Django 4.0 File Not Found Error

[aibharata]

I'm trying to run drf-yasg with Django 4.0 and Whitenoise.
I keep getting file not found errors shown below when I run python manage.py collectstatic. Any suggestions how to solve this?

whitenoise.storage.MissingFileError: The file 'drf-yasg/redoc-old/redoc.min.map' could not be found with <whitenoise.storage.CompressedManifestStaticFilesStorage object 

The JS file 'drf-yasg/redoc-old/redoc.min.js' references a file which could not be found:
 drf-yasg/redoc-old/redoc.min.map

Try to change the storage to
STATICFILES_STORAGE = 'whitenoise.storage.CompressedStaticFilesStorage'
If it works, then it is a whitenoise related issue, better to report it on their repo.

whitenoise.storage.CompressedStaticFilesStorage

That also didn`t work. I had used the below settings with drf-yasg, Python37, and Django 3+ versions without any problems for a long time.

STATICFILES_STORAGE = "whitenoise.storage.CompressedManifestStaticFilesStorage"

Seems like redoc.min.map is not generated in Django 4.0 version.

Also facing the same problem:

django==3.2.8
whitenoise==5.3.0
drf-yasg==1.20.0

Gracias @m-nagy funciono para django 4.0

[diogosilva30]

@dalokdaga upgrading to django 4.0 did not work for me.
Can you share the exact versions you are using (django, whitenoise, drf-yasg)?

[dalokdaga]

@spamz23 my config is this, i hope you have luck....

-----requirements------
Django==4.0
whitenoise==5.3.0
drf-yasg==1.20.0

--------settings--------

MIDDLEWARE = [
...
'whitenoise.middleware.WhiteNoiseMiddleware',
]

STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')
STATICFILES_STORAGE = 'whitenoise.storage.CompressedStaticFilesStorage'

Having the same issue with django 4 but without whitenoise. Worked well with django 3.

https://docs.djangoproject.com/en/4.0/ref/contrib/staticfiles/#manifeststaticfilesstorage is why it's broken, js map file is searched for.

 File "/envs/roomstorm/lib/python3.8/site-packages/django/contrib/staticfiles/storage.py", line 97, in hashed_name
    raise ValueError("The file '%s' could not be found with %r." % (filename, self))
ValueError: The file 'drf-yasg/redoc-old/redoc.min.map' could not be found with <django.contrib.staticfiles.storage.ManifestStaticFilesStorage object at 0x7f892c50de50>.

Check this ticket in Django: https://code.djangoproject.com/ticket/33353. A work-around is to update static files storage backend

class NoSourceMapsStorage(ManifestStaticFilesStorage):
    patterns = (
        (
            "*.css",
            (
                "(?P<matched>url\\(['\"]{0,1}\\s*(?P<url>.*?)[\"']{0,1}\\))",
                (
                    "(?P<matched>@import\\s*[\"']\\s*(?P<url>.*?)[\"'])",
                    '@import url("%(url)s")',
                ),
            ),
        ),
    )

Changing whitenoise.storage.CompressedManifestStaticFilesStorage to whitenoise.storage.CompressedStaticFilesStorage as suggested by @dalokdaga worked for me.

If I install from source on master branch (with pip install git+https://github.com/axnsan12/drf-yasg#egg=drf-yasg), the collectstatic almost works, except there is one small mistake left, which I fixed in #778

It happens with Node.js scripts

I had the same problem, don't know if it;s still actual, but found the solution for me.
The problem was in the min.js files , django cacheing seems to find trouble with this kind of files.
So I ended with 2 solutions:

1. If you use some npm js with all it's imports and features try to use django-compressor django-compressor-toolkit see Using Node.js With Django
2. Try to use a cdn instead, or if is a Github repo, try https://raw.githubusercontent.com/[user]/[repo]/[file]

Hope this will help you, please react if helps it's useful to know if I'm right

This is caused by Django 4.0+ updating its staticfiles collection to also modify source map comments to "mangled" urls that include content hashes in the filename. The files distributed by current latest drf-yasg (1.20.0) includes scripts with source map comments, but does not include the source maps themselves. A quick work-around for Django 4.0 with continuing to use one of the Manifest staticfiles storage classes, is to simply add empty files for the map files in one of your static directories. For drf-yasg, the missing files are:

drf-yasg/redoc-old/redoc.min.map
drf-yasg/redoc/redoc.standalone.js.map
drf-yasg/swagger-ui-dist/swagger-ui-bundle.js.map
drf-yasg/swagger-ui-dist/swagger-ui-es-bundle-core.js.map
drf-yasg/swagger-ui-dist/swagger-ui-es-bundle.js.map
drf-yasg/swagger-ui-dist/swagger-ui-standalone-preset.js.map

Because the collectstatic command looks in all the static folders configured, it doesn't matter if these are included in the upstream package, as long as they are included somewhere. The next release should be sure to either include dist static files without these source map comments, or keep the comments and also distribute the *.map files (or, do both).

changing the STATICFILES_STORAGE from whitenoise.storage.CompressedManifestStaticFilesStorage to whitenoise.storage.CompressedStaticFilesStorage works for me.

Can this be closed now, since #778 is merged?

[JoelLefkowitz]

@pandafy absolutely, thanks for pointing this out.
