Passing Multiple Params - Rails Controller

Question

Newb RoR developer here.

I have a model called size.rb that basically has a variety of size elements.

Now, in my subsequent view, I have multiple sets of radio_button_tags . Since each set is independent, I renamed the each ( shirtsize_ids , waistsize_ids , etc)

Now, the issue I'm having is how to pass all of these different size_id parameters to the controller. At the end of the day, they are all recorded as a size_id attribute in a joint-model called usersize, but since I had to differentiate them in the view (for radio button purposes), I'm stuck!

Thanks for the help

view

<% Size.select { |size| size.category == 'waist' }.sort.each do |size| %>
<%= radio_button_tag 'waistsize_ids[]', size.id, false, :id => "waistsizing-#{size.id}" %>
<% Size.select { |size| size.category == 'waist' }.sort.each do |size| %>
<%= radio_button_tag 'inseamsize_ids[]', size.id, false, :id => "inseamsizing-#{size.id}" %>

controller

def create
  @user_size = UserSize.new(params[:user_size])    
  params = {"waistsize" => {'id' => 'size.id'}}
  params.each do |size|

  UserSize.create(:size_id => size.id, :user_id => current_user.id)
  end
end

Answer 1

radio_button versus radio_button_tag might be a better choice:

<%= radio_button :waistsize, :id, size.id, :checked => false, :id => "waistsizing-#{size.id}" %>
<%= radio_button :inseamsize, :id, size.id, :checked => false, :id => "inseamsizing-#{size.id}" %>

# => params = { ..., "waistsize"=>{"id"=>"xyz"}, "inseamsize"=>{"id"=>"xyz"} }

Then, in the controller:

def create
  @user_size = UserSize.new(params[:user_size])    
  UserSize.create(:size_id => params[:waistsize][:id], :user_id => current_user.id)
  UserSize.create(:size_id => params[:inseamsize][:id], :user_id => current_user.id)
end

Answer 2

UserSize模型是否类似于'size_type'，或者为什么你有'waistsize'和'inseamsize'等等。
