Question

我有三个桌子，一个是mandal，村庄和财产，在属性表中我将mandal和村庄与外键联系起来，现在当我选择mandal时，只有那个特定的村庄结果必须以django的财产形式显示管理员。我还将mandal与村庄联系起来。

#models.py
from django.db import models
from django.utils import timezone

class Mandal(models.Model):
    id = models.AutoField(
        primary_key=True,
        db_column="Mandal_id",
        verbose_name="Mandal Id",
    )
    name = models.CharField(
        max_length=200,
        db_column="Mandal_Name",
        verbose_name="Mandal Name",
        null=False,
        blank=False,
        help_text="Enter Mandal names only",
        default=None,
    )
    class Meta:
        db_table = "Mandal"
        verbose_name_plural = "Mandal"

    def __str__(self):
        return self.name

class Village(models.Model):
    id = models.AutoField(
        primary_key=True,
        db_column="Village_id",
        verbose_name="Village Id",
    )
    name = models.CharField(
        max_length=200,
        db_column="Village_Name",
        verbose_name="Village Name",
        null=False,
        blank=False,
        help_text="Enter village names only",
        default=None,
    )
    mandal_id = models.ForeignKey(
        Mandal,
        db_column="Mandal_id",
        verbose_name="Mandal Name",
    )

    class Meta:
        db_table = "Village"
        verbose_name_plural="Village"

    def __str__(self):
        return self.name

class Properties(models.Model):
    id = models.BigAutoField(
        primary_key=True,
        db_column="Property_id",
        verbose_name="Property Id"
    )
    created_on = models.DateField(
        auto_now=False,
        auto_now_add=False,
        default=timezone.now(),
    )
    area = models.BigIntegerField(
        default=0,
        db_column="Property_Area",
        verbose_name="Property Area",
        help_text="Please enter area in square feet",
        validators=[],
    )
    mandal_location = models.ForeignKey(
        Mandal,
        db_column="Mandal_id",
        verbose_name="Mandal Name",
        default=None,
    )
    village_location = models.ForeignKey(
        Village,
        db_column="Village_id",
        verbose_name="Village Name",
        default=None,
    )

    description = models.TextField(
        default=None,
        db_column="Property_description",
        verbose_name="Property Description",
    )
    features = models.CharField(
        default=None,
        db_column="Property_Features",
        verbose_name="Property Features",
        null=True,
        blank=True,
        help_text="Add Property Fetures",
        max_length=1000,
    )
    additional_features = models.CharField(
        default=None,
        db_column="Property_Additional_Features",
        verbose_name="Additional Features",
        null=True,
        blank=True,
        help_text="Add Property Fetures",
        max_length=1000
    )

    class Meta:
        db_table = "Properties"
        verbose_name_plural = "Property"

    def __str__(self):
        return "Pr-{i}".format(i=self.id)

#admin.py
from django.contrib import admin
from whiteindia.models import Mandal,Village,Properties

class MandalAdmin(admin.ModelAdmin):
    list_display = ['id','name']

    class Meta:
        model = Mandal

class VillageAdmin(admin.ModelAdmin):
    list_display = ['id','name','mandal_id']
    list_filter = ['mandal_id']

    class Meta:
        model = Village

class PropertiesAdmin(admin.ModelAdmin):
    list_display = ['id', 'area','village_location','mandal_location']

    class Meta:
        model = Properties

admin.site.register(Mandal,MandalAdmin)
admin.site.register(Village,VillageAdmin)
admin.site.register(Properties,PropertiesAdmin)

那么当我们在浏览器窗口中输入admin / property时，如何让村庄列表到admin中属性的特定mandal

Answer 1

我不太确定你想要如何显示你的数据，但是你看过inlineModelAdmin。

管理界面能够在与父模型相同的页面上编辑模型。这些被称为内联。

我使用它来编辑管理页面中的记录，该记录还显示另一个也可以编辑的表中的子记录。在您的情况下，您可以使用它来单击属性进行编辑，并且在属性下面的编辑页面上，它可以显示与其相关的所有Mandals或村庄。如果要链接3个表，可以使用“通过”选项进行链接。查看以下文档：
