在 Django 模型的模板中显示键/值对

Question

对不起，如果问题本身令人困惑。我有一个模型，其中包含两个列表，用作下拉列表供用户选择。一切都很好，除了在查看数据时，当我希望它显示值时，它只会显示键。

models.py

class RestroomReview(models.Model):
MEN = 'M'
WOMEN = 'W'
UNISEX = 'U'
FAMILY = 'F'
RESTROOM_TYPE_CHOICES = [
('M', 'Men'),
('W', 'Women'),
('U', 'Unisex'),
('F', 'Family')
]
RATING_CHOICES = [
(1, 'Poor'),
(2, 'Average'),
(3, 'Good'),
(4, 'Very Good'),
(5, 'Excellent')
]
venue = models.ForeignKey(Venue, blank=False, on_delete=models.CASCADE)
user = models.ForeignKey('auth.User', blank=False, on_delete=models.CASCADE)
public = models.BooleanField(blank=False)
rest_type = models.CharField(
max_length=1, 
choices=RESTROOM_TYPE_CHOICES, 
default=MEN
)
baby = models.BooleanField('Changing Table')
needle = models.BooleanField('Sharps Container')
handicap = models.BooleanField('Handicap Accessible')
rating = models.IntegerField(choices=RATING_CHOICES, default=1)
title = models.CharField(max_length=200, blank=False)
comment = models.TextField(max_length=1000, blank=False)
posted_date = models.DateTimeField(blank=False)

review_detail.html

{% extends 'restroom_rater/base.html' %}
{% block content %}
<div>
<h3>{{ review.venue.name }}</h3>
<p>Title: {{ review.title}}</p>
<p>by {{ review.user }}</p>
<p>Public: {{ review.public }}</p>
<p>Type: {{ review.rest_type }}</p>
<p>Changing Table: {{ review.baby }}</p>
<p>Sharps Container: {{ review.needle }}</p>
<p>Handicap Accessible: {{ review.handicap }}</p>
<p>Rating: {{ review.rating }}</p>
<p>Comment: {{ review.comment }}</p>
<p>Date Posted: {{ review.posted_date }}</p>
</div>
{% endblock %}

所以在我的review_detail模板中，我希望它说"男人"、"女人"、"男女皆宜"或"家庭"，但它显示"M"、"W"、"U"、"F"。评级也是如此。我希望它显示"差"、"好"等，但它给出了数字评级。

我想你正在寻找

{{ review.get_rest_type_display }}

一般来说，get_FIELDNAME_display()会给你显示值。
