问题描述
我希望能够看到类似数据库中的TwitchTV名称的字符串。这是我当前的代码
I want to be able to see the string like the TwitchTV name I have in my database. Here is my current code
get '/watch/:id' do |id|
erb :mystream
@result = Twitchtvst.all( :fields => [:Twitchtv ],
:conditions => { :user_id => "#{id}" }
)
puts @result
end
终端产生的结果;
#< Twitchtvst:0x007fb48b4d5a98 >
如何将其放入字符串中(数据库中的TwitchTV答案)
How do I get that into a string (TwitchTV answer in database)
Opppppsss!
Opppppsss!
这是真实的代码示例。抱歉!
Here is the real code sample. Sorry!
get '/livestream' do
erb :livestream
@users_streams = Twitchtvst.all
puts @users_streams
end
如果我在users_stream上添加.to_s,则不会工作
If I add .to_s at users_stream it does not work
推荐答案
通过添加 .to_csv
,不完全是一个字符串,但是它应该显示内容:
By adding .to_csv
, not exactly a string, but it should show the content:
get '/livestream' do
erb :livestream
@users_streams = Twitchtvst.all
@users_streams.each do |us|
p us.to_csv
end
end
