In my rails app Users and Schools can create courses, and each course has one syllabus.
in my course model:
belongs_to :hostable, polymorphic: true
has_one :syllabus
syllabus:
belongs_to :course
school (and user):
has_many :courses, as: :hostable, :dependent => :destroy
My routes are currently set up as follows:
resources :users do
resources :courses
member do
get :attending, :memberships
end
end
resources :schools do
resources :courses
member do
put :apply, :enroll
end
end
resources :syllabuses
In my syllabuses controller I have:
def create
@course = Course.find(params[:id])
@syllabus = @course.build_syllabus(params[:syllabus])
if @syllabus.save
redirect_to @course, notice: 'Syllabus was successfully created.'
end
end
my courses controller has this:
def show
@course = Course.find(params[:id])
@school = Course.find(params[:school_id])
@title = @course.title
unless @course.syllabus
@syllabus = @course.build_syllabus
end
end
and my course view page has
<%= form_for (@syllabus) do |f| %>
<div> <%= f.label :syllabus %> </div>
<%= f.label :name %>
<%= f.text_field :name %> </br>
....
<%= f.submit "Save Changes" %>
<% end %>
but when I try to create a syllabus from a course page inside of a school I get:
"Couldn't find Course without an ID"
What am I doing wrong? How could I reconfigure my routes/models so that both Users and Schools can create a course, and then from within the course a syllabus can be created? I tried nesting the syllabus model under the course model with javascript but I had a few problems.
Try nesting syllabus in your routing,
resources :courses do
resource :syllabus
