Gem seems to ignore model with non-standard id column

[rhulse]

Description

The meilisearch-rails gem fails to properly handle Rails models that use a custom primary key column (other than id). The gem creates a Meilisearch index with "id" as the primary key regardless of the Rails model's actual primary key configuration, causing search results to fail when mapping back to ActiveRecord objects.

# Rails correctly identifies the primary key
Story.primary_key
# => "story_id"

# But Meilisearch uses "id" regardless
MeiliSearch::Rails.client.index("Story").get_primary_key
# => "id"

Expected behavior

The Model.search returns a set of results
There are items in the min-console to search

Current behavior

I get an empty set => []
There is nothing in the mini-console

Note

If I don't set :primary_key on the config block, then I do get items in the min-console, but Story.search still returns nothing.

Environment

Operating System
OSX 15.6.1 (24G90)

Meilisearch version (./meilisearch --version):
V 1.19.1

meilisearch-rails version (bundle info meilisearch-rails):
0.16

rails version (bundle info rails):
8.0.2.1

Reproduction script:

Create a Rails model with a custom primary key:

rubyclass Story < ApplicationRecord
  include MeiliSearch::Rails
  
  self.primary_key = 'story_id'  # Custom primary key column
  
  meilisearch primary_key: :story_id do
    # configuration
  end
end

Index some data:

rubyStory.reindex!

Attempt to search:

rubyStory.search('test query', limit: 10)

I found the cause. I'll work on the fix ;)
