Django Admin Cookbook介绍

Django Admin Cookbook 是一本关于Django Admin 模块的书

它面向Django的对DjangoAdmin有一些使用经验但是想要扩大对DjangoAdmin的认知甚至想要精通DjangoAdmin的中级Django开发者.

它采用问答的形式来讨论关于你可能会使用DjangoAdmin完成的常见任务。

所有章节均基于一组通用模型：

App entities

  1. class Category(models.Model):
  2.     name = models.CharField(max_length=100)
  4.     class Meta:
  5.         verbose_name_plural = "Categories"
  7.     def __str__(self):
  8.         return self.name
  11. class Origin(models.Model):
  12.     name = models.CharField(max_length=100)
  14.     def __str__(self):
  15.         return self.name
  18. class Entity(models.Model):
  19.     GENDER_MALE = "Male"
  20.     GENDER_FEMALE = "Female"
  21.     GENDER_OTHERS = "Others/Unknown"
  23.     name = models.CharField(max_length=100)
  24.     alternative_name = models.CharField(
  25.         max_length=100, null=True, blank=True
  26.     )
  29.     category = models.ForeignKey(Category, on_delete=models.CASCADE)
  30.     origin = models.ForeignKey(Origin, on_delete=models.CASCADE)
  31.     gender = models.CharField(
  32.         max_length=100,
  33.         choices=(
  34.             (GENDER_MALE, GENDER_MALE),
  35.             (GENDER_FEMALE, GENDER_FEMALE),
  36.             (GENDER_OTHERS, GENDER_OTHERS),
  37.         )
  38.     )
  39.     description = models.TextField()
  41.     def __str__(self):
  42.         return self.name
  44.     class Meta:
  45.         abstract = True
  48. class Hero(Entity):
  50.     class Meta:
  51.         verbose_name_plural = "Heroes"
  53.     is_immortal = models.BooleanField(default=True)
  55.     benevolence_factor = models.PositiveSmallIntegerField(
  56.         help_text="How benevolent this hero is?"
  57.     )
  58.     arbitrariness_factor = models.PositiveSmallIntegerField(
  59.         help_text="How arbitrary this hero is?"
  60.     )
  61.     # relationships
  62.     father = models.ForeignKey(
  63.         "self", related_name="+", null=True, blank=True, on_delete=models.SET_NULL
  64.     )
  65.     mother = models.ForeignKey(
  66.         "self", related_name="+", null=True, blank=True, on_delete=models.SET_NULL
  67.     )
  68.     spouse = models.ForeignKey(
  69.         "self", related_name="+", null=True, blank=True, on_delete=models.SET_NULL
  70.     )
  73. class Villain(Entity):
  74.     is_immortal = models.BooleanField(default=False)
  76.     malevolence_factor = models.PositiveSmallIntegerField(
  77.         help_text="How malevolent this villain is?"
  78.     )
  79.     power_factor = models.PositiveSmallIntegerField(
  80.         help_text="How powerful this villain is?"
  81.     )
  82.     is_unique = models.BooleanField(default=True)
  83.     count = models.PositiveSmallIntegerField(default=1)###

App events

  1.     name = models.CharField(max_length=255)
  2.     participating_heroes = models.ManyToManyField(Hero)
  3.     participating_villains = models.ManyToManyField(Villain)
  6. class Event(models.Model):
  7.     epic = models.ForeignKey(Epic, on_delete=models.CASCADE)
  8.     details = models.TextField()
  9.     years_ago = models.PositiveIntegerField()
  12. class EventHero(models.Model):
  13.     event = models.ForeignKey(Event, on_delete=models.CASCADE)
  14.     hero = models.ForeignKey(Hero, on_delete=models.CASCADE)
  15.     is_primary = models.BooleanField()
  18. class EventVillain(models.Model):
  19.     event = models.ForeignKey(Event, on_delete=models.CASCADE)
  20.     hero = models.ForeignKey(Villain, on_delete=models.CASCADE)
  21.     is_primary = models.BooleanField()

如何使用这本书

你可以把这本书从头读到尾，也可以选择你需要的章节读，每一个章节是独立的，特定的任务

无论如何，你都应该先读entities/models.py 和 events/models.py
