java - In ActiveAndroid Is it possible to update a specific field in a table row without wiping out the rest of the data in the row -

activeandroid:

i need push updates specific table fields without wiping out existing data in row if dont happen save() data fields each time.

for example:

i have table named 'user' contains following fields:

extsrc | extid | email | firstname | lastname | role | photo | userid | verified

if save data fields except 'verified' , later need update verified field - possible?

currently when use code below, fields except userid (which have stored locally) , verified populated, other fields cleared. @ time have verified value need update dont have additional user data push / save() need update specific 'verified' field when userid matches userid in user table , leave other fields user are.

my code:

model:

    // define table name     @table(name = "user")      public class user extends model      {     // define table columns      @column(name = "extsrc")     public string extsrc;      @column(name = "extid")     public string extid;      @column(name = "email")     public string email;      @column(name = "firstname")     public string firstname;      @column(name = "lastname")     public string lastname;      @column(name = "role")     public string role;      @column(name = "photo")     public string photo;      @column(name = "userid", unique = true, onuniqueconflict = column.conflictaction.replace)     public string userid;      @column(name = "verified")     public string verified;     }   controller:       public class useradapter implements jsondeserializer {      @override     public user deserialize(jsonelement arg0, type arg1,         jsondeserializationcontext arg2) throws jsonparseexception {              user u = new user();              log.v("user", u.tostring());              jsonobject j = (jsonobject) arg0;              log.v("j", j.tostring());               if(j.has("extsrc"))             {                 u.extsrc = j.get("extsrc").getasstring();                 log.v("extsrc", u.extsrc);             }             else             {                 log.v("extsrc", "does not exist");             }               if(j.has("extid"))             {                 u.extid = j.get("extid").getasstring();                 log.v("extid", u.extid);             }             else             {                 log.v("extid", "does not exist");             }               if(j.has("email"))             {                 u.email = j.get("email").getasstring();                 log.v("email", u.email);             }             else             {                 log.v("email", "does not exist");             }               if(j.has("firstname"))             {                 u.firstname = j.get("firstname").getasstring();                 log.v("firstname", u.firstname);             }             else             {                 log.v("firstname", "does not exist");             }               if(j.has("lastname"))             {                 u.lastname = j.get("lastname").getasstring();                 log.v("lastname", u.lastname);             }             else             {                 log.v("lastname", "does not exist");             }               if(j.has("role"))             {                 u.role = j.get("role").getasstring();                 log.v("role", u.role);             }             else             {                 log.v("role", "does not exist");             }               if(j.has("photo"))             {                 u.photo = j.get("photo").getasstring();                 log.v("photo", u.photo);             }             else             {                 log.v("photo", "does not exist");             }               if(j.has("userid"))             {                 u.userid = j.get("userid").getasstring();                 log.v("userid", u.userid);             }             else             {                 log.v("userid", "does not exist");             }               if(j.has("verified"))             {                 u.userid = spontlyapplication.prefs_user_id;                 u.verified = j.get("verified").getasstring();                  log.v("verified", u.verified);             }             else             {                 u.verified = "true";                 log.v("verified", "does not exist");             }       u.save();       }    

thanks.

if want update existing user in database, need retrieve first database , update fields before calling save();

something like:

user user = new select().from(user.class).where("userid = ?", useridyouwanttoretrieve).executesingle();  if (user != null){    user.setverified(true); } else {    user = new user(){//populate new user here json } }  user.save(); 

this keep users values stored in database , update new values want.
