Hi all All my forms should look the same, so I think always putting the right div etc. tags around them is a violation of the DRY principle. Until now my forms look like that: <div class="text_field"> <label for="news_item_subject">Subject:</label> <%= text_field "news_item", "subject" %> </div> Now I want the default

Hi ActionView::Helpers::FormHelper methods (e.g. #text_field, #check_box...) take object_name as an argument. From this argument they infer a name that is supposed to contains the reference to the relevant object. I can''t see why the FormHelper methods were designed that way. Compared to simply passing them a reference, the current way seems too complicated and an invitation to problems

Anyone have a quick solution on how to format a number in a text_field tag? <% text_field "price", "amount" %> returns 100.0 and it would be nice if it showed 100.00 Of course, number_with_precision works nicely, but how do you make that work with text_field? I thought maybe overriding the getter in the model. However, this means I would have to bring the helper

All, Thanks for any help in advance. I have what I think is a very straightforward partial template and I can''t figure out why a text_field call within it doesn''t work. Here is my calling template: lists.rhtml <div id="target_lists"> <%= render(:partial => "target_lists", :collection => @target_lists) %> </div> In the partial

I''m playing around with Markaby and I decided to write a little blog app. I''m running into issues with forms however. If I use form_for the output of the form gets swallowed. For example: form_for :article, @article do |f| f.text_field :title f.check_box :published f.text_area :description f.text_field :pub_date f.text_area :content end gets rendered as an empty form
