Pythonの自作パッケージで定数を使いたい |

Constクラスのinit内で定数を宣言しても良いとは思いますが、その場合は子クラスのinitでsuperinitを忘れないようにしましょう。 |

Forms in Angular |
https://dev.to/ahmeddoosama/forms-in-angular-3m11
|
Forms in Angular gt Angular provides to different approaches to handling user input through forms reactive forms amp template driven forms Reactive forms and template driven forms each of them has different advantages when mange form data Reactive forms ⇒ Provide direct explicit access to underlying forms object model they re more scalable reusable and testable If you work in large project and the form are a key part of your application use reactive forms Template driven forms ⇒ depend on directive in the template to create and manipulate the underlying object model If you have very basic form requirements and logic template driven form could be a good fit This table show the key difference between reactive and template driven forms Scalability If the forms is essential part of your project scalability is very important Reactive forms ⇒ It s are more scalable than template driven forms They provide direct access to the underlying from API and use synchronous data flow between the view and data model which makes creating large scale forms easier Template driven forms ⇒ It s are less scalable than reactive forms They abstract away the underlying from API and use async data flow between the view and the data model Setup and data flow in reactive forms In reactive forms you define the form model directly in the component class The formControl directive links the explicitly created formControl instance to a specific form element in the view gt In this figure you will see the formcontrol directive links directly to form element in the view gt Data Flow In reactive forms the updates from the view to the model and from the model to the view are synchronous and do not depend on how the UI is rendered gt Data flow form the view to the modelIn this figure show how data flow changed from the view to model through the following steps A value is typed by the user into the input element In this example the value is blue The form input element emits an “input event with the latest value The control value accessor listening for events on the form input element immediately relays the new value to the formControl instance The formControl instance emits the new value through the valueChanges observable The new value is received by any subscribers to the valueChanges observable gt Data flow form the model to the viewIn this figure show how data flow changed from the model to view through the following steps The user calls the favoriteColorControl setValue method which updates the FormControl value The FormControl instance emits the new value through the valueChanges observable Any subscribers to the valueChanges observable receive the new value The control value accessor on the form input element updates the element with the new value Setup and data flow in template driven forms In template driven forms the form model is implicit The directive NgModel creates and manages a FormControl instance for a given form element gt In a template driven form the source of truth is the template You do not have direct programmatic access to the FormControl instance Data Flow In template driven forms each form element is linked to a directive that manages the form model internally gt Data Flow from View to ModelIn this figure show how data flow changed from the view to model through the following steps A value Blue is typed by the user into the input element An “input event having the new value is emitted by the input element The setValue method on the FormControl instance is triggered by the control value accessor attached to the input The FormControl instance emits the new value through the valueChanges observable Any subscribers to the valueChanges observable receive the new value The NgModel viewToModelUpdate method is also called by the control value accessor It emits an ngModelChange event For the defined property the component template uses two way data binding The value emitted by the ngModelChange event is used to update the defined property in the component gt Data Flow from Model to ViewIn this figure show how data flow changed from the model to view through the following steps The defined property is updated to a new value in the component The Change detection then starts The ngOnChanges lifecycle hook is called on the NgModel directive instance during the change detection The reason being that the value of one of its inputs has changed An async task is queued by the ngOnChanges method to set the value for the internal FormControl instance The Change detection is now completed To set the FormControl instance value the required task is executed The latest value is emitted by the FormControl instance through the valueChanges observable Any subscribers to the valueChanges observable receive the new value The control value accessor updates the form input element in the view with the latest value |
