QUESTION
I am working on a project in which I need to post a new Course to my API. I tested this with POSTMAN and API works just fine, however when I try to post data using react fetch data is corrupted. While sending single strings like dishName: "pizza" works just fine and is shown in database I cannot manage to send an array of objects. I tried to do it in many ways like:
...ANSWER
Answered 2021-May-27 at 21:44You are setting the ingredients state as a string, so you are basically 'stringify' a string which will result in JSON SyntaxError. If you want to send an array that way you must specify the array bracket [ and ] in order to make it a valid array.
To solve it just change:

I have a dataframe testlist that has three columns: "Time Point" "G1" and "G2"
I run this ggplot line on it, having "Time point" as y-axis.
ANSWER
Answered 2021-May-20 at 03:08The difference in failure is because one contains zeros and the other doesn't. NaNs from taking the log of a negative number are removed in the density plot function but -inf from log of zero isn't. The ggridges layer fails because it uses the standard deviation to set the bandwidth, and the standard deviation when the vector contains -inf is NaN. There's no reason to not remove negatives/zeros if you want to use a log transformation, but you could keep it as is if you input the arguments from and bandwidth into the ggridges geom.

Using RegExReplace() with the MyListBox variable as the haystack and "\|" as the needle. See this interactive for an explanation of this particular RegEx needle.
Saving the replaced version of the String in a variable called NewStr gives us this line of code:
NewStr := RegExReplace(MyListBox, "\|" , Replacement := ", ")

Make sure to compare your values safely.
If your value is not in the right type or has spaces or unwanted chars, this c.state == val might not work.
You can use the trim function to compare your value safely:
c.state.trim() == val.trim()

QUESTION
I only want to allow access to my server from one domain. Lets say my domain is called "mydomain.mydomain.com" (yes, it is a subdomain).
Normally I would write everywhere server_name mydomain.mydomain.com, but I changed it to a non-existing domain and I can still enter the website? Why is my website working also from other domains? I know nginx is normally using the first server-block if no server_name is found, but my first server-block is my catch-all non-existing domain block. I defined server_name _; and default_server, but still, my website is working.
I have the following configuration:
...ANSWER
Answered 2021-Apr-19 at 04:34You are listening to the IpV6 network socket in your server blocks where you change domain to non-existent. Since there are no other such server blocks, they are the default for those IPv6 ports.
Note that your first server block is default only for IPv4 network socket listen 80 default_server;.
Thus the behavior can be explained only by the fact that you are connecting/testing over IpV6.
To avoid inconsistency, use default_server for all your listen options. E.g. in the first server block add default server for IPv6 too:
