Hello all,

I am a newbie at Zope, slowly traversing the learning curve.  I am focusing on TAL currently, and am quite a bit confused with the tal:condition syntax.  I have a Z SQL Method that selects all records from a table in a PostgreSQL database.  This method is called "getTransfers".  I then have a Page Template called "displayTransfers" that displays the results as tabular HTML.

This works fine.  However, where there isn't a record (i.e. an empty string), a <TD> will not be defined so that it leaves ugly gaps in the table.  To ensure that a '<TD>&nbsp;</TD>' replaces an empty string '' I added two tal:condition statements.  This works, but is sort of ugly looking as, in my head, it is the equivalent of two 'if' statements when it should be an 'if/else'.  The below code works, however is there a cleaner way to do this?

### START CODE ###

<table border="1">
  <tr><th>Date</th><th>Server</th></tr>
  <tr tal:repeat="transfer container/getTransfers">
    <td tal:content="structure transfer/time_stamp">time_stamp</td>
    <td tal:condition="python: transfer.server==''">&nbsp;</td>
    <td tal:condition="python: transfer.server!=''"
        tal:content="structure transfer/server">server</td>
  </tr>
</table>

### END CODE ###

I'm from a PHP/Perl/mySQL/postgreSQL background and am new to OOP, Python and Zope so I greatly appreciate any assistance with this.

Regards,
Tom
