Django QuerySet 显示不正确的字符串

Question

在我的视图中渲染 ManyToMany 字段时遇到问题。

#模型：

from django.db import models


class Ingredient(models.Model):
    content = models.CharField(max_length=300, default='')

    def __str__(self):
        return self.content


class Drink(models.Model):
    ingredient = models.ManyToManyField(Ingredient)
    title = models.CharField(max_length=300)
    description = models.TextField(max_length=500)

    def __str__(self):
        return self.title

#查看：

from django.shortcuts import render
from .models import Drink, Ingredient


def index(request):
    drinks = Drink.objects.all()
    context = {'drinks': drinks}
    return render(request, 'drinks/index.html', context)

#模板：

{% for i in drinks %}
    <h3>{{ i.title }}</h3>
    <p><b>Description:</b> <br>{{ i.description }}</p>
    <p>{{ i.ingredient.all }}</p>
{% endfor %}

这是我的网站：

Screw driver

Description: 
Good drink made of pure vodka and California cultured oranges.

<QuerySet [<Ingredient: Vodka>, <Ingredient: Orange juice>]>

我找不到任何合适的方法来过滤或格式化最后一个字符串。 有人有想法吗？

Answer 1

您也需要对成分进行迭代。

{% for i in drinks %}
    <h3>{{ i.title }}</h3>
    <p><b>Description:</b> <br>{{ i.description }}</p>
    {% for j in i.ingredient.all %}
       <p>{{ j }}</p>
{% endfor %}
