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> </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==''"> </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
