Hi Rob,
So I tried what you suggested.
Here’s the new code: http://pastie.org/392399
And here’s the new error: http://pastie.org/392397
Some comments.
First the line
url_hash = {}
is useless. I get the impression that you are coming from some
statically
typed language and think of this as a declaration of the type of the
variable url_hash. Ruby doesn’t have typed variables, and neither has a
mechanism for or a need for declaring types.
Ok, that said,if you inspect what the next line is actually returning:
url_hash = istock_data.to_hash
p url_hash
You should see something like:

{}, {}, {}, {}, {}, {}, {}]
Which is an array of hashes. The fetch call is looking for a string
containing the url to be fetched.
So, instead you need to take another approach, and
- extract the url from each hash,
- Scrape each individual url, and collect the results.
Something like:
http://pastie.org/392796
This doesn’t work because the urls are relative, and I don’t have the
time
or motivation to figure that out for you, but this should get you
another
step along the way.
