How do i programmatically create a model that has an imagefield and fields to capture width and height in Django -

-

मेरे पास एक फोटो मॉडल है जो इस तरह दिखता है 

  क्लास फोटो (models.Model) : title = models.CharField (MAX_LENGTH = 100, खाली = सच) चौड़ाई = models.IntegerField () ऊंचाई = models.IntegerField () छवि = models.ImageField (upload_to = upload_to_callable, width_field = "चौड़ाई", height_field = "ऊंचाई" ) content_type = models.ForeignKey (ContentType) object_id = models.PositiveIntegerField () content_object = generic.GenericForeignKey () create_date = models.DateTimeField (auto_now_add = सच) MODIFIED_DATE = models.DateTimeField (auto_now = सच) साइट = models.ForeignKey (साइट )   
 अपने एक परीक्षण में मुझे इस मॉडल को प्रोग्राम बनाने की आवश्यकता है I यह मैं क्या कर रहा हूँ है  
  डीईएफ़ _create_random_image (स्वयं): आयात छवि, ImageDraw img = Image.new ( "आरजीबी", (300,300), "#FFFFFF") आकर्षित = ImageDraw.Draw (आईएमजी) आर, जी, बी = प्रिंट (0,255), प्रिंट (0, 255), प्रिंट (0,255) डॉ = (प्रिंट (0, 255) -आर) / 300 डीजी = (प्रिंट (0, 255) - g) / 300 डीबी = (प्रिंट (0, 255) - बी) / 300 के लिए श्रेणी में (300): r, g, b = r + dr, g + dg, b + db draw.line ((i, 0, i, 300), भर = (int (r), int (g) ), पूर्णांक (ख))) tmpfilename = "/tmp/test36052.png" img.save (tmpfilename, "पीएनजी") च = फ़ाइल (tmpfilename) वापसी च डीईएफ़ testHomePageImage (स्वयं): tmpfile = self._create_random_image () तस्वीर = Photo.objects.create (छवि = tmpfile, title = site1_home_page.title, साइट = self.site1, content_object = site1_home_page)   
 मैं निम्न त्रुटि  
 AttributeError:? 'फ़ाइल' वस्तु वहाँ एक आंतरिक Django उद्देश्य यह है कि फ़ाइल उद्देश्य यह है कि मैं उपयोग कर सकते हैं प्रदान करता है कोई विशेषता 'चौड़ाई'  
 है   
 
 
 सीधे  f  की बजाय  ImageFile (f)  लौटने का प्रयास करें  ImageFile  में है  django.core.files.images.ImageFile । मेरे सिर के ऊपर से, मुझे लगता है कि ऐसा करेंगे।  
  संपादित करें: सही टाइपो, इसलिए यह सही है।

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
