how about linking this with the entity one as a complete documentation.
https://issues.apache.org/jira/browse/OFBIZ-1387

Or even better read and then add annotations/documentations that others
will read and maybe complete/enhance...
https://issues.apache.org/jira/browse/OFBIZ-1398
This part of the work, as for code, benefits to all but is more neglicted.
Because most people just read the DTD as Jonathon
suggested. Nevertheless having it as code-completion should motivates
everyone.

Skip,
Read the DTDs. See ${component:entity}/dtd/entitymodel.xsd .
For an entity, there are field, prim-key, relation, index.

Gads Adrian. I never knew of the existence of this tag. Thanks. It is
perfect. Someone needs to document it in the entity engine guide or at
least somewhere prominent. I just did a search for this tag and found
dozens of uses, but somehow, I missed it even though I looked at
OrderHeader's definition a gazillion times.
Are there any other cool undocumented DB features?

Why won't the index element work?

Ya BJ, seen that. What I want to do is create an index that is simply
used
for speed lookups. I do this now in postgres after install has been
done.
It would just be nice to be able to specify it in the entitydef file.
But,
it aint a big deal. Easily done manually in postgres.

It would be nice to have the foreign key checks as well as ways to
creating
indexes on non-key fields. There is a great performance increase having
an
index in some tables. Now I have to do in manually inside of the DB
which
is fine.

Subject: Re: Entity engine, many relations, foreign keys
Ah, wait. Note one more thing.
In entity PartyContactMechPurpose, there is supposed to be a type one
relation to
PartyContactMech. Why is it missing? We could have a field like
partyContactMechFromDate, so it
doesn't clash with fromDate. Same for thruDate. Of course, that
would
mean we cannot easily
change the fromDate field in PartyContactMech (unless we do EECA).
As it is now, it is possible to actually get PartyContactMechPurpose to
point to a non-existent
PartyContactMech. Just mix up the partyId and contactMechId such that no
such combination exists.
Advice? Or should we live without foreign key checks in such cases?

I found this from David Jones:
Foreign keys are done for type one relationships, not type many. A
type
many relationship is usually just the reverse direction of a type
one
relationship so the FK covers both.
What would it mean to have a foreign key on a type many
relationship?
Then a corresponding one relation will supply the foreign key
constraint?
What about a many-to-many relation? Look at entity PartyAttribute and
PartyTypeAttr for example. Is that a many-to-many? Looks odd, though. A
many-to-many usually requires a separate match-make table.
Is it correct to say that OFBiz does not do foreign key constraints
with
type many relations?
Do we have to insert an additional type one relation on field
attrName in order to get the foreign key constraints checks? But can
a
one relation be created without specifying the full primary key?
Looks like the type many relation is merely a convenient means to do
a
query like where attrName = whatever, so we can do a simple
getRelated().

Re: managing the size of console.log
$JAVA $VMARGS -jar ofbiz.jar $* /dev/null 21 means to append. means to write anew. Or, in short: $JAVA $VMARGS -jar ofbiz.jar $* /dev/null Listed twice because there are 2 pipes: standard output and error output. Both need to be sunk into /dev/null . The last tells OFBiz to run in the background, so you can log out of your shell and disconnect from the server without causing OFBiz to stop as well. Hope the above is right. Tired now late at night.
