對於某些reaso SUgar ORM不會創建我的實體。我試圖禁用完好的運行，增加了數據庫版本，完全卸載應用程序，但似乎沒有工作。我正在使用糖ORM版本1.4。這裏是錯誤日誌，我得到Sugar ORM 1.4 E/SQLiteLog：（1）沒有這樣的表格：COURTS

這該是多麼想創建一個記錄
Courts newCourt = new Courts("Milimani Law Courts","Nairobi","supreme");
newCourt.save();
另一位用戶也提到了這一點https://stackoverflow.com/questions/38292116/sugarorm-error-或缺失的數據庫/ 39514488＃39514488。我反覆使用版本1，沒有任何副作用，更改版本實際上對你有幫助嗎？ – JakeSteam
@Jake是的，它幫助了我。 SugarORM無法創建兩列簡單的表格。在我從AVD模擬器中刪除了所有內容後，將db版本更改爲2，並且一切正常。 – TomTom
