Output only the first or a particular record using TAL
Hi all, I wanted to create something of a header using TAL and a Z SQL Method. I have the following code where getCustomerLicenses is my Z SQL Method and it prints out the customer's full name with details: <tr tal:repeat="licenses container/getCustomerLicences"> <td><span tal:replace="licenses/full_name">full_name</span></td> <td><span tal:replace="licenses/serial_number">serial_number</span></td> <!-- code continues with more details --> </tr> In it's simplest form, how do I retrieve just the full_name of the first record using TAL. I think I use tal:replace but I'm not sure. I was along the lines of something like this: <tr tal:define="x container/getCustomerLicences"> <td tal:replace="x/full_name[0]></td> </tr> But then I just get a TypeError. I guess if I get this working, I can start playing around with conditions but I'm stuck! Thanks, Julian Yap

you can't mix "path expressions" and "python expressions". try something like <td tal:replace="python: x.full_name[0]></td> Cheers, Sascha

You need to access the first record before asking for its attributes. Also, path expressions don't play nicely with integer indexes, so you need to use Python: <td tal:content="python: x[0]['full_name']" /> You can use 'tal:condition repeat/licenses/start' to test that you are in the first pass through the loop.
