I have a tool to create fixtures that I use in my testserver and my django tests. This tool raises the following exception:
STORAGES = {
“default”: {
“BACKEND”: “django.core.files.storage.FileSystemStorage”,
“OPTIONS” : {‘allow_overwrite’ : True}
},
“staticfiles”: {
“BACKEND”: “django.contrib.staticfiles.storage.StaticFilesStorage”,
},
}The exception is raised in django 5.2 version module functional.py in line 280. The exception does not make the tool fail but my filename 196M-1245 ADD 1245.jpeg is transformed into 196M-1245_ADD_1245.jpeg. I have very many filenames of this sort and I would very much like to solve the problem.
I thought about ovewriting the default Storage and I looked into the documentation here : How to write a custom storage class | Django documentation | Django
But I do not understand how to use this storage and how to solve this problem.
