email)

Normally when there is an error, an email is sent about the error. However
is there is a missing static file, and
**django.contrib.staticfiles.storage.ManifestStaticFilesStorage** tries to
calc the static URL, it falls over in an incredibley hard way to debug. If
your error pages require the missing static file, that is even harder.
Please consider sending an error email to the support email address if
this kind of error occurs.
Its raised in: **contrib/staticfiles/storage.py** line 417:
{{{
def stored_name(self, name):
parsed_name = urlsplit(unquote(name))
clean_name = parsed_name.path.strip()
hash_key = self.hash_key(clean_name)
cache_name = self.hashed_files.get(hash_key)
if cache_name is None:
if self.manifest_strict:
raise ValueError("Missing staticfiles manifest entry for
'%s'" % clean_name)
}}}
As a temp fix I subclassed the storage:
{{{
from django.contrib.staticfiles.storage import ManifestStaticFilesStorage
class ManifestStaticFilesWith404Storage(ManifestStaticFilesStorage):
"""If you have a manifest files error, the page to render the error
probably
has the same error, and then you can't debug it. This returns the
error
string so one can see in the rendered html there was a problem
"""
pass
def stored_name(self, name):
try:
return super().stored_name(name)
except ValueError as e:
return
f"{name}.could_not_find_static_file_to_calc_manifest_hash"
}}}
