Question

我正在django中执行原始查询，它工作正常。但是，当我在heroku上部署它时，出现了错误。也许是因为inheroku在postgree上运行，而我做了查询才能在sqlite上运行。如果我是对的，那么我必须在查询中进行哪些更改才能正常工作？

cursor = connection.cursor()
    cursor.execute('''SELECT l_article.id, l_article.lei_id,  l_article.article, l_article.is_titulo, 
    laws_marcacao.is_marcado, laws_marcacao.description, laws_marcacao.votos, accounts_user.id , laws_marcacao.description FROM l_article 
                       INNER JOIN accounts_user 
                       LEFT JOIN laws_marcacao ON laws_marcacao.article_id = l_article.id and laws_marcacao.user_id = accounts_user.id 
                       where l_article.law_id = %s and accounts_user.id = %s;''', [law.id, request.user.id])
    data = cursor.fetchall()

那是错误：

    Traceback (most recent call last):
File "/app/.heroku/python/lib/python3.7/site-packages/django/db/backends/utils.py", line 85, in _execute
return self.cursor.execute(sql, params)
