Django mysql database credentials read_default_file giving error

Question

I am providing mySql credentials from a different conf file to django project. Earlier it was working fine, but now it stopped working after I reinstalled my ubuntu.

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

Also, the location of the conf file is as follows:

 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

The error given is as follows:

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

 django.db.utils.OperationalError: (1045, "Access denied for user 'rajiv'@'localhost' (using password: NO)")

Not able to figure out why is it giving error. If anything is wrong, can anyone suggest some other methods of doing it.

Answer 1

Well if you still want's to use options read_default_file

Then Solution is

DATABASES = {
     'default': {
         'ENGINE': 'django.db.backends.mysql',
         'OPTIONS': {
           'read_default_file': os.path.join(BASE_DIR, 'connection.cnf'),
         }
     }
 }

connection.cnf

[client]
database = test
user = root
password = rajiv@123
default-character-set = utf8

Answer 2

Try setting the permission of the config file to 644

chmod 644 connection.cnf

The problem is that because the permissions are too open, the file is ignored, and therefore you are not logged in into mysql.

Answer 3

I faced the same problem and it was pointing to the wrong path.

Try printing the path to the terminal

print(os.path.join(BASE_DIR, ''))

And then correct the path to point to the file

在密码字符串中添加双引号对我有用。
