## Installation

You can install `django-ffield` via pip:

```bash
pip install django-ffield
```

## Usage

### FileFField

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

#### Example:

```python
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'])
    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:

```python
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.

#### Example:

```python
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:

```python
from django_ffield.validators import FileTypeValidator

class MyModel(models.Model):
    file_field = models.FileField(upload_to='uploads/', validators=[
    FileTypeValidator(['image', 'pdf', 'mp4'])
    ])

# 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
```
