如何在Django中使用选项-如何显示特定内容？
提问于 2018-07-30 00:56:54
我尝试在Django中创建一个图书数据库。我还有一件事要做。所以我有一个有选择的模型：
#model Book课本(models.Model)：
#book types and placed
BIOGRAPHY = 1
FANTASY = 2
HISTORICAL = 3
HORROR = 4
CLASSIC = 5
YOUTH_LITHERATURE = 6
NON_FICTION = 7
MODERN_LITERATURE = 8
POETRY = 9
ADVENTURE = 10
ESSAYS = 11
ROMANCE = 12
SATIRE = 13
THRILLER = 14
DRAMA = 15
NONE = 0
B00K_CHOICES = (
(BIOGRAPHY,'Biography'),
(FANTASY, 'Fantasy/Sci-Fi'),
(HISTORICAL, 'Historical'),
(HORROR, 'Horror'),
(CLASSIC, 'Classic'),
(YOUTH_LITHERATURE, 'Youth Litherature'),
(NON_FICTION, 'Non-Fiction'),
(MODERN_LITERATURE, 'Modern Literature'),
(POETRY, 'Poetry'),
(ADVENTURE, 'Adventure'),
(ESSAYS, 'Essays'),
(ROMANCE, 'Romance'),
(SATIRE, 'Satire'),
(THRILLER, 'Thriller'),
(DRAMA, 'Drama'),
(NONE, 'No Information'),
)
book_image = models.ImageField(upload_to='book_image', blank=True, null=True)
book_name = models.CharField(max_length=255, unique=True)
book_author = models.ForeignKey(Author, on_delete=models.CASCADE)
book_types = models.IntegerField(choices=B00K_CHOICES, default= NONE)
book_description = models.TextField(null=True, blank=True)
book_pages = models.PositiveIntegerField(null=True, blank=True)
book_published = models.DateField(null=True, blank=True)
book_ratings = GenericRelation(Rating, related_query_name='book', default=NONE)
def __str__(self):
return '{}'.format(self.book_name)然后，我创建了一个简单的视图，其中包含display this choices：
def book_types_list(request):
book = Book.objects.all()
context = {'book': book, 'book_types': Book.B00K_CHOICES}
return render(request, 'plibrary_core/book_types_list.html', context)我还创建了一个包含此选项列表的html模板：
{% extends 'base.html' %}
{% load static %}
{% block custom %}
<link rel='stylesheet' type="text/css" href="{% static 'css/background_color_styles.css' %}">
{% endblock %}
{% block title %}
<title>Book Types List | Private Library</title>
{% endblock %}
{% block content %}
<div class="container">
<div class="col">
<div id="background-color-content">
<h3>Book Types</h3>
<hr>
{% for book_type in book_types %}
<ul>
<h6><a href="#">{{ book_type }}</a></h6>
</ul>
{% endfor %}
</div>
</div>
</div>
{% endblock %}在这个时刻，我需要类似这样的东西-用户点击图书类型(例如Horror)，然后他会看到另一个模板，其中包含仅包含此类型的所有图书。我试着这样做，但它不起作用。我不知道该怎么解决它。有人知道我需要做什么吗？；X

有了这个元素，您就可以在屏幕上呈现一个select元素，它将使用您在select中提供的选项，而不是图书类型的for循环
