我目前有两个独立的模型(如下所示),这两个模型适用于我的应用程序的小规模/测试。然而,当有超过5000名客户时,通过FK下拉框进行搜索将会在每次输入注释时都会很麻烦。
我的问题是,有没有什么方法可以将Note模型放在我的客户模型中?这样我就可以从我的客户模型中直接添加备注了?
#models.py
samples_to_customer = Table('samples_to_customer', Base.metadata,
Column('customer_id', Integer, ForeignKey('customer.id')),
Column('sample_id', Integer, ForeignKey('samples.id'))
)
#Create a cusotmer model to store customer numbers
class Customer(Base):
__tablename__ = 'customer'
__acl__ = [
(Allow, 'admin', ALL_PERMISSIONS),
(Allow, 'saff', ('view', 'edit')),
]
id = Column(Integer, primary_key=True)
name = Column(Unicode, unique=True) #this will be the variable used to search the existing db
customer_samples = relationship('Sample', secondary='samples_to_customer', backref='samples')
sales_rep = Column(Integer, ForeignKey('rep.id'))
rep = relationship('Rep', backref='rep')
def __unicode__(self):
return self.name
# This model will have its own entry view/page a user logs on and enters notes (according to a customer
# number) they then get stored/saved onto the Customers account
class Note(Base):
__tablename__ = 'note'
__acl__ = [
(Allow, 'admin', ALL_PERMISSIONS),
(Allow, 'staff', ('view', 'edit')),
]
id = Column(Integer, primary_key=True)
name = Column(Unicode)
pub_date = Column(Date)
customer_no = Column(Integer, ForeignKey('customer.id'))
customer = relationship('Customer', backref='notes')
def __unicode__(self):
return self.name发布于 2012-03-21 21:38:05
我没有找到任何方法来做这件事。
但是我对金字塔和形式化学还是很陌生的。
我已经决定编写我自己的管理/模型界面,让我用金字塔视图和jinja2模板做我需要做的事情。而不使用formalchemy和/或javascript。
我来自django,所以我没有意识到编写我自己的模型管理视图和模板是多么容易。
