please help i am stuck

2

The key information about this error is on the very last line. What do you think this error is telling you?

3

it is suggesting to choose one either storage/storage_default_file

i dont see where is this file to located , it is a old project, i cant remember the file name , i used grep -rl with that error in the Noc dir , i dont see anywhere hence why i wanted help by an expert?

4

These are configuration settings in your settings.py file. Look for the two entries shown in the error message. See DEFAULT_FILE_STORAGE and STORAGES

5

I dont have the file settings.py rather base.py and local.py

6

Ok, whatever - it’s in the file(s) where your settings are.

7

can give the content ? it wasnt there i added it after the encoutered that errorr

8

I don’t understand your question.

9

cant share the content of the code? and I am saying the storage div was added by me when I encountered that error.

hence why i said i dont see where it was located at first.

my big problem is to locate where storage file is setup … you mentioned usually in settings.py i dont have, I have local.py in settings directory

10

The name of the file for the settings isn’t important - you can make it whatever you want.

What’s important are the contents of that file.

Look for those two entries in whatever file it is that you are storing your settings in.

11

thanks. it seems i dont have that setup, could i have a sample guide of how it has to be ?

12

Please post the contents of your settings files and of your manage.py file.

thanks:

What is this?

(What is the InstallationParameter in the that file?)

16

Note: You should not have this line:

Quoting directly from the docs at Django settings | Django documentation | Django

Note that a settings file should not import from global_settings , because that’s redundant.

17

Thinking about this some more, what I would recommend is that you get a known-good settings file (perhaps the one created by “startproject”, and change it to add your specific requirements here for this environment. Then, once you’ve validated the settings, go ahead and recreate the structure your using now, starting from that validated base.

thank you I will revert back tomorrow it is midnight here thank you so so much o far

19

Hi dear,

where do i define my storage and how to reference it ? any links or doc ?

20

The docs are in the links above at error when running manage.py migrate - #4 by KenWhitesell

The definitions belong in your settings file.
