and i have added template_dir in DIRS

Please help me in resolving this error

The TEMPLATE_DIRS setting was deprecated back in Django 1.8.

The current method for defining templates is the TEMPLATE setting.

I have updated the above post by using templates ,you can check ,is this you are talking, it is not working

In what directory is your emp.html file located?

The directory structure is templates/testApp/emp.html

Is it EMPproject/testApp/templates/testApp/emp.html or
EMPproject/templates/testApp/emp.html?

The first should be picked up by the APP_DIRS: True setting, the second should be found because of being in the DIRS list. If it is the second, you might want to check to verify that your TEMPLATE_DIR is what you’re expecting it to be.

Also, you mention that you’re using Django 3.0. Which subversion of 3.0 are you using? Python 3.9 is not officially supported until 3.0.11 - if you’re using an earlier version, you might want to bring it up to date.

Thanks for helping, the issue was resolved
