[패스트캠퍼스 챌린지 24일차] Android book review 마무리

Book, History Review 모델을 만들고

bookDao, historyDao, reviewDao , appDatabase를 이용하여 데이터베이스를 처리해주었습니다.

@Parcelize data class Book( @SerializedName("itemId") val id: Long, @SerializedName("title") val title: String, @SerializedName("description") val description: String, @SerializedName("coverSmallUrl") val coverSmallUrl: String ):Parcelable

@Entity data class History ( @PrimaryKey val uid: Int?, @ColumnInfo(name = "keyword") val keyword: String? )

@Entity data class Review( @PrimaryKey val id: Int?, @ColumnInfo(name ="review") val review: String? )

@Database(entities = [History::class, Review::class], version = 2) abstract class AppDatabase:RoomDatabase() { abstract fun historyDao(): HistoryDao abstract fun reviewDao(): ReviewDao }

fun getAppDatabase(context: Context): AppDatabase{ val migration_1_2 = object : Migration(1,2){ override fun migrate(database: SupportSQLiteDatabase) { database.execSQL("CREATE TABLE `REVIEW` (`id` INTEGER, `review` TEXT,"+" PRIMARY KEY(`id`))") } } return Room.databaseBuilder( context, AppDatabase::class.java, "BookSearchDB" ) .addMigrations(migration_1_2) .build() }
