A simple way to incorporate Cloudinary into Django is by using Django Cloudinary Storage, a Django package designed to streamline the integration process with Cloudinary. This package leverages the Django Storage API to seamlessly connect your Django application with Cloudinary. By configuring just a few lines of code, you can begin utilizing Cloudinary for both your media and static files. Additionally, this package offers convenient management commands to effortlessly remove any unwanted files, making cleanup a hassle-free task. Behind the scenes, Django Cloudinary Storage relies on the pycloudinary package to handle the Cloudinary functionality.

To gain enhanced control, you have the option to utilize a Python library. If you are working with Django, you can seamlessly incorporate Cloudinary's uploading functionalities into your forms and models by leveraging Cloudinary's helper classes. For instance, you can define a model class called "Photo" in your models.py file, as demonstrated in the example below. This "Photo" class includes an image field of the CloudinaryField class, enabling smooth integration with Cloudinary's features.

Example upload and usage with storage
The storage functionality operates seamlessly and transparently. Once your server is properly configured, you can effortlessly utilize the ImageField in your code and seamlessly upload your files to Cloudinary.
logo = models.ImageField(upload_to="logo/", verbose_name="logo", max_length=250, blank=True, null=True)
If you find yourself needing to frequently download and upload images from a specific location to Cloudinary, you can accomplish this task using the following approach.
To save an image from a URL using Django's `ImageField`, you can follow these steps:
def save_image_from_url(self, url):
home_images = "/home/tmp/images/"
response = requests.get(url)
if response.status_code != requests.codes.ok:
return None
file_name = urlparse(url).path.split("/")[-1]
path_to_file = home_images + file_name
with open(path_to_file, 'wb') as temp_file:
temp_file.write(response.content)
reopen = open(path_to_file, "rb")
django_file = File(reopen, name=file_name)
return django_file
Troubleshooting
1.
ImportError at /vehicles/vehicleimage/154/change/Module "cloudinary_storage.storage" does not define a "MediaCloudinaryStorage" attribute/class
Request Method: GET
Request URL: https://stock.autov.be/vehicles/vehicleimage/154/change/
Django Version: 4.1.6
Exception Type: ImportError
Exception Value: Module "cloudinary_storage.storage" does not define a "MediaCloudinaryStorage" attribute/class
Exception Location: /usr/local/lib/python3.8/dist-packages/django/utils/module_loading.py, line 32, in import_string
Raised during: django.contrib.admin.options.change_view
Python Executable: /usr/bin/python3
Python Version: 3.8.10
I fixed this problem with upgrade
sudo apt remove python3-pip
wget https://bootstrap.pypa.io/get-pip.py
sudo python3 get-pip.py
sudo pip3 install pyopenssl --upgrade
2.
The code from stackoverflow or ChatGPt will not work. We getting Empty file error from cloudinary when we try to save it via django.
So, i see file in momory i can save it but cloudinary return
Then if you try to save
result = cloudinary.uploader.upload(url)
You will get configuration error, because configuration of storage is not the same and you have to configure it separately. I do not want that.
1. Install the `Pillow` library, if you haven't already, by running `pip install Pillow` in your terminal or command prompt.
2. Import the necessary modules in your Django project's file where you want to handle the image saving.
```python
from django.core.files import File
from django.core.files.temp import NamedTemporaryFile
import requests
from urllib.parse import urlparse
from urllib.request import urlopen
```
3. Define a function that will download the image from the URL and return a `File` object.
```python
def save_image_from_url(url):
request = requests.get(url, stream=True)
if request.status_code != requests.codes.ok:
return None
file_name = urlparse(url).path.split("/")[-1]
temp_file = NamedTemporaryFile(delete=True)
temp_file.write(request.content)
temp_file.flush()
return File(temp_file, name=file_name)
```
4. In your Django model, use the `ImageField` to store the image:
```python
from django.db import models
class YourModel(models.Model):
image = models.ImageField(upload_to='your_upload_directory/')
```
5. When you want to save an image from a URL, call the `save_image_from_url` function and assign the returned `File` object to the `image` field of your model instance. Then save the model instance.
```python
your_model_instance = YourModel()
image_url = 'https://example.com/image.jpg'
image_file = save_image_from_url(image_url)
if image_file:
your_model_instance.image.save(image_file.name, image_file, save=True)
your_model_instance.save()
```
In the code above, replace `'your_upload_directory/'` with the desired directory where you want to store the uploaded images. Make sure the directory exists within your Django project's `MEDIA_ROOT`.
Remember to configure your Django project's settings correctly to handle media files. You need to set the `MEDIA_ROOT` and `MEDIA_URL` in your settings file, and include the necessary URL patterns for serving media files in your project's URLs configuration.
Once Cloudinary is properly configured, it will automatically handle the uploading process.
