QUESTION
Been fighting with this one for days. Hopefully, I'm being thick and there's a semicolon missing from somewhere.
I've been trying to setup a reference to my REST-enabled SQL (RESS) on my local box, and Apex refuses to acknowledge it.
I'm using the article at https://docs.oracle.com/database/apex-18.1/HTMDB/rest-enabled-sql-creating.htm#HTMDB-GUID-0906921E-AF79-49D4-B909-1C090F805D9D, which seems quite straightforward.
Before you ask:
- Yes, I've enabled the schema for REST
- Yes, I've enabled RESS in the defaults.xml file
- Yes, I've tested the RESS away from APEX, using a curl command like
curl -i -X POST --user testuser1:testuser1 --data-binary "select sysdate from dual" -H "Content-Type: application/sql" -k http://localhost:8080/ords/hr2/_/sql, and it works.
Then in APEX->Shared Components->Data Sources->REST Enabled SQL, I've setup this reference:
and it uses these credentials:
However, when I initially created the reference, and when I test it, I get the following message:
What on earth am I doing wrong? Using Oracle APEX 21.2.0 and ORDS Version 21.4.1.r0250904
...ANSWER

QUESTION
On Gitpod, my NextJS frontend is trying to fetch the list of objects which contain "product names", "prices" and "images" from my Django Rest API backend. Then, my NextJS frontend can get the list of objects which contain "product names" and "prices" but not "images" so my NextJS frontend cannot get only "images" as shown below:
("product names" such as "boots 4", "boots 3" ... and "prices" such as "£12.10", "£10.50" ... are displayed but not "images")
This is my desired output with "product names", "prices" and "images":
On Gitpod, both my NextJS frontend on port 3000 open (private) and my Django Rest API backend on port 8000 open (private) are running:
And my NextJS frontend uses this Rest API call with "localhost" as shown below to get the list of objects which contain "product names", "prices" and "images":
...ANSWER
Answered 2022-Feb-22 at 01:19You should make the port 8000 for your Django Rest API backend "public" to get the list of objects which contain "product names", "prices" and "images":
Finally, you can get the list of objects which contain "product names", "prices" and "images":

I am trying tot write a file and remove the .pdf extension and replacing it with .xml extension.
But now, if the filename starts or ends with the letter p, it gets removed.

QUESTION
I have a simple modbus device (Ebyte MA02-XACX0440) that I'm trying to learn how to work with. Using a third party GUI called serial port monitor (www.serial-port-monitor.org) I was able to more or less "stumble upon" the proper hexadecimal inputs needed to turn a discrete output on and then off. I don't understand these terms of unit, address, coils, registers, etc. and how it all relates when it comes to the hexadecimal aspect. To break down what I think I know so far (below is the hexadecimal string that will turn the first discrete output 'ON'):
0x20 0x05 0x00 0x00 0xFF 0x00 0x8A 0x8B
I know 0x20 is the device address in hex. The documentation of the Ebyte device stipulates that the default hardware address is '31' and that the first software address is '1'. If I understand that correctly, that means my first physical modbus device on the line has an address of '32', and if I were to put additional modbus devices on the line (either RS485 or TCP(?)) that the next device would be '33' and so on.
I know that the next byte 0x05 is 'write coil'.
I don't know what the next two bytes of '0x00' and '0x00' refer to.
The next two bytes are essentially on/off with '0xFF00' being 'ON' and 0x0000 being 'OFF'.
The final two bytes are simply the CRC checksum.
So up to this point I can get my DO (Discrete Output) to turn on, open up, and light up an LED as a simple proof of concept. Now when I take that approach over to using the pymodbus library (my ultimate goal), things don't seem to line up.
I am able to connect to my device using the pymodbus REPL using
...ANSWER
Answered 2022-Feb-10 at 20:06The Modbus specs describe the protocol and are worth a look. I use this online Modbus parser when I want to quickly parse a command; it's output for the string of bytes you give (20 05 00 00 FF 00 8A 8B) is:
The slave address indicates which device on the bus you wish to communicate with. This is set on the device (you cannot just add devices and expect things to work). The method used to set slave ID's differs from device to device (some have a utility to do this, some use switches or settings via their own user interface, and some have this hard coded). Your device (Ebyte MA02-XACX0440) defaults to 32 but this can be changed using the DIP switch on the device (this is covered in the manual).
You are using function code 5 - 'Write Single Coil'. Coils are bits so can be on or off.
The 'output address' indicates which coil on the device you wish to write to. The meaning of this address varies from device to device (generally there will be a table in the documentation that explains this). For your device this is in table 7.1 ("Register list") in the manual.
The value is what to write. For the 'write single coil' function this must be one of two values:
value meaning 0x0000 Off 0xFF00 OnAll other values are invalid. However many libraries (incluing pymodbus) will handle this detail for you allowing you to pass True/False.
Putting this all together you will need something like:
QUESTION
I'm trying to find a solution for the following task, but I’m stuck. Please for a solution. The code is working fine for counting exact string matches, but what I’m trying to achieve is to find and count words if they are not the same using regex pattern or like operator and wildcard combined, any solution acceptable for example:
Add.ress
add/ress
add-ress
add ress
add*ress
add!ress
add\ress
etc.
Count=6
Only if input textbox.text is "add?ress" count should be 6 (“add ress” excluded because of space ), to make it clear input can be any word but if ? is in between then this rule should apply. the question mark (?) can by anything except Letters and numbers else if textbox.text is “add ress” count=1 or if textbox.text is add-ress count=1. I would like to use ? for any char in between string if it appears on search textbox.
Thank you.

QUESTION
I have extracted id, username, and name for 100 followers for 102 politicians using Tweepy. The data is stored in a JSON file named pol_followers. Now I wish to append id and username and save it as a CSV file using the function below. However, when using the function in the last line append_followers_to_csv(pol_followers, "pol_followers.csv") I get the error seen at the bottom.
ANSWER
Answered 2022-Jan-06 at 20:00You seem to have wrapped your JSON object in a list, so instead of getting the 'data' bit of the JSON, you are getting the 'data'th element of a list when you are iterating in your append_followers_to_csv function, which you can't do in python. Try removing the square brackets around the JSON or making it for ids in pol_followers[0]['data'].

QUESTION
Background: I'm using the metropolis theme which slides background colour is the same as the default background colour of the displayed code in chunks in beamer.
Problem: I want to change the representation of the chunks output. There should be a different type of representation for source-code & results to distinguish them. The source-codes background should be in a slightly darker grey than the metropolis slides background and the results should be surrounded by a black line as a frame.
What I already tried: This threat answers my question for HTML-outputs (YAML: output: html_document), but I didn't figured out how to get it working in beamer_presentation.
This is my "minimal" working example:
...ANSWER
Answered 2021-Oct-21 at 20:02you can change the colour of the code with
\definecolor{shadecolor}{RGB}{148,248,248}(choose whatever colour you like)adding a frame around the output is a bit more hacky. rmarkdown automatically loads all kinds of packages to format verbatim code, like the
fancyverbpackage, but then it goes ahead and ignores them and uses the normal latexverbatimendvironment for the output. Makes no sense at all, but you can use this dirty hack to redefine the environment like this to use the fancyverb package which provides an option to add a frame:
