n00b question on passing parameters to a webservice

rubyonrails-talk
1

Let us say I have a webservice method: api_method :login, :expects => [:name=>:string, :password=>:string], :returns => [:int]

defined as:

def login(name, password)

   #do something here and returns an int end

how do exacly pass it the two parameters from the client? I tried:

- @ws_client.login('user', 'mypwd')

- @ws_client.login({:name =>'user', :password=>'mypwd'})

- @ws_client.login(['a','b'])

No matte what, I always get: "wrong number of arguments (1 for 2)"

When edit the method to accept just one parameter, and call it with: @ws_client.login('user') everything runs fine.

I'm sure I'm missing something _very_ obvious. Please help....

Thanks in advance

Have you tried this?

@ws_client.login(:name =>'user', :password=>'mypwd')

I would have thought this would have worked (I don't know why it doesn't):

@ws_client.login('user', 'mypwd')

..but these won't work :

@ws_client.login({:name =>'user', :password=>'mypwd'})

@ws_client.login(['a','b'])

..because Ruby sees the Hash and Array as a single argument

Thank you! I'll try as soon as possible.

that should be :expects => [{:name => :string}, {:password => :string}]

then you should be able to just do @ws_client.login('user', 'password')

Ok, the lucky combination was:

:expects => [{:name => :string}, {:password => :string}] #in the service definition

@ws_client.login({:name =>'user', :password=>'mypwd'}) # in the method call.

Now it works beautifully. Thanks a lot, everyone!
