Rails: Access parameters in view after form submission
ruby, ruby-on-rails, ruby-on-rails-3, ruby-on-rails-3.2
Solution
You're redirecting to a different action - this will reset all the parameters you passed to the create action.
Either pass `hash_name` as a parameter like the other answer suggests, or just fetch it straight from the `@site` object.
Problem
In my Rails 3.2 project, I have a form to create a new site in `new.html.erb` in `app/views/sites/` ``` <%= form_for(@site) do |site_form| %> ... <div class="field"> <%= site_form.label :hash_name %><br /> <%= site_form.text_field :hash_name %> </div> ... <div class="actions"> <%= site_form.submit %> </div> <% end %> ``` Then the `create` function in `sites_controller.rb` ``` def create @site = Site.new(params[:site]) respond_to do |format| if @site.save format.html { redirect_to @site } else format.html { render action: "new" } end end end ``` Then after the user submits, I want to show the `hash_name` that the user just submitted, in `show.html.erb` ``` You just put in <%= params[:hash_name] %>. ``` But accessing `params[:hash_name]` doesn't work. How can I access it?
