Images are not showing in a Django web app deployed on Heroku
I have a Django app deployed on Heroku the problem is that when I upload an image to the app, it's uploaded fine and it keeps being shown for sometime, when I close the app for a long time and come back the images become corrupted and not shown.

Getting objects before validating data Django REST
I have to create a new Chat object using this view: class ChatListCreateView(ListCreateAPIView): permission_classes = [IsAuthenticated] serializer_class = ChatSerializer def get_queryset(self): data = Chat.objects.filter( Q(employees=self.request.user) | Q(created_by=self.request.user)).distinct() return data The serializer it uses is: class ChatSerializer(serializers.ModelSerializer): created_by = SimpleEmployeeSerializer(read_only=True) employees = SimpleEmployeeSerializer(many=True, read_only=True) title = serializers.CharField(max_length=255) def create(self, validated_data): """ Creates a new Chat and adds the m2m employees to it """ # Create and save the chat chat = Chat.objects.create( created_by=self.context['request'].user, title=validated_data['title'], ) # Add the employees to the chat validated_employees = validated_data.pop('employees') for user_id in validated_employees: employee = Employee.objects.get(id=user_id) chat.employees.add(employee) return chat My issue is that the SimpleEmployeeSerializer expects a user object but I am submitting an array of employees as such: { "title": "fwef", "employees": [ { "id": "8" }, { "id": "30" } ] } What method can I implement to get the objects from these IDs before validation? -

How to do two separate Stripe payments with one click
I'm looking for a way to split a Stripe payment into two with one click, but one of the installments should be automatic while the other is based on a condition. I'm new to the Stripe API and relatively new to Django as well. It looks like Stripe Connect would solve the issue of splitting the payment in two, but both installments would be triggered at the same time which I'm trying to avoid. I know this is a pretty vague question so I apologize in advance. But if anyone has an idea how I could implement this please let me know! Thanks -

Adding markdown highlighted fenced block to django app with markdonx
I have been looking through the documentation but I can’t seem to get this to work. I wish to publish posts from a “creation page”. I want to use the editor markdownx. I got it to work, however there is no “fenced code support”. I tried to add the following line of code to my settings.py MARKDOWNX_MARKDOWN_EXTENSIONS = ['fenced_code'] but it breaks the code, in fact I get the following error (when I try to create a post): SyntaxError at /markdownx/markdownify/ if I erase the extensions list, it works fine. I would like also to use the codehilite extension by adding it to the list like this MARKDOWNX_MARKDOWN_EXTENSIONS = ['fenced_code' ,'codehilite'] but it does not work. I have installed pigments but the documentation does not seem to help. Could someone help me add this extensions correctly, getting highlighted code blocks to work. Thank you very much. -
Django Rest-Framework search-fields wont work inside @action
I'm trying to use the search field offered by DRF inside of an action, but it seems to not work. I had a similar problem paginating inside of the action but found a solution. My guess is that it's overriding the ModelViewSet so I have to manually add the filtering, but is there a way to use the same search_fields offered by DRF. Here's my code: class XViewSet(ModelViewSet): queryset = X.objects.all() serializer_class = XSerializer permission_classes = [IsAdminUser] filter_backends = (SearchFilter,OrderingFilter) search_fields = ['a','b','c','d'] @action(detail=False, methods=['GET'], permission_classes=[IsAuthenticated]) def me(self, request): query = X.objects.filter(ex_id=request.user.id) if request.method == 'GET': serializer = XSerializer(query, many=True) return Response(serializer.data) Any help is appreciated, Thank you :) -

error in migration with legacy database in Django
I'm working on creating a filter in django where the options displayed are coming from a new column in the database. It turns out that this column was created directly in the database and so that it could be displayed in my template, I need to capture this field in the models. After some research, I found in django's own documentation a function called "inspectdb" that is called by manage.py. So far so good, after executing the function, the database fields are added to my project so that they can be directed to their corresponding app.models. The documentation indicates that I must perform a python manage.py migrate for the sync to complete, this snippet of code is where the problem happens. When performing the migrate, I get the following error: "django.db.utils.ProgrammingError: relation "crontabmanager" already exists" The "crontabmanager" table actually exists in my database, but it is not changing at this time. Some actions were taken to try to get around this problem, for example: I tried to ignore the migration and use the new field directly in the system, but it returns stating that the new column does not exist Delete the migration file and create a new "makemigration" Delete … -
Use Facebook and Google social login urls only in django all auth
For normal signin/signup i'm using django's default singin/signup, but in facebook and google login i'm using django allauth, and to implement django allauth i have to add all its urls by adding: path('accounts/', include('allauth.urls')), But i don't need all the allauth urls, i only need the ones that are related to facebook and google social login. So how do i add only the ones that are needed for facebook and google login to run i tried this: path("accounts/", include("allauth.socialaccount.providers.google.urls")), path("accounts/", include("allauth.socialaccount.providers.facebook.urls")), With these two lines Google login worked normally but facebook login worked at first steps but the last step where i'm redirected to /accounts/facebook/login/callback/?code=xxxxx... it returns error 500 I'm pretty sure the login was implemented correctly and the problem is in adding the needed urls because everything works normally when using include('allauth.urls') -
How to separate tables based on the model using FSM and FSM-Log?
I'm currently logging status changes to several models in my Django REST API using the django-fsm and django-fsm-log packages. However, all of the logs are stored in a single table. This is gonna end up being a massive table that will take time to run through to do analysis and reporting. To make it easier I'd like to either break out the logging table by each individual model or sort them by the highest level model that's associated. I'll explain what I mean. I have 3 models: class Status: CREATED = 'created' ACTIVE = 'active' CANCELLED = 'cancelled' COMPLETED = 'completed' STATUS_CHOICES = ( (Status.CREATED, 'Created'), (Status.ACTIVE, 'Active'), (Status.CANCELLED, 'Cancelled'), (Status.COMPLETED, 'Completed'), ) # model 1 #========= class Company(models.Model): name = models.CharField(max_length=255) # model 2 #========= class Order(models.Model): name = models.CharField(max_length=255) company = models.ForeignKey(Company, related_name='company_order', on_delete=models.CASCADE) current_status = FSMField(choices=STATUS_CHOICES, default=Status.CREATED) @fsm_log_by @fsm_log_description @transition(field=current_status, source=Status.CREATED, target=Status.ACTIVE) def order_created_to_active(self, by=None, description=None): return "order is now active" @fsm_log_by @fsm_log_description @transition(field=current_status, source=Status.ACTIVE, target=Status.COMPLETED) def order_active_to_completed(self, by=None, description=None): return "order has been completed" @fsm_log_by @fsm_log_description @transition(field=current_status, source=Status.ACTIVE, target=Status.CANCELLED) def order_active_to_cancelled(self, by=None, description=None): return "order has been cancelled" # model 3 #========= class Sale(models.Model): sale_amount = models.DecimalField(max_digits=19, decimal_places=4) description = models.CharField(max_length=1000) company = models.ForeignKey(Company, related_name='company_sale', on_delete=models.CASCADE) … -

How to get VScode Integrated Terminal Virtual Environment working?
I have completed a few courses online in Python and recently started a new course in Django. Previously I always used a virtual environment but would activate the environment myself, but in the course I am working through via Code with Mosh he shows a way to have VSCode activate the environment automatically in the terminal. I tried to follow along but am having a hard time getting this to work. First I tried following Mosh’s steps by locating the virtual environment location in terminal on the Mac using: pipenv --venv and this returned the location as /Users/lewpiper/.local/share/virtualenvs/storefront-7UYLLetM on my Mac. I then tried to to use this in the command palette with bin/python on the end of the path in VSCode to select the python interpreter and it didn’t seem to work. It seems like it didn't create the VSCode folder or JSON file that I saw in the lessons I was watching. Then I tried to edit the workspace settings in VSCode and add the following "python.pythonPath": "/Users/lewpiper/.local/share/virtualenvs/storefront-7UYLLetM"to match the VSCode file structure and again I am running into it not launching the terminal window with the virtual environment activated. Now when I click play in VSCode I … -
Button to hide contents of divs does not work in Django project
I have a javascript file with the following function: function sw(cl, v) { var a = document.getElementsByClassName(cl); for (var i=0; i<a.length; i++) a[i].style.display = v; } In my html file there is the following code: <script src="sw.js"> </script> <button onclick="sw('c1', ''); sw('c2', 'None'); sw('c3', 'None');">show c1</button> <button onclick="sw('c1', 'None'); sw('c2', ''); sw('c3', 'None');">show c2</button> <button onclick="sw('c1', 'None'); sw('c2', 'None'); sw('c3', '');">show c3</button> <div class="c1"> <!-- content --> </div> <div class="c2"> <!-- content --> </div> <div class="c3"> <!-- content --> </div> I tried using the function in a separate html file and it works, so do the buttons. However, I tried using that in a Django project and the buttons do not work. The mouse cursor does not change when I hover over a button but the button's color changes. The divs contain Django commands such as {% include "file.html" %}. Why won't the code work properly in the project? For context, I am trying to write a User Interface selector. The buttons are supposed to change what style is displayed. -
Flask print dict in jinja template with multiple values
I have a python/dict/flask/jinja printout problem with a dict containing multiple values. Basically. specialDict = {} specialDict[key]= Value printing it with {% for key, Value in specialDict.items() %} <a href=story/{{Value}}> <p class="fs-6 1h-1"> {{ key }} </p> </a> </ul> {% endfor %} works fine. BUT newspecialDict = {} newspecialDict[key]= Value1,Value2,Value3 printing it with the same code {% for key, Value in newspecialDict.items() %} <a href=story/{{Value}}> <p class="fs-6 1h-1"> {{ key }} </p> </a> </ul> {% endfor %} fails with KeyError : "('value1'," which is close but not "value1" . I understand flask/jinja is trying to unroll something and fails. Since for some reason python accepts dicts with multiple values even if the internet says its always just pairs of key, value (just one) there must be a way to print all the values in the template as part of the loop. tried and failed with unexpected {%: ... {% for key, value in newspecialDict.items() %} {% for innervalue in value.items() %} ... -
The new url id is getting appended after the previous request's url
I'm making a get request in django using html form as: crud.html <form action="{% url 'crudId' id %}" method="get"> <div class="col"> <div class="form-group" style="width: 20%;margin-top: 5px"> <label for="name">Id</label> <input type="number" name="id" value="{% if data %}{{ id }}{% endif %}"> </div> <input type="submit" value="OK" style="width: 30%; margin-left: 40%"> ... my view for this: class CrudPageView(View): def get(self, request, id=1): # get the id from the page oid = id ... # some data and operation ... return render(request, 'crud.html', {'data': data, 'id': oid}) and in urls.py as : path('crud/', CrudPageView.as_view(), name='crud'), path('crud/id=<int:id>', CrudPageView.as_view(), name='crudId') ... so http://localhost:8000/crud/ does work as intended and shows the page with data of id = 1; when I input any id, it also works as intended and shows the data for that id, but the url is in the form http://localhost:8000/crud/id=1?id=5 and after another input it will be http://localhost:8000/crud/id=5?id=12 What am I doing wrong?
