openerp - AttributeError: 'NoneType' object has no attribute 'get_default_company' -

  वर्ग बिक्री (osv.osv): _name = 'sale' _columns = {'name': fields.char ('कंपनी का नाम', आकार = 128)} def get_default_company (स्वयं, सीआर, यूआईडी, प्रसंग = कोई नहीं): कंपनी_आईडी = सेल्फ पॉयल.एट ('रिज। यूज़र')। ब्राउज़ करें (सीआर, यूआईडी, यूआईडी)। कॉम्पैनी_आईडी .id, return company_id बिक्री ()   
 मैं कोड के ऊपर प्रयोग किया है, सब ठीक है लेकिन मुझे नहीं पता कि मेरे फ़ंक्शन को कैसे और कैसे कॉल करें  get_default_company ()  । जैसा कि मैं इस पद्धति को कॉल करता हूं जैसे  
  cr और uid invalids    
 
 
 ऐसा लगता है कि आपको अपनी कंपनी के लिए डिफ़ॉल्ट मान सेट करने की आवश्यकता है इसके लिए आपको  _defaults  मॉडल विशेषता का उपयोग करना होगा जो आपके फ़ील्ड के लिए डिफ़ॉल्ट मान सेट करता है। जैसे  
  _defaults = {'company_id': get_company}   
 इस विधि से आपको get_company विधि को परिभाषित करने की आवश्यकता है जिसे कंपनी आईडी जैसे वापस करना चाहिए  
  def get_company (स्वयं, सीआर, यूआईडी, प्रसंग = कोई नहीं): user_rec = self.pool.get ('res.users')। ब्राउज़ करें (सीआर, यूआईडी, यूआईडी, प्रसंग) यूज़र_रेक कॉम। आईडी   
 और यह सब आपको  _columns  में एक फ़ील्ड की आवश्यकता है। इसलिए आपको  company_id  को  many2one  फ़ील्ड के रूप में जोड़ना होगा। जैसे  
  _columns = {'name': fields.char ('कंपनी का नाम', आकार = 128), 'company_id': fields.many2one ('res.company', "कंपनी") }   
 यह सब बदलें आपका मॉडल ऐसा दिखेगा,  
  वर्ग की बिक्री (osv.osv): _name = 'sale' _columns = {'name' ('कंपनी का नाम', आकार = 128), 'कंपनी_आईडी': फ़ील्ड्स। माईयाऑन ('रिस्क कॉपैनी', 'कंपनी')} डीईएफ़ get_company (स्वयं, सीआर, यूआईडी, प्रसंग = कोई नहीं): user_rec = ब्राउज़ करें (सीआर, यूआईडी, यूआईडी, प्रसंग) यूज़र_रेक कॉमप्यानी_आईडी.आईडी _डीफाल्ट = {'कम्पनी_आईडी': get_company} बिक्री ()    p> आशा यह मदद करता है!

python - Writing Greek in matplotlib labels, titles -

-
Image
I'm trying to write some text for labels, shape titles etc. with my plots, but no benefit till now Has not happened . I do not want to print specific characters (I know how to use special characters), I want to write the entire text in Greek (maybe Unicode and text ' ?). , suggesting that I would like to mention that for some reason I can not get matplotlib to cooperate with Tex (using IPython notebook from Anaconda in Ubuntu 14.10) so that there really is an option Will not be the first. I tried loading the Arial font and it loads successfully but again I get square blocks instead of characters. I import matplotlib.font_manager FM PROP = FM Font Properties (fname = '/ usr / share / fonts / truetype / msttcorefonts / Arial.ttf') And then to display the string I u'Î? ? I ?? Î¿Ï ??

Pygame memory leak with transform.flip -

-
Today I came across an interesting issue which, by writing a small side scroller, instead of a sprite sheet, I was planning to use because I lacked a good "packer" for making phantom sheets (and honestly with patience and passion as it is only a test project). Anyway, I showed the animation running on the right of 8 PNG (with transparency). I considered it a good idea to prepare the flipped images to run on the left in the consultant, and the frame is not framed when the game is running (Flip actually consumes a lot of CPU like I Was measured). > To get access to the loop, I get the memory leak self.move_l = [# 8 PNG images with transparency to the right] For the self in IMG. Move_l: self.move_r.append (pygame.transform.flip (img, true, false) error traceback: traceback (most recent Call final): The file "D: \ Python 34 \ _Projects \ efg \ efg.py", in line 196, in the & lt; module & gt; main = master program ((1024, 680)) "D: \ Python ...

cmake set_source_files_properties not working properly -

-
I have a project in which. C is a group of files which need to be compiled as C files, but I need it to be compiled as C ++ code. I tried the solution I found, but did not work as expected. Instead of making filename.c only, it is compiled as C ++, it compiles all the files in my project as C ++ code. Without that call, all the files have been compiled as C. I also tried: set_source_files_properties ($ {FILES_SRC} property languages ​​C) set_source_files_properties (filename.c property languages ​​CFX) Where FILES_SRC variable keeps all my source files. I am CMK 2.8.12 and Visual Studio 11 ARM Generator. Any ideas how can I fix this? I finished compiling the library using C compiler and added a C ++ code to a different library For which I created a C interface so it can be told from my C library.
