Objective c 渲染时缺少模板

我的错误：

 ActionView::MissingTemplate (Missing template api/magic_photos/create, api/base/create, application/create with {:locale=>[:en], :formats=>[:html, :text, :js, :css, :ics, :csv, :png, :jpeg, :gif, :bmp, :tiff, :mpeg, :xml, :rss, :atom, :yaml, :multipart_form, :url_encoded_form, :json, :pdf, :zip], :handlers=>[:erb, :builder, :coffee, :rabl]}.

控制器代码：

  if photo.save
    magic_photo = photo.magic_photos.build( magic: magic )
    magic_photo.save
    render json: photo.json_hash(magic, current_user)
  else
    render status: 500
  end

一卷

curl-X POST-F“photo=@/path/path.jpg；type=image/jpg”“”

工作并返回JSON

当我提出这个请求时，我得到一个500和缺少的模板错误

description = [description stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

NSString *path = [NSString stringWithFormat:@"api/magics/%@/photos?description=%@&auth_token=%@", magic.identifier, description, [NSUserDefaults authToken]];

NSString *fullPath = [NSString stringWithFormat:@"%@%@", [CURequestHelpers baseURL], path];

NSData *imageData = UIImageJPEGRepresentation(image, 0.25f);
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:[CURequestHelpers baseURL]];

NSURLRequest *request = [httpClient multipartFormRequestWithMethod:@"POST" path:path parameters:@{} constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
    NSString *fileName = @"image.jpg";
    [formData appendPartWithFileData:imageData name:@"image" fileName:fileName mimeType:@"image/jpg"];
}];

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];


[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
    [self.delegate pictureUploadProxyUploadDidSucceed:self];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"UPLOAD ERROR RESPONSE: %@", operation.responseString);
    NSLog(@"UPLOAD ERROR: %@", error);
    [self.delegate pictureUploadProxyUploadDidFail:self];
}];

NSOperationQueue *q = [[NSOperationQueue alloc] init]; [q addOperation:operation];

编辑：

显示的实际错误是“图像不能为空”

Doh。我把参数搞错了。只需要请某人检查一下。

检查您的验证，有什么东西阻止保存您的模型，并将其放入您的

其他

语句中

错误消息应该会告诉您问题所在

您可能还存在以下问题：

render status: 500

这是导致混淆和

丢失模板

错误的原因，您缺少模板参数

render :template => "public/500.html", :status => 500

问题是，从Obj-C代码发送的图像是使用

image

查询参数发送的，而不是

photo

curl中有API，抱歉，我忘了。他在打字！那你的MagicPhoto模型呢，有没有验证呢？我上传的是“image”，因为那是模型的名字，但是使用的参数是“photo”。如果你想改变你的答案，我会接受并奖励赏金。自从您提出验证：）完成。还添加了一些关于丢失模板问题的备注。

render :template => "public/500.html", :status => 500
