link_to is not working with a variable url

I have a view that uses link_to to pass parameters to a controller. The url is a variable. Something is not working. I'd appreciate any clues. Thanks!

<% url1 = dialogs_path(@dialogId) %>
<%= url1 %>
<%= link_to "Go!", url1(:uid1 => @uid1, :uid2 => @uid2), :id => "my_link" %>

url1 displays correctly. However, executing link_to crashes.

Solution

  • You should use dialog_path(@dialogId) instead.

    You're trying to view a particular object, it's singular and what rails expects. Take a look here : http://guides.rubyonrails.org/routing.html#paths-and-urls

    The way you use url confuses me, try something like this :

    <%= link_to "Go!", dialog_path(@dialogId, :uid1 => @uid1, :uid2 => @uid2), :id => "my_link" %>
