Rails responds with status code 406 - ruby-on-rails

Question

I have been working on a test for my function inside Ruby on Rails. However, the test (which expects a status code of :success) fails after receiving a status code 406. Here's the exact failure log:
Failure: Expected response to be a <:success>, but was <406>.
test_should_post_comment_through_token_successfully(CommentControllerTest)
test/functional/comment_controller_test.rb:271:in `block in <class:CommentControllerTest>'
I read a little about the 406 response, and found out that it stands of "Not Acceptable". so I tried setting the Accept, Content-Type, Accept-Language and Accept-Charset headers but I have had no luck.
Here's the code for my test:
test 'should post comment through token successfully' do
#params = {
id: 1,
body: "Test Comment",
username: "Bob"
}
#headers = {
"Accept" => "application/json",
"Accept-Language" => "en-US",
"Accept-Charset" => "utf-8",
"Content-Type" => "application/json",
"Token" => "abcdefg12345"
}
get :create_by_token, #params, #headers
assert_response :success
end
The create_by_token function inside the controller:
def create_by_token
#node = Node.find params[:id]
#user = User.find_by_username params[:username]
#body = params[:body]
#token = request.headers['Token']
p request.headers["Accept"]
p request.headers["Content-Type"]
p request.headers["Token"]
if #user && #user.token == #token
begin
#comment = create_comment(#node, #user, #body)
msg = {
status: :created,
message: "Created"
}
respond_to do |format|
format.xml { render xml: msg.to_xml }
format.json { render json: msg.to_json }
end
rescue CommentError
msg = {
status: :bad_request,
message: "Bad Request"
}
respond_to do |format|
format.xml { render xml: msg.to_xml }
format.json { render json: msg.to_json }
end
end
else
msg = {
status: :unauthorized,
message: "Unauthorized"
}
respond_to do |format|
format.xml { render xml: msg.to_xml }
format.json { render json: msg.to_json }
end
end
end
My route:
post '/bot/comment.:format', to: 'comment#create_by_token'
Am I missing something crucial? How do I go about solving this issue?
I would be happy to provide any other information you would need.

Answer 1

Seems this might be an error with respond_to do block. Kindly check with the routes whether you have configured as resources or resource.
Do update to resources than singular which will help with respond_to do block.
You can also try update your routes as/;
resources :samples, defaults: {format: :json}

Answer 2

Oh, stupid me. I realized that among all the params I was passing, the format was also being passed inside the URL. However, as in the test I was not mentioning a URL which I could pass in the format as the suffix (.xml or .json), I would have to mention the format inside the params explicitly. Here's the updated test code:
test 'should post comment through token successfully' do
#params = {
id: 1,
body: "Test Comment",
username: "Bob",
format: 'json'
}
#headers = {
"token" => "abcdefg12345"
}
post :create_by_token, #params, #headers
assert_response :success
end
Kudos #Sowmiya for leading me to this conclusion. Your answer was not exactly the solution I needed, but it provoked me to think.
