Help w/ pulling data from 2 tables and displaying the results

Hello,

I'm brand new to ruby and I'm having trouble pulling data from one
table (table_1), looping through the results and pulling data from
another table (table_2) and displaying the results of table_2 in one
field.

the pseudo code would be as follows:

Code:

result_1 = select first_name from table_1
loop results_1 
{
      puts "<tr><td> results_1.first_name<td>" 

      results_2 = select table_2.info from table_2 where table_1.user_id = table_2.user_id; 
        puts "<td>"
        loop results_2 
        { 
             puts "<li>table_2.info 
        } 
        puts "</td>" 
}

The display would look like this for 1 row:

joe | -info 1
-info 2
-info 3

Help - I'm desparate!

Umm, you could revise your select statement to this:

Code:

select table1.first_name, table_2.info from table_2 where table_1.user_id = table_2.user_id;

This way, you need only one loop and the data is in the tabular format you need.

Problem solved!

Ok - I finally buckled down and asked a couple of questions and there
was a method in the accounts model that was killing this whole concept:
Problem solved!

The project I'm building a little addition to is huge and extremely complex so there's a lot of code that could overide or clash w/ code I'm trying to develop.

That was the case here. In the Account model there was this method that was overiding my join attempts.

def spaces
spaces = Space.find :all, :conditions => ['owner_id = ?',
self.user_id]
end

Now, once I got rid of that method - this works perfectly!
@accounts = Account.find(:all, :include => :spaces, :limit => 20)

I got dumped right into the fire w/ this new project - it pays to ask a few simple questions. I tore a lot of hair out trying to figure it out, but also learned a great deal trying to find the answer.

posts!

Cheers!
