Hi,
quite new to rails and ruby... so still wondering how does it
work.. 
i have three tables structured as follow: 1) categories 2) recipes 3) steps
where steps belongs_to recipe recipes belongs_to category
and category has_many recipes recipe has_many steps
i've created the standard scaffold for the three above... everything went ok, i've modified the models for the constraints on the FKs, i've modified the views to add a select dropdown to show in the recipe edit/new form the categories, and in the step edit/new form the recipes.
in the _form.rhtml for recipes i've: <%= select("recipe", "category_id", Category.find(:all).collect {|c| [c.name, c.id] }) %></p>
and in case of editing it shows the right category preselected.
in the _form.rhtml for steps i've: <%= select("step", "recipe_id", Recipe.find(:all).collect {|c| [c.title, c.id] }) %></p>
in this case the preselection doesn't work...
now to create a step inside a recipe i've a link in the main recipe edit/show page like that: <%= link_to "Create new Step", {:controller => "step", :action => "new", :recipe_id => @recipe} %>
that create a link like this one (assuming i'm viewing the recipe id#2): http://localhost:3000/step/new?recipe_id=2
hope i'm clear enough... how all this can works? what i'm doing wrong? what's the logic to follow?
thanks for any suggestion really appreciated.
