渲染缺少模板

Question

我的錯誤：

 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]}. Searched in:
2014-08-15T16:15:45.610918+00:00 app[web.1]:
2014-08-15T16:15:45.610928+00:00 app[web.1]:   * "/app/app/views"

控制器代碼：

  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

的CURL

curl -X POST -F“ photo = @ / path / path.jpg; type = image / jpg”“ http://magic-photo-app.herokuapp.com/api/magics/44/photosdescription=SomeDescription123&auth_token=DQWCqasiqVqYZxNp3W1y ”

工作並返回JSON。

當我發出此請求時，出現500和缺少模板錯誤

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];

為什么我的CURL成功，但是Obj-c中的HTTP POST失敗了？

途徑：

  namespace :api do
    resources :magics, only: [:index, :show, :create, :album] do
      resources :photos, only: [:index, :show, :create], controller: 'magic_photos'

編輯：

出現的實際錯誤是“圖像不能為空白”。

衛生署。 我的參數錯誤。 只是需要請某人查看一下。

Answer 1

檢查您的驗證，這是阻止您保存模型的原因，它進入了else語句。

錯誤消息應告訴您問題所在。

您可能還會遇到以下問題：

render status: 500

這是造成混亂和MissingTemplate錯誤的原因，您缺少了template參數

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

原來的問題是從Obj-C代碼發送的image是使用image查詢參數而不是photo 。
