Laravel“字段列表”中的未知列“ _token”

Question

I've noticed strange behaviour over some Laravel apps.

When I run lets say

Users::where("id",$request->input("id"))->update($request->input());

Sometimes it goes through fine. In other cases I get

 Unknown column '_token' in 'field list'

So sometimes it only reads what is set in the $fillable parameter, and other times it takes everything from $request->input() . I keep comparing different models and see no difference. I know I can work around it by using the $request->only([]) method, but does anybody else have or had this issue and perhaps know a reason behind it?

Edit

This is my model.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class BookingRequests extends Model
{
    //
    protected $fillable = array(
        "account_id",
        "quote_id",
        "booking_id",
        "website_id",
        "color",
        "custom_group_name",
        "is_confirmed",
        "ready_to_issue",
        "created_by",
    );


    /**
     * Return Quote
     * @return \Illuminate\Database\Eloquent\Relations\BelongsTo
     */
    public function Quote(){
        return $this->belongsTo('App\Quotes',"quote_id","id");
    }
}

This is my controller

/**
     * Update Booking Reques
     * @param Request $request
     */
    public function update(Request $request){
        /**
         * Validate
         */
        $this->validate($request,array(
            "id" => "required"
        ));
        /**
         * Update
         */
        BookingRequests::where("id",$request->input("id"))->update($request->input());
        /**
         * Return
         */
        return redirect()->back()->with("success","Booking updated");
    }

This is being run on Laravel 5.3.31

Answer 1

To be honest what you are doing now is really risky. In fact it's possible now to update any fields no matter of $fillable property. This is because you are now updating like this:

Users::where("id",$request->input("id"))->update($request->input());

When you are making update like this in fact you are making update directly in database and Eloquent things are not used so the query that is executed looks something like this:

UPDATE users SET a=1, b=2 WHERE id = 5

so if anyone sends existing columns in this table they will be updated what is very very risky because you don't want anyone to modify columns you don't want to.

But if you do something like this:

$user = Users::where("id",$request->input("id"))->firstOrFail();
$user->update($request->input());

In above case Eloquent is used (first you find record in database and it's Eloquent model and then you try to update this Eloquent model), so now it's possible to update only fields that are in $fillable (assuming you are using 'fillable-way' but you do looking at your model). So now, no matter what is send in request, only fields in $fillable will be updated.

Obviously above could be written in a bit shorter way:

$user = Users::findOrFail($request->input("id"));
$user->update($request->all());

or even in one like like this:

Users::findOrFail($request->input("id"))->update($request->all());

Answer 2

You could use $request->except('_token'); By the way, check twice, that all data what could come by request is expected.

Answer 3

sometimes this error happens不会sometimes this error happens ， $fillable仅适用于批量分配，且创建/插入不在更新中，因此更新时，请包括_token列。
