试图读取django中的文本文件

Question

我无法从view.py中读取文件的内容

下面是我的代码：

def home_view (request, *args, **kwargs):
    ksh_test_result=AutomationTestResult.objects.values('tatr2tafmc__jobcommand', 'ksh_completion','ftp_log_abs_path','aftp_log_abs_path').distinct()
    ksh_drilldown_data=AutomationTestResult.objects.all()
    for ksh in ksh_test_result:
        ftp_log_file[ksh.tatr2tafmc__jobcommand]=open(ksh.ftp_log_abs_path, 'r').read()
        aftp_log_file[ksh.tatr2tafmc__jobcommand]=open(ksh.aftp_log_abs_path, 'r').read()
    print(ftp_log_file)
    print(aftp_log_file)
    context={
        "ksh_list" : ksh_test_result,
        "ksh_drilldown" : ksh_drilldown_data,
        "ftp_log" : ftp_log_file,
        "aftp_log" : aftp_log_file
    }
    return render(request, "home.html", context)

我正在从数据库中读取文件的路径。当我运行此代码时，出现以下错误代码

Answer 1

values返回dict的查询集，而不是模型实例；在open(ksh.ftp_log_abs_path, 'r')中，您尝试访问ftp_log_abs_path作为dict ksh的属性。
