Ransack not working (no error, just not functioning)

Question

Would love it if anyone can see what I'm doing wrong. Followed the docs: https://github.com/activerecord-hackery/ransack

My model defines that a Signup has_many Inventories

Controller code:

def index
  @q = Inventory.search(params[:q])
  @inventories = @q.result.includes(:signup)
end

View code:

<%= search_form_for @q, url: url_for(controller: 'inventories', action: 'index') do |f| %>
  <%= f.label :item_name_cont %>
  <%= f.search_field :item_name_cont %>
  <%= f.label :signup_email_cont %>
  <%= f.search_field :signup_email_cont %>
  <%= f.submit %>
<% end %>

<table>
  <thead>
    <tr>
      <th><%= sort_link(@q, :item_name, "Item", default_order: :desc) %></th>
      <th><%= sort_link(@q, 'signups.email', "Email") %></th>
      <th>Action</th>
      <th colspan="5"></th>
    </tr>
  </thead>
  <tbody>
    <% Inventory.all.each do |inventory| %>
      <tr>
        <td><%= inventory.item_name %></td>
        <td><%= inventory.signup.email %> %></td>
      </tr>
  </tbody>
</table>

Also, if it's helpful, if I remove the url: specification in the search form, I get an error: No route matches [GET] "/inventories/search"

Better Option

Please make sure that the view code that you posted is in views/inventories/index.html.erb file and change Inventory.all.each to @inventories.each. Then you would be able to access the search form at http://localhost:3000/inventories.

Or

From the error that you mentioned, it looks like you are doing this on /inventories/search page. If you want to stick to that URL, move your index method code into search method in your controller (as shown below) and add a route for search with GET in your routes file.

def search
  @q = Inventory.search(params[:q])
  @inventories = @q.result.includes(:signup)
end
