我正在构建一个活动记录器，而不是需要尽可能细化。一个例子是用户可以更新一些项目细节，
project = Project::find($id);
//die(print_r(Input::all()));
$project->name = Input::get('name');
$project->description = Input::get('description');
$project->total_cost = Input::get('cost');
$project->start_date = Input::get('start_date');
$project->finish_date = Input::get('end_date');
$project->run_number_days = $this->get_days_between_two_dates(Input::get('start_date'), Input::get('end_date'));
$project->num_days_from_year_start = $this->get_days_between_two_dates("2014-01-01", Input::get('start_date'));
//$project->color = $this->project_rbg_to_project_hex();
$project->organisation_id = Input::get('organisation_id');
$project->sales_person = Input::get('sales_person');
$project->project_manager = Input::get('project_manager');
$project->user_id = ResourceServer::getOwnerId();
$project->client_id = Input::get('client_id');
$project->save();

现在有时在更新中只有一个字段实际上已经更改了内容，是否可以返回哪些字段有新内容？有没有比我现在更好的更新方式？
答案 0 :(得分：1)
尝试将数据库行与array_diff()
$affectedColumns = array_diff($project->toArray(), Input::all());
Input返回的内容超过了所比较的内容，请使用Input::only() 指定要比较的内容
$compareIndexes = array('id','name','description','total_cost','start_date','finish_date','run_number_days','num_days_from_year_start','color','sales_person','project_manager','client_id','organisation_id','user_id','created_at','updated_at');
$affectedColumns = array_diff($project->toArray(), Input::only($compareIndexes ));
或者，使用$project->getFillable()检索模型的可填写键。
$affectedColumns = array_diff($project->toArray(), Input::only($project->getFillable()));
