Ruby on Rails：需要将下拉的ID /值传递回控制器

Question

I'm new to RoR and I'm trying to pass the drop down id selected by the user back to the controller to load a page specific to a business. I have a simple DB listing ten businesses which loads fine but when I select an option I'm getting this error: No route matches [POST] "/businesses/1/2/3/4/5/6/7/8/9/10"

Can I get the action value to be dynamic for the form? What are some options?

Controller: businesses_controller.rb

  def home
    @business_dd = Business.find(:all)
  end

  def update
    @business = Business.find(params[:id])
    redirect_to :action => "show", :id => @business
  end

  def show
    @business_dd = Business.find(:all)
    @business = Business.find(params[:id])
  end

View: _header.html.erb

<%= form_for :business, :url => business_path(@business_dd) do |f| %>               
        <%= f.select(:id, options_for_select(
        @business_dd.map{ |f| [f.name, f.id]}), 
        :include_blank => 'Please select') %>
        <%= f.submit "Submit" %>
    <% end %>

HTML generated for the drop down:

<form accept-charset="UTF-8" action="/businesses/1/2/3/4/5/6/7/8/9/10" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="&#x2713;" /><input name="authenticity_token" type="hidden" value="FS7sYiq8NicsKfnUwzTTHpobtA180qOjcAOnuWNONPc=" /></div>                
<select id="business_id" name="business[id]"><option value="">Please select</option>
<option value="1">Business1</option>
<option value="2">Business2</option>
<option value="3">Business3</option>
<option value="4">Business4</option>
<option value="5">Business5</option>
<option value="6">Business6</option>
<option value="7">Business7</option>
<option value="8">Business8</option>
<option value="9">Business9</option>
<option value="10">Business10</option></select>
<input name="commit" type="submit" value="Submit" />
</form>

Routes:

      Prefix Verb   URI Pattern                    Controller#Action
  businesses GET    /businesses(.:format)          businesses#index

Answer 1

in routes.rb

resources :businesses, only: [:allowed, :actions, :here]

then it is better to include action new in controller

def new
  @business = Business.new
end

and use it with view new.html.erb (not home.html.erb ) to render form to submit:

<%= form_for @business do |f| %>  
  ...

Answer 2

I was able to simplify the drop down and get the path to work:

<%= form_tag(new_business_path, method: 'get') do |f| %> 
   <%= select_tag(:id, 
   options_for_select(Business.find(:all).map{ |f| [f.name, f.id]}), :prompt => "Select Venue") %> 
   <%= submit_tag "Submit" %> 
<% end %>
