Django Migrate error

Django Migrate error

I have the settings.py with Databases section configured as below:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'Mydjangoproject',
        'HOST': '',
        'PORT': '',
        'USER': 'root',
        'PASSWORD': '123456',
    }
}

Open in new window

When I run the command : python manage.py migrate

I get this output :

(py1) C:\Python-Projects\Mydjangoproject>python manage.py migrate

manage.py dbshell

Open in new window

it does not give any output

You type that in the same cmd window in which you typed

manage.py migrate

Open in new window

?

Does the window freeze or do you just get a windows prompt?

c:\yourpath>

Open in new window

You should have got something like this just with newever versions (I copied this from an old django bug as I don't have the combination windows + mysql)

C:\project>manage.py dbshell
Welcome to the MySQL monitor.  Commands end with ; or \
g.
Your MySQL connection id is 6902
Server version: 5.0.51a-community-nt-log MySQL Community Edition (GPL)
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql>

Open in new window

If the dbshell command doesn't freeze. but just does nothing, then it doesn't help diagnosing your problem (perhaps it's just mysql.exe which is missing on your PC)

Let's try then following (It might work without migrations and indicate whether the db connection works or not)

manage.py shell

Open in new window

Then within the shell type:

from django.db import connection
cursor = connection.cursor()
cursor.execute("SELECT 1 + 1 as two")
cursor.fetchall()

Open in new window

and tell me if you get any error message.

I have installed XAMPP, when I go to the browser: http://localhost/phpmyadmin, I see this:

OK this means you created a database named djangoproject. It doesn't indicate whether your credentials int the djangoconfig are correct.

The information visibile in this question suggests, that the database configuration might not be correct. so that's what I'd concentrate on until there's other elements indicating the problem is something else.

Please answer all of my following questions in order to avoid too many iterations.

Q1: can you install a mysql command line client on your machine?
Q1a: if yes, can you connect to your data base with the command line client.

Q2: What do you see if you type my previously suggested commands in the django management.py shell?

Q3: Is the django server located on the same server than phpmyadmin?

Q4: if it is, then you could try to replace "localhost" in the django settings with "127.0.0.1" or vice versa and retry

How do you install it ?

Normally if you install mysql on windows (e.g. from https://dev.mysql.com/downloads/installer/ ) You should have somehwere an executable called `mysql.exe`

I don't use windows that often, so I don't know whether it will be in the search path or whether you have to call it with its absolute path name.

if you found this command line client you should be able to call it with

mysql.exe dbname

Open in new window

or with

mysql.exe --user=user_name --password db_name

Open in new window

or with

mysql.exe --user=user_name --password --host=hostname db_name
