Answer 2

我不确定您要做什么，但是也许使用CustomListItem创建列表或Treelist会为您提供更多帮助。
您可以将其放入SplitApp中，并具有“导航”面板，但可以完全自定义。

Answer 3

这很简单。 可以使用 column（）使用 mainaxisAlignment mainaxisalignment.center.center ：

Column(
      mainAxisAlignment: MainAxisAlignment.center,
      children: [
        Text(
          "P O M O D O N E",
          style: TextStyle(
            fontWeight: FontWeight.bold,
            fontSize: 22,
            color: Color(0xff313640),
          ),
        ),
        Text('click me')
      ],
    )

由于您想要一个小部件下方的一个小部件，因此 要删除 center（）窗口小部件代替 column（）。

使用您的代码，一个完整的可运行示例：

import 'package:braintrinig/pages/log_in.dart';
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';

class HomePage extends StatelessWidget {
  const HomePage({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: Color(0xffF24004),
      body: Center(
        child: Container(
          child: Column(
            crossAxisAlignment: CrossAxisAlignment.center,
            mainAxisAlignment: MainAxisAlignment.center,
            children: [
              GestureDetector(
                onTap: () {
                  print("Container clicked");
                  Navigator.pushReplacement(
                      context, MaterialPageRoute(builder: (_) => LogIn()));
                },
                child: Container(

                      ),),
                      Text('Click me')
                    ],
                  ),
                ),
              ),
              Center(

                  crossAxisAlignment: CrossAxisAlignment.center,
                  mainAxisAlignment: MainAxisAlignment.center,
                  children: [
                    Container(
                      width: 75,
                      height: 112,
                      child: Icon(Icons.check_rounded,
                        size: 100,
                        color: Color(0xffF3F5F4),
                      ),
                    ),
                  ],
                ),

Answer 4

不，您不能使用 sizeof（ptr）查找数组的大小 ptr 指向。

尽管要在额外的空间中存储长度，但分配额外的内存（大于数组的大小）将有所帮助。

Answer 5

一种选项是，您可以将REGEX与 split（）方法一起使用，或者使用 match（）方法而不是使用Regex。正则表达式将根据您选择使用的方法而有所不同。

const data = `with(document)with(body)with(insertBefore(createElement("script"),firstChild))setAttribute("exparams","userid=&aplus&ali_beacon_id=&ali_apache_id=&ali_apache_track=&ali_apache_tracktmp=&dmtrack_c={}&hn=aeproductsourcesite033001217071%2eus44&asid=AQAAAADkyhRi8NcdZwAAAABHROT4NDi+yA==&sidx=Fzc+BeTKFGIAAAAA0uvd1jNUkicntMPM",id="beacon-aplus",src="//assets.alicdn.com/g/alilog/??aplus_plugin_aefront/index.js,mlog/aplus_v2.js")

const removeWithSplit = (data) => data.split(/(\n|\r){2,}/).pop();

const removeWithMatch = (data) => data.match(/(\w\s?)+:.*/g)?.join('\n');

console.log('**WITH SPLIT**');
console.log(removeWithSplit(data), '\n');

console.log('**WITH MATCH**');
console.log(removeWithMatch(data), '\n');

奖励：

这是一个api返回此纯文本的bummer。可以改用JSON吗？如果没有，这是一种将其结果转换为对象的方法：

const data = `with(document)with(body)with(insertBefore(createElement("script"),firstChild))setAttribute("exparams","userid=&aplus&ali_beacon_id=&ali_apache_id=&ali_apache_track=&ali_apache_tracktmp=&dmtrack_c={}&hn=aeproductsourcesite033001217071%2eus44&asid=AQAAAADkyhRi8NcdZwAAAABHROT4NDi+yA==&sidx=Fzc+BeTKFGIAAAAA0uvd1jNUkicntMPM",id="beacon-aplus",src="//assets.alicdn.com/g/alilog/??aplus_plugin_aefront/index.js,mlog/aplus_v2.js")

            [key]: value,
        };
    }, {} as Record<string, unknown>);
};

console.log(resultsToObject(removeWithMatch(data) as string));

Answer 6

问题在这里：

    bookmaker.markets[0].outcomes.forEach(outcome => {
      matchesAndOdds[i].odds[bookmaker.title] = {};

这将重置奇数[bookmaker.title] 在每次迭代中， utemes 中的对象。这将破坏该循环先前迭代的结果。此初始化应该在循环之前发生：

    matchesAndOdds[i].odds[bookmaker.title] = {};
    bookmaker.markets[0].outcomes.forEach(outcome => {

您实际上可以用“更好”的代码进行过程：

const odds =[{"id": "dd7aff0584aee475b4d67ab83655f379","sport_key": "aussierules_afl","sport_title": "AFL","commence_time": "2022-06-30T09:20:00Z","home_team": "Brisbane Lions","away_team": "Western Bulldogs","bookmakers": [{"key": "unibet","title": "Unibet","last_update": "2022-06-29T12:14:33Z","markets": [{"key": "h2h","outcomes": [{"name": "Brisbane Lions","price": 1.36},{"name": "Western Bulldogs","price": 3.15}]}]}]}]
const matches =[{gametime: "2022-06-30T09:20:00.000Z",home_team: 'Brisbane Lions',away_team: 'Western Bulldogs',ground: 'Gabba',home_points: 108,away_points: 67,selected: null}]
const ffToOa = {"Western Bulldogs": "Western Bulldogs","Brisbane Lions": "Brisbane Lions","St Kilda": "St Kilda Saints","Carlton": "Carlton Blues","Sydney": "Sydney Swans","Essendon": "Essendon Bombers","Melbourne": "Melbourne Demons","Naarm": "Melbourne Demons","Adelaide": "Adelaide Crows","North Melbourne": "North Melbourne Kangaroos","Geelong": "Geelong Cats","Collingwood": "Collingwood Magpies","Gold Coast": "Gold Coast Suns","West Coast": "West Coast Eagles","Richmond": "Richmond Tigers","Hawthorn": "Hawthorn Hawks","GWS": "Greater Western Sydney Giants","Port Adelaide": "Port Adelaide Power","Fremantle": "Fremantle Dockers"}

const matchesAndOdds = matches.map(match => {
  const {home_team, bookmakers} = odds.find(odd =>
    odd.home_team === ffToOa[match.home_team] &&
    odd.away_team === ffToOa[match.away_team]
  ) ?? {};
  return home_team ? {
    ...match, 
    odds: Object.fromEntries(bookmakers.map(({title, markets: [{outcomes}]}) => [
      title,
      Object.fromEntries(outcomes.map(outcome =>
        [outcome.name === home_team ? "home" : "away", outcome.price]
      ))
    ]))
  } : match;
});

console.log(matchesAndOdds);

Answer 7

我已经处理了以下错误，以“ typeorm”：“ 0.3.6”，以前，因此希望我的经验与您相关。

而不是使用 getManager 我正在使用 entityManager ，但结果是相同的。

这是您的情况的示例：

test.module.ts

@Module({
  imports: [
    TypeOrmModule.forRoot(postgresConfig), // <- connection configs
    TypeOrmModule.forFeature([
      TestEntity,
    ]),
  ],
  controllers: [],
  providers: [TestService],
})
export class TestModule {}

test.service.ts

@Injectable()
export class TestService implements OnApplicationBootstrap {
  constructor(
    @InjectEntityManager()
    private readonly entityManager: EntityManager,
  )

  async onApplicationBootstrap(): Promise<void> {
    const count = await this.entityManager.getRepository(TestEntity).count('query');
    console.log(count);
  }
}

您还应该为此创建一个Typeorm实体。

如果我们谈论迁移，则可以使用 ormconfig.json ，但使用TypeOmm与Jest等测试框架相结合的问题，如果您与之相关，只需提及它，并且我会在项目中找到一个例子。

它应该与没有装饰器的无需装饰的手动连接有关：

export const getDatabaseConnectionOptions = (config): PostgresConnectionOptions => {
    return {
        type: 'postgres',
        logging: config.db.logging,
        connectTimeoutMS: config.db.master.connectionTimeoutMillis,
        uuidExtension: 'uuid-ossp',
        extra: {
            idleTimeoutMillis: config.db.master.idleTimeoutMillis,
            max: config.db.master.max,
            keepalives_idle: config.db.master.keepalives_idle,
        },
        entities: process.env.TS_NODE
            ? [path.join(process.cwd(), 'src/**/*.entity.ts')]
            : [path.join(process.cwd(), 'dist/**/*.entity.js')],
        migrations: process.env.TS_NODE ? ['src/typeorm_migrations/*.ts'] : ['dist/typeorm_migrations/*.js'],
        migrationsTableName: 'typeorm_migrations',
        namingStrategy: new DatabaseNamingStrategy(),
        replication: {
            master: {
                host: config.db.master.host,
                port: config.db.master.port,
                username: config.db.master.user,
                password: config.db.master.password,
                database: config.db.master.database,
            },
            slaves: [
                {
                    host: config.db.slave.host,
                    port: config.db.slave.port,
                    username: config.db.slave.user,
                    password: config.db.slave.password,
                    database: config.db.slave.database,
                },
            ],
        },
        cli: {
            migrationsDir: 'src/typeorm_migrations',
        },
    };
};

export const createDatabaseConnection = async (config): Promise<Connection> => {
    // Setup TypeDI
    useContainer(Container);

    // Setup typeorm-transactional-cls-hooked
    initializeTransactionalContext();
    patchTypeORMRepositoryWithBaseRepository();

    return await createConnection(config);
};

    const connection = await createDatabaseConnection(getDatabaseConnectionOptions(config));
    const { app } = createAppApi();

然后通过 Connection props访问经理或实体。

目前，直到EFCORE有新的东西，我才会使用命令
并将其手动绘制

  using (var command = this.DbContext.Database.GetDbConnection().CreateCommand())
  {
      command.CommandText = "SELECT ... WHERE ...> @p1)";
      command.CommandType = CommandType.Text;
      var parameter = new SqlParameter("@p1",...);
      command.Parameters.Add(parameter);

      this.DbContext.Database.OpenConnection();

      using (var result = command.ExecuteReader())
      {
         while (result.Read())
         {
            .... // Map to your entity
         }
      }
  }

尝试SQLPARAMETER，以避免注入SQL。

 dbData.Product.FromSql("SQL SCRIPT");

FROFSQL无法使用完整查询。例如，如果要包含一个Were子句，它将被忽略。

Answer 10

即使您缺少对，也不需要排序（ as.matrix（dat1）[，1：2] 可以用 cbind（dat1 [，1]，， dat1 [，2]））：

> set.seed(45);dat1=data.frame(name=rep(c("firstName","secondName"),each=4),numbers=rep(1:4,2),value=rnorm(8))
> u1=unique(dat1[,1]);u2=unique(dat1[,2])
> m=matrix(nrow=length(u1),ncol=length(u2),dimnames=list(u1,u2))
> m[as.matrix(dat1)[,1:2]]=dat1[,3]
> m
                    1          2          3          4
firstName   0.3407997 -0.7033403 -0.3795377 -0.7460474
secondName -0.8981073 -0.3347941 -0.5013782 -0.1745357

如果您缺少对并且需要排序，这是不起作用的，但是如果对已经进行了排序，则有点短：

> u1=unique(dat1[,1]);u2=unique(dat1[,2])
> dat1=dat1[order(dat1[,1],dat1[,2]),] # not actually needed in this case
> matrix(dat1[,3],length(u1),,T,list(u1,u2))
                    1          2          3          4
firstName   0.3407997 -0.7033403 -0.3795377 -0.7460474
secondName -0.8981073 -0.3347941 -0.5013782 -0.1745357

这是第一个方法的函数版本（添加） as.data.frame 使其与tibbles一起使用）：

l2w=function(x,row=1,col=2,val=3,sort=F){
  u1=unique(x[,row])
  u2=unique(x[,col])
  if(sort){u1=sort(u1);u2=sort(u2)}
  out=matrix(nrow=length(u1),ncol=length(u2),dimnames=list(u1,u2))
  out[cbind(x[,row],x[,col])]=x[,val]
  out
}

或者，如果您只有下三角的值，则可以做到这一点：

> euro=as.matrix(eurodist)[1:3,1:3]
> lower=data.frame(V1=rownames(euro)[row(euro)[lower.tri(euro)]],V2=colnames(euro)[col(euro)[lower.tri(euro)]],V3=euro[lower.tri(euro)])
> lower
         V1        V2   V3
1 Barcelona    Athens 3313
2  Brussels    Athens 2963
3  Brussels Barcelona 1318
> n=unique(c(lower[,1],lower[,2]))
> full=rbind(lower,setNames(lower[,c(2,1,3)],names(lower)),data.frame(V1=n,V2=n,V3=0))
> full
         V1        V2   V3
1 Barcelona    Athens 3313
2  Brussels    Athens 2963
3  Brussels Barcelona 1318
4    Athens Barcelona 3313
5    Athens  Brussels 2963
6 Barcelona  Brussels 1318
7    Athens    Athens    0
8 Barcelona Barcelona    0
9  Brussels  Brussels    0
> l2w(full,sort=T)
          Athens Barcelona Brussels
Athens         0      3313     2963
Barcelona   3313         0     1318
Brussels    2963      1318        0

或以下是另一种方法：

> rc=as.matrix(lower[-3])
> n=sort(unique(c(rc)))
> m=matrix(0,length(n),length(n),,list(n,n))
> m[rc]=lower[,3]
> m[rc[,2:1]]=lower[,3]
> m
          Athens Barcelona Brussels
Athens         0      3313     2963
Barcelona   3313         0     1318
Brussels    2963      1318        0

基本R中的另一种简单方法是使用 XTABS 。 XTABS 的结果基本上只是一个带有精美类名称的矩阵，但是您可以使其看起来像常规矩阵，带有 class（x）= null; attr; attr; attr; attr; attr; attr; attr（x，“ call'call'' ）= null; dimNames（x）= unname（dimnames（x））：

> x=xtabs(value~name+numbers,dat1);x
            numbers
name                  1          2          3          4
  firstName   0.3407997 -0.7033403 -0.3795377 -0.7460474
  secondName -0.8981073 -0.3347941 -0.5013782 -0.1745357
> str(x)
 'xtabs' num [1:2, 1:4] 0.341 -0.898 -0.703 -0.335 -0.38 ...
 - attr(*, "dimnames")=List of 2
  ..$ name   : chr [1:2] "firstName" "secondName"
  ..$ numbers: chr [1:4] "1" "2" "3" "4"
 - attr(*, "call")= language xtabs(formula = value ~ name + numbers, data = dat1)
> class(x)
[1] "xtabs" "table"
> class(as.matrix(x)) # `as.matrix` has no effect because `x` is already a matrix
[1] "xtabs" "table"
> class(x)=NULL;class(x)
[1] "matrix" "array"
> attr(x,"call")=NULL;dimnames(x)=unname(dimnames(x))
> x # now it looks like a regular matrix
                    1          2          3          4
firstName   0.3407997 -0.7033403 -0.3795377 -0.7460474
secondName -0.8981073 -0.3347941 -0.5013782 -0.1745357
> str(x)
 num [1:2, 1:4] 0.341 -0.898 -0.703 -0.335 -0.38 ...
 - attr(*, "dimnames")=List of 2
  ..$ : chr [1:2] "firstName" "secondName"
  ..$ : chr [1:4] "1" "2" "3" "4"

正常 as.data.frame（x）转换 XTABS back的结果要长时间格式，但是您可以使用 class（x）= null ：这可以避免使用它：

> x=xtabs(value~name+numbers,dat1);as.data.frame(x)
        name numbers       Freq
1  firstName       1  0.3407997
2 secondName       1 -0.8981073
3  firstName       2 -0.7033403
4 secondName       2 -0.3347941
5  firstName       3 -0.3795377
6 secondName       3 -0.5013782
7  firstName       4 -0.7460474
8 secondName       4 -0.1745357
> class(x)=NULL;as.data.frame(x)
                    1          2          3          4
firstName   0.3407997 -0.7033403 -0.3795377 -0.7460474
secondName -0.8981073 -0.3347941 -0.5013782 -0.1745357

这将以宽阔的格式转换到长格式（ linrist 将dataframe转换为vector和<代码> C 将矩阵转换为向量）：

w2l=function(x)data.frame(V1=rownames(x)[row(x)],V2=colnames(x)[col(x)],V3=unname(c(unlist(x))))
