I have error in my app:
SQLite3::SQLException: DISTINCT aggregates must have exactly one argument: SELECT DISTINCT COUNT(DISTINCT ) FROM "impressions" WHERE "impressions"."impressionable_id" = ? AND "impressions"."impressionable_type" = ?.
What Can I do?
My model product.rb has:
is_impressionable :counter_cache => true, :column_name => :viewed_count, :uniq => true
My controller
class ProductsController < ApplicationController
impressionist actions: [:show]
def show
...
impressionist(@product, nil, { unique: [:session_hash]})
end
end
My view has:
= @product.impressionist_count(:filter=>:ip_address)
Do you use squeel which causes similar issue in impressionist ? Please check your gem versions to be up to date.
