How to Original exception text was: 'Hit' object has no attribute 'id

[AlviseSembenico]

Hi, I'm currently facing the issue of not being able to retrieve the Id of a document properly. This is my code `class NewsDocument(Document):

column1 = fields.IntegerField()
meta_data_shareaholic_keywords = fields.TextField()
keywords = fields.TextField()

timestamp = fields.DateField()

class Index:
    name = 'news'
    settings = {'number_of_shards': 1,
                'number_of_replicas': 0}

class Django:
    model = NewsArticle
    fields = [
        'id',
        'title',
        'text',
        'summary',
        'url'
    ]`

`class NewsArticle(models.Model):

title = models.TextField()
text = models.TextField()
summary = models.TextField()
url = models.URLField()
column = models.IntegerField()
meta_data_shareaholic_keywords = models.TextField()
keywords = models.TextField()`

A sample of the data in the ES { "_index" : "neews", "_type" : "_doc", "_id" : "3DyhvHEBvFehRasu8OXt", "_version" : 1, "_seq_no" : 311, "_primary_term" : 1, "found" : true, "_source" : { "column1" : 311, "summary" : "", "keywords" : "", "title" : "Cards for electric car", "url" : "https://nltimes.nlt", "@timestamp" : "2019-12-12T01:00:00.000+01:00", "categories" : "['technology']", "text" : "Card holders can also check with most providers where and when their cards were used.", "publish_date" : "2019-12-12" } }

The serializer field might be named incorrectly and not match any attribute or key on the Hit instance. Original exception text was: 'Hit' object has no attribute 'id'.`

I have really no idea how to tackle this since my code is so minimal. Thank you for the support!

I think you should define id field in your document explicitly, like here.

Thanks @barseghyanartur, I tried but same outcome.

@AlviseSembenico:

Two steps:

• Step 1: Add id field to your document. Check the link in the example posted below. id = fields.IntegerField(attr='id')
• Step 2: Run re-index.
