refactor(forms): deprecate ngModel usage on same field as formControl (#22633) Support for using the `ngModel` input property and `ngModelChange` event with reactive form directives has been deprecated in Angular v6 and will be removed in Angular v7. Now deprecated: ```html <input [formControl]="control" [(ngModel)]="value"> ``` ```ts this.value = 'some value'; ``` This has been deprecated for a few reasons. First, developers have found this pattern confusing. It seems like the actual `ngModel` directive is being used, but in fact it's an input/output property named `ngModel` on the reactive form directive that simply approximates (some of) its behavior. Specifically, it allows getting/setting the value and intercepting value events. However, some of `ngModel`'s other features - like delaying updates with`ngModelOptions` or exporting the directive - simply don't work, which has understandably caused some confusion. In addition, this pattern mixes template-driven and reactive forms strategies, which we generally don't recommend because it doesn't take advantage of the full benefits of either strategy. Setting the value in the template violates the template-agnostic principles behind reactive forms, whereas adding a FormControl/FormGroup layer in the class removes the convenience of defining forms in the template. To update your code before v7, you'll want to decide whether to stick with reactive form directives (and get/set values using reactive forms patterns) or switch over to template-driven directives. After (choice 1 - use reactive forms): ```html <input [formControl]="control"> ``` ```ts this.control.setValue('some value'); ``` After (choice 2 - use template-driven forms): ```html <input [(ngModel)]="value"> ``` ```ts this.value = 'some value'; ``` You can also choose to silence this warning by providing a config for `ReactiveFormsModule` at import time: ```ts imports: [ ReactiveFormsModule.withConfig({warnOnNgModelWithFormControl: 'never'}); ] ``` Alternatively, you can choose to surface a separate warning for each instance of this pattern with a config value of `"always"`. This may help to track down where in the code the pattern is being used as the code is being updated. Note: `warnOnNgModelWithFormControl` is set up as deprecated so that it can be removed in v7 when it is no longer needed. This will not display properly in API docs yet because dgeni doesn't yet support deprecating properties in object literals, but we have an open issue to resolve the discrepancy here: https://github.com/angular/angular/issues/22640.

refactor(forms): deprecate ngModel usage on same field as formControl (#22633) Support for using the `ngModel` input property and `ngModelChange` event with reactive form directives has been deprecated in Angular v6 and will be removed in Angular v7. Now deprecated: ```html <input [formControl]="control" [(ngModel)]="value"> ``` ```ts this.value = 'some value'; ``` This has been deprecated for a few reasons. First, developers have found this pattern confusing. It seems like the actual `ngModel` directive is being used, but in fact it's an input/output property named `ngModel` on the reactive form directive that simply approximates (some of) its behavior. Specifically, it allows getting/setting the value and intercepting value events. However, some of `ngModel`'s other features - like delaying updates with`ngModelOptions` or exporting the directive - simply don't work, which has understandably caused some confusion. In addition, this pattern mixes template-driven and reactive forms strategies, which we generally don't recommend because it doesn't take advantage of the full benefits of either strategy. Setting the value in the template violates the template-agnostic principles behind reactive forms, whereas adding a FormControl/FormGroup layer in the class removes the convenience of defining forms in the template. To update your code before v7, you'll want to decide whether to stick with reactive form directives (and get/set values using reactive forms patterns) or switch over to template-driven directives. After (choice 1 - use reactive forms): ```html <input [formControl]="control"> ``` ```ts this.control.setValue('some value'); ``` After (choice 2 - use template-driven forms): ```html <input [(ngModel)]="value"> ``` ```ts this.value = 'some value'; ``` You can also choose to silence this warning by providing a config for `ReactiveFormsModule` at import time: ```ts imports: [ ReactiveFormsModule.withConfig({warnOnNgModelWithFormControl: 'never'}); ] ``` Alternatively, you can choose to surface a separate warning for each instance of this pattern with a config value of `"always"`. This may help to track down where in the code the pattern is being used as the code is being updated. Note: `warnOnNgModelWithFormControl` is set up as deprecated so that it can be removed in v7 when it is no longer needed. This will not display properly in API docs yet because dgeni doesn't yet support deprecating properties in object literals, but we have an open issue to resolve the discrepancy here: https://github.com/angular/angular/issues/22640.

refactor(forms): deprecate ngModel usage on same field as formControl (#22633) Support for using the `ngModel` input property and `ngModelChange` event with reactive form directives has been deprecated in Angular v6 and will be removed in Angular v7. Now deprecated: ```html <input [formControl]="control" [(ngModel)]="value"> ``` ```ts this.value = 'some value'; ``` This has been deprecated for a few reasons. First, developers have found this pattern confusing. It seems like the actual `ngModel` directive is being used, but in fact it's an input/output property named `ngModel` on the reactive form directive that simply approximates (some of) its behavior. Specifically, it allows getting/setting the value and intercepting value events. However, some of `ngModel`'s other features - like delaying updates with`ngModelOptions` or exporting the directive - simply don't work, which has understandably caused some confusion. In addition, this pattern mixes template-driven and reactive forms strategies, which we generally don't recommend because it doesn't take advantage of the full benefits of either strategy. Setting the value in the template violates the template-agnostic principles behind reactive forms, whereas adding a FormControl/FormGroup layer in the class removes the convenience of defining forms in the template. To update your code before v7, you'll want to decide whether to stick with reactive form directives (and get/set values using reactive forms patterns) or switch over to template-driven directives. After (choice 1 - use reactive forms): ```html <input [formControl]="control"> ``` ```ts this.control.setValue('some value'); ``` After (choice 2 - use template-driven forms): ```html <input [(ngModel)]="value"> ``` ```ts this.value = 'some value'; ``` You can also choose to silence this warning by providing a config for `ReactiveFormsModule` at import time: ```ts imports: [ ReactiveFormsModule.withConfig({warnOnNgModelWithFormControl: 'never'}); ] ``` Alternatively, you can choose to surface a separate warning for each instance of this pattern with a config value of `"always"`. This may help to track down where in the code the pattern is being used as the code is being updated. Note: `warnOnNgModelWithFormControl` is set up as deprecated so that it can be removed in v7 when it is no longer needed. This will not display properly in API docs yet because dgeni doesn't yet support deprecating properties in object literals, but we have an open issue to resolve the discrepancy here: https://github.com/angular/angular/issues/22640.
