Hi.
I try to create an integration test for a form that updates two models
(order and floorplan), Creating a functional test for this situation
works fine, however I cannot build an equivalent integration test.
My master model (order) contains
has_many :floorplans
accepts_nested_attributes_for :floorplans
that makes it possible to assign floorplans directly to order
then I have a form (new.html.erb) containing
<% form_for(@order, :html => {:multipart => true}) do |f| %>
<% f.fields_for :floorplans do |floorplan_fields| %>
<%= floorplan_fields.file_field :file_upload %>
<% end %>
<% end %>
I only want my form to contain one floorplan object to be created, so
in the controller I have
def new
@order = Order.new
@order.floorplans.build
end
In the functional test I can now verify what I see in the browser:
test "should create order" do
assert_difference('Order.count') do
post :create, {
:order => {
:floorplans_attributes =>
[{:file_upload => fixture_file_upload('files/empty', 'image/png')}
]
}}
end
This works fine, but if I try to test this in an integration test I
can't test this, I have tried both
post "orders/create", {:order => {
:floorplans_attributes =>
[ {:file_upload => fixture_file_upload('files/empty', 'image/png')} ]
}}
and
post "orders/create", {:order => {
:floorplans_attributes_0_file_upload =>
fixture_file_upload('files/empty', 'image/png')
}}
but it doesn't work.
The first attempt just serialises the list [ {:file_upload =>
fixture_file_upload('files/empty', 'image/png')} ] into a string when
creating the HTTP POST request and produces
Hash or Array expected, got String
("file_upload#<ActionController::TestUploadedFile:0x7f47ee571f60>")
The second one fails with
unknown attribute: floorplans_attributes_0_file_upload
What to do?
