저는 스택 오버플로에서 많은 질문에서 이 문제를 발견했지만 운이 없었습니다.제가 무엇을 잘못하고 있는지 이해할 수 있도록 도와주세요.

구성 요소:

ngOnInit() {
    this.companyCreatForm = this._formBuilder.group({
      name: [null, [Validators.required, Validators.minLength(5)]],
      about: [null, [Validators.required]],
      businessType: [null, [Validators.required]],
      address: this._formBuilder.group({
        street: [],

지정해야 합니다.formGroupName중첩 컨트롤의 경우

<div class="panel panel-default" formGroupName="address"> <== add this
    <div class="panel-heading">Contact Info</div>

플런커 예제

HTML 코드에서

<form [formGroup]="userForm">
    <input type="text" class="form-control"  [value]="item.UserFirstName" formControlName="UserFirstName">
    <input type="text" class="form-control"  [value]="item.UserLastName" formControlName="UserLastName">
</form>

유형 스크립트 코드

export class UserprofileComponent implements OnInit {
    userForm: FormGroup;
    constructor(){ 
       this.userForm = new FormGroup({
          UserFirstName: new FormControl(),
          UserLastName: new FormControl()
       });
    }
}

이것은 완벽하게 작동하며 오류가 발생하지 않습니다.

저는 당신과 같은 오류를 얻었고 다음과 같이 ts 파일의 제어 이름을 폼 작성기에 선언함으로써 해결했습니다.

 this.myForm = this.formBuilder.group({
        id: [],
        pageName: ['', [Validators.required]],
        urlPage: ['', [Validators.required]],
        title: ['', [Validators.required]],
        description: ['', [Validators.required]],
        pageContent: ['', [Validators.required]],

저도 이 오류가 있었는데, 당신이 해결을 도와줬습니다.formGroup 또는 formGroupName이 올바른 대소문자로 작성되지 않은 경우 컨트롤의 이름을 찾을 수 없습니다.formGroup 또는 formGroupName의 대소문자를 수정하면 정상입니다.

질문의 양이 개체에 따라 달라지기 때문에 동적으로 양식을 생성하려고 했고 추가할 때 오류가 수정되었습니다.ngDefaultControl나에게mat-form-field.

    <form [formGroup]="questionsForm">
        <ng-container *ngFor="let question of questions">
            <mat-form-field [formControlName]="question.id" ngDefaultControl>

        <button mat-raised-button (click)="sendFeedback()">Submit all questions</button>

sendFeedback()에서 폼 그룹의 값을 선택하여 동적 폼에서 값을 가져옵니다.

  sendFeedbackAsAgent():void {
    if (this.questionsForm.valid) {
      console.log(this.questionsForm.value)
    }
  }

나에게는 컨트롤 이름의 경우가 달랐습니다.

html에서 그것은 계정이었습니다.ID그리고 그것은 계정이었습니다.Id둘 다 일치하도록 사건을 변경한 것이 제 사건을 해결했습니다.

formGroup을 formControlName과 일치하도록 수정합니다.

문제의 요점은 모든 DB 필드가 AutoMapperProfile과 동일한 필드를 사용하여 명시적으로 매핑되어야 한다는 것입니다.

여기에는 모델 속성과 이름이 같아야 하는 폼 필드도 포함됩니다.양식에서 오는 모든 모델의 항목은 데이터베이스 항목에 있는 항목과 동일한 항목이어야 합니다.

예를 들어, AutoMapper Profile이 모델에 대해 8개의 필드를 나열하는 경우 양식에는 8개의 필드가 있어야 합니다.그런 다음 해당 모델을 8개의 필드와 함께 데이터베이스에 저장합니다.

대부분은 처리해야 합니다...

formControlName="xxx"인 내 formBuilder.group의 컨트롤과 관련된 태그를 사용하여 이 오류를 해결했습니다.

.ts 파일:

        this.reportForm = this.formBuilder.group({
            dateFrom: this.dateFromFC,
            dateTo: this.dateToFC,
            user: this.userFC,
        });

.html 파일:

매트 양식 필드 입력 내부

 <input type="text" matInput formControlName="user" [matAutocomplete]="auto">

나를 위해서라도.[formGroup]" 류가발습니다했오생▁"다▁"▁popping니▁the▁up▁was"로 뜨는 중이었습니다.Cannot find control with name:''".
제가 추가했을 때 고쳐졌습니다.ngModel 값과함께대와 입력 formControlName="fileName"

  <form class="upload-form" [formGroup]="UploadForm">
  <div class="row">
    <div class="form-group col-sm-6">
      <label for="fileName">File Name</label>
      <!-- *** *** *** Adding [(ngModel)]="FileName" fixed the issue-->
      <input type="text" class="form-control" id="fileName" [(ngModel)]="FileName"
        placeholder="Enter file name" formControlName="fileName"> 
    </div>
    <div class="form-group col-sm-6">
      <label for="selectedType">File Type</label>
      <select class="form-control" formControlName="selectedType" id="selectedType" 
        (change)="TypeChanged(selectedType)" name="selectedType" disabled="true">
        <option>Type 1</option>
        <option>Type 2</option>
      </select>
    </div>
  </div>
  <div class="form-group">
    <label for="fileUploader">Select {{selectedType}} file</label>
    <input type="file" class="form-control-file" id="fileUploader" (change)="onFileSelected($event)">
  </div>
  <div class="w-80 text-right mt-3">
    <button class="btn btn-primary mb-2 search-button cancel-button" (click)="cancelUpload()">Cancel</button>
    <button class="btn btn-primary mb-2 search-button" (click)="uploadFrmwrFile()">Upload</button>
  </div>
 </form>

그리고 컨트롤러에서.

ngOnInit() {
this.UploadForm= new FormGroup({
  fileName: new FormControl({value: this.FileName}),
  selectedType: new FormControl({value: this.selectedType, disabled: true}, Validators.required),
  frmwareFile: new FormControl({value: ['']})
});
}
