我在测试应用中使用Flickraw
关注example,
我可以通过Keying文件路径上传文件,但我想使用form_tag helper
这是我的观点
= form_tag :upload_photo_to_Flickr , :multipart => true do
= hidden_field_tag :token, @upload_info[:token]
= label_tag "PHOTO"
= file_field_tag :photo
= submit_tag "Upload Photo"
控制器
def upload_photo_to_Flickr
file_path = params[:photo]
flickr.upload_photo file_path , :title => "please" , :description=>"successfully"
end
显示错误消息 ArgumentError(错误的参数数量(1表示0))
我还尝试使用read,
的其他方法 def upload_photo_to_Flickr
file_path = params[:photo].read
flickr.upload_photo file_path , :title => "please" , :description=>"successfully"
end
它显示错误消息 ArgumentError(字符串包含空字节)
参数是
{"photo"=>#<ActionDispatch::Http::UploadedFile:0x10ba37648
@original_filename="test.jpg",
@tempfile=#<File:/var/folders/wy/5yx_py3s02g8l0kw0frrpg_m0000gn/T/RackMultipart20111110-
1832-18ufrmm-0>,
@headers="Content-Disposition: form-data; name=\"photo\";
filename=\"test.jpg\"\r\nContent-Type: image/jpeg\r\n",
@content_type="image/jpeg">,
"commit"=>"Upload Photo \350\201\236",
"token"=>"XXXX",
"authenticity_token"=>"o9PhVeE6u1MGfol/PvGQkLE8RCL5tJat+1AQlygGOKc=",
"utf8"=>"\342\234\223"
}
如何获取文件路径?
因为它可以像这样工作
def upload_photo_to_Flickr
file_path = "/Desktop/test.jpg"
flickr.upload_photo file_path , :title => "please" , :description=>"successfully"
end
或者我必须尝试其他方法来获取文件路径而不是form_tag?
答案 0 :(得分:2)
我找到了解决方案!
在控制器中,使用
flickr.upload_photo(PARAMS [:相片] .tempfile.path)
