YTXRestfulModel

YTXRestfulModel makes it easy to fetch(GET), save(PUT/POST) or destroy(DELEGATE) data by database, remote or local storage.(YTXRestfulModel提供一种简单的方式从数据库，远程或本地存储去拉取，储存，销毁数据)

Dependency(依赖)

FMDB ~>2.6(FMDBSync)
AFNetworking ~>2.6.3 (AFNetworkingRemoteSync)
Mantle ~>1.57.
Optional ReactiveCocoaFRP。

Support IPv6

Integration

You shouldn't just use: pod "YTXRestfulModel". Since CocoaPods 0.36+ you should do something like:

pod 'YTXRestfulModel', :subspecs => ["RACSupport", "YTXRequestRemoteSync", "FMDBSync", "UserDefaultStorageSync"]

Testing

git clone https://github.com/baidao/YTXRestfulModel.git
npm install -g json-server
cd Example
pod install
cd Tests
json-server db.json
open YTXRestfulModel.xcworkspace

Chose Target: YTXRestfulModel-Example Command+U to run Test

A Model Example(定义Model示例)

@interface YTXTestModel : YTXRestfulModel

Fetch

- (nullable instancetype) fetchStorageSync:(nullable NSDictionary *) param;

- (void) fetchRemote:(nullable NSDictionary *)param success:(nonnull YTXRestfulModelRemoteSuccessBlock)success failed:(nonnull YTXRestfulModelRemoteFailedBlock)failed;

- (nonnull instancetype) saveDBSync:(nullable NSDictionary *)param error:(NSError * _Nullable * _Nullable) error;

        return [NSDate dateWithTimeIntervalSince1970: timestamp.longLongValue / 1000];
    } reverseBlock:^(NSDate *date) {
        return @((SInt64)(date.timeIntervalSince1970 * 1000));
    }];
}

+ (MTLValueTransformer *)passwordJSONTransformer {
    return [MTLValueTransformer reversibleTransformerWithForwardBlock:^(NSString *value) {
        return [self encryption:value];
    } reverseBlock:^(NSString *value) {

[[collection rac_fetchRemote:@{@"_start": @"1", @"_limit": @"2"}] subscribeNext:^(YTXTestAFNetworkingRemoteCollection *x) {
    
} error:^(NSError *error) {

}];

Example:

  /**

  "userId": 1,
  "id": 1,
  "title": "sunt aut facere repellat provident occaecati excepturi optio reprehenderit",
  "body": "quia et suscipit\nsuscipit recusandae consequuntur expedita et cum\nreprehenderit molestiae ut ut quas totam\nnostrum rerum est autem sunt rem eveniet architecto"
  }
  */
  /**
  keyId = @1，按照JSONKeyPathsByPropertyKey方法中的映射转成retDictionary @{@"id":@1}；
  由于param为空，所以保留参数{@"id":@"1"}不做修改，直接执行同步操作，同步目标源中 id = 1 的数据；
  */
  YTXTestModel * currentTestModel = [[YTXTestModel alloc] init];
  currentTestModel.keyId = @1;
  [[currentTestModel rac_fetchRemote:nil] subscribeNext:^(YTXTestModel *responseModel) {

  } error:^(NSError *error) {

  }];

  /**
  Model的属性会按照映射转成retDictionary @{@"title":@"ytx test", @"body":@"test content", @"userId":@1}
  param按照映射转成mapParam，@{@"id":@2}；（param = @{@"id":@2} 时也会转成 @{@"id":@2}）。
  mapParam的value会替换retDictionary 的value,所以执行同步的参数是@{@"title":@"ytx_test", @"body":@"test_content", @"userId":@1, @"id":@1}
  由于retDictionary 中没有主键，所以不符合rest原则，最后发送的请求是: *******?title=ytx_test&body=test_content&userId=1&id=1
  */

  YTXTestModel * testModel = [[YTXTestModel alloc] init];
  testModel.title = @"ytx test";

RACSupport

#import <YTXRestfulModel/YTXRestfulModelRACSupport.h>

@interface YTXXXXModel : YTXRestfulModel

- (nonnull RACSignal *) rac_fetchFromRemoteAndStorage;

@end

@implementation YTXXXXXModel

- (nonnull RACSignal *) rac_fetchFromRemoteAndStorage
{
    RACSubject * subject = [RACSubject subject];
    [self fetchRemote:param success:^(id  _Nullable response) {
        [subject sendNext:response];
        [subject sendCompleted];
    } failed:^(NSError * _Nullable error) {
        [subject sendError:error];
        
    }];
    return subject;
}

@end

Use new sync

id<YTXRestfulModelStorageProtocol> storageSync;
id<YTXRestfulModelRemoteProtocol> remoteSync;
id<YTXRestfulModelDBProtocol> dbSync;

- (instancetype)init
{
    if(self = [super init])
    {
        self.storageSync = [YTXRestfulModelXXXFileStorageSync new];
    }
    return self;
}

YTXTestModel * model = [YTXTestModel new];
model.storageSync = [YTXRestfulModelXXXFileStorageSync new];

If necessary, You can also using sync like this(如果有必要你可以直接使用sync想这样)

#import <YTXRestfulModel/YTXRestfulModelUserDefaultStorageSync.h>

YTXRestfulModelUserDefaultStorageSync * sync = [[YTXRestfulModelUserDefaultStorageSync alloc] initWithUserDefaultSuiteName:suitName1]

DB mapping

Column Struct

YTXRestfulModelDBSerializingModel * dbsm = [YTXRestfulModelDBSerializingModel new];
dbsm.objectClass = propertyClassName;
dbsm.columnName = columnName;
dbsm.modelName = modelProperyName;
dbsm.isPrimaryKey = isPrimaryKey;
dbsm.autoincrement = isPrimaryKeyAutoincrement;
dbsm.unique = NO;

@interface YTXRestfulModelDBSerializingModel : NSObject

/** 可以是CType @"d"这种*/
@property (nonatomic, nonnull, copy) NSString * objectClass;

/** 表名 */
@property (nonatomic, nonnull, copy) NSString *  columnName;

/** Model原始的属性名字 */
@property (nonatomic, nonnull, copy) NSString *  modelName;

/** 是否 主键*/
@property (nonatomic, assign) BOOL isPrimaryKey;

/** 是否自增*/
@property (nonatomic, assign) BOOL autoincrement;

/** 是否唯一*/
@property (nonatomic, assign) BOOL unique;

/** 默认值*/
@property (nonatomic, nonnull, copy) NSString * defaultValue;

/** 外键类名 可以使用fetchForeignWithName */
@property (nonatomic, nonnull, copy) NSString * foreignClassName;

@end

Modify DB mapping in child Model

+ (nullable NSMutableDictionary<NSString *, YTXRestfulModelDBSerializingModel *> *) tableKeyPathsByPropertyKey
{
    NSMutableDictionary<NSString *, YTXRestfulModelDBSerializingModel *> * tmpDictionary = [super tableKeyPathsByPropertyKey];

    YTXRestfulModelDBSerializingModel * genderStruct = tmpDictionary[@"gender"];
    genderStruct.defaultValue = [@(GenderFemale) sqliteValue];
    tmpDictionary[@"gender"] = genderStruct;

    YTXRestfulModelDBSerializingModel * scoreStruct = tmpDictionary[@"score"];
    scoreStruct.unique = YES;
    tmpDictionary[@"score"] = scoreStruct;
    return tmpDictionary;
}

Open auto creating table, if you use DB function.(开启自动创建数据库表。需要使用DB时才这样做)

+ (BOOL) autoCreateTable
{
    return YES;
}

Close auto incremen (关闭主键默认自增)

+ (BOOL) isPrimaryKeyAutoincrement
{
    return NO;
}

DB Alter(自动扩展字段到表中)

+ (BOOL) autoAlterTable
{
    return YES;//Default
}

+ (nullable NSNumber *) currentMigrationVersion
{
    return @0;
}

currentMigrationVersion	Property	DB Column
0	Name,KeyId	name,keyid
1	Name,KeyId,title	name,keyid,title
2	Name,KeyId,title,age	name,keyId,title,age
3	Name,KeyId,title	name,keyId,title,age

DB Migration(数据库迁移)

// DB Migration（数据迁移）
+ (nullable NSNumber *) currentMigrationVersion
{
    return @0;
}

+ (BOOL) autoAlterTable
{
    return NO;//Not Default
}

currentMigrationVersion	Property	DB Column
0	KeyId,age	keyid,age
1	KeyId,age,title	keyId,age,title
2	KeyId,age,name	keyId,age,title,title=>name

sqlite does not support function rename an drop(sqlite并没有提供rename和drop column的方法)

Migration Example

//数据库迁移操作是从当前版本到最新版本依次进行的，所以本方法中要存储所有版本的迁移操作。
+ (void) migrationsMethodWithSync:(nonnull id<YTXRestfulModelDBProtocol>)sync;
{
  // 创建 数据库迁移的操作
    YTXRestfulModelDBMigrationEntity *migration = [YTXRestfulModelDBMigrationEntity new];
    // 设置 进行本次操作时的版本号
    migration.version = @1;
    // 设置 迁移操作（增、删、改）
    migration.block = ^(_Nonnull id db, NSError * _Nullable * _Nullable error) {
        YTXRestfulModelDBSerializingModel *runtimePStruct = [YTXRestfulModelDBSerializingModel new];
        runtimePStruct.objectClass = @"NSString";
        runtimePStruct.columnName = @"runtimeP";
        runtimePStruct.modelName = @"runtimeP";
        runtimePStruct.isPrimaryKey = NO;
        runtimePStruct.autoincrement = NO;
        runtimePStruct.unique = NO;
        // 创建新的列
        [sync createColumnWithDB:db structSync:runtimePStruct error:error];
    };
    // 存储 迁移操作
    [sync migrate:migration];
}

- (BOOL) createColumnWithDB:(nonnull id)db structSync:(nonnull YTXRestfulModelDBSerializingModel *)sstruct error:(NSError * _Nullable * _Nullable)error;

@optional

- (BOOL) renameColumnWithDB:(nonnull id)db originName:(nonnull NSString *)originName newName:(nonnull NSString *)newName error:(NSError * _Nullable * _Nullable)error;

- (BOOL) dropColumnWithDB:(nonnull id)db structSync:(nonnull YTXRestfulModelDBSerializingModel *)sstruct error:(NSError * _Nullable * _Nullable)error;

- (BOOL) changeCollumnDB:(nonnull id)db oldStructSync:(nonnull YTXRestfulModelDBSerializingModel *) oldStruct toNewStruct:(nonnull YTXRestfulModelDBSerializingModel *) newStruct error:(NSError * _Nullable * _Nullable)error;

Migration Delegate

+ (void)dbWillMigrateWithSync:(nonnull id<YTXRestfulModelDBProtocol>)sync
{
}

+ (void)dbDidMigrateWithSync:(nonnull id<YTXRestfulModelDBProtocol>)sync
{
}

Remote Hook

所有请求都会附带这些参数，hook的优先级最低，总是会被其他同名参数覆盖

NSDictionary *(^hook)() = ^NSDictionary *() {
    return @{
             @"deviceToken": objectOrEmptyStr([NotificationManager sharedManager].deviceToken),
             @"deviceId": objectOrEmptyStr([AppInfo deviceUUID]),
             @"marketId": objectOrEmptyStr([AppInfo marketId]),
             @"appVersion": objectOrEmptyStr([AppInfo appVersion])
    };
};

AFNetworkingRemoteSync.HookExtraParamBlock = hook;

Remote Hook Request

在发送请求的时候统一修改Header或者其他行为

AFNetworkingRemoteSync.hookRequestBlock = ^(AFNetworkingRemoteSync * sync, NSString * method, NSURL ** url, NSMutableDictionary ** paramters) {
    retParamters = *paramters;
    retParamters[@"title"] = @"XXXX";
    *paramters = retParamters;

    AFHTTPSessionManager * sessionManager = sync.requestSessionManager;
    [sessionManager.requestSerializer setValue:@"test" forHTTPHeaderField:@"x-auth-token"];
};
