id_accident id_victim date_accident ROL 123 23A 2021/20/01 PASSENGER 456 12B 2020/19/08 PASSENGER 111 41A 2021/20/01 PASSENGER 222 54B 2020/19/08 PASSENGERI have another dataframe DF2 of the same car accidents and more (id_accident) and VICTIMS in general (could be ROLE_VICTIM = PASSENGER or DRIVERS) and the date of the accident (date1)
id_accident id_victim date_accident ROL 001 23A 2020/20/19 PASSENGER 002 12B 2019/31/12 DRIVER 003 41A 2020/20/12 PASSENGER 004 54B 2020/20/07 DRIVERSo, I need to find for each id_accident and id_passenger if this passenger had a previous accident within last 3 months but now as ROLE_VICTIM =DRIVER.

QUESTION
Why my bot no detect the prefix? it doesn't matter if I put d! or g! or other letter.
I want that my bot only works with the prefix buy I don't know why it doesn't matter what I write.
Then I use :
name: help
,
aliases: h
,
To call the other commands. An if I put g!help or f!help it works when it mustn't works.
ANSWER
Answered 2021-Mar-07 at 18:00Your code only checks to make sure that the command exists, using the length of the prefix to slice the string: (message.content.slice(this.config.prefix.length).split(' ')[0]
)
But it doesnt check to see if the message starts with the prefix: (message.content.startsWith(this.config.prefix)
).
Just add the condition at the start of the message event handler
