kandi X-RAY | behaviours Summary
Behaviours is a platform to create complex programs and behaviours just connecting the simple actions that conform a program. Normally the program is based on several simple algorithms and behaviours and there is a lot of plumbing between the elements. With behaviours the plumbing is simplified to the maximum just connecting boxes, letting the programmer concentrate on high level concepts. This allows to create complex programs with just some drag and drop. Plase check the wiki for more information on how to use behaviours and how to expand it.

ANSWER
Answered 2021-Jun-11 at 18:55I'll refer to part of your question since you are raising a couple of issues:
Since Rails 6.1 form_with is non ajax by default so to make it ajax you have to pass local: false
or set the global config option (config.action_view.form_with_generates_remote_forms
) to true.
Compare form_with Rails 5.2 documentation .
:local - By default form submits are remote and unobtrusive XHRs. Disable remote submits with local: true.
With Rails 6.1
:local - By default form submits via typical HTTP requests. Enable remote and unobtrusive XHRs submits with local: false. Remote forms may be enabled by default by setting config.action_view.form_with_generates_remote_forms = true
Another thing I see is you're not doing anything with the shopzone params, but even if this will work reconsider how you built this, this is not standard use of nested attributes.

QUESTION
I'm new to Jenkins and I'm trying to figure something out.
Is there a way to add Branch Sources behavior via Groovy. This is to analyse GitHub projects in SonarQube using Jenkins.
I'm creating a multi-branch pipeline but can't seem to figure out how to add the following behaviours.
These behaviours come by default when the job is created in the UI, but don't appear when the job is created via Groovy.
I've defined this as my pipeline. Any idea how these other parameters can be added in?

QUESTION
I am developing an e-commerce project on angular where I need to implement search functionality. Now I heard about algoila and Elastic Search and we can use them as third party services for indexing the database.
Now usually what I use to do when I developed small scale applications, I use to maintain an array of combination of strings, characters, which was extracted from The actual string. Lets just give me an example, if I am storing a data for product, Where I have some fields like product name, product category, product department and etc.
So what will I do I will make a combination of strings from these three fields like, product name = "Some Product"; product category = "Some Category"; product department = "Some department"; then my result array will be [S, o, m, e, So, Som, Some, Some P, Some Pro, Some Prod, Some Produ, Some Produc, Some Product, Product, P, r, o, d, u, c, t, and so on for other fields too] and to fetch the result in client side I use to accept a string from user and query if that string exists in array of specific or set of documents. and then return the results.
...ANSWER
Answered 2021-May-15 at 07:11We use the same technique in one of our projects for the same reason as you mentioned. In the firestore
database you can use the array-contains query parameter to get the data a expected. I would recommend to add delay after typing in the search field so you don't read the data for every key stroke. Maybe also only search after 3 letters entered. That depends on your usecase. I would also use just lower or upper case and parse the searching string to it (if it fits in your use case).
As you mentioned it's only for basic search and for smaller text values but in our case it works fine and as expected.

QUESTION
I was asked to write a program in racket in order to change the behaviours of arithmetic operators from prefix to postfix. More precisely:
I want this code: (a b +)
to behave like: (+ a b)
I wanted to use define-syntax-rule
in order to change the behaviour of the + operator, but I have one problem, while using define-syntax-rule
we write at first the name of our macro, and after that we write the arguments.
My question: Is there any way to write the arguments at the beginning and the name at last in racket functions?
ANSWER
Answered 2021-May-10 at 16:33The easiest way to accomplish this is to create your own #%app
macro. Since you are essentially creating a new language here, you'll want two modules: a 'lang' module that defines your language, and a 'use' module, for the program you want to write in that language. This could be done with two files, or one file using submodules.
Here, I'll show it to you using two files:

QUESTION
HTML
...ANSWER
Answered 2021-May-06 at 21:34Every time you run Send2 it executes $("#Show1").click...
which creates a new click event handler for the show1 button. But you never remove any of the previous handlers. So when you click show1 it runs all the handlers (and thus all the Ajax requests) ever attached to the button.
That's fine the first time obviously, but after that the number of requests triggered will keep going up proportional to every execution of the Send2 function. The mess is also exacerbated by the fact that Send2 is triggered by clicking on show1!
It would make more sense to define the event handler once, outside the Send2 function. You don't need the Send2 function at all, in fact.
QUESTION
I'm trying to create a ViewController in Xamarin.iOS to show a modal page that scales height as needed, and when not enough height is available it will scroll the content.
Anyone suggestions how to set the UIScrollView to do this?
Currently I can show
- a height scaled View that is Y centered (showSmallDesign = true)
- and I can show a View that uses max height that can scroll (showSmallDesign = false)
But I can’t combine those two behaviours for some reason; creating a scroll view that expands height until parent height and enabling the scroll. I have tried a lot of different constraints but it wont work.
This is my UIController (copy paste and it should work)
...ANSWER
Answered 2021-Apr-07 at 14:20I found a solution, a modal page that stretches for all content and when max screensize has been reached it will scroll.
The trick was resetting the HeightConstraint after 'ViewDidLayoutSubviews', because the child views then measured their height. And to catch device rotations I also reset the height after 'UIDeviceOrientationDidChangeNotification'.
Here it is, free to use:
