Rails - Updating records using Best in Place - ruby-on-rails

Question

I'm building a marketplace app where I'm trying to use the Best in Place gem to allow sellers to add a tracking number for each of their orders.
I get a NoMethodError which I'm not able to resolve.
NoMethodError in Orders#sales
undefined method `tracking' for nil:NilClass
The error points to the best in place line below in the view page. This view page is based on the method Sales (in the controller below) where I filter for orders for that particular seller.
Here is my routes.rb with order routing. Since orders need not be edited or destroyed, I didn't create an edit or delete route.
resources :listings do
resources :orders, only: [:new, :create, :update]
collection { post :import }
end
Here is a snippet from my orders controller
class OrdersController < ApplicationController
before_action :set_order, only: [:show, :edit, :update, :destroy]
before_action :authenticate_user!
before_action :check_user, only: [:edit, :update]
def sales
#orders = Order.all.where(seller: current_user).order("created_at DESC")
end
def update
#order.update_attributes(params[:order])
end
def check_user
if current_user.id != #seller && current_user.name != "admin admin"
redirect_to root_url, alert: "Sorry, you are not the seller of this listing"
end
end
Here is my view page:
<table class="table table-striped table-bordered">
<tr>
<th class="col-md-2">Image</th>
<th class="col-md-2">Item</th>
<th class="col-md-1">Price</th>
<th class="col-md-2">Customer</th>
<th class="col-md-2">Date Sold</th>
<th class="col-md-2">Shipment Tracking #</th>
<th class="col-md-1">Carrier (UPS, USPS, etc.)</th>
</tr>
<% #orders.each do |order| %>
<tr>
<td><%= image_tag order.listing.image.url(:thumb) %></td>
<td><%= order.listing.name %></td>
<td><%= number_to_currency(order.listing.price) %></td>
<td><%= order.buyer.name %></td>
<td><%= order.created_at.strftime("%B %-d, %Y") %></td>
<td><%= best_in_place #order, :tracking, :type => :input %> </td>
<td><%= best_in_place #order, :carrier, :type => :input %></td>
</tr>
<% end %>
</table>
Been stuck on this for a while. Appreciate any help on this.

Answer 1

I think the problem is that you are calling #order inside your .each method.
Try:
<%= best in place order, :tracking, :type => :input %>
You will need to change the next line in your view as well.

Answer 2

I figured it out. The problem was that since I was using best_in_place in a non-Activerecord environment (as part of a table with a list of orders), I needed to pass the order id explicitly. I found this in the best_in_place documentation https://github.com/bernat/best_in_place#non-active-record-environments
I created a custom route for the update action
put 'orderupdate' => "orders#update"
Then in my do loop in the view, I used the custom path for the route above and passed the order id to that route.
<% #orders.each do |order| %>
<tr>
<td><%= order.id %></td>
<td><%= image_tag order.listing.image.url(:thumb) %></td>
<td><%= order.listing.name %></td>
<td><%= number_to_currency(order.listing.price) %></td>
<td><%= order.buyer.name %></td>
<td><%= order.created_at.strftime("%B %-d, %Y") %></td>
<td><%= best_in_place order, :tracking, :type => :input, :url => orderupdate_path(id: order.id) %> </td>
<td><%= best_in_place order, :carrier, :type => :input, :url => orderupdate_path(id: order.id) %> </td>
</tr>
<% end %>
Here is the update method in my controller:
def update
#order = Order.find(params[:id])
respond_to do |format|
if #order.update(order_params)
format.html { redirect_to sales_url, notice: 'Order updated.' }
format.json { head :no_content }
else
format.html { render action: 'edit' }
format.json { render json: #order.errors, status: :unprocessable_entity }
end
end
end
Hope this helps someone!
