Question

I have a Rails blog coming along quite nicely. However, I cannot seem to get my tagged articles to show up within their own page (for example, I’d like ONLY the articles tagged Arts & Entertainment to show up when that link is clicked).

I have a column in my scaffold model entitled tags. It takes a string. So

1) How do I go about accessing ONLY a specific tag? I tried something like the following:

def self.sports
    find(:all, :tags => 'gainmuscle')
end

to no avail.

2) How do I get them to show up in the view?

Any help would be very much appreciated.

You can probably define a method inside your controller something similar to this :

def self.tagged_with
  @articles = Article.tagged(params[:tag]).paginate(default_paginate_options)
end

Here tagged is a namedscope. you can neglect that but the action generates all the articles which are tagged with the tag selected as :param. Tag is an attribute of the model Article in this case.
