Accessing Django View data fro JavaScript using Fetch Api
I'm trying to get data from Django view using fetch API but the fetch API isn't reaching the Django view. function connect(username) { alert('connect'); let promise = new Promise((resolve, reject) => { // get a token from the back end let data; alert("before append") // data.append('csrfmiddlewaretoken', $('#csrf- helperinput[name="csrfmiddlewaretoken"]').attr('value')); alert("vc") fetch("/videocall/", { method: 'POST', // headers: { // "X-CSRFToken": getCookie("csrftoken"), // "Accept": "application/json", // "Content-Type": "application/json" // }, headers:{ 'Accept': 'application/json', 'X-Requested-With': 'XMLHttpRequest', //Necessary to work with request.is_ajax() 'X-CSRFToken': csrftoken, }, //credentials: "same-origin", body: JSON.stringify({'username': username}) }).then(res => res.json()).then(_data => { // join video call alert("Joint") data = _data; return Twilio.Video.connect(data.token); }).then(_room => { alert("room") room = _room; room.participants.forEach(participantConnected); room.on('participantConnected', participantConnected); room.on('participantDisconnected', participantDisconnected); connected = true; updateParticipantCount(); connectChat(data.token, data.conversation_sid); resolve(); }).catch(e => { alert("catch") console.log(e); reject(); }); alert(promise) }); return promise; }; Here's my django view def videocall(request): print("Trying to login") if request.method == "POST": print("Trying to login") It's not even printing trying to login which i printed in django view. I think there's some problem in URL in fetch. I'm new to Django please help me in this regard -
Multiple classes with the same name firing on a single class click
I have the script below to like or unlike a particular post, but the posts are displayed using a for loop in Django so they all have the same class. When an upper like button is clicked, all of the remaining buttons are also clicked which I suspect is due to the jquery. I tried the solution in this thread to add StopPropagation and ImmediatePropagation but it's not working jQuery $(".class").click(); - multiple elements, click event once The Jquery code $('a.like').on('click', function(event){ event.preventDefault(); event.stopPropagation(); event.stopImmediatePropagation(); $.post('{% url "posts:post_like" %}', { id: $(this).data('id'), action: $(this).data('action') }, function(data){ if (data['status'] == 'ok') { var previous_action = $('a.like').data('action'); // toggle data-action $('a.like').data('action', previous_action == 'like' ? 'unlike' : 'like'); // toggle link text $('a.like').text(previous_action == 'like' ? 'Unlike' : 'Like'); // update total likes var previous_likes = parseInt($('span.count .total').text()); $('span.count .total').text(previous_action == 'like' ? previous_likes + 1 : previous_likes - 1); } } ); }); In the image, all three of the 'like' links would change to unlike when a single one is clicked [![Image of the output][1]][1] [1]: https://i.stack.imgur.com/qXuwz.png -

How to serialize some nested relational models in django using rest?
I have some django models with different relations to each other (i.e. Many-to-many, Foreinkey). Now, I want to serialize them using djnago-rest. Here's an example of my models and their relations: class CommonFieldsAbstarct(models.Model): name = models.CharField(max_length=30, unique=True) class ServerModel(CommonFieldsAbstarct): server_ip = models.GenericIPAddressField(default='172.17.0.1') server_port = models.IntegerField(default='9001') class SNMPLineModel(CommonFieldsAbstarct): ip_address = models.GenericIPAddressField() port = models.IntegerField(default=161) class SNMPModel(CommonFieldsAbstarct): # target line = models.ForeignKey(SNMPLineModel, on_delete=CASCADE) servers = models.ManyToManyField(ServerModel) class MetaDataModel(models.Model): key = models.CharField(max_length=20) value = models.CharField(max_length=20) snmp_device = models.ForeignKey(SNMPModel, on_delete=CASCADE) Before, I used to use this way to create json manually: def meta_data_json(meta_data): meta_data_list = [] for meta in meta_data: meta_data_list.append({ meta.key: meta.value }) return meta_data_list def server_json(servers): return [{'ip': server.server_ip, 'port': server.server_port} for server in servers] def create_json(): snmp = SNMPModel.objects.filter(name__contains='a-name') return { 'name': snmp.name, 'address': snmp.line.ip_address, 'port': snmp.line.port, 'servers': server_json(snmp.servers.all()), 'meta_data': meta_data_json(MetaDataModel.objects.filter( snmp_device=snmp.pk ) ), 'device_pk': snmp.pk } My Question: Now, how can I create such an above json through django-rest-framework instead? I don't have any problem with many-to-many. In fact, my problem is with their foreignkey(s). And here is what I've done so far: serializers.py from rest_framework import serializers class MetaDataSerializer(serializers.ModelSerializer): class Meta: fields = [ 'id', 'key', 'value', ] model = MetaDataModel class ServerSerializer(serializers.ModelSerializer): class Meta: fields = [ 'id', … -
AttributeError: 'str' object has no attribute 'as_widget'
I am trying to have more control of my Django forms by adding a custom filter from django import template register = template.Library() @register.filter(name='addclass') def addclass(value, arg): return value.as_widget(attrs={'class': arg}) but getting the AttributeError: 'str' object has no attribute 'as_widget' error here is my view def index(request): notes = Note.objects.all() form = NoteForm() if request.method == 'POST': form = NoteForm(request.POST) if form.is_valid(): form.save() return redirect('keep:index') context = {'notes':notes, 'form':form} return render(request,'Keep/note_form.html',context) def update(request,id): notes = Note.objects.get(id=id) form = NoteForm(instance=notes) if request.method == 'POST': form = NoteForm(request.POST, instance=notes) if form.is_valid(): form.save() return redirect('keep:index') context = {'notes': notes, 'form': form} return render(request,"Keep/update.html",context) def delete(request,id): obj = get_object_or_404(Note,id=id) if request.method == "POST": obj.delete() return redirect('keep:index') return render(request,"Keep/delete.html") PS. Before you throw me links to other similar questions, i want you to know i checked pretty much all the links and none of the solutions worked for me. Most common is this: else: form = UserForm() return render(request, 'register_user.html', {'form': form}) but as you can see, i did exact same thing but that doesn't work -

Twitter OAuth page asks user to re-authorize app, even though they've done it before
Say a user logged into Twitter comes to my site. Assume they have authorized my app. If I send that user to the OAuth authorization page, it keeps asking the user to (re-)authorize my app, even though they've done it a million times. Is there a way to skip the authorization process if they've already done it? Here's my code: #views.py def oauth(request): auth = tweepy.OAuthHandler(CONSUMER_KEY, CONSUMER_SECRET) auth_url = auth.get_authorization_url() request.session['request_token'] = auth.request_token return redirect(auth_url) get_authorization_url() seems to send my user to a re-authorization page no matter how many times they've authorized my app. I need it to skip this and redirect to my callback URL if they've already granted permissions. Anyone has any tips? -

Django jinja values not passed in correctly to iframe url (open streetmap)
I have tried several ways to incorporate an openstreetmap via iframe into my django app. I can see the map fine and can zoom in or out, but it is always a map of Antigua. I want to embed a small map in my django template and pass in latitude and longitude from jinja. It makes no difference whether I pass in hard coded lon and lat or jinja, I still get the same map in openstreetmaps. I started with this template from the openstreetmaps wiki https://wiki.openstreetmap.org/wiki/OpenLinkMap : <iframe width="420" height="350" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="http://www.openlinkmap.org/small.php?lat=<LAT>&lon=<LON>&zoom=<ZOOM>" style="border: 1px solid black"></iframe> No matter whether I hard code or put dynamic values, I see a map of Antigua.

downloading files from firebase storage, python
I'm trying to download files from my firebase storage with python, and I can't seem to figure out how. I've tried a bunch of different tutorials. So I have the credentials set up as an enviromental path: os.environ["GOOGLE_APPLICATION_CREDENTIALS"] = credentials.json' and then based off what I've seen online, I tried this to donwnload the file from storage. In firebase storage it's just located in the base directory, so I did: storer = storage.child("project_name.appspot.com").download("path_to_file_in_storage") I already have initialized firebase using this: cred = credentials.Certificate('credentials.json') firebase_admin.initialize_app(cred) This clearly is incorrect, so how would I go about doing this? -

The dictionary ("sum_by_date") is of working hours per date e.g. {'2020-10-09':1.5,'2020-10-10':2}. I want a graph with bars, the dates on x - axis and the hours on y-axis and a line between the dots. What is the simplest way to do so? I want something equivalent to : pyplot.bar(*zip(*sum_by_date.items())) of matplotlib.pyplot. Thank you
