Not exactly... I define something called 'image' and display it using the following code. <span tal:define="image string:${here/id}.jpg"> <img tal:attributes="src image" /> </span> "id" being the id of my ZPT, with a .jpg extension to display an image which shares the same id as a ZPT but with a .jpg extension. But what I want to test is if the 'image' object does not exist within the ZODB ... and display a "no image", image. <span tal:condition="not:python:here.objectIds(image)"> no image </span> But the above doesn't work. -----Original Message----- From: Dragos Chirila [mailto:d.chirila@finsiel.ro] Sent: Tuesday, 20 July 2004 5:58 PM To: zope@zope.org; Michael Fox Subject: Re: [Zope] ZPT Help! If I understand corectly, you can have zpts without a coressponding image, but you cannot have an image without a corresponding zpt. If so, here is the piece of code that does the job: <tal:block repeat="item python:here.objectValues('Image')"> <tal:block define="zpt python:here[item.getId().replace('.jpg', '')]"> Page Template: <span tal:replace="structure zpt"/><br> Image: <span tal:replace="structure item"/> </tal:block> </tal:block> So, iterate over all images in the folder. Extract the name of the zpt by removing the '.jpg' extension from the image id. Display the content of the zpt and then the image. Hope this will help, Dragos Michael Fox wrote:
Hi *,
I have a folder which contains a bunch of ZPT's and images, some of which share the same unique ID as a ZPT which a ".jpg" extension. ie.
1000 1000.jpg 1001 1002 1003 1004.jpg 1004
I have an index_html object which will render any ZPT in this directory and the matching image, if available.
If there is no matching image I want to display an "image unavailable", but can't get this to work.
<span tal:define="image string:${here/id}.jpg">
<span tal:replace="image"></span>
<span tal:condition="not:python:here.objectIds(image)"> There are currently no items available. </span>
</span>
