comma_delimited_list parameter returns unicode in parameter list

[Dan Maas]

When running openstack stack show, using the api, or using horizon, comma_delimited_list parameters are rendered as unicode, e.g.

my_parameter: '[u''d74d408f-6a02-46fc-a501-f248e37e4f2f'',u''d74d408f-6a02-46fc-a501-f248e37e4f2g'']'

My expectation was a simple list of strings.

The parameter value is input simply as 'd74d408f-6a02-46fc-a501-f248e37e4f2f,d74d408f-6a02-46fc-a501-f248e37e4f2g'.

This is run against devstack liberty using the latest code from the master heat branch.

Hi Dan,

It looks like you have too many single quotes in your parameter. I tried this template to verify that it works:

Sorry - I mistyped. The parameter value is showing as:

[u'd74d408f-6a02-46fc-a501-f248e37e4f2f',u'd74d408f-6a02-46fc-a501-f248e37e4f2g']

To clarify, in horizon I entered the parameters as:

d74d408f-6a02-46fc-a501-f248e37e4f2f,d74d408f-6a02-46fc-a501-f248e37e4f2g

Attaching screenshot of output.

This also applies to parameters of type json, e.g. {u'foo1': u'bar1', u'foo2': u'bar2'}

    Pretty print parameters in stack-show

    Previously, we were not using the specialized parameter class' __str__
    method to print the parameters in the stack-show output with python
    2.x.

This issue was fixed in the openstack/heat 9.0.0.0b3 development milestone.
