@cache(60) def heavy_computation(): for x in xrange(10000000): pass # just waste some time` The result of `heavy_computation` calls will be cached for 60 seconds. This cache decorator does not use the Django cache backend and uses the local memory instead.
This Base64Field class can be used as an alternative to a BlobField, which is not supported by Django out of the box. The base64 encoded data can be accessed by appending _base64 to the field name. This is especially handy when using this field for sending eMails with attachment which need to be base64 encoded anyways. **Example use:** class Foo(models.Model): data = Base64Field() foo = Foo() foo.data = 'Hello world!' print foo.data # will 'Hello world!' print foo.data_base64 # will print 'SGVsbG8gd29ybGQh\n'
This is possibly the simplest solution for storing binary data in a TextField.
I tend to have all my python code together in a 'python' directory. e.g. a typical project layout of mine looks like: /python /python/myproject - project python code /python/django - local copy of django /python/foolib - some third party library /media /templates ... Since I don't want to set the python path explicitly I just assume the 'manage.py' is in the right place and use its __file__ variable to set up the python path correctly. I use the same trick for my settings.py for setting MEDIA_ROOT and TEMPLATE_DIRS.
I wanted to mark rows with an erroneous input with 'class="error"' and move the errorlist below the input tag so I wrote a NormalRowFormatter which behaves like a format string by overwriting \_\_mod\_\_. Examples: class MyForm(PrettyBaseForm, forms.Form): # add your fields here SomethingForm = form_for_model(Something, form=PrettyBaseForm)
This snippet provides a form_for_model and form_for_instance function which create newforms that respect the unique and unique_together constraints defined in the model. One thing about the coding style in this code snippet: Classes are capitalized even if they're passed as arguments. Thus "Model" is a model class while "model" is a model instance.
