| Table content showing only when i comment a line that is not executing/ Vue 3 Posted: 15 Oct 2021 09:38 AM PDT I have a table that only shows its content if i remove a line of code inside a method. I'm trying to remove a table row, but even if the code that removes the row is not executed, the table won't show its content until i remove that line or if the component gets hot-reloaded. Here is my html template: <table class="table table-dark table-hover"> <thead> <tr> <th v-for="header in headers" :key="header"> {{ header }} </th> <th>Acciones</th> </tr> </thead> <tbody> <tr v-for="(data, index) in tableContent" :key="data.id"> <td v-for="value in data" :key="value"> {{ value }} </td> <td> <div class="action-buttons"> <button class="btn btn-warning">Editar</button> <button class="btn btn-primary" @click="deleteRow(data.id, index)" > Eliminar </button> </div> </td> </tr> </tbody> </table>
And my js code: import { ref } from "vue"; export default { name: "DataTable", props: { headers: Array, content: Array, apiUrl: String, }, setup(props) { const tableContent = ref(props.content); const deleteRow = async (id, rowIdx) => { try { console.log(props.apiUrl, id, rowIdx); tableContent.value.splice(tableContent.value.indexOf(id), 1); /*<------ this is the line*/ } catch (error) { console.error(error); } }; return { tableContent, deleteRow, }; }, };
If that js line is commented or deleted, the table shows its content as normally it does, but if the line is uncommented it just won't show the content. If i hot-reload the component with the line uncommented, the table will show its content but If i reload the page, the table content won't get rendered  |
| How to do a join bewteen tables with a conditional statement Posted: 15 Oct 2021 09:38 AM PDT I have two tables. I do not have a direct field to join. But, what I want to do, is to take everything in Table1, and join it with a field that is "in" a field in Table2. I know this will result in multiple connections between rows in Table2 to Table1, but that is okay. Let me give a for instance.. Please have some patience. I know there is a way to make a query to do this, but I have not done that before. But, I can give sample data, and what I want to do with it. Table1(SN, Customer) Table2(SNRange, OrderNum, Line Item) Table1[12, Bob, 13, Bob, 14, Bob, 54, Bill, 55, Bruno, 56, Bruno, 100, Sylvia] Table2[12,13, WO234, 1, 14, WO234, 2, 54, WO300, 1, 55,56, WO532, 1] Result:(SN, Customer, WONum, LineNum) [12, Bob, WO234, 1, 13, Bob, WO234, 1, 14, Bob, WO234, 2, 54, Bill, WO300, 1, 55, Bruno, WO532, 1, 56, Bruno, WO532, 2, 100, Sylvia, NULL, NULL] My very uneducated guess would be: '''SELECT * From Table1 INNER JOIN SN ON Table1.SN in Table2.SNRange''' I think this defines the situation, and loose logic on how to do it. I need some format help. SNRange is a string with commas separating the numbers. I know my formatting is horrible, but I'm not very deep in SQL, but I have needed to do some complex things. Thank you!! Rod  |

| Using product flavors with multiple firebase apps Posted: 15 Oct 2021 09:37 AM PDT I have a development and a production firebase console, each with an android app. I am trying to connect my development environment to the development google-services.json and the production one to the other google-services.json. I placed the respective google-servies.json files in app/src/dev/ and app/src/prod/ To my understanding, app/build.gradle requires android { ... flavorDimensions "default" productFlavors { dev { applicationIdSuffix '.dev' resValue "string", "build_config_package", "com.myapp" } prod { resValue "string", "build_config_package", "com.myapp" } } ... }
The development firebase's appId is com.myapp.dev and the production one is just com.myapp When I run react-native run-android --variant=prodDebug everything works fine, but if I run react-native run-android --variant=devDebug it still connects to the production firebase. How can I get them to reliably switch between consoles based on my variant?  |
| Testing Component That Fetches Data With React Testing Library Posted: 15 Oct 2021 09:37 AM PDT I have a component that does some very basic fetching of data. Once this data is fetched, users can interact and click on the items in a list. When an item is clicked, it is displayed at the top of the component with a description as the "active item". I'd like to test the click functionality by making sure that an item can be set to active, and also removed from being active. However, I am not sure how to do this, since it relies on data from an API. Any ideas? Component Code interface Item { title: string; description: string; } const Home: NextPage = () => { const [items, setItems] = useState<Item[]>([]); const [activeItem, setActiveItem] = useState<Item | null>(null); const fetchItems = async () => { try { const res = await axios.get<Item[]>('http://localhost:3090/api/items'); setItems(res.data); } catch (error) { console.log(error); } }; const handleActiveItem = (item: Item) => { if (activeItem?.title === item.title) { setActiveItem(null); } else { setActiveItem(item); } }; useEffect(() => { fetchItems(); }, []); return ( <div> {activeItem && ( <div data-testid="active-item"> <h1>{activeItem.title}</h1> <p>{activeItem.description}</p> </div> )} <ul> {items.map((item: Item) => ( <li key={item.title} onClick={() => handleActiveItem(item)}> {item.title} </li> ))} </ul> </div> ); };
Test Code describe('Home', () => { it('matches snapshot', () => { const tree = renderer.create(<Home />).toJSON(); expect(tree).toMatchSnapshot(); }); render(<Home />); it('Initially there is no active item', () => { const activeItem = screen.queryByTestId('active-item'); expect(activeItem).not.toBeInTheDocument(); }); it('When an item is clicked in the list, it becomes the active item', () => { // }); it('If there is an active item and it is clicked in the list, active item is emptied', () => { // }); });

| Reshaping a coordinate list Posted: 15 Oct 2021 09:37 AM PDT I have 3xN dimensional array containing coordinates ([x1,x2,...xN],[y1,y2,...yN],[z1,z2,...zN]), I need to reshape it into a Nx3 dimensional array of coordinates ([x1,y1,z1],[x2,y2,z2],...,[xN,yN,zN]).

| Bulk insert data into empty (but existing) records with SQL Posted: 15 Oct 2021 09:37 AM PDT The first table columns (A to G) are already filled with data for each row/record, but the columns H to K have no data in it yet.

| Use native CSS min/max functions with LESS Posted: 15 Oct 2021 09:38 AM PDT I want to use the min() CSS function with a stylesheet written in LESS. However, LESS has its own min and max functions that precompute values (making it impossible to mix-and-match units). How do I get it so the output CSS has the min/max functions as I wrote them? Here is the style in the LESS file, which should also be the expected output. canvas { background: white; width: min(95vh, 95vw); height: min(95vh, 95vw); }
I am using lessc 3.13.1, which produces the following error: ArgumentError: error evaluating function `min`: incompatible types in <snipped> on line 49, column 12: 48 background: white; 49 width: min(95vh, 95vw); 50 height: min(95vh, 95vw);

| Xcode 13 doesn't show quick help when option click defined property on left Posted: 15 Oct 2021 09:37 AM PDT A quick question. I use to see the inferred type by option click the property or object on the left of a statement. After upgrade to Xcode 13, for instance, when I option click on below text property, there is no quick help popping up. Do u guys meet this same issue? Just Google it, no clue found. let text = "Have a nice day"
Quick help is only shown when I option-click on an iOS built-in property, function, etc. It doesn't appear for custom defined things. For code below, when I optional click on viewDidLoad or addSubview , I could get quick help menu popped up. But without luck for tableView, which is a user defined stuff. private lazy var tableView: UITableView = { let table = UITableView() table.register(UITableViewCell.self, forCellReuseIdentifier: "cell") return table }() override func viewDidLoad() { super.viewDidLoad() view.addSubview(tableView) tableView.frame = view.bounds }

| Python Crash Course 2nd Edition exercise 12-4 Posted: 15 Oct 2021 09:38 AM PDT Have 3 files. rocket_game.py, rocket.py, settings.py. Contents of rocket.py. Key "Up" arrow does nothing. Key "Down" arrow moves the ship up. If I change the last line to "self.y += self.settings.ship_speed", down arrow moves the ship down. But why won't the game hook the up arrow? def update(self): """Update the ship's position based on the moving flag.""" if self.moving_right and self.rect.right < self.screen_rect.right: self.x += self.settings.ship_speed elif self.moving_left and self.rect.left > 0: self.x -= self.settings.ship_speed if self.moving_up and self.rect.top < self.screen_rect.top: self.y += self.settings.ship_speed elif self.moving_down and self.rect.bottom > 0: self.y -= self.settings.ship_speed
Key "Up" arrow does nothing. Key "Down" arrow moves the ship up. If I change self.y += self.settings.ship_speed, down arrow moves the ship up, I understand I why. But why doesn't the up arrow? If I print the events, it sees me pressing the up arrow, but the rocket does not move. The OTHER issue, the top and bottom boundaries don't seem to exist. The bottom left corner of the screen is described as being coordinates 0, 0 respectively. I did try setting the bottom boundary as 0, but the ship still flies below the screen. Left and right boundaries work fine. New to python programming, and I tried reading pygame API for rect but it doesn't seem to have the reference that I need. It does list top and bottom rather than up and down. I have tried multiple ways in both the rocket_game.py and rocket.py. No error messages, and the ultimate goal was to add the ability to move up and down, move left and right, while within the screen_rect borders.  |

| AngularJS Form validation transition to valid when some elements are not even touched yet Posted: 15 Oct 2021 09:38 AM PDT 
I have a save button that is only enabled when all form data is provided and the form is valid. I don't understand why bandwidth options are not selected and the form become valid. myForm.$valid transition to true ... it should stay as false <button id="save-create-account-modal" type="submit" class="btn btn-success" ng-disabled="!myForm.$valid || $ctrl.disableButton" ng-click="$ctrl.accessPointSave($ctrl.accessPoint)"> Save </button>
Bandwidth select menu <div class="col-xs-3"> <div class="form-group" ng-class="{ 'has-error': myForm.uplink.$touched && myForm.uplink.$invalid }"> <label for="uplink" class="required"> <translate>GENERAL.UPLINK.value</translate> </label> <select id="edit-service-plan-uplink-select" class="form-control" name="uplink" ng-model="$ctrl.accessPoint.uplink" ng-options="bandwidth.value as bandwidth.option for bandwidth in $ctrl.uplinks" required> </select> </div> <span class="message error" ng-messages="myForm.uplink.$error" ng-if="myForm.uplink.$touched"> <p ng-message="required"> <translate>GENERAL.FORM_VALIDATIONS.REQUIRED_FIELD.value</translate> </p> </span> </div> <div class="col-xs-3"> <div class="form-group" ng-class="{ 'has-error': myForm.downlink.$touched && myForm.downlink.$invalid }"> <label for="downlink" class="required"> <translate>GENERAL.DOWNLINK.value</translate> </label> <select id="edit-service-plan-downlink-select" class="form-control" name="downlink" ng-model="$ctrl.accessPoint.downlink" ng-options="bandwidth.value as bandwidth.option for bandwidth in $ctrl.downlinks" required> </select> </div> <span class="message error" ng-messages="myForm.downlink.$error" ng-if="myForm.downlink.$touched"> <p ng-message="required"> <translate>GENERAL.FORM_VALIDATIONS.REQUIRED_FIELD.value</translate> </p> </span> </div>
How can debug this further?
Updated I also tried to add required in the same line as my <select> tags still not working as expected  |
| Getting empty response from gRPC call Posted: 15 Oct 2021 09:37 AM PDT I have a simple gRPC server and client. The server and client are working fine (I assume since I am getting a response and no error). However the response is empty which I have no idea why. Here is the proto message.proto syntax = "proto3"; message Msg { int32 timeStamp = 1; string text = 2; string sender = 3; } message Empty {} service MsgService{ rpc AllMessages (Empty) returns (MsgList) {} } message MsgList { repeated Msg msgs = 1; }
and server.js const grpc = require('@grpc/grpc-js'); const PROTO_PATH = "./message.proto"; const protoLoader = require('@grpc/proto-loader'); const options = { keepCase: true, longs: String, enums: String, defaults: true, oneofs: true } const packageDefinition = protoLoader.loadSync(PROTO_PATH, options); const msgProto = grpc.loadPackageDefinition(packageDefinition); const server = new grpc.Server(); let savedMessages = [ { timeStamp: 1, text: "lorem", sender: "alex" }, { timeStamp: 2, text: "ipsum", sender: "bob" }, { timeStamp: 3, text: "dolor", sender: "alex" }, { timeStamp: 4, text: "net", sender: "bob" } ]; server.addService(msgProto.MsgService.service, { AllMessages: (_, callback) => { callback(null, savedMessages); } }) server.bindAsync("127.0.0.1:50051", grpc.ServerCredentials.createInsecure(), (err, port) => { if (err) { console.log(err); } console.log(port); server.start(); console.log("Server running at 127.0.0.1:50051"); })

| Correct way to trigger radio button handler with jQuery Posted: 15 Oct 2021 09:37 AM PDT I have two radio buttons. Depending on which one is checked, I want to show or hide a <div> on the page. So I created this handler. $(function () { $('input[name="Search.LatestOnly"]').on('change', function () { if ($(this).val() == 'true') $('#date-section').hide(400); else $('#date-section').show(400); }); });
This works fine. But I want to set the <div> visibility to the correct state when the page loads, so I added this line: $('input[name="Search.LatestOnly"]:checked').trigger();
This produces run-time errors that aren't meaningful to me. jQuery.Deferred exception: Cannot convert undefined or null to object TypeError: Cannot convert undefined or null to object at hasOwnProperty () at Object.trigger (https://localhost:44377/lib/jquery/dist/jquery.min.js:2:70619) at HTMLInputElement.

| What's the best way to get top nth values from Dictionary? Posted: 15 Oct 2021 09:37 AM PDT I am trying to get the top n values from a dictionary. The part that is making it not easy for me is that if there are multiple values of the same rank, I need to keep all of them. For example, if a dictionary looks like: Dictionary<string, int> dict = new Dictionary<string, int>(); dict.Add("AAA", 91); dict.Add("BBB", 97); dict.Add("CCC", 98); dict.Add("DDD", 92); dict.Add("EEE", 97); dict.Add("FFF", 100);
and if I want Top 3, I need to get dict.Add("BBB", 97); dict.Add("CCC", 98); dict.Add("EEE", 97); dict.Add("FFF", 100);
because BBB and EEE have the same rank. I first sorted the dictionary by the rank, and tried Take() but it only took one of the two. /* Does not work */ var dictSorted = dict.OrderByDescending(x => x.Value).ToDictionary(x => x.Key, x => x.Value).Take(3); /* The below only prints FFF = 100 CCC = 98 BBB = 97 but not EEE = 97 */ foreach(KeyValuePair kvp in dictSorted){ Console.WriteLine(kvp.Key + " = " + kvp.Value); }
Is there a good way to achieve this?  |
| SQLAlchemy - Eager load subquery as column for an ORM class Posted: 15 Oct 2021 09:37 AM PDT I have two tables. One is mapped as an ORM class like so: from typing import Union from dataclasses import dataclass from api.models import db, SerializerMixin @dataclass class Company(db.Model, SerializerMixin): __tablename__ = "Company" company_id: int = db.Column(db.Integer, primary_key = True) name: str = db.Column(db.String(50), nullable = False, unique = True) primary_contact: Union[int, None] = db.Column(db.Integer, db.ForeignKey("User.user_id")) website: Union[str, None] = db.Column(db.Text)
The second one is written as just a plain SQL table (wrote it this way since I don't plan to query from this table directly, only used for JOINS and COUNTS): user_company_table = db.Table("UserCompany", db.Column("user_id", db.Integer, db.ForeignKey("User.user_id"), primary_key = True, unique = True), db.Column("company_id", db.Integer, db.ForeignKey("Company.company_id"), primary_key = True), db.Column("assigned", db.DateTime, server_default = text("CURRENT_TIMESTAMP"), onupdate = datetime.utcnow), db.Column("approved", db.Boolean, nullable = False, default = False) )
I need to fetch all columns from Company while at the same time getting a COUNT of all users who have approved = true and are assigned to one specific company. The resulting SQL would look like this: SELECT Company.company_id, Company.name, Company.primary_contact, Company.website, (SELECT COUNT(1) FROM UserCompany WHERE approved = true and company_id = Company.company_id) AS user_count FROM Company;
This should give me this sample result:  So user_count is a result set from a subquery that was appended to the Company table. How would I go about adding a user_count property to the Company class that eager loads this subquery and attaches the result as a column whenever I run Company.query.all()? Notes: using Flask 2.0+, Flask-SQLAlchemy, Python 3.9 (that explains the @dataclass and the type hints in the Model properties)  |

DO NOT execute API call with put/post request }
and I'm passing a JSON file as my argument to this function, below is the content of the JSON file. Please note that this is not the full JSON data that I'm actually using. { "settings" : [ { "key" : "AccountingRules", "description" : "Accounting Rules settings", "context" : "Entity", "pathPattern" : "/accounting-rules", "httpOperations" : [ { "method" : "GET", "url" : "/settings/accounting-rules", "parameters" : [ ], "responseType" : { "$ref" : "#/definitions/AccountingRules", "definitions" : { "AccountingRules" : { "additionalProperties" : false, "type" : "object", "properties" : { "allowRevenueScheduleNegativeAmounts" : { "type" : "boolean" }, "allowBlankAccountingCodes" : { "type" : "boolean" }, "allowCreationInClosedPeriod" : { "type" : "boolean" }, "allowUsageInClosedPeriod" : { "type" : "boolean" }, "differentCurrencies" : { "type" : "boolean" } } } } } }, { "method" : "PUT", "url" : "/settings/accounting-rules", "parameters" : [ ], "requestType" : { "$ref" : "#/definitions/AccountingRules", "definitions" : { "AccountingRules" : { "additionalProperties" : false, "type" : "object", "properties" : { "allowRevenueScheduleNegativeAmounts" : { "type" : "boolean" }, "allowBlankAccountingCodes" : { "type" : "boolean" }, "allowCreationInClosedPeriod" : { "type" : "boolean" }, "allowUsageInClosedPeriod" : { "type" : "boolean" }, "differentCurrencies" : { "type" : "boolean" } } } } }, "responseType" : { "$ref" : "#/definitions/AccountingRules", "definitions" : { "AccountingRules" : { "additionalProperties" : false, "type" : "object", "properties" : { "allowRevenueScheduleNegativeAmounts" : { "type" : "boolean" }, "allowBlankAccountingCodes" : { "type" : "boolean" }, "allowCreationInClosedPeriod" : { "type" : "boolean" }, "allowUsageInClosedPeriod" : { "type" : "boolean" }, "differentCurrencies" : { "type" : "boolean" } } } } } } ] }, { "key" : "AgingBuckets", "description" : "Aging Buckets", "context" : "Entity", "pathPattern" : "/aging-buckets", "httpOperations" : [ { "method" : "GET", "url" : "/settings/aging-buckets", "parameters" : [ ], "responseType" : { "$ref" : "#/definitions/AgingBucket", "definitions" : { "Bucket" : { "additionalProperties" : false, "type" : "object", "properties" : { "name" : { "type" : "string", "maxLength" : 100 }, "fromDaysPastDue" : { "type" : "integer" }, "toDaysPastDue" : { "type" : "integer" } }, "required" : [ "name" ] }, "AgingBucket" : { "additionalProperties" : false, "type" : "object", "properties" : { "includeNegativeInvoice" : { "type" : "boolean" }, "buckets" : { "type" : "array", "items" : { "$ref" : "#/definitions/Bucket" } } } } } } } ] } ]}
And whenever I'm displaying the output for my variable named "method", the output that's being returned is stacked on top of one another. To give you an example, the issue looks like this when displaying the $method value. Display method below "PUT" "POST" "PUT" "POST" "PUT" "POST" "PUT" "POST" "PUT" "POST" "PUT" "POST" "PUT" "PUT" "POST" "PUT" "POST" "POST" "PUT" "POST" Done displaying method
Wherein I'm expecting the output to be just a single "PUT" or "POST" only. Also, the thing I observed that's kind of weird for me is that this issue will show up when I try to display my variable executing "$ echo ${method}" command but when I remove the curly braces it sometimes works fine.  |

| Deny CreateBucket in S3 unless AES256 Encryption Checked Posted: 15 Oct 2021 09:37 AM PDT I have been trying for the better part of a day. I am, as an administrator, attempting to require users to check the "Automatically encrypt objects when they are stored in S3" button (AES256) when creating their S3 buckets. I've tried about everything can think of. So far, I have only gotten 2 separate results. As a test user, I am either allowed to create buckets (with or without checking encryption), or I am denied (with or without checking encryption). The last effort has resulted in the following policy being applied to the test user, in which case I am denied creating a bucket whether or not I check the encryption box { "Version": "2012-10-17", "Statement": [ { "Sid": "VisualEditor0", "Effect": "Deny", "Action": [ "s3:CreateBucket" ], "Resource": "*", "Condition": { "StringNotEquals": { "s3:x-amz-content-sha256": "AES256" }, "Null": { "s3:x-amz-content-sha256": true } } ] }
I have combined the above policy with S3AllowFullAccess, with other custom policies allowing access, but I simply cannot get it to work. Any help is appreciated  |
| How do you change the icon of the `wwwroot` folder in a .NET Core project? Posted: 15 Oct 2021 09:37 AM PDT In Visual Studio 2017, when I want to create an ASP.NET Core Web Application from scratch using either one of these standard .NET Core project templates: - Console App (.NET Core)
- Class Library (.NET Core)
These project templates; obviously would not include the wwwroot folder. So, when I add the folder to my project it will look like (and behave like) a standard folder: 
When you create it using the ASP.NET Core Web Application project template, the wwwroot folder looks like this: 
Question - Appearance (Icon) How do you change the icon of the wwwroot folder to look like the one found in the ASP.NET Core Web Application project template?
Additional Question - Behavior (Copying Files to Output Directory)
In the standard .NET Core project, I would have to add this to my .csproj file: <ItemGroup> <Content Include="wwwroot\**" CopyToOutputDirectory="PreserveNewest" /> </ItemGroup>
so that it copies all my files from the wwwroot folder to the output directory similar to the ASP.NET Core Web Application project. I looked in the ASP.NET Core Web Application's .csproj file and didn't see anything like that. I'm assuming the answer to the main question will also provide the answer for this one, as the project templates are obviously different. I can't seem to find the resources online to help me manually edit this myself. Thanks in advance.  |
