breeze - How to add a property to an EntityType after it has been added to the Data Store? -


i have entity framework code first model column not mapped still want persist between server , client. model looks similar many more properties:

public class ownerinformation {     [key]     [databasegeneratedattribute(databasegeneratedoption.identity)]     public int id { get; set; }      [required]     [maxlength(16)]     public byte[] ssnencrypted { get; set; }      [notmapped]     [maxlength(9)]     [minlength(9)]     public string ssn { get; set; } }

when metadata retrieved breeze ssn not part of it, when data sent on wire ssn there. let breeze deal mapping through metadata, able still pass ssn between client , server , track it's state need encrypt before saved db.

i tried adding after metadata fetched this:

var ownertype = manager.metadatastore.getentitytype('ownerinformation'); var ssn = new breeze.dataproperty({   name: 'ssn',   datatype: breeze.datatype.string,   isnullable: false,   maxlength: 9 }); ownertype.addproperty(ssn);

but error: the 'ownerinformation:#models' entitytype has been added metadatastore , therefore no additional properties may added it.

maybe i'm overthinking , there easier way. i'm opened suggestions.

i took different approach , decided change metadata @ runtime on server. here's how did it. 

public class mycontextprovider : efcontextprovider<mycontext> {   protected override string buildjsonmetadata()   {     string metadata = base.buildjsonmetadata();     jobject json = jobject.parse(metadata);     var entityownerinfo = json["schema"]["entitytype"].children().where(j => (string)j["name"] == "ownerinformation").singleordefault();     var propertyarray = entityownerinfo["property"] newtonsoft.json.linq.jarray;      jtoken ssnpropertytype = jtoken.parse(@"{       ""name"": ""ssn"",       ""type"": ""edm.string"",       ""fixedlength"": ""true"",       ""maxlength"": ""9"",       ""minlength"": ""9"",       ""nullable"": ""false""}");     propertyarray.add(ssnpropertytype);      return json.tostring();   } }

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
