 'filtered_keys' to 'keys_to_filter' for clearer intent, since 'filtered_keys' can be misread as keys already filtered.

def filter_keys(filtered_keys, obj):
