Question

I am trying to execute two helper functions of in a view call the second with the return of the first. I know the following functions properly returns the desired hash:

%p = helper_method0 params[:some_string] #does a request on a third party site which  responds with json data wich is then parsed by yajl and the hash is returned to view

However when I call the following:

- hash = helper_method0 params[:some_string] #does a request on a third party site which  responds with json data wich is then parsed by yajl and the hash is returned to view
%p= helper_method1 hash #Literally is just returning the input parameter

I receive the following error message

 Found multiple JSON objects in the stream but no block or the on_parse_complete callback was assigned to handle them.

How do I call a method with an input parameter as the return of another method from the view?

Answer 1

What you are doing is perfectly correct 🙂

And you could also do:
(if you want to save bytes and variables)

%p= helper_method1( helper_method0 params[:some_string] )

---

But anyway…
This error sounds like a problem in the json parser… are you using Yajl?

I have seen this issue when using Yajl like this:

parser = Yajl::Parser.new
hash = parser.parse(some_string)

What worked for me was to use the Yajl class method like this:

Yajl::Parser.parse(some_string.strip)

I hope this helps 🙂
