    user = models.ForeignKey(User) 

    #applicant = models.ForeignKey(Applicant) 
    skill = models.ForeignKey('skills_layer.Skill') 
    active = models.BooleanField(default=True) 

class Job_Posting(models.Model): 
    company = models.ForeignKey('companies_layer.Company', default=-1) 
    job_posted_by = models.ForeignKey(User, default=-1) 
    job_title = models.CharField(max_length=100)

    class Meta: 
     verbose_name = "job posting" 

    def __str__(self): 
     return self.job_title

     resource_name = 'jobs' 

今天是第一天，我想Tastypie所以請善待與我:(

JobListingResource返回所有的工作列表。但我只想得到那些工作列表其中Tags列包含登錄用戶的skill列中的值。

例如：如果用戶「A」已經登錄並具有以下技能「python，django，jquery」。我希望JobListingResource僅返回tags列中包含[python/django/jquery]的記錄。

我假設你知道如何做這些查詢，只需要知道在Tastypie中做什麼。在你的JobListResource覆蓋如下：

def get_object_list(self, request): 

    # get all the jobs according to the queryset in Meta 
    base = super(JobListingResource, self).get_object_list(request) 

    # and add a filter so only users ones appear 
    user = request.user 
    skills = query to get all the skills for the user 
    return base.filter(filter to apply to JobPosting to only return jobs matching skills list)
