我試圖創建一個Department
& Ticket
表之間的一對一關係。這樣,在Flask-Admin
內部查看時,用戶將能夠看到名稱Department
而不是ID。創建一對一的關係Flask-SQLAlchemy
我試圖建立的關係如下:
# Ticket Table
class Tickets(db.Model):
__tablename__ = 'tickets'
ticketID = db.Column(db.Integer, nullable=False, primary_key=True, autoincrement=True, unique=True)
cust_name = db.Column(db.String(50), nullable=False)
cust_email = db.Column(db.String(50), nullable=False)
cust_phone = db.Column(db.Integer, nullable=False)
tix_dept = db.Column(db.Integer, db.ForeignKey('department.deptID'))
tix_severity = db.Column(db.Integer, nullable=False)
tix_msg = db.Column(db.String(500), nullable=False)
tix_status = db.Column(db.String(10), nullable=False)
tix_recv_date = db.Column(db.String(20), nullable=False)
tix_recv_time = db.Column(db.Integer, nullable=False)
# define relationship
department = db.relationship('Departments')
# Department Table
class Departments(db.Model):
__tablename__ = 'department'
deptID = db.Column(db.Integer, primary_key=True, autoincrement=True, unique=True)
dept_name = db.Column(db.String(40), nullable=False)
dept_empl = db.Column(db.String(40), nullable=False)
dept_empl_phone = db.Column(db.Integer, nullable=False)
然後我Flask-Admin
的觀點是:
admin.add_view(TicketAdminView(Tickets, db.session, menu_icon_type='glyph', menu_icon_value='glyphicon-home'))
admin.add_view(DepartmentAdminView(Departments, db.session))
的管理控制檯門票:
我怎麼會去展示Department
名稱,而不是存儲位置?

department = db.relationship('Departments',backref = backref(「tickets」,uselist = False))' uselist = False可能會修復您的視圖問題以及 – brennan
