QUESTION
I am trying to test a component. It uses 2 different reducer states with Ngrx. How can I tell in the initialState of the test which one comes from AppState and the other comes from AdminState (LazyLoaded) please?
...ANSWER
Answered 2021-Apr-30 at 18:49It's most likely your initialState
is wrong.
Download the Redux dev tools (https://chrome.google.com/webstore/detail/redux-devtools/lmhkpmbekcpmknklioeibfkpmmfibljd?hl=en, there is also a Firefox one) and see the structure of your store using that tool. This is how you configure it (https://ngrx.io/guide/store-devtools) and then you can do npm start and should see the structure of your store.
I bet your initialState should be something like this:

QUESTION
I'm using OpenSUSE Leap 15.2
operating system together with pre-installed R v3.5.0
. I did not have to install any package except rstudio
.
Here are installation details:
...ANSWER
Answered 2021-May-29 at 13:41In my experience, these errors on Unix often stem from missing external libraries. For example, installing the R xml2
package requires libxml2-dev
to be installed via the system package manager (i.e. outside R) otherwise installation will fail.
I can't read French, but it looks to me as though the dependency jpeg
failed, due to a missing external jpeg library, and then everything cascaded from there. You could try installing some version of the libjpeg
library. I know it comes pre-installed in Ubuntu which may be why that worked for you. I'm a little surprised it doesn't come installed already in OpenSUSE, but I have no experience with OpenSUSE.
QUESTION
I am new to Go, and learning Interfaces and Structs. I am having 2 structs - ServiceSection and SliderSection and I am trying to accomplish the below 2 tasks with each of them-
- GET the JSON response and unmarshal it.
- Use the struct to create HTML using "html/template"
Therefore, I am trying to create a common function to perform both the tasks that can work for multiple Structs. The plan is to create 5-6 more such structs. Below is the code I have created-
...ANSWER
Answered 2021-Jun-01 at 12:22A couple of things:
- A Go interface is an abstraction - so it's rare, if ever, that you need to get the address of an interface
- if a struct's method needs to change the state of the struct (and persist the change), use a pointer receiver.
So to fix your immediate problems:
QUESTION
I am testing an application written in React.js for responsiveness on mobile devices. Hence my request to you, to test the application from this angle and share your thoughts on what can be improved. Certainly I want to improve the performance of the application, so that it loads faster. Is it enough to reduce the weight of photos and add lazyloading atribute to some photos?
...ANSWER
Answered 2021-May-30 at 16:12THIS IS TESTED ON A SMALL WINDOW SIMULATING MOBILE CLIENTS
Two problems here on this part. First, the text in the button is not properly displayed, and secondly, not sure if it is done on purpose, but the design of overlapping white text on a light background makes it a bit hard for people to see.
Over here, the line is sitting on top of the button on smaller screens and it is hovering over some of the content. Say you are clicking that button in the center, it doesn't work because there is this line on top of it, and that might not be something you want:
And here, your image is overflowing on the x axis:
Finally, this navigation bar on mobile devices is positioned absolutely on top of the screen, and I'm not sure if that's what you were planning to do, I recommend sticking it on to the screen such that even when the user scrolls, it's still there, fully exposed and what this does is that, the user doesn't have to scroll all the way to the top to find that navigation bar.
But, overall, this looks quite good and the color scheme really suites the theme.

I've recently implemented a lazy image loading feature on an image-heavy website, and have been having issues with reflow. I fixed the problem by manually specifying the image dimensions using the width

QUESTION
I am trying to do a sample User CRUD page with Primefaces+JSF+Spring Boot. On the page, I have a LazyLoading enabled table. My User object has no 1-to-N or N-to-1 fields, all are primitive fields that does not need database access or initialization upon reaching. (So FetchType.EAGER won't help)
When trying to show a User from the UserList table on a pop-up, getting the exception below:
...ANSWER
Answered 2021-May-22 at 16:53It seems that LazyLoading was a red herring on this question. The issue is with how the dialogs are invoked. The jsf snippet includes line selection on the dataTable, but the dialogs are invoked by buttons. The two can be out of sync. Instead, set the current row selection when the dialog is invoked, as follows:

I have written the following HTML code :
My main focus is to align the list items - HOME | All About Kittens | Feeding Your Kitten
properly. It's currently appearing as a simple list. I want to make it like :
Here the list items are Home, Shop and collections and they are aligned horizontally
Plus when you hover over an item it changes in color and a line appears below it
Any ideas how should I go about implementing this way
ANSWER
Answered 2021-May-22 at 12:15You can use display: flex;
to show navigation like the UI you mentioned.

I have some issues where I don't really know where the problem in the code is. I've searched a bit on it but no luck.
I've been trying to make a contact form using Angular Reactive Forms and with HttpClient to make the post requests and such. Has anyone got any input in regards to this? Problem is located at the FormData.append part. Error message I get is "Object is possibly 'null'." for the three formData.appends I use.
Component:
...ANSWER
Answered 2021-May-20 at 05:30I fixed it with a little help elsewhere. Seems I firstly forgot to import Reactive Forms, as I only had Forms imported.
Then I had some issues in regards to formData.append
. I found a better solution to the coding I had done in that part and it works good. I also had some issue where I could not use response["result"]
. But also found the solution for that with (response: any) =>
I don't know if I had typed something wrong on the form part, but it works now after copying something from StackBlitz.
