playframework - Internationalization for user defined input -

i'm trying build localization user defined input. example: user define categories soccer in several languages.

the model entity have filed this:

    @manytomany          @mapkeycolumn(name = "locale", insertable = false, updatable = false)          public map<string, l18n> titles; 

i'd store localized strings this:

@entity public class l18n {      @id     @constraints.required     @formats.nonempty     public integer id;      public string key;      public string locale;      @column(columndefinition = "text")     public string text;  } 

we use yaml store testdata:

    category:          - !!models.category                 ...                 titles:                      - !!models.l18n                          key: soccer       l18n:           - !!models.l18n                 key: soccer                 locale: de-ch                 text: fdfdfsee           - !!models.l18n                 key: soccer                 locale: fr-ch                 text: dlfkjsdlfj 

with solution i'm getting error:

    [error] caused by: org.yaml.snakeyaml.error.yamlexception: no suitable constructor 1 arguments found interface java.util.map     [error]     @ org.yaml.snakeyaml.constructor.constructor$constructsequence.construct(constructor.java:574)     [error]     @ org.yaml.snakeyaml.constructor.baseconstructor.constructobject(baseconstructor.java:182)     [error]     @ org.yaml.snakeyaml.constructor.constructor$constructmapping.constructjavabean2ndstep(constructor.java:296)     [error]     ... 65 more 

i think problem you've defined titles map, don't use yaml mapping syntax define it. yaml collections

i think syntax titles should example here using langauges: yaml dictionary example

titles:      soccer: - !!models.l18n                 key: soccer                 locale: de-ch                 text: fdfdfsee     football: - !!models.l18n               ... 

if change format of .yml file l18n instances defined first , use references, yaml spec calls them alias nodes, make titles lot more streamlined:

l18n:       - &soccerde !!models.l18n             key: soccer             locale: de-ch             text: fdfdfsee       - &soccerfr !!models.l18n             key: soccer             locale: fr-ch             text: dlfkjsdlfj  category:      - !!models.category             ...             titles:                  soccerde: *soccerde                 soccerfr: *soccerfr
