将解析的变量传递到不同的模型形式

Question

I have a products scaffold set up, and I just created a new foo controller and view. In my foo controller I parse a url, and get back an arry of objects. How can I pass each of these variables into the products form as defaults?

my controller:

     require 'net/http'
  require 'json'

def index
    if params[:commit] == "Add Product"
      @productId = params[:q]
      @resultsReceived = true
      if 
          url =  URI.parse("url" + params[:q].to_s)
          @response = JSON.parse(Net::HTTP.get_response(url).body)
      end
    else
      @resultsReceived = false
      @response = []
    end

     respond_to do |format|
        format.html
      end
end
end

My current index

<%= form_tag("/foo", :method => "get") do %>
  <%= label_tag(:q, "Enter Product Number") %>
  <%= text_field_tag(:q) %>
  <%= submit_tag("Add Product") %>
<% end %>

    <% if @resultsReceived == true %>
        Title:   <%= @response["product"]["title"] %>   </br>
        ID_Str:   <%= @response["product"]["id_str"] %> </br>
        Image Url:  <%= @response["product"]["image_url"] %>    </br>
        Base Item Price:  <%= @response["product"]["base_item_price"] %>    </br>
        Current Item Price:  <%= @response["product"]["price"] %>   </br>
        Seller Name:  <%= @response["product"]["mp_seller_name"] %> </br>
        Description:    <%= @response["product"]["descr"] %>    </br>
    <% end %>

I want the variable above to be passed to my already existing products from.

I think you have to move the access of the other data from your index action to either your your new action, or an action you create 'new_prefilled' possibly. It would helpful if the attributes matched (the stuff you get from the url has the same attribute names as your product model)

ie

def new_prefilled

  if url =  URI.parse("url" + params[:oid].to_s)
    @response = JSON.parse(Net::HTTP.get_response(url).body)
  end
  @product = Product.new(@response['product'])
  render 'new'
end

Then you'd have to add a route,

get '/products/new/:oid' => 'products#new_prefilled'

Then in your index action, you would do this:

if params[:commit] == "Add Product"
  redirect_to "/products/new/#{params[:q]}"
end

So you would render your new products view, but it would be pre-filled with that data you got from the other site.
