Here is my code: ...TypeError: items is undefined
ANSWER
Answered 2021-Jun-07 at 14:28You are using axios, and axios has a predefined schema for HTTP responses, you can take a look at here- https://axios-http.com/docs/res_schema
For your case, you need to correct the callback inside your .then()
of the axios API call, something like this -
QUESTION
I'm reading K.N.King C programming and I have an issue about it.
I'm solving project 5, chapter 12 which is modify project 14 from chapter 8 by using the pointer .
Project 8.14
Write a program that reverses the words in a sentence:
Enter a sentence: you can cage a swallow can't you?
Reversal of sentence: you can't swallow a cage can you?
...Hint: Use a loop to read the characters one by one and store them in a one-dimensional char array. Have the loop stop at a period, question mark, or exclamation point (the "terminating character"), which is saved in a separate char variable. Then use a second loop to search backward through the array for the beginning of the last word. Print the last word, then search backward for the next-to-last word. Repeat until the beginning of the array is reached. Finally, print the terminating character.
ANSWER
Answered 2021-Feb-09 at 16:28The second loop looks too complicated to me. You are required to scan the string backwards and print every word found, right? But you're not required to retain the whole sentence...?
So we can replace every space character with zero, thus terminating each word.

QUESTION
I normally use the United States-International keyboard layout. This layout has several keys set as "dead" keys for diacritic marks - for example, pressing ^ is a dead key; it appears to do nothing until the next key is hit; if that key is one that the circumflex is an allowable diacritic, it replaces it with the marked key - that is, if I press ^ then a, I will get â - but if I press a key that it's not an allowed diacritic for, I will get the circumflex followed by the letter, e.g., ^ follows by h gives me ^h.
I wrote a AHK script that adds the diacriticalized characters for Esperanto (see below). It used to work "transparently" and matched the behavior described above. However, recently, the behavior seems to have changed: it no longer "swallows" the diacritic, and inserts a backspace before inserting the character desired.
In other words, if I type "The Esperanto character that sounds like English 'ch' is " and then type ^ then c, it replaces the space following "is" with the ĉ, and on the next keystroke, whatever it is, acts like I had hit ^ then that key.
Why? and How do I fix this?
...ANSWER
Answered 2021-Jun-03 at 22:34Don't know if I maybe missed something simple with hotstrings, but I couldn't really make it work without trying to do some even further trickery.
I figured an InputHook
(docs) implementation could work pretty well.
It might be overkill/stupid though, since it basically just creates a custom implementation for a hotstring. But well, at least it works.
QUESTION
I have a nice genlist, and I want to add checkboxes (/toggles) to all items.
I checked these pages:
- https://docs.tizen.org/application/native/guides/ui/efl/wearable/component-genlist/
- https://developer.tizen.org/ko/design/wearable/ui-components/selection-controls?langredirect=1
- https://developer.tizen.org/ko/design/wearable/ui-components/list?langredirect=1
You can provide an on/off switch, checkbox, or radio button along with the main text.
Perfect. How?
I'm aiming to be able to select items from the list, either with something like this:
Or with something like this:
I know I can use item_styles. Also know I can add my own images to swallow.end
or similar.
But is there a way to use the same designs as the OS uses? To not break UI consistency?

QUESTION
In my project I'm using Jhipster Spring Boot and I would like to start 2 instances of one microservise at the same time, but on different instances of a database (MongoDB).
In this microservice I have classes, services, rests that are used for collections A, B C,.. for which now I would like to have also history collections A_history, B_history, C_history (that are structured exactly the same like A, B, C) stored in separated instance of a database. It makes no sense to me to create "really separated" microservice since I would have to copy all logic from the first one and end up with doubled code that is very hard to maintain. So, the idea is to have 2 instances of the same microservice, one for A, B, C collections stored in "MicroserviceDB" and second for A_history, B_history, C_history collections stored in "HistoryDB".
I've tried with creating 2 profiles, but when I start from a command line History microservice, it is started ok, but if I also try to start "original" microservice at the same time, it is started but immediately history service becomes "original" microservice. Like they cannot work at the same time.
Is this concept even possible in microservice architecture? Does anyone have an idea how to make this to work, or have some other solution for my problem?
Thanks.
application.yml
...ANSWER
Answered 2021-May-20 at 09:18In general, this concept should be easily achievable with microservices and a suiting configuration. And yes, you should be able to use profiles to define different database connections so that you can have multiple instances running.
I assume you are overwriting temporary build artifacts, that's why it is not working somehow. But that is hard to diagnose from distance. You might consider using Docker containers with a suiting configuration to increase isolation in this regard.
QUESTION
I am running MassTransit 7.1.8 in Azure Functions v3 with Service Bus as transport. When the consumer throws an exception for the first time, two topics are created in my Service Bus namespace: masstransit~fault
(without any subscriptions) and masstransit~fault--mynamespace~myevent--
(with one subscription Fault-MassTransit
).
Azure Function Startup.cs
ANSWER
Answered 2021-May-21 at 14:28Azure Functions is not really using MassTransit as a transport. However, it is possible to configure certain aspects to mimic the same behavior. Setting DeliveryCount = 1
on the queue will prevent Azure from redelivering the message (which is causing the five retries, the default value is 5
).
In response to the various questions:
- That's delivery count, and MassTransit publishing the faults.
- You can configure a retry policy (as shown below)
- There is no _error queue when using Azure Functions, since MassTransit isn't the transport.
- Unless you configure a consumer for the fault, it is not consumed.
- You can change the fault topic using an entity name formatter (also shown below).
To configure bus retry for an Azure Function:
QUESTION
I have created an observable that consists of an item being transformed to another by running an async method.
...ANSWER
Answered 2021-May-13 at 13:49The question presumes a fundamental misunderstanding: According to the Observable contract, a well-behaved observable terminates after an OnError
notification. To your case, there is no, "just log and continue" option, because there's nothing to continue on. The observable that throws an exception via an OnError
is done, kaput, finito, gone forever.
A comment mentioned Retry
, which may be applicable: If you have an observable pipeline like so:
QUESTION
I'm trying to figure out how to log handled exceptions. Currently the exception thrown from an Activity will be swallowed (for example if there are DI errors when trying to create the Acitivity).
What can I do to log the caught exceptions?
...ANSWER
Answered 2021-May-11 at 12:12First, simply to correct the terminology, it isn't swallowed, it's handled.
The code above is catching the exception. If you want to log it, well, log it.
