form-for

I'm learning Spree 3.0 and I have a setup a test shop that sells shorts. Shorts has multiple option types: Size, Color, Length I wanted to change the way it displays the variant options on the frontend from a radio checkbox to a drop down box. Currently, Spree displays the option types as radio buttons: I want to change this to use drop down menus for each option type, like this: I've tried the following: <%= select_tag "variant_id", options_for_select(@product.variants_and_option_values(current_currency).collect{ |v| ["#{variant_options(v)} #{variant_price(v)}", v.id] })%> But it simply

Is there any documentation, or advice? Sinetris You can use Active Model Take a look here . Look at the source code at Github . Using ActiveAttr is the more modern way of doing this.

Ordinarily, using form_for(@foo) means that on the back end of the form's action, you'll have the form data in params[:foo] , but in my case I'd like to have a custom namespace applied to these params, i.e. params[:bar] , not params[:foo] . I'm not talking about making the namespace longer by supplying the :namespace argument to the form_for method. To the contrary, my current name is overlong, and I want to shorten it. More importantly, I'm actually swapping a new model in place of an existing one, so the controller is filled with calls to params[:quoter] , whereas our new model supplies

I can't figure out how to upgrade this code from Rails 2 to Rails 3: <% remote_form_for(item, :update => 'div_id') do |f| %> ... I tried this: <%= form_for :item, :remote => true, :url => { :controller => "items", :action => "create" }, :update => 'div_id' do |f| %> ... It creates the new item but it fails in updating the content within <div id="div_id"></div> tags. It seems Rails 3 no longer supports the " :update " option for a remote form_for . Any suggestion? You could use RJS, but that's being deprecated too (and for good reason). The simplified, best-practices way to handle this in Rails

I have some data associated with a model that is in a hash. The hash is generated in the controller: @hash . What is the proper way to create a form for this data? I came up with the following code for the view: <% @hash.keys.each do |key| %> <div class="field"> <%= f.label key %><br /> <%= text_field_tag "hash_" + key, @hash[key] %> </div> <% end %> This generates the form, but it creates each hash item as a separate variable in the form. This doesn't seem to be the proper way to submit the data back. I would like to get the data back as a hash, and access it with params[:hash] . What is the

I have this form_for: <%= form_for [post, Comment.new,], :remote => true do |f| %> <%= f.text_area :content, :cols =>10, :rows => 1%> <% end %> <%= f.submit :class => "input_comment" %> That generate the next code html: <form method="post" id="new_comment" data-remote="true" class="new_comment" action="/post/4efcda9e1d41c82486000077/comments" accept-charset="UTF-8"><div style="margin:0;padding:0;display:inline"><input type="hidden" value="✓" name="utf8"> <input type="hidden" value="ctVfDF/O4FIR91I7bC5MVezQmutOCkX3dcXe73uNPZY=" name="authenticity_token"> <textarea rows="1" name="comment[content

Is <%= form_for(:product, :url => {:action => 'update', :id => @product.id})) do |f| %> ... <% end %> and <%= form_for(@product, :url => {:action => 'update', :id => @product.id})) do |f| %> ... <% end %> exactly the same ? The @product in the form_for helper ships with more features. The :product only affects the input field's id and name. For example you have a text filed in the form: <%= form_for :product, :url => {...}　do |f| %> <%= f.text_field :price %> <% end %> The generated html would look like: <input type="text" id="product_price" name="product[price]" /> The id and name value is

I am learning RoR and i am trying to find how to set a fields_for in another one with has_one models like this: class Child < ActiveRecord::Base belongs_to :father accepts_nested_attributes_for :father end class Father < ActiveRecord::Base has_one :child belongs_to :grandfather accepts_nested_attributes_for :grandfather end class Grandfather < ActiveRecord::Base has_one :father end I used Nested Model Form Part 1 on Railscasts to get these: In children_controller.rb: def new @child = Child.new father=@child.build_father father.build_grandfather end def child_params params.require(:child)
