如何在更新表中的列之前创建一个触发器，将整个旧行保存到新表中？

Question

I have the team_members table, with the following structure, where only project_request_id gets updated. I created log_team_members with the same data structure, so whenever I update team_members I lose the old data, which I need for reads, that's why I was thinking of creating a trigger that before updating team_members project_request_id , it saves the entire old row to this table.

Can you help me to build this trigger from a Latavel migration?

public function up()
{
    Schema::create('team_members', function (Blueprint $table) {
        $table->increments('id');
        $table->string('name');
        $table->string('title');
        $table->string('picture');
        $table->string('email')->unique();
        $table->string('phone_number');
        $table->text('background_information')->nullable();
        $table->timestamps();
        $table->integer('project_request_id')->unsigned();
        $table->foreign('project_request_id')->references('id')->on('project_requests')->onDelete('cascade');
    });
}

public function up()
{
    Schema::create('team_members', function (Blueprint $table) {
        $table->increments('id');
        $table->string('name');
        $table->string('title');
        $table->string('picture');
        $table->string('email')->unique();
        $table->string('phone_number');
        $table->text('background_information')->nullable();
        $table->timestamps();
        $table->integer('project_request_id')->unsigned();
        $table->foreign('project_request_id')->references('id')->on('project_requests')->onDelete('cascade');
    });
}

And this where the team_members update happens:

public function createProjectTeam(Request $request){
            try {
                $projectRequest = 
ProjectRequest::create(['project_title' => $request->projectTitle, 
'client_id' => $request->projectClientId]);

                TeamMember::whereIn('email', $request->projectTeamEmails)
                ->update([
                    'project_request_id' => $projectRequest->id 
                ]);

                $projectTeam = TeamMember::where('project_request_id', $projectRequest->id)->get();

            return response()->json( [
                'success'=> true,
                'projectRequest' => $projectRequest,
                'projectTeam' => $projectTeam,
            ]);

            } catch(\Exception $e){
                return ['success' => false, 'message' => 'project team creation failed'];
            }

        }

// use DB; 
$data = UpdateModelName::find(1);
$copy = $data->replicate()->toArray();
// store data in new table
$newTable = new NewTableModel;
$newTable->insert($copy);
