ruby on rails - How to call the create action from the controller in RSpec -

i have controller create action creates new blog post, , runs additional method if post saves successfully.

i have separate factory girl file params post want make. factorygirl.create calls ruby create method, not create action in controller.

how can call create action controller in rspec? , how send params in factory girl factories.rb file?

posts_controller.rb

def create   @post = post.new(params[:post])   if @post.save     @post.my_special_method     redirect_to root_path   else     redirect_to new_path   end end 

spec/requests/post_pages_spec.rb

it "should run special method"   @post = factorygirl.create(:post)   @post.user.different_models.count.should == 1 end 

post.rb

def my_special_method   user = self.user   special_post = post.where("group_id in (?) , user_id in (?)", 1, user.id)   if special_post.count == 10     differentmodel.create(user_id: user.id, foo_id: foobar.id)   end end    

end

request specs integration tests, using capybara visit pages user might , perform actions. wouldn't test create action request spec @ all. you'd visit new item path, fill in form, hit submit button, , confirm object created. take @ railscast on request specs great example.

if want test create action, use controller spec. incorporating factorygirl, this:

it "creates post"   post_attributes = factorygirl.attributes_for(:post)   post :create, post: post_attributes   response.should redirect_to(root_path)   post.last.some_attribute.should == post_attributes[:some_attribute]   # more lines above, or remove `:id`   #   `post.last.attributes` , compare hashes. end  "displays new on create failure"   post :create, post: { some_attribute: "some value doesn't save" }   response.should redirect_to(new_post_path)   flash[:error].should include("some error message") end 

these tests need related creation. in specific example, i'd add third test (again, controller test) ensure appropriate differentmodel record created.
