I'm currently using laravel and my website is just working fine
But upon hosting it I'm getting a problem internal server error but I figured out what the problem is, it's inside the controller
public function update(Request $request, $id)
{
$patient = Patient::find($request->id);
$patient->$request['col'] = $request->value;
$patient->save();
}
the $request['col'] is the one i passed from my inline table editor plugin and
here is the code:
$('.edit').editable('posts.update', {
event: 'click',
indicator : 'saving ...',
select : true,
submitdata : function(value, settings) {
return {_method: "PUT",_token:token,col:$(this).attr("class").split(' ')[1]};
},callback : function(value, settings) {
$(this).addClass('success');
}
});
I get class of an element col:$(this).attr("class").split(' ') and passing it to the update function so it will dynamically update the column of the database
But after hosting it to heroku I'm getting an error so i have tried putting a column name statically $patient->name = $request->value; and it's working fine then i have tried storing the name column to a variable to figure out what is really the problem $name = 'name'; then $patient->$name = $request->value; then I get the error again.

When trying to update a resource in Laravel Nova that has a Observer the update loads for a while and then ends with a 502 error. The observer is registered correctly (the created method works fine) and I'm not trying to do anything special in the updated method. Any ideas?
public function updated(Model $model)
{
//
$model->title = 'test';
$model->save();
}
If I try this without the $model->save(), there is no 502 error but the change I want to happen also doesn't happen. I get the green success message, and any change I make on the form prior to updating occurs, but not the change I'm trying to make during the updated method.
Any help troubleshooting this would be appreciated
I am not very good at Laravel, but I think, that you should to try this:
In your model file add method:
public function saveQuietly(array $options = [])
{
return static::withoutEvents(function () use ($options) {
return $this->save($options);
});
}
Then, in your updated method in observer do something like this:
public function updated(Model $model)
{
$model->title = 'test';
$model->saveQuietly();
}
I'm trying to create waitlist to buy product, but change the status of the transaction from 'Confirmed' to 'Waitlist'.
For that I have added a variable 'status' and a function in Transaction Model as follows:
const CONFIRMED_TRANSACTION = 'confirmed';
const WAITLIST_TRANSACTION = 'waitlist'; //waitlist product
public function isConfirmed() {
return $this->status == Transaction::CONFIRMED_TRANSACTION;
}
Default value of Transaction->status is 'CONFIRMED_TRANSACTION'.
Now every time the Product->status changes to 'unavailable' i would like to change the value of the Transaction->status to 'WAITLIST_TRANSACTION' when the transaction is created.
I am trying to achieve it using Event Listeners as:
Transaction::created(function($transaction) {
if(!$product->isAvailable()) {
$transaction->status = Transaction::WAITLIST_TRANSACTION;
$transaction->save();
}
});
But this gives me error :
**ErrorException: Undefined variable: product in file /home/vagrant/restfulapi7/app/Providers/AppServiceProvider.php on line 29**
How can I achieve the same in a better way?
You're using what's called a lambda or anonymous function, which has a different scope to the rest of your code.
function($transaction) does not have access to a variable named $product. So you're trying to call ->isAvailable() on a variable which doesn't exist.
Transaction::created(function($transaction) {
if(!$product->isAvailable()) {
$transaction->status = Transaction::WAITLIST_TRANSACTION;
$transaction->save();
}
});
Assuming it exists in the scope in which you call Transaction::created(), you can pass the $product variable into your lambda function like this:
function($transaction) use ($product) { ... }
For more information on lambda functions, read the php docs here
This solves the issue:
if(!$transaction->product->isAvailable())
I have a strange situation where eloquent model won't let me update nor destroy while index and create is working fine!
I'm using Vue.js and Laravel API Resource for form control, and while it worked with me before, it won't work here:
Here's my Vue.js Code:
updateFinish(finish) {
axios.patch(`/api/finishes/${finish.id}`, finish).then(response => {
this.fetchFinishes();
}).catch(error => {
// Get laravel validation error
this.errors = error.response.data.errors;
});
},
laravel update code (not working)
public function update(FinishType $finishType)
{
// Don't know why not working
$finishType->update($this->validateRequest());
return new FinishTypeResource($finishType);
}
the response is null:
{"id":null,"name":null}
While this code works:
public function update($id)
{
$finishType = FinishType::find($id);
$validates = $this->validateRequest();
$finishType->name = $validates['name'];
$finishType->save();
return new FinishTypeResource($finishType);
}
public function validateRequest()
{
return request()->validate([
'name' => 'required | unique:finish_types',
]);
}
Note the Model name is FinishType and database table name is finish_types, I even tried to define the table name in the model like so protected $table = 'finish_types' – still not working and I already have defined the $fillable array!!!
Your route model binding is not working correctly, for the implicit binding to work your injected variable should match the route parameter name.
Assuming that your parameter name could be finish (reading the url from your javascript) you have to write the update function using $finish as injected variable, like this:
public function update(FinishType $finish)
{
$finish->update($this->validateRequest());
return new FinishTypeResource($finish);
}
Do the same for destroy():
public function destroy(FinishType $finish)
{
// your destroy code here
}
In any case you can run php artisan route:list to find your parameter name (the part of the URI in braces) and give the same name to the injected variable.
If the two do not match, parameter and injected variable name, laravel injects a void, not loaded, FinishType model so it does not make sense doing an update or a delete on it.
I can't post comments so I'm going to post what I assume is the answer.
Laravel does route model binding automagically when the route url name corresponds to the name of the table I think... or model.
So users/{id} would auto bind the User object when you type it as a param in the controller. Example (User $user)
However, since your URL seems to be "different" from the name of your Model/Table, go to the RouteServiceProvider, and manually do the binding.
So in your case you'd do something like this in the boot function of the RouteServiceProvider class:
public function boot()
{
parent::boot();
Route::model('finishes', FinishType::class);
}
Don't forget your imports :)

I have the following issue when I try to update the laravel table I send my data via ajax everything is good. But the update returns an error.
the following function receives the data and updates the table.
public function saveCalendar(Request $request) {
$calendar = $request->calendar;
$apartment_id = $request->apartment_id;
apartments::where('Apartment_ID', $apartment_id)->update(array('calendar' => $calendar));
$confirmation = 'Календара е запазен успешно !';
return $confirmation;
}
I also tried this query:
apartments::where('Apartment_ID', $apartment_id)->update('calendar' => $calendar);
Any idea what am I doing wrong.
Error is because update function accepts array. Correct syntax is
apartments::where('Apartment_ID', $apartment_id)->update(['calendar' => $calendar]);
Also the correct syntax for fetching resquest inputs are
$calendar = $request->input('calendar');
$apartment_id = $request->input('apartment_id');
I am intentionally making error i.e. using one of the coulmn's name wrong to learn how to handle the error with ajax call with codeigniter.
Last Comment in controller function at the end is my question/problem
My AJX Code is following. I am using ajaxform plugin. It shows me all response from controller perfectly but problem is only I am unable to get response from model in controller while using ajax call that is little weird
$('#myForm').ajaxForm
({
success: function(responseText)
{
if(responseText != "1")
$('#feedback').html(responseText);
}
});
Following is snapshot of exact error which i can see in console but unable to get in controller and hence in view. It describes complete error i.e unknown column in given query, but i captured only upper portion.
My model function is below
public function updateItem($id, $data, $tbl)
{
$this->db->where('id', $id);
$r = $this->db->update($tbl, $data);
if($r)
return $r;
else
{
$r = $this->db->_error_message();
return $r;
}
}
My controller function code
public function upadteme()
{
$r = $this->ajax_model->updateItem($uid, $data, 'users');
echo $r." -- "; // Unable to get this echo working
//when using ajaxcall (calling controller through ajax) otherwise fine
}
It looks like the class will not populate _error_message if db_debug is on which it appears to be by default.
In config/database.php, set
$db['default']['db_debug'] = FALSE;
and try again.
