How to control automatic model loading in laravel controller method?

Question

Laravel

Using the artisan command, I created a controller bound to the Announcement model. In the same place I found a very interesting code of the following type.

public function show(Announcement $announcement)
    {
    	/****/
    }

That is, laravel itself injects a ready-made model, knowing by url with what id it is necessary to request from the database.
And everything would be fine, but I did not find information about this in the documentation. I thought that I would find the answer in the section about service containers, but the search was unsuccessful. The bottom line is that I need to load the relation when loading the model in this way, but I don’t know where to go with this. Of course, you can use load instead of with, but I would like to organize this in one request to the database, and not write extra code in the method.

In the context of a single model, rather than a collection, load works exactly the same as with - it makes a second query to the relationship table.
So you can even not call load, but simply use a relation - Eloquent will automatically load everything. Load is needed here only if you need to control the loading of the relation: specify an additional condition or additional links.
