英文:
SaveChangesOnDbContextAsync has never been called
问题
ABP已添加了一个可重写的函数，名为SaveChangesOnDbContextAsync，允许我们拦截任何插入/更新/删除操作，具体信息请参见此链接：https://github.com/abpframework/abp/issues/4659
我尝试重写SaveChangesOnDbContextAsync，在一个继承自AbpDbContext的类中，就像以下示例一样，但无论我何时更新数据，它都从未被调用：
public override async Task<int> SaveChangesOnDbContextAsync(bool acceptAllChangesOnSuccess, CancellationToken cancellationToken = default)
{
var result = await base.SaveChangesAsync();
return result;
}
英文:
ABP has added an overridable function called SaveChangesOnDbContextAsync that allow us to intercept any insert/update/delete operation as in this link: https://github.com/abpframework/abp/issues/4659
I tried to override SaveChangesOnDbContextAsync in a class that inherits AbpDbContext like the following but it has never been called whenever I update the data:
public override async Task<int> SaveChangesOnDbContextAsync(bool acceptAllChangesOnSuccess, CancellationToken cancellationToken = default)
{
var result = await base.SaveChangesAsync();
return result;
}

得分: 0
这个方法是为了让你的应用程序代码绕过AbpDbContext.SaveChangesAsync()中的逻辑而提供的。ABP不会调用它。
这是请求者的意思：
public override async Task<int> SaveChangesAsync(bool acceptAllChangesOnSuccess, CancellationToken cancellationToken = default)
{
try
{
return await base.SaveChangesAsync(acceptAllChangesOnSuccess, cancellationToken);
}
catch (AbpDbConcurrencyException)
{
// 处理它
// ...
// 直接调用Microsoft.EntityFrameworkCore.DbContext的SaveChangesAsync(bool, CancellationToken)，以避免反复创建审计日志、更新并发标记或触发实体事件等，就像AbpDbContext的版本所做的那样
return await base.SaveChangesOnDbContextAsync(acceptAllChangesOnSuccess, cancellationToken);
}
}
你可能只需要重写SaveChangesAsync。
英文:
That method is provided for your application code to bypass the logic in AbpDbContext.SaveChangesAsync(). ABP does not call it.
This is what the requestor meant:
public override async Task<int> SaveChangesAsync(bool acceptAllChangesOnSuccess, CancellationToken cancellationToken = default)
{
try
{
return await base.SaveChangesAsync(acceptAllChangesOnSuccess, cancellationToken);
}
catch (AbpDbConcurrencyException)
{
// Handle it
// ...
// Directly call Microsoft.EntityFrameworkCore.DbContext's SaveChangesAsync(bool, CancellationToken) to not repeatedly
// create audit logs, update concurrencystamps, or trigger entity events etc. as AbpDbContext's version would do
return await base.SaveChangesOnDbContextAsync(acceptAllChangesOnSuccess, cancellationToken);
}
}
You probably just want to override SaveChangesAsync instead.
