This article introduces the relevant knowledge of "error summary of Django2.1 integrated xadmin management background". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

By default, django has an admin background management module, but it is ugly and the functions are not complete, but the great god has integrated the xadmin background for us, and we can use it. However, django has been upgraded to version 2.1, and xadmin does not seem to be able to keep up with the pace, so in the process of integration, we will fill the hole step by step. This is also a process of learning, encountered mistakes and found the wrong places. Take a look at the latest django upgrades that have been modified, get rid of those, and replace the corresponding errors.

Xadmin source code address: https://github.com/sshwsfc/xadmin

Download and extract:

We are using the xadmin folder, which copies xadmin to the root directory of the project, at the same level as the project.

Install dependent libraries:

Activate the virtual environment of the project, cd to the extracted xadmin-master directory, and run the code

Pip3 install-r requirements.txt

Introduce: in the project settings.py settings file:

Set in the urls.py of the project

Then run: python manage.py makemigrations to set up the database migration file

At this time, it will lead to a series of error tips.
