Question

所以我试图过滤内联形式中的字段。我跟着this SO example课程和Strand正在过滤到课程，但概念不会过滤并返回所有记录。

    if db_field.name == 'course':
        kwargs['queryset'] = Course.objects.filter(pk = course_id)
    elif db_field.name == 'strand':
        kwargs['queryset'] = Strand.objects.filter(course = course_id)
    elif db_field.name == 'concepts':
        kwargs['queryset'] = Concept.objects.filter(course__id = course_id)

我正在使用的模型是：

class Indicator (models.Model):
    id = models.AutoField(primary_key=True) # AutoField?
    code = models.CharField(max_length=10)
    indicator_text = models.TextField(blank=True)
    explained = models.TextField("Explained",blank=True)
    course = models.ForeignKey('curriculum.Course')
    theme = models.ForeignKey(Theme)        
    strand = models.ForeignKey(Strand,blank=True,null=True)
    level = models.ForeignKey(Level,blank=True,null=True)
    concepts = models.ManyToManyField(Concept,blank=True)

class Course (models.Model):
 id = models.AutoField(primary_key=True) # AutoField?
 course_text = models.CharField(max_length=100, unique=True)
 slug = models.CharField(max_length=100)
 subject = models.ForeignKey(Subject)
 excerpt = models.CharField(max_length=255, unique=True)
 description = models.TextField(blank=True)     
 zorder = models.IntegerField(default=0)
 license = models.TextField("License", blank=True, null=True)
 icon = models.ImageField("Icon",upload_to='icons/',blank=True,null=True)

class Theme (models.Model):
 id = models.AutoField(primary_key=True) # AutoField?
 code = models.CharField(max_length=5)
 course = models.ForeignKey(Course)
 theme_text = models.CharField(max_length=50)
 description = models.TextField(blank=True, max_length=1000)
 zorder = models.IntegerField()

class Strand (models.Model):
 id = models.AutoField(primary_key=True) # AutoField?
 code = models.CharField(max_length=3)
 course = models.ForeignKey(Course)
 strand_text = models.CharField(max_length=50)
 description = models.TextField(blank=True, max_length=1000)

class Concept (models.Model):
 id = models.AutoField(primary_key=True) # AutoField?
 code = models.CharField(max_length=3)
 course = models.ForeignKey(Course)
 concept_text = models.CharField(max_length=50)
 description = models.TextField(blank=True, max_length=255)

这是一个已知问题还是我想要做的事情的怪癖？

一如既往地感谢您的帮助。
