To help myself learn Python, I'm writing a simple issue tracker using Django.
I have two simple classes (left some code out for brevity), Issue
and Version
There is an ISSUE_STATE
tuple that is used to maintain an Issue
's state:
ISSUE_STATE = (
('p', 'In Progress'),
('o', 'Open'),
('r', 'Resolved'),
('c', 'Closed'),
)
It's maintained in the Issue
like so:
class Issue(models.Model):
state = models.CharField(max_length=1, choices=ISSUE_STATE)
fix_version = models.ForeignKey(Version, related_name='issuesAsFix', null=True, blank=True, default=None)
(As you can also see, a Version
maintains a list of Issue
objects.)
The problem:
When I access the state of an individual Issue
instance, it's returned as a tuple. When I access the state of an Issue
as provided by a Version
object, it's returned as a Unicode string:
>>> v = Version()
>>> v.save()
>>> i = Issue()
>>> i.fix_version = v
>>> i.state = ISSUE_STATE[1]
>>> i.save()
>>> i.state
('o', 'Open')
>>> v.issuesAsFix.all()[0].state
u"('o', 'Open')"
>>> i == v.issuesAsFix.all()[0]
True
>>> i is v.issuesAsFix.all()[0]
False
Why is the state
variable of the Issue
a string when accessed as a child property of the Version
?
Thanks in advance!
>>> i.state = ISSUE_STATE[1]
This line is incorrect. It should be:
>>> i.state = ISSUE_STATE[1][0]
