python - Django Imagekit overwrite cachefile_name? -


I am trying to overwrite the module django-imagekit to cachefile_name property.

Here's my code: 

  square thumb-150x150 (imageppeak): processor = [resizeToFill (150, 150)] format = 'JPEG' option = {'quality @: 90} @ property def cachefile_name (self): # Simplified for this example "bla / blub / test.jpg" register.generator ('blablub: thumb_150x150', thumb-150x150) class avatar (models.Model): avatar = ProcessedImageField (upload_to = upload_to, processor = [ConvertToRGBA ()], format = 'JPEG', option = {'quality': 60}) avatar_thumb = ImageSpecField (source = 'avatar', id = 'blablub: thumb_150x150') < / Code>  
 This does not work at all. 
 When I view the return value of debug (my  cachefile_name ), and the value of cachefile_name, the result is "CACHE / blablub / asdlkfjasd09fsaud0fj.jpg". Where's my fault  
 Any thoughts?   
 
 
 As an example I could have copied closely, it worked fine. Some suggestions are:  
 1) Make sure you are using avatar_thumb in a scene. The file "bla / blub / test.jpg" will not be generated until then.  
 2) To ensure that you are "bla / blub / test.jpg", check the configuration of your MEDIA_ROOT is expected to come.  
 Give me an example of something that I was working on. I wanted to give my thumbnail a unique name that can be guessed by the original file name. Imagekit's default scheme has thumbnails names based on hash, which I can not guess. Instead:  
  Media / 12345.jpg Media / CACHE / 12345 / abcde.jpg   
 I want to:  
 < Overriding IMAGEKIT_SPEC_CACHEFILE_NAMER did not work because I did not want to do all of my cached files "code / media / photos / original / 12345.jpg media / photos / thumb / 12345.jpg   
 Thumbs "directory, which arise from specific fields with a particular model.  
 So I created this ImageSpec subclass and registered it:  
  class Thumbnail Sips (Image Speak): Processor = [Thumbnail (200, 200, Anchor. CER , Crop = true, upscale = fail)] format = 'JPEG' option = {'quality': 90} "thumbnail" put in photo / thumb "folder and # name them as source file @property def cachefile_name (self) Only in: source_filename = getattr (self.source, 'name', none) = "photos / thumbs" / source_filename Returns register.generator ('Myapp: Thumbnail, thumbnail edge)   
 And then it was used in my model like this:  
  # Provide a unique name Each image file def EF get_file_path (example, filename): ext = filename.split ('.') [- 1] Return "% s.% S"% (uuid.uuid4 (), ext.lower ()) # (, Location = os.path.join (settings.MEDIA_ROOT, 'photos / original') base_url = '/ photos / original') 'photos / original' directory photoStorage = Store the original images in FileSystemStorage class photos (models.Model): Image = Models.ImageField (storage = photoStorage, upload_to = get_file_path) Thumb = ImageSpecField (source = 'image', id = 'MyApp: thumbnail')

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
