我已经复制了这个代码,似乎是各种工作的dockerfiles,这是我的:

我正在使用Angular2和FormGroup构建一个深层嵌套表单,目前我有一个表单,例如在父控制器中:

this.orderForm = this.fb.group({

customerSelectForm: this.fb.group({ // create nested formgroup to pass to child
        selectTypeahead: ['', 
                            Validators.required],
        })
})

然后在一个子组件中我有:

<div class="form-group" [formGroup]="customerSelectForm" *ngIf="customerSelectForm">
        <label for="oh-custaccount">Customer Account #</label>

    <input class="form-control" type="text" 
    formControlName="selectTypeahead"
    (focusout)=someFunction() />

    <p *ngIf="customerSelectForm.controls.selectTypeahead.errors?.required">
    Number required!</p>
</div>

现在这个子模板工作正常,如果文本框中没有输入,则在屏幕上呈现错误.然后我在父控制器中返回一个提交按钮:

<button type="submit" class=" btn btn-success" [disabled]="orderForm?.invalid">Submit</button>

同样,这可以按预期工作,并且仅在selectTypeahead输入中注册输入后才启用.

现在由于这个表单的大型特性,我希望在提交按钮旁边有一个显示,它列出了当前失败的所有表单元素.我确实试过渲染:

{{orderForm.errors}}

但即使我的表单无效,这仍然是"空",我如何列出orderFrom中当前未通过/匹配其相应验证规则的所有输入？

我已向Google Directions API提出请求,并收到了以下JSON说明:

但是,唉,这不起作用,任何人都有任何想法为什么？这应该是一个相当基本的练习.因为它只是使用谷歌自己的API.

我有以下行动:

export const ActionTypes = {
  CREATE_OH:                  type('[ORDERHEAD] Create Orderhead'),
  MODIFY_SELECTED_OH:    type('[ORDERHEAD] Select Orderhead'),     
};

export class CreateOHAction implements Action {
  type = ActionTypes.CREATE_OH

  constructor(public payload: OrderHead[]) { }
}

export type Actions
  =   CreateOHAction
  |   SelectOHAction;

使用以下基础减速器设置

export interface State {
  orderids: string[];
  entities: { [orderID: string]: OrderHead };
  selectedOhID: string | null;
};

// Set initial state to empty
const initialState: State = {
  orderids : [],
  entities: {},
  selectedOhID: null,

};
export function OHreducer(state = initialState, action: …

我正在尝试搜索一些模型，因此我希望显示所有父对象的返回结果，其中父对象名称为“foo”或子对象名称为“foo”。

我有疑问：

parents = Session.query(Parent).\
            join(Child_s3).\
            filter(Parent.name.ilike("%foo%")).\
            filter(Child_s3.name.ilike("%foo%")).\
            order_by(asc(Product.name))

以及型号：

class Parent(BaseSO):
    __tablename__ = 'parents'
    id = Column(Integer, primary_key=True)
    name = Column(Unicode(100), nullable=False, unique=True)
    colours = relationship('Child_s3', secondary=Parent_images, backref='Parentc')

class Child_s3(BaseSO):
    __tablename__ = 'children'
    id = Column(Integer, primary_key=True)
    name = Column(Unicode)

Parent_images = Table(
    'Parent_images', BaseSO.metadata,
    Column('parent_id', Integer, ForeignKey('parents.id')),
    Column('child_id', Integer, ForeignKey('children.id'))
)

我的查询显示名称为“foo”的父对象，但不显示任何父对象，该对象也有名为“foo”的子对象，任何人都可以帮助构建此查询以在两个表中搜索相应的父对象吗？

在文档和源代码中，我看到很多对圆角矩形的引用，但是，我似乎无法绘制一个。

我正在绘制一个普通的矩形：

canvas.rect(15, 625, 250, 125, fill=0)

我要向拐角处传递哪些论据？

所以我的代码编译时没有错误，但是在使用时出现错误......

我的表单组件：

export class OrderHeaderComponent implements OnInit {
    orderForm: FormGroup;
    orderLines: FormArray;

    ngOnInit() {
        // build the form model
        this.orderLines = this.fb.array([])
        this.orderForm = this.fb.group({

            orderHeadForm: this.fb.group({ // create nested formgroup to pass to child
                selectTypeahead: ['', 
                                    Validators.required],
                ohReference: ['', 
                                    Validators.required],
                }),

            orderLines: this.orderLines,

        })

    }

    someFunction(){
        this.orderLines.push(this.fb.group({
                    ['newInputName']: ['', 
                                    Validators.required],
                    }));
    }
}

现在这是一个父组件，它将表单传递给各个子组件（这可以减去我当前正在处理的 formArray 部分）。每个孩子看起来像这样：parent_template：

<form [formGroup]="orderForm" (ngSubmit)="orderFormSubmit()">
    <childTemplate [orderHeadForm]="orderForm.controls.orderHeadForm">
    </childTemplatet>
</form>

子模板：

<div class="form-group" [formGroup]="orderHeadForm">
        <label for="oh-custaccount">Customer Account #</label>

    <input class="form-control" type="text" 
    formControlName="selectTypeahead"
    (focusout)=lookupCustomerAccountReactive() />

    <p *ngIf="orderHeadForm.controls.selectTypeahead.errors?.required" …

所以我已经多次阅读过这篇文章,但是现在定义的设置和示例与商店示例应用程序中显示的方法不同.

我已经编写了大量基于示例应用程序的商店代码,因此如果我们继续使用示例应用程序在此帖子中进行参考:

书籍减速机:

export interface State {
  ids: string[];
  entities: { [id: string]: Book };
  selectedBookId: string | null;
};

const initialState: State = {
  ids: [],
  entities: {},
  selectedBookId: null,
};

export function reducer(state = initialState, action: book.Actions | collection.Actions): State {
  switch (action.type) {
    case book.ActionTypes.SEARCH_COMPLETE:
    case collection.ActionTypes.LOAD_SUCCESS: {
      const books = action.payload;
      const newBooks = books.filter(book => !state.entities[book.id]);

      const newBookIds = newBooks.map(book => book.id);
      const newBookEntities = newBooks.reduce((entities: { [id: string]: Book }, …

我使用了

AWSSecurityTokenServiceClient sts_client = new AWSSecurityTokenServiceClient(), 

并且自动设置了默认区域（全局）。但是此构造函数已弃用，建议使用：

AWSSecurityTokenServiceClientBuilder.

我也希望它使用默认区域。我写：

AWSSecurityTokenService stsClient = AWSSecurityTokenServiceClientBuilder.standard().withCredentials(new AWSStaticCredentialsProvider(awsCredentials)).build();

但我有一个例外：

com.amazonaws.SdkClientException: Unable to find a region via the region provider chain. Must provide an explicit region in the builder or setup environment to supply a region.

我是棱角材料库的新手（通常是材料设计规范），我已经使用引导程序多年了，所以不确定我是否正确实现了mat-grid-list，但是我有以下几点：

<mat-card>
<mat-grid-list cols="2">
    <mat-grid-tile>
        <mat-grid-tile-header>Clocked In</mat-grid-tile-header>
        <mat-list>
            <mat-list-item> 
                <button  mat-raised-button color="warn">
                        {{user.firstName}} {{user.lastName}}
                </button>
            </mat-list-item>
        </mat-list>
    </mat-grid-tile>
    <mat-grid-tile>
        <mat-grid-tile-header>Clocked Out</mat-grid-tile-header>
        <mat-list>
            <mat-list-item> 
                <button mat-raised-button color="accent">
                    {{user.firstName}} {{user.lastName}}
                </button>
            </mat-list-item>
        </mat-list>
    </mat-grid-tile>
</mat-grid-list>

这基于有角度的材料示例，我在其中包括了一个有效的stackblitz示例：https ://stackblitz.com/edit/angular-cccnjp ? file = app%2Fsidenav-sensitive-example.html

如您所见，按钮已呈现在mat-grid-tile-header内部，并且mat-card尚未扩展以容纳所提供的内容（正如我所期望的那样）

编辑：所以，我确实尝试在mat-grid-list上使用rowHeight =“ fit”属性，但这不会呈现任何内容，我希望这会根据内容来扩大mat-grid-list的高度，但是这是行不通的。

更新： 丑陋的工作解决方案

所以我设法用一些（非常丑陋的）CSS实现了这一点...
