how do i remove an attribute+value from database? [[:db/add [:app/form id] :form/stage nil]] does not work because it does not accept nil as a value.

[:db/retract entity-id attribute value]

i have to know what the value is?

[[:db.fn/retractAttribute eid attribute]]

There is also a built-in function to retract an entire entity, aptly named :db.fn/retractEntity

i want to keep the entity

just one attribute

then it's the above :db.fn/retractAttribute

@niko963 thank you
