KeyError Django where to dig?

Question

Django

Good afternoon.
When I try to start the test server (py manage.py runserver), I get the following error:
KeyError: 'ELASTIC_HOST'
And it refers to:

...line 147, in <module> 
'URL': ':'.join([ENV_DICT['ELASTIC_HOST'], str(ENV_DICT['ELASTIC_PORT'])]),

Actually the code itself:

HAYSTACK_CONNECTIONS = {
    'default': {
        'ENGINE': 'elasticstack.backends.ConfigurableElasticSearchEngine',
        'URL': ':'.join([ENV_DICT['ELASTIC_HOST'], str(ENV_DICT['ELASTIC_PORT'])]),
        'INDEX_NAME': 'aden',
    },
}

But everything works on the production server. Explain what's the matter?
PS python 3.6.6; django 1.11

Answer 1

ENV_DICT ='ЗНАЧЕНИЕ' ./manage.py runserver
apparently, you need to set an environment variable ... or disable elastic

Answer 2

Default config looks like this

HAYSTACK_CONNECTIONS = {
    'default': {
        'ENGINE': 'haystack.backends.solr_backend.SolrEngine',
        'URL': 'http://localhost:9001/solr/default',
        'TIMEOUT': 60 * 5,
        'INCLUDE_SPELLING': True,
        'BATCH_SIZE': 100,
        'EXCLUDED_INDEXES': ['thirdpartyapp.search_indexes.BarIndex'],
    },

most likely you forgot to import the file with settings variables, look in the last config if everything is imported
