Re: Derived read-only attribute to expose PK [Was: Re: postgresql serial columns and wonder]
Hi Paul, derived attributes are computed by the database and thus those values are only updated when an eo is fetched into memory. In your case you are creating a new eo that has NULL for these attributes and as long as WO uses that eo or its snapshot cache those values will be still NULL. You have to refetch the eo to update the derived attributes. jw Am 03.10.2012 um 07:23 schrieb Paul Hoadley pa...@logicsquad.net: Hello, Just digging up this 2.5 year old thread...

The advantage is that the the new exposed column can be used in standard EOQualifier that works in memory and for schema-based qualifiers. Assuming your primary key col is named pk and you want an attribute named jobcode that exposes the pk... attribute: jobcode derived: √ read-only: √ definition: (pk) [Note: if mapping a column name to a derived attribute, you must surround it in brackets, otherwise EOF cannot parse it] I'm doing this in a model to expose the PK, as described. I have a D2W application that creates a new entity and saves it. Returning to the list page, the derived attribute shows _no value_ (the accessor returns null), even though the saved row is visible in the database, and obviously has a primary key. Logging out and back in does not fix this, though an app restart does—clearly not ideal for production. Is this expected, and thus should I be looking at modelling it some other way? (As an aside, last time I looked at this was a few months ago, and I swear it was behaving properly then—i.e., that the derived attribute was immediately visible.)

Re: Derived read-only attribute to expose PK [Was: Re: postgresql serial columns and wonder]
Hi Paul, FWIW, I made a small change to ERXGenericRecord (integration branch) recently that allows valueForKey( primaryKeyAttributeName ) to read the PK value using id or whatever you use for PK field names to be used. This was to allow a fetch qualifier qualified on the primary key attribute to be used in both fetchspecs and in-memory qualification. That might be a solution for what you are trying to achieve while avoiding the derived attribute altogether. -Kieran On Oct 3, 2012, at 4:34 AM, Paul Hoadley pa...@logicsquad.net wrote: Hi Johann, On 03/10/2012, at 5:26 PM, Johann Werner wrote: derived attributes are computed by the database and thus those values are only updated when an eo is fetched into memory.

Re: Jenkins and SVN+SSH
Le 2012-10-02 à 18:02, Roger Perryman ro...@xeotech.com a écrit : The following is just an update in case anyone stumbles upon this same problem. Not really a full solution but perhaps useful none the less. I was not able to get SVN+SSH in Jenkins to work on an OSX 10.6.7 system that otherwise can access the repository via command line and Eclipse. If I manually import the project it works fine but the defeats the purpose. I decided to upgrade Hudson to Jenkins on the original build server (OSX 10.5.8) that was throwing IndexOutOfBoundsExceptions, even though the actual compile was successful. I shut down Hudson (it was manually launched) and then installed Jenkins using the OSX package (as I did on the 10.6.7 system). I then created a test job and it worked fine. Then I created a simple test project and manually copied it into Jenkins. It worked fine. Next I added a project that was in SVN and configured it to use svn+ssh, entering my user name and supplying the private key (id_dsa). It worked the first time. I then entered the remaining jobs from the Hudson install into Jenkins. Everything _appeared_ to work. However, I am noticing that one of the projects fails to build because it cannot find some symbols from an included framework. These changes are new but they do show up in the Jenkins workspace for that framework. What I noticed is that the build.xml file in the referenced framework is different in the Jenkins version than it is in the Eclipse version. All the other projects have identical build.xml files. I've removed all of the build output but it doesn't seem to make a difference. Not sure where else to check. Another problem that I am having (on a separate project that does build successfully) is Archiving the artifacts. I've set up the post-build action using the config files from Hudson version (where it worked). It complains that the dist folder doesn't exist. Creating it did not solve the problem. There must be a part that I am missing that compresses the build output and copies it to the dist folder. In the files to archive field, I have XeoMed/dist/*.tar.gz. I want to get this step working before exploring the Publish over SSH plugin to automate pushing the build tarballs over to the deployment server. I will still manually install them but it should be a matter of just expanding a few files. Does anyone have a working example for this scenario? I don't have an answer for your problem, but for the Publish over SSH part, you can have a look at my wodeploy.pl script that will ship the archive of the app (and the archive of web server resources), decompress it, moving it to the correct location and restarting the app (or adding it to Monitor if the application don't exist). Thanks.

Did you do that? I submitted before fully answering the question. I generated a key (DSA) and placed the public key in authorized_keys2 on the server. This works AS ME. I supplied the private key to Jenkins so that it could establish a handshake with the server. I may need to add a Jenkins user on the SVN server otherwise, if I get this to work, I would get all the credit (or blame) for any activity from the build server. I think I have to let someone answer that who has experience specifically with svn+ssh on Jenkins... Maik ___ Do not post admin requests to the list. They will be ignored.
