DBFlow Version: 4.1.1 Issue Kind (Bug, Question, Feature): Bug

I add new column to table cause crash

Description: I added some tables in my app with DBFlow in previous app version. Now I want to add new column to one of tables in new version of app. When I update and run the app, the app crashes. But I remove previous version and install new version, any things are ok. logcat report:

FATAL EXCEPTION: main Process: com.consoleco.console, PID: 12896 android.database.sqlite.SQLiteException: table Message has no column named link (code 1): , while compiling: INSERT OR REPLACE INTO Message(messageId,date,sender,messageTitle,messageBody,link) VALUES (?,?,?,?,?,?) at android.database.sqlite.SQLiteConnection.nativePrepareStatement(Native Method) at android.database.sqlite.SQLiteConnection.acquirePreparedStatement(SQLiteConnection.java:893) at android.database.sqlite.SQLiteConnection.prepare(SQLiteConnection.java:504) at android.database.sqlite.SQLiteSession.prepare(SQLiteSession.java:588) at android.database.sqlite.SQLiteProgram.<init>(SQLiteProgram.java:58) at android.database.sqlite.SQLiteStatement.<init>(SQLiteStatement.java:31) at android.database.sqlite.SQLiteDatabase.compileStatement(SQLiteDatabase.java:1017) at com.raizlabs.android.dbflow.structure.database.AndroidDatabase.compileStatement(AndroidDatabase.java:56) at com.raizlabs.android.dbflow.structure.ModelAdapter.getInsertStatement(ModelAdapter.java:119) at com.raizlabs.android.dbflow.structure.ModelAdapter.getInsertStatement(ModelAdapter.java:58) at com.raizlabs.android.dbflow.sql.saveable.ModelSaver.save(ModelSaver.java:29) at com.raizlabs.android.dbflow.structure.ModelAdapter.save(ModelAdapter.java:185) at com.raizlabs.android.dbflow.structure.BaseModel.save(BaseModel.java:62) at com.consoleco.console.object.Message.<init>(Message.java:63) at com.consoleco.console.page.SupportPage$2$1.onResponse(SupportPage.java:123) at retrofit2.ExecutorCallAdapterFactory$ExecutorCallbackCall$1$1.run(ExecutorCallAdapterFactory.java:70)at android.os.Handler.handleCallback(Handler.java:808) at android.os.Handler.dispatchMessage(Handler.java:103) at android.os.Looper.loop(Looper.java:193)at android.app.ActivityThread.main(ActivityThread.java:5345) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:515) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:824) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:640) at dalvik.system.NativeStart.main(Native Method)

I tested these: I increased integer of version = MyDatabase.VERSION I increased app versionCode I disabled Instant Run

But the problem not solved.

Did you create a migration for the incremented database version? This would be the migration if your database version was bumped up to version 6 and your new column was called “new_column”.

@Migration(version = 6, database = BusySdkDatabase.class)
public class FiveToSix extends BaseMigration
{
    @Override
    public void migrate(DatabaseWrapper database)
    {
        database.execSQL("ALTER TABLE `Database_Model` ADD COLUMN `new_column` TEXT;");
    }
}

Below is my migration class @Migration(version = 7, database = XYZDatabase.class) public class Migration6 extends BaseMigration {

@Override
public void migrate(DatabaseWrapper database) {
    database.execSQL("ALTER TABLE `User` ADD COLUMN `username` TEXT;");
}

}

but it still table User has no column named username (code 1): , while compiling: INSERT INTO User(userId,name,phone,thumb,placeholder,username) VALUES (?,?,?,?,?,?) crash.
