python - 如何在 Django 管理更改表单中显示相关表的内容？

Question

我是编程、Python 和 Django 的新手，因此感谢您的耐心等待。我一直在 Django 中编写一个用于存储 cooking 食谱的练习应用程序。我有两个模型:

class Recipe(models.Model):
    recipe_name = models.CharField(max_length=30)
    recipe_instructions = models.TextField()
    recipe_whyitworks = models.TextField(verbose_name="Why It Works")
    recipe_date = models.DateField()
    def __str__(self):
       return self.recipe_name
    def was_published_recently(self):
       return self.recipe_date >= timezone.now() -datetime.timedelta(days=5)

class Ingredient(models.Model):
    recipe = models.ForeignKey(Recipe, on_delete=models.CASCADE)
    ingredient_name = models.CharField(max_length=30)
    ingredient_qty = models.DecimalField(verbose_name='Quantity', max_digits=3, decimal_places=2)
    ingredient_uom = models.CharField(verbose_name='Unit of Measure', max_length=15)
    def __str__(self):
        return self.ingredient_name

我将管理员设置为能够编辑任一表:

from django.contrib import admin

# Register your models here.
from .models import Recipe, Ingredient

admin.site.register(Recipe)
admin.site.register(Ingredient)

我想要做的是，当我单击“成分”时，我希望它显示之前添加到配方中的所有成分，以及表格中每种成分的数量和计量单位以及字段这允许我添加一个新的。预先感谢您的帮助!

您可以像这样添加内联:

admin.py

from django.contrib import admin

class IngredientInline(admin.TabularInline):
    model = Ingredient

class RecipeAdmin(admin.ModelAdmin):
    inlines = [
        IngredientInline,
    ]

admin.site.register(Recipe, RecipeAdmin)
admin.site.register(Ingredient)
