Django Use a String as ForeignKey
I have a quick conceptual question that I would like to solve. I have a model that upon saving an instance of that model, saves the id as an md5 hash (ex. '11db608cba69c0a09b4d5abde2553b56'). Saving this model works fine, but now I am trying to save additional information by creating a new model that references this model as a foreign key. Upon saving that additional model I get the following error: invalid literal for int() with base 10: '11db608cba69c0a09b4d5abde2553b56'. Doing some searching I found a nice stack post that answers what I believe to be happening. It said that by default, a ForeignKey field is of type integer. Therefore whatever value is referenced by it must be an integer. I would like to be able to define a model that uses a str-based foreign key (or anything that will allow it to except the md5 hash). Is that solution possible? The only other thing I could think of doing is generating an integer based on the md5 and using that as a reference, but it seems like an unnecessary step. I also found some other posts that referenced GenericForeignKey. I'm having a bit of trouble wrapping my head around it, but … -
How to implement Giphy into blog post comments in Django?
I would like to offer the option to insert Gifs via the Giphy API into blog post comments for my readers. I have a plain vanilla comment form + model like so: forms.py # Blog Post Comment Form class CommentForm(forms.ModelForm): class Meta: model = Comment fields = ('name', 'text',) models.py # Comment Model class Comment(models.Model): post = models.ForeignKey('blog.Post', on_delete=models.CASCADE, related_name='comments') name = models.CharField(max_length=200) text = models.TextField() created_date = models.DateTimeField(default=timezone.now) approved_comment = models.BooleanField(default=True) def approve(self): self.approved_comment = True self.save() def __str__(self): return self.text Now I am stuck when it comes to the basic concept of how I could implement the Giphy API into the form/model instances. My idea is to make an async Ajax call to the Giphy API endpoint once the user entered a search term. Then the API would return a bunch of gifs and the user selects one. I guess that the Django Textfield isn't capable for this purpose. Now how to insert the selected gif into the comment and save it to the database? -

AWS Elastic Beanstalk failed to install Python package using requirements.txt - Firebase-Admin
I have searched similar questions, but no answers solve my problem. I am trying to install firebase-admin using pip. Everything works well locally, but when I push to aws elastic beanstalk it gives me the error below When I remove firebase-admin and its dependencies everything works fine. I think it may specifically have an error with grpcio being installed but not completely sure, and firebase needs it installed to work. Some answers say that firebase-admin is dynamic and aws else does not support that. I am wondering if there is a solution to this problem so I can install firebase.

django ckeditor set with different s3 bucket
I'm implementing ckeditor with my django app, the problem I have is: Django-ckeditor doesn't work with s3 buckets that are not public. I need the s3 bucket to be private to prevent abuse. My thoughts are setting the django-ckeditor upload to a different s3 bucket and setting it as public. I want to know if that is possible as that isn't documented by django-ckeditor. If I set the s3 bucket to be public, will people be able to upload files outside my sites (does setting it public ignores CORS settings)? If the above thought is incorrect, is there an alternative way of doing it without affecting my main media storage?, or an alternative package for rich text editor. Thanks in advance. -
Use entire set of views in two different URL confs in Django
I'm building a web app that displays TV Shows and Episodes. All my urls are geared towards TV Shows being the top level concept: mysite.com/tv-show-name/episode-name mysite.com/tv-show-name/episode-name/cast mysite.com/tv-show-name/episode-name/reviews I've gotten interest from Networks for consolidated pages with their shows as subdirectories mysite.com/network-name/tv-show-name/episode-name mysite.com/network-name/tv-show-name/episode-name/cast mysite.com/network-name/tv-show-name/episode-name/reviews I'll need to support both, and obviously I dont want to repeat all my non-network URL confs. Is there a simple way to do this? -

Django model attribute and database field with different name in model

Controlling duplicate entries with Django
Django offers the possibility to use the * exists * function which returns a boolean a = Predicates.objects.filter(predicate = predicate).exists() print (a) True I need to occupy the ID (PK) of that record if it exists so I use get try: return Predicates.objects.get(predicate = predicate) except Predicates.DoesNotExist as errorNoExiste: return None That code in a function exists = self.search_predicate (predicate) now on reaching the conditional if exists is None: if or if you enter and proceed to save, which produces a Duplicate Entry in the model the attribute is obviously unique. Any ideas as I said I need the ID of the record if there is to make another record and why this ID is your FK (instance). -
Django Rest Framework : get_queryset returns 'detail': 'Not found'

Django channels zero downtime code update?
I have a django channels based app in production environment. I am using supervisord to manage processes. Also I am using uvicorn via gunicorn to handle asgi requests as mentioned here. Whenever I have something new to deploy, I have to restart gunicorn process and it will destroy all old websocket connections and connect them again. Is there a way to persist those websocket connections. Basically, it puts a sudden load on server as every device tries to reconnect after few seconds of disconnection. There is concept of sending HUP signal Link to gunicorn so that only workers processes restart, but even restarting worker processes disconnects websocket connection. Is there a way to do it without losing old websocket connections? Or if not is there a way to avoid sudden load on server on server restart? Can I do it using some proxy server? -
Nginx will not serve django media files, but will serve static files
I am hosting a django docker container on digital ocean. The container uses nginx to handle django static and media files. I am able to serve static files, but not media files.

Is my forms.py correct? class CustomUserCreationForm(UserCreationForm): first_name = forms.CharField(max_length=30, label='First Name') last_name = forms.CharField(max_length=30, label='Last Name') class Meta: model = CustomUser fields = ('email', 'first_name', 'last_name') def save(self, request): user = CustomUserCreationForm(request.POST) user.first_name = self.cleaned_data['first_name'] user.last_name = self.cleaned_data['last_name'] user.save() My All Auth Settings ACCOUNT_EMAIL_REQUIRED = True ACCOUNT_EMAIL_VERIFICATION = 'mandatory' ACCOUNT_EMAIL_CONFIRMATION_EXPIRE_DAYS = 7 ACCOUNT_USERNAME_REQUIRED = False ACCOUNT_SIGNUP_PASSWORD_ENTER_TWICE = False ACCOUNT_SESSION_REMEMBER = True ACCOUNT_AUTHENTICATION_METHOD = 'email' ACCOUNT_UNIQUE_EMAIL = True ACCOUNT_EMAIL_CONFIRMATION_ANONYMOUS_REDIRECT_URL = LOGOUT_REDIRECT_URL ACCOUNT_EMAIL_CONFIRMATION_AUTHENTICATED_REDIRECT_URL = None ACCOUNT_LOGIN_ATTEMPTS_LIMIT = 5 ACCOUNT_LOGIN_ATTEMPTS_TIMEOUT = 300 ACCOUNT_USERNAME_BLACKLIST = ['admin', 'superuser', 'user'] I didn't change anything in the ACCOUNT_FORMS dictionary. Its the default. Thank you very much. -

TypeError: Object of type Reporter is not JSON serializable
I am trying to add the reporter with ajax but it is not working properly. When I send json data with {'reporter':reporter.name} then it creates the obj in the database successfully but I am not being able to display this newly created obj in the select option. I have to refresh to see this object in the select option. Then I tried sending the object instance as a JsonResponse by dumping with json.dumps(obj) but I am getting this error serializable error. I have to create the reporter object and display in the select option without page refresh. How can I do it ? What's wrong here in my approach ? view class AddReporterView(View): def post(self, request): name = request.POST.get('name') reporter = Reporter.objects.create(name=name) data = { 'reporter': json.dumps(reporter) } return JsonResponse(data) Scripts $(document).on('submit','#target-category-form',function(e) { e.preventDefault(); var form = $(this); $.ajax({ url: form.attr("action"), data: { name:$('#name').val(), csrfmiddlewaretoken:$('input[name=csrfmiddlewaretoken]').val(), }, type: 'POST', dataType:'json', success: handleFormSuccess, }); }); function handleFormSuccess(data){ $("#id-categories").html(data); $('#modalOpen').modal('toggle'); console.log(data); } I want to display the created data here in this html select element <select class="form-control" name="reporter" multiple="multiple" id="id-categories"> {% for reporter in reporters %} <option value="{{reporter.pk}}">{{reporter.name}}</option> {% endfor %} </select>
