Re: Saving NSDictionary to DB
See NSPropertyListSerialization. There should be examples in Wonder and maybe support for using it.

Re: Saving NSDictionary to DB
you can serialize it into a property list string and back. there may even be a “transformable” on the modeler, I can’t recall but likely you can write a transformer to read and write to and from a string which would work just fine I think. make sense?

Re: Saving NSDictionary to DB
Chuck - stop typing so fast… :) To add to Chuck’s response, you can serialize to XML: String xml = NSPropertyListSerialization.xmlStringFromPropertyList(dictionary, false); but then there ARE Wonder additions: NSData info = er.extensions.foundation.ERXPropertyListSerialization.dataFromPropertyList(dictionary, er.extensions.foundation.ERXPropertyListSerialization.PListFormat.NSPropertyListBinaryFormat_v1_0, null); The first could be stored in a large database string, the second could be stored in a blob.

RE: Saving NSDictionary to DB
Hi Jessie,I can see in the EntityModeler a prototype mutableDictionary.Basically has a external type bytea, and a custom data type ERXMutableDictionary with factory method fromBlob and conversion method toBlob.I'm going to try with that.

Re: Saving NSDictionary to DB
Here is how I implemented such attribute:
{
adaptorValueConversionClassName =
er.extensions.foundation.ERXPropertyListSerialization;
adaptorValueConversionMethodName = jsonStringFromPropertyList;
allowsNull = Y;
columnName = dictionary;
externalType = VARCHAR2;
factoryMethodArgumentType = EOFactoryMethodArgumentIsNSString;
name = dictionary;
valueClassName = Object;
valueFactoryClassName =
er.extensions.foundation.ERXPropertyListSerialization;
valueFactoryMethodName = dictionaryForJSONString;
valueType = S;
width = 4000;
},
Once the entity generated to a class, you have to change the _TheEntity.java
file and change the type of the attribute from Object to NSDictionary *1*.
Since there is a problem with mutable object as attribute (maybe there is
another way to fix it?), you have to consider the attribute as immutable and
use cover method to a mutable one.
So when you need to deal with an immutable version, do it with
mutableDictionary().
If you just need to ask contents, simply use dictionary();
Use the following code in TheEntity.java:
LeanMutableDictionary _mutableDictionary = null;
public LeanMutableDictionary mutableDictionary() {
if (_mutableDictionary == null) {
_mutableDictionary = new LeanMutableDictionary();
}
return _mutableDictionary;
}
/**
* Cover class to ease KVC. This « lean » version remove key when value
is null or Boolean.false.
*/
public class LeanMutableDictionary implements NSKeyValueCoding {
@Override
public Object valueForKey(final String key) {
final NSDictionary dict = userInfoDict();
if (dict != null) {
return dict.valueForKey(key);
}
return null;
}
@Override
@SuppressWarnings(unused)
public void takeValueForKey(final Object val, final String key)
{
NSDictionary dict = userInfoDict();
if (dict == null) {
dict = NSDictionary.EmptyDictionary;
}
dict = dict.mutableClone();
if (val == null || val.equals(Boolean.FALSE)) {
// remove that key from the dictionary
dict.remove(key);
} else {
dict.takeValueForKey(val, key);
}
setUserInfoDict(dict.immutableClone());
}
}
[1] This is because the type (valueClassName) will be used to find the right
method (with the type argument) and the method is defined in
ERXPropertyListSerialization with Object, not NSDictionary. So you have to
keep it Object.

Fix: So when you need to deal with an immutable version, do it with mutableDictionary().
