How to define a Map in a YAML file?

[Marc-François Cochaux-Laberge]

Hi,

I'm writing a little application with Play! and I would like to know
how to define a Map in a YAML file.

This is an example of a syntax I tried: (found on this group):

myMap:
? key1
: value1
? key2
: value2
? key3
: value3

I have also tried this:

myMap: [key1; value1, key2: value2, key3: value 3]

These two examples compile, but return null if I try for example
myMap.get("key1");

Any suggestions?

Thanks.

you should have a look at SnakeYaml documentation, that's the library
used by play

http://code.google.com/p/snakeyaml/wiki/Documentation#YAML_syntax

you have several samples there

I've tried everything. Nothing works. All my Maps are null, but the
other properties are not null so my Yaml file works well.

Try it this way:

MyModel(mm):
myMap: {"key1":"value1","key2":"value2"}

I'm trying too to load a map from a yaml and nothing works. I tried
both of the suggestion above and it doesn't work. I get this message :
org.hibernate.PropertyAccessException: could not get a field value by
reflection getter of models.product.ProductAttributeLang.id

There's my definition :

Language(English):
name: English
isoCode: EN
isActive: true

product.ProductAttributeLang(ProductAttribute1LangEnSubscription1):
lang: English
name: Reccuring
description: Reccuring yearly

product.ProductAttribute(ProductAttribute1Subscription1):
available: true
productAttributeLangMap: {English :
ProductAttribute1LangEnSubscription1}

@Entity
public class ProductAttribute extends Model{

@OneToMany(mappedBy="productAttribute", cascade=CascadeType.ALL,
orphanRemoval=true)
@MapKey(name="lang")
public Map<Language, ProductAttributeLang> productAttributeLangMap;
public boolean available;
}

@Entity
public class ProductAttributeLang extends Model{
@ManyToOne
public ProductAttribute productAttribute;

@ManyToOne
public Language lang;

public String name;
public String description;
}

Is anybody know how to fix it ?

Thank you

I have the same problem....

The yaml document is rendered in a linked hash map and contains all entries in their own linked hash map, but when mapping on objects they are somehow ignored...

how it must be created in java:

Permission permission = new Permission()

permission.admin = true

permission.credential = new Credential()

permission.credential.connect = true

permission.credential.controllersAccess = new HashMap<String, Boolean>();
permission.credential.controllersAccess.put('Application.*', true)    //THIS WON'T BE DONE...

permission.credential.controllersAccess.put('OwnerPrivate.*', false) //NEITHER

how it should be presented in yaml:

Permission(perm):

admin: true

credential:

connect: true

controllersAccess:

? Application.*

: true

? OwnerPrivate.*

: false 

Thanks in advance (now I'm gonna try to catch the missing part or my mistakes, loading the play src in my IDE ^^)

Okay thanks,

I found the problem, and a way to resolve it. I posted it in the ticket...

Don't know how to do more unless do it myself... what I'll probably do :/
