CNPJ and CPF Validation for Models
The code was placed inside a helper file without using a class. The Django validator was not designed to work with validator classes, it would appear, so retrieving the value from the field proved to be a hassle. Just create a helper file, import it on your model, and use the validator in the standard way, as such: cnpj = models.CharField(unique=True, max_length=14, validators=[validate_CNPJ]) cpf = models.CharField(unique=True, max_length=14, validators=[validate_CPF])

CSVField for forms
FileField that checks that the file is a valid CSV and if specified in `expected_fieldnames` checks that the fields match exactly. The widget's `accept` parameter is set to accept csv, text and excel files. **TODO**: Validate the entirety of the CSV file, not just the headers. But this should be enough for most use cases, as checking the whole file could be computationally expensive for huge files. Example usage: people = CSVField(expected_fieldnames=['First Name', 'Last Name'])

A streamable "export to CSV" admin action
This snippets is inspired from [#2995](https://djangosnippets.org/snippets/2995/) but add the following: * get rid of `singledispatch` so we can use it with python2 without pip installing anything * streaming capabilities * the configuration params (header, fields, exclude...) are passed to the action function so we don't pollute the ModelAdmin class * fix utf8 issue in header
