hi folks, first off, thanks to the people who offered quick, helpful responses to my question yesterday. ok, i'm converted. i've started implementing in zope. i have a relational database of about 8 tables. it is used for a registry of trainings and trainers. we have ten centers that will offer trainings. each center needs a publicly accessible home page where people can search on data in the database. also, each center needs a management section, where they can insert/edit/delete data and more. this section is restricted to certain validated users. my question is how to structure this in zope. i started by creating a centers folder, and a subfolder for each center. i plan to place common DTML docs and SQL methods in the centers folder, letting each center acquire them. each center has an ID property, corresponding to its unique ID in the database. i just noticed this morning that this is the same way its done in the budget sample application in the HOWTO section. i must be going in the right direction. i expect to have a number of DTML documents that are access restricted. for organizational clarity and ease of managing the permissions, i'd like to put them in a folder. but if i put them in a folder in the centers folder, then they are parallel to the individual centers and can't be acquired. does this mean i'm stuck putting them all in the centers folder? any suggestions? lets say i put a DTML document called dtViewTrainings in the centers directory. it uses a SQL method and an ID property to get trainings from the database. so the user views http://.../centers/roswell/dtViewTrainings and the ID is acquired from the roswell folder. everything's ok. but what if they browse to http://..centers/dtViewTrainings. there's an error because ID is not defined. that's fine, because the request makes no sense. but is this problem? it just kind of bugs me that the user could browse to this URL and get a meaningless error. thanks in advance for any help, -scott ----- Scott Lewis Baltic Avenue Productions csl@balticave.com
