            I managed to use type_of in combination with branch. Accessing the item with bracket notation returns a STREAM and I had to get the first item with [0] before using type_of to check for the 'ARRAY' type. This also works if the property is not an array:

            Just change your require to const Guild = require('../../models/Guild');

            You are exporting model as a default from /models/Guild but require it as if its named export like module.exports = { Guild }

            ANSWER

            Answered 2021-Mar-29 at 09:45

            This is not to do with the clocks changing, but the time of the month, and the entirely unhelpful signature of the mktime function.

            When you leave out parameters from a "mktime" call, they are filled in with today's date. In your case, you specified month without day or year, so when you ask for mktime(0, 0, 0, 2); it will fill in today's day and year, and look for the 29th February 2021 - a day that doesn't exist. Since the time library "overflows" dates, this becomes the 1st March.

            The solution is to pass an explicit day to "mktime", as in mktime(0,0,0,$m,1) or to use a less confusing function.

            Using secondary index for .lt() with .filter() in RethinkDB
            Asked 2021-Jan-16 at 16:50

            Currently trying to solve a problem by using RethinkDB to find those objects which has a createdAt date key with less than the given value by using .lt().

            The following query works just fine with .filter() and .lt():

            ...

            ANSWER

            Answered 2021-Jan-16 at 16:50

            filter doesn't use secondary indexes, between should be the best choice here. Just try using r.minval to define the lower key, then it should have the same behavior as .lt(...)

            https://rethinkdb.com/api/javascript/between

            You may also use the special constants r.minval and r.maxval for boundaries, which represent “less than any index key” and “more than any index key” respectively. For instance, if you use r.minval as the lower key, then between will return all documents whose primary keys (or indexes) are less than the specified upper key.

            You need to run rethinkdb first. Enter your venv, and run tmux. Then run rethinkdb inside your tmux shell. This starts the rethinkdb server, and keeps it running. Close the SSH session, and open another one. Try running your code again.
