全球拒绝访问网站进行更新，Laravel

Question

This is a fairly open question as i am not sure what the best practice could/should be for this type of activity.

The scenario; A user based website (with logged in user areas and user editable content) needs to have several operations performed that will manipulate live data. To stop any errors occurring due to users simultaneously editing as the update is taking place, i need to shut out the users temporarily.

I don't currently have a config database table, just a config file. Two things need to happen;

• An update to the config happens to stop the users accessing certain areas of the website during the update - this is then reverted once the update is complete.
• The website (or at least portions on the site) need to be checked before every request for said portions of the site - so whatever the method, it needs to be lightweight

This is site built on Laravel.

Thanks!

I'll use serveral measures in this case.

1. put the code in try - catch block so that if something goes wrong, you can grcefully show an error message.

2. If there are mulitple executions invovled, then better use DB::transaction() and the system will roll back automatically if it encounters an error.

3. If you really want to put certain features on maintence mode, then put those routes in Route::group() and use a middleware for that group only. In that middleware, return response with 503 status. This way, you can put certain routes into maintanace mode while the rest will give 200 ok response.
