EOF - Cayenne [Was: Hibernate]
If you can't use WO/EOF for whatever reason, just switch to Apache Cayenne - user-friendly, powerful and open source. And it will convert most EOModels via the GUI for you (and give a good enough approximation for those that it can't convert). Seems like a straightforward choice to me ;-) http://cayenne.apache.org/ Cheers, Andrus On Mar 24, 2009, at 9:26 AM, Jérémy DE ROYER wrote: I do agree with Pierre.

Fwd: Change rewriteURL
Hi, I want to use it for outgoing URL's. The method you mentioned doesn't have any context, so unfortunately I can't use it. I need to have the user settings from the Session to put them to the URL. This is because I need to know one setting of the user when the user would get a session time out, I'm missing the user settings to direct the user to the right page.

The current content on the wiki is quite old refers to WO 5.1 and 5.2, referencing copying the frameworks from the installation CD.

Re: Webobjects design: multiple editing contexts
Mark, I pass editing contexts through components all the time - it's a nice clean way of having a set of components work in a context mode, and it's really the only clean way I can think of. Of course, you could just ask the EO that you pass down (presumably to edit the same object or children) for the context, but I find passing it down explicitly to be cleaner. You could always use children if you have sub-editing to do where you don't want it to affect the parent until you're done - but I find that I seldom have that type of situation (usually, the user wants to cancel the whole thing, not just a part of an edit).

Re: Webobjects design: multiple editing contexts
On Mar 24, 2009, at 8:44 AM, Mark Wardle wrote:

I do the same thing that Kieran suggested. My component has an
editingContext() method which creates its own editing context.
If so, is it appropriate to pass a handle to
the editingcontext between components? For example, I have a UserEdit
component, that takes a User as a binding, and allows a user to edit
that user's details (subject to permissions).
You could do that as long as it's okay to mess with that editing
context. But you could run into trouble, for example if you start
editing your User object and then go somewhere else in the
application, modify something and save then if the editing context is
the same as the one used for these components then you may be saving
the pending edits to the User object as a side effect and not exactly
what the user would expect.
Soo... what I do is, if your UserEdit component is being handed the
User object then it can simply get a copy of of the user object into
the UserEdit's local editing context. I do this in a couple of
different ways. Here's the one with less code:
/** Returns copy of user object in the UserEdit's local editing
context */
public User user() {
User user = (User) valueForBinding(user);
return user.localInstanceIn(editingContext());
}
But you could have trouble here when they start editing the user
object and then in a subsequent request you are handed in a different
user object. All of a sudden you will start editing a different user
object and you still have pending edits for the other user object.
So what I do is usually the version that involves a bit more code. I
you are using project Wonder and your component inherits from
ERXComponent then I usually do this in preAppendToResponse as follows :
public preAppendToResponse(WOResponse response, WOContext context) {
// See what user object we're being handed in
User aUser = (User) valueForBinding(user);
// Convert it to our local editing context
aUser.localInstanceIn(editingContext());
// If the user handed in is a different user from the one we're
currently editing...
if (user != aUser) ) {
// ... then throw away any pending edits ...
editingContext().revert();
// ... and start using that user object
user = aUser;
}
}
public User user() {
return user;
}
Now in the real world sometimes I get handed in a brand new object
which was created in an external editing context and which is okay to
mess with. For example let's say the parent component is the one that
hands in the user object to the UserEdit component, and let's say that
it was created like this prior to be handed in to UserEdit:
EOEditingContext newEditingContext = ERXEC.newEditingContext();
User aUser = new User();
newEditingContext.insertObject(aUser);
aUser.setFoo(foo);
Then your user edit is handed in this user object. In this case I
assume that I can use that editing context and can have the following
bit of code in preAppendToResponse():
// See what user object we're being handed in
User aUser = (User) valueForBinding(user);
// See if it's a new object and not exactly the one we're currently
editing
if (aUser.isNewObject() aUser != user) {
// use the externally created editing context as the local editing
context
_editingContext = aUser.editingContext();
user = aUser;
}
Ok... so that's close to what I do normally. Not sure if it's the
best way, but it seems to work for me.
What if I then have subcomponents that need to use the parent editing
context? Is it appropriate to get the parent's editingcontext from the
EO itself?
I document this for the component. For example, in your UserEdit
component documentation I would mention that it uses its own editing
context for editing unless the user object handed in is a new object
that has not been saved to the database yet.
Once I start thinking about that, it looks like I'm writing lots of
code which is fairly repetitive and thought that there must be a
better way? Am I missing something obvious? I don't want to make
things highly modal, and I usually don't wish to preserve state
between components unless the user specifically requests it.
Yes I've thought about abstracting that code so I don't repeat it.
The user i-var and binding could be called document.
And have that code in a superclass in preAppendToResponse(). Then the
UserEdit component would extend that component. If your subclass has
some code in preAppendToResponse then you would have to call
super.preAppendToResponse() to make sure that logic is not skipped.

Webobjects design: primary keys with business meaning and allowing users to type them in!
Following on from that question, I have one other design issue I map patients to local health organisations using their postcode (zipcode). I have a third-party sourced table with two columns: postcode and organisation id. Both are unique but have business meaning. At present, I am using the string postcode and string organisation id as primary keys. A user can complete an address for a patient, and types in the postcode. At the moment, I have a relationship defined with the text entered by the user as a foreign key acting as a lookup. I don't mind if the postcode doesn't exist as it may be a new postcode. I can therefore say: patient.currentAddress.postcode.localHealthBoard.name and get the name of the health organisation for that patient. As you can imagine, there are quite a few postcodes in the UK. I've therefore used a one-way relationship to avoid excessive fetches. However, this isn't working - WO complains about not having a null relationship - presumably because I've sneaked in behind EOF's back and set the foreign key directly. Solutions? 1. Instead of a relationship, perform a manual lookup when the postcode is entered and then set the relationship directly in the proper way (addBothSides...). Problem then is keeping items in sync and making sure that when the postcode is changed the relationship is updated. In particular, health organisation changes may change the mapping of postcodes to organisations - using a relationship keyed to postcode will magically update. Manual lookup won't do that. Plus: when to do manual lookup - during an action - when the mapping table is updated? what if there are several components that need this 2. Somehow set the relationship just before the ec.saveChanges() step - but I know I'm not allowed to do that during validateForSave() - when can I do it? Can I hook into the object lifecycle? I've read Chap 3 of Practical Webobjects and see one method there for notifications. 3. Am I missing a simpler method?

fix! Will digest the rest!
My components normally do this:
public boolean synchronizesVariablesWithBindings() {
return false;
}
So I pull the values when I need them on demand using valueForBinding().
And if I need to set the value for a property bound to a foo binding
I simply do this:
setValueForBinding(null, foo);
And I make sure I edit the .api file and make foo settable. So that
the component editor gives you a warning if somebody binds a property
to foo that is not settable, i.e. a constant value bound to foo.

A few basic questions about EOF
Imagine the following model, where a User has a many to many relationship with Message. A user can have many messages and messages can be read by many users. User --- Message I can model this in EOModeler as a flattened relationship, and as expected this will create the many-to-many indirection table UserMessage for me. User -- UserMessage Message In the User entity it creates a relationship property messages() that allows me to bypass the indirection table (and users() in Messages). Now for the questions: 1 == In the deprecated EOModeler User Guide it states: Primary key propagation is also commonly used to generate primary keys for join tables in many-to-many relationships. If the join table has a compound primary key (consisting of the two foreign keys to User and Message), how does this apply? 2 == Does anybody know how does WebObjects manage flattened relationships internally? Basically I want to know if (besides having more readable code) I get some performance improvements using this. So which are there any performance differences in these two? user.messages(); or user.userMessages().valueForKey(message); 3 == Now imagine I need to know if a user has read a message. I would simply add a boolean to the indirection table to store this. Can I still use the flattened relationships WebObjects provides and store this boolean in the indirection table? Are there any caveats I should be aware of? 4 == Theoretically if a message has no relation to users, it should be deleted. Does Owns Destination work in this many-to-many scenario? 5 == Not directly related to this scenario but I still couldn't quite figure out: When doing a addObjectToBothSideOfRelationship how does EOF know which relationship is the inverse relationship? In Core Data this is explicitly set but not in EOF. Sorry if this was a bit too long, but I'm trying to tie up loose ends in my mental model of EOF. Thank you for your time, Paulo F.

Re: Ajax inside a Repetition
Yes, I forgot to mention that the ID is unique, I'm appending the rowNumber to each ID. The whole repetition is wrapped in an AjaxUpdateContainer. When you check the checkbox, I need it to hide/show the calendar. I just realized I forgot to leave the conditional on the calendar column that hides/shows the field if the checkbox is checked. Tried changing the AjaxObserveField's updateContainerID to the outer container 'ListUpdateID' and still no luck. When an item is added to the repetition, only the checkbox and calendar in the first row work.

[ANN] AjaxDatePicker and AjaxDefaultSubmitButton
In the interests of keeping folks up to date with what is getting
added to Wonder...
AjaxDatePicker
Shameless port and adoption of Rails Date Kit (Swazz Calendar with
extra goodness). This input understands the format symbols %d, %e, %b,
%m, %B, %y, and %Y. See the NSTimestampFormatter for what these
symbols do. This component can also understand the corresponding
symbols from java.text.SimpleDateFormat. You can use any date format
allowed by these symbols. The translation from SimpleDateFormat
symbols to NSTimestampFormatter symbols may have some defects.
Localization is also supported. The AjaxExamples page shows a French
version.
NOTE: the AjaxDatePicker does NOT play nice with the
AjaxModalDialogOpener. There is some sort of initialization conflict
(I think) with Prototype that leaves you with a blank page and the
browser waiting forever for something (and I have not been able to
determine what it is) as soon as calendar.js loads and initialized. It
will work if the page the AMD appears on explicitly loads the
calendar.js in it's HEAD:
public void appendToResponse(WOResponse response, WOContext context) {
super.appendToResponse(response, context);
ERXResponseRewriter.addScriptResourceInHead(response, context(),
Ajax, calendar.js);
}
Full details in JavaDoc.
AjaxDefaultSubmitButton
Invisible form submit button that can be included as the first element
in an Ajax submitted form so that hitting enter performs the action
bound to this button. It supports most of the other AjaxSubmitButton
bindings.

Actually I've already solved this in my project. I asked this because
I found out about Owns Destination just a few days ago and it got me
wondering.
Basically I put a counter on Message marked for OL that serves as a
reference counting mechanism. Messages are related to Users on
creation, so I don't need to worry about the counter going up.
If two users unrelate themselves from a Message a the same time I get
an OL and try again. This way I can prevent dangling messages.

It looks for one that matches the join columns. I am not sure what
happens if you have two identical relationships, nor I am sure why
you would have two identical relationships.
Looking at the join columns makes sense. Thanks.

Theoretically if a message has no relation to users, it should
be deleted.
Does Owns Destination work in this many-to-many scenario?
This doesn't sound right. If this relationship designates
messages that have been read by users, then you are saying that a
message that hasn't been read doesn't exist. While this is an
interesting philosophical idea, I don't think it really
translates into the real world. Can't you have unread messages?
This is unrelated to the read/unread messages. The idea is simple,
if a Message is no longer referenced by any User it should be
deleted.
So if userA and userB are the only ones that have a relation to
messageA
userA.removeObjectFromBothSidesOfRelationshipWithKey(messageA,
messages);
userB.removeObjectFromBothSidesOfRelationshipWithKey(messageA,
messages);
editingContext.saveChanges();
At this point messageA would be deleted.
There is no delete rule that will do this. I'd probably implement
this on Message:
public void removeFromUsers(User aUser) {
super.removeFromUsers(aUser);
if (users().count() == 0) {
editingContext().deleteObject(this);
}
}
You might find this problematic if the last user can be removed
then another one added. This opens up all sorts of interesting
concurrency problems.
Actually I've already solved this in my project. I asked this
because I found out about Owns Destination just a few days ago and
it got me wondering.
Basically I put a counter on Message marked for OL that serves as a
reference counting mechanism. Messages are related to Users on
creation, so I don't need to worry about the counter going up.
If two users unrelate themselves from a Message a the same time I
get an OL and try again. This way I can prevent dangling messages.
Yes, that should be fine. When the counter can go up again, then
things get more interesting. Miguel lives for those sorts of
problems. ;-)

5 ==
Not directly related to this scenario but I still couldn't quite
figure out:
When doing a addObjectToBothSideOfRelationship how does EOF know
which relationship is the inverse relationship?
In Core Data this is explicitly set but not in EOF.
EOF is smart enough to look in the model and see that there is a
relationship on the destination that, in turn, has a destination
of the original object, therefore it must be the inverse.
Take the hypothetical case where there would be two relations back
to the source from the destination, what would happen then?

OpenBase and Cannot update primary-key 'fooID' from '1364' to '1364' on object of entity Foo
Hi All, I searched Google first for similar problems and I found some but I could not figure out what the resolution was. These were old messages (2004 or 2006 I think). But anyways, I think I have a clue. EOF thinks that the primary key value has changed but it hasn't. So my guess is that the value in the snapshot of the EO and the value in the EO are not matching... not completely sure why. I have the primary key fooID turned on as a class property in my Foo entity. I'm thinking that may have something to do. Maybe if I turn it off will make it go away. fooID in OpenBase is a foo_id of type long. In my eomodel I used the id prototype from ERPrototype. Which it says the external type is an int. But like I said, in OpenBase it is really a long. Could this long in OpenBase vs. int in my eomodel cause a problem like this? Has anybody ran into this problem with OpenBase?

Re: Getting Image File's Dimensions
Yeah, I actually have yet another framework (that isn't committed to Wonder (yet)) that also has a JNI ImageIO implementation for pulling image metadata. I don't recall if I wrote other variations of that one.

Hi!
