[appengine-java] Re: Datastore.Text didn't work after deploy
Hi Ian,
thanks for your reply.
1. :-/
2. What is the difference?
3. Thats how i did it, yes.
Is there another way to story text with more than 500 letters? Simple
String won't work as far as I know.
Thanks

[appengine-java] Re: Datastore.Text didn't work after deploy
The Class for the datastore:
@PersistenceCapable
public class GuestbookEntry {
...
@persistent(defaultFetchGroup ="true")
private Text content;
...
}
Thats how I store it:
public void add(String title, String content) {
PersistenceManager pm = PMF().get().getPersistenceManager();
GuestbookEntry entry = new GuestbookEntry(title, content);
try {
pm.makePersistent(entry);
} finally {
pm.close();
}
}
Just how they described it in the appengine docs. As I say, it works
pretty fine in development and production mode locally. Am I missing
something?
It's like google appengine didn't know the class datastore.text, there
is a null value for the class type in the datastore viewer for the
field content.
Thanks for your help

Nope, that didn't solve the problem. Another strange thing is, when I query on the entities I only get one result on the appengine server, locally I get all results that are assigned to the user. Another strange thing is, that the datastore viewer in the appengine admin area shows a "null" value for the fields type.

Hi everyone, i've implemented a small application with ... @Persistent private Text content; ... When I test it locally and store this into the datastore everything works fine, when i deploy the app nothing get stored in that field "content". What am I doing wrong?

[appengine-java] Testing a remoteService that execute datastore operations
Hi everyone,
i want to test a remoteService that performs operations on a datastore
with jdo. For example:
public class UserServiceImpl extends RemoteServiceServlet implements
UserService {
public User addUser(User u) {
PersistenceManager pm = PMF.get().getPersistenceManager();
try {
pm.makePersistent(u);
} finally {
pm.close();
}
return u;
};
public User updateUser(User u) {
...
}
...
}
how can i implement a test case, that tests the listed operations, so
that the datastore operations didn't effect my development datastore
(maybe does some memcache operations or so?). I hope you get what i
mean :-) tell me if you need more information.
Thanks and greetings,
Poe

[appengine-java] Re: Confused by jdo relationships
Hi Ravi,
the relation is still a one to one relation because the
categoryGroupRelation holds a categoryId as a primary Key, so the
relation only holds one or zero categoryId for ever Category and
thereby every Category has only one CategoryGroup.
But my question is more about design principles. Isn't it better to
separate the data from relations? Lets say you create a User class on
the first Version of you App. You store thinks like eMail, names,
birthdays and so on in this class. In a second version of you App you
want to extend the database schema with user groups. By then you only
need to add two new classes Groups and UserGroupsRelations to
accomplish this and don't need to extends or alter the original User
class (Think about altering all the old User objects that are still in
the datastore, what are the inital values for this new attribute?).
There is another advantage: If you implement the userGroups relation
in the UserClass you only get all Users from one Group by making a
query over all Users insted of just checking the relations. You could
simply get allUsersFromAGroup and allGroupsFromAUser over this class.
Tell me how you would implement this and what are your experiences?
Thanks and greetings

[appengine-java] Re: Confused by jdo relationships
I've got a question regarding this.
Isn't it kind of "nicer" regarding the design to not store relational
Attributes in a core table/class. In the given example I would
implement this like this:
@PersistenceCapable
public class Categories
{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Long Id;
No owned or unowner object here
...
}
@PersistenceCapable
public class CategoryGroups
{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Long Id;
...
}
@PersistenceCapable
public class CategoryGroupRelation {
@PrimaryKey
@Persistent(mappedBy="category")
private Long categoryId;
@Persistent(mappedBy="categorygroups"
private Long categoryGroupId;
}
Isn't it better to design the tables this way? I don't like relational
attributes in a core database class. What do you think?

It seems that I've used my own Run Configuration where I included a wrong nucleus-appengine-something.jar in the classpath. When I added the Jar-File by hand the enhancer didn't work anymore. I created a new Run Configuration with the latest appengine version and it works. Are there some Documentation about how to set up the Developement Mode in the Run Configuration?
