title: PyCharm does not resolve templates nor template tags nor statics in Django project
body: <p>PyCharm does not find templates, nor template tags, nor static files in my Django project even though the project itself is set up right and working. </p>
  
  <p>I am using Django <code>1.6.2</code> with this layout:</p>
  
  <pre><code>proj
    .devtmp
    manage.py
    proj
      settings.py
      app1
        templatetags
    app2
      templates
      static
  </code></pre>
  
  <p>and with settings like these:</p>
  
  <pre><code>from os.path import join, dirname, pardir, abspath
  
  PROJECT_ROOT = abspath(join(dirname(__file__), pardir))
  DEV_TMP_DIR = join(PROJECT_ROOT, pardir, '.devtmp')
  
  TEMPLATE_LOADERS = (
      'django.template.loaders.filesystem.Loader',
      'django.template.loaders.app_directories.Loader',
  )
  
  TEMPLATE_DIRS = (
      join(PROJECT_ROOT, 'templates'),
  )
  
  MEDIA_ROOT = join(DEV_TMP_DIR, 'media')
  MEDIA_URL = '/media/'
  
  STATIC_ROOT = join(DEV_TMP_DIR, 'static')
  STATIC_URL = '/static/'
  
  INSTALLED_APPS = (
      ...
      'django.contrib.staticfiles',
      ...
      'proj'
      'proj.app1'
      'app2'
  )
  </code></pre>
  
  <p><strong>Update:</strong></p>
  
  <p>In the IDE preferences, I have configured paths to the project root, <strong><code>settings.py</code></strong> and <strong><code>manage.py</code></strong>. In addition, I have configured the project interpreter (I am running the runserver from the IDE right now with no problems).</p>
