我正在使用vision.enums.Feature.Type.DOCUMENT_TEXT_DETECTION来提取pdf文档中的一些密集文本。下面是我的代码: from google.cloud import vision
def extract_text(bucket, filename, mimetype):
print('Looking for text in PDF {}'.format(filename))
# BATCH_SIZE; How many pages should be grouped into each json output fi
我需要在Rails中创建和分页列表的帮助。我有三门课:
class User < ActiveRecord::Base
has_many :rankings, :dependent => :destroy
#...
# has id, name, email, etc.
end
class Ranking < ActiveRecord::Base
belongs_to :essay
belongs_to :user
#...
#has comment, score, essay_id, user_id
end
class Essay <
我已经尝试过获取视频时长的方法,通过这个GET
并传递此参数
https://www.googleapis.com/youtube/v3/videos?
id=QoQ_dHCi-08& // video id
list=RDUZWrltQLTzE& // playlist id (TODO from this i want full duration)
part=snippet,contentDetails&
key={MYAPIKEY}&
format=json&
fields=items(snippet(title),contentDetails
我试图将列表从一个视图传递到另一个控制器,但我得到的值是空值。代码编写如下:
模型类:
public class testModel
{
public int ID { get; set; }
public string Name { get; set; }
public List<myModel> ParameterList {get;set;}
}
用于将数据发布到控制器的jquery和ajax代码:
var myModel = {
"Name":"test",
