that does work in my console window, but it does not return anything in the controller.
e.g. if i say email=params[:user][:email], and then used it like this: User.find(:first, :conditions => "email = email"), it does not return anything. The only way it works if I hardcode that email in the query.

User.find( :first, :conditions = [ 'email = ?', email ])
or
User.find( :first, :conditions = { :email => email } )
In both cases, the last "email" in the state is a variable for the e-mail address you want.
For both of these constructs: Review AWDR!! The first is about using parameters for a SQL query. The 2nd is about using a Hash for the conditions. I like the latter for simple finds.

Will there be a solution posted for project 3?
Also I am having problem with this. I have a table - users, which has email column. Now i want to enable all users to search the user table with the query 'email'.
<%= form_tag( { :action => :find, }, { :method => :post }) %>
<%= text_field "user", "email", "size" => 20 %>
Search with the email
<%= submit_tag( "Search" ) %>
Well, the controller that handles is 'search' controller.
I have tried getting the email and print it out on the screen, but it always prints nil. How do I get this attribute?

How are you trying to access the email field? params[:user][:email] should work.

I cannot find the rest of the assignment 3? Where is the instructions for that? I've downloaded the zip with migration one, but the doc-file is empty of instructions.

That download shows only the mgrations and associations for the first milestone -- it is, effectively, the "solution" for the first (optional) milestone -- I am still working on getting the list of "finds" for milestone II and the final version of Assignment 3 to you.

I am having trouble watching 5th lecture. I have tried on three different dsl services. The latest one is about 1Mbps. Somehow, it keeps breaking. I do not have issues with the other lectures so far.

I have asked Harvard to review the video.

Our contact at Harvard says that they don't see any problem, and asks: "Is he trying the flash or real player? I would tell them to hit the "report a problem" button and someone will help them work through the issue."

The demo won't work until you finish the assignment -- i.e., demo is for "final checkout."
I am planning to do a screencast that will show you what the demo will look like when you're done.

"syntax error, unexpected $end, expecting kEND"
Look at your code and verify that all blocks are ended correctly.

My password is somehow not getting accepted. What should I do?

You shouldn't be using your personal password. You should be using the common password for this page, that was announced in the first lecture.
That password is still working, as of a few minutes ago.
But some time in the next few days, the password to this page will change to a new user/password combination that John announced in last night's lecture (October 1).

How did you install Rails? Can you find the rails command on your disk?
