There is no right solution by default. My way (or equivalent) is useful when @posts is (or can be) in fact a collection of elements and you want to do the same thing for every element. If you know for a fact that there is only one element in the @posts object, Conrad's solution above will suffice and maybe even be neater. You should then call it @post though.
Eric's solution is actually the same as mine, but it deduces the partial name from the object and repeats the partial's contents for each element. If that works for you (which didn't show from your first post) you can also use that. Hope this helps!
