Expanding the User Object
by Alexander Schad 23 May '99

23 May '99

hi y'all! in a product we need to store a lot of data for a user, while still having to apply zope's access control features to it. it seems like we can not add our own objects (which are derived from accesscontrol.user.user) to the acl_users folder. are we doing something wrong or is there a work around or do we really have to store two different objects to achieve this goal? ciao, alex

Hmm, I may be off my nut here, but I think you need to pass in the HTML/potential-DTML, do your stuff to it, then render it by calling its __call__ method. Or the other way around. Or some such.

We've also taken a fancy to modelling the apps with UML. The whole notion of Actors in a system provides a very nice functional decomposition and DRASTICALLY simplifies security. I'd suggest a main application folder with at least one subfolder for Actors. In the Actors folder create a subfolder for each Actor. \TrainingRegistry \UserFolder (for security on the app) \Actors \Trainer \TrainingManager \TrainingEventManager \TrainingLocationManager \AppAdministrator Odds are you'll have some SQLMethods like: o sqlSelectTrainers o sqlSelectTrainingEvents o sqlSelectTrainingLocations which will probably be used ALL over the app. Put those on the Actors folder -- that way you can use them (often overloaded with Acquired variables) in all of the Actor folders without duplicating them (ooh, baad). Another pattern that's been useful is (as shown above) to put the lookup table care-and-feeding functions in a separate folder (AppAdministrator). This person adds, edits, and deletes new Locations, Counties, etc.. Of course your analysis may show that a Trainer might also need to add a Location -- in that case put the forms in Actors and acquire them. IMNHO, the BEST way to model this is with a UML Use Case diagram (it connects Actors with Use Cases). The need to use/reuse/acquire methods jumps right out at you. Note that ZClasses will likely cause us to evolve this approach.

If you do decide to return plain text then the calling DTML should create a temporary DTML Method to process the output. for example (untested) add a DTML method with id 'temporary' in your folder and add in your external method: self.temporary.manage_edit(out,'') where out is the relevant DTML content then in your calling DTML just render the temporary DTML method like:  Hope it works!

I've started to work on calculating storage requirements to determine server needs as I am also working on building my server. My app can easily be divided into multiple datasets or databases. One of the datasets I am looking at has a potential of 4+ million objects with each object requiring 15-50kb minimum. This dataset can be subdivided. Initially I will not populate the database will all of the items in their full form, but will populate as requests for data come. However I need to develop as if and plan for complete population. This makes for a very large database and one that spans more than one hard drive. Can Zope create and use multiple ZODBs on multiple hard drives? If so, how will such a large dataset affect packing and the creation of the backup file? Will I need to use multiple other database backends such as MySQL or possibly MetaKit?

FYI: News from the front, part 2
by Paul Everitt 22 May '99

22 May '99

Day One definately exceeded expectations. LinuxExpo has about the number of booths that I expected, but the quality of booths is pretty high. However, there are probably twice the number of attendees that I expected. The good news is that our booth is definately in the top half of "getting mobbed" booths. I nearly talked my voice out in the morning giving presentations at a feverish pace, then Chris nearly lost his in the afternoon. The plan was to have enough people at the show to have half in the booth and half walking around. Instead, the we've needed everybody around the booth. In case I didn't say it yesterday, the portal toolkit demo is awesome! We started with a nice surprise: copies of the new Linux Magazin with Zope on the cover! It is a really well produced magazine. We definately feel more credible being associated with something so well done. Jon Corbet from LWN came by for a demo and a one-on-one talk. He also had a nice surprise: a "Product Review", written by him, about Zope 1.10.2 in a new Linux magazine. Tom Jenkins and crew dropped by in the afternoon and spent about an hour with us, I believe. Saw the demo, then did some behind the scenese peeking at the code with Brian Lloyd. The highlight was at the very end, a couple of quite antagonistic folks came over and started taunting Zope. One of the guys was a Domino zealot. By then end, Jim was writing his application on the spot. They left with a grudging kudo. The Object Domain folks are here, need to get out of the booth and make some rounds.
