RSpec + FactoryGirl and controller specs - ruby-on-rails

Question

I'm trying to add FactoryGirl support the default scaffolded specs in my controllers and I can't seem to find the correct syntax.
Here's an example test:
describe "POST create" do
describe "with valid params" do
it "creates a new Course" do
expect {
post :create, {:course => valid_attributes}, valid_session
}.to change(Course, :count).by(1)
end
do
Which I replace by:
describe "POST create" do
describe "with valid params" do
it "creates a new Course" do
expect {
post :create, course: FactoryGirl.build(:course)
}.to change(Course, :count).by(1)
end
do
spec/factories/courses.rb
FactoryGirl.define do
factory :course do
association :provider
name "Course name"
description "course description"
end
end
app/models/course.rb
class Course < ActiveRecord::Base
validates :name, :presence => true
validates :description, :presence => true
validates :provider_id, :presence => true
has_many :terms
belongs_to :provider
end
app/controllers/courses_controller.rb
# POST /courses
# POST /courses.json
def create
#course = Course.new(course_params)
respond_to do |format|
if #course.save
format.html { redirect_to #course, notice: 'Course was successfully created.' }
format.json { render action: 'show', status: :created, location: #course }
else
format.html { render action: 'new' }
format.json { render json: #course.errors, status: :unprocessable_entity }
end
end
end
It usually fails with: "ActionController::ParameterMissing: param not found: course" does anyone have any idea?
Thanks!

Answer 1

Try:
describe "POST create" do
describe "with valid params" do
it "creates a new Course" do
expect {
post :create, course: FactoryGirl.attributes_for(:course, provider_id: 1)
}.to change(Course, :count).by(1)
end
end
end
Factory Girl uses attributes_for option to generate a hash of values as opposed to a Ruby object.
