Eloquent Mutators allows us to define accessors and mutators outside of an Eloquent model. This gives us the ability to organize and reuse them on any model or any attribute of the same model.

Hello I'm getting the following error
PDOException: SQLSTATE[22007]: 1292 Incorrect datetime value '2022-03-07T18:08:12.000000Z' for column 'created_timestamp' at row 1 in /[path]/[to]/[project]/vendor/laravel/framework.src.Illuminate/Database/Connection.php:496

QUESTION
... You are strongly encouraged to always use this serialization format, as well as to store your application's dates in the UTC timezone by not changing your application's timezone configuration option from its default UTC value. ...
I'm confused, how/when am I supposed to change the timezone of the dates ? I know that if I pass a UTC date to javascript it would be converted to the user's timezone (with new Date(), right ?) but what if I'm gonna show the data directly to the user without going through javasacript ? (like a blade page, generating a pdf ...), how can I make sure that the timezone will be the same across the application? I know Carbon can be used to convert dates timezone but I don't want to manually do the conversion everytime, should I like add a custom configuration variable or is there a better way to do it ?
...ANSWER
Answered 2021-Dec-02 at 07:28Timezone should be changed when:
- To user timezone: when you present the date
- To UTC: when you get the date from the user input
I personally use macros for this

how to save the data from the Features fields on a different table. Example in the link below, it is saving the Features table fields in a JSON field in the database. However, I want to save this data from the features into another table.

I'm coming back here to post my answer. I managed to settle, I'm putting here to help other developers.
This first part of the question I have already solved. But now I can not bring the data from the Features fields in the form.
Below is the source code that I was able to save and edit the form data. However, I can not carry the data from the Feature fields. Someone knows how I can carry the field data in Feature
...ANSWER
Answered 2021-Jun-13 at 17:37There are a few ways to go about it. Personally I prefer to create accessors and mutators in the model - https://laravel.com/docs/8.x/eloquent-mutators . Not only does it keep the CrudController clean (so updateable) but it also allows you to save/load stuff from other forms (ex: user-facing forms).
QUESTION
I have a field in my database that stores a decimal value. It's defined in my database migration as such:
ANSWER
Answered 2021-Jan-15 at 21:19This happens because PHP doesn't have a decimal type, so the value is converted to a string (see this Laracasts post)
When casting to a decimal, the asDecimal(...) function in Illuminate\Database\Eloquent\Concerns\HasAttributes is called; this function uses the native PHP function number_format, which returns a string.
QUESTION
I am not sure I fully understand Laravel Eloquent attribute casting. According to documentation, (https://laravel.com/docs/8.x/eloquent-mutators#attribute-casting), these are the supported types:
integer, real, float, double, decimal:, string, boolean, object, array, collection, date, datetime, timestamp, encrypted, encrypted:object, encrypted:array, and encrypted:collection
So far, I've only used date casting on my models (when the fields were stored as timestamps in the db), like this:
...ANSWER
Answered 2020-Oct-30 at 16:59By default, attributes will be casted to the type of column defined in the table. So, if your column is an integer, then it will be casted as int.
But, what happens if you want to modify this behavior for specific fields? That's when attribute casting enters the scene.
For example, imagine we have in a table called projects a column named config of type json in which we can store additional configuration elements for each project.
In my case, it'd be useful to be able to handle this data as an array. So, instead of receiving a string or object, we can just deal with a simple array. To do this, we just:
QUESTION
I have a Laravel 7 project with the need of a lot of data transformation from the model to the views before being displayed.
I thought about using Laravel Accessors and use them directly in my blade.php files.
But when I finished dealing with a simple html table, I looked at my code and I think there is too many accessors and even some of them have a difficult name to read.
ANSWER
Answered 2020-May-12 at 06:22I have 2 solutions for this case which ive tested on my local machine. Though am not sure if they comply with the best practices or design principles, that has to be seen, but i am sure that they will organize the code in a managable way.
First is you can create an accessor that is an array and club all your logic inside it which will compute and return the array. This can work for 4-5 attributes maybe, and you will have to make changes to your views to access the array instead of the properties. Code example 1 is given below
Second way is to create a separate class which will house all the different computing logic as methods. Lets say you make a ModelAccessor class, you can then create accessors in your Model class just the way you are doing now and return ModelAccessor->someMethod from inside each of them. This will add some neatness to your Model class and you can manage your computation logic from the class methods easily. Example code 2 below may make it more clear
- Example 1 for arrays as accessors
Lets call the returned attribute
$stats

I'm writing a REST API using Lumen. I have for my example 2 models User and Post. Post model use the method belongsTo to get the User model which created this post. My goal was to define an accessor so I can get the author's username of the post just like that Post::find($id)->author. So according to the doc I do this:

...ANSWER
Answered 2020-May-11 at 12:21This behavior is because of performance. When you call
$post->userfor first time, The Laravel read it from the database and keep it in$post->relation[]for next usage. So next time Laravel can read it from the array and prevent from executing a query again(it will be useful if you use it in multiple places).Plus, the user is also an attribute and the Laravel merges
$attributesand$relationsarray together when you call$model->toJson()or$model->toArray()
