Rails 3.1.3 I believe this is a very very fundamental question, but since I am new to Rails, it''s more productive to ask someone to point out what I need to do. Say, I have a search method that generates a list of youtube videos. I have completed this part. And also, I have set up a database, Video, whose fields are video_title and URL. I need to place a button to each of these video outcomes. My question is : when clicking the button, how can I automatically send the URL of the corresponding video and simultaneously redirect to NEW page where users can create a new video entry??? In other words, in the creating new page, the URL (and hopefully the video_title) is to be already filled out. I am thinking that I need to set "routes.rb" so that redirecting can take some values together. But routing is very confusing to me so far. Could anyone help me out? soichi -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

When you say "send the URL" you don''t mean that the user should be sent to that page (whether in the same tab or window, or a new one), but simply that that should be the pre-filled value on the "New Video" page. Right? There may be a more "Railsy" way to do this, but what comes to my mind is: Have the links link to #new, but add a parameter called something like video_url. You could make it a URL parameter, so that rather than going to myvideostore.com/videos/new, you''d go to myvideostore.com/videos/new?video_url=http://youtube.com?watch=abc123 or whatever. (Actually the video_url should be url-encoded, but I think Rails will handle that for you.) To do that, I think you can pass a hash of params to link_to, or IWCTW you can tack it on manually. Or you can make them form params, so they don''t show up and look ugly on the URL after the user clicks. Make a tiny form for each one. Have the URL as a hidden field. Have the link submit the form, to the videos_controller#new. Either way, in the controller, after you call Video.new, set the object''s url to params[:video_url]. Then when you display it, the value should show up just fine. Let us know how that works for you. -Dave -- Dave Aronson: Available Cleared Ruby on Rails Freelancer (NoVa/DC/Remote) -- see www.DaveAronson.com, and blogs at www.Codosaur.us, www.Dare2XL.com, www.RecruitingRants.com -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thanks for your explanation. It is exactly what I wanted.
in search.html.erb, I added
<%= link_to(''RegisterThisMovie'', {:controller =>
''video'', :action =>
''new'', :url => y }) %>
''y'' contains the url of the movie after executing the search.
in video_controller.rb, I added
def new
@video = Video.new
@video.url = params[:url] #<---HERE
respond_to do |format|
format.html # new.html.erb
format.json { render json: @video }
end
end
then it worked fine!
Thanks for your help.

Now let''s take it to the next level. I think you can make it a little more "canonical". Instead of:> <%= link_to(''RegisterThisMovie'', {:controller => ''video'', :action => > ''new'', :url => y }) %> > > ''y'' contains the url of the movie after executing the search.try: <%= link_to( ''Register This Movie'', new_video_path, :url => y ) %> Also you can try getting used to the newer hash syntax, and do: <%= link_to( ''Register This Movie'', new_video_path, url: y ) %> I''m not 100% sure off the top of my head that these will work, but it should be at least close. :*) The built-in url helpers like new_whatever_path, edit_whatever_path(some_object), etc. will save you lots of typing and thus errors. -Dave -- Dave Aronson: Available Cleared Ruby on Rails Freelancer (NoVa/DC/Remote) -- see www.DaveAronson.com, and blogs at www.Codosaur.us, www.Dare2XL.com, www.RecruitingRants.com -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
