Fields:
----------------


## Base64ImageField

An image representation for Base64ImageField

Intherited by `ImageField`


**Signature:** `Base64ImageField()`

- It takes a base64 image as a string.
- a base64 image: `data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7`
- Base64ImageField accepts the entire string or just the part after base64, `R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7`
- It takes the optional parameter represent_in_base64(False by default), if set to True it wil allow for base64-encoded downloads of an ImageField.
- You can inherit the Base64ImageField class and set allowed extensions (ALLOWED_TYPES list), or customize the validation messages (INVALID_FILE_MESSAGE, INVALID_TYPE_MESSAGE)


**Example:**

```python
# serializer

from drf_extra_fields.fields import Base64ImageField

class UploadedBase64ImageSerializer(serializers.Serializer):
file = Base64ImageField(required=False)
created = serializers.DateTimeField()

# use the serializer
file = 'R0lGODlhAQABAIAAAP///////yH5BAEKAAEALAAAAAABAAEAAAICTAEAOw=='
serializer = UploadedBase64ImageSerializer(data={'created': now, 'file': file})
```


## Base64FileField

An file representation for Base64FileField

Intherited by `FileField`


**Signature:** `Base64FileField()`

- It takes a base64 file as a string.
- Other options like for Base64ImageField
- You have to provide your own full implementation of this class. You have to implement file validation in `get_file_extension` method and set `ALLOWED_TYPES` list.


**Example:**

```python
class PDFBase64File(Base64FileField):
ALLOWED_TYPES = ['pdf']

def get_file_extension(self, filename, decoded_file):
try:
PyPDF2.PdfFileReader(io.BytesIO(decoded_file))
except PyPDF2.utils.PdfReadError as e:
logger.warning(e)
else:
return 'pdf'
```


## PointField

Point field for GeoDjango


**Signature:** `PointField()`

- It takes a dictionary contains latitude and longitude keys like below

{
"latitude": 49.8782482189424,
"longitude": 24.452545489
}

**Example:**

```python
# serializer

from drf_extra_fields.geo_fields import PointField

class PointFieldSerializer(serializers.Serializer):
point = PointField(required=False)
created = serializers.DateTimeField()

# use the serializer
point = {
"latitude": 49.8782482189424,
"longitude": 24.452545489
}
serializer = PointFieldSerializer(data={'created': now, 'point': point})
```

## IntegerRangeField

```python
from rest_framework import serializers
from drf_extra_fields.fields import IntegerRangeField


class RangeSerizalizer(serializers.Serializer):
ranges = IntegerRangeField()


serializer = RangeSerizalizer(data={'ranges': {'upper': 0, 'upper': 1}})

```

## FloatRangeField

```python
from rest_framework import serializers
from drf_extra_fields.fields import FloatRangeField


class RangeSerizalizer(serializers.Serializer):
ranges = FloatRangeField()


serializer = IntegerRangeSerizalizer(data={'ranges': {'upper': 0., 'upper': 1.}})

```

## DateRangeField

```python
import datetime

from rest_framework import serializers
from drf_extra_fields.fields import DateRangeField


class RangeSerizalizer(serializers.Serializer):
ranges = DateRangeField()


serializer = RangeSerizalizer(data={'ranges': {'upper': datetime.date(2015, 1, 1), 'upper': datetime.date(2015, 2, 1)}})

```

## DateTimeRangeField

```python
import datetime

from rest_framework import serializers
from drf_extra_fields.fields import DateTimeRangeField


class RangeSerizalizer(serializers.Serializer):
ranges = DateTimeRangeField()


serializer = RangeSerizalizer(data={'ranges': {'upper': datetime.datetime(2015, 1, 1, 0), 'upper': datetime.datetime(2015, 2, 1, 0)}})

```

CONTRIBUTION
=================

**TESTS**
- Make sure that you add the test for contributed field to test/test_fields.py
and run with command before sending a pull request:

```bash
$ pip install tox # if not already installed
$ tox -e py27
```

Or, if you prefer using Docker (interactively):

```bash
docker pull lambdacomplete/drf-extra-fields
docker run -i -t lambdacomplete/drf-extra-fields /bin/bash
$ tox -e py27
```

To build the image yourself and run the tests automatically:
```bash
docker build -t ${MY_IMAGE} .
docker run ${MY_IMAGE}
```

*Note:* mounting the working directory via `-v` prevents tox from running (tox uses hard links which do not work with mounted directories). We are still working on this.

**README**
- Make sure that you add the documentation for the field added to README.md
