How do I use route model binding in a controller?

How do I use route model binding in a controller?

Using routing model binding in Laravel automatically parses model instances to avoid manual queries. Implicit binding automatically obtains the model by matching the route parameter name and type prompt; explicit binding allows custom parsing logic, such as using slug instead of id; directly type prompting the model in the controller method can use binding instances; additional constraints such as ownership verification can be handled through middleware or custom binding logic.

How do I define a constructor in a controller?

How do I define a constructor in a controller?

The key to defining a controller constructor in Angular is to understand its initialization and dependency injection. The constructor is used to initialize class instances and inject dependencies, such as service or configuration parameters. Common practices include: 1. Use the constructor keyword declaration to automatically create attributes; 2. Injecting services to implement data calls, ensuring that corresponding services are provided in the module; 3. Supporting multiple parameters to be arranged in logical order; 4. Avoid executing HTTP requests or complex logic in the constructor, and life cycle hooks should be used to handle it. The constructor should be kept concise to facilitate maintenance and testing.
