Problem

The strip_whitespace option was not working for group conditions in Ransack searches. While whitespace stripping worked correctly for top-level conditions, it was ignored when using grouped conditions with the g: parameter.

For example, this search would not strip whitespace from the values:

User.ransack({g: [{name_cont: "  John  ", email_cont: "  john@example.com  ", m: "or"}]})

The values " John " and " john@example.com " would retain their leading/trailing whitespace even when strip_whitespace was enabled globally or passed as an option.

Root Cause

The whitespace stripping logic was only implemented in Search#initialize at the top level. When group conditions were processed, they went through the Grouping#build method which didn't have access to the strip_whitespace option, so nested conditions never had their whitespace stripped.

Solution

This fix implements a minimal change to pass the strip_whitespace option down to nested groupings:

1. Added strip_whitespace attribute to Context: The base Context class now stores the strip_whitespace setting so it's available to all nested operations.

2. Set context strip_whitespace in Search: The Search#initialize method now sets the strip_whitespace option on the context after determining it from options or global config.

3. Enhanced Grouping#build with whitespace stripping: The Grouping#build method now applies whitespace stripping recursively when strip_whitespace is enabled.

4. Added recursive helper method: A new strip_whitespace_from_params method handles stripping whitespace from nested Hash, Array, and String structures.

Testing

• Added comprehensive tests covering both strip_whitespace: true and strip_whitespace: false scenarios for group conditions
• All existing tests continue to pass (464 examples, 0 failures)
• Manual testing confirms the original issue example now works correctly

Example

After this fix, the following now works as expected:

# Whitespace is now properly stripped from group condition values
search = User.ransack(
  {g: [{name_cont: "  John  ", email_cont: "  john@example.com  ", m: "or"}]}, 
  {strip_whitespace: true}
)

# Values are now "John" and "john@example.com" (stripped)

The fix maintains full backward compatibility and respects both global Ransack.options[:strip_whitespace] configuration and per-search strip_whitespace: false options.

Fixes the issue where group conditions didn't respect the strip_whitespace setting.

Closing as part of clearing the PR backlog ahead of 5.0.0 (#1640).

This is one of a batch of PRs opened by the Copilot coding agent in September 2025. They have aged out: main has moved on substantially since (Rails 8.1 support, the CI matrix rework in #1667, the v5.0.0 branch consolidation in #1647), and most of these either no longer apply cleanly, no longer pass, or carry specs that don't run under the project's _spec.rb pattern.

The underlying issue stays open. Nothing is being dismissed on the merits — the bug reports behind these PRs are still valid and still wanted. What's being retired is a batch of stale machine-generated branches that cost more to salvage than to redo.

If you're affected by the underlying issue, the most useful contribution is a PR with a failing spec that reproduces it against current main — see CONTRIBUTING.md.
