        let id = params['id'];
        this.moviesService.getComments(id)
          .subscribe(comments => {
            console.log(comments);
            this.comments = comments;
          });

          </select>
        </div>
        <div class="input-group mb-3 form-element_hotel">
          <select class="custom-select" id="inputGroupSelect01" #hotelName>
            <option selected *ngFor="let hotel of hotels" [ngValue]="hotel.name">{{hotel.name}}</option>

          </select>

            [disabled]="!validEmail">Book</button>
        </div>
      </div>
    </form>
  </div>

when I submit the data I get the following error:

BookingComponent.html:59 ERROR Error: Cannot find control with name: 'date'

what is wrong with my code?

Answer 1

in your createForm() function you didn't add the date FormControl

createForm() {
  this.angForm = this.fb.group({
    email: new FormControl('', [Validators.required, Validators.email]),
    date: new FormControl('') // this line missing in your code
  });
}

you shouldn't use both ngModel (template driven forms) and formControlName (reactive forms) in the same input.
