模型.py：

from django.db import models

class Line(models.Model):
  text = models.CharField(primary_key=True, max_length=255)

class Line2 (models.Model):
  text_line = models.ForeignKey ("Line", primary_key = True)

视图.py：

from django.core.context_processors import csrf
from django.shortcuts import render

from models import Line, Line2

def test_page (request):
  if 'uid' in request.POST:
    user_id = request.POST['uid']

    return render(request, "templateFiles/testPage1.html", {"page_result":"Data Entered"});
  else:
    return render(request, "templateFiles/testPage1.html")

模板：

<div id = "header">

我正在从Django项目的另一个conf文件中提供mySql凭据。之前它可以正常工作，但是现在在我重新安装Ubuntu后它停止了工作。

settings.py：

 DATABASES = {
     'default': {
         'ENGINE': 'django.db.backends.mysql',
         'OPTIONS': {
           'read_default_file': './connection.cnf',
         }
     }
 }

connection.cnf：

 [client]
 database=test
 user=root
 password=rajiv@123
 HOST=localhost
 PORT=3306
 default-charset=utf8

另外，conf文件的位置如下：

 rajiv@ubuntu:~/djangoProjects/test$ ls -l
 total 9
 drwxrwxrwx 1 root root 4096 Dec 28 11:04 test
 drwxrwxrwx 1 root root 4096 Dec 27 14:00 testApp
 -rwxrwxrwx 1 root root  103 Dec  3 00:37 connection.cnf
 -rwxrwxrwx 1 root root  252 Oct 15 11:36 manage.py

给出的错误如下：

 rajiv@ubuntu:~/djangoProjects/test$ python manage.py runserver
