Rails 3 mailer for a model without an email attribute

Question

I want to create a PageMailer which emails users when someone interacts with one of their pages.

The User has_many pages, and so the page email is defined as user.email

I have tried attr_reader in the Page model, and also I've declared an email method, neither are currently working

I'm getting an error message which states: undefined method 'email' for <Page:0x512000d4>

Can anyone suggest a simple workaround?

thanks

Hard to say without any code! Personally I would be passing both the user and the page objects to the mailer. — Frederick Cheung, Dec 20 '11 at 16:30
Hi Frederick, I tried that and it complains that I'm passing the wrong number of arguments (2 for 1) — Paul Nelligan, Dec 20 '11 at 16:35
obviously you'd need to setup the mailer to accept 2 arguments, but without seeing what you're doing I'm just guessing — Frederick Cheung, Dec 20 '11 at 16:36
that's what I've done ... please ref. http://pastebin.com/XFiaJT4q — Paul Nelligan, Dec 20 '11 at 16:42
That looks like it should work. What errors are you getting (note that you need to restart delayed_job for it to pick up changes - it might be simpler to not use delayed job until you've got things working) — Frederick Cheung, Dec 20 '11 at 16:56

send_fb_like_email(user, page)
undefined method 'email' for <Page:0x512000d4>

The error says it's trying to find the "email" of a "page". Looks like you've accidentally switched the user and page params in one of the calls to the method. Go check all the places where you call this email method and see if you've done that.

Hi Taryn, that's not actually the case ... I had previously tried a 'page_mailer' with just one param - a page object ... It was telling me that email was not a method of Page, when it clearly was! – Paul Nelligan Dec 20 '11 at 17:45
is it a method of Page (the class) or of *a* page (ie an instance of Page) ? – Taryn East Dec 20 '11 at 17:50
Also - please note, I can only comment based on the code that you actually show us... and the code that you have actually showed us show that it's trying to access email from a user object, not a page object, and that the error is that it's trying to access email form a page object. – Taryn East Dec 20 '11 at 17:52
