366-369: LGTM! Verify array matching behavior.
The integration of _match_arrays into the pipeline looks correct and should fix the null responses for min/max queries on array fields.
Let's verify the fix works for nested arrays:
✅ Verification successful
Array matching implementation is consistent with codebase patterns
The verification shows that:
- The
$unwindoperation is consistently used across the codebase for array handling - The new
_match_arraysimplementation follows similar patterns seen in other MongoDB pipeline builders - Array field handling is properly integrated with frame fields through
is_frame_fieldchecks - The implementation aligns with existing array operations in core modules like
collections.py,view.py, andaggregations.py
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Check for similar array matching patterns in the codebase
# to ensure consistent handling across different query types
# Look for other MongoDB pipeline builders that might need similar array matching
rg -l 'append.*\$match.*\$exists' --type py
# Look for test files that verify array queries
rg -l 'test.*array.*query' --type py
Length of output: 113
Script:
#!/bin/bash
# Let's look for array-related test cases and MongoDB pipeline patterns more broadly
# Search for array-related test cases with different patterns
rg -l "test.*array" tests/
rg -l "array.*test" tests/
# Look for MongoDB pipeline patterns with array operations
rg -A 5 '\$unwind|\$match.*array' --type py
# Check the implementation of _match_arrays function
rg -A 10 '_match_arrays' fiftyone/server/lightning.py
# Look for similar array handling patterns
rg -A 5 'is_frame_field.*pipeline' --type py
