In a standard scaffold generator, the list.rhtml looks something like this ... <% for column in Book.content_columns %> <th><%= column.human_name %></th> <% end %> How can I modify this code so for each table column add my own name not the "human_name" generated code? -- Posted via http://www.ruby-forum.com/.

I''ve gone once through the Agile book and am now attempting my own rails app. I''ve created a table named ''volunteers'' with over 15 columns. The problem is the default list.rhtml that is created with the scaffold, shows all the columns. I only want to show 4 of them with the list view. Where would I start to only return a handfull of columns to the

My code executes fully: <% for column in ModelName.content_columns %> <th><%= column.human_name %></th> <% end %> but it does not pick up any columns in my model''s table that end in "_id". Is this by design? Is there a helper method that will reference the related tables? Or will I need to code the column titles and detail records by

I''m trying to implement a show/hide details function. I have the show part done, but I''m not sure how to get it to hide.

This is the default scaffolding for list.rhtml: [code] <h1>Listing <%= @scaffold_plural_name %></h1> <table> <tr> <% for column in @scaffold_class.content_columns %> <th><%= column.human_name %></th> <% end %> </tr> <% for entry in instance_variable_get("@#{@scaffold_plural_name}") %> <tr> <% for

Hi guru''s out there, Im happilly coding my first rails app, and all goes well. I find myself manually coding in a particular field all the time (company_id), that relates the contact to a company.

Hi, I''m a newcomer to Ruby and to Rails, and am having a problem with character encoding. Now, I know ruby doesn''t handle unicode...but, characters like ? (eacute) and ? (ccedil) are part of the iso-8859-1 charset, so it shouldn''t be a problem, right? But, for some reason, the string functions still seem to hang on those characters. As an example, in a brand new rails

I''m studying the Agile Development with Rails book. In the chapter that first sets up the depot application (page 68), there is this bit of code from a view: <% for product in @products %> <tr> <% for column in Product.content_columns %> <td><%=h product.send(column.name) %></td> <% end %> etc... I am trying to absorb both Ruby and

Hi, I''ve just been pleasantly surprised, again, by how much Rails does for me, but I am *really* surprised. Surprised as in "how the heck did that happen?" I''d really like to understand this and would appreciate any help. Big picture... the user is presented with a form that allows them to select one or more check boxes to record their allergies. The form uses the

Hi all, I''m searching for a method to dynamically build a form. ( false/true field in the DB should automatically be a droplist) If you use "_form.rhtml" it works easy, with only this code in your partial, but uses the extra file, and doesn''t feel profi and flexible. <%= start_form_tag :action => ''create_product'' %> <%= render
