Installation

You can install django-ffield via pip:

pip  install  django-ffield

Usage

FileFField

FileFField extends Django's FileField and allows you to specify accepted file types and disallowed types during field initialization.

Example:

from django.db import models

from django_ffield.fields import FileFField

  

class  MyModel(models.Model):

image_field = FileFField(upload_to='images/', types=['image'])

pdf_field = FileFField(upload_to='pdfs/', types=['pdf'],
					disallowed_types=['image','video'])

video_field = FileFField(upload_to='videos/', types=['video'])

  

# Usage

my_instance = MyModel.objects.get(pk=1)

my_instance.image_field = 'example.png'  # Validates as it matches the 'image' type

my_instance.pdf_field = 'example.pdf'  # Validates as it matches the 'pdf' type

my_instance.video_field = 'example.mp4'  # Validates as it matches the 'video' type

FiledFField

FiledFField is a field that extends Django's FieldFile and provides additional properties to access file-related information.

Example:

from django.db import models

from django_ffield.fields import FiledFField

  

class  MyModel(models.Model):

file_field = FiledFField(upload_to='uploads/')

  

# Usage

my_instance = MyModel.objects.get(pk=1)

file = my_instance.file_field

  

# Accessing file properties

mime_type = file.mime_type # Returns the mimetype (e.g., 'image/png')

file_type = file.type # Returns the type of file (e.g., 'Image')

file_format = file.format # Returns the file format (e.g., 'png')

Utility Functions

django-ffield provides a utility function for detecting file MIME types.

This function detects the MIME type of a file by reading the first 2048 bytes

note : the file should be opened in binary mode.

Example:

from django_ffield.utils import meme_type

from django.core.files import File

  

with  open('example.png', 'rb') as  file:

type, subtype = meme_type(file)

print(f"Type: {type}, Subtype: {subtype}")

Validators

django-ffield includes a custom file type validator that can be used with FileFField.

This validator ensures that the uploaded file's type is among the specified types.

Example:

from django_ffield.validators import FileTypeValidator

  

class  MyModel(models.Model):

file_field = models.FileField(upload_to='uploads/', validators=[

		FileTypeValidator(
		allowd_types=['image', 'pdf', 'mp4'],
		disallowed_types = ["audio"],
		)

])

  

# Usage

my_instance = MyModel.objects.get(pk=1)

my_instance.file_field = 'example.mp3'  # This will raise a ValidationError since 'mp3' is not in the accepted types
