E.EntityFrameworkCore.Extensions
EntityFrameworkCore 的扩展库
功能
目前已经实现的功能:
- PostgreSql DbSet 表名、视图名、列名自动处理为小写
- Oracle DbSet 表名、视图名、列名自动处理为大写
- 自定义 DbSet 校验处理函数
- 自定义 DbQuery 校验处理函数
- 自定义 Column(Field) 校验处理函数
- 自定义列名长度,自动进行裁剪
- 自动跳过处理 DbContext 程序集中已实现的 IEntityTypeConfiguration
- 增加是否使用 DbSet/DbQuery 名称作为 表名称/视图名称 选项
- 增加字符串列设置默认数据长度 校验函数
基本用法
1. 引入nuget包
- dotnet cli
dotnet add package E.EntityFrameworkCore.Extensions
- nuget package manager
Install-Package E.EntityFrameworkCore.Extensions
2. 配置 DbContext
- 重写 DbContext的 OnModelCreating 函数
- 引入命名空间
using E;
3. 配置 E.EntityFrameworkCore.Extensions
以下代码均处于 OnModelCreating 函数中
PostgreSql
base.OnModelCreating(modelBuilder);
// 禁用 使用DbSet名称作为表名和视图名称,优先读Table标记,其次类名
E.EntityFrameworkCoreTableViewExtensions.UseDbSetNameToTableName = false;
// 设置小写
E.EntityFrameworkCoreTableViewExtensions.SetCaseType(modelBuilder, ColumnNameCaseType.Lower);
// 自定义要处理的字段类型,较多,此处不贴完整
E.EntityFrameworkCoreTableViewExtensions.DbMapTypes.Add("System.String[]");
E.EntityFrameworkCoreTableViewExtensions.DbMapTypes.Add("System.Boolean[]");
E.EntityFrameworkCoreTableViewExtensions.DbMapTypes.Add("System.Int32[]");
// 处理此数据库上下文类型中 DbSet
// 参数为 true,则 自动跳过处理 DbContext 程序集中已实现的 IEntityTypeConfiguration 的 DbSet<Entity>
modelBuilder.CaseAllDbSetNameAndColumnName<BloggingContext>(/* true */);
Oracle
base.OnModelCreating(modelBuilder);
// 禁用 使用DbSet名称作为表名和视图名称,优先读Table标记,其次类名
E.EntityFrameworkCoreTableViewExtensions.UseDbSetNameToTableName = false;
// 设置大写
E.EntityFrameworkCoreTableViewExtensions.SetCaseType(modelBuilder, ColumnNameCaseType.Upper);
// 使用列名长度限制,最大30
E.EntityFrameworkCoreTableViewExtensions.UseColumnNameMaxLength = true;
E.EntityFrameworkCoreTableViewExtensions.ColumnNameMaxLength = 30;
// 使用默认字符串长度
E.EntityFrameworkCoreTableViewExtensions.UseDefaultStringMaxLength = true;
E.EntityFrameworkCoreTableViewExtensions.DefaultStringMaxLength = 256;
// 自定义 字符串列数据长度 是否设置默认长度 校验函数
E.EntityFrameworkCoreTableViewExtensions.CheckUseDefaultStringMaxLength = (type, prop) =>
{
var checkResult = new CheckUseDefaultStringMaxLenghtResult();
// 如果实体的命名空间为 TestWebApp.Database.Models 则设置长度为200
if (type.Namespace.StartsWith("TestWebApp.Database.Models"))
{
checkResult.Success = true;
checkResult.MaxLength = 200;
}
return checkResult;
};
// 处理此数据库上下文类型中 DbSet
// 参数为 true,则 自动跳过处理 DbContext 程序集中已实现的 IEntityTypeConfiguration 的 DbSet<Entity>
modelBuilder.CaseAllDbSetNameAndColumnName<BloggingContext>(/* true */);
自定义校验处理函数
以下代码均处于 OnModelCreating 函数中
// DbSet Check
E.EntityFrameworkCoreTableViewExtensions.DbSetCheck = (info) =>
{
// 你的校验逻辑
return true;// or false
};
// Column Chcek
E.EntityFrameworkCoreTableViewExtensions.ColumnCheck = (info) =>
{
// 你的校验逻辑
return true;// or false
};
