Inheritance and inverse relationships
Hi, I hope everyone had a good Christmas. During processing models and entities I stumbled upon a situation where I get an unexpected result. Basically I have an entity Parent with a subclass Child using single-table inheritance. Then I have another entity Gift that has a relation Parent -- Gift. Both relationships are marked as class attributes so Parent./Child.gifts() and Gift.presentee() return the correct objects. Now I am processing the corresponding EOModel objects and when I have the model for Child doing: EORelationship rel = childModel.relationshipNamed(gifts); EORelationship inverseRelationship = rel.inverseRelationship(); leaves inverseRelationship with a null value though it should have been set to the presentee-relationship. Digging into EORelationship. inverseRelationship() reveals that it compares the entity (Child in this case) with the destination entities from Gift. Too bad that it resolves to Parent so EOF simply says that there is no matching inverse. Seems as a bug to me. It should check for entity equality and then equality with any subclass if present. Any thoughts? I found the method EORelationship.anyInverseRelationship() that returns an internal inverse but of course that is not really useful when calling valueForKey on an object with the returned key name later on. jw ___ Do not post admin requests to the list.

Inverse Relationships
If I am using the EOGenerator files from WOLips is there not a way to
update a relationship without automatically updating the inverse
relationship? If I just call setProperty() then the inverse
relationship will get called. I had thought if I called
setPropertyRelationship() with
er.extensions.ERXEnterpriseObject.updateInverseRelationships=false I
would get the desired behavior, but it seems that
setPropertyRelationship() always updates the inverse relationship. For
example:
public void
setSetasideCodeRelationship(com.ods.wo.bids.db.SetasideCode value) {
if (_Bid.LOG.isDebugEnabled()) {
_Bid.LOG.debug(updating setasideCode from + setasideCode() +
to + value);
}
if
(er
.extensions
.eof
.ERXGenericRecord
.InverseRelationshipUpdater.updateInverseRelationships()) {
setSetasideCode(value);
}
else if (value == null) {
com.ods.wo.bids.db.SetasideCode oldValue = setasideCode();
if (oldValue != null) {
removeObjectFromBothSidesOfRelationshipWithKey(oldValue,
setasideCode);
}
} else {
addObjectToBothSidesOfRelationshipWithKey(value, setasideCode);
}
}
So even if
er.extensions.ERXEnterpriseObject.updateInverseRelationships is false
it still calls either addObjectsToBothSidesOfRelationshipWithKey() or
removeObjectFromBothSidesOfRelationshipWithKey(). Is this correct? If
so, is there a way to do this through the generated files?
Thanks,

I believe this will only update the inverse if you have the
er.extensions.ERXEnterpriseObject.updateInverseRelationships=true set.
Otherwise it should only call takeStoredValueForKey(aValue,
Property) and stop.

You have it backwards. The setPropertyRelationship() _explicitly_ sets
the inverse, and the updateInverseRelationship will have no effect on
it.
So, in short, if you want to have control over setting one side only
of a relationship, use either of the following _Without_ the
updateInverseRelationship=true:
takeStoredValueForKey(aValue, Key);
or
setProperty(aValue);

For example:
public void
setSetasideCodeRelationship(com.ods.wo.bids.db.SetasideCode value) {

_Bid.LOG.debug(updating setasideCode from + setasideCode()
+ to + value);

if (oldValue != null) {

Re: Inverse Relationships
currently not directly .. it's an all-or-nothing setting. you would
need to remove the inverse relationship from the model to turn it off.
you MIGHT be able to manually do a
_setUpdateInverseRelationships(false) (or whatever that method is
called) on the EO before you set the relationship in question, but
make sure you put the thing to turn it back on in a finally block.

Re: Inverse Relationships
Thanks. I was going to just remove the reverse relationship, but there
is actually a place where I do a query that uses the inverse
relationship. So my solution, which seems to work, is to remove the
class property flag for the inverse relationship. The only downside I
have come across is that there is then no ERXKey generated for that
inverse relationship.
Is there a way to have an ERXKey generated for a non-class property or
am I stuck adding it by hand?

Re: Can't get automatic inverse relationships to work
That's good to know. I can only assume that the old code was attempting to avoid an infinite loop. I SEEM to recall that the original code won't infinite loop, but it just wasn't optimal (you ended up doing it twice), so the conditional is just to choose a more optimal path. I think it already deals with the infinite loop inside of itself (since takeStoredValue is called by addObjToBothSides already). But it's been a while :) ms ___ Do not post admin requests to the list. They will be ignored.

Re: Can't get automatic inverse relationships to work
Uh... the whole point of the inverse relationship updating was that
you could say setAvatar() or addToAvatars() and if would update the
reverse for you? Since when is the code below needed now? I'd never
want a method that calls itself setFooRelationship as an extra to
setFoo().

Your underscore file for a to-one should look roughly like:
public er.attachment.model.ERAttachment avatar() {
return
(er.attachment.model.ERAttachment)storedValueForKey(avatar);
}
public void setAvatar(er.attachment.model.ERAttachment value) {
takeStoredValueForKey(value, avatar);
}
public void setAvatarRelationship(er.attachment.model.ERAttachment
value) {
if (_Person.LOG.isDebugEnabled()) {
_Person.LOG.debug(updating avatar from + avatar() + to +
value);
}
if
(er
.extensions
.eof
.ERXGenericRecord
.InverseRelationshipUpdater.updateInverseRelationships()) {
setAvatar(value);
}
else if (value == null) {
er.attachment.model.ERAttachment oldValue = avatar();
if (oldValue != null) {
removeObjectFromBothSidesOfRelationshipWithKey(oldValue,
avatar);
}
} else {
addObjectToBothSidesOfRelationshipWithKey(value, avatar);
}
}

When a set a one relationship from a form (without using the
setXXXRelationship) the relationship does not update on the other
side!
When using the setXXXRelationship it all works.
Am I missing something?

I'd never want a method that calls itself setFooRelationship as an extra to setFoo(). iPhone development is rotting your brain! :) But yes, I agree ... The problem he had is that he is using the old eogen templates that didn't even have a setAvatar(..) method generated. In the old templates there was ONLY a setAvatarRelationship method (which came from the way way back original templates that all of these were based on -- I forget who originally wrote it), which did an addObjectToBothSides. In the new ones, both methods are supported for backwards compatibility (I had thousands of lines of code that used the setXxxRelationship variant). In the new templates, if you call setXxxRelationship and you do not have inverse updating on, it will behave exactly as it did. If you call it when you DO have inverse relationship updating on, it will simply call through to the straight setXxx method, and in addition, you can just now simply call the setXxx method directly (and bind things to it) and it will do the right thing. So in the new way, you could completely remove your code that calls setXxxRelationship, and those methods could be deprecated. They're only still around to make it easier on people transitioning ... ms ___ Do not post admin requests to the list. They will be ignored.
