Question

The result gave me :

In template d:\python\project\tpl\base.html, error at line 68 Caught TypeError while rendering: not enough arguments for format string

Answer 1

The raw SQL is a string with formatting parameters, which means that % indicates a parameter to format. Your string has % in it. You need to double them to protect them from interpretation:

diary = models.SablogArticles.objects.raw("""
    SELECT 
        articleid, 
        DATE_FORMAT(from_unixtime(dateline),'%%Y-%%m') as newtime,
        count(*) as howmany
    FROM sablog_articles group by newtime
    """)
