django - 查看我的 Django 模型 - 需要很多建议

Question

我正在收集各种信息源来建立一个人的文件。一旦我这样做了，我想灵活地以不同的方式看待一个人。我在 Django 中没有太多经验，所以我想对我的模型进行批评(温和)。诚然，即使我编写了这个代码，我也在考虑冗余(反对 DRY)，但我想知道其他人的想法。 FWIW - 这些数据是拉取的而不是创建的 - 所以也许我不应该保留所有数据但删除数据似乎很糟糕..

具体来说，我想知道 ManyToMany 的使用是否合适，或者您是否只是 KISS 并将每个条目保留为自己的条目而没有任何 ManyToMany 业务。从长远来看，我认为 KISS 会使它的更新变得简单(一个基本的 for 循环)，但是在能够查询一个人(比如基于 location_description 或 job_function)方面是否存在权衡。无论如何，我将不胜感激。

class Person(models.Model):

    """This simply builds a notes user"""

    aliases = models.ManyToManyField(Aliases)  #Hmm this is list..
    assistant = models.CharField(max_length = 255, blank = True)
    cell_phone = models.CharField(max_lenth = 16, blank = True)
    city = models.ManyToManyField(City)
    country = models.ManyToManyField(County)
    department = models.ManyToManyField(Department)
    departmeht_number = models.ManyToManyField(Department_Number)
    division_code = models.ManyToManyField(Division_Code)
    email = models.EmailField(max_length = 50)
    functional_area = models.ManyToManyField(Functional_Area)
    # jpeg = models.
    job_classification = models.ManyToManyField(Job_Classification)
    job_classification_code = models.ManyToManyField(Job_Classification_Code)
    last_name = models.CharField(max_length = 255)
    location_description = models.ManyToManyField(Location_Description)
    location_path = models.ManyToManyField(Location_Path)
    mail_address = models.CharField(max_length = 255, blank = True)
    mail_domain = models.ManyToManyField(Mail_Domain)
    mail_file = models.CharField(max_length = 255, blank = True)
    mail_server = models.ManyToManyField(Mail_Server)
    match_pct = models.CharField(max_lenth = 6)
    name = models.CharField(max_length = 255)
    name_reverse = models.CharField(max_length = 255)
    nickname = models.CharField(max_length = 32)
    notes_url = models.URLField()
    #    object_class = models.
    office_phone = models.CharField(max_length = 255, blank = True)
    other_phone = models.CharField(max_length = 255, blank = True)
    position = models.ManyToManyField(Position)
    section = models.ManyToManyField(Section)
    section_code = models.ManyToManyField(SectionCode)
    shift = models.ManyToManyField(Shift)
    state = models.ManyToManyFiedl(State)
    supervisor = models.ManyToManyField(Supervisor)
    supervisor_reverse = models.ManyToManyField(Supervisor_reverse)
    uid = models.CharField(max_length = 128)

    def __unicode__(self):
        return str(self.name)

Answer 1

__unicode__ 应该返回 unicode

def __unicode__(self):
       return u'%s' %self.name

Django 为完整地址提供了一个电子邮件字段:

mail = models.EmailField()

我认为，地址模型可能是有意义的。一个人可以有多个地址(工作、家庭……)

我刚刚看到，您正在使用 emailfield。

这是做什么用的:

mail_address = models.CharField(max_length = 255, blank = True)
mail_domain = models.ManyToManyField(Mail_Domain)
mail_file = models.CharField(max_length = 255, blank = True)
mail_server = models.ManyToManyField(Mail_Server)

?

您不必一直使用 ManyToManyFields。查看 ForeignKey、OneToOneField 和通用框架
