Question

我有一个FormRequest，我想在更新行时验证字段fiscal_id的唯一性，这是一种验证工作，但是问题是fiscal_id可能为空，因此如果在更新时我发送null，则唯一规则不会通过。

'fiscal_id' => [
    'sometimes', 
    Rule::unique('table', 'fiscal_id')->where(function($query) {
        $query->whereNull('deleted_at')
            ->where('company_id', auth()->user()->company_id);
    })->ignore($this->route('customer')->id)
]

当fiscal_id null时，如何验证null的唯一性（因为--Sample data CREATE TABLE #Login(ID INT IDENTITY, PW nvarchar(20)); INSERT INTO #Login (PW) VALUES ('n9$%^Usj4jjr'), ('Nehj47$%^$'), ('MNAtokay543^A36#$^#%'), ('(*&^#$^dfh$%&'), ('$%^h345nfs54y'); SELECT l.ID, SpecialChars = COUNT(*) FROM #Login AS l CROSS APPLY dbo.NGrams8k(l.PW,1) AS ng WHERE PATINDEX('[^a-zA-Z0-9]',ng.token) = 1 GROUP BY l.ID HAVING COUNT(*) > 5;还有其他字段，所以它失败了。）

尝试像这样单独验证创建和更新

public function rules() {
    // rules for updating record
    if ($this->method() == 'PATCH') {
        return [
            'fiscal_id' => [
                 'nullable',
                 Rule::unique('table', 'fiscal_id')->where(function($query) {
                    $query->whereNull('deleted_at')
                 ->where('company_id',auth()->user()->company_id);
                 })->ignore($this->route('customer')->id)
             ]
        ];
    } else {
    // rules for creating record
        return [
            'fiscal_id' => [
                 'required',
                 Rule::unique('table', 'fiscal_id')->where(function($query) {
                    $query->whereNull('deleted_at')
                 ->where('company_id',auth()->user()->company_id);
                 })
             ]
        ];
    }

}

唯一规则，忽略空值
