I have installed everything, but when I type rails test or rails assn0, I get an error that there is no inernal command as rails. My ruby script/server is not running either.

I got the problem fixed. I reinstalled ruby on windows, and somehow it worked the second time.

John,

Could there be screenshots or codes which you show in demos be in the slides as well? I sometimes have to watch in low resolution, and it becomes hard to make sense in the video window.

I've lookded into that. Apparently all blocks are ended fine and I tried changing the location of solution to the 'other' folder, but the same error.

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 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.

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?

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.
