QUESTION
Tried to get the returned value of the method in thymeleaf template but faced an issue. following is the environment
Controller class :
...ANSWER
Answered 2021-Apr-19 at 18:10- Start by removing
@Component
from the objects that you put in the Model (soCostDataModel
andSubList
). This annotation means that you want the Spring container to create a single instance, but this is not want you want here. - Remove
@Component
fromHighController
. You already have@Controller
which is enough to have Spring pick up the class as a singleton with component-scanning. - What is the use of
RequestToken
insideSubList
? AsSubList
is not a Spring singleton anymore, the autowiring will not work. If you really need it, maybe pass it manually via the constructor. - With
th:object="${abcdata}"
, you select theCostDataModel
instance in Thymeleaf. When you doth:field="*{abcdata}"
in the, it means that Thymeleaf will call the getAbcData() method on the selected CostDataModel, which returns the SubList instance. This is not what you want, you should use simple String field. It is a bit hard to guess what the exact solution is to your question, maybe you can use some better names than abcdata everywhere to better understand your question. In any case, you might want read about Using HTML select options with Thymeleaf on my blog to understand more about this and then maybe update your question if things are still not working.

I am trying to add small text within the H1 tags at the same time adding an icon before the text, but unfortunately it is not working, I have two issue in the same h1 tag in the header class noting that I am building my site using bootstrap framework :

Answered 2021-Jan-22 at 10:41I checked your codes. It seems like there is a problem on bootstrap version you're using. I removed both of your bootstrap links and added one. I also added Mansi's comment to make the icon be resizeable. You can check from below snippet
QUESTION
I have used as many examples online as I could cobble together in an attempt to get my two simple models to have the ability to do an inline formset allowing me to add many files to a technial drawing. This is not working, I can only add one file for the Create and the update only updates the Technical_Entry model, not a file...which in of itself acts funny. The UI ona create shows one spot to add a file, then save the entire record and its child record. That works. The update, the UI shows the file that was saved earlier..(great!) but then has two more 'choose file' slots (random?) and adding a file to those does nothing when the save is clicked. It doesn't remove the file previously added in the create, but it also does not save the new file added to the now three slots (one used, two free). So update does not work for the files for some reason.

The default vuetify themes have a very limited amount of properties to tweak.
...ANSWER
Answered 2020-Dec-01 at 22:33Well everything is almost right except one thing.
You need to have sass-loader
version 8.x to make it work with customVariables:
part. Install it with npm install -D sass-loader@8
This because of sass-loader
takes additional data different way in different versions. more information about sass-loader
After that, you should be able to override framework variables thru editing vuetify.scss
file.

...ANSWER
Answered 2020-Sep-09 at 20:57You are running the script in head
and expecting all of the document's content to be loaded (for example the typed
div). This explains why it works in Codepen but not in your local environment, because Codepen runs the javascript after the html content has been loaded.
To solve this, you can use an event listener to wait for the document to fully load.
The document is not loaded by the time you are trying to find an element with the id typed
