Did anyone implement the compare function for the extra credit?

This sounds like a plan.

Having been laid off mid last week, a new adventure begins. I want to use this time to retool.

The calculus I am trying to solve is how long it will take for me to become employable in RoR. It seems to me, 6 to 18 months.

John, can we talk about employment with RoR?

Thank you for the sympathetic ear. The thing I was missing was the 1:n relation between measurements and units.

I was using the equivalent of x[0].units.id rather than x[0].units.first.id .

Having to explain the problem helps clarify the issues in my own head.

I am still curious about the sql code view though.

I am running system/console in C:\aaa\rubyStuff2\e168-assignment3-milestone-3-30000

I am having trouble writing a sql select to get units.id given observation_kinds.id. Here is the ActiveRecord code that I am using.

>> X = Measurement.find(:all, :conditions => "observation_kinds.id = 6", :include => [:observation_kinds, :units])

X appears to be an Array but I am having difficulty navigating X. What little bit that I can see does not include units.
Second, I would really like to see the sql code used to get whatever is in X.
Setup.rb from a previous assignment (I assume for use without Rails; just ActiveRecord with ruby) does not provide me sufficient clues to see the sql.
Given the number of hours I have spent on this, I am ready for some hints.
Thanks
Brian

Might it be possible to get MilestoneII? It would be nice to get the jump on it while I have some extra cycles.
Thanks

I think I just had an epiphany.

On block parameters, for Enumerable#inject there is |memo, obj| . From the context of what you are saying above, is it possible to get memo1, memo2 ... ? I can force it with array of arrays etc but it would be nice to short circuit this with user created block parameters. Is this possible?

Also I am not seeing the lecture 2 notes. In fact, I am not seeing anything to download on the downloads page.

Where is the Assignment1 zip file? I am not seeing a link to the right of the Assignment 1 bullet. I do not see it on the downloads page and I do not see it on the Assignment 1 page. I am going in circles
