No Ransack Search object was provided to search_form_for

Question

I'm using the ransack gem, and it can't seem to find the search object, even though it's in my controller.

This is the index method

  def index
      if params[:q].present?
       @search = Patient.search(params[:q])
       @patients = @search.result
      else
       @patients = Patient.where(:user_id => params[:user_id])
      end
  end

This is the view form

<%= search_form_for @search do |f| %>
                <div class="field">
                    <%= f.label :name_cont, "Name" %>
                    <%= f.text_field :name_cont %>
                </div>
                  <div><%= f.submit %></div>
            <% end %>

Answer 1

You are conditionally setting search based on params[:q] which will never get generated because it relies on the form in your view.

I would revise your code in your controller like this

def index 
  @search = Patient.search(params[:q])
  @patients = @search.result
  if params[:q].blank?
    @patients = Patient.where(:user_id => params[:user_id])
  end
end

This way, you get your search prioritized if it's available, otherwise you scope it down to how you want it.
