Pass empty fields on the update method using Laravel Request

2018-07-12 05:55 shAkur imported from Stackoverflow

I'm getting data through a classic submitted form but for some reason I don't get all the input's data in request and it only updates the received ones.

Model::find($id)->update($request->all());

This is a bit problematic because I have multiple nullable fields in my database and sometimes I want to pass empty fields (i.e when a user clear an input then submit the form)

Do you know a way to pass empty fields to the Request as well?

The thing is, Laravel transforms the '' values to null by default through the ConvertEmptyStringsToNull middleware. Check your Kernel:

app/Http/Kernel.php
```
protected $middleware = [
    // some middlewares..
    \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,
    // some more middlewares..
];
```
This middleware do the following:
```
protected function transform($key, $value)
{
    return is_string($value) && $value === '' ? null : $value;
}
```
As you can see, if the given attribute has a value '' it will be transformed to null.

So, to avoid this you could just comment that middleware in the Kernel file. But be aware of this, because this will be applied to your entire application.

You can use php array_merge() like with this code as i use that

$contentCategory->update(array_merge($request->all(), ["FIELD1" => '',"FIELD2" => '']));

or test this code:

$request->request->add(['FIELD1' => '','FIELD2' => '']);

Input Trimming & Normalization
Laravel version > 5.4 already has these features included:

For versions < 5.4: make a new middleware with following code:
```
public function handle($request, Closure $next)
{
    foreach ($request->input() as $key => $value) {
        if (! $value) {
            $request->request->set($key, NULL);
        }
    }

    return $next($request);
}
```
and assign it to the routes or controller's methods you want it to take place:
```
Route::post('/route/{id}', [
   'middleware' => NewMiddleware::class,
], function (Request $request, $id) {
    Model::find($id)->update($request->all());
});
```
REMEMBER: create(), update(), etc. methods work on fields in $fillable array in your model. If your field is not in the $fillable array in "Model" class, the update() method will not work for that field!!!

how to call postgresql function with array parameter from laravel

I've error in laravel when I call postgresql function with array parameter from laravel.

this is my function :

CREATE OR REPLACE FUNCTION public.get_eprop_break_data(

This is how I call the function from laravel

$TestGetFunc = DB::select('select * from get_eprop_break_data(?,?,?,?)',[$division_id,$det_prop_brand,$det_prop_activity,$det_prop_varian]);

and this is the Error :

Laravel 5.6: config/logging.php file is missing?

In the docs of Laravel 5.6 its stated here that one can config his logging channels in config/logging.php. I have updated from Larvel 5.5 to Laravel 5.6 but I could not find this config file.

Do I need to call a special artisan command for this or something like that?

Laravel flash message not working in specific method on specific redirect route

I have pretty strange problem. My flash message isn't working when I create post, but works when I delete or update it, it also works when I change redirect direction.

So in store() method when I save created post to DB I then redirect to /posts, redirect happens but no flash message, if I change it from /posts to /anyotherroute it works.

My update() is identical to store() and it also redirects to /posts but flash message appears in case of update, same with destroy().

Anyone knows why is that ?

So i just noticed that on localhost flash message appears, but on shared hosting it doesn't.

Store()

Validation using GlobalKey<FormState> in individual steps of Flutter Stepper widget returns false even for correct input

I am using stepper widget, and using a Form widget in each step of stepper with different form keys in order to validate each step ... the problem is that this._formKey.currentState.validate() always returns false even if the validation criteria fulfills for the current step ... following is the code that i use to build individual steps in stepper:

    }

    if(isset($_POST['submit']))
    {
     $textareaValue = trim($_POST['information']);
      $sql="INSERT INTO technical_support(ApplicantName, BuildingNo, FloorNo, 
      EXTPhone,  ReportDate,  PlaceOfApp, TechInfo,Notes)VALUES('".inputName."','".inputBuilding."','".inputFloor."','".inputEXT."','".inputDateS."','".inputApp."','".$textareaValue."','".$textareaValue1."')";

EditorInfo null after startActivity from InputMethodService

I am having the following problem. My InputMethodService starts an Activity through startActivity and I have a ResultsReceiver that gets a result from the Acivity. I want this result to get printed out in the chatbox with commitText(). This didn't work in the sense that nothing was printed out.

Next I checked getCurrentEditorInput().dump() and noticed that a lot of the values are null. So I am thinking the Editor is somehow broken and that's why it doesn't work.

Here is some of the relevant code for reference.

I am pretty frustrated with being not able to fix that. Does anyone have any idea or knowledge if one can fix that?
iOS style input field
So I'd like to create an input field like the iOS one to input a numeric verification code with 6 characters. You can find an example right below (please have a look at the highlighted green one).

What is really important to me is that there is a bigger gap between the first 3 characters and the last 3 characters than between the other single letters.

What is also unumgebar is that I probably can not use multiple input fields, because I would like to execute the keyboard inputs like "delete" anyway. Auserdem I do not want to have to click each fled individually when you enter the code.

Note: What I'd like to achieve is an exact copy of the input field on the screenshot above.

What I've found so far is something like you can find in the snippet below. Two problems: 1. It looks like the input field is a bit buggy because it displays some pixels of another underlined field that shouldn't get displayed. 2. Theres no gap between the first three and the last three fields. (The one with the placeholder="3" should not be displayed.
```
input {
  border: none;
  width: 10.5ch;
  background: 
    repeating-linear-gradient(90deg, 
        black 0, 
        black 1ch, 
        transparent 0, 
        transparent 1.5ch) 
      0 100%/100% 2px no-repeat;
  font: 5ch consolas, monospace;
  letter-spacing: .5ch;
}
```
```
<input maxlength='7' value='' placeholder="01234567"/>
```
Any help would be really appreciated. Thanks a million in advance.

Edit 1: @Lorddirt - Inputting the last number of one block will made all absolutely jerky as you can hopefully see in this gif:

Edit 2: @Lorddirt - see this image:

I'm pretty sure you mixed some calculations but theres the overflow pixel occurrence. Furthermore you've fixed the "looking jerking bug" for the first input but not for the second one. Too bad. Thanks so much anyways :)

Exposing Prometheus logs to endpoint

I am using Python library prometheus_client for tracking data of my app.

I collect metrics (Gauge/Counter etc.) in CollectorRegistry.

I have http_server with BaseHTTPRequestHandler correctly running and returning data on various endpoints.

I would like to know how to expose data stored via CollerctorRegistry on my endpoint.

from http.server import BaseHTTPRequestHandler, HTTPServer
from prometheus_client import generate_latest, CONTENT_TYPE_LATEST

class MyLogHandler(BaseHTTPRequestHandler):
    def _set_headers(self):
        self.send_response(200)
        self.send_header("Content-type", "text/html")
        self.end_headers()

    def do_GET(self):
        if ENDPOINT_MANAGE_HEALTH in self.path:
            status_code = 200 if ServiceStatusStore.all_services_healthy() else 500
            self.send_response(status_code)

            self.send_header("Content-Type", "application/json; charset=utf-8")
            self.end_headers()

            response_content = ServiceStatusStore.get_status_json()
            self.wfile.write(response_content.encode("utf-8"))

        if ENDPOINT_PROMETHEUS in self.path:
            data = generate_latest(PrometheusGlobalRegistry.GLOBAL_REGISTRY)

            self.send_header("Content-Type", CONTENT_TYPE_LATEST)
            self.send_header("Content-Type", str(len(data)))
            self.send_response(200)

            return iter([data])

        else:
            self.send_response(500)

I've included ENDPOINT_MANAGE_HEALTH because it properly works and returns JSON.

My ENDPOINT_PROMETHEUS is being asked for data and returns status 200 but no data from CollertorRegistry is passed. I don't know what should be the data format and how it should be passed.

My current solution is a n-th try after reading example on GitHub Readme of the library.

Node.JS: How To Use A Percent Sign In A URL Request?

Issues connecting to OAuth2 API from Node.js/Javascript?

I am trying to connect to the Freshbooks API using OAuth2 and I'm not sure why it is not working. https://www.freshbooks.com/api/authentication

I started using the simple-oauth2 library: https://github.com/lelylan/simple-oauth2 so I created the following in my app.js:

const oauth2 = simpleOauthModule.create({
    client: {
        id: process.env.CLIENT_ID,
        secret: process.env.CLIENT_SECRET,
    },
    auth: {
        tokenHost: 'https://api.freshbooks.com',
        tokenPath: '/auth/oauth/token',
        authorizePath: 'https://my.freshbooks.com/service/auth/integrations/sign_in',
    },
});

//authorization uri definition
const authorizationUri = oauth2.authorizationCode.authorizeURL({
    redirect_uri: 'https://localhost:3000/callback',
    //scope: 
    //state:
});

//initial page redirecting to freshbooks
router.get('/auth', function(req, res) {
    console.log('Inside /auth');
    console.log(authorizationUri);
    res.redirect(authorizationUri);
});

//callback service parsing the aurothization token and asking for access token
router.get('/callback', async (req, res) => {
    console.log('Inside /callback');
    const code = req.query.code;
    const options = {
        code,
    };

    try {
        const result = await oauth2.authorizationCode.getToken(options);
        console.log('The resulting token: ', result);

        return res.status(200).json(token);
    } catch(error) {
        console.error('Access token error', error.message);
        return res.status(500).json('Authentication failed');
    }
});

Now I have a button which when pressed calls the /auth route. This opens up the Freshbooks login page, however, once I enter my credentials and click sign in nothing happens, the form stays open and I receive no response back to my app.

Am I missing something? What should I be expecting to happen? Is this an issue with Freshbooks rather than my code?

Is there a better way to do this rather than using the simple-oauth2 library?

Thanks for the help!

Triggering submit button with Enter keypress event and mouse click

I have been stuck on the issue for a dozen hours over a course of days. I am at a loss! I am a total beginner and am learning front-end using a "just do it" and project-focus route.

My Web app will essentially work similar to that of a to-do list.

I assume it is because I have "getElementById" twice for the same element.

This works initially:

// add idea to list button

document.getElementById('btnSubmit').addEventListener("submitIdea", submitIdea);

function submitIdea() {
    var ul = document.getElementsByClassName('anIdea')[0];
    var enterIdea = document.getElementById('enterIdea');
    var li = document.createElement('li');
    li.setAttribute('class', enterIdea.value);            
    li.appendChild(document.createTextNode(enterIdea.value));
    ul.prepend(li);
    li.contentEditable = 'true';
};

But then, when I add this code, I am unable to write anything at all in my input box:

// use enter key to submit new li item

document.getElementById("enterIdea").addEventListener('keypress', function(event) {
    event.preventDefault();
    if (event.keyCode === 13) {
        document.getElementById('btnSubmit').click();
    }
});

Javascript program that shows a message after inputting age, but function doesn't work

I'm trying to make a fairly easy site/program that receives a number from an input, and after submitting using a button, shows the user a message based on their input. I feel as though it should be fairly easy, but I'm having a lot of errors, such as: Cannot set property 'innerHTML' of null. And as I tried fixing these errors (adding return false? to onsubmit on form, changing variables and syntax, etc.) I feel as if I am more stuck. I'm not sure how to make it work.

(Ignore the lastInn function, as it is something I did myself just to test if I could do it.)

Here is the html code:

<form onsubmit="return false" action="">
    <input type="number" name="inputAld" id="inputAld">

    <button type="submit" id="trykkAld" disabled="disabled" onsubmit="visAlder();">trykk på meg</button>

</form>

<p id="visHer"></p>

And here is the javscript file:

var vis, trykk; 

function lastInn() {
var but;
but = document.querySelector("#trykkAld");
but.disabled = false;
}


trykk = document.getElementById("trykkAld");
vis = document.getElementById("visHer");

document.getElementById("visHer").innerHTML ="";

function visAlder() {
  var ald;
  ald = document.getElementById("inputAld").value;

  if (ald > 10) {
    vis.innerHTML = "Du er et ungt barn";
  }
  else if (ald < 10 && ald > 18) {
    vis.innerHTML = "Du er en tenåring";
  }
  else if (ald <= 18 && ald > 30) {
    vis.innerHTML = "Du er en ung voksen";
  }
  else if (ald <= 30 && ald > 60) {
    vis.innerHTML = "Du er voksen";
  }
  else if (ald <= 60 && ald < 70){
    vis.innerHTML = "Du begynner å dra på åra"
  }
  else if (ald <= 70) {
    vis.innerHTML = "Du er nok gammel";
  }
  else {
    vis.innerHTML = "Hva faen er du for noe?";
}

}

Edit: I fixed the operators in my document.
