Why doesn't rails clear (a cached) belongs_to value when setting the _id value? -

-

रेल का उपयोग करना, पर विचार करें: 

  & gt; पी = पोस्ट.न्यू & gt; P.author = person.find (1) & gt; P.author_id = 99 & gt; P.author_id = & gt; 99 & gt; पी। लेखक = & gt; # & Lt; व्यक्ति आईडी: 1, नाम: "व्यक्ति 1" & gt;

जो मैंने कभी नहीं समझा है: क्या कोई सचेत निर्णय सीक है? क्या कुछ प्रकार के एक प्लगइन है जो इसे ठीक करता है?

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.

This will allow dragon to search your modules (otherwise, Python looks for the .py module).
