QUESTION
It seems that all the recommended approaches I see on the internet are to use the UserManager.CreateAsync() method to create users.
What are the downside of using only ef core dbContext?
Say that I have a TimeZoneInfoId column in AspNetUsers.
ANSWER
Answered 2022-Apr-15 at 08:06First of all, UserManger is another level of abstraction. Usually it's used with EF-based user store, but you may implement ANY store you want.
So if you use UseManager project-wide and at some development stage you decide that you want to switch current EF-based user store to something else, the only thing to do is to replace IUserStore in your UserManager. If you go the way you provided (calling db directly) - you'll be supposed to refactor EVERY place where you managed the user.
User manager takes care about few more things, for example: updating security stamps / normalization or validation - it's very important to know, that you can modify every aspect of UserManager - the only thing you have to do is to switch UserManager abstraction to another one - just like in case of IUserStore.
To sum up, UserManager work's like a good glue for many components which allows you to manage users. In default it uses good default implementations but it's very easy to adjust it any way you need.

QUESTION
From my original data frame, I used the group-by to create the new df as shown below, which has the natural disaster subtype counts for each country.
However, I'm unsure how to, for example, select 4 specific countries and set them as variables in a 2 by 2 plot.
The X-axis will be the disaster subtype name, with the Y being the value count, however, I can't quite figure out the right code to select this information.
This is how I grouped the countries -

I am trying to move a label on a form with CSS, when focus on the and select a different option than the first one, the problem is that when I select a different option than the first one the label goes back to its original position but I want it to lock in the previous position if the user chose a different option, but it is overlapping just like this:
This is the code I have, thanks
CSS:
select:not([value='opt1']),
select:focus ~ label{
top: -25px;
font-size: 1.3rem;
transition: all 0.2s 0s;
opacity: 0.8;

...ANSWER
Answered 2021-Oct-11 at 15:39I think JavaScript is necessary in this case because option[value] must be used instead of select[value], which does not allow you to target label in CSS (it's in the parent level). A very similar option to what you already have is this: add onchange = "this.dataset.value = this.value" to your select and change select:not([value='opt1']) to select:not([data-value='opt1']) ~ label. Like that:

I have two vectors here. One is all the data about population for various countries:
...ANSWER
Answered 2021-Oct-03 at 16:26It would be easier to read with read.table with delimiter space. But, there is an issue with space as the 'Country' may have multiple words and this should be read as a single column. In order to do that, we can insert single quotes as boundary for the Country using sub and then read with read.table while specifying the col.names as 'v2'
