Submit a form to a model from my homepage

I have a links model which has all the generic scaffold created for it, however, rather than go to the link#new page, I'd like to submit a form from my homepage that populates a new record.

I only have one text field, but im not sure how to construct the form. I read somewhere you have to specify the controller in the form field but this doesn't appear to be working.

<%= form_for(:link, @link) do |f| %>
  <% if @link.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@link.errors.count, "error") %> prohibited this link from being saved:</h2>

      <ul>
      <% @link.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  <div class="field">
    <%= f.label :url %><br />
    <%= f.text_field :url %>
  </div>

  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

You don't need to specify anything if you are using default routes.

If the @link is an object that doesn't exist in database, Rails will automatically think this is a form for #new. So the form action will be /links, and method is post, which is the default resource to #create

In your case, you don't need to do anything, just revise the form code to:

<%= form_for(@link) do |f| %>
....

Besides, you need to prepare @link object in home controller, something like

@link = Link.new

All you have to do is add a url parameter to the form_for helper

<%= form_for :link, url: your_home_path do |f| %>
