...ANSWER
Answered 2021-Nov-23 at 08:53I 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

command, i keep on getting that error and this is my code:
ANSWER
Answered 2021-Jun-22 at 13:24Just 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 }
QUESTION
I am trying to get the second last value in each row of a data frame, meaning the first job a person has had. (Job1_latest is the most recent job and people had a different number of jobs in the past and I want to get the first one). I managed to get the last value per row with the code below:
first_job <- function(x) tail(x[!is.na(x)], 1)
first_job <- apply(data, 1, first_job)
...ANSWER
Answered 2021-May-11 at 13:56You can get the value which is next to last non-NA value.
QUESTION
I've been using the following function fine until the other day when the clocks went forward:
...ANSWER
Answered 2021-Mar-29 at 09:45This 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.

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
andr.maxval
for boundaries, which represent “less than any index key” and “more than any index key” respectively. For instance, if you user.minval
as the lower key, then between will return all documents whose primary keys (or indexes) are less than the specified upper key.
QUESTION
I'm following this guide here https://github.com/flaree/Flare-Cogs/tree/master/dankmemer. I got to the import rethinkdb part but I get this error when running the r.connect('localhost', 28015).repl() command. Been searching yesterday for a fix but couldn't find one.
...ANSWER
Answered 2020-Oct-13 at 20:43You 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.
