> I have checked my application's controllers
(app/controllers/application_controller.rb and
app/controllers/parts_controller.rb) and controller spec
(spec/controllers/parts_controller_spec.rb) and found no before filter that
is preventing the :update_attributes message from being received by Parts.
Below is what my spec/controllers/parts_controller_spec.rb looks like:
------- Source code, spec/controllers/parts_controller_spec.rb starts
-----------------------
require 'spec_helper'
describe PartsController do
let(:part){
mock_model('Part').as_null_object
}
before do
Part.stub(:new).and_return(part)
end
it "creates a new part" do
Part.should_receive(:new).
with('title' => 'HKS boost controller').
and_return(part)
post :create, :part => { 'title' => 'HKS boost controller' }
end
context "saves the new part object successfully" do
it "sets the flash with a success message" do
post :create
flash[:notice].should eq('Part was successfully created.')
end
it "redirects the user back to the Parts index page" do
post :create
response.should redirect_to( :action => 'index' )
end
end
context "the new part object fails to save" do
before do
# sabotage and make the save fail
part.stub(:save).and_return(false)
# call the create method which will have save in its process
post :create
end
it "assigns @part with the data from db (or a blank one if it's the
first time" do
assigns[:part].should eq(part)
end
it "renders the 'new' template again" do
# test that the template, 'new' is rendered. Of course, for this
# work, the part's attribute variable values must be passed to
the
# view for rails to successfully render the template
response.should render_template('new')
end
end
context 'saves updates to an existing part object successfully' do
it 'does its job in saving the update' do
Part.should_receive(:find).with(1).and_return(part)
Part.should_receive(:update_attributes).with('title' => 'Brake
pads').and_return(part)
put :update, :id => 1, :part => {'title' => 'Brake pads'}
flash[:notice].should eq('Part was successfully updated.')
end
end
end
------- Source code, spec/controllers/parts_controller_spec.rb ends
-----------------------
Do you have any good tutorials which illustrate the update message which I
could refer to?
I've been digging but can't find anything helpful :(
thanks for your help :)
