react-native-router-flux drawer changing scenes

Sat, 07/08/2017 - 18:13

I'm trying to use react-native-flux with tabbar and navbar, but the scene change works strange. The first time I press each option in the drawer it works, not the second. Also if I return to the 'Main' scene, the 'drawerImage' doesn't apply and renders the default one.

Any help will be appreciated!

This is my router file

import React, { Component } from 'react'; import { Text } from 'react-native'; import { Router, Scene } from 'react-native-router-flux'; import SplashPage from './SplashPage'; import Start from './Start'; import Drawer from './Drawer'; import ClientNoLogged from './ClientNoLogged'; import NoLogged from './NoLogged'; import Login from './Login'; import SignUp from './SignUp'; import Forgot from './Forgot'; import Pending from './Pending'; import Answered from './Answered'; import OtherRequests from './OtherRequests'; import Reviews from './Reviews'; import Profile from './Profile'; import STYLES from '../core/Styles'; class TabIcon extends React.Component { render(){ return ( <Text style={{color: this.props.selected ? 'white' :'#ff514f'}}>{this.props.title}</Text> ); } } export default class App extends Component { render() { return ( <Router> <Scene key="root"> <Scene key="SplashPage" panHandlers={null} component={SplashPage} initial={true} hideNavBar={true} /> <Scene key="Start" panHandlers={null} component={Start} hideNavBar={true} /> <Scene key="ClientNoLogged" panHandlers={null} component={ClientNoLogged} hideNavBar={false} backButtonImage={require('../img/back.png')} navigationBarStyle={[STYLES.navBar]} navigationBarTitleImage={require('../img/logoSplash.png')} navigationBarTitleImageStyle={[STYLES.navBarLogo]} /> <Scene key="NoLogged" panHandlers={null} component={NoLogged} hideNavBar={true} /> <Scene key="Login" panHandlers={null} component={Login} hideNavBar={true} /> <Scene key="Forgot" panHandlers={null} component={Forgot} hideNavBar={true} /> <Scene key="Signup" panHandlers={null} component={SignUp} hideNavBar={true} /> <Scene key="Drawer" component={Drawer} open={false}> <Scene key="Main" tabs={true} tabBarSelectedItemStyle={STYLES.tabSelected} tabBarStyle={STYLES.tabBar}> <Scene key="tab1" initial={true} title="Pending" icon={TabIcon}> <Scene key="tab1_1" component={Pending} panHandlers={null} drawerImage={require('../img/burger.png')} navigationBarStyle={[STYLES.navBar]} navigationBarTitleImage={require('../img/logo.png')} navigationBarTitleImageStyle={[STYLES.navBarLogo]}> </Scene> </Scene> <Scene key="tab2" title="Answered" icon={TabIcon}> <Scene key="tab2_1" component={Answered} panHandlers={null} drawerImage={require('../img/burger.png')} navigationBarStyle={[STYLES.navBar]} navigationBarTitleImage={require('../img/logo.png')} navigationBarTitleImageStyle={[STYLES.navBarLogo]}> </Scene> </Scene> </Scene> <Scene key="OtherRequests" drawerImage={require('../img/burger.png')} navigationBarStyle={[STYLES.navBar]} navigationBarTitleImage={require('../img/logo.png')} navigationBarTitleImageStyle={[STYLES.navBarLogo]}> <Scene key="OtherRequestsBody" component={OtherRequests} panHandlers={null}> </Scene> </Scene> <Scene key="Reviews" drawerImage={require('../img/burger.png')} navigationBarStyle={[STYLES.navBar]} navigationBarTitleImage={require('../img/logo.png')} navigationBarTitleImageStyle={[STYLES.navBarLogo]}> <Scene key="ReviewsBody" component={Reviews} panHandlers={null}> </Scene> </Scene> <Scene key="Profile" drawerImage={require('../img/burger.png')} navigationBarStyle={[STYLES.navBar]} navigationBarTitleImage={require('../img/logo.png')} navigationBarTitleImageStyle={[STYLES.navBarLogo]}> <Scene key="ProfileBody" component={Profile} panHandlers={null}> </Scene> </Scene> </Scene> </Scene> </Router> ) }

Not able to access protected variables

Sat, 07/08/2017 - 18:05

I have created a simple test project to use a class as a custom List type and have a couple of questions regarding the use of different syntax when declaring variables.

I have a class called CustomerInfo which defines all the variables required to be stored for the customer information which will be added to a list as seen below:

protected string Firstname { get; set; } protected string Surname { get; set; } protected int Age { get { return Age; } set { if(value < 0) { throw new AgeException("Age cannot be a value below 0"); } else { Age = value; } } } protected string Gender { get; set; }

Questions:
1) Why does the code below not allow me to access the protected variables in the CustomerInfo class even though I am inheriting the class?

class Program : CustomerInfo { static void Main(string[] args) { CustomerInfo custInfo = new CustomerInfo(); custInfo.Firstname = "Richard"; //not working custInfo.Surname = "Smith"; //not working List<CustomerInfo> custList = new List<CustomerInfo>(); custList.Add(custInfo); } }

2) When looking at Windows Forms applications they already contain an inheritence of Form in the code of any Form you create. If you have to inherit a class to access the protected variables & methods it has, how can you access the variables if each form already has an inheritance that you cannot remove?

Thanks

Why do we need a Scanner Object for taking input in java

Sat, 07/08/2017 - 17:56

In Java

To print output we simply use System.out stream while to take input, we have to pass System.in in Constructor of a Scanner object and then use that object only. Why is it so ? Why is there no direct method like System.in.nextInt() or Something ?

ps: I'm a newbie

Angular JS : Failed to instantiate module test due to:

Sat, 07/08/2017 - 17:50

I'm running some Javascript inside a HTML file. And I'm trying to use some Angular JS with the function ng-repeat. Each time I run it, I get this error in the console :

angular.js:38 Uncaught Error: [$injector:modulerr]

And when I click on the link within the error message in the console, I get this:

Here is my Javascript inside my HTML file:

//Get User ID and Trip ID in URL function GetURLParameter(sParam) { var sPageURL = window.location.search.substring(1); var sURLVariables = sPageURL.split('&'); for (var i = 0; i < sURLVariables.length; i++) { var sParameterName = sURLVariables[i].split('='); if (sParameterName[0] == sParam) { return sParameterName[1]; } } } var userid = GetURLParameter('userid'); var tripid = GetURLParameter('tripid'); </script> <script> //Get photos URL inside a particular Trip ID from a User ID var database = firebase.database(); database.ref(`photos/${userid}/trips/${tripid}`).once('value') // will return you all the photo objects inside the `tripId` .then(photosSnap => { var photosObj = photosSnap.val(); var photosUrl = Object.keys(photosObj).map(key => photosObj[key].photourl); // then you can return the array or use it here; var app = angular.module('test', []); app.controller('MainCtrl', function($scope) { $scope.urls = photosUrl; }); console.log(photosUrl); // will be an array of all the photourls }).catch(err => alert(err));

And finally my HTML which uses ng-repeat:

<div class="spot" ng-app="test" ng-controller="MainCtrl"> <ul> <li ng-repeat="url in urls">{{url}}</li> </ul> </div>

I'm using a controller with scope to loop inside my HTML with an array. So first I don't know where my error message comes from, and second I'm not sure i'm using the controller and ng-repeat properly.

Thanks

PS: I included in the head tag of my HTML file this link :

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>

Why is this html photo gallery not centering?

Sat, 07/08/2017 - 17:43

I'm trying to put a photo library on my webpage but it just won't center properly and it's driving me nuts. Any suggestions? I've tried putting so many different things for centering in the code but nothing works :/

JSF backing bean method not invoked [duplicate]

Sat, 07/08/2017 - 17:29

This question already has an answer here:

Here is my bean responsible for adding data from the selectOnemenu JSF.

public void add() { // ... } public Map<String, String> getFloorP() { return floorP; } public Map<String, String> getBedr() { return bedr; } public Map<String, String> getHouseType() { return houseType; } public Map<String, String> getItems() { return items; }

Now, this is my JSF XHTML code:

<h:form > <div class="col-md-6"> <div class="panel panel-default"> <div class="panel-heading"> <p> <label>MOVING FROM</label> </p> </div> <div class="panel-body"> <div class="form-group"> <label>Phone Number</label> <h:inputText value="#{ctrl.pnumber}" class="form-control req-input" pt:placeholder="Full Name" /> </div> <div class="form-group"> <label class="">Address</label> <h:inputText value="#{ctrl.address}" class="form-control req-input" pt:placeholder="Full Name" /> </div> <div class="form-group"> <label class="">State</label> <h:selectOneMenu value="#{ctrl.country}" class="form-control select" title="From State" required="true"> <f:selectItem itemValue="#{null}" itemLabel="-- select state --" /> <f:selectItems value="#{ctrl.items}" /> </h:selectOneMenu> </div> <div class="form-group"> <label>Type of Apartment</label> <h:selectOneMenu value="#{ctrl.house}" class="form-control select" title="From Type" required="true"> <f:selectItem itemValue="#{null}" itemLabel="-- select apartment --" /> <f:selectItems value="#{ctrl.houseType}" /> </h:selectOneMenu> </div> <div class="form-group"> <label>How many Bedrooms?</label> <h:selectOneMenu value="#{ctrl.room}" class="form-control select" title="From Beds" required="true"> <f:selectItem itemValue="#{null}" itemLabel="-- select bedrooms --" /> <f:selectItems value="#{ctrl.bedr}" /> </h:selectOneMenu> </div> <div class="form-group"> <label>On what floor is this apartment?</label> <h:selectOneMenu value="#{ctrl.floor}" class="form-control select" title="From Floors" required="true"> <f:selectItem itemValue="#{null}" itemLabel="-- select apartment floor --" /> <f:selectItems value="#{ctrl.floorP}" /> </h:selectOneMenu> </div> </div> </div> </div> <h:commandButton value="Add" actionListener="#{ctrl.add()}"/> </h:form>

I have tried to run it, but the add() method is not invoked, I don't know what's wrong with the code.

Wrong redirection Uri with Google OAuth2

Sat, 07/08/2017 - 17:16

I have been working in a web Symfony app that uses a google oauth2. Well, to use it I had to create a Client and a Secret id for development environtment.

The redirection uri is:

http://melomaniacs.com/app_dev.php/validate/

and it is working properly. When I finish and put on a EC2 instance, I created a new Client an Secret id for a production environment and set them properly on parameters, and the uri is:

http://www.melomaniacsweb.com/validate/

The problem is google is redirecting to the dev one uri, not the new one.

I tried: php bin/console cache:warmup --env=prod clearing the browser cache

Anybody know why this behaviour?

Thanks

Where to place tsconfig.json in Symfony Encore to define TypeScript config?

Sat, 07/08/2017 - 17:15

Symfony Encore now supports using TypeScript by default (Add support to enableTypescriptLoader), and it works great. However, I would like to configure my TypeScript configuration using a tsconfig.json file.

I tried figuring out where to place this, but I got lost in the rabbithole and didn't figure out where I should place the file for ts-loader to pick it up. Or if there is a configuration that enables this.

Flex-grow having no effect on flex-items [on hold]

Sat, 07/08/2017 - 16:53

Edited for clarity: I've assigned a div to be a flex container, and thus the direct children (two div containers inside it) should be flex-items. I should be able to assign a flex-grow value to these items to manipulate how much space they take up in a row. My goal is for the image to take up approximately 1/5 of the space, while the text takes up about 4/5. However, it appears that my assigned flex-grow values are having no effect, as my image stubbornly stays the same size and the text resizes around it.

Edited typo: There was a stray 'pre' tag in my code here as I was trying to paste it in. That 'pre' tag is not in MY code, and I've deleted it from here.

Edited image: Before I had a link to an image that visitors could not see, as it is hosted on my machine. I've updated the image src to include an image hosted online of approximately the same dimensions, so that visitors could (hopefully) see and reproduce the problem via Run Code Snippet.

Edited pargraph: Added more text to accentuate the problem.

I do have a max-width set on the container, but turning that off doesn't appear to allow the flex to work either, so I don't think it's conflicting.

Here is my code:

.home-div { display: flex; max-width: 900px; margin: auto; } div.portrait { flex-grow: 1; } div.welcome-text { flex-grow: 3; } .rj { max-height: 500px; } <div class="home-div lg-pad"> <div class="portrait"> <img src="http://runners.worldofo.com/bilder/large/tovealexandersson_WOC2012MiddleFinal%2015.jpg" class="rj sm-pad"> </div> <div class="welcome-text sm-pad"> <h1>Rebecca Jensen</h1> <h3>UX/UI Designer</h3> <p>Keytar art party food truck tofu salvia pork belly.

It seems that the image is the source of the problem, but I don't know what about it is causing the problem.

Sudden memory expansion between 2 inits. Can go log chronilogical functions called?

Sat, 07/08/2017 - 16:48

I have a routing package that inits multiple others. When I log all the inits I get the following order of output:

Initializing Config.. Initializing Countries.. Initializing Languages.. Initializing Globals.. Initializing Translations.. Initializing Tokenpool.. Initializing Mail.. Initializing Routing..

If I halt-loop at the end of tokenpool the memory is 7MB. At the beginning of mail it's suddenly 24MB.

Besides pprof memory tracing, is there a runtime-style tactic to get a big trace, until some runtime.StopTrace() kind-of-thing gets called, that will show all functions that have been called?

Not sure what to do. Thanks.

Twig table get id outside for loop

Sat, 07/08/2017 - 15:01

I'm trying to access to the user id outside my for loop in twig

The line <button " class="btn btn-add btn-sm"><a style="color:#fff;" href="{{ path('lemon_user_deleteuser', {'id': userid}) }}">YES</a></button>

always returns the last id (15 if i have 15users in my DB) no matter on which line the button is clicked

i know how to do this with jquery/ajax and from scratch php but since im new to symfony/twig im kinda lost

Localhost Service Discovery For a Custom XEP-0114 Component in Prosody or ejabberd

Sat, 07/08/2017 - 09:52

I have written a silly hello-world XEP-0114 component and got it connected to Prosody and ejabberd. Now I want to use service discovery to announce presence of the service and provide instructions about its usage.

So I seek a way to make it discoverable for anyone with a JID, remote or local, to provide more details about it.

For Prosody I do:

Component "foo.localhost" component_secret = "secret" disco_items = { { "foo.localhost", "FOO BAR" }; }

For ejabberd I do:

modules: mod_disco: extra_domains: - "foo.localhost" - "localhost" server_info: - modules: all name: "abuse-addresses" urls: - "foo.com" listen: - port: 8888 module: ejabberd_service access: all shaper_rule: fast ip: "127.0.0.1" hosts: "foo.localhost": password: "secret"

Then in Gajim I start service discovery on localhost and get error:

There is no service at the address you entered, or it is not responding. Check the address and try again.

What do I miss?

Angular 4 Refresh section of page only

Hi community I have a Plunker where I have implemented this flow:
