ruby on rails - Impossible to acces to value in database -

i'm rails newbie !

i know why in different case, 1 work, 1 doesn't.

### in controller ### def watch_randurl   # @dat = video.where(url_rand: params[:url_rand])   @dat = video.find(1) end 

with find(1), have database , in view work!

### in view ### <%= @dat.url_rand %> <br> 

but where have undefined method 'url_rand' <video::activerecord_relation:0x007fcbfeece1c8>

ps: sorry english :/ of course, need work where.

solve : video.where(url_rand: params[:url_rand]).first thank !

but have undefined method 'url_rand' video::activerecord_relation:0x007fcbfeece1c8

where returns activerecord_relation, in case, need modify @dat = video.where(url_rand: params[:url_rand]), @dat = video.where(url_rand: params[:url_rand]).first

or

you can iterate on @dat below, without changing value of @dat

<% @dat.each |dat| %>   <%= dat.url_rand %> <br> <% end %>
