Using variables in partials

[hli24]

Hi Craig,

your package is very good, but I have got a problem when using variable in partials, it works fine when the code is in the root template, but if I try to do the same thing in a partial, the increment doesn't work and throw an exception saying the variable is not defined (or cannot find the variable something like that cannot remember the exact massage)

        {{var index=0}}
        {{index++}}
        {{$.ShiftTimes[index]}}

Hi hli24,

Sorry for taking so long to get back to you - it's been extremely busy at work!

I've had a quick look at the code to refresh my memory as I haven't touched Nettle for a while. Every time a partial is rendered it gets a new template context (this contains the model data and variables etc). I clone the parent context and then overwrite the model with the partials model (if there is one, otherwise it gets the parents model). But then I clear the variables collection - I do this to ensure variables are 'scoped' to their current context. This is likely to be why you are getting the error - although it would be good to see more of the source code causing your particular problem to get more context.

If this is being caused by what I think it is, then I will need to have a think about how to handle this problem better. Are you defining the index variable in the root template and then trying to increment it within the partial?

Thanks,
Craig
