Upload files in Yii2 with MongoDb and GridFs

Updated 3 years ago by skwordenHow-tos3 comments – viewed 19,503 times – ( +8 / -1 ) – version 2.0
Uploading files in a webapp can be extremely tricky and sometimes the quickest way to do it is to store the file directly in the webserver or into a DNS (like Amazon S3) and then to save the link and the metadata inside a table in the DB. The thing is that you'll have to deal with file permissions, server storage, file management and so on (which is perfectly fine, by the way).

Yii configuration: Dynamic & User dependent

Updated 3 years ago by le_topHow-tos0 comments – viewed 6,333 times – ( +1 / -1 ) – version 1.1
It is difficult to perform user dependent theming through a general configuration in 'main.php'. This article proposes a method to do so through a Factory that dynamically generates classes to allow delayed resolution of actual user values. This means that you can refer to values that are stored in the database through the CActiveRecord before Yii is actually loaded. The values will be fetched from the database when actually used for the first time, which is after Yii is loaded. Actually, you can use pretty much any method that relies on Yii with this method.
