QUESTION
I have a dataset with the name of Danish ministers and their position from 1990 to 2020 (data comes from dataset called WhoGovern; https://politicscentre.nuffield.ox.ac.uk/whogov-dataset/). The dataset consists of the ministers name
, the ministers position
, the prestige
of that position, and the year
in which the minister had that given position.
My problem is that some ministers are counted twice in the same year (i.e., the rows aren't unique in terms of name
and year
). See the example in the picture below, where "Bertel Haarder" was both Minister of Health and Minister of Interior Affairs in 2010 and 2021.
I want to create a dataset, where all the rows are unique combinations of name
and year
. However, I do not want to remove any information from the dataset. Instead, I want to use the information in the prestige
column to combine the duplicated rows into one. The observations with the highest prestige should be the main observations, where the other information should be added in a new column, e.g., position2
and prestige2
. In the example with Bertel Haarder the data should look like this:
(PS: Sorry for bad presenting of the tables, but didn't know how to create a nice looking table...)
Here's the dataset for creating a reproducible example with observations from 2010-2020:

and the other for prestige_1
, and join the two results.
QUESTION
I have two ejs forms that when hit, make an HTTP post request to my /api/users/makePicks/:id route. This route hits my controller which updates the Users model in my mongodb with the NFL picks they submitted in the EJS form.
I need this route to create the picks object for each route if they do not exist for that particular week, and if they do exist it needs to update the picks that are already there. The picks are being stored in my User model in an array, this array contains objects for each weeks picks. Currently the code, with much help from Mohammed, is successfully pushing code to to array. But i cannot seem to figure out how to update the picks if an object with a key of that week exists.
My validation is finally working properly. What I mean is we are running a for loop on the picks array, it will console.log true if there is already a matching picks object with for that weeks picks, if the object with a first key value with the current weeks form doesn't exist, it will console.log false and push the new picks to the array.
The only part that isn't working is the if statement nested within my for loop, it is not updating the object if it already exists in the picks.array. But as I said, the validation is working correctly. I suspect the line of code

QUESTION
On my machine I have installed the WSL2 on Windows 10 Pro and a Ubuntu 20.04 LTS distro. I am also using VSCode as editor for programming. I start VSCode in Windows (not in the WSL2 Ubuntu) and there is the possibility to create a new terminal using the profile "New Ubuntu-20.04 (Standard) (WSL)".
Image: Start New Ubuntu 20.04 (Standard) (WSL)
However, this doesn't work as it calls the command "wsl -d Ubuntu-20.04 (Standard)" thus interpreting "(Standard)" as a command to be executed in WSL. This obviously fails as there is no command "(Standard)".
Image: Error message starting the shell
How can I change this profile? Is that possible at all?
As a workaround I can create a new profile in my VSCode user settings and pass the correct argument to the "wsl" command. But then I still have the defective profile entry in the integrated terminal. But I just want to have working entries there.
thanks in advance

QUESTION
I want to pad a 3rd dimension of an array with zeros, here is what I try:
...ANSWER
Answered 2021-May-04 at 07:32Let's start from a remark that Numpy does not support jagged arrays (with different lengths in any dimension).
Another detail to mention is that your source "array" (arr) is actually not any array, but a list of Numpy arrays.
Each element of this list is:
- either a "regular" 2-D Numpy array (if all sizes are the same in each dimension),
- or a 1-D array, containing lists (of different size) and the whole element is an array of object type.
So the proper way to approach the problem is to perform padding 2 diferent ways, according to the type of each row.
Write the following function:

QUESTION
I already tried everything and searched everywhere for an answer but I wasn't successful.
I want to implement a custom function to retrieve filtered values for a Many2one selection list. Usually you would use a domain for that but the domain-options given are not sufficient to achieve my goal.
What function do I have to override to modify the selection list for a given Many2one field?
Thank you, Lars
UPDATE:
Thank you for your answers. I used name_search
to analyze the generated WHERE clause.
Here what I want to achieve and my findings so far:
ANSWER
Answered 2021-Apr-08 at 16:44I think we are on the same page, I would like to sugest the _search method because everytime when you hit on the many2one field this _search method with your written domain in py or xml.
You can override it and do useful.
One thing you need to be aware whenever you are overriding such methods. I'll suggest you to pass context from your field and one condition inside the _search method (on top of all code) so your code will be not affected to other places, because _search method used everywhere.
Thanks
