django permissions not being added to groups
I have created a project with x apps. My aim is to create groups with permissions attached to them that populate auth tables - 'auth_groups' 'auth_permissions' and 'auth_group_permissions' on initial migration & migrate Installed apps is up to date, tried with app name,i.e "morgue' and "morgue.apps.MorgueConfig" - used terminal to check apps in apps class. database: tried in both mysql and sqlite3 Problem: I am just trying to attach the default django perms to groups. Problem is some of the groups & permissions combo works whilst others will not add permissions to group. I have 10 groups 6 will do as required four will not. ~ see my code below for how i have attempted todo this. my code: from django.contrib.auth.management import create_permissions from django.contrib.auth.models import Group, Permission from django.db import migrations class Populator(object): def populate_groups(apps, schema_editor): # Create user groups user_roles = [ "Admin only", "Morgue only", ] for name in user_roles: Group.objects.create(name=name) for app_config in apps.get_app_configs(): app_config.models_module = True create_permissions(app_config, verbosity=0) app_config.models_module = None all_perms = Permission.objects.all() - does return all permissions # morgue - 'i substituted for permission.content_type.app_label, does exist in database' morgue_perms = [i for i in all_perms if i.content_type.app_label == "morgue"] # group is created … -
Upload Image in Django with Ajax
This question is asked many times. And after long time trying I gave up. I try to upload an image to the server with an Ajax function. The Ajax function does submit quite a lot of data (I deleted the unnecessary part). The console.log gives me an empty array. What is wrong with my function? Here is the HTML: <form method="POST" id="form-create" enctype="multipart/form-data"> {% csrf_token %} <input type="file" id="myImg" name="myImg"> </form> This is the script $(document).on('submit', '#form-create', function (e) { e.preventDefault() var formData = new FormData(); formData.append('myIMG', $('#myIMG')[0]); console.log(formData) $.ajax({ type: 'POST', cache: false, url: "{% url 'creator:build' %}", data: { img:formData, csrfmiddlewaretoken: $('input[name=csrfmiddlewaretoken]').val(), }, success: function (data){ if (data.msg === "Success") { $('h4').html('It worked!'); } if (data.msg === 'Fail') { $('h6').html('Sorry! There was a problem...'); } }, }); }); -
React Django Stripe Button
I have a react frontend and a Django/DRF backend. I am trying to create a button on the frontend that allows users to purchase a product via stripe. The below react code works fine for purchasing item. However, it does not register the purchase under specific user, meaning that you can purchase an item, but it is not linked to any user because it does not have the token (identifying the user who is making the purchase). return ( <section> <div className='product'> <img src='https://i.imgur.com/EHyR2nP.png' alt='The cover of Stubborn Attachments' /> <div className='description'> <h3>Stubborn Attachments</h3> <h5>$20.00</h5> </div> </div> <form action={`${API_URL}/api/stripe/create-checkout-session`} method='POST' > <button className='button' type='submit'> Checkout </button> </form> </section> ); }; Here is what I tried: const Playsub = () => { const purchase_item = () => async dispatch => { if (localStorage.getItem('access')) { const config = { headers: { 'Content-Type': 'application/json', 'Authorization': `JWT ${localStorage.getItem('access')}`, 'Accept': 'application/json' } }; const body = JSON.stringify({ token: localStorage.getItem('access') }); const res = await axios.post(`${API_URL}/api/stripe/create-checkout-session`, body, config) .then((res) => { console.log(res.data) }) .catch(err => { console.log(err.response.data) }); }}}; return ( <section> <form> <button onClick={purchase_item} className='button' type='submit'> Checkout </button> </form> </section> ); }; export default Playsub; The above code when clicking on the button created gives … -
How to send a message by time in a datatimefield in DJANGO?
Hello everyone I am making a REST application based on Django Rest. I have a mailing model and fields with the start date and the end date of the mailing. I would like the newsletter to be sent by the value in the creation date field and completed in the end date field. I am a beginner, and I have no ideas about implementing such an idea. Could it be Celery? class MailingList(models.Model): start_dt = models.DateTimeField() text = models.TextField(max_length=500) operator_code = models.ForeignKey( OperatorCode, related_name='+', on_delete=models.CASCADE, ) tag = models.ForeignKey( Tag, related_name='+', on_delete=models.CASCADE, ) end_dt = models.DateTimeField() -
Adding custom table for model in django admin panel
I want to add custom table to my model. I explored this question and found out that I should change change_list_results.html like this: {% load render_table from django_tables2 %} {% render_table table %} But I got bare table without sidebhars and so on. What did I do wrong? -
With Django Websockets, how can I subscribe the current user to a new group from views.py
In Django, I have models.py with Collection and Members as a relationship to them: # models.py class Collection(models.Model): name = models.CharField(max_length=100, null=False, blank=False) class Member(models.Model): account = models.ForeignKey(User, related_name="account_set", on_delete=models.CASCADE) collection = models.ForeignKey(Collection, related_name='members', on_delete=models.CASCADE) And I have a websocket for notifying members whenever we have changes in a collection that the user is member of. For that, I have MainConsumer, shown below. # consumers.py class MainConsumer(WebsocketConsumer): def connect(self): user_id = self.scope['user_id'] collection_ids = Member.objects.filter(account_id=user_id).values_list("collection_id", flat=True) for collection_id in collection_ids: async_to_sync(self.channel_layer.group_add)(f'collection_ws_{collection_id}' , self.channel_name) self.accept() Works like a charm. I can comunicate perfectly. Question is the following: If I create a new collection, I need somehow to tell my MainConsumer that the requested user should now receive notifications from this new collection as well. # views.py class CollectionCreate(generics.CreateAPIView): permission_classes = [IsAuthenticated, ] def create(self, request, *args, **kwargs): collection = Collection.objects.create(name=request.data['name']) # Create a member as admin member = Member.objects.create( collection=collection, account=request.user, ) ** -- Here I want to 'subscribe' the current user to this new collection as well, but I cant figure out how... -- ** return JsonResponse({"payload": CollectionSerializer(collection, many=False).data }, status=200) Worth mentioning that I could "reload" my websocket in the frontend and it works, but it seems a bit … -
Connect react static files within django app dynamically to AWS S3 bucket
I have been running a django app for a long time and now I need to integrate a React app within this project. I set it up successfully, but I am struggling with correctly connecting the static files. The main problem is that when building the react project it creates a path to the CSS and the JS file which is absolute (<link href="/static/css/main.849502n.css" rel="stylesheet">). What I tried to change this path is to simply add the homepage option in the package.json file "homepage": "../../../myproject/static/reactapp". Then I copied the static files from the react app to my django-static folder by adding to the build command: react-scripts build && cp -R build/static/ ../../myapp/static/reactapp This works locally, since in development I am using the static files stored in my app. But in production I am saving my static assets in an AWS bucket. The configuration for my production looks like this: STATIC_URL = "https://%s/%s/" % (AWS_S3_CUSTOM_DOMAIN, AWS_LOCATION) STATICFILES_DIRS = [os.path.join(BASE_DIR, "myapp/static"), os.path.join(BASE_DIR, "frontend/reactapp/build/static")] STATICFILES_STORAGE = "storages.backends.s3boto3.S3Boto3Storage" COLLECTFAST_STRATEGY = "collectfast.strategies.boto3.Boto3Strategy" AWS_STATIC_LOCATION = "static" For development: STATIC_URL = "/static/" STATICFILES_DIRS = [os.path.join(BASE_DIR, "myapp/static"), os.path.join(BASE_DIR, "frontend/reactapp/build/static")] STATICFILES_FINDERS = ( "django.contrib.staticfiles.finders.FileSystemFinder", "django.contrib.staticfiles.finders.AppDirectoriesFinder", ) My project structure: - djangoapp - frontend - reactapp - djangoapp - static … -

Get foreign key related JSON objects in Django template
So I currently have an API response that encodes a many-to-one relationship both ways, where the one object (called Sagas) has a set of the many objects (called Arcs) relating to it: //1 Saga contains many arcs in this way: //GET Saga [ { "id": 1, "arc_set": [ 1, 2, 3, 4, 5, 6 ], "name": "East Blue", "description": "The East Blue Saga is the introductory saga of the series...", "startChapter": 1, "endChapter": 100 }, ] //GET Arc [ { "id": 2, "name": "Orange Town", "description": "Luffy and his first crew member Zoro arrive at Orange Town where....", "startChapter": 8, "endChapter": 21, "saga": 1 }, ] basically I want to be able to go through the arc_set in my django template and grab the related arcs with the matching ids. It seems simple I'm just not too familiar with the django template syntax needed Currently all I've been working on is code to loop through the arc_set array and get the id values but I can't even get that to work, never mind getting the related Arc object: {% for saga in sagas|dictsort:'id' %} {% for arc_key, arc_id in saga.arc_set.items|dictsort:'id' %} but I've been unable to iterate through the arc_set … -

Is it worth having social signup on my website?
I am creating a website and I've already implemented the "Sign up with Google" button and i've already added the normal user creation form. i'm considering adding the "Sign up with Facebook" button but I'm not sure if it's worth it. I couldn't find any reliable statistics online about social signup market share and I was wondering if anyone else knew. I am open to other ways of signing up as well. -

How to set CustomUser’s field value inside APIView?

Can somebody tell me about this slash in path?
Can somebody tell me the difference between two paths? This is my urls.py in django urlpatterns = [ path('update/<int:id>/', views.update), ] urlpatterns = [ path('update/<int:id>', views.update), ] <form action="/app/update/{id}/" method="POST"> Why I should add slash(/) in the end of path? If I add / in path in urlpatterns, when I submit , it works well. If I don't, it occurs an error. -
Django + JS-Framework vs Django + native Javascript
I'm currently developing a website with a friend (Django + Django Templates with Bootstrap). It started as a learning project so we altered a lot during the development process. The project has around 30K to 40K lines of code and we tried a rather component based approach by including often used code fragments from external files with the django template language. By now, even if it started out as a learning project, we want to take it online when it's finished so it's supposed to handle mid to high web traffic in production. The question we're asking ourselves now is if it's worth migrating to a JS-Framework like Svelte or React since we'd like the website to be as fast as possible and we'd like to migrate it into a SPA. Would there be a benefit in using a framework like Svelte for realizing such goals or would this approach also be a suitable option for us? -

However how can I use multiple proxy_pass.
