反向关系在django模型中不起作用？

我有以下疑问

SELECT DISTINCT P.intPartID FROM tbmstpart p, tbtrnappraisalquestion q WHERE p.intPartID = q.intPartID AND q.intTemplateID =4

我的模特是

class tbmstpart(models.Model):
intPartID = models.AutoField(primary_key=True,db_column="intPartID")
vchPartname = models.CharField("PartName", max_length=50,db_column="vchPartname")
def __unicode__(self):
    return self.vchPartname
class Meta:
    db_table = 'tbmstpart'
    verbose_name = 'PartName'
    verbose_name_plural = 'PartNames'

class tbmstsection(models.Model):
intSectionID = models.AutoField(primary_key=True,db_column="intSectionID")
vchSectionName = models.CharField("SectionName", max_length=50,db_column="vchSectionName")
def __unicode__(self):
    return self.vchSectionName
class Meta:
    db_table = 'tbmstsection'
    verbose_name = 'SectionName'
    verbose_name_plural = 'SectionNames'

class tbtrnappraisalquestion(models.Model):
STATUS = (
    ('1','Yes'),
    ('0','No')
)
intQuesID = models.AutoField(primary_key=True,db_column="intQuesID")
intTemplateID= models.ForeignKey(tbmsttemplate,verbose_name="Template",db_column="intTemplateID",related_name="tbmsttemplate_intTemplateID")
intSectionID= models.ForeignKey(tbmstsection,verbose_name="Section",db_column="intSectionID",related_name="tbtrnappraisalquestion_intSectionID")
intPartID= models.ForeignKey(tbmstpart,verbose_name="Part",db_column="intPartID",related_name="tbtrnappraisalquestion_intPartID")
txtQuestion = models.TextField("Question",db_column="txtQuestion")
#txtQuestion = RichTextField()
enumRating = models.CharField("Rating",max_length=5,choices=STATUS,db_column="enumRating")
enumComment = models.CharField("Comment",max_length=5,choices=STATUS,db_column="enumComment")
intOrder = models.CharField("Sequence",max_length=2,db_column="intOrder")
def __unicode__(self):
    return self.txtQuestion
class Meta:
    db_table = 'tbtrnappraisalquestion'
    verbose_name = 'AppraisalQuestion'
    verbose_name_plural = 'AppraisalQuestions'

我试过这样做

parts_list = tbmstpart.objects.filter(tbtrnappraisalquestion__intTemplateID__exact=4)

但这是一个错误

在/opas/list\u测试中出现字段错误/ 无法将关键字“TBTrnapraisalQuestion”解析到字段中。选项包括：intPartID、TBTrnapraisalQuestion\u intPartID、vchPartname

提前感谢？

您在

tbtrnappraisalquestion\uuuu intTemplateID

中输入了

\uuuuuuuu

，而您想要的是

tbtrnappraisalquestion\u intTemplateID

将您的查询更改为

假设您的

tbmstmplate

模型将

intTemplateID

作为int主键

parts_list = tbmstpart.objects.filter(tbtrnappraisalquestion_intPartID__intTemplateID__intTemplateID__exact=4)
#there is no typo here, you have to do __intTemplateID__intTemplateID as your pk field in `tbmsttemplate` and FK `tbtrnappraisalquestion`  are same

正如@Rohan所说，我试过这个。工作正常

parts_list = tbmstpart.objects.filter(tbtrnappraisalquestion_intPartID__intTemplateID__exact=4).distinct()

我照你说的做了。但它抛出了一个错误，无法将关键字“tbtrnappraisalquestion\u intTemplateID”解析到字段中。选项有：intPartID、TBTrnapraisalQuestion\u intPartID、VCHPartName谢谢您的帮助。但是你能不能把tbtrnappraisalquestion\u intPartID\u intTemplateID\u intTemplateID\u精确=4。
