Trying to redirect to an external website

Rails
1

I’m looking for this to work

<%= redirect_to(post.link_url) %>

I tried this a few different ways. All I get is

" undefined method `redirect_to’ "

when I try that.

How do you go about doing this?

From the <% %>, I assume you’re trying to do this in the view, but
redirect_to in fact belongs in the controller.

My controller looks like this:

def goto
redirect_to(deal.item_title)
end

I want to be able to enter a url in a field so when you see the post
you can click on the link that will bring you to another site.

With the controller made what do I put in the view?

Well, unless you want to do this with client-side JavaScript, you’ll
need to have your application process the data in the form. That means
you need a controller action to which the form submits. In that action,
you will probably have something like
redirect_to(params[:destination_url]).

Think about how the request cycle works for a typical Web application,
and that will generally tell you where you should put your code.

Nothing needed in the controller, in your view, you do the following:

<%= link_to link.title, link.url, :popup => true %>
So link here is the object with attributes title and url. You can
hard-code these if you want, but in my application I store them in the
database so an example of hard-coded link would be:
<%= link_to “Google Search Home Page”, “http://www.google.com”, :popup
=> true %>

popup is optional and when specified opens the target in a separate
window. For more information, look up the documentation for “link_to”
in Rails docs.

This helps with a little with what I want to do but does not exactly
redirect. I did some research and I guess ruby rails does not have a
easy way to do this at all. This is where PHP would have the upper hand
in this area.

How so? PHP barely does anything to help out with links at all
(although maybe some frameworks do). Besides, I’ve already explained
how to use redirect_to. What is it that you want that Rails isn’t
giving you?

I just reread your description and realized something.

That shouldn’t work – where is deal defined?

I think what you’re looking for is link_to :action => ‘goto’, :deal =>
deal. You don’t need a view for the goto action, since it redirects
without rendering anything.
