abp-vnext-pro 實戰（四，給客戶表增加多租戶）

XXXHttpApiHostModule 裏面默認啓用多租戶

        public override void OnApplicationInitialization(ApplicationInitializationContext context)
        {
            var app = context.GetApplicationBuilder();

            。。。

            if (MultiTenancyConsts.IsEnabled)
            {
                app.UseMultiTenancy();
            }

 

增加多租戶很簡單，domain類裏實現IMultiTenant接口就可以了

 Customer : FullAuditedAggregateRoot<Guid>, IMultiTenant

 在瀏覽器標頭可以看到

 

        public async Task<List<Customer>> GetListAsync(int maxResultCount = 10, int skipCount = 0,
            string filter=null)
        {


        return await (await GetDbSetAsync())
                .WhereIf(!filter.IsNullOrWhiteSpace(),
                x => x.Name.Contains(filter))
                .OrderByDescending(e => e.CreationTime)
                .PageBy(skipCount, maxResultCount)
                .ToListAsync();
        }

不能這樣寫

        //unable to cast object of type
        //'microsoft.entityframeworkcore.query.internal.entityqueryable`1[fox.erp.domain.customer]'
        //to type 'microsoft.entityframeworkcore.dbset`

.WhereIf(!filter.IsNullOrWhiteSpace(),
                (Customer x) => x.Name.Contains(filter))

 

不要在Domain 項目裏的CustomerManager.cs裏的UpdateAsync 加上TenantId字段，這個由系統維護！！！

也不需要在DTO裏維護！！！
