QUESTION
I built an app using Django 3.2.3., but when I try to settup my javascript code for the HTML, it doesn't work. I have read this post Django Static Files Development and follow the instructions, but it doesn't resolve my issue.
Also I couldn't find TEMPLATE_CONTEXT_PROCESSORS
, according to this post no TEMPLATE_CONTEXT_PROCESSORS in django, from 1.7 Django and later, TEMPLATE_CONTEXT_PROCESSORS
is the same as TEMPLATE
to config django.core.context_processors.static
but when I paste that code, turns in error saying django.core.context_processors.static
doesn't exist.
I don't have idea why my javascript' script isn't working.
The configurations are the followings
Settings.py
...ANSWER
Answered 2021-Jun-15 at 18:56Run ‘python manage.py collectstatic’ and try again.
The way you handle static wrong, remove the static dirs in your INSTALLED_APPS out of STATIC_DIRS and set a STATIC_ROOT then collectstatic again.
Add the following as django documentation to your urls.py
QUESTION
We can use .getA1Notation() to get Notation of a cell Range, for example D3 Could you guys please advise any idea of how to get absolute Notation for a Range, for example $D$3 ?
Thanks in advance,
...ANSWER
Answered 2021-Jun-16 at 01:30Unfortunately, in the current stage, it seems that getA1Notation()
cannot directly return the a1Notation like $D$3
. So, in your situation, how about the following sample script?

QUESTION
I'm trying to read a file with this argument {year}
inside it.
Inside this file there is this string:
SELECT * FROM TABLE WHERE YEAR = {year}
I'd like to read this file with Python
f-strings
to use the query after.
The expected result looks like this:
SELECT * FROM TABLE WHERE YEAR = 2019
I tried this:
...ANSWER
Answered 2021-Jun-16 at 00:02Use str.format
to replace the {year}
.
f-strings are literals and must be an expression. Python will not replace data in string, just because there is a variable of the same name in the bracket notation.
QUESTION
Most of my WordPress websites have a background image in the top fold. These images are the Largest Contentful Paint Element on the page and usually they get loaded last. Somewhere I read that 'Background images are last in line to be grabbed when a page is loaded'. Is it true?
Is it a good idea to use a place holder or image in the place of the background image and then change it later so that the LCP gets loaded quickly like below.
ANSWER
Answered 2021-May-14 at 01:42You don't want to use a placeholder image to prioritize your background images in situations like this, you want to use . That will tell the browser to start downloading the image as soon as possible.
Try adding the following code to the of your page, and then use your background image as normal. It should load much faster:
QUESTION
I have trouble understanding the first line of code inside this implementation of the bsearch function in C. I understand the search algorithm itself and I have played around with this function to get a good grasp of it but I still do not get what
...ANSWER
Answered 2021-Jun-15 at 21:44Within the function you need to find each element in the passed array. However the type of the array is unknown. You only know the size of each element of the array and the starting address of the array that is passed through the parameter base0. of the type const void *
..
To access an element of the array you need to use the pointer arithmetic. But the type void is incomplete type. Its size is unknown/ So you may not use the pointer of the type (const) void *` in expressions with the pointer arithmetic.
Thus this declaration
QUESTION
Turns out you can't have comments in JSON files, and it's a bit awkward to have people refer to some documentation telling them what line to copy/paste in and where in order to achieve this.
I think I can make a python script to copy/paste in one of two package.json files depending on what flags they pass in, but that feels overcomplicated.
I think I can include both dependencies (under different names) but that would create a requirement for both to be available, which is not good either.
Looking for ideas/thoughts on a good way to accomplish this. I have a release and dev version of the same dependency and I often need to swap between the two. Would like to improve the workflow beyond just having a notepad on the side with the two lines pasted in it...
...ANSWER
Answered 2021-Jun-15 at 21:43yarn
and npm
already do this job, why not use them?
Tag the dev versions when you release them
QUESTION
I'm currently using Winsock2 to be able to test a connection to multiple local telnet
servers, but if the server connection fails, the default Winsock client takes forever to timeout.
I've seen from other posts that select()
can set a timeout for the connection part, and that setsockopt()
with timeval
can timeout the receiving portion of the code, but I have no idea how to implement either. Pieces of code that I've copy/pasted from other answers always seem to fail for me.
How would I use both of these functions in the default client code? Or, if it isn't possible to use those functions in the default client code, can someone give me some pointers on how to use those functions correctly?
...ANSWER
Answered 2021-Jun-15 at 21:17
select()
can set a timeout for the connection part.
Yes, but only if you put the socket into non-blocking mode before calling connect()
, so that connect()
exits immediately and then the code can use select()
to wait for the socket to report when the connect operation has finished. But the code shown is not doing that.
setsockopt()
withtimeval
can timeout the receiving portion of the code
Yes, though select()
can also be used to timeout a read operation, as well. Simply call select()
first, and then call recv()
only if select()
reports that the socket is readable (has pending data to read).
Try something like this:
QUESTION
A table example of what I want to happen:
The idea is that in the first column, one could write down the name of the item when it arrives, which would automatically put the date it arrived in the second column. Then when that item is sold, that would be recorded in the third column, which would automatically add the sell date into the fourth column. However, only the third column is working while the first does not input a date anymore
Here is my code:

QUESTION
i'm trying to use public publicRuntimeConfig inside a TypeScript plugin with no success. With JS plugins i have no problems. But now i'm really stuck, i think i don't look at the right place.
The question is how can i access to this config in a TypeScript plugin ?
Here's my nuxt.config.js:
...ANSWER
Answered 2021-Jun-15 at 20:42Nuxt makes the $config
available in two ways: as this.$config
on every component instance, and context.$config
passed to "special nuxt lifecycle areas like asyncData
, fetch
, plugins
, middleware
and nuxtServerInit
" (docs).
It looks like you need to access the $config
outside a component, so you'll need to retrieve it early in the request cycle. In particular, since you're mutating the Vue.prototype
, this feels like a good fit for a plugin in the Nuxt sense, which isn't quite what you've got in your code.
If you put your plugin file in the plugins
directory and reference it from the plugins
array in nuxt.config.js
(see link above for a broader example), you could rewrite it like this to access $config
