title: PyCharm - Unresolved library 'staticfiles'
body: <p>I'm working on a Django project with PyCharm. Unfortunately PyCharm does not resolve the template tags I would like to use in my templates. </p>
  
  <pre><code>{% load staticfiles %}
  </code></pre>
  
  <p>The project is running within an Ubuntu VM via vagrant. The run configuration knows about the virtualenv I am using in the VM (remote interpreter setup).</p>
  
  <p>My settings look like this:</p>
  
  <pre><code>INSTALLED_APPS = [
      'django.contrib.admin',
      'django.contrib.auth',
      'django.contrib.contenttypes',
      'django.contrib.humanize',
      'django.contrib.sessions',
      'django.contrib.messages',
      'django.contrib.staticfiles',
      'django.contrib.sites',
      'django.contrib.flatpages',
      'django_extensions']
  
  INSTALLED_APPS += get_core_apps(['myapp.dashboard')
  
  STATICFILES_FINDERS = (
      'compressor.finders.CompressorFinder',
      'django.contrib.staticfiles.finders.FileSystemFinder',
      'django.contrib.staticfiles.finders.AppDirectoriesFinder',
      'compressor.finders.CompressorFinder',
  )
  
  STATIC_URL = '/static/'
  
  BASE_DIR = os.path.dirname(os.path.abspath(__file__))
  
  STATICFILES_DIRS = (
      os.path.join(BASE_DIR, '../../../../myfolder/static'),
  )
  </code></pre>
  
  <p>Still I get the warning <code>Unresolved library 'staticfiles'</code>. It shows the same behavior other template tags as well.
  Could the dynamic creation of the <code>STATICFILES_DIRS</code> be the issue? How could I solve this?</p>
