It&#39;ll probably be best if you translate inside the controller for this one, unless you want to pass `element` and `minlength` to the template.

Firstly you&#39;ll need inject `$translate` into your controller. Then to generate your message:

    this.errorMessage = $translate(&#39;MINLENGTH&#39;, { element: element, value: minlength });

This method is also outlined [here](https://github.com/angular-translate/angular-translate/wiki/Dynamize-your-translations#passing-values-through-translate-service).

To do this in the template (outlined [here](https://github.com/angular-translate/angular-translate/wiki/Dynamize-your-translations#parametrizing-the-translate-filter)):

    {{ MINLENGTH | translate : { element: element, value: minlength } }}


For anyone wondering how the syntax is, for using methods to retrieve the input for translation, this worked for me: 

       {{ MINLENGTH | translate : { x: table.getShownCount(), y: table.getTotalCount() } }} 

You can also do this in the template like this.

    &lt;span data-translate=&quot;MINLENGTH&quot; data-translate-values=&quot;{ element: element, value: minlength }&quot;&gt;&lt;/span&gt;

You can also use `$translate.instant(&#39;MINLENGTH&#39;, { element: element, value: minlength })`

This worked fine for me:

    {{&#39;commisionMessage&#39; | translate : {fee:fee} }}|

Json File

    &quot;commisionMessage&quot;: &quot;BLA {{fee}} BLA BLA&quot;

How to add text input in alertview of ios 8?

I have so far avoided use of `log.Fatal`, but I recently co-incidentally discovered these questions; [code-coverage][1] and [tests-using-log-fatal][2].  

One of the comments from the 100 code coverage questions says: 

&gt; ... In the vast majority of cases `log.Fatal` should be only be used in main, or init functions (or possibly some things meant to be called only directly from them)&quot;

It go me thinking, so I began to look at the standard library code provided with Go.  There are lots of examples where the **test** code in the library makes use of `log.Fatal` which seems fine.  There are a few examples outside of the test code, such as in [`net/http`][3], shown below:

    // net/http/transport.go 
    func (t *Transport) putIdleConn(pconn *persistConn) bool {
        ...
    	for _, exist := range t.idleConn[key] {
    		if exist == pconn {
    			log.Fatalf(&quot;dup idle pconn %p in freelist&quot;, pconn)
    		}
        }
        ...
    }


If its is best practice to avoid use of `log.Fatal`, why is it used at all in the standard libraries, I would have expected just return an error.  It seems unfair to the user of the library to cause `os.Exit` to be called and not providing any chance for the application to clean-up.

I may be naive, so hence my question as a better practice would seem to be to call `log.Panic` which can be recovered and my theoretical long running stable application might have a chance of rising from the ashes.

So what would best-practise say for Go about when should log.Fatal should be used?

I have created a function that does some error checkings and will be used in different input fields. My function code is below:

    errorChecks = (element, minlength) =&gt; {
       if (element.$dirty) {
          if (element.$error.required == true) {
             this.errorMessage = &quot;REQUIRED&quot;;
             return;
          } else if (element.$viewValue.length &lt; minlength) {
              this.errorMessage = &quot;MINLENGTH&quot; // MINLENGTH error with parameters here
              return;
          } else {
              this.errorMessage = null;
              return;
          } 
       }
    }

I am using the angularjs translate for my error messages. 

    &quot;MINLENGTH&quot;: &quot;{{ element }} must be at least {{ value }} characters&quot;,

I wanted to dynamically change my error message by passing a parameter to the translations like so:

    errorChecks(username, 5);

If I enter 1 character to the username field the error would say: `username must be at least 5 characters`.

Is what I am trying to do even possible?

I&#39;m building a React app that has links pointing to predefined routes.

    &lt;a href=&quot;/my/react/route/&quot;&gt;Click Here&lt;/a&gt;

The routes resolve fine, but it&#39;s refreshing the page, thereby slowing down app performance. How do I avoid re-rendering the entire page?

    class PlayerControls extends React.Component {
      constructor(props) {

          shuffleActive: false,
        }
      }
    
      render() {
        var shuffleClassName = this.state.toggleActive ? &quot;player-control-icon active&quot; : &quot;player-control-icon&quot;

        this.setState({loopActive: !this.state.loopActive})
        this.props.onToggleLoop()
      }

I want to update `loopActive` state on toggle, but `this` object is undefined in the handler. According to the tutorial doc, I `this` should refer to the component. Am I missing something?

# My Issue
I&#39;ve coded a very simple CRUD API and I&#39;ve started recently coding also some tests using `chai` and `chai-http` but I&#39;m having an issue when running my tests with `$ mocha`.

When I run the tests I get the following error on the shell:

&gt; TypeError: app.address is not a function

## My Code

Here is a sample of one of my tests (**/tests/server-test.js**):

    var chai = require(&#39;chai&#39;);
    var mongoose = require(&#39;mongoose&#39;);
    var chaiHttp = require(&#39;chai-http&#39;);
    var server = require(&#39;../server/app&#39;); // my express app
    var should = chai.should();
    var testUtils = require(&#39;./test-utils&#39;);
    
    chai.use(chaiHttp);
    
    describe(&#39;API Tests&#39;, function() {
      before(function() {
        mongoose.createConnection(&#39;mongodb://localhost/bot-test&#39;, myOptionsObj);
      });
    
      beforeEach(function(done) {
        // I do stuff like populating db
      });
    
      afterEach(function(done) {
        // I do stuff like deleting populated db
      });
    
      after(function() {
        mongoose.connection.close();
      });
    
      describe(&#39;Boxes&#39;, function() {
    
        it.only(&#39;should list ALL boxes on /boxes GET&#39;, function(done) {
          chai.request(server)
            .get(&#39;/api/boxes&#39;)
            .end(function(err, res){
              res.should.have.status(200);
              done();
            });
        });
    
        // the rest of the tests would continue here...
    
      });
    
    });

And my `express` app files (**/server/app.js**):

    var mongoose = require(&#39;mongoose&#39;);
    var express = require(&#39;express&#39;);
    var api = require(&#39;./routes/api.js&#39;);
    var app = express();
    
    mongoose.connect(&#39;mongodb://localhost/db-dev&#39;, myOptionsObj);
    
    // application configuration
    require(&#39;./config/express&#39;)(app);
    
    // routing set up
    app.use(&#39;/api&#39;, api);
    
    var server = app.listen(3000, function () {
      var host = server.address().address;
      var port = server.address().port;
    
      console.log(&#39;App listening at http://%s:%s&#39;, host, port);
    });

and (**/server/routes/api.js**):

    var express = require(&#39;express&#39;);
    var boxController = require(&#39;../modules/box/controller&#39;);
    var thingController = require(&#39;../modules/thing/controller&#39;);
    var router = express.Router();
    
    // API routing
    router.get(&#39;/boxes&#39;, boxController.getAll);
    // etc.
    
    module.exports = router;

### Extra notes

I&#39;ve tried logging out the `server` variable in the **/tests/server-test.js** file before running the tests:

    ...
    var server = require(&#39;../server/app&#39;); // my express app
    ...
    
    console.log(&#39;server: &#39;, server);
    ...

and I the result of that is an empty object: `server: {}`.

I am trying to create a `PDF` from my HTML using `pdfMake` and `Angular` (I&#39;ve also tried `jsPDF` and couldn&#39;t get it to work either).  I tried using the following code in my Angular controller:

        

    var blob = new Blob([document.getElementById(&#39;exportable&#39;).innerHTML])
    var docDefinition = {
        content: [blob]
    }
    pdfMake.createPdf(docDefinition).open();

but I receive the following error: 

&gt;Unrecognized document structure: {&quot;_margin&quot;:null}&quot;.

My HTML consists of two simple tables in a div `exportable`.

If anyone knows a solution to this issue, or another way to get the HTML into a PDF from Angular, PLEASE help.

Any assistance is GREATLY appreciated!

Generate PDF from HTML using pdfMake in Angularjs

Months ago, I decided to study Angular. When I was doing some advance and create some app using it, I realize that Angular 2 is in Developer preview, so it&#39;s a matter of time before it&#39;s going to be released. Because Angular 2 is not going to be compatible with Angular 1, and there are a lot of changes, the question is, is it better to continue developing with Angular 1.x or start developing Angular 2?

It&#39;s a fact that we don&#39;t always have to be using the latest version nor the newest language on the market, but in this case, the app is still small so I could change without problems. 

AngularJS vs Angular

I have seen a syntax like

I&#39;m a bit fuzzy on these concepts, If I build the same ToDo app completely in AngularJS and ReactJS--- what makes the React ToDo use one-way data binding vs the AngularJS&#39;s two-way data binding?

I understand that React sort of works like 

Render(data) ---&gt; UI.

How is this different from Angular?


Can anyone explain the difference between Reacts one-way data binding and Angular&#39;s two-way data binding

In AngularJS you were able to specify watchers to observe changes in scope variables using the `$watch` function of the `$scope`. What is the equivalent of watching for variable changes (in, for example, component variables) in Angular?
