Answered 2021-May-28 at 08:29The default column name guessed by Hibernate (based on the attribute name) is CREATED_AT
but yours is CREATEDAT
You can either rename the column in your database (recommended because it is more standard) or you can specify the column name to Hibernate like this :

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:

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.

QUESTION
I am somewhat new to coding and am trying to use the Lombok plugin to automatically create Getters/Setters e.t.c. for my fields of a specific class. In doing so I get greeted with the following error:
The error:
java: java.lang.IllegalAccessError: class lombok.javac.apt.LombokProcessor (in unnamed module @0x3b67ef9b) cannot access class com.sun.tools.javac.processing.JavacProcessingEnvironment (in module jdk.compiler) because module jdk.compiler does not export com.sun.tools.javac.processing to unnamed module @0x3b67ef9b
After doing some searching online, I found out that this error is related to an issue in OpenJDK 15 but I am currently using OpenJDK 16, hence why I am confused that I am still getting this error.
This thread claims to have a solution: https://github.com/rzwitserloot/lombok/issues/2681#issuecomment-748616687 but after implementing the plugin, it does not seem to make any difference and I still receive the error.
I have most likely made a trivial mistake since I am a beginner but if someone knows what I am missing please let me know.
Class Using @Data (Lombok): ...ANSWER
Answered 2021-Apr-07 at 07:56@FrankyFred has provided a temporary solution to be able to use Lombok: https://stackoverflow.com/a/66981165/12586904
As far as my research goes and the various responses that I received to this question, it seems like there is no possible way of running Lombok currently in OpenJDK 16. As such, an alternative to using Lombok is to put the @data
methods manually in your code. The following link briefly explains how to do this in case you are new to this topic: https://javabydeveloper.com/lombok-data-annotation/#:~:text=Lombok%20Data%20annotation%20(%20%40Data%20),as%20well%20as%20a%20constructor.

really represents:
QUESTION
ANSWER
Answered 2021-May-07 at 03:44The problem is, even though you update your state, you are not updating AsyncStorage while doing so. As per my understanding every action you perform in the cart should be updated in AsyncStorage.
It's best to write a method to update the cart as follows :
QUESTION
First time posting so apologizes if formatting is incorrect. My program has 2 lists for now. I I will be adding 4 more after solving this initial issue. One for and item the user selects, and a second with prices for the each item. I have written a code for user selection which runs.
My issue comes with the code for the program associating the item selected with the price list. My first if statement registers item_price as a float, which I gives me what I need. Item_price in the following elif statements are being seen as a list. How can I change them to a float so that the price prints instead of the list?
...ANSWER
Answered 2021-May-04 at 23:37I answered this for myself shortly after. I was using == instead of = for all of my elif statements. I feel dumb but writing this out helped me solve it.
