Modify request field value before saving in Laravel 5
提问by SomethingElse
I'm building app using laravel 5. I have such code:
我正在使用 laravel 5 构建应用程序。我有这样的代码：
public function store(ArticlesRequest $request, Pages $page)
{
$parentSlug = Pages::getParentSlug($request->parent_id);
$slug = ($request->slug)? $request->slug:$request->generic_title;
$validSlug = $request->makeSlug($slug);
$request->slug = $validSlug;
$page->create($request->all());
}
I want to update some data before saving, like slug, in this case , but it's not saving a slug field, if I directly don't input from form field. How can I update $request containing element values? For example $request->slug = $validSlug; and it save my edited slug in DB. Thank you very much!
我想在保存之前更新一些数据，例如 slug，在这种情况下，但它不会保存 slug 字段，如果我不直接从表单字段输入。如何更新包含元素值的 $request？例如 $request->slug = $validSlug; 并将我编辑的 slug 保存在数据库中。非常感谢！

You can manage request values like this:
您可以像这样管理请求值：
$request->offsetSet('slug', $validSlug);
However I agree with the comment above, it would be far better to manage a default value inside your Pages model.
但是我同意上面的评论，最好在 Pages 模型中管理一个默认值。
UPDATE:I previously had two methods, one of this no longer works as of Laravel 5.1 (thanks @omarjebary). Updated answer.
更新：我以前有两种方法，其中一种从 Laravel 5.1 开始不再有效（感谢 @omarjebary）。更新了答案。
