也可以使用由累积对象和累积金额组成的累加器使用使用?

const keys = ['a', 'b', 'c'];
const amount = 300;
const percentage = 0.5;

const obj = keys.reduce(({obj, amount}, key) => (
    obj[key] = amount, {obj, amount: amount * (1 + percentage)}
), {obj: {}, amount}).obj;

console.log(obj); //{a: 300, b: 450, c: 675}

Maybe use reduce with an accumulator that consists of the accumulated object and the accumulated amount?

const keys = ['a', 'b', 'c'];
const amount = 300;
const percentage = 0.5;

const obj = keys.reduce(({obj, amount}, key) => (
    obj[key] = amount, {obj, amount: amount * (1 + percentage)}
), {obj: {}, amount}).obj;

console.log(obj); //{a: 300, b: 450, c: 675}

按以前值的百分比按数组

您可以流式list BillingAccount,然后使用汇总操作filter确保每个billingAcccount嵌套的场不是较短条件的零。最后,收集每个键是billingAccount的标识符的结果,而相应的值是对象本身。

Map<String, BillingAccount> billingAccountsMap = billingAccounts.stream()
        .filter(ba -> Objects.nonNull(ba) 
                && Objects.nonNull(ba.getBillingAccountIdentifier()) 
                && Objects.nonNull(ba.getBillingAccountIdentifier().getIdentifier()))
        .collect(Collectors.toMap(ba -> ba.getBillingAccountIdentifier().getIdentifier(), Function.identity()));

You could stream your List of BillingAccount, then use the aggregate operation filter to make sure that each BillingAccount and its nested fields are not null with a short-circuited condition. Finally, collect the results where each key is the BillingAccount's identifier while the corresponding value is the object itself.

Map<String, BillingAccount> billingAccountsMap = billingAccounts.stream()
        .filter(ba -> Objects.nonNull(ba) 
                && Objects.nonNull(ba.getBillingAccountIdentifier()) 
                && Objects.nonNull(ba.getBillingAccountIdentifier().getIdentifier()))
        .collect(Collectors.toMap(ba -> ba.getBillingAccountIdentifier().getIdentifier(), Function.identity()));

如果要访问组织中的ID,请尝试以下操作:

x = x.json()
print(x["organization"]["id"])

If you want to access the ID in the Organization try this:

x = x.json()
print(x["organization"]["id"])

解决方案:后来我发现Angular.json中存在引导的参考。我从Angular.json删除了这些引用,然后再次构建了解决方案。现在工作正常。

Solution: Later I found that there are references of bootstrap present in angular.json. I removed those references from angular.json and built the solution again. Working fine now.

您要做以下操作:

res = [endpoint['vlan'] for item in data if item["connections"] for endpoint in item["connections"]["endpoints"] if endpoint['id']== "ee0d38d3-89fb-4e5b-b9bd-83ee554949ab"]

如果您需要唯一的VLAN值,则可以使用

list(set(res))

You do something like below:

res = [endpoint['vlan'] for item in data if item["connections"] for endpoint in item["connections"]["endpoints"] if endpoint['id']== "ee0d38d3-89fb-4e5b-b9bd-83ee554949ab"]

and if you need unique vlan values you can use

list(set(res))

您正在打电话给 > ,它本身就是延迟函数中的Dask操作。因此,当您调用result.com pupute时,您正在执行函数calc_avg平均值。但是,calc_avg返回DASK支持的数据。是的,17S任务将计划的延迟 calc_avgearne的dask图将其定为计划dask.array open_mfdataset和Array OPS的DASK图。

要解决此问题,请放下延迟的包装器,然后简单地使用dask.Array Xarray工作流程:

a = calc_avg(p1)  # this is already a dask array because
                  # calc_avg calls open_mfdataset
b = calc_avg(p2)  # so is this
total = a - b     # dask understands array math, so this "just works"
result = total.compute()    # execute the scheduled job

请参阅 xarray指南与dask的并行计算指南进行简介。

You’re wrapping a call to xr.open_mfdataset, which is itself a dask operation, in a delayed function. So when you call result.compute, you’re executing the functions calc_avg and mean. However, calc_avg returns a dask-backed DataArray. So yep, the 17s task converts the scheduled delayed dask graph of calc_avg and mean into a scheduled dask.array dask graph of open_mfdataset and array ops.

To resolve this, drop the delayed wrappers and simply use the dask.array xarray workflow:

a = calc_avg(p1)  # this is already a dask array because
                  # calc_avg calls open_mfdataset
b = calc_avg(p2)  # so is this
total = a - b     # dask understands array math, so this "just works"
result = total.compute()    # execute the scheduled job

See the xarray guide to parallel computing with dask for an introduction.

用Xarray -Compute()结果延迟的dask仍然延迟

在您当前的数据结构上,您需要在开始结束上执行范围过滤器,以确定事件是否属于一个月。如Firestore的 query limitations 就是不可能:

在复合查询中,范围(&lt;&lt; =&gt;&gt; =)而不是等于(!=not-In-in)比较必须在同一字段上进行过滤。

为了允许查询,一种解决方案是在活动中的所有月份中添加一个数组字段,以便您可以在此上使用Array-Contains过滤器。

On your current data structure you will need to perform a range filter on both start and end to determine whether the event falls into a certain month. As shown in the documentation on Firestore's query limitations, that is not possible:

In a compound query, range (<, <=, >, >=) and not equals (!=, not-in) comparisons must all filter on the same field.

To allow the query, one solution would be to add an array field with all the months that the event is active in, so that you can then use an array-contains filter on that.

您可以为此使用指标约束。例如:

δ = δ1+δ2
δ = 0 => x=y
δ1 = 1 => x≥y+1
δ2 = 1 => y≥x+1
δ,δ1,δ2 ∈ {0,1}

 

You could use indicator constraints for that. E.g.:

δ = δ1+δ2
δ = 0 => x=y
δ1 = 1 => x≥y+1
δ2 = 1 => y≥x+1
δ,δ1,δ2 ∈ {0,1}

 

SCIP手柄会自动划分0吗?

您应该能够在SQL Server 2016中使用string_split(),除了在两种情况下:

  1. 如果您未正确调用该函数 - 许多人试图称其为标量函数(> code>)选择string_split(...),而不是表值函数(select * select * from String_split(...)。它返回表格,因此您必须像表一样对待它。
  2. 如果您的数据库的兼容性级别低于130。这被称为在文档的顶部,我在在您无法更改campat级别的情况下

>无论如何都不会解决此问题...

...因为不能保证输出顺序,因此您永远无法可靠地确定哪个元素是第三个元素。

从我在,您可以创建以下简单函数:

CREATE FUNCTION dbo.SplitOrdered_JSON
(
  @List      nvarchar(4000),
  @Delimiter nvarchar(255)
)
RETURNS table WITH SCHEMABINDING
AS
  RETURN
  (
    SELECT [key], value FROM OPENJSON
    (
      CONCAT
      (
        N'["',
        REPLACE(STRING_ESCAPE(@List, 'JSON'), 
          @Delimiter, N'","'),
        N'"]')
      ) AS x
    );

然后,如果您追求字符串中的第三次元素,则可以在解析前反转,然后在解析后再次反转。例如,

CREATE TABLE #f(ID int, FullFilePath nvarchar(4000));

INSERT #f VALUES
(1,N'Y:\dfs-dc-01\Split\Retail\Kroger\Kroger\FTP-FromClient\Oracle\2022-05-04\MSudaitemlov_20220503'),
(2,N'Y:\dfs-dc-01\Split\Retail\Kroger\Kroger\FTP-FromClient\OracleABC\2022-05-04\FDERDMSudaitemlov_20220503'),
(3,N'Y:\dfs-dc-01\Split\Retail\Kroger\Kroger\FTP-FromClient\OCSBAGF\2022-05-04\AASSSMSudaitemlov_20220503');

DECLARE @ElementOfInterest int = 3;

SELECT REVERSE(value) 
  FROM #f CROSS APPLY dbo.SplitOrdered_JSON(REVERSE(FullFilePath), N'\')
  WHERE [key] = @ElementOfInterest - 1;
  • 示例

You should be able to use STRING_SPLIT() in SQL Server 2016, except in two scenarios:

  1. If you're not calling the function correctly - many people try to call it like a scalar function (SELECT STRING_SPLIT(...) instead of a table-valued function (SELECT * FROM STRING_SPLIT(...). It returns a table, so you must treat it like a table.
  2. If your database's compatibility level is lower than 130. This is called out at the very top of the documentation, and I've given several workarounds in this tip in cases where you can't change compat level.

But STRING_SPLIT() won't solve this problem anyway...

...because the output order is not guaranteed, so you could never reliably determine which element is 3rd from last.

Borrowing shamelessly from my work in this article, you can create the following simple function:

CREATE FUNCTION dbo.SplitOrdered_JSON
(
  @List      nvarchar(4000),
  @Delimiter nvarchar(255)
)
RETURNS table WITH SCHEMABINDING
AS
  RETURN
  (
    SELECT [key], value FROM OPENJSON
    (
      CONCAT
      (
        N'["',
        REPLACE(STRING_ESCAPE(@List, 'JSON'), 
          @Delimiter, N'","'),
        N'"]')
      ) AS x
    );

Then if you're after the 3rd-last element in the string, you can just reverse before parsing, and then reverse again after parsing. e.g.

CREATE TABLE #f(ID int, FullFilePath nvarchar(4000));

INSERT #f VALUES
(1,N'Y:\dfs-dc-01\Split\Retail\Kroger\Kroger\FTP-FromClient\Oracle\2022-05-04\MSudaitemlov_20220503'),
(2,N'Y:\dfs-dc-01\Split\Retail\Kroger\Kroger\FTP-FromClient\OracleABC\2022-05-04\FDERDMSudaitemlov_20220503'),
(3,N'Y:\dfs-dc-01\Split\Retail\Kroger\Kroger\FTP-FromClient\OCSBAGF\2022-05-04\AASSSMSudaitemlov_20220503');

DECLARE @ElementOfInterest int = 3;

SELECT REVERSE(value) 
  FROM #f CROSS APPLY dbo.SplitOrdered_JSON(REVERSE(FullFilePath), N'\')
  WHERE [key] = @ElementOfInterest - 1;

我想知道是否有一个原因您无法使用这种方法: a>

然后,您可以简单地使用请求参数来修改响应。

如果您真的想以这种方式工作,看来您没有正确地遵循该示例。

您需要覆盖您的货币介药类内的静态集合方法:

public static function collection($resource){
   return new CurrencyResourceCollection($resource);
}

您还需要创建货币resourcollection类并在该类上定义showdefaultImage方法和$ show_default_image属性,如您所介绍的示例。

那么您应该能够做到:这样

CurrencyResource::collection($currencies)->showDefaultImage(true);

做的方式不起作用,是因为您还没有在资源上定义静态集合方法,因此它默认为返回默认集合对象的正常行为在您的错误消息中查看。

I wonder if there is a reason you can't use this approach: https://stackoverflow.com/a/51689732/8485567

Then you can simply use the request parameters to modify your response.

If you really want to get that example working in that way, it seems you are not following the example correctly.

You need to override the static collection method inside your CurrencyResource class:

public static function collection($resource){
   return new CurrencyResourceCollection($resource);
}

You also need to create the CurrencyResourceCollection class and define the showDefaultImage method and $show_default_image property on that class as in the example you referred to.

Then you should be able to do:

CurrencyResource::collection($currencies)->showDefaultImage(true);

The reason the way you are doing it doesn't work is because you haven't defined the static collection method on your resource hence it's defaulting to the normal behavior of returning a default collection object as you can see in your error message.

为什么在资源收集提出的错误中使用添加剂参数?
