Filtering by Negative Attributes

[+MasterSergeantUSMC]

Question for folks please ... on the GC Home page filter options (as well as mobile) as well as other API partners (Cachly for example), I do not see a way to filter by negative attributes. For example, one might want to build a fizzle challenge based on "Not Available At All Times". To be honest, I am not sure a checker could be built within Project GC.

However, if I look at My Geocaching Profile, I have the ability to see progress on Negative Attribute Fizzys.

I am not a well-versed API expert, but I am wondering how that is possible? And then not possible through other filtering efforts.

MyGeocachingProfile (and Project-GC) downloads all the data for all of your finds, and then filters by negative attributes itself. It can then generate statistics, such as the ones you described.

Yes, that is possible: https://project-gc.com/Challenges//84311

A Pocket Query can be used to filter for negative attributes.

I have been told that attributes and their negative versions are allowed in challenges but missing attributes are not allowed. For example, it is not allowed to make an ape challenge for caches that have tree climbing attribute and no climbing gear attribute.

I read that to get the negative attribute you click on the attribute icon twice on the pocket query, but when I do that it just deselects it. What am I doing wrong?

That is correct. Make sure the attribute you are clicking twice on is one that actually has a negative version.

Well that was just unlucky of me! Thank you. I see one now.

Thank you so much. I did not know that.
