Django和Heroku控制台中的静态文件出现404错误

Question

I am able to run collectstatic fine when I push to Heroku. The problem now is I that I'm not sure how to reference them when they're stored on the server.

For example for my stylesheets I get a 404 error: <link rel="stylesheet" type="text/css" href="/static/bower_components/bootstrap-material-design/dist/css/material.css" />

This is the URL in the console that is causing the 404: GET https://tixblast-membership.herokuapp.com/static/bower_components/bootstrap-material-design/dist/css/material.css net::ERR_ABORTED 404 (Not Found)

What part of my settings to I alter to make sure I look in the right place? I ran heroku run python manage.py findstatic --verbosity 2 css/styles.css to show where it was looking for static files and it returned: /app/.heroku/python/lib/python3.7/site-packages/django/contrib/admin/static /app/.heroku/python/lib/python3.7/site-packages/rest_framework/static

So do I need to include one of the above directories in my settings?

I assumed that after I got collectstatic working I'd be fine, here is my settings.py:

"""

My stylesheet:

file structure where my app is located, its in the same folder as my settings.py. Which is the only way heroku would notice it:

└───static ├───bower_components │ ├───angular │ ├───angular-cookies │ ├───angular-route │ ├───bootstrap │ │ ├───dist │ │ │ ├───css │ │ │ ├───fonts │ │ │ └───js │ │ ├───fonts │ │ ├───grunt │ │ ├───js │ │ ├───less │ │ │ └───mixins │ │ └───nuget │ ├───bootstrap-material-design │ │ ├───dist │ │ │ ├───css │ │ │ ├───fonts │ │ │ └───js │ │ ├───fonts │ │ ├───less │ │ ├───sass │ │ └───scripts │ ├───jquery │ │ ├───dist │ │ └───src │ │ ├───ajax │ │ │ └───var │ │ ├───attributes │ │ ├───core │ │ │ └───var │ │ ├───css │ │ │ └───var │ │ ├───data │ │ │ └───var │ │ ├───effects │ │ ├───event │ │ ├───exports │ │ ├───manipulation │ │ │ └───var │ │ ├───queue │ │ ├───sizzle │ │ │ └───dist │ │ ├───traversing │ │ │ └───var │ │ └───var │ ├───ngDialog │ │ ├───css │ │ └───js │ └───underscore ├───javascripts │ └───authentication │ ├───controllers │ │ └───New folder │ └───services └───lib └───snackbarjs

This is where django is looking for the templates according to the error screen:

Using engine django:

django.template.loaders.filesystem.Loader: /app/static/index.html (Source does not exist)
django.template.loaders.app_directories.Loader: /app/.heroku/python/lib/python3.7/site-packages/django/contrib/admin/templates/index.html (Source does not exist)

Answer 1

Going off what works for me, try deleting STATICFILES_FINDERS setting. I don't think this is necessary for serving static with whitenoise. In any case I don't use it. Also, instead of MIDDLEWARE_CLASSES I just have MIDDLEWARE. Other than those minor changes I would just say try running your app with Debug=False on your local server and see if you run into problems.

Try changing your BASE_DIR setting to:

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

Answer 2

You should not hardcode static files URLs in your template when using static-files Django app instead, try the following in order to set up the static-files properly.

• Make sure that django.contrib.staticfiles is included in your INSTALLED_APPS.

• In your settings file, define STATIC_URL

example:

STATIC_URL = '/static/'

In your templates, use the static template tag to build the URL for the given relative path using the configured STATICFILES_STORAGE :

{% load static %}
<img src="{% static "my_app/example.jpg" %}" alt="My image">

I fixed it, I added the NodeJS buildback to Heroku. That installed the bower_components in the right folder. I'm using Python and Angular so I had the buildpack for the former but not the latter.
