要获取ManyToManyField类型的字段和其值，可以使用以下方法：

1. 使用values()方法获取ManyToManyField类型字段的值。
2. 使用prefetch_related()方法预取ManyToManyField类型字段的值。
3. 使用queryset.values_list()方法获取ManyToManyField类型字段的值。
4. 使用queryset.annotate()方法注释ManyToManyField类型字段的值。

下面是每种方法的代码示例：

1. 使用values()方法获取ManyToManyField类型字段的值：

# models.py
class Book(models.Model):
    title = models.CharField(max_length=100)
    authors = models.ManyToManyField(Author)

# views.py
books = Book.objects.all().values('title', 'authors__name')
for book in books:
    print(book['title'], book['authors__name'])

2. 使用prefetch_related()方法预取ManyToManyField类型字段的值：

# models.py
class Book(models.Model):
    title = models.CharField(max_length=100)
    authors = models.ManyToManyField(Author)

# views.py
books = Book.objects.all().prefetch_related('authors')
for book in books:
    print(book.title, [author.name for author in book.authors.all()])

3. 使用queryset.values_list()方法获取ManyToManyField类型字段的值：

# models.py
class Book(models.Model):
    title = models.CharField(max_length=100)
    authors = models.ManyToManyField(Author)

# views.py
books = Book.objects.values_list('title', 'authors__name')
for book in books:
    print(book[0], book[1])

4. 使用queryset.annotate()方法注释ManyToManyField类型字段的值：

# models.py
class Book(models.Model):
    title = models.CharField(max_length=100)
    authors = models.ManyToManyField(Author)

# views.py
books = Book.objects.annotate(author_names=Concat('authors__first_name', 'authors__last_name'))
for book in books:
    print(book.title, book.author_names)

以上方法中的Author是ManyToManyField字段的相关模型。根据实际情况，需要根据自己的模型和字段进行相应的调整。
