[Zope-dev] Adding properties in __init__
Hi,
I have a product class that subclasses SimpleItem and PropertyManager.
If I try and add a property in __init__ as so:
self.manage_addProperty('AProperty','1\n2\n3','lines')
I get the following wonderful error:

Error Value: aq_base
I'm guessing that this is because self isn't an acquisition wrapper in
__init__ (even though SimpleItem is Acquisition.Implicit) but what am I
supposed to do to add a property in __init__?

I usually override _properties in the subclass, with the new property

self.Aproperty = '1\n2\n3'
works nicely.

__init__ has no idea of context, so its less useful in Zope than you
might usually expect.
Your object must have a factory method somewhere I suggest adding
an extra method to your object (I always name it '_after_create') and
arrange for it to be called by your factory once the new object is
installed in its container.

Re: [Zope-dev] ZPatterns and Properties that are objects
At 01:01 PM 11/7/00 +0200, Roch'e Compaan wrote: I created a couple of ZClasses based on Dataskin. In the way I grok ZOPE, properties that are objects can not go onto property sheets. So if I have a Customer ZClass that has a property Address (a property that is an object) then I would create the address object as a "method" of the Customer that makes references like Customer.Address.Street possible. The way Ty and I usually handle "object" properties is to give an object setter methods (e.g. "setAddress()") that simply set the property (e.g. self.Address = addr). The only downside is that you have to do this in a Python base class or an External method. Later, we expect to replace this approach with PropertyHandlers, and we already have a primitive form of PropertyHandler we have used with some success, but it's too crude at this point for a product release. To achieve this without ZPatterns I would base my ZClass on a objectmanager so that I can create an instance of an Address object within Customer. So how does one do this with ZPatterns. In one posting I picked up that one does not have much joy with ZPatterns and the ObjectManger base class? I have created ObjectManager and Folder dataskins before and had them work, but at the time I was testing with Zope 2.1.6, and it was an older version of ZPatterns. I haven't done much lately with them.

Re: [Zope-dev] DataSkins containing DataSkins
At 05:39 PM 11/6/00 -0800, John Eikenberry wrote: The base DataSkin will be in a Rack. Would there be any issues in making the embedded DataSkins (contained on the base DataSkins) use this Rack as well? Seems like it might result in the confusion about which DataSkin a PlugIn on the Rack worked with. Yes, it would, if you persistently stored the DataSkins in the other DataSkins. If you use an Attribute Provider, however, that loads them from a different Specialist+Rack, you'd be fine. Would it be better to use Customizers in some way... either have the base Dataskin or perhaps the Specialist also inherit from the Customizer? Ugh. Well, you might be able to make the DataSkin a Folder w/Customization Support... but I don't know if it would work. I've never tried mixing a DataSkin with the classes that support DataSkins. I think there might be some horrible method naming conflicts. Phillip, I think you've considered this (didn't you once mention converting PropertySheets to DataSkins). What issues do you think I should be aware of in planning for this. Doing DataSkin propertysheets would be done by having the propertysheets come from a different Specialist. Thing is, if you want to store DataSkins arbitrarily nested within one another, you can do it in the regular Zope management structure, without using a Specialist/Rack combo. On the other hand, if you have a structured nesting, (e.g. object type A contains some number of object type B), then you should be using attribute providers/SkinScript to define how those sub-objects get stored. To use ZPatterns for its intended purpose, it is critical that you step back and NOT think in terms of how you'd implement a solution in Zope without ZPatterns. In fact, it is important that you not think of implementation *at all*, because it will distract you from the real question, which is how to segment the responsibilities of your application. Once those responsibilities are segmented, implementation is simply a matter of writing the necessary methods and SkinScript. In this case, segmenting according to the RIPP model means that objects are never truly "contained" in other objects. An object just gives you ways to get at related objects. And if there is a relationship between objects, that means that the object on the "other end" of the relationship plays some role in your system, and where there's a role there almost always needs to be a Specialist. Now, it may seem that this is needlessly constraining, because it is more restrictive than Zope. After all, Zope lets you put anything in anything -- just like Basic lets you go to any line in the program. :) ZPatterns, however, exists to make interconnectable frameworks possible. You can still do the kinds of things Zope can, but you must explicitly think through your application's role model, and seperate the responsibilities accordingly. The payoff of this more rigorous design approach is that your application can be backed by *anything* that can support the data, including combinations of different kinds of data stores. And, your application will be a potentially re-usable framework. ___ 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 )

Re: [Zope-dev] Questions about implementing object models with ZPatterns
At 05:19 PM 11/1/00 +1100, Itai Tavor wrote: Ok... I think I get the "Specialist per role, not per class" part. But I still can't make the jump from a class diagram to a ZClass/Specialist setup. A class diagram contains all the roles - they're the lines between the classes. :) Look at it this way... if an object has a particular association role that it needs filled, and there is more than one kind of object that can fill that role, then presumably those objects must all implement a certain interface, right? You need to create a Specialist for that interface. In other words, there is usually one Specialist per collaboration interface -- which is NOT a one-to-one mapping with classes, since some classes may implement multiple interfaces, and some classes may all implement the same interface. I can solve some of it by subclassing ZClasses. So, if I need Customers and Resellers, I'll make a Specialist for each, and a Customer and Reseller ZClasses, both subclassed from Person which stores common properties for a person. This part is ok. What *role* do Customer and Reseller objects play in your system? It sounds to me like perhaps they play the role of "thing that places orders" or "thing that orders are shipped to". Depending on your application's functions, you could need as many as FOUR specialists: Customers Resellers BillableEntities ShippingDestinations Where the latter two specialists would contain a pair of Racks that mapped back to the Customers and Resellers specialists, respectively. But it gets more complex than that. Take this example: Every OrderLineItem object can have one or more Payment objects associated with it. There are 3 possible payment types - Check, Charge and BankDeposit, so I make a ZClass for each one, all subclassed from a general Payment ZClass. I create one Payments Specialist with 3 Racks. Where do I store methods that are specific to one payment type? In the Rack? I can't store them in the Specialist - it would be a mess, and I can't store them in the ZClass, because the ZClass doesn't know about the rest of the application. Huh? What do you mean by "methods that are specific to one payment type" in this context? What do payments do that requires knowledge of the rest of the application? If it's a problem-domain method, it belongs in the ZClass. Actually, writing this down makes me realize that it could work... would Payments.getItem(some_payment_id).someMethod() call someMethod in the Rack if one exists, and the one in the Specialist if not? No. DataSkins acquire only from the Specialist, not the Rack. However, you can use ClassExtenders in the Rack to provide methods to an object. But you *can't* override methods that already exist on the ZClass. This should not ordinarily be an issue since you should only be doing problem domain methods on your ZClasses anyway, and there should be no need to override them. Another problem I'm having is how to store id's for different objects in the the same field. In the Payments example above this is not a problem, because all payments are supplied by the Payments specialist. But what about another example - Customers and Resellers are two totally different roles, so they each get a Specialist. the Payment object has from_id and to_id fields, and each of those can hold the id of a customer or reseller, or some special code to indicate the store. I could add from_type and to_type fields, or I could prefix the id with a code letter, but neither seem like a good solution. Is there a recommended approach for solving this problem? See above, where I mention BillableEntities and ShippingDestinations. Having only one specialist per role means that you never have to worry about ambiguous identities. Please note, however, that at this stage of design you shouldn't be looking at how the references are going to be stored. At the abstract design stage, you would just have "Payor" and "Payee" attributes that are the actual related objects. When you write your SkinScript later, you can set up how the linkages work, using ID fields, or SQL columns, or whatever. ___ 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 )

[Zope-dev] Vote on the new name for Python Methods!
Being Election Day in the United States, now is a good time to vote on the new name for Python Methods. Python Methods are a relatively new concept for Zope. They give you the features of DTML, such as through-the-web editing and security, while providing a familiar, refined syntax. But before we can fold them into the Zope core, you need to help us choose the right name for them. Some have voiced the opinion that the name "Python Method" is confusing because it can just as easily refer to methods in standard Python modules. There are some interesting alternatives, so please cast your vote! http://www.zope.org/Members/hathawsh/poll ___ 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 )

[Zope-dev] JPython Product?
I have been toying with the idea of creating a Zope product for creating JPython applets within Zope. I thought this might be a way to increase the capabilities of Zope on the client-side while remaining firmly grounded in Python and simultaneously giving me an excuse to play with JPython and maybe create a useful Zope product too. I wanted to throw this out to the group to see if others thought this was a worthwhile capability. The basic idea would be to write JPython scripts and applets in Zope either via the web or otherwise and automagically "compile" them into transparent .jar files that are served to the client on request. Sounds so simple! Right?? Somehow I doubt it will be, but... From what I see no one has done this so I figure at least one of following is true: 1. Nobody thought of it or felt compelled to act on the thought. 2. Its gonna be hard to do. 3. Somebody else already did it and I don't know about it. 4. The idea blows. Any thoughts on this idea, + or - are appreciated. -Casey D. ___ 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 )

Phillip J. Eby wrote: At 05:19 PM 11/1/00 +1100, Itai Tavor wrote: Ok... I think I get the "Specialist per role, not per class" part. But I still can't make the jump from a class diagram to a ZClass/Specialist setup. A class diagram contains all the roles - they're the lines between the classes. :) That's a great statement :) It really helps me decipher my object model. Look at it this way... if an object has a particular association role that it needs filled, and there is more than one kind of object that can fill that role, then presumably those objects must all implement a certain interface, right? You need to create a Specialist for that interface. In other words, there is usually one Specialist per collaboration interface -- which is NOT a one-to-one mapping with classes, since some classes may implement multiple interfaces, and some classes may all implement the same interface. How do you decide where to create collaboration Specialists? You wouldn't have one for every line in the object model, right? Do you use one only where there is more than one kind of object that can fill a role? How do you determine if a collaboration interface requires a collaboration Specialist, or can be done with a direct connection between the two class Specialists? For example, take an OrderLineItem object and a ShipmentLineItem object (one describes a quantity of a certain product added to an order, and the other that quantity of product being shipped). In the interface between OrderLineItem and ShipmentLineItem, an OrderLine can be seen as filling the role "thing that is shipped". OrderLineItem also fills the role "thing that is purchased" when it is added to an order. Would you create Specialists for each of these roles? Or, in the case of BillableEntities below, would you still use this Specialist if there were only Customers in the system (so, only one participant filling the "thing that places orders" role)? Are collaboration Specialists only used to interface participant-type objects? I can solve some of it by subclassing ZClasses. So, if I need Customers and Resellers, I'll make a Specialist for each, and a Customer and Reseller ZClasses, both subclassed from Person which stores common properties for a person. This part is ok. What *role* do Customer and Reseller objects play in your system? It sounds to me like perhaps they play the role of "thing that places orders" or "thing that orders are shipped to". Depending on your application's functions, you could need as many as FOUR specialists: Customers Resellers BillableEntities ShippingDestinations Where the latter two specialists would contain a pair of Racks that mapped back to the Customers and Resellers specialists, respectively. The collaboration Specialist won't actually *do* anything, would they? They would only abstract the retrieval of participant objects, so that any object which requires a "ship_to" property will not have to know or care what kind of participant is referred to. Am I getting this right? (Of course, I could add PD methods to ShippingDestinations if I wanted to, like printShippingLabel, but in a basic application this Specialist doesn't seem to need to do anything at all). Also, these collaboration Specialists seem to serve to hide the fact that there are two types of participants. So, for example, a Payment object would just know "things that get billed". So how would I ask the Payments Specialist for "all payments made to resellers"? But it gets more complex than that. Take this example: Every OrderLineItem object can have one or more Payment objects associated with it. There are 3 possible payment types - Check, Charge and BankDeposit, so I make a ZClass for each one, all subclassed from a general Payment ZClass. I create one Payments Specialist with 3 Racks. Where do I store methods that are specific to one payment type? In the Rack? I can't store them in the Specialist - it would be a mess, and I can't store them in the ZClass, because the ZClass doesn't know about the rest of the application. Huh? What do you mean by "methods that are specific to one payment type" in this context? What do payments do that requires knowledge of the rest of the application? If it's a problem-domain method, it belongs in the ZClass. Ok, I get this now. This question was based on my lack of understanding of how a ZPatterns application is structured. A Payment object needs to access other parts of the application - for example, to get a UI snippet from BillableEntities. I thought that ZClasses are supposed to be self-contained, without links to the rest of the app, while methods that link parts of the app together belong in the Specialists. I can see I was totally wrong in this. Please note, however, that at this stage of design you shouldn't be looking at how the references are going to be stored. At the abstract design stage, you would just have "Payor" and "Payee" attributes

Re: [Zope] Your thoughts about Zope-based database apps
From: "Alonso Rhenals" [EMAIL PROTECTED] Subject: [Zope] Your thoughts about Zope-based database apps 1. Is Zope a good tool to quicky build an efficient effective user interface for a database application? Yes. Once you get the hang of it it is all quite easy. I have at least one (building another) site that is about 90% driven by the data from a PostgreSQL database. 2. In particular, what would be the best way to implement the inserting and updating of records along with input data validation? (Retrieving data from a database to show on a web page using Zope is straightforward as you know.) ZSQL Methods. 3. In several cases I'd like to implement a main form/subform, where the subform allows the user to enter several items related to only one record in the main form. Since every item might have many fields (say 20) I'd like to present just the most important fields on a table, and allow the user to view/enter/update all the fields for each item in a different web page. Those of you familiar with Microsoft Access know that in Access it is straightforward to implement this main form/subform interface. I wonder what would be the best way of implementing this using Zope? You would have to build it. Not that it would be that tough. You could also use a Zope Wizard if you want to do a couple of forms. 4. Do you know of any existing Zope-based app similar to this?. Obviously, the back-end doesn't have to be MySQL. http://fundraising.gotschool.com - Although you can't see the management interface which has lots of ways of extracting and updating data through forms and ZSQL Methods.

[Zope] PythonMethod and accessing objects in the ZODB

RE: [Zope] Your thoughts about Zope-based database apps
Hi Alonso, FYI, some of the list members have great difficulty in reading HTML formatted messages. It's best if you set your format to "Plain Text" before submitting to the list. I haven't yet implemented what you are considering, but I am interested in doing so soon. So, I am very interested in what you discover. If you don't mind, if/when you receive any emails that don't get CC'd to the Zope mailing list, please forward them on to me, too. I am an Access programmer and have a bit of experience with MySQL. I've given a lot of thought about how one would handle an Access-like interface with Zope and MySQL over the web. I'm anticipating a lot more development time building the interface, but saving a bunch of time by not having to keep multiple copies of the same DB up to date. If you feel like brainstorming on the "whats" and "hows" of such an application, I'ld love to join in. Thanks, Eric. 2. In particular, what would be the best way to implement the inserting and updating of records along with input data validation? (Retrieving data from a database to show on a web page using Zope is straightforward as you know.) I have a set of java script functions that I use for form field validation. I like this approach because it puts the burden on the client. However, there are Zope products available that handle it on the server side. Search Zope.org for "Smarter Forms" 3. In several cases I'd like to implement a main form/subform, where the subform allows the user to enter several items related to only one record in the main form. Since every item might have many fields (say 20) I'd like to present just the most important fields on a table, and allow the user to view/enter/update all the fields for each item in a different web page. Those of you familiar with Microsoft Access know that in Access it is straightforward to implement this main form/subform interface. I wonder what would be the best way of implementing this using Zope? Using Zope to mimic a form / subform combination means that Zope will have to generate a the input form and subform elements together before they get sent to the user. The user will then update the data sent by Zope. When the form is submitted, Zope will have to update the main form data, then iterate thru the subform elements, modifying the subform data with each iteration. If records are to be added, it will require a client server transaction for each record added (unless something is done with javascript, where the form is generated dynamically. Then, the user could add many records and when the dynamically built form is submitted, Zope will have to figure out how many records the user added). 4. Do you know of any existing Zope-based app similar to this?. Obviously, the back-end doesn't have to be MySQL. I haven't seen any yet, but I'm sure they're out there! ___ 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 )
Re: [Zope] Persistence triggering
But can I also do? self.list = self.list + [item] Yes... this works because you're treating it immutably. Although this is likely much slower than an .append because the interpreter needs to make a copy of self.list before tacking on your item. You can also do: self.list.append(item) self._p_changed = 1 This explicitly tells the ZODB to include the object represented by self in the current transaction. ___ 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 )

[Zope] How about create another method other than index_html to get content in OFS::File?
Dear all, My problem is that : I have a ZClass based on OFS::File. I need to override the default index_html for my own purpose. After I created my own index_html, I found myself can't access the content of that object. Since: 1. I have no way to access the original method index_html of the base class 2. In OFS::File, There is no other method than index_html to access the content of this object. That's why I modify Image.py and add one line: getContent=index_html It's work for me. I don't think it's a good idea, since it's quick and dirty. Is there any better way to do this?
