I have the ability to send email to a user if a certain user has requested interest in their product. In my email I want to include certain information that is pulled from users but at the moment I am getting errors because it states that they are undefined despite these lines being used elsewhere in my application. I shall copy the email below and anything between the <% %> is what I wish to include and was wondering if anyone could point me in the right direction and tell me which are those that are correct and are not. Any help would be wonderful. The message I want to send is as followed:
Hello <%@user.username%>
The user <% current_user.username %> has registered an interest in the following product of yours:
<% @book.book_name %> <% @book.genre %>
The user <% current_user.usernames %> has the following games for offer:
<% current_user.book.book_name %>
To view <% current_user.username %> profile click <% link_to "here", current_user.show %> If you wish to contact the user by email then contact the following email <% current_user.email %>.
I hope that makes sense. In order to give further insight in to what I have, I have a users table that includes user information and a book table that has books information with a user_id foreign key. Users have a has_many with books and games belongs_to user.
The @user lines work for me but I get undefined method for anything after @book e.g. undefined method 'book_name'. Why is this so when it works for user?
Finally I have come to understand that the mailer doesn't recognise current_user? how would I go about doing the current_user line if that line is not able to be used?
