In Yii1 I used to have my own components under the components folder of the structure, now with namespacing this is a little bit different.
I am new with name spaces, so for me was a little difficult to understand it at the beginning.
In this case I was extending DbManager for it to be compatible with the information that I had from Yii1.0 for the Authorization. I needed this to be working in the same database that I had my old application, as I fully upgrade it.
The following is the result of a question asked in the forum in the followin link : Wiki Post...
[*]Create the folder
I created my folder under the root directory and it is called components.
[*]Creating the namespace as the folde name.', ],
And that's it.
I hope that no one loose as much time as I did trying to do this.
