cant get profile images to display with django
I am working through a basic django upload image tutorial and I have become stuck. I am trying to let a user upload a file, store it in in a folder, and then save the address to that image in the db. This part all seems to be working. Then I try and have a simple page to display all images to make sure its working and the img tag in the HTML keeps having a src of "unknown". I am unsure of what exactly the problem is because there are no errors thrown anywhere.

How to copy the data in old col to new col with only unique values?
I'm trying to create a new unique field called last_name_unique. I need to copy the data from last_name to last_name_unique. The new field can be nullable so we can add null for the repeated values. For example, if there are two last names with value "Junior", under the last_name_unique there will be one value "Junior" and then null for the other "Junior" value. from django.db import models class Person(models.Model): first_name = models.CharField(max_length=30) last_name = models.CharField(max_length=30) Any idea how to achieve this would be appreciated. -
Django - How to set ordering on ManyToMany field queryset
I have following models: class Hashtag(models.Model): ... created = models.DateTimeField(auto_now_add=True) ... class Tweet(models.Model): ... hashtags = models.ManyToManyField( to='Hashtag', through='TweetHashtag', through_fields=('tweet', 'hashtag'), ) ... class TweetHashtag(models.Model): comment = models.ForeignKey( to='Tweet', on_delete=models.CASCADE, ) hashtag = models.ForeignKey( to='Hashtag', on_delete=models.CASCADE, related_name="tweets" ) created = models.DateTimeField(auto_now_add=True) My problem is when I get a Tweet, I want to get hashtags order by created. tweet = Tweet.objects.get(id=1) hashtags = list(tweet.hashtags.all()) When I check hashtags, I see the hashtags are in incorrect ordering. I want to get tweet.hashtags order by created (created of TweetHashtag) Is there anyway? I have one idea but I don't know how to do that. The idea is to override relation manager of hashtags in Tweet model. Is there any way? -

Whitenoise Not Working when DEBUG = FALSE - Django - Hosting Static Files
I am running a Django website and it's about to go into production. I am now at the point where I need to set DEBUG = False in my settings.py file. I am getting the typical 500 errors because I have static files that are being hosted locally. I am working on getting Whitenoise to work to host my static files so I can move on with DEBUG = False. I have followed a lot of documentation and a lot of tutorials and think all of my configurations are all set but I am still getting the same error. When DEBUG = False I am still getting 500 errors on my production pages that have static files. Also when I inspect any static files on the page when DEBUG = True the URL has not changed at all. I am posting all of my configuration below in hopes that there is a simple mistake I made that I have been continuously skipped over but Whitenoise doesn't seem to be working and there seems to be no different from the way it was before now as Whitenoise is "implemented". I have run python manage.py collect static I have run pip install … -

Checking message value in Django template
I am working with a Google ReCaptcha on a Django site and would like to check the value of the error messages. If the value is 'Invalid reCAPTCHA. Please try again.' then I would like to show an error message under the ReCaptcha. However, the way that I have this set up is not currently working. <div id="g-recaptcha-error"> {% if messages %} {% for message in messages %} {% if message is 'Invalid reCAPTCHA. Please try again.' %} <span style="color:red;">{{ message }}</span> {% endif %} {% endfor %} {% endif %} </div> How do I check the actual value of the recaptcha message? There could possibly be additional errors so I don't want this to show up if the value is different. When I include this below it shows 'Invalid reCAPTCHA. Please try again. test' So I know the message is correct. {% for message in messages %} <p>{{ message }} test</p> {% endfor %} -
How do I connect django-tinymce with the javascript from TinyMCE?
I have successfully added TinyMCE to my site using the django-tinymce library in the fields in my admin. Looking through a lot of posts on here, there seems to be a utility in adding some javascript, too, but the installation guide does not mention javascript. I have attempted downloading TinyMCE js from the official site and added it in my static/js folder, and then added this to my settings.py: STATIC_URL = '/static/' TINYMCE_JS_URL = os.path.join(STATIC_URL, "js/tinymce/tinymce.min.js") But it did not change anything, so I suspect it does not work. After looking through tons of documentation, posts here and Youtube guides, I have not come to a conclusion. So I have two questions: What is the benefit of adding javascript from TinyMCE to my site - besides the django-tinymce plugin? How do I add it to my site given I already have the django-tinymce installed? EDIT: I actually already know one utility that I want from the js. That is, I want to be able to not include image dimensions in the HTML output of the TinyMCE forms of my admin. Apparently this is edited in the JS - unless the option can be edited elsewhere? -
Django Rest Framework modify field value depending on condition
as a Python, Django and DRF newbie I have a very basic question when building a Rest API for a test project. I am sure the experts here can assist me on this as it is really more than simple (but I run into the wrong direction): Below is the core extract of a very simple API endpoint. When the endpoint is called (GET) I want to return the "Description" value as it is stored in the database (this is clear of course). But if the field "ISO2CODE" has a value (for example "de") I want to change the "Description" value in the API to a different output (e.g. German). Means the API will not return the value in the database but a manipulated value. How should I do this. What is the common way to manage such a (simple) requirement (add a condition - how? in the model definition?). Thank you for any help on this. class Territory(models.Model): ISO2Code = models.CharField(max_length=2) Description = models.CharField(max_length=128) class Meta: ordering = ['pk'] class TerritorySerializer(serializers.ModelSerializer): class Meta: model = Territory fields = ['id', 'ISO2Code','Description'] class TerritoryViewSet(ModelViewSet): queryset = Territory.objects.all() serializer_class = TerritorySerializer def get_serializer_context(self): return {'request': self.request} -
How to handle conflicting basic auth from NGINX reverse proxy with JWT auth from Django?
we have a standard Django web app running behind a reverse proxy. I want to setup a two layer authentification : one from the nginx reverse proxy to shield the application (presently a HTTP Basic authentication -yes we plan to upgrade to something stronger like SSL client certificate or smartcards-), and one at the application level However we are currently running into a issue because the HTTP Basic Authorization header is conflicting with the Django Authorization header The problem arises because the JWT auth from Django requires us to fill the "Authorization" header with the token while NGINX uses another type of authentication. I'm looking for the best way to solve this problem and have the following questions : is it possible to require Django to use an alternative HTTP header to carry its authentication token (instead of "Authorization") or, conversely, is it possible to configure our nginx to use an alternative header for the HTTP Basic authentication (but it seems unlikely as it is done at the browser level) or to require the nginx to do the header translation : i.e. converting back and forth header before pushing them to the Django app. or, even better, can we configure … -
Django CORS Headers works when allowing all, but not for a specified origin
I have a React frontend (hosted at http://localhost:3000/) that is trying to send JWT refresh tokens via HttpOnly Cookies to a Django REST API (hosted at http://localhost:8000/, but tunnelled using ngrok to an https address). I am using django-cors-headers to deal with the cross-origin aspect of this. However, no matter what I do, I cannot seem to get this to work (despite days of research). Any help would be greatly appreciated :D I think I am addressing the endpoint correctly (i.e. https://ngrokapiurl/api/token/refresh/) and I have put 'corsheaders.middleware.CorsMiddleware', at the top of the middleware block. The CORS errors go away when I specify CORS_ORIGIN_ALLOW_ALL = True. However, not only do I understand that security-wise this is not ideal, but it also does not work when I set CORS_ALLOW_CREDENTIALS = True to allow the withCredentials: True part of my axios request to send over the HttpOnly cookie containing the refresh token. Therefore, I remove the CORS_ORIGIN_ALLOW_ALL = True and set CORS_ALLOWED_ORIGINS = [ "http://localhost:3000", ] to specify the allowed origin. However, it is at this point that nothing seems to work. Please help me fix this - I am very new to all of this! The error I get is: error In … -

Django Serializers - Datetime with multiple possible formats
I want my Django Serializer to validate the format of a date according to several possible formats. Essentially, these formats are: just the date (YYYY-MM-DD) date + hours (YYYY-MM-DD HH) date + hours + minutes (YYYY-MM-DD HH:MM) date + hours + minutes + seconds (YYYY-MM-DD HH:MM:SS) I know that the final two are possible together, using the DateTimeField with format= '%Y-%m-%d %H:%M:%S. I know the first one is possible by default using the DateField. I assume the second one is possible using the DateTimeField with format= '%Y-%m-%d %H', but I haven't tested. What I want to know is: is there a straightforward way to combine all these validators together, without having to use custom functions/validators? For example, my first instinct was to provide a list of possible formats to the format parameter on the Date/DateTime fields, but with no success. Is there something I'm missing? -
