Hi,

is it possible in Jinja2 template to define possible values for some variable.

Let say I have template config1.j2:

parameter1={{var1 | default(1) }}  
parameter2={{var2 | default(2) }}  
parameter3={{var3 | default(3) }}

So, I would like that to parameter1…3 must be assigned only values 1 or 2 or 3.  
How to achieve that without using “if” statement.

Is it possible somehow to define possible values like is “default” value is defined?
