Hi,
I am trying to migrate an existing application to django. I am
encountering the following problem with this models
D:\private\james\documents\django\ksk>python manage.py validate
manning.employee: Reverse query name for field 'employee_contract'
clashes with field 'EmployeeContr
act.employee'. Add a related_name argument to the definition for
'employee_contract'.
manning.employee: Reverse query name for field 'employee_assignment'
clashes with field 'EmployeeAss
ignment.employee'. Add a related_name argument to the definition for
'employee_assignment'.
2 errors found.
class Employee(models.Model):
lastname = models.CharField(maxlength=30)
firstname = models.CharField(maxlength=30)
middlename = models.CharField(blank=True, maxlength=30)
gender = models.CharField(maxlength=1)
birthday = models.DateField()
contact_no = models.CharField(blank=True, maxlength=50)
address = models.CharField(maxlength=100)
notes = models.CharField(maxlength=200)
pay_by = models.CharField(maxlength=3, choices=PAY_BY_LIST)
hour_rate = models.DecimalField(max_digits=7,
decimal_places=2)
allowance = models.DecimalField(max_digits=7,
decimal_places=2)
account_no = models.CharField(blank=True, maxlength=20)
sss = models.CharField(blank=True, maxlength=20)
phil_health = models.CharField(blank=True, maxlength=20)
pag_ibig = models.CharField(blank=True, maxlength=20)
employee_contract = models.ForeignKey('EmployeeContract')
employee_assignment = models.ForeignKey('EmployeeAssignment')
AREA_LIST = (
('CKG', 'Cooking'),
('DLY', 'Delivery'),
('DYG', 'Drying'),
('FLA', 'Flavoring'),
('FYG', 'Frying'),
('LGS', 'Logistics'),
('MXG', 'Mixing'),
('PKG', 'Packaging'),
('ROG', 'Roasting'),
)
class EmployeeAssignment(models.Model):
employee = models.ForeignKey(Employee)
assignment_from = models.DateField()
assignment_to = models.DateField()
area = models.CharField(maxlength=3, choices=AREA_LIST)
position = models.CharField(maxlength=20)
edit_by = models.ForeignKey(Profile)
EMPLOYEE_CONTRACT_STATUS_LIST = (
('ACT', 'Active'),
('FIN', 'Finnish'),
('RES', 'Resign'),
('TER', 'Terminate'),
)
class EmployeeContract(models.Model):
employee = models.ForeignKey(Employee)
contract_to = models.DateField()
contract_from = models.DateField()
notes = models.CharField(blank=True, maxlength=200)
status = models.CharField(maxlength=3,
choices=EMPLOYEE_CONTRACT_STATUS_LIST)
edit_by = models.ForeignKey(Profile)
Although this problem can be solve with just renaming some of the
fields. I wonder if when doing some django orm operation could produce
a problem.
thanks
james
