eloquent

问题 Im using laravel for a project i am wanting to create an endpoint which filters and searches a Film model and returns a collection of films that match the chosen filter options which will be Options, Location and Age Rating picked by the user.

问题 I am moving an application from my development machine to a test server. When connecting to my local development mysql database everything works as expected. When attempting to connect to our test server, the requests time out after 45 seconds and a 500 error is returned. I tested that the servers can communicate and php can get results by using the basic mysqli php functionality, and results are returned as expected: // Create connection $conn = new mysqli($servername, $username, $password,

问题 I have SQL query (see example). But I can't find a way how I can write it in Query Builder. Do you have any ideas how is it possible?
