QUESTION
I'm currently using the prompt package in Node to get user input on the command line, however, I would like to return a variable from prompt.get - how would I store the return variable/where can I access it from? I'm relatively new to Node.
...ANSWER
Answered 2021-Jun-15 at 06:51You could initialize the variable outside the callback, and then set the variable inside of the callback:
QUESTION
Is there a method in R, to substitute the values of a vector using a dictionary (2 column dataframe with old and new value)
The only method I know is to extract the old value into a dataframe and merge it with, what I call,the dictionary (which is a two column dataframe with old and new values). Afterwards reassign the new value to the original old value. However, it seems when using merge (at least since R v4.1, the order of the x value is not maintained, so I am using join now which keeps the original order of dataframe x intact. I am thinking that there must be an easier way, I just have not found it. Hope this is understandable, I appreciate any help.

...ANSWER
Answered 2021-Jun-14 at 09:42You could use a named character vector as a dict for replacement by unquoting with !!!
inside of dplyr::recode
. If you have your "dict" stored as a two-column dataframe, then tidyr::deframe
might be handy.
QUESTION
One thing which I have learnt from working with Identity Server is that, out of the box, ASP.NET Core Identity does not play too well with Identity Server. Refer to this question.
ASP.NET Identity contains a way of ejecting users where a particular user's data has changed. This is regulated by the SecurityStamp column of the aspnetuser table. When the stamp changes, the next time the cookie is validated, it fails validation.
This is turned on by default and it is the reason why it does not work well with Identity Server.
You end up with users getting kicked out erratically. And when you expect it to kick users out, it doesn't.
Anyhow, how do you disable this feature of ASP.NET Identity???
There is a column on the UserManager called SupportsUserSecurityStamp.
However, it is a "getter" only and I cannot find any configuration setting for switching that to return false
.
It seems to me that the only way is to derive from the UserManager class and make that property only ever return false
.
That feels like a hack. Especially when you look at the code for that property on Github:
...ANSWER
Answered 2021-Jun-14 at 00:24I turned the SecurityStamp
feature off, as described in the question.
So, I created a class which inherits from the UserManager
class.
Should look something like this:

I'm having some issues with the "Promise.all" method. Bascially, I have an array of URL (here is a simple one if you guys want to test :
...ANSWER
Answered 2021-Jun-12 at 16:03Your urlArray
is an array of plain strings, not an array of requests. You never actually make any network requests in your code - you don't have any Promises.
Map the array of request URLs to an array of Promises first.
QUESTION
I am trying to update multiple rows in a table using Laravel Eloquent. But unfortunately, the code below updates only one row. Please what am I doing wrong? Could someone help out please? Cheers
...ANSWER
Answered 2021-Jun-12 at 07:08I think you need to rethink what you are storing. It seems like earning
is a derived value based on other values in the database and it's a bad idea to store it directly.
If you must (for whatever reason) do this then you can try something like:

So i am trying to connect multiple users to a room where video can be shared, but I keep getting an error whenever I join a room which is Cannot read property 'emit' of undefined
which is thrown for the socket.to(roomId).broadcast.emit('user-connected', userId)
line. I'm not sure what is causing this, and any help would be great. Cheers.
ANSWER
Answered 2021-Mar-21 at 13:01To broadcast to all clients in a particular room, just use socket.to(roomId).emit(...)
. You don't need to use the .broadcast
property.

The problem was that I try to run it using a TestContainer and I can't watch any logs.

QUESTION
I have a simple for loop in c++
...ANSWER
Answered 2021-May-29 at 09:06The condition (itrA != a.end()
is true if itrA does not reach the end.
While (itrA == a.end()
is true if itrA does reach the end.
The correct condition for both A and B reach the end is (itrA == a.end() && itrB == b.end())
QUESTION
I am trying to loop over a Xpath in Scrapy which looks like this:
...ANSWER
Answered 2021-Jun-10 at 14:05this XPath:
'normalize-space(//div[@id="Content"]//div[@id="programDetails"]//div[@id="selfReportedProgramDetails"]//div[@id="hoursOfOperation"]//span[@class="hoursItem"]//span[@class="times"]/text())')
:
will give only one result because of the normalize-space()
function with all whitespace collapsed.
So to get the actual text-nodes for those spans remove the normalize-space around your XPath.
The second XPath starts with double slash, meaning, it will search from the root all nodes. To search from current context use the .
