Problem executing self.Web.Notify

Back

Hi guys,

 

Anybody else run into problem executing self.Web.Notify method in Python?

2013-10-07 00:00:00 An unknown error occurred .<class 'AttributeError'>

 I've identified the line of code in following algo that bombs is the one sending the self.WebNotify message with a data object as the second argument.

self.Notify.Web("http://www.tradejolt.com/wordpress/qj_sms_forwarder.php",self.signal)

Please note: although this message will only get sent in live mode, it should still gracefully exit without an error in test mode. That is not happening.

Just removing all the try-catch layers I got a nice exception.

During the algorithm initialization, the following exception has occurred: AttributeError : 'BasicTemplateAlgorithm' object has no attribute 'signal'
at Initialize in main.py:line 14
at testNotify in main.py:line 24
AttributeError : 'BasicTemplateAlgorithm' object has no attribute 'signal'

After initializing the signal object there was an issue with that type though, so I played and got it working with: 

self.Notify.Web("http://www.tradejolt.com/wordpress/qj_sms_forwarder.php", "simple data" )

I don't think it'll work with complex objects but it does support strings/ints/floats. Recommend serializing your object in python first then passing the string through.

Hi Jared,

 

Thanks. That put me on the right track. Here's the finished version, which also handles serializing the complex data object with a string and a timestamp. Hope that can help someone else.. Now I wll go run it live, and see if I get sms forwarder does its job.
