[Zope-dev] DB(Oracle) Transactions with Zope(/ZPatterns)
Hi *, i'm currently developing a (network information) DB web-interface using ZPatterns specialists with one specialist for every logical object. For instance i have a 'component'-specialist which handles a object-table mapping for the tables: o component - product (n:1 foreign key) - location (n:1 foreign key) - physical port (1:n foreign key) - ... The user (provided that she/he has permission) should be able to create a new component as well as related physical ports, new product etc. 'create component' Sequence: (1) call component-specialist newItem - skin script 'WHEN OBJECT ADDED' calls SQL insert statement with default attribute parameters from ZClass ### + SQL commit (Zope/DC Oracle default behavior)! ### (2) redirect user to .../component/#newid/edit (3) user adds new physical port - skin script 'WHEN OBJECT ADDED' calls SQL insert statement with component #newid as foreign key + default stuff from ZClass again an SQL commit-statement is appended ... (x) user clicks 'cancel'-button - MY PROBLEM (trash in DB because of no(?) possibility to make a SQL rollback) Questions: -- 1. Is it possible to make sure a user stays with a specific DC Oracle thread ? (trick timeouts via http-refresh ?) 2. Provided that a user can have her/his private DB thread (kind of a private xterm with PL/SQL ;-) is it possible to wrap a bunch of SQL statements (triggered by ZPatterns) into a (Oracle) DB Transaction ? Any comments (maybe answers ;-) would be _very_ appreciated. thank u in advance Andy -- Andreas Repp [EMAIL PROTECTED] Leibniz Rechenzentrum Muenchen www.lrz.de Barer Str. 21 office +49 8441 4980772 D-80333 Muenchen mobile +49 172 8337010 -- ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

I'll add some more specific questions where my understanding gets muddled to illustrate this Where _I_ get stuck is: 1) How do Racks (and their associates) relate to normal propertysheets and how to attributes. What is the relation to objects? 2) What do I add to a Rack and what to a Specialist to get a) a property b) a propertysheet c) an object 3) How do I switch from one implementation to another (for example from persistent storage to non-persistent storage) and what parts do I have to update 4) if I add a SkinScript, what does it really do? How does it relate to my Rack, and how to the Specialist? How can I use it and where do I use it - in the Rack or in the Specialist, or do they both have their own domain? 5) How do I talk to a Specialists? What will it say back? For example, if I have a 'virtual object' (let's say a person that gets its properties from ad RDB and is accessed by its name), should I be able to access it by direct URL traversal blabla/WhateverSpecialist/Name or do I add a querystring blabla/WhateverSpecialist?name=Name There should just be some annotated step by step guides.

Property sheets created on ZClasses always have their data stored in attributes of the object itself, so if you want to control those property sheets you would not use a sheet provider at all.

The Specialist asks its racks for an object. The Rack which "retrieves" the object tells the object that it belongs to the rack and should ask the rack for anything it needs. When the object needs a property sheet or attribute or whatever, it asks the rack to give it a list of relevant providers for that attribute/sheet/whatever. It then walks the list asking those providers if they can perform the function it desires. If none of the providers are successful, it performs a default behavior (such as raising an AttributeError to indicate the attribute does not exist). This general pattern is followed for almost anything that can be delegated from a skin to a provider. I considered the scenario where attributes are stored external to the object according to the filing clerk analogy on the wiki: The Specialist (filing clerk) asks its racks (filing cabinet) for an object (dental records). The rack (filing cabinet) tells the object (the dental records) that it belongs to the rack AND that the object should ask the rack for anything it needs. Why would the object "need" anything. Is it not the specialist with the "need"? If object data is stored external to the dataskin object does the dataskin only implement behaviour? I find it difficult to understand because I associate Dataskin with Storage. If object data is stored externally is it stored in Persistent Property Sheets? How does one define properties for Persistent Property Sheets?

Property sheets created on ZClasses always have their data stored in attributes of the object itself, so if you want to control those property sheets you would not use a sheet provider at all. Sheet providers are only used to provide property sheets whose data is stored external to the object. The "name" refers to sheet names, yes, although again these are not ones created on the ZClass, which will be handled by the ZClass. The "namespaces" refers to the XML namespaces of the property sheets, which is a WebDAV thing. In the WebDAV protocol, "property sets" are added/changed using URLs as XML namespaces. So you could have a property sheet whose XML namespace is "http://www.zope.org/PTK/MemberProperties" and whose name is just "MemberProperties" or "MemberInfo" or something else altogether. ZPatterns supports WebDAV, and WebDAV requires the ability to add arbitrary property sets with arbitrary properties to an object. Also, the XML namespaces concept can be useful as a way of avoiding name collisions between frameworks. From the IRC_Chatlog: "Call "getItem(key)" to retrieve an item from the Specialist, and "newItem(key)" to create a new item in the specialist." Does this imply that I can simply call "newItem(key)" from a dtml-method inside the specialist to create a new instance of my object? Yes. I think I understand ZPattern architecture somewhat but get lost on the implementation side, particularly at that place where attributes are retrieved from storage or more clearly how a specialist(datamanager) links up/communicates with a sheetprovider (data-plugin) and how the sheetprovider in turn communicates with the rack and how the rack retrieves from storage (dataskin). A very simple outline like this would help me a lot, eg: Specialist to Sheetprovider (handled in IDE - add a SheetProvider under Plugins) Sheetprovider to rack (handled in IDE - select Storage Class under rack) Rack to Dataskin () Dataskin to physical storage () Roché PS: I would be more than willing to document my enlightenment in a howto The Specialist does not talk to the sheet provider. The Specialist asks its racks for an object. The Rack which "retrieves" the object tells the object that it belongs to the rack and should ask the rack for anything it needs.

This general pattern is followed for almost anything that can be delegated from a skin to a provider. When DataSkins are used outside a rack, the process is similar, except that the DataSkin itself notices it is being retrieved from somewhere and has not been told it belongs to a rack, so it searches its acquisition path asking for a Customizer. Once found, it then uses the Customizer in the same way as it would have used the Rack (i.e. to ask for lists of providers that might be useful for performing tasks it needs done). ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

I created a ZClass called "Product" with Dataskin as baseclass. I also added a specialist called ProductManager containing a default rack. Under storage for the rack I selected the newly created Product ZClass. My product ZClass needs to query both a RDBMS and the ZODB for attributevalues. At this point I get lost.

That said, can you give em an example where it would eb useful to have one object stored in multiple racks? cheers, Chris ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

What class are you talking about? ;-) This is why I said it might be useful for the rack's delete just to call delete on the object.

Re: [Zope] ZPatterns: Deleting objects from a Rack?
Thus spake Chris Withers ([EMAIL PROTECTED]): Ty Sarna wrote: call the manage_delete() method on the object. That is, you ask the object to delete itself. This seems unnecessarily long-winded to me. What are the reasons for it being like this? (examples are good... ;-) However, once you have the object, operations on the object should be done as methods on the object. I'm sure it's against Demeter's Law (I've read the Wiki ;-) to work this way. You should ask the rack to delete an object and it can process this how it wants... most often this would be by asking the object to delete itself, but maybe it's be more efficient for the rack to just delete the object (for example, if the object is actually a row in an SQL table) I could be mistaken about this, as I'm still having trouble following the ZPatterns train of thought, but I think the reason that the object needs to delete itself is that the object may not be stored in a single place. For instance, the object might be created from 5 rows from seperate tables in an SQL db and 2 attributes gotten from LDAP. I'm not entirely clear how asking the object to delete itself in this case is going to improve the situation over just asking the rack to, but I think that was the intent. sRp -- Scott Parish http://srparish.net PGP signature

[Zope] ZPatterns: Deleting objects from a Rack?
Ok, I have a stupid question. I have succeeded in creating a ZClass (a subclass of DataSkin) and instantiating a few instances in the defaultRack of my Specialist using my Specialist's newItem() method. Rock. However, search as I might, I cannot figure out how to delete an item once it's been created. On gut instinct, I figured there would be a deleteItem() to complement the newItem() method. No such luck. What am I missing? Is there a management tab I'm not clicking on somewhere? A method I haven't found? A clue I don't have? :-) Thanks, --Jeff --- Jeff K.

[Zope] ZPatterns, Hello, world.
Hello, I am trying to wrap my head around ZPatterns--I am hoping to use it in a project I am currently working on.

Re: [Zope] ZPatterns, Hello, world.
Hi, I don't know of a ZPatterns "Hello, World". I remember feeling quite pleased when I managed to get a ZClass instance added to a Rack. Of course, how one would define "Hello, world" in the context of ZPatterns, I'm not sure. I haven't yet had a chance to use 0.4, so this example won't mention DataSkins. You could do something like this: create a ZClass add a Specialist add a Rack set the storage for that Rack to your ZClass add a PythonMethod to the Specialist that calls newItem(ObjID) and then sets some properties on that ZClass Then, you can go to http://yoursite/Specialist/ObjID and take a look at your ZClass. Congratulations! You've now replicated the functionality of a Folder :) (Of course, the Rack uses BTrees, so you can store any number of objects in there, unlike a Folder.) Once you have objects in your Rack, you can start playing with attribute providers and such. Plug-ins still need to be written in Python. HTH, Kevin - Original Message - From: "Jeff K.
