项目场景：

ABP项目执行数据库迁移

问题描述：

Unable to determine the relationship represented by navigation 'XXX' of type 'XXX'. Either manually configure the relationship, or ignore this property using the '[NotMapped]' attribute or by using 'EntityTypeBuilder.Ignore' in 'OnModelCreating'.

原因分析：

在XXXDbContext中OnModelCreating 下缺少对初始化的配置。

解决方案：

/// <summary>
/// Fluent API
/// </summary>
public class UserEntityConfig : IEntityTypeConfiguration<User>
{public void Configure(EntityTypeBuilder<User> builder){// ......}
}


protected override void OnModelCreating(ModelBuilder modelBuilder)
{base.OnModelCreating(modelBuilder);//继承自IEntityTypeConfiguration<>的各实体 Fluent APImodelBuilder.ApplyConfigurationsFromAssembly(typeof(XXXCoreModule).Assembly);
}
