Python ManyToManyField关系检索不到数据

我有一个这样的结构： 1.作者 2.书 3.作者类型 4.AuthorBookType

一本书可以有多个作者，书中可以有“作者”、“合著者”、“部分”、“助手”等功能：

我的数据库应如下所示：

AUTHOR:
__________________________
| ID | NAME              |
|========================|
| 1  | Jhon Doe.         |
| 2  | Charles Albert    |
| 3  | Matt Greg         |
| 4  | Anne Engel        |
--------------------------

BOOK:
__________________________
| ID | NAME              |
|========================|
| 1  | Paradise City     |
| 2  | Profaned Apple    |
--------------------------

AUTHOR_TYPE:
__________________________
| ID | DESCRIPTION       |
|========================|
| 1  | Author            |
| 2  | Co-Author         |
--------------------------

AUTHOR_BOOK_TYPE:
_____________________________________________
| ID | AUTHOR_ID | BOOK_ID | AUTHOR_TYPE_ID |
|===========================================|
| 1  | 1         | 1       | 1              |
| 2  | 2         | 1       | 2              |
| 3  | 3         | 1       | 2              |
| 4  | 3         | 2       | 1              |
| 5  | 4         | 2       | 2              |
---------------------------------------------

在我的views.py上，我做到了：

class AuthorsListView(ListView)
    model = Author
    context_object_name = 'authors'
    template_name = 'core/authors_list.html'

然后在我的模板上：

{% for author in authors %}
    {{ author.name }}<br>
    {{ author.books }}
{% endfor %}

{作者中的作者%}
{{author.name}}

{{author.books}}
{%endfor%}

回报是：

<author name>
<core.Books.None>

---

也许是更清晰的解决方案

from .models import Author
class AuthorsListView(ListView)
    model = Author
    context_object_name = 'authors'
    template_name = 'core/authors_list.html'
    def get_queryset(self):
        return Author.objects.all()

这里Django版本之间的语法没有区别；您找到的任何文档都仍然有效

您需要迭代多对多关系：

{% for author in authors %}
    {{ author.name }}<br>
    {% for book in author.books.all %}{{ book.title }}{% endfor %}
{% endfor %}

{作者中的作者%}
{{author.name}}

{%for author.books.all%}{{book.title}{%endfor%}
{%endfor%}

{% for author in authors %}
    {{ author.name }}<br>
    {% for book in author.books.all %}{{ book.title }}{% endfor %}
{% endfor %}
