Question

我正在尝试将菜单与_actualWork分开。为什么以下内容不起作用？

app.blade.php：

views/layouts/app.blade.php

<body> @yield('menu') <div class="container"> @yield('content') </div> </body>：

views/layouts/menu.blade.php

Answer 1

您不必yield菜单部分，而是include。正如您从official documentation中所读到的：

Blade的@include指令允许您从另一个视图中包含Blade视图。父视图可用的所有变量都将对包含的视图可用：

<div>
  @include('shared.errors')

  <form>
  <!-- Form Contents -->
  </form>
</div>

因此，您的layouts/app.blade.php文件应如下所示：

<body>
  @include('layouts.menu')

  <div class="container">
    @yield('content')
  </div>
</body>

Answer 2

您的app.blade.php应该看起来像这样

查找：views / layouts / app.blade.php

@Entity
public class Building {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    private String name;
    private String description;
    @OneToMany(mappedBy = "building", fetch = FetchType.EAGER, cascade = CascadeType.ALL, orphanRemoval = true)
    private List<Photo> photos;
    @ManyToMany(cascade = CascadeType.ALL)
    @JoinTable(name = "category_building",
            joinColumns = {@JoinColumn(name = "building_id")},
            inverseJoinColumns = {@JoinColumn(name = "category_id")
            })
    private List<Category> categories;

    public Building() {
    }

    public Building(String name, String description) {
        this.name = name;
        this.description = description;
    }

    public Building(String name, String description, List<Photo> photos) {
        this.name = name;
        this.description = description;
        this.photos = photos;
    }

    public Building(String name, String description, List<Photo> photos, List<Category> categories) {
        this.name = name;
        this.description = description;
        this.photos = photos;
        this.categories = categories;
    }
}

@Entity
public class Photo {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    @ManyToOne(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
    @JoinColumn(name = "building_id")
    private Building building;
    @Column(name = "original_size")
    byte[] originalSize;
    @Column(name = "small_size")
    byte[] smallSize;
    @Column(name = "middle_size")
    byte[] middleSize;
    @Column(name = "large_size")
    byte[] largeSize;

    public Photo() {
    }

    public Photo(Building building, byte[] originalSize) {
        this.building = building;
        this.originalSize = originalSize;
    }

和您的menu.blade.php

查找：views / layouts / menu.blade.php

<body>
   @include('layouts.menu')
   <div class="container">
     @yield('content')
    </div>
</body>
