I am altering an existing application so I can expand the use case a bit. I have already created a new model and altered the view and template a bit. Now I want to run migrations, but I keep getting the NameError and a Google search didn't provide me with much more information, especially since I am adding things to a working application rather than creating something from scratch. Is anyone able to help me?
I have added the following line to admin.py: admin.site.register(InputData)
the error:
C:\var\www\SYSTEM>python manage.py makemigrations

EDIT: I have solved it myself. Turns out there was an 'init' file where all models had to be referenced in order to use them in Admin.
这很可能意味着您没有在admin.py文件中导入“ InputData”。
The last two lines of your error give me the idea that you might have forgotten to import 'InputData' class in admin.py file.
File "C:\var\www\SYSTEM\System\service_development\admin.py", line 201, in <module>
admin.site.register(InputData)
NameError: name 'InputData' is not defined
Import 'InputData' class in admin.py and you are good to go :)
