Sometimes there is no appropriate type to select when creating the schema - is there a general selection or what is the best solution for this?
I am using postgres and therefore enum data types. In some instances I want to import just a selection of options that the data can generate. For instance
Title - Mr, Ms, Mrs (mockaroo is generating honourable, doctor etc)
OR
BookingStatus - pending, confirmed, cancelled
I would use the ‘Custom List’ option in answer to both your questions (unless you are wanting a numeric value, in which case choose Number, or Date/Time chose ‘Datetime’.
With ‘Custom List’ you specify your enum values in a comma-separated list, which would be more suitable than the standard ‘Title’ type if you only want your list of titles, e.g. Mr Ms Mrs.
If this is something that will be used in multiple schemas, or if the list of allowable values is quite long, also consider uploading a single-column dataset (sometimes known as a List) and reference that in the Type field.
