My first attempt at working with a new has_many relationship is throwing an error in the view when I try to create a new 'rcost' instance linked to a 'resource' (each resource can have multiple costs):
"undefined method `rcosts_path' for #<ActionView::Base:0x715bc60>" Here is the view (new.html.erb) code that appears to be causing the error (I do not reference rcosts_path anywhere in the view): <% form_for(@rcost) do |f| %> Here are my model declarations: class Resource < ActiveRecord::Base has_many :rcosts end class Rcost < ActiveRecord::Base belongs_to :resource end Here is my route declaration: map.resources :resources, :has_many => :rcosts I first tried the build method in my rcosts_controller: @rcost = @resource.rcosts.build Then tried new and manually setting the foreign key: @rcost = @resource.rcosts.new @rcost.resource_id = @resource.id But neither worked. I'd really appreciate it if someone could tell me what is going wrong and how I can create a new rcost instance associated with an existing resource instance. Thanks in advance!
