Django的選擇不同領域的工作不

我有2種型號：Django的選擇不同領域的工作不

class Team(models.Model): 
     """ 
     Team model for creating a basic team. 
     """ 
     image = ThumbnailerImageField(upload_to=_profile_image_directory(), verbose_name=u'Logo', help_text=u'Uploading a team logo is highly recommended.', blank=True) 
     name = models.CharField(verbose_name=u'Team Name', max_length=100) 
     school = models.CharField(verbose_name=u'School Name', max_length=100, blank=True) 
     city = models.CharField(max_length=100, blank=True) 
     state = USStateField(blank=True) 
     description = models.CharField(blank=True, max_length=175) 
     members = models.ManyToManyField(User, through='TeamMember') 
     key = models.CharField(max_length=8, unique=False, blank=True) 
     private = models.BooleanField(blank=True) 
     twitter = models.CharField(verbose_name=u'Twitter handle', max_length=15, blank=True) 
     hashtag = models.CharField(help_text=u'Tweets containing this hashtag will be pulled into your team\'s Twitter feed', max_length=20, blank=True) 

     def __unicode__(self): 
       return u'%s' % (self.name) 

     class Meta: 
       verbose_name = u'Team' 
       verbose_name_plural = u'Teams' 
       unique_together = ('name', 'school', 'state') 

class TeamMember(models.Model): 
     """ 
     Team model for connecting users with teams. 
     """ 
     user = models.ForeignKey(User) 
     team = models.ForeignKey(Team) 
     number = models.PositiveIntegerField(max_length=3, blank=True, null=True) 
     position = models.CharField(max_length=100, blank=True) 
     start = models.CharField(help_text=u'Year only. Format: 2004', max_length=4, blank=True) 
     end = models.CharField(help_text=u'Year only. Leave blank for current team', max_length=4, blank=True) 
     created = models.DateTimeField(auto_now_add=True) 
     updated = models.DateTimeField(auto_now=True)

我試圖尋找所有的名字當前用戶的隊友，所以我這裏有一個查詢：

TeamMember.objects.filter(team__members=request.user).filter(user__username__icontains=query).exclude(user=request.user)

此查詢有效，但如果該用戶與您在幾個相同的團隊中，我會多次獲得重複用戶，所以我想在用戶字段上執行DISTINCT或GROUP BY，但我嘗試的所有操作都不起作用。

我已經試過：

TeamMember.objects.filter(team__members=request.user).filter(user__username__icontains=query).exclude(user=request.user).distinct("user")

這一個工作，但並沒有給我足夠的信息對用戶，只是他們的ID，因爲它被轉換成一個字典：

TeamMember.objects.filter(team__members=request.user).filter(user__username__icontains=query).exclude(user=request.user).values("user").distinct()

有什麼想法嗎？

我的回答有助於解決您的問題？我可以改進它嗎？讓我知道如果這是一個錯誤的答案，以解決它。 – danihp 2012-01-13 20:46:54

您的查詢返回截然不同的TeamMember不明顯user。

爲了得到不同user：

user.objects.filter( 
       teammember__team__teammember__user__icontains=query 
     ).exclude(user=request.user).distinct()

解釋：distincts users他們teammember有關係到一個teammember具有user包含query這一切不含登錄用戶team。
