I migrated the Django database model to MySQL. When I tried to access the data in MySQL, I can’t seem to find my existing data. How can I fix this?
Migration code:
settings.py:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'sample',
'USER': '********',
"PASSWORD": '********',
'HOST': '*****',
'PORT': '*****',
'OPTIONS': {
'sql_mode': 'traditional',
}
}
}
models.py
from django.db import models
import os
from PIL import Image
from datetime import date
import datetime
from .validators import validate_file_extension
import base64
from django.utils.functional import cached_property
from django.utils.html import format_html
def get_directory_path(instance, filename):
today = date.today()
t = datetime.datetime.now()
day, month, year = today.day, today.month, today.year
hour, minutes, seconds = t.hour, t.minute, t.second
filename = str(day) + str(month) + str(year) + str(hour) + str(minutes) + str(seconds) + '.png'
dir = 'media'
path = '{0}/{1}'.format(dir, filename)
return path
class Image(models.Model):
image = models.FileField(upload_to = get_directory_path, null = True , validators=[validate_file_extension])
created_date = models.DateTimeField(auto_now = True)
def __str__(self):
return str(self.id)
After this, I typed:
python manage.py makemigrations python manage.py migrate
Everything seems to work well but I’m not able to view my data. Any suggestions?
Answer
Were you using sqlite before? After changing the database and migrating only the database schemas(tables) are made in MySql. You will loose all your data from before and cannot retrieve it.
