How to delete all user roles in Kohana 3 -

-

I'm using the ORM AUTH module and it's hard to understand how to do it. I have tried this matter: 

 $ user = ORM :: factory ('user', $ id); $ User-> roles-> delete_all ();

and error error exception [fatal error]: Call undefined method Database_Query_Builder_Delete :: join ()

However $ user-> ; Roles - & gt; Find_all (); gives me exactly what I need.

Instead of removing roles from the database, what you want to do, the relationships between the user model and the roles model Remove it You can use. 

  foreach ($ user- & gt; roles- & gt; find_all ($) as role) {$ user- & gt; Remove ('roles', $ roles); }

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
