7 years ago Answer

I override OnModelCreating, then I got an error when Add-Migration.

Error message is below

"Unable to determine the relationship represented by navigation property 'User.DeleterUser' of type 'User'. Either manually configure the relationship, or ignore this property from the model."

P.S. I Include module zero (the current version)

Pomelo.EntityFrameworkCore.MySql is work fine.

after abpusertokens table created, then throw exception below.

I think mysql not support Length: 2000 Value = table.Column

migrationBuilder.CreateTable(
                name: "AbpSettings",
                columns: table => new
                {
                    Id = table.Column&lt;long&gt;(nullable: false)
                        .Annotation("MySql:ValueGeneratedOnAdd", true),
                    CreationTime = table.Column&lt;DateTime&gt;(nullable: false),
                    CreatorUserId = table.Column&lt;long&gt;(nullable: true),
                    LastModificationTime = table.Column&lt;DateTime&gt;(nullable: true),
                    LastModifierUserId = table.Column&lt;long&gt;(nullable: true),
                    Name = table.Column&lt;string&gt;(maxLength: 256, nullable: false),
                    TenantId = table.Column&lt;int&gt;(nullable: true),
                    UserId = table.Column&lt;long&gt;(nullable: true),
                    Value = table.Column&lt;string&gt;(maxLength: 2000, nullable: true)
                },
                constraints: table =>
                {
                    table.PrimaryKey("PK_AbpSettings", x => x.Id);
                    table.ForeignKey(
