Django soft resize uploaded Image to multiple sizes and upload to respective folder
I have the following model on my App def image_path(self, filename): return 'app_name/images/{}/{}'.format(slugify(self.name), filename) class Color(models.Model): name = CICharField(max_length=22, unique=True) image = models.ImageField("Image", upload_to=image_path, blank=True) Once the image is uploaded I want to create 3 images size: small (100 by 100), medium (300 by 300) and large (800 by 800) with the soft image crop. Then I want to manage the URL Structure for my upload. For Eg. Original Image URL from "Image" field = 'app_name/images/image_1.jpg' if I upload the image, Then it will produce the following images. small = 'app_name/images/small/image_1.jpg' medium = 'app_name/images/medium/image_1.jpg' large = 'app_name/images/large/image_1.jpg' Can anyone tell me, How can I achieve this on Django. Thanks. -
How do I consume data from Django Rest Framework API with frontend javascript (separate repository)
I can view my api with the Browsable API and I can make calls to my DRF API using postman, but I can't seem to integrate with a frontend. The same goes whether it is deployed or local. These are the headers from the response in Postman: Date →Sat, 05 Sep 2020 23:29:15 GMT Server →WSGIServer/0.2 CPython/3.8.5 Content-Type →application/json Vary →Accept, Cookie Allow →GET, HEAD, OPTIONS X-Frame-Options →DENY Content-Length →185 X-Content-Type-Options →nosniff Referrer-Policy →same-origin These are some of the settings I have implemented for my DRF API settings: ALLOWED_HOSTS = ['*'] REST_FRAMEWORK = { 'DEFAULT_PERMISSION_CLASSES': [ 'rest_framework.permissions.AllowAny' ], 'DEFAULT_FILTER_BACKENDS': ['django_filters.rest_framework.DjangoFilterBackend'], } MIDDLEWARE_CLASSES = ( 'corsheaders.middleware.CorsMiddleware', 'django.middleware.common.CommonMiddleware', ) CORS_ORIGIN_ALLOW_ALL=True Here's a call that I'm attempting to make from my local react project which returns empty: const [data, setData] = useState(); useEffect(async () => { const result = await axios.get( 'http://127.0.0.1:8000/movies/1', { headers: { 'Content-Type': 'application/json' } } ); setData(result); }, []); I've attempted to consume the data with local and remote JS frontends to no avail. -
How to check if value from a field in a table object is equal to specific string in django template language?
I am iterating over all the entries in a django table called Ideas. One field in the table is status, and I want to check if the status is equal to some specific string. I have already checked that I am accessing this field correctly, with idea.status in my case, but I can't find how to compare that entry to a specific string in the django template language docs. I am trying to change a table's cell color based on what is in that cell. Here is what I tried, but to no avail: {% for idea in ideas_list %} ... {% if idea.status == 'Not Started' %} <td style="background-color:red;"> {% elif idea.status == 'Completed' %} <td style="background-color:green;"> {% elif idea.status == 'In Progress' %} <td style="background-color:yellow;"> {% else %} <td> {% endif %} {{idea.status}} &nbsp;</td> ... {% endfor %} My page is still rendering with the status text in the table, suggesting to me that all the if's were failed, which would end in the else condition being met, giving <td>{{idea.status}} &nbsp;</td>, with no cell color, and suggesting to me the problem is in my if statements themselves. -

Django API: Revoke tokens after a certain amount of request

I use token authentication for the ease of use, however, I don't understand/can't imagine how I can limit the amount of requests a user can make on a per month basis.

How to convert an object in django rest framework to a hyperlink

Unexpected format when passing a DateField straight to a template
I have a DateField on my model. And I'm passing the fields value straight into a DocxTemplate, where it comes out as "YYYY-mm-dd" format.

In "models.py": class Bar(models.Model): date_fld = models.DateField() Generating the "docx": from app.models import Bar from django.shortcuts import get_object_or_404 from docxtpl import DocxTemplate ... bar = get_object_or_404(Bar, pk=1) tpl = DocxTemplate("tpl.docx") context = { 'foo': bar.date_fld, } tpl.render(context) tpl.save("result.docx") I know that I could use a function to convert the date to a string, but it doesn't seem like a Django way of doing things: def getDateString(date): return date.strftime('%d/%m/%Y') And then: context = { 'foo': getDateString(bar.date_fld), } -

How to communicate from a webserver to a local device using UDP?
Here's the scenario: I have a webserver(django) hosted on the cloud, which needs to send some data to an android application (also developed by me) when some event occurs. I don't want to use polling using Http or other protocols from the android. What i want is the webserver to send the data via UDP (socket programming on both android and django). I have tested this by hosting the webserver on my local computer and providing the local IP of the android devices. It works perfectly. The scenario changes when the same server is hosted on the cloud as now, I don't know the public IP of the Android devices. WhatismyIp on google simply shows the public IP of the router which is not enough to route the packets to my local devices. Using a VPN and its managed IP works ofcourse, but is there a way to do this without a VPN? Any help will be appreciated. -

CKEditor deleting <span> in Django
I'm having a problem with CKeditor (with ckeditor_uploader) in Django, I looked everywhere, found a lot of answers but none of those worked.

Facebook Link Sharing Issue
I have a single "share to facebook" link on my site using Django Social Share. The issue is that the link being posted to Facebook isn't being scraped - the image, the description, and the title are not populating. All OG meta tags are present and correct, so I checked the Facebook Sharing Debugger and it shows the following error: SSL Error Can't validate SSL Certificate. Either it is self-signed (which will cause browser warnings) or it is invalid. Curl Error Curl error: 60 (SSL_CACERT) The site's SSL cert is perfectly valid - no errors or warnings at all. I'm using LetsEncrypt on Apache with a Django app behind it through WSGI. No issues with any other social networks. An example of one of the links giving this error: https://www.netizen.net/news/post/2643/netizen-ranks-184-on-the-2020-inc-5000-list As you can see if you visit the page, there are no SSL errors. The same link is scraped just as expected on LinkedIn, Twitter, and elsewhere but FB seems to have this issue. -
