    <p>I'm trying to export a CSV file of Newbie user email addresses. Newbies are users "created_at" after the date selected in the date_select tag (basically the most recent sign-ups). </p> <p>I'm using the FasterCSV gem and <a href="http://synthesis.sbecker.net/articles/2007/06/07/how-to-generate-csv-files-in-rails" rel="nofollow">Scott Becker's code</a>, and borrowed the @start_date from <a href="http://snippets.dzone.com/posts/show/4630" rel="nofollow">here</a> to implement in the method.</p> <p>Here's what my controller looks like:</p> <pre><code> def newbs_export @start_date = Date.civil(params[:range][:"start_date(1i)"].to_i, params[:range][:"start_date(2i)"].to_i, params[:range][:"start_date(3i)"].to_i) @users = User.find(:all, :if =&gt; [@created_at &gt;= @start_date]) csv_string = FasterCSV.generate do |csv| # header row csv &lt;&lt; ["email"] # data rows @users.each do |user| #if user[:created_at] &gt;= Time.now csv &lt;&lt; [user.email] end end # send it to the browsah send_data csv_string, :type =&gt; 'text/csv; charset=iso-8859-1; header=present', :disposition =&gt; "attachment; filename=newbs.csv" end </code></pre> <p>Here's my newbs.html.erb:</p> <pre><code>&lt;% form_tag({:controller =&gt; "accounts", :action =&gt; "newbs_export"}, :method =&gt; "get") do %&gt; &lt;%= date_select('range', 'start_date', :order =&gt; [:month, :day, :year])%&gt; &lt;%= submit_tag("Submit") %&gt; &lt;% end %&gt; </code></pre> <p>I've mixed code and dug myself a bit of a hole trying to stitch different solutions together. Any advice on where I could go from here?</p> <p>Thanks!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
