[ckan-dev] Most Recent Dataset

[Fabrizio Fornari]

basically, how can I pass argument to package_list.html? It seems that this
way doesn't work. In snippets/package_list.html it says  that the format
should be:

{% snippet 'snippets/package_list.html', packages=c.datasets %}

and that "packages is a list of packages to display."

It seems to me that I should do something like:
plugins.toolkit.render_snippet('snippets/package_list.html',
packages=myListOfPackages)

but it still gives me Error - <type 'exceptions.ValueError'>: invalid
literal for int() with base 10: ''; what should I assign to
myListOfPackages?
