i thought i sort of understood acquisition but this one has me stumped. /locations/index_html contains this : <dtml-var standard_html_header> <dtml-var mtdBanner> <dtml-var mtdCategoryListing> <dtml-var standard_html_footer> where mtdCategoryListing is a dtml method which formats the output from a z sql method. the z sql method takes one argument "category". now, if i run this with "/locations/index_html?category=hotels" it works fine. but i don't like ever using those "?var=value&var2=value2" urls. it would be better to use "/locations/hotels" for the example above. taking this one step further, to subcategories, "/locations/hotels/3star" would be way better than "/locations/index_html?category=hotels&subcategory=3star" ok, so far ? so, to enable this, i created another folder "/locations/Hotels" and this folder has a property called "category" whose value is "hotels" now, if i type in the URL "/locations/Hotels" there is no index_html in the folder, so zope then goes up one directory to "/locations" and uses "/locations/index_html" and then several things go wrong : a) the sql method called in mtdCategoryListing claims that there is no property called 'category'. how come it didn't pick it up from the subfolder Hotels which was in the URL ? b) worse, the dmtl method 'mtdBanner' in the index_html (see above) now bums out badly. it is actually in the root folder (ie. it is "/mtdBanner") and it's code is simple : <dtml-with "Images.Banner"> .... loads of html and <dtml-var> expressions </dtml-with> when i was using "/locations/index_html?category=hotels" i had no problems, but now using "/locations/Hotels", i get this error : Zope Error Zope has encountered an error while publishing this resource. Error Type: AttributeError Error Value: __call__ File D:\Inetpub\Moo\lib\python\OFS\DTMLMethod.py, line 141, in __call__ (Object: mtdBanner) File D:\Inetpub\Moo\lib\python\DocumentTemplate\DT_String.py, line 502, in __call__ (Object: mtdBanner) File D:\Inetpub\Moo\lib\python\DocumentTemplate\DT_With.py, line 148, in render (Object: Images.Banner) AttributeError: (see above) which looks like a namespace problem. hoping somebody can help. either that or advise a better way to manage this with more zope-zen. (my current method seems a bit of a pain in the butt creating all these folders for all the categories and subscategories... and not as flexible for changes). eg. for the "Restaurants" category, i have 40 subcategories, each requiring a folder to get the value of 'subcat'. the price to pay for simpler URLs ? cheers, chas
