Question

我需要一个与最多3项数据(同类数据)相联系的模式。

Here is an example:
I have candidates that need to pass 3 steps to be recruited

class Candidate(models.Model):
  user = models.ForeignKey(User)
  step1 = models.TextField(blank=True, null=True,)
  step2 = models.TextField(blank=True, null=True,)
  step3 = models.TextField(blank=True, null=True,)

每个步骤都由若干人进行审查。

class Review(models.Model):
  candidate = models.ForeignKey(Candidate)
  reviewer = models.ForeignKey(User)
  step1 = models.TextField(blank=True, null=True,)
  step2 = models.TextField(blank=True, null=True,)
  step3 = models.TextField(blank=True, null=True,)

Should I factorize these objects which would give me 4 objects instead of 2
such as Candidate, Review, CandidateStep and ReviewStep ?
- If yes, how can I limit to 3 steps ?
- If not, how can easily iterate through the steps ?

www.un.org/Depts/DGACM/index_spanish.htm 例数据:

obj, created = Candidate.objects.get_or_create(
  user = SelectedCandidate
, defaults = { step1 :   ,  step2 :   ,  step3 :   }
)
obj.step1 =  I m really motivated 
obj.step2 =  I m able to do this job 
obj.save()

obj, created = Review.objects.get_or_create(
  user = request.user
, defaults = { step1 :   ,  step2 :   ,  step3 :   }
)
obj.step1 =  He seems over motivated 
obj.save()

三个目标是什么:

class Candidate(models.Model):
    name = models.CharField(max_length=50)

class Step(model.Model):
    candidate = models.ForeignKey(Candidate)
    text = models.TextField(blank=True)

class Review(models.Model):
    reviewer = models.ForeignKey(User)
    step =  models.OneToOneField(Step)
    text = models.TextField(blank=True)

how can I limit to 3 steps ?

观点。如果您将使用<代码>ModelFromset,则使用max_num 。
