Question

我使用haystack-solr进行搜索，我想做的是当一个人搜索教育时它显示用户的所有数据是外键我的模特：

class user_info(models.Model):

    gender= (

        ('Male',_('Male')),
        ('Female',_('Female')),

    )
    user_id = models.AutoField(primary_key=True)
    first_name = models.CharField(verbose_name=_('First Name'),max_length=100, null=True, blank=True)
    last_name = models.CharField(verbose_name=_('Last Name'),max_length=100, null=True, blank=True)
    industry_id = models.ForeignKey(industry,verbose_name=_('Industry ID'),to_field = 'industry_id',  null=True, blank=True)
    functional_area_id = models.ForeignKey(functional_area,verbose_name=_('Functional Area'),to_field = 'functional_area_id',  null=True, blank=True)
    city = models.CharField(verbose_name=_('City'),max_length=100, null=True, blank=True)
    country= models.ForeignKey(Country,verbose_name=_('Country'),to_field = 'country_name',  null=True)
    phone_number1 = models.CharField(verbose_name=_('Phone Number 1'),max_length=100, null=True, blank=True)
    phone_number2 = models.CharField(verbose_name=_('Phone Number 2'),max_length=100, null=True, blank=True)
    phone_number3 = models.CharField(verbose_name=_('Phone Number 3'),max_length=100, null=True, blank=True)
    cnic = models.CharField(verbose_name=_('Citizen National Identity Card'),max_length=100, null=True, blank=True)
    dob =    models.DateField(verbose_name=_('Date of Birth'))
    gender =    models.CharField(verbose_name=_('Gender'),max_length=255, choices=gender,default='Male')


    def __unicode__(self):
        #return self.user
        return unicode(self.first_name)

admin.site.register(user_info)

class resume(models.Model):

    user_id = models.ForeignKey(user_info,verbose_name=_('User ID'),to_field = 'user_id',  null=True, blank=True)
    resume_id = models.AutoField(primary_key=True)

    def __unicode__(self):
        #return self.user
        return unicode(self.resume_id) 

admin.site.register(resume)

class education(models.Model):

    education_id = models.AutoField(primary_key=True)
    resume_id = models.ForeignKey(resume,verbose_name=_('Resume ID'),to_field = 'resume_id',  null=True, blank=True)
    title = models.CharField(verbose_name=_('Degree Title'),max_length=100, null=True, blank=True)
    educational_level_id = models.IntegerField (verbose_name=_('Educational Level ID'),max_length=255,null=True)
    institute = models.CharField(verbose_name=_('Institute'),max_length=100, null=True, blank=True)
    start_date =    models.DateField(verbose_name=_('Start date'),null=True)
    end_date =      models.DateField(verbose_name=_('End date'),null=True)
    cgpa = models.DecimalField(verbose_name=_('CGPA'),max_digits=10,decimal_places=2,default="0.00")
    percent = models.DecimalField(verbose_name=_('Percent'),max_digits=10,decimal_places=2,default="0.00")
    majors = models.CharField(verbose_name=_('Majors'),max_length=2000, null=True, blank=True)

    def __unicode__(self):
        #return self.user
        return unicode(self.title)

admin.site.register(education)

我的search_indexes.py

class resume(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)
    user_id = indexes.MultiValueField()

    def prepare_resumes(self, obj):
        # Use the relation and hang the id's off it.
        return [user_info.user_id for user_id in obj.user_info.all()] 

    def get_model(self):
        return resume


class UserIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)
    city = indexes.CharField(model_attr='city')
    dob = indexes.CharField(model_attr='dob')
    first_name = indexes.CharField(model_attr='first_name')
    last_name = indexes.CharField(model_attr='last_name')
    phone_number1 = indexes.CharField(model_attr='phone_number1')
    phone_number2 = indexes.CharField(model_attr='phone_number2')
    phone_number3 = indexes.CharField(model_attr='phone_number3')
    cnic = indexes.CharField(model_attr='cnic')
    gender = indexes.CharField(model_attr='gender')
    resumes = indexes.MultiValueField()

    def get_model(self):
        return user_info

class EducationIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)
    title = indexes.CharField(model_attr='title')
    educational_level_id = indexes.CharField(model_attr='educational_level_id')
    institute = indexes.CharField(model_attr='institute')
    cgpa = indexes.CharField(model_attr='cgpa')
    percent = indexes.CharField(model_attr='percent')
    majors = indexes.CharField(model_attr='majors')
    resume_id = indexes.MultiValueField()

    def prepare_resumes(self, obj):
        # Use the relation and hang the id's off it.
        return [resume.resume_id for resume_id in obj.resume.all()] 

    def get_model(self):
        return education

现在这是一对多的关系，如果我搜索用户，它应该向我显示用户以及教育信息，当我搜索教育时，它应该向我显示用户信息。怎么办呢？

在搜索haystack中显示子模型数据
