QUESTION
I want to check if item has particular column in database. I'm using Parse Dashboard and value in this column is type String
and there is not empty string but (undefined)
. And this is returning null value. So I want to check if actual column does exist.
So I've used ParseObject.containsKey("column_name")
, but this is returning false
. I know, that value in this column is empty/null, but I want to check not value, but if that column actually exist before I can put something there.
According to documentation, this function should do exactly what I want, but it obviously doesnt work.
I've checked objectId
of this item and I've checked this item in database and object with this exact id is in Class table which contains column with exact name.

Answered 2018-Dec-18 at 19:54The containsKey
method on a ParseObject
will tell you only if a value has been set for that instance, not if the class can accept that property. What you want to do is inspect the Schema.
Operations on the schema (including reading) require the master key, so it is not appropriate for a client SDK like Android to access the schema directly.
I don't know your use case, as it seems unlikely that your clients would need to know this, but if you wanted a client to know the answer, you'd have to set up a cloud function that could use the master key to inspect the schema.
QUESTION
I am updating some previously working cloud code to the new Parse Server. I have updated it with the new method of passing useMasterKey.
The query part appears to be working as the resultingStations array gets populated, but the delete is failing.
