| DataSetExtensions referenced by Project and using System.Data but extension methods not available Posted: 03 Aug 2021 08:42 AM PDT I am trying to run this code in this answer https://stackoverflow.com/a/1430489/2102329 whose call to ToList() relies on the extension methods in the referenced assembly System.Data.DataSetExtensions.dll. DataTable dtUserAccounts = sp.getDataTable(); List<UserAccount> listOfUserAccounts; dtUserAccounts.AsEnumerable().Select(m => new UserAccount() { UserId = m.Field<string>("UserId"), FirstName = m.Field<string>("FirstName"), LastName = m.Field<string>("LastName") }). //<-- ToList() is not available
I have reviewed similar cases on StackOverflow but cannot get this to work. I am using Visual Studio 2017 but the original project will have been created in an earlier version. The code is in a public method of a public class in the project's default namespace. I have the correct using statement for System.Data already. The project targets .NET 4.7.1. The extension methods are not available. In References there are both System.Data and System.Data.DataSetExtensions (I have removed and added these back in to be sure). I have tried cleaning the solution and rebuilding. I have even created an additional project in the same VS 2017 solution targeting the same .NET version and this actually works so this is my fudge of a workaround but I must be missing something here.  |

| Why do I receive a security origin error when downloading a file from Firebase storage with CORS enabled? Posted: 03 Aug 2021 08:41 AM PDT I have a website linked to firebase storage. I want the user to be able to download a file (stored in firebase storage) on his computer when clicking on a download button. The issue -> I receive this error message in the console "The download attribute on anchor was ignored because its href URL has a different security origin." CORS is set up through gsutil command following this configuration -> https://firebase.google.com/docs/storage/web/download-files [ { "origin": ["*"], "method": ["GET"], "maxAgeSeconds": 3600 } ]
My function to download the file : function forceFileDownload(url) { // This can be downloaded directly: var xhr = new XMLHttpRequest(); xhr.responseType = 'blob'; xhr.onload = (event) => { var blob = xhr.response; }; xhr.open('GET', url); xhr.send(); }
Which is called here : targetDoc.get().then((doc) => { imgRef.getDownloadURL().then(function(url){ let li = document.createElement("li"); let a = document.createElement('a'); a.appendChild(document.createTextNode("Download")); a.setAttribute('id', url); a.setAttribute("onclick","forceFileDownload(this.id)"); li.appendChild(a); }); })
When I click on the download button the image appears in another tab. I think the issue might come from my function and not from the CORS configuration (I've tried dozen of CORS configurations with the same result). At some point it was working in Chrome but not anymore (I don't know how), and it never worked in Safari. Thanks for your help. [My post has been associated with similar questions, however it didn't resolve my issue so I am posting it again.]  |
| Problem with lstrip and backslash in python Posted: 03 Aug 2021 08:41 AM PDT I know there is already many ressources about the problem of backslash in python, I read many of these but none help me. I'm working on large data set with Pandas. I'm creating a loop to iterate over multiple csv files in a windows folder. Then it proceed to several data manipulation. Then I want to save each different input csv in different output csv. In itself, it works, but I want to have clean name after the export/save. And i'm not able to do this. Complete name are "C:\blabla blabla\data number1\Id 1\Csv\01 - Decembre\12-xx-14_processed_1.csv" xx = multiple day of the month Here's the code : for files in folder : df = pd.read_csv(files, sep=';', low_memory=False, index_col=None) file_name = str(files) file_name = file_name.lstrip(r'C:\blabla blabla\data number1\Id 1\Csv\01 - Decembre\\') file_name = file_name.rstrip('_processed_1.csv')
I want to have only "12-xx-14.csv" in the end So I did the following : df.to_csv(r'C:\blabla blabla\data number1\Reprocessed CSV\December'+str(file_name)+'.csv',index=False)
Saving it in another folder for the project management. I should have "12-xx-14.csv" as an output.. but I have "2-xx-14.csv" ! My first "1" is going into the bin and I really don't know why ?? I guess it's related to the backslash character.. But if i'm deleting the last two backslash, the name become "01 - December\12-xx-14". I can't even manage to suppress "01 - Decembe" without the last "r", it won't work. I'm currently upgrading to python 3.9 to test suffix/prefix, but in the mean time i'm stuck with this. Thank you !  |

| Caching or retrying + switching between API calls if one is down Posted: 03 Aug 2021 08:40 AM PDT I am attempting to scope a problem where I have two identical external services that can be called from a user GET request to an API. Lately, I have noticed that the primary external service that I would rather hit has been going down randomly. So, I would like to develop this API to try and call the first service and if it's down call the other external service. If this first service is down, any subsequent requests would go to the second external service and the first service would only be retried after a certain period of time. Here's a psuedocode example of what I'm trying to accomplish: user GET request to api: try to call external_api1: if external_api1 is up: return external_api1 response else: try to call external_api2: if external_api2 is up: return external_api2 response else: return error to user subsequent user requests go to external_api2 external_api1 is retried after a certain amount of time
I am unsure of the appropriate strategy to handle the last two lines in particular, where requests are routed to the second service and the first service is retried after a certain amount of time. I wonder if this is a background service checking to see if the first service is up continuously or if there is a caching strategy here. I would appreciate any advice on a possible path forward.  |
| How to use asyncio.wait_for to run_until_complete to synchronously call async method in Python Posted: 03 Aug 2021 08:40 AM PDT To allow timeouts receiving data via Python websocket, the FAQ: How do I set a timeout on recv()? recommends using asynchronously receive data: await asyncio.wait_for(websocket.recv(), timeout=10)
Since the function I receive data is not async, I've adapted this answer to run the asyncio loop until data was received or the timeout occurred: loop.run_until_complete(asyncio.wait_for(ws.recv(), timeout=10))
Unfortunately this statement seems to be not valid, since the following exception occurs: An asyncio.Future, a coroutine or an awaitable is required For me, it looks like asyncio.wait_for is no valid parameter for the run_until_complete although the documentation clearly shows an example which awaits for it. What am I missing here - and what would be the correct way to use asyncio.wait_for in a synchronous method?  |

But for some reason I enter in a infinite loop where the controller keep doing the verification of email and CPF over and over again.  |
| Replacing value in list based on input and dictionary ;-; Posted: 03 Aug 2021 08:41 AM PDT I need to print out a 4x4 table that's labeled ( A B C D ) horizontally and 1234 vertically and ask the user to place a randomly generated number in the table (eg. A1, B2) num = randomly generated number table = [ [' ', ' ', ' ', ' '],\ [' ', ' ', ' ', ' '],\ [' ', ' ', ' ', ' '],\ [' ', ' ', ' ', ' ']] ans = input('where would you like to place it?')
I used a dictionary to assign A1 : table[0][0] and so on Tried to replace the value with: if ans in dictionary: table.replace(dictionary.get(ans),num)
It's not working for me but I only understand how to do it this way.  |
| How can I implement vertical scroll snapping with `IntersectionObserver`? Posted: 03 Aug 2021 08:41 AM PDT I am inspired by Rolls Royce website and want to implement the same scroll snapping feature in mine as well, I did it with the HTML default scroll-snap-type which gives me expected behavior but creates two scrollbars, one for the container and another one for the body, which is not expected so I tried to go with the IntersectionObserver but it causes an issue, I can travel to only adjacent slide when directly jumping from 1st slide to 3rd slide. Here is the code sandbox link: https://codesandbox.io/s/scrollsnap-forked-pre0c?file=/pages/index.vue Here is the code that I am working <template> <main class="landing"> <nav class="scroller"> <ul class="scroller__list"> <li class="scroller__item" v-for="(slide, index) in slides" :key="index" @click.prevent="scroll(slide.id)" > <a class="scroller__dot" :href="'#' + slide.id" @click.prevent="scroll(slide.id)" ></a> </li> </ul> </nav> <div class="slides-container"> <slide class="slide" v-for="(slide, index) in slides" :key="index" :img="slide.img" :id="slide.id" :format="slide.format" :filter="slide.filter" >{{ slide.content }}</slide > </div> </main> </template> <script lang="ts"> import Vue from "vue"; export default Vue.extend({ data() { return { slides: [ { img: "car-slide-1.png", content: "hello world", id: "car-slide-1", filter: "color-burn", }, { img: "car-slide-2.png", // promo-video.mp4 content: "Second Car", id: "car-slide-2", filter: "color-burn", // format: "video", }, { img: "car-slide-3.png", content: "Third slide", id: "car-slide-3", filter: "color-burn", }, ], observer: null as any as IntersectionObserver, options: { threshold: [0.5], root: process.browser ? document.getElementsByClassName("slides-container")[0] : null, } as IntersectionObserverInit, }; }, methods: { scroll(id: string, who: string | null = null) { console.log("scrolling to ", id, who ? "by " + who : ""); document.getElementById(id)?.scrollIntoView({ behavior: "smooth", block: "start", }); }, }, mounted() { let scrolling = false; this.observer = new IntersectionObserver((entries, observer) => { entries.forEach((entry) => { if (entry.isIntersecting && !scrolling) { let top = entry.boundingClientRect.top; scrolling = true; window.scroll({ behavior: "smooth", top: window.pageYOffset + top }); } scrolling = false; }); }, this.options); document .querySelectorAll(".slide") .forEach((slide) => this.observer.observe(slide)); }, }); </script>

| How to make props stateful/ how to get updated props from root config to child apps in single spa react? Posted: 03 Aug 2021 08:41 AM PDT I have a single spa application where I am using 3 child apps (each being a micro-frontend). For 1 child app, I am mounting onto the root html and setting in always active status. For the rest 2, basing on the routes, will mount/un-mount themselves onto the root html. For the child that is always active, I am passing the current path as prop from the root so that basing on the path, components within that child should render (conditional rendering). The issue I am facing is, child is able to receive the prop from the root but when the path changes, the new path is not getting reflected into the child and I have to reload the page manually in-order to conditional render those components within that child app. So, here are the root-config.js files and child.js files. **root-config.js** import { registerApplication, start } from "single-spa"; registerApplication({ name: "@mrc/app1", app: () => System.import("@mrc/app1"), activeWhen: ["/app1", (location) => location.pathname.startsWith("/app1")], }); registerApplication({ name: "@mrc/app2", app: () => System.import("@mrc/app2"), activeWhen: ["/app2", (location) => location.pathname.startsWith("/app2")], }); registerApplication({ name: "@mrc/app3", app: () => System.import("@mrc/app3"), activeWhen: ["/"], customProps: { currentPath: window.location.pathname, }, }); start();
**app3.js** import React from "react"; import Header from "./components/Header/Header"; import LeftPane from "./components/LeftPane/LeftPane"; import NavBody from "./components/NavBody/NavBody"; const App = ({ currentPath }) => { return ( <> <Header /> {typeof window !== "undefined" && currentpath !== "/" ? ( <LeftPane /> ) : null} {typeof window !== "undefined" && currentPath === "/" ? ( <NavBody /> ) : null} </> ); }; export default App;
The goal is LeftPane component from app3 should not be rendered only for path="/" and NavBody should be rendered only for path="/". How can I achieve this?  |

| Timber: archive-post_type.php not firing; equivalent in non-Timber themes works Posted: 03 Aug 2021 08:41 AM PDT Using Timber, I'm trying to render a custom archive page for my custom post type. CPT is person, and I'm simply trying to render archive-person.php when visiting "mysite.com/person". No matter what I do, all I get is the output of archive.php, never archive-person.php. Yes, I have been hitting 'Save' on permalinks as many people suggest. As a test, using WP's 2020 base theme, I made an equivalent archive-post_type.php in the classic WordPress way, and everything works fine. This is indicating my cpt's and permalinks are ok, and the issue perhaps has to do with my Timber-based theme specifically. I've tried changing my CPT name properties to make sure I'm not creating permalink conflicts. Timber views/partials, pages, singles and single-post_type.php are all rendering fine. Other than tinkering with archive*.php pages, what's the first thing I should be looking at? Within functions.php Timber initialization, anything major that would specifically affect archives only? UPDATE: In writing this post I see what could be an issue. Do I have to register my CPTs and taxonomies explicitly through Timber init, for it to be fully aware of them? archive.php (very similar to one from Timber starter theme) <?php use Timber\Timber; global $paged; if ( ! isset( $paged ) || ! $paged ) { $paged = 1; } $templates = array( 'pages/archive.twig', 'pages/index.twig' ); $context = Timber::context(); $context['title'] = 'Archive'; if ( is_day() ) { $context['title'] = 'Archive: ' . get_the_date( 'D M Y' ); } elseif ( is_month() ) { $context['title'] = 'Archive: ' . get_the_date( 'M Y' ); } elseif ( is_year() ) { $context['title'] = 'Archive: ' . get_the_date( 'Y' ); } elseif ( is_tag() ) { $context['title'] = single_tag_title( '', false ); } elseif ( is_category() ) { $context['title'] = single_cat_title( '', false ); array_unshift( $templates, 'archive-' . get_query_var( 'cat' ) . '.twig' ); } elseif ( is_post_type_archive() ) { $context['title'] = post_type_archive_title( '', false ); array_unshift( $templates, 'archive-' . get_post_type() . '.twig' ); } // Grabs everything on the site, regular posts and CPT's. $context['posts'] = new \Timber\PostQuery(); // Just for testing, to check if "person" posts can at least be rendered via archive.php. They do. //$args = ['post_type' => 'person']; //$context['posts'] = new \Timber\PostQuery($args); Timber::render( $templates, $context ); ?>
archive-person.php Just a pared-down version of archive.php, with 'person' forced as post_type (as opposed to grabbing all posts): use Timber\Timber; global $paged; if ( ! isset( $paged ) || ! $paged ) { $paged = 1; } $templates = array( 'pages/archive-person.twig' ); $context = Timber::context(); $context['title'] = 'Archive: Person'; $args = [ 'posts_per_page' => 10, 'paged' => $paged, 'post_type' => 'person', ]; $context['posts'] = new \Timber\PostQuery($args); Timber::render( $templates, $context );
functions.php class mySite extends Timber\Site { public function __construct() { add_theme_support( 'post-thumbnails' ); add_theme_support( 'menus' ); add_filter( 'timber_context', array( $this, 'add_to_context' ) ); parent::__construct(); } function add_to_context( $context ) { $context['menu'] = new \Timber\Menu('main-menu'); $context['site'] = $this; return $context; } } new mySite(); function create_posttypes() { register_post_type( 'person', array( 'labels' => array( 'name' => __( 'Persons' ), 'singular_name' => __( 'Person' ) ), 'public' => true, 'has_archive' => true, 'show_in_rest' => true, 'supports' => array( 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'trackbacks', 'custom-fields', 'comments', 'revisions', 'page-attributes' ) ) ); } add_action( 'init', 'create_posttypes' );
