Parameter to detect if field exists? #18

Closed bodywatch-it closed 4 years ago

I'm trying to apply a block with data that may or may not have a given field set. I can use a conditional to display things or not with when , but this causes an error (naturally) when it's evaluating the conditional. I can apply noerr at the template level (I think?), but I'd rather it be done at the block level (or possibly field level). Is this possible, or should I try making a empty_if_missing() function at the passed-in-class object thing?

Yes is it possible. See parameter noerr for fields.

I must be doing something wrong then? 😕

[data;noerr=true;block=landmark;when [data.AS_FPTXYZ] != '']

Is this out of order or otherwise incorrect?

[data;block=landmark;when '[data.AS_FPTXYZ;noerr]' != '']

[data.AS_FPTXYZ;noerr;block=landmark;magnet=landmark]
