Forms, nested resources and routing errors Rails 4 - ruby-on-rails-4

Question

Rails newbie here. I have created a basic website that tracks events during a shift. I have created the models and nested them. However, I do not understand the connections completely.
When I create the nested event from a form linked to a shift I get the following error:
No route matches [POST] "/shifts/events" on url http://localhost:3000/shifts//events
should be http://localhost:3000/shifts/3/events/1 I think
_form.html.erb
<%= form_for shift_events_path(#shift) do |f| %>
<% if #event.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#event.errors.count, "error") %> prohibited </h2>
<ul>
<% #event.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :time_s %><br>
<%= f.time_select :time_s %>
</div>
<div class="field">
<%= f.label :time_f %><br>
<%= f.time_select :time_f %>
</div>
<div class="field">
<%= f.label :odometre %><br>
<%= f.number_field :odometre %>
</div>
<div class="field">
<%= f.label :location %><br>
<%= f.text_field :location %>
</div>
<div class="field">
<%= f.label :activity %><br>
<%= f.text_field :activity %>
</div>
<div class="field">
<%= f.label :description %><br>
<%= f.text_area :description, rows: 4 %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>

I figure the form first line is wrong but I don't know what to change it to. Secondly, I think some the connections in the events controller are wrong. Any help would be appreciated.

Answer 1

Try this:
<%= form_for [#shift, #event] do |f| %>
Now you will post a particular event for a particular shift.
