当我今天想在服务器上部署django项目时,我一直坚持这个过程.当我python manage.py runserver在服务器上运行时,终端显示我:

Traceback (most recent call last):

我曾经ps ax | grep mysql检查过mysql进程是否存在，我发现

5323 s000 S+ 0:00.00 grep mysql .

我想终止该进程，但数字自动更改。

当我进入时ps ax | grep mysql，内容改变了

5507 s000 S+ 0:00.00 grep mysql

顺便说一句，我已经尝试过删除 mysql 的方法，这是互联网上最流行的方法。但是mysql进程还在我的电脑上。

任何人都可以给我一个提示，将不胜感激。

现在我可以在使用 Click_Data 模型时使用 list_display() 来显示列词和click_times。代码如下：

# models.py
class Click_Data(models.Model):
    word = models.CharField(max_length=255)
    click_times = models.IntegerField(default=0)

    class Meta:
        ordering = ('word',)

    def __unicode__(self):
        return self.word  

# admin.py
    class Click_DataAdmin(admin.ModelAdmin):
        fieldsets = [
            ('Word',    {'fields': ['word']}),
            ('Number',  {'fields': ['click_times']}),
        ]
        list_display = ('word', 'click_times')

但是我不知道在使用User_Data 模型（如下）时如何使用 list_display( ) 来显示列词和click_times。

# models.py
class User_Data(models.Model):
    user = models.ForeignKey(User)
    click_data = models.ForeignKey(Click_Data)

    class Meta:
        ordering = ('user',)

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

# admin.py
class User_DataAdmin(admin.ModelAdmin): …
