Searchkick: Cannot define custom mappings

[namila]

Hi,
Below is my setup

searchkick 4.0.0
rails 5.1.7
ruby 2.6.2
ElasticSearch 7.0.1
MacOS 10.14.4

I am trying to define a custom mapping for a field since I need it to be indexed as a float

searchkick word_middle: %i[name product_id category_ids updated_at retail_price retail_price_for_sorting origin_id company_group_id product_group_ids], mappings: { product: { properties: { retail_price_for_sorting: { type: "float"}, } } }, merge_mappings: true

and once I try to reindex I get the following error

Elasticsearch::Transport::Transport::Errors::BadRequest ([400] {"error":{"root_cause":[{"type":"mapper_parsing_exception","reason":"Root mapping definition has unsupported parameters: [product : {properties={retail_price_for_sorting={type=float}}}]"}],"type":"mapper_parsing_exception","reason":"Failed to parse mapping [_doc]: Root mapping definition has unsupported parameters: [product : {properties={retail_price_for_sorting={type=float}}}]","caused_by":{"type":"mapper_parsing_exception","reason":"Root mapping definition has unsupported parameters: [product : {properties={retail_price_for_sorting={type=float}}}]"}},"status":400})

any thoughts on this?

Thanks in advance :)

This issue does not occur with ElasticSearch 6.2.2. But present in ElasticSearch 7.0.1

Hey @namila, Elasticsearch 7 does not support mapping types. You'll need to remove the root product key.

ES 6

class Product < ApplicationRecord
  searchkick mappings: {
    product: {
      properties: {
        name: {type: "keyword"}
      }
    }
  }
end

ES 7

class Product < ApplicationRecord
  searchkick mappings: {
    properties: {
      name: {type: "keyword"}
    }
  }
end

Thanks a lot @ankane :) by the way this is an awesome Gem <3

Made root type mapping optional on master with Elasticsearch 6, so the Elasticsearch 7 example above can be used for both versions going forward.
