I do apologize for that, I am quite new to the mailing list format of communication (which is even harder to grasp while viewing the discussion on a site called "ruby-forum"). >> >> comment.user.email yields the commenters email, etc. However when >> passing comment.user into anything now fails. >> >> NoMethodError in Snippets#show >> >> Showing >> /Users/morri534/rails_projects/srclockr/app/views/comments/_comment.html.erb >> where line #2 raised: >> >> undefined method `email' for nil:NilClass > > You appear to have provided lots of irrelevant information this time, > but not shown the code where the error is generated.

This is true, I'm having a very hard time conveying this issue. I have spent countless hours trying to dig through debugging guides (including the one referenced by you) yet I haven't been able to ge to the bottom of this yet. As a direhard PHP programmer, getting my mind into Rails mode is proving to be a challenge, even after reading a whole book and a number of web resources on the topic. So maybe this will help. If anyone is still willing to take a peek, I have put the code on Github. The comment form partial that was in place when the comment listings was working is this: https://github.com/uberamd/srclockr/blob/93c88fd17bb4ddde6c9a0eb88a87b2cfeefde897/app/views/shared/_comment_form.html.erb When _comment_form.html.erb looked like that I was able to get comments to display properly using this code: https://github.com/uberamd/srclockr/blob/93c88fd17bb4ddde6c9a0eb88a87b2cfeefde897/app/views/comments/_comment.html.erb However, when I changed _comment_form.html.erb to this code, the ability to comment started working perfectly, however listing comments stopped working: https://github.com/uberamd/srclockr/blob/master/app/views/shared/_comment_form.html.erb Whats odd (to me) is that I can call comment.user.email and get the users email, but changing the _comment_form.html.erb file caused the displaying of comments to break, which is not associated. The comment, snippet, and user controller can be seen here: https://github.com/uberamd/srclockr/tree/master/app/controllers And the page where everything is brought together (snippets/show.html.erb): https://github.com/uberamd/srclockr/blob/master/app/views/snippets/show.html.erb Hopefully this helps clarify the error I'm seeing. Despite my attempts to debug, I'm just entirely lost as to why changing the partial for the comment form broke the displaying of comments, though I'm sure its a fairly basic error I'm encountering. Especially since, on the comments partial, I'm still able to see the comment.content, just none of the comment.user (who made the comment) information. 1 beer for anyone who can help guide this lost soul :) -Steve > > Also have a look at the Rails Guide on debugging, which will show you > techniques that can be used to help in debugging the code. > > Colin -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
