Standalone Entity Modeler

[Hugi Thordarson]

Hi all.
Does anyone know how to build the Standalone Entity Modeler from the WOLips 
sources? Is the process documented somewhere?

Cheers,
- hugi

Exception for SQL generation with entity modeler: java.lang.RuntimeException: Failed to generate SQL

[Kwasi O-Ahoofe]

Another related, I think, exception/error associated with Entity Modeler/EOF 
implementation of WOLips;


Another Exception [from the Entity Modeler] to support my previous 
'difficulty'...:
java.lang.RuntimeException: Failed to generate SQL.

Ângelo, 

I added some debug output and I think I found the problem but have no solution 
yet... 

Activator.getDefault().log("IEOSQLGeneratorFactory object class : " + 
o.getClass().getName()); 
for (Class anInterface : o.getClass().getInterfaces()) { 
Activator.getDefault().log("interface : " + anInterface.getName()); 
} 
Activator.getDefault().log("IEOSQLGeneratorFactory object class Loader : " + 
o.getClass().getClassLoader()) 
Activator.getDefault().log("IEOSQLGeneratorFactory class Loader : " + 
IEOSQLGeneratorFactory.class.getClassLoader()); 

The output: 
!MESSAGE IEOSQLGeneratorFactory object class : 
org.objectstyle.wolips.eomodeler.core.sql.EOFSQLGeneratorFactory 
!MESSAGE interface : 
org.objectstyle.wolips.eomodeler.core.sql.IEOSQLGeneratorFactory 
!MESSAGE IEOSQLGeneratorFactory object class Loader :

So these are 2 different class objects from 2 class loader for the same class. 

Anyone know how to fix this ?

Re: Entity Modeler SQL generation exception

[Samuel Pelletier]

Thanks Wolfgang, the fix works.

This make me think the WOD editor problem may be similar, we have an NPE but I 
suspect the real problem occur when the editor try to create the special view 
when the .wod file is absent or when the wod view is too small.

Re: Entity Modeler SQL generation exception

[Ângelo Andrade Cirino]

Hi Wolfy, I guessed the issue could be solved editing the configuration files 
as you did, but I used your commit and it raised another problem:

org.objectstyle.wolips.eomodeler.core.model.EOModelException: There was more 
than one SQL generator factory defined.

Hi Samuel, Wolfy seems to have solved the bug. I will create a branch in my 
repo and will report back.

Re: Entity Modeler SQL generation exception

[Samuel Pelletier]

Ângelo,

I added some debug output and I think I found the problem but have no solution 
yet...

Activator.getDefault().log("IEOSQLGeneratorFactory object class : " + 
o.getClass().getName());
for (Class anInterface : o.getClass().getInterfaces()) {
Activator.getDefault().log("interface : " + 
anInterface.getName());
} 
Activator.getDefault().log("IEOSQLGeneratorFactory object class Loader 
: " + o.getClass().getClassLoader())
Activator.getDefault().log("IEOSQLGeneratorFactory class Loader : " + 
IEOSQLGeneratorFactory.class.getClassLoader());

The output:
!MESSAGE IEOSQLGeneratorFactory object class : 
org.objectstyle.wolips.eomodeler.core.sql.EOFSQLGeneratorFactory
!MESSAGE interface : 
org.objectstyle.wolips.eomodeler.core.sql.IEOSQLGeneratorFactory
!MESSAGE IEOSQLGeneratorFactory object class Loader : 
org.eclipse.osgi.internal.loader.EquinoxClassLoader@289c2793[org.objectstyle.wolips.eomodeler.eclipse:4.4.20150506.01(id=1470)]
!MESSAGE IEOSQLGeneratorFactory class Loader : 
org.eclipse.osgi.internal.loader.EquinoxClassLoader@2dcbf825[org.objectstyle.wolips.eomodeler.core:4.4.20150506.01(id=1469)]

So these are 2 different class objects from 2 class loader for the same class.

Anyone know how to fix this ?

Samuel

Re: Entity Modeler SQL generation exception

[Ângelo Andrade Cirino]

In IEOSQLGeneratorFactory.java I made this

Object o = configurationElement.createExecutableExtension("class");
System.out.println("object class : " + o.getClass().getName());
IEOClassLoaderFactory classLoaderFactory = (IEOClassLoaderFactory) o;

And got this output

object class : 
org.objectstyle.wolips.eomodeler.eclipse.EclipseEOModelGroupFactory

The returned class is neither EOFSQLGeneratorFactory nor IEOSQLGeneratorFactory

Re: Entity Modeler SQL generation exception

[Samuel Pelletier]

I also get the same error. I modified a plugin.xml file that seemed incorrect 
and now I have this one:

java.lang.ClassCastException: 
org.objectstyle.wolips.eomodeler.core.sql.EOFSQLGeneratorFactory cannot be cast 
to org.objectstyle.wolips.eomodeler.core.sql.IEOSQLGeneratorFactory

at java.lang.Thread.run(Thread.java:745)

I do not understand how it is possible; EOFSQLGeneratorFactory implements 
IEOSQLGeneratorFactory !

public class EOFSQLGeneratorFactory implements IEOSQLGeneratorFactory {
...
}

Ângelo Andrade Cirino posted this on April 29, I think there is something here, 
some sort or dependency or class path missing during the plugin execution.

If I return that to EOEclipseClassLoaderFactory, I crash with a classnotfound

Entity Modeler SQL generation exception

[Ângelo Andrade Cirino]

This is the exception I got when debugging WOLips 4.4

java.lang.ClassCastException: 
org.objectstyle.wolips.eomodeler.eclipse.EclipseEOModelGroupFactory cannot be 
cast to org.objectstyle.wolips.eomodeler.core.model.IEOClassLoaderFactory

This issue is beyond my little knowledge of WOLips.

Re: Entity Modeler exception when trying to generate SQL

[Ângelo Andrade Cirino]

I’ve resorted to migrations, but then I had to fix a lot of things to get 
migrations working properly.

Fixing this issue of SQL generation demands knowledge of Eclipse plug-in 
development that I lack and, from the code I inspected trying to debug the 
issue, seems very hard to grasp in a short period. I am willing to help if some 
guidance is given.

Re: Entity Modeler exception when trying to generate SQL

[Ken Anderson]

Has anyone made any progress on this?  If not, can anyone point me to resources 
that would help me be able to develop/debug this?

Thanks,
Ken

Re: Entity Modeler exception when trying to generate SQL

[Ângelo Andrade Cirino]

Some more light on the issue. This is the first time I debug WOLips and I have 
never attempted to change the code. That said, when debugging Entity Modeler I 
was able to locate this exception thrown just before the exception I originally 
reported was thrown:

org.eclipse.core.runtime.CoreException: Plug-in 
org.objectstyle.wolips.eomodeler.eclipse was unable to load class 
org.objectstyle.wolips.eomodeler.core.sql.EOFSQLGeneratorFactory.

Really?! Your self-compiled is also 4.4? Let’s work together on figuring out

Re: Entity Modeler exception when trying to generate SQL

[Hugi Thordarson]

I get this same error whenever attempting to generate SQL from Modeler. 
Happened after upgrading to WOLips from the new 4.4 repository, returning to my 
previous configuration (self compiled WOLips plugin) still works fine.

Cheers,

Entity Modeler exception when trying to generate SQL

[Ângelo Andrade Cirino]

Hi all,

I’ve setup FrontBase as my development database server and am using Eclipse 
4.4.2 and WOLips 4.4. When I try to generate SQL or reverse engineer a database 
I get the following exception:

java.lang.ClassCastException:

to org.objectstyle.wolips.eomodeler.core.sql.IEOSQLGeneratorFactory

Any clues?

This sounds like a build path issue.  Either the MySQL plugin is not

I have a working project and just basically moved to a new 
workstation and copied my Eclipse and Wolips configuration.

Then... Entity Modeler greeted me with this error.
I decided to have a fresh install using the same eclipse 
3.7(Indigo) and wolips: 
http://jenkins.wocommunity.org/job/WOLips37Stable/lastSuccessfulBuild/artifact/temp/dist/

Same error.

I googled and actually found just 1 related(actually, the same 
problem) problem:

http://objectstyle.org/woproject/lists/woproject-dev/2006/10/0148.html
Can anyone point me to the right direction?

Thanks in advance.

What about your connection dictionary?  Where was that set on the old machine?

Entity Modeler - SQL Generation Error

Just wondering if anyone have ever encountered this error in Entity 
Modeler - SQL Generation.

Here is the stacktrace:

Entity Modeler standalone

[Aaron Rosenzweig]

Hi WOrriors,

I’ve put a freshly built pure java stand-alone EntityModeler here for the 
moment:

https://www.dropbox.com/s/npu2gx3b060j2sa/Entity%20Modeler_April_24_2014.zip

But before you get excited, read on… 

Dave Avendasora cued me in to pure java app version of Entity Modeler that was 
created ages ago by some people in the WOCommunity. He had it stashed away like 
a treasured gem scavenged from a pharaoh’s tomb.

Dave passed it to me and I tried it out. It wouldn’t open the primary EOModel 
file in our biggest app. It got stuck on “Please Wait” and cpu was idle. I had 
to force quit. 

After installing a “delta pack”, etc. for Eclipse and looking at the WOLips 
source tree I see that there is a way to build it standalone. What it creates 
is a streamlined version of Eclipse with only the Entity Modeler bits and a 
custom UI. For all intents and purposes it’s a pure java app. A pure java 
standalone Entity Modeler.

So I did just that, right now, after a bit of futzing it is now a 
double-clickable app. It also opens that EOModel file that Dave’s old version 
could not. I started to get excited...

Unfortunately I don’t see it as being truly useful for the following reasons:

1) It won’t let you make a “Model Group” file.

2) It doesn’t appear to have any sense of your project tree which leads to the 
additional issues below

3) It won’t find your Prototypes. I believe the original Apple Cocoa app with 
the Objective-C-Java-bridge relied on the .pbxProj file to find the Prototypes. 
I have no idea if this java app looks for anything like a build.xml file but I 
can’t get it to find our prototypes. 

4) It won’t find other Entity Model files in your app, it can only open one at 
a time. 

Perhaps that’s why it’s obscure… I previously never even knew this app existed… 
it’s close but not quite usable. I was hoping it would be a “go to app” that 
would always work for modifying models, reverse engineering, and generating SQL 
tables but, alas, it’s not that today. 

If anyone wants to download and play with it please do. If you have other ideas 
or want to maybe push it further it might be doable but the Eclipse stuff seems 
like a quagmire I want to sidestep. If you think it is useful as is, please 
post it to WOCommunity for others to use.

Re: Entity Modeler ?

[Aaron Rosenzweig]

Hi Ted,

Cool. Glad that worked for you :-) There’s no way for you to have known… you 
have to be a dinosaur. Once upon a time there was a “backspace” and a “delete” 
key. They are different. Now, on most Mac keyboards, you only have a 
“backspace” key but it is labeled as “delete.” And that Entity modeler is only 
coded up for a “true” delete. To emulate a true “delete” you do fn-backspace.

Cheers,
AARON ROSENZWEIG / Chat 'n Bike

Re: Entity Modeler ?

[Theodore Petrosky]

I just tried it on my Laptop (not the full sized keyboard). 

I selected the default that existed and held a shift-fn delete. and the 
Userinfo was deleted. I would never have guessed the function key.

there you go Jean Pierre and David

Re: Entity Modeler ?

[Aaron Rosenzweig]

Hi Ted and others,

The answer is:

fn-delete

That is, you hit the “function key” on your Mac laptop which is labelled “fn” 
and is to the bottom left of the keyboard and then while it is pressed you hit 
the backspace key which is often labelled “delete” these days or “backspace” on 
older keyboards. 

This will blow away things in the User Info.

If you have a full keyboard (not a laptop) then there is a dedicated delete 
key. If you use a word processor it is that other key that stays in one spot 
buts starts sucking text into itself.

I guess that was clear as mud...

Cheers,
AARON ROSENZWEIG / Chat 'n Bike

Re: Entity Modeler ?

[David LeBer]

Conversely,

1. In WOLips, ctrl click on the EO model, choose Show in -> Navigator
(switches to navigator view)
2. Click the disclosure triangle beside the EO model
3. Click the Entity.plist you are interested in.

You can configure Eclipse’s file associations to open .plist files in the local 
text editor or an external one if you wish.

Re: Entity Modeler ?

[Theodore Petrosky]

My solution is to navigate in the finder to the .eomodeld file. This actually 
shows up as a folder. In there are all the .plist files for the model. 

I make sure I quit Entity Modeler (I don't know if there is an issue with 
accessing the .plist while both Entity Modeler and my text editor are looking 
at the file so I quit Entity Modeler), open the plist in my text editor 
(TextWrangler) and delete the userInfo = {"" = ""; }; line.

Not elegant, but it works. BTW, I just tried it with both the text editor and 
Entity Modeler running. Entity Modeler doesn't see the change until I quit and 
relaunched.

Entity Modeler ?

I am starting a new project and I thought I would learn some new stuff.

If one adds a default the User Info section, what is the correct way to delete 
it? I tried in Entity Modeler but it leaves kaka behind. My solution was to 
open the .plist and delete the userinfo = {}  line.

am i missing something in Entity Modeler?

Re: Entity Modeler, String rtrim not trimming?

[gsbrown]

I think I got it.

Java string trim does trim whitespace at the beginning or ending of a
string.

erprototypes trim is more a lack of padding spaces to fit a fixed width
character db field when strings are coming out or into a db.

A varchar really doesn't need padding, so a rtrim may not do much with
a varchar. (Which is what I am seeing, I think.)

A string also may be truncated to fit in a too small db field; here a
varchar may be trimmed to fit.

Where's that caffeine?

Re: Entity Modeler, attributes default value for migrations

[Theodore Petrosky]

But here is the gotcha!

in Entity Modeler (or hand editing the plist file) you must use 

userInfo = {default = 0; };

note the zero NOT false!!

if you use 'false' or 'true', EM creates the migrations okay, however creating 
a new object in D2W throws errors:


Apr 19 18:05:52 ASBriefsD2W[57541] WARN  NSLog  - 
: Exception 
occurred while handling request:
java.lang.NumberFormatException
[2012-4-19 18:5:52 EDT]  java.lang.NumberFormatException
at java.math.BigDecimal.(BigDecimal.java:459)
at java.math.BigDecimal.(BigDecimal.java:728)

so the userInfo = {default = 0; };

thank you John for pointing out the zero.

Ted

Re: Entity Modeler, attributes default value for migrations

I didn't understand 'edit manually' until I used Chuck's method of adding a 
"User Info" entry in Entity Modeler. Then I used TextMate on the plist and 
understood.
Thanks,

You have to add it manually into the userInfo dictionary by editing by model 
with a text editor.  For example, for the ATTRIBUTE called "deleted":
...        {            columnName = "scp_deleted"; 
            name = deleted;             prototypeName = intBoolean;             
userInfo = {default = 0; };             width = 1;         }...

problem is that if I go back and alter the schema and recreate the migration, I 
must remember to add in the default selector(s).



I don't see in EM where I could put in a default value (or I am blind).



Is there a place to put in a default value in Entity Modeler so the migrations 
it creates include the default value?

Re: Entity Modeler, attributes default value for migrations

[Theodore Petrosky]

that was so intuitive that I can not believe I didn't just stumble across it. 
It creates a little weird syntax. I was expecting:

creativeBriefTable.newFlagBooleanColumn("isfiled", false, false);

what i got was:

creativeBriefTable.newFlagBooleanColumn("isfiled", false, 
er.extensions.foundation.ERXValueUtilities.booleanValue("false"));

Obviously, it is just fine, just a little wordy.

Thank you,

Ted

Re: Entity Modeler, attributes default value for migrations

[Chuck Hill]

Hand edit?  Eeew!   :-P

Select the property and then the User Info tab in the Properties inspector.  
Click where it says (0 items) and hit Enter.  Edit the name and value.

Re: Entity Modeler, attributes default value for migrations

[Theodore Petrosky]

No not really,
I create a model that has an attribute (an intBoolean) called isFiled. I ask 
Entity Modeler to create the migrations for me and it gives me:


@Override
public void upgrade(EOEditingContext editingContext, ERXMigrationDatabase 
database) throws Throwable {


ERXMigrationTable creativeBriefTable = 
database.newTableNamed("creativebrief");
creativeBriefTable.newIntegerColumn("id", false);
creativeBriefTable.newFlagBooleanColumn("isfiled", false);
creativeBriefTable.newLargeStringColumn("jobnumber", true); 
creativeBriefTable.create();creativeBriefTable.setPrimaryKey("id");}
notice it created:
creativeBriefTable.newFlagBooleanColumn("isfiled", false);
except I need:
creativeBriefTable.newFlagBooleanColumn("isfiled", false, false);
the last property is the 'default' value.
from psql:
isfiled    | boolean | not null default false
it is no big deal except in the design stage of a database. if I mess with the 
schema and recreate the migrations, I have to remember which attributes I 
created default values for.
I was hoping there was a box in Entity Modeler that said, "Default Value".

there are two signatures for newFlagBooleanColumn
newFlagBooleanColumn(name, allowNull)newFlagBooleanColumn(name, allowNull, 
defalutValue)
newIntegerColumn is the same (two signatures)

Hi Ted,
You can use EOF to set your values in migrations, so I guess you could set your 
default values in your entity? 
See Mike's example app SecretPal and the SecretPal0 migration postUpgrade 
method. That might give you what you are looking for.
Also just recently someone (Ramsey?) posted that you can put default values in 
your User Info Dictionary for the entity.
Before I found out about this approach I was using direct SQL statements (which 
means that the migration may/will break across databases, so Mike's method is 
better if you can do it).
  @Override  public void upgrade(EOEditingContext editingContext, 
ERXMigrationDatabase database) throws Throwable {    
ERXJDBCUtilities.executeUpdate(database.adaptorChannel(), "INSERT INTO Role 
(roleDescription,id) VALUES ('Admin',1)", true);  }
Is this what you're after?

Re: Entity Modeler, attributes default value for migrations

[John Huss]

You have to add it manually into the userInfo dictionary by editing by
model with a text editor.  For example, for the ATTRIBUTE called "deleted":

...
{
columnName = "scp_deleted";
name = deleted;
prototypeName = intBoolean;
*userInfo = {default = 0; };*
width = 1;
}
...

Entity Modeler, attributes default value for migrations

[Theodore Petrosky]

When I create an attribute in Entity Modeler, and create the migrations, it 
does a beautiful job.

creativeBriefTable.newFlagBooleanColumn("isfiled", false);

and I know I can add a default value here

creativeBriefTable.newFlagBooleanColumn("isfiled", false, false);

problem is that if I go back and alter the schema and recreate the migration, I 
must remember to add in the default selector(s).

I don't see in EM where I could put in a default value (or I am blind).

Is there a place to put in a default value in Entity Modeler so the migrations 
it creates include the default value?

Prototypes don't load from ERPrototypes in Entity Modeler when building with maven

[Faizel Dakri]

Have any maven users out there seen a problem with prototypes not showing up in 
Entity Modeler? I've got a project with an eomodel that has a dependency on 
ERPrototypes, but when I open the model in Entity Modeler, all of the 
prototypes seem to disappear. Searching through the archives revealed a similar 
issue a few years back, but it looked like it had been fixed with a WOLips 
update. 

I don't have any of the wonder frameworks open as projects in Eclipse, so 
they're all resolved from my local maven repository. When I examine 
ERPrototypes-5.4-SNAPSHOT.jar, I can see the erprototypes.eomodeld resource, 
along with the various db prototype entities. I can also run my app from 
Eclipse and it is able to find the prototypes just fine. It's just when I'm in 
Entity Modeler that I'm having issues.

I'm currently running Eclipse 3.7.1 with WOLips 3.7.10096.

Anyone else seen anything like this?

Thanks,

F

ERAttributeExtension "just" makes it easier (or possible) to use the Factory 
Method: / Conversion Method: stuff in EOF:

The EOAttribute class allows you to model an attribute for a java object. In 
order to do this, the java class must implement a custom conversion method to 
write the value into the database and a value factory method to read the object 
back out. In some cases, you may want to use a java class as an attribute which 
does not implement a method appropriate for these operations. In some cases, 
the java class may even befinal making it impossible to model the class as a 
custom attribute.

The ERAttributeExtension framework is designed to solve this problem. It does 
so by reimplementing EOAttribute. The reimplemented EOAttribute fixes the 
broken implementation of WO 5.4.3's adaptorValueConversionClassName 
characteristic and adds a new valueFactoryClassName characteristic to 
EOAttribute. Therefore, any prototype attribute which uses one of these two 
attribute characteristics in ERPrototypes requires the inclusion of this 
framework to work properly.

+1

If you store it in a binary format, how you are going to query on it?  How will 
you access it from outside of EOF?

Re: Entity Modeler and java.io.Serialization

[John Huss]

If you use the ERAttributeExtension framework or whatever it's called I think 
could do it - this is what the joda time prototypes use.  It fixes the features 
that were supposed to be in 5.4

But I'm not sure why you would want to store it in a binary format; if you just 
need to convert a stored string to an InetAddress there probably an easier way, 
like modifying your EO templates.

No.  :-)

Kieran has a related blog post: 
http://homepage.mac.com/kelleherk/iblog/C729512539/E2033071041/index.html

The summary is that EOF provides for non-Java serialization using these 
attribute properties set in Entity Modeler:
Class:
Factory Method::
Conversion Method:
Init Argument:

You may get this to work by using getByName as the factory method and 
getHostName as the conversion method.  Otherwise you need to wrap classes like 
this to serialize and de-serialize using this method OR somehow change EOF to 
do other serialization (probably possible, probably not easy).

Because that is only for the custom serialization as above.

Patches welcome.  :-)

Entity Modeler is setup to support what EOF expects which is not what you plan. 
 The com.webobjects.jdbcadaptor.JDBCPlugIn class is one place to start looking 
if you want to try modifying EOF.

Entity Modeler and java.io.Serialization

[Riccardo De Menna]

Hi there,

Is there a way to force the db adaptor to serialize and deserialize objects 
using java.io.Serializable?
To put it in other words, is there an easy way to serialize simple java objects 
without the need to write customized code?

For example, I was tweaking some of my prototypes and I just realized that it 
would be very useful to have an inetAddress prototype for all ip/host 
addresses. The class for it is java.net.InetAddress and it obviously already 
implements Serializable. Can I leverage that in entity modeler to save and 
restore those objects to blobs without having to write a serialization utility?

Also, why is the "class" field always disabled in entity modeler when the 
"value class" is visible? If there is no automatic way to deserializae using 
Serializable, then I was thinking of writing a custom serialization class.
I though I could use the "class" field to point to my deserialization class, 
the "value class" field to tell the system what to expect as a final output, 
and the "value type" field to help my class decide "how" to deserialize. But 
the class field is always grayed out and disabled and I can't find any 
documentation on how I would have to write my code.

Comments appreciated…

[workaround]: Re: SQL generation problem with Entity Modeler

[Lars Sonchocky-Helldorf]

I found a workaround for my problem: I created a new Eclipse workspace and 
imported only the framework which contains the EOModels. Then I can create the 
SQL without problems. This works without the other projects from which the 
framework projects depends because those are in a compiled form in my local .m2 
Maven repository. This is the case because I did a mvn install in the other 
workspace before.

cheers,

Lars

SQL generation problem with Entity Modeler

[Lars Sonchocky-Helldorf]

Hi,

I had this problem before. But I got no answer then: 
http://permalink.gmane.org/gmane.comp.web.webobjects.woproject.devel/16073

The situation here is the same, the Maven project tree consist out of a 
structure like this:

JvMAll
|
\-Applications
| |
| \-ApplicationA
| |
| \-ApplicationB
| |
| .
| .
| .
|
\-Frameworks
  |
  \-FrameworkA
  |
  \-FrameworkEO
  |
  \-FrameworkB
  |
  .
  .
  .

the EOModel in question resides inside the resources folder of one of the 
Framework projects, let's say inside 'FrameworkEO'. Only JvMAll, the 
'Applications'-folder subdirectories and the 'Frameworks'-folder subdirectories 
are actually Eclipse projects (not the 'Applications' and the 'Frameworks' 
folder itself).

No I can open one of the several EOModels inside the 'FrameworkEO' projekt and 
edit it without any problems. Only when I try to generate SQL from the model I 
get:


Failed to create EOF class loader. Launch configuration Entity Modeler SQL 
Generation references non-existing project JvMAll.

... 5 more

Closing the JvMAll umbrella project (which I use only for building, 
synchronizing and committing to the VCS (CVS this time actually :-( )) makes 
the situation only worse. 


Has somebody any clue what to do?


thanks,

Lars

Re: entity modeler settings?

So, 

someone's version has a need for these.
someone has this version (but not me).

Is there a reason why I would like the afore mentioned version more (or less) 
than the version that is generally downloaded with the current Entity Modeler?

As this is a 'Secret' version (I feel the orchestra building), can I play too? 
and 

What other features that I wouldn't like or need are there?

I hope my curiosity doesn't bring on an investigation from Homeland Security.

this is in the category of things i'm less likely to fix in wonder ... doing

I don't think anything has changed since then.  IIRC (and it has been a while 
now), from "peeking" it appeared that even part inside of WO was incomplete.  
It would be a good thing to fix in Wonder.

i don't think FB does it either ... if entity modeler just called the 5.4

Re: UNIQUE constraint on Entity Modeler

[Mike Schrag]

the bigger issue is that the 5.3 and 5.4 schema generation API's aren't 
compatible, so if you use the 5.3 API's, you hit these weird API paths that 
bypass certain features. it's kind of a mess. currently migrations and entity 
modeler both use the 5.3 API's. now that we have a 5.4 branch, we can actually 
call through the 5.4 API's and these features can be turned on.

Re: UNIQUE constraint on Entity Modeler

[Kieran Kelleher]

I am guessing is needs to be implemented in the appropriate db platform plugin 
or SQLHelper class in Wonder. it is probably implemented in FB since that 
probably would have been what Mike S was using when he added that feature.

EOEntityIndex is new in 5.4.x and would require plugin support for it  
to work.  I assume that is at least one of the reasons why it does not  
work with Wonder's Postgres plugin.  When I asked on list about this

Constraint setting on the index can then be set to 'Distinct' (which I assume

UNIQUE constraint on Entity Modeler

Hi!

  I had the idea I saw, in some W(O)W(O)DC, someone talking about having a 
"unique" checkbox on Entity Modeler for a property. That would make the 
generated SQL have the UNIQUE constraint to the DB.

  Did I dream about this, or is it real? I can not find it anywhere.

Yes, you can delete it.

Re: EOPrototype in Entity Modeler question

[Ricardo J. Parada]

On Oct 29, 2009, at 5:39 PM, Mike Schrag wrote:

oh wait ... you're going from no prototype to a prototype.  yeah i'm  
not sure it will remove those -- as far as it knows you have an  
override of those values. this has been a debate i've had with  
myself for a while (and i think with the list a couple years ago,  
too), whether if you set a prototype, should it automatically  
replace every prototyped value in the attribute. the reason i have  
avoided this is that i tend to not implement features that LOSE  
information. however, it's debatable in this case what your intent  
actually IS -- if you set a prototype, PROBABLY you mean you want  
all the settings of the prototype applied. This gets a lot hazier,  
though, if you're talking about the width of a string -- if you  
change from one string prototype to another, did you intend to blow  
away the width?  maybe only on the ones that explicitly set a width,  
i guess?


That makes total sense.  :-)

In my original email I was looking for a way to clear all the values  
so that there are no overrides and then set the prototype.  So that's  
really a feature request.  But I'm handling it manually right  
now.  :-)   I can live with that.  I use subclipse's Team Synchronize  
view to see these things and clean them up.


anyway, i'm not SURE that's what you're seeing but I suspect it is.   
is valueClassName being removed at least?  i don't test much going  
from no prototype to a prototype, so i'm sure there are weird edge  
cases of this.




Yes, valueClassName is being removed!

By the way, how does the Data Type chosen for an attribute affect me?   
For example, I see different options related to dates / times: i.e.  
Date, Date (MSSQL), Time, Timestamp.  For new attributes I just leave  
that with the default once I pick the prototype (either date or  
dateTime).  But for existing attributes where I have the Data Type  
already selected and then choose a prototype I'm not sure how changing  
Data Type would affect me.


For example, if my existing attribute named "creationDateTime" had a  
Data Type of Timestamp selected and no prototype. And then I set the  
prototype to dateTime and change the Data Type to Date.  Will that  
affect me somehow?  :-)




Thanks,
Ricardo

Re: EOPrototype in Entity Modeler question

[Mike Schrag]

strange ... i'll have to look into that. i run it on snow leopard  
without any problems.


if you're not using eclipse 3.5, then you can just manually remove  
those valueClassnames. or grab a 3.5 install just to open up EM once  
in it and it will fix those.

Re: EOPrototype in Entity Modeler question

[Ricardo J. Parada]

I'm on Eclipse 3.4 and WOLips nightly.  It's actually lots of eomodels  
that I'm converting to use prototypes.  I'm affraid to use the Entity  
Modeler.app as there are lots of cross-model relationships and may  
have to do additional work to get it to see all my models.  But if  
that will make it easier to update my attributes to use prototype  
attributes then I can go that route.  :-)


Thanks,
Ricardo

Dear WebObjects Team:

I installed the full Eclipse+WOLips turn key installer today. When I launch the 
Entity Modeler application and try to create a new model, I get the following 
error (after choosing a folder): General Failure, Creating empty EOModelGroup 
for this model because null NullPointerException. Opening an existing EOModel 
gives me a similar error. (OS X 10.5.8 Intel)

Is there something else I need to do to set up the application? Thank you,

Tavis McDevitt

Thanks David,

This is exactly what I was looking for.

I will try it.

Gracias.

Hi, Thanks for the hint about using Prototypes, it is really useful.


That brought to my mine a questing that is a little out of the topic.

If you have an attribute prototyped as currencyAmount the precision  
is set to 38 and the scale to 4. The Data Type suggested is  
java.math.BigDecimal.
How are you guys controlling that the BigDecimal in your java class  
does not have a value whit a scale superior of 4 before saving the  
editing context to avoid an exception?


We are currently solving this just rounding the value before  
saving, or in the validation method  to ensure the scale is not  
superior that the value defined in modeler. But one of the great  
things of prototyping is that if for some reason I want to change  
the scale to 5 instead 4, all the attribute definition's that are  
using that prototype will be updated, what about the BigDecimal?


Maybe I am wrong on thinking that I should be sure that the scale  
of my BigDecimal  must be less than or equals to the scale defined  
in the modeler to avoid exception on saving.


How do you guys handle this?


I have modified my EOGenerator _Entity.java template to watch for  
BigDecimal data types and to automatically set the scale to what the  
Model has the scale set to. Here's the snippit of code from the  
attribute setter method:


#if ($attribute.javaClassName == "java.math.BigDecimal")
if (${attribute.name} != null) {
			${attribute.name} = ${attribute.name}.setScale($ 
{attribute.scale}, RoundingMode.HALF_UP);

}
#end

I never had an error since I started using this and if I change the  
settings in the EOModel, my classes are updated when the  
EOGeneration runs.

Why don't you just choose the most obvious prototype: 'id'? Life

Thank you,

Otherwise, you should be able to just select one entity at a  
time and click the SQL button and see which one(s) generate the  
error. I see pretty clear error messages with this, that say  
exactly what external type is not recognized.

Here's what the code looks like based on the default templates since  
they use "value" instead of the actual attribute name:


#if ($attribute.javaClassName == "java.math.BigDecimal")
if (value != null) {
value = value.setScale(${attribute.scale}, 
RoundingMode.HALF_UP);

I guess this is where Kieran's solution of using ERXModel so you can  
override the ERPrototypes default of "integer" would fit in if you  
think you'll need keys > 2147483647. Two billion is a lot, but not a  
completely unreasonable quantity.

Thank you,

Otherwise, you should be able to just select one entity at a time  
and click the SQL button and see which one(s) generate the error. I  
see pretty clear error messages with this, that say exactly what  
external type is not recognized.

Re: WOLips Entity Modeler SQL Generation and WO 5.4

[Kieran Kelleher]

 and if you want even more modern 'fanciness', you can turn on  
ERXModel as your eomodel class in Wonder, you can have custom  
prototypes of your own in other eomodel files and with the right  
naming convention (of the eomodel file) and using the same prototype  
attribute name, you "override" the built in prototypes with your own  
custom definitions. useful for the BigDecimal scales etc. :-;


See ERXModel api (or source) for more details.

Regards, Kieran

Well, if you're looking for excuses to "upgrade" things, maybe  
transition to using Prototypes. I'm sure the Postgress Prototypes  
in Wonder's ERPrototypes will all have the proper External  
Types. :-)


Wow, thank you Dave, that DOES make things substantially easier
(and less prone to error--sure enough, had a missing external type in
one of the entities).  All this modern fanciness, still getting used
to it...

Now my question is, for the Postgresql prototypes, which one
is recommended to use for primary keys?  Googling reveals some people
using long (called longNumber in prototypes), which is what I  
historically
used, while others are using varchar (but not consistent regarding  
size:

10? 100? 10,000,000?  :-))


Why don't you just choose the most obvious prototype: 'id'? Life can  
be so easy ;-)
