I have been fumbling with this for a while.
I made a reader reload to reload exported data as a transfer ability. so my question, from the architects. is there a sequence of all the entities that will allow them to load? |

There have been approximately 2000 mailing list messages on this topic. A single ordered list of entities by foreign key dependencies is impossible, there are loops in them. If you want to research theory on this check out graph traversal algorithms and the like. Use one of the various tools to get around FKs, like dummy fks or the check/update database page that has tools to turn them on/off. -David smime.p7s (3K) Download Attachment |
I did check my ML from 2005 to now before writing this.
did try the current webtools import feature as well. will read up on thegraph traversal algorithms David E Jones sent the following on 11/26/2007 8:04 PM: > > On Nov 26, 2007, at 8:58 PM, BJ Freeman wrote: > >> I have been fumbling with this for a while. >> I made a reader reload to reload exported data as a transfer ability. >> >> so my question, from the architects. >> is there a sequence of all the entities that will allow them to load? > > There have been approximately 2000 mailing list messages on this topic. > > A single ordered list of entities by foreign key dependencies is > impossible, there are loops in them.

The point of the graph traversal is that they are NOT a solution (but rather proof that there is no solution down that road). That's why we have the other two things I mentioned. -David On Nov 26, 2007, at 9:23 PM, BJ Freeman wrote: > I did check my ML from 2005 to now before writing this. > did try the current webtools import feature as well. > will read up on thegraph traversal algorithms > > David E Jones sent the following on 11/26/2007 8:04 PM: >> >> On Nov 26, 2007, at 8:58 PM, BJ Freeman wrote: >> >>> I have been fumbling with this for a while. >>> I made a reader reload to reload exported data as a transfer >>> ability. >>> >>> so my question, from the architects. >>> is there a sequence of all the entities that will allow them to >>> load? >> >> There have been approximately 2000 mailing list messages on this >> topic. >> >> A single ordered list of entities by foreign key dependencies is >> impossible, there are loops in them.

It was April 2007. https://issues.apache.org/jira/browse/OFBIZ-897 comes close at least with the data model at that time... there may have been a condition or two that remained to be worked out. It completed what I needed at the time, so I didn't polish it any further.

This one may have had something to do with it too.... https://issues.apache.org/jira/browse/OFBIZ-810

what gets me, is that after 15 iterations, it there are still conditions
that keep the other files from loading. you would think that with the PK off and/or dummied that atleast it would match up again.
