"#{@user.user_name} commented on #{@inquest.title.truncate(10)}"

 end
 def URL
    inquest_path(Inquest.find(params[:comment][:inquest_id]))
 end

Answer 1

The issue is you have dependent: :destroy in your association:

class Inquest < ApplicationRecord
  belongs_to :user, dependent: :destroy
end

which deletes the user with Inquest so the account is deleted. A User can have many Inquest and there are many related associations usually with User so destroying it with other objects is a bad idea. Instead, the User model should have dependent: :destroy with the associations in general cases.
