Mezzanino - Impossibile caricare css e js in Heroku

Question

Sto riscontrando alcuni problemi nell'hosting di un semplice sito Web che ho creato in Heroku. Il sito Web è stato creato utilizzando Mezzanine e utilizza whitenoise e gunicorn. Il problema è: sto ricevendo errore 404 in alcune risorse statiche, come css e js. Puoi vedere i problemi allo http://blrg-advogados.herokuapp.com.

Questo è il contenuto Procfile:

web: python manage.py collectstatic --noinput; gunicorn --workers=4 site_advogados.wsgi 0.0.0.0:$PORT 

wsgi.py

import os 

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "site_advogados.settings") 

from django.core.wsgi import get_wsgi_application 
from whitenoise.django import DjangoWhiteNoise 

application = get_wsgi_application() 
application = DjangoWhiteNoise(application) 

e qui è una parte di settings.py:

ALLOWED_HOSTS = ['*'] 
DEBUG = False 
PROJECT_APP_PATH = os.path.dirname(os.path.abspath(__file__)) 
PROJECT_APP = os.path.basename(PROJECT_APP_PATH) 
PROJECT_ROOT = BASE_DIR = os.path.dirname(PROJECT_APP_PATH) 
CACHE_MIDDLEWARE_KEY_PREFIX = PROJECT_APP 
STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage' 
STATIC_ROOT = 'staticfiles' 
STATIC_URL = '/static/' 

STATICFILES_DIRS = (
    os.path.join(BASE_DIR, 'static'), 
) 

MEDIA_URL = STATIC_URL + "media/" 
MEDIA_ROOT = os.path.join(PROJECT_ROOT, *MEDIA_URL.strip("/").split("/")) 
ROOT_URLCONF = "%s.urls" % PROJECT_APP 
TEMPLATE_DIRS = (os.path.join(PROJECT_ROOT, "templates"),) 

gli URL .py è come questo:

from __future__ import unicode_literals 
from django.conf.urls import patterns, include, url 
from django.conf.urls.i18n import i18n_patterns 
from django.contrib import admin 
from mezzanine.core.views import direct_to_template 
from mezzanine.conf import settings 
from views import contato 

admin.autodiscover() 

urlpatterns = i18n_patterns("", 
         ("^admin/", include(admin.site.urls)), 
         ) 

if settings.USE_MODELTRANSLATION: 
    urlpatterns += patterns('', 
         url('^i18n/$', 'django.views.i18n.set_language', name='set_language'), 
         ) 

urlpatterns += patterns('', 
        url("^$", direct_to_template, {"template": "index.html"}, name="home"), 
        url(r'^contato/$', contato, name='contato'), 
        ("^", include("mezzanine.urls")), 
        ) 

handler404 = "mezzanine.core.views.page_not_found" 
handler500 = "mezzanine.core.views.server_error"

come potete immaginare, quando imposto DEBUG = True funziona correttamente, ma poiché voglio testare l'ambiente di produzione ho bisogno di usare DEBUG = False. Cosa sto facendo di sbagliato?

Answer 1

Non dovrebbe essere necessario eseguire collectstatic ogni volta che si avvia il banco web. Qual è l'output di heroku run python manage.py collectstatic --noinput?

Guardando attraverso the heroku docs, non è chiaro se si è eseguito questo passaggio:

Django non creerà automaticamente la directory di destinazione che utilizza collectstatic, quindi si consiglia di aggiungere un file fittizio al repository, come visto qui

Answer 2

La configurazione del file statico è danneggiata. STATIC_ROOT deve essere un percorso assoluto come /some/absolute/path/. L'impostazione TEMPLATE_DIRS non è aggiornata, supponendo che tu sia su Django 1.8, puoi usare invece il TEMPLATE. L'opzione APP_DIRS fa in modo che django cerchi le directory dei modelli in tutte le directory dell'applicazione installate. È possibile aggiungere ulteriori elenchi come elenco utilizzando l'opzione DIR.

Questo è come il settings.py dovrebbe probabilmente essere simile (avrei bisogno i vostri progetti di layout dir per essere sicuri):

ALLOWED_HOSTS = ['*'] 
DEBUG = False 
PROJECT_APP_PATH = os.path.dirname(os.path.abspath(__file__)) 
PROJECT_APP = os.path.basename(PROJECT_APP_PATH) 
BASE_DIR = os.path.dirname(PROJECT_APP_PATH) 
CACHE_MIDDLEWARE_KEY_PREFIX = PROJECT_APP 
STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage' 
# This is the path where Django will store the collected files 
STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') 
STATIC_URL = '/static/' 
# STATICFILES_DIRS must contain the absolut path to your static resources 
STATICFILES_DIRS = (
    os.path.join(BASE_DIR, 'static'), 
    # add more paths with static files here 
) 

MEDIA_URL = STATIC_URL + "media/" 
MEDIA_ROOT = os.path.join(BASE_DIR, *MEDIA_URL.strip("/").split("/")) 
ROOT_URLCONF = "%s.urls" % PROJECT_APP 

TEMPLATES = [{ 
    'BACKEND': 'django.template.backends.django.DjangoTemplates', 
    'APP_DIRS': True, 
    # Additional directories to look for templates 
    'DIRS': [some_template_directory,], 
}] 

Con questa collezione di configurazione e al servizio di file statici dovrebbe lavoro.Se non funziona, fornire ulteriori informazioni sulla struttura della directory Progetti e l'output del comando heruko run manage.py collectstatic --noinput, come richiesto nell'altra risposta.

Ultimo ma non meno importante, la tua applicazione di debug non dovrebbe mai essere mai accessibile da internet. Le persone con intenti malevoli possono apprendere molto sulla configurazione dai messaggi di debug.
