问题
I have a model 'Article' and a model 'Ratings' nested within articles.
/articles/123/ratings
I want to change the routing of the f.submit in ratings/_form.html.erb now it is so, that after pressing submit, my application routs to
/ratings/111
but I want to route it to
/article/123
How can I change the routing in a form_for f.submit button. I have found here something like this:
<% form_for :thing, :url =>
url_for(:action => "update", :id => @thing) do |f| %>
But this do not work for my rails 3.2. Thanks for your help,
回答1:
:url - The URL the form is submitted to. It takes the same fields you pass to url_for or link_to. In particular you may pass here a named route directly as well. Defaults to the current action.
<% form_for :thing, :url => {:action => "update", :id => @thing} do |f| %>
you can also pass it the path_name by using the helper. so you can also do something like
:url => update_article_path(@article)

Try form_for (:thing, url:{:controller=>'thing', :action=>'update'}, html:{method:'put'}).
