Tutorial: 5.7 Showing Posts #2

I figured I would post this in hopes of preventing other people from wanting to strangle their computers (because that's possible, didn't you know?).

As I was going through the tutorial, I reached section 5.7, where I quickly became confused. Here's where I mean: 5 7 showing posts

I googled for a few minutes and came up with a more concise version of the section, here: http://edgeguides.rubyonrails.org/getting_started.html#showing-posts.

What was holding me up was that I didn't know what "post GET /posts/:id(.:format) posts#show" was, if I was supposed to put it somewhere, or if so, where I was supposed to put it. But it turns out, it's just what you're supposed to see when you run the command "rake routes." So if you see that, then everything's working right.

That just means that when you send a GET request (access the page with your browser) to /posts/:post_id (with optional format specifier it looks like), that means run the PostsController's show action with the post that the id points to. That's pretty standard syntax for a route in an MVC framework. I use Zend Framework for PHP and it looks almost identical.

Thank you for the clarification on that :) I mean, while I was doing it, I knew basically what I was looking at, but the tutorial was very unclear on what I was supposed to be doing with that particular line. It doesn't tell you in the tutorial at all, so it was confusing. I got it figured out eventually though haha

Sounds like we've got it resolved, and other students will be able to search the issues for this problem. Nice work!
