Hi,
I'm developing my first RoR application and working first time with
cookies on RoR.
I create a product object, save it and set the id into the cookie
def create
@image = Image.new(params[:image])
respond_to do |format|
if @image.save
@product = Product.new
@product.image_id = @image.id
@product.order_id = @order.id
@product.save
cookies[:product_id] = @product.id.to_s
flash[:notice] = 'Image was successfully created.'
format.html {redirect_to('/karte/waehlen')}
format.xml { render :xml => @image, :status => :created,
:location => @image }
else
format.html { render :action => "new" }
format.xml { render :xml => @image.errors, :status =>
:unprocessable_entity }
end
end
end
Then I redirect to the "karte" controller and "waehlen" action
The karte controller looks like this
class KarteController < ApplicationController
def waehlen
@product = Product.find(cookies[:product_id])
@image = Image.find(@product.image_id)
end
end
I try to get the product_id from the cookie.
The waehlen.html.erb looks like
<div id="formatCenterContainer">
<%= image_tag(@image.filename, :size => "190x153") %>
</div>
I get a NoMethodError
You have a nil object when you didn't expect it!
The error occurred while evaluating nil.filename
Extracted source (around line #12):
9:
10: </div>
11: <div id="formatCenterContainer">
12: <%= image_tag(@image.filename, :size => "190x153") %>
I checked the Cookie folder on my filesystem. There is no Cookie.
Do I have activate cookies? I already browsed for the problem, but I
find only information about read/write cookies and other options.
Cheers Adam
