kandi X-RAY | fetchable Summary
Provides a mixin and decorator to add a Hash#fetch like interface to any object. You must define a [] subscript method for raw access to the fetchable data. Your [] method must return anything but nil in order for #fetch to consider a key successfully fetched. False is considered sucessful. Hash#Fetch is one of my favourite Ruby methods and can be tricky to implement its full behaviour so here it is extracted for you to add to whichever object you choose. If you're not familiar with Hash#fetch it's a great way to help eliminate nils as it raises an error when the desired key is not found. For more info consult Ruby Hash documentation.

QUESTION
I've been making Discord bots for a while, however I'm kinda stumbling upon this one element where as i want to fetch every user on the server that has the role "RoleA"
For each of the users having RoleA - I want to check if they then have any two or more of the role ids in the following array:
["232543645756","8989789789678","7567567567567","34534534534325"]
I do know you can loop the users roles to check if he has RoleID || RoleID
-- However as I want this to expandable I want to define all the roles in an Array, and then loop the user through the array to see if they have 2 or more role IDs found in the array tied to them.
Meaning if UserA has 232543645756 - but not any of the others in the array, it returns exact length === 1.
If user in this case has multiple role ids found in the array example:
232543645756 & 7567567567567 ... 345345345345 & 8989789789678 ... 345345345345 & 8989789789678 & 232543645756 etc (Multiple roles found in the array)
I want this to be fetchable by: If length >= 2 (or length > 1)
Is it possible to make a system like this? See if a user has multiple roles without having to define role1 && role2 || role1 && role3 || role1 && role4 etc - as this will be very messy if that array expands with more ids
Or is it possible to do something like If (roleArray.includes(member.roles.has...).length > 1) { Code here }
-- Or is this only possible by pushing all the users role IDs to an empty array, and then check if there is two or more matches out from the members.role.... id?

In CLI you can execute something like the following to list the names.
QUESTION
I'm trying to scrape a javascript website using scrapy and selenium. I open the javascript website using selenium and a chrome driver and I scrape all the links to different listings from the current page using scrapy and store them in a list (this has been the best way to do it so far as trying to follow links using seleniumRequest and callingback to a parse new page function has caused a lot errors). Then, I loop through the list of URLs, open them in the selenium driver and scrape the info from the pages. So far this scrapes 16 pages/ minute which is not ideal given the amount of listings on this site. I would ideally have the selenium drivers opening links in parallel like the following implementations:
How can I make Selenium run in parallel with Scrapy?

QUESTION
This is a Java 1.8 and Tomcat 9 based application, with no Spring.
I want to be able to save an object in an application scope and have it fetchable by any other session. There is only one Tomcat server, it's not federated in anyway. In this case, we have application authorization that happens based on a verified AUTH_USER and ROLE_ID header. The code runs, but every time it saves the object to the application scope, it gets forgotten or somehow not accessible to any future request. As a result, no caching happens.
My question is how do I save an object creating in one request and have it available via application scope for the next request. Please see comments in code to see where I thought it should work.
Requests come in via a web JAX-RS type function. What I have below isn't exactly how it's coded, but simplified to avoid unnecessary details. An example of one is:

The Java Servlet attributes can be used to pass data between requests. There are three different scopes: request scope, session scope and application scope.
My question is how do I save an object creating in one request and have it available via application scope for the next request. Please see comments in code to see where I thought it should work.
The Application Scope is associated with your web application. This scope lives as long as the web application is deployed. You can set the application scoped value attributes in your servlet context attribute. For example
QUESTION
Ahoy,
I have an electron app where I currently manually edit an URL in one of my files, depending on which environment (dev, prod, test) I wish to build for. However I would rather like to define that in my script so I don't have to rewrite the URL every time (e.g. electron-builder -w --x64 --ia32 --test or something like that).
As far as I can tell it is possible to have different build files (https://github.com/electron-userland/electron-builder/issues/1109), but I can't quite figure how the setup should be, and furthermore I can't figure how to get the attributes from the build files (e.g. build/publish/url). It seems possible to get icon and name (https://github.com/electron-userland/electron-builder/issues/639), but not url?
...ANSWER
Answered 2020-Feb-06 at 13:08These solutions are not very elegant, but can still help:
Prepare different configuration files beforehand
Have different configuration YAML prepared and copy them to electron-builder.yml before building, depending on your platform or flavour.
Create the build configuration dynamically
This works better for more complicated settings:
Prepare a YAML or something else that contains all configurations that are true for every platform and a mock-value (or leave it empty) for the one you want to change at build time. I use a YAML file for this, because I can copy paste this into the electron-builder.yml in case I want something new, but you know best what you need.
Before building you run a node script that:
- optionally deletes the old
electron-builder.ymlfrom the previous build if present - reads the prepared config file
- replaces the mock-value(s) with the real information in the read data
- writes the
electron-builder.ymlwith the modified data
Your npm script would then look like node prepareYml.js && electron-builder.
