can't write unknown attribute sash_id when calling points method on user

[iamdriz]

When calling: @user.points to show the points for the current user we get the error:

can't write unknown attribute `sash_id`

From the console I see the following:

ActionView::Template::Error (can't write unknown attribute `sash_id`):
    10: 
    11: <h2>Recent posts (<%= @user.forum_posts.count %>)</h2>
    12: 
    13: <%= @user.points %>

I've checked the database (SQLite in development) and all the tables look fine. Any ideas what's the cause?

Rails 6.0.3.2
Merit 4.0.0
Ruby 2.5.7

So this was caused because this migration wasn't generated:
https://github.com/merit-gem/merit/blob/master/lib/merit/generators/active_record/templates/add_merit_fields_to_model.erb

I manually created the migration and now it's working.

Thanks for reporting. I need to fix it as part of #351
