Hi All,
We've been using TT2 for our ecommerce application for the last couple of
years. Until recently we were running version 2.14 and have just upgraded to
the latest version (2.19). We checked the changes log for any gotcha's and
since there didn't seem to be any, we proceeded with the upgrade.
The problem we have now is with the template treating single element arrays
as scalar object. For example we use the following to display the first of a
products images:
[% product.images.first.filename %]
Is that a list of objects or hashes? If so I suggest you downgrade to 2.15
until the next release, I've a patch in (hopefully!) that fixes it.
which should give us the filename of the first image in the product.images
array. Until the recent upgrade this did work for all instances, but now, if
we have a product that only has one image, the template is treating it as a
scalar object, so 'first' returns an empty object and no value gets displayed
in the template.
Is this a known issue, and if so is there a fix? I realise we could do
something like:
[% IF product.images.size > 1 %]
[% product.images.first.filename %]
[% ELSE %]
[% product.images.filename %]
[% END %]
Kinda hard to do .size on something that isnt a list, and if your one-item
is an object/hashref you'll get the number of keys, which probably isnt
what you meant..
however, the application we have is installed on many different sites on
several different servers, so making a change like this would not be trivial.
Any help from the list would be much appreciated.
Don't upgrade til 2.20..
I suggest next time you watch the RT bug list as well as the Changes file.
