Add ToJson() configuration for complex collections in EF Core 10 by Copilot · Pull Request #123 · microting/Pomelo.EntityFrameworkCore.MySql

Copilot · 2025-11-17T17:07:17Z

Fix ToJson configuration for complex collection properties in EF Core 10

Summary

Added .ToJson() configuration for complex collection properties across multiple test files to comply with EF Core 10 requirements. Complex collections must be explicitly mapped to JSON columns using .ToJson() without explicit column type specification.

Changes Completed

Analyzed error: "The complex collection property 'FieldPubWithCollections.Activities' must be mapped to a JSON column"
Added .ToJson() configurations in ComplexTypesTrackingMySqlTest for 7 entity types
Added .ToJson() configuration in ComplexCollectionJsonMySqlTest
Added OnModelCreating override in PropertyValuesMySqlTest to configure School.Departments
Resolved column type specification issue: removed .HasColumnType("json") as it's not supported when chained with .ToJson() for complex collections
Build verification successful

Files Modified

test/EFCore.MySql.FunctionalTests/ComplexTypesTrackingMySqlTest.cs
- Added .ToJson() configuration to 7 entity types with complex collections
- Pattern: .ComplexCollection(e => e.Activities, b => b.ToJson())
test/EFCore.MySql.FunctionalTests/ComplexCollectionJsonMySqlTest.cs
- Fixed incorrect use of ComplexProperty() → ComplexCollection().ToJson()
- Pattern: .ComplexCollection(e => e.Departments).ToJson()
test/EFCore.MySql.FunctionalTests/PropertyValuesMySqlTest.cs (NEW)
- Added OnModelCreating override in PropertyValuesMySqlFixture
- Configured School entity: .ComplexCollection(e => e.Departments, b => b.ToJson())

Technical Details

In EF Core 10, complex collections (collections of complex types) must be explicitly mapped to JSON columns using .ToJson(). The configuration should not include .HasColumnType() when used with complex collections, as the provider determines the appropriate column type automatically.

This matches the pattern from EF Core's base relational tests (ComplexTypesTrackingRelationalTestBase.cs) which use .ToJson() without explicit column type specification.

Fixed in bc2aac2. Added .HasColumnType("json") to all .ToJson() configurations. MySQL requires explicit JSON column type specification - the base EF Core relational tests don't specify it because different providers use different store types.
