PipelineCachedStorage generates hashed files, but generated URLs do not have hashes

[john-clarke]

PipelineCachedStorage generates hashed files during collectstatic, but the generated URLs reference the files without hashes.

Example:

Post-processed 'js/app-build.js' as 'js/app-build.efa204cafb67.js'

But the rendered django template references app-build.js instead of app-build.efa204cafb67.js

STATICFILES_FINDERS = [
    'pipeline.finders.FileSystemFinder',
    'pipeline.finders.AppDirectoriesFinder',
    'pipeline.finders.PipelineFinder',
    'pipeline.finders.CachedFileFinder',
]

STATICFILES_STORAGE = 'pipeline.storage.PipelineCachedStorage' 

CACHES = {
    ...
   'staticfiles': {
      'BACKEND': 'django.core.cache.backends.locmem.LocMemCache',
      'LOCATION': 'staticfiles',
      'TIMEOUT': 3600 * 24 * 8,
      'MAX_ENTRIES': 1000,
    }
}

django = 1.10.5
django-pipeline = 1.6.12

since this is a real pain, as a dirty fix, I've wrote the following code in settings.py

if sys.argv[1:2] != ["collectstatic"]:
    css_out = STATIC_ROOT / PIPELINE['STYLESHEETS']['css_files']['output_filename']
    js_out = STATIC_ROOT / PIPELINE['JAVASCRIPT']['js_files']['output_filename']
    css_replace_done, js_replace_done = False, False
    if css_out.exists():
        for f in css_out.parent.iterdir():
            if f.name != css_out.name and css_out.stem in f.name:
                print(f'Found css versioned file: {f.name}')
                css_replace_done = True
                PIPELINE['STYLESHEETS']['css_files']['output_filename'] = PIPELINE['STYLESHEETS']['css_files']['output_filename'].replace(css_out.name, f.name)
    if js_out.exists():
        for f in js_out.parent.iterdir():
            if f.name != js_out.name and js_out.stem in f.name:
                print(f'Found js versioned file: {f.name}')
                js_replace_done = True
                PIPELINE['JAVASCRIPT']['js_files']['output_filename'] = PIPELINE['JAVASCRIPT']['js_files']['output_filename'].replace(js_out.name, f.name)
    if not css_replace_done or not js_replace_done:
        raise ValueError('css and js versioned files were not found, make sure collectstatic was called')

It tries to find the hashed files and replaces the output config, which then will be added to the template.
This code assumes one has only one css and js config with the names hard-coded.

It solved the problem for me now, but of course a proper fix from the library would be the ideal way

anyhow happy coding
