Description

If blank values for parameters are allowed, then one can do thing in templates like

<% !param_name.empty? -%>
<% do_some_thing -%>

This should be a pretty small change in parameter.rb .

that's actually not true, as when saving the host model with the parameters (which is another model), the way to detect if there are new parameters is based on if the value is empty or not.

I'm not sure if that's such a useful feature, as you can also use:

<% if has_variable?("myvar") then %>

Like we discussed on IRC, it would be great if users have the option of having blank values.

We use it in a couple of ways in our templates. (hard to describe, I know)

This is also valid YAML, so it would be great to have that option.

the problem is that the current implementation detect the presence of parameters based on the parameter value... (e.g. it gets deleted if the value is blank).
Patches are welcomed :)
