Hello 👋 It's not really an issue directly with Solidus, I added to my solidus project the gem ahoy (https://github.com/ankane/ahoy) for server-side Analytics but I get an error when I try to login in with an User

NameError in Spree::UserSessionsController#create

Rails couldn't find a valid model for User association. Please provide the :class_name option on the association declaration. If :class_name is already provided, make sure it's an ActiveRecord::Base subclass.

There is not

Ahoy::Visit::User

I guess the controller is looking for

Spree::User

? The issue : https://github.com/ankane/ahoy/issues/513

Did you already configure the

current_user

method to match the one used by solidus?

Ahoy.user_method = :spree_current_user

I added

Ahoy.user_method = :spree_current_user

into

initializers/ahoy.rb

but still the same error

class Ahoy::Store < Ahoy::DatabaseStore
end

# set to true for JavaScript tracking
Ahoy.api = false

# set to true for geocoding (and add the geocoder gem to your Gemfile)
# we recommend configuring local geocoding as well
# see <https://github.com/ankane/ahoy#geocoding>
Ahoy.geocode = false


Ahoy.user_method = :spree_current_user

peeking through Ahoy’s code it seems like the generator will setup an active record Ahoy::Visit model for you, if you open app/models/ahoy/visit.rb you should see something like:

class Ahoy::Visit < ApplicationRecord
  self.table_name = "ahoy_visits"

  has_many :events, class_name: "Ahoy::Event"
  belongs_to :user, optional: true
end

If that’s the case you should adjust the

belongs_to

association to point toward

Spree::User

instead of a generic

User

, adding

class_name: 'Spree::User'

should be enough

Ok ! It's working Thank you @elia :)
