1. In Laravel 6, execute the UpdateOrCreate method to update the existing model or create a new model if it does not exist. The last generated sql is as follows, the field checksum is missing. as shown in Figure 1
insert into
`table` (
`asset_key`,
`theme_id`,
`mime_type`,
`created_at`,
`updated_at`,
`content`,
`schema`,
`category`
)
values
(
'apps/internal/back-top/app.json',
'989925b6-58d3-4fee-a50f-8cd084462bf6',
'application/json',
'2023-03-03 09:21:47',
'2023-03-03 09:21:47',
'{\n \"title\": \"回到顶部\",\n \"description\": \"为页面增加返回到页面顶部的按钮，提高用户体验。\"\n}\n',
null,
'unknown'
)
2. The code is implemented as follows:
$predicate = [
'asset_key' => $to.$view['asset_key'],
'theme_id' => $themeId,
];
$extra = [
'mime_type' => $view['mime_type'],
'created_at' => $view['modified_at'],
'updated_at' => $view['modified_at'],
'content' => $content,
'schema' => $schema,
'checksum' => $checksum,
'category' => $category
];
ThemeAsset::updateOrCreate(
$predicate,
$extra
);
3. Print the variable $extra, and determine that the field checksum is not null, which means that the field checksum is omitted in the sql statement because its value is null. as shown in Figure 2
array(7) {
["mime_type"]=>
string(16) "application/json"
["created_at"]=>
object(Illuminate\Support\Carbon)#6487 (19) {
["endOfTime":protected]=>
bool(false)

string(8) "timezone"
}
["dumpLocale":protected]=>
NULL

string(3) "UTC"
}
["updated_at"]=>

bool(false)

bool(false)

}
["content"]=>
string(120) "{
"title": "回到顶部",
"description": "为页面增加返回到页面顶部的按钮，提高用户体验。"
}
"
["schema"]=>
NULL
["checksum"]=>
string(40) "2a0fe2215b02b5738926ff93cde566d43ad8188e"
["category"]=>
string(7) "unknown"
}
4. Edit the model and add checksum to the $fillable property. The last generated SQL is as expected, and the value of the field checksum has been inserted. as shown in Figure 3
protected $fillable = [
'asset_key',
'theme_id',
'content',
'mime_type',
'created_at',
'updated_at',
'category',
'checksum',
'schema'
];
insert into
`table` (
`asset_key`,
`theme_id`,
`mime_type`,
`created_at`,
`updated_at`,
`content`,
`schema`,
`checksum`,
`category`
)
values
(
'apps/internal/back-top/app.json',
'989931f5-7e35-4943-b11d-00a0b900626c',
'application/json',
'2023-03-03 09:56:07',
'2023-03-03 09:56:07',
'{\n \"title\": \"回到顶部\",\n \"description\": \"为页面增加返回到页面顶部的按钮，提高用户体验。\"\n}\n',
null,
'2a0fe2215b02b5738926ff93cde566d43ad8188e',
'unknown'
)
