我正在對我自己版本的heroku rails移動iOS照片共享應用程序進行收尾。我已經在iOS上通過HTTP實現併成功發送了POST和GET請求。不幸的是,Heroku教程明確指出它已經勝利,不會去寫如何編寫DELETE請求。這是我到目前爲止有:使用Rails AFNetworking和DELETE請求
+ (void)deletePhoto:(NSString *)owner
image:(NSString *)recordId
block:(void (^)(Photo *, NSError *))block
{
NSMutableDictionary *mutableParameters = [NSMutableDictionary dictionary];
[mutableParameters setObject:recordId forKey:@"photo[id]"];
NSLog(@"Destroying %@", recordId);
[[CloudGlyphAPIClient sharedClient] deletePath:@"/photo" parameters:mutableParameters success:^(AFHTTPRequestOperation *operation, id JSON) {
if (block) {
NSLog(@"DELETE sussessful");
}
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
if (block) {
block(nil, error);
}
}];
}
+ (void)getPhotos:(NSString *)owner
block:(void (^)(NSSet *photos, NSError *error))block
{
NSMutableDictionary *mutableParameters = [NSMutableDictionary dictionary];
[mutableParameters setObject:owner forKey:@"photo[owner]"];
[[CloudGlyphAPIClient sharedClient] getPath:@"/photos" parameters:mutableParameters success:^(AFHTTPRequestOperation *operation, id JSON) {
NSMutableSet *mutablePhotos = [NSMutableSet set];
for (NSDictionary *attributes in [JSON valueForKeyPath:@"photos"]) {
Photo *photo = [[Photo alloc] initWithAttributes:attributes];
[mutablePhotos addObject:photo];
}
if (block) {
block([NSSet setWithSet:mutablePhotos], nil);
}
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
if (block) {
block(nil, error);
}
}];
}
我已經根據關GET請求的刪除請求,但在這種情況下,我們正在尋找一個特定的圖像用戶一定的所有者。我得到一個錯誤,路由文件不包含DELETE /照片的路徑...我添加了銷燬方法的rails應用程序和raked routes.rb文件。
我覺得這是一個軌道GOTCHA地方..感謝您的幫助^ _^
TL; DR試圖寫,刪除請求一個Rails應用程序與AFNetworking
它看起來像deletePath應該是嘗試刪除資源的網址 - 不知道如何形成?此外,Rails應用程序使用回形針,但我認爲在銷燬方法,我只需要說'@ photo'.image.destroy。照片是ActiveRecord,圖像是附件字段。 –
