REST API and null values in XML

Updated 26 days ago by marko60Tips0 comments – viewed 1,964 times – version 2.0
I have been working on a REST API using the excellent tools provided by Yii2. My problem was that I have to differentiate between empty values and null values. In other words, <elem></elem> is different from null as it represents an empty string. Also, although some use <elem/> to represent a null value it should still be interpreted as an empty string. In other cases, the absence of the element is taken to represent a null value, but this may create problem with some parsers.

Building a search GET request with scenarios ; calling a SearchModel from URLs...

Updated about a year ago by Louis GacTips0 comments – viewed 7,233 times – ( +1 ) – version 2.0
Search Models are a very elegant and powerful way to build an Active Data Provider. If you use them a lot, you'll quickly need to use scenarios, which will lead you to a very DRY Controller code.
