Websocket close with 200 status
I have setup websocket using nginx and daphne. I am also using gunicorn for handling http request. I apply the same setting in previous server it works fine now in the new server with the same setting the websocket is returning 200 satus and not connecting. Console log: WebSocket connection to 'wss://ubl.mn/ws/2/' failed: Error during WebSocket handshake: Unexpectedresponse code: 200 Daphne log: 127.0.0.1:25894 - - [22/Nov/2020:18:35:51] "GET /ws/2/" 200 3146 127.0.0.1:25900 - - [22/Nov/2020:18:36:02] "GET /ws/2/" 200 3146 The log of where the websocket is working is: 127.0.0.1:9596 - - [22/Nov/2020:18:49:09] "WSCONNECT /ws/6512/" - - 127.0.0.1:9596 - - [22/Nov/2020:18:49:54] "WSDISCONNECT /ws/6512/" - - So it seems the difference between working and not working server is in daphne log one has GET and another request has WSCONNECT like that. I don't want to post all code here at first, can someone please point to me where I may have made the mistake I can provide further info about it. -
How could I save multiple users by using a checkbox with a ManyToMany relationship?
I already did create 4 objects in Role table which refers to the role of users in website. the Role was a list but I created it in User model as a checkbox input to allow the user to choose what he wants among roles but I can't save my data that comes through cleaned_data which refers to roles data, I get the following error: 'RegisterForm' object has no attribute 'roles' in forms.py file what I miss here? here is my code: forms.py from django import forms from django.contrib.auth.forms import UserCreationForm from .models import User, Profile, Role class RegisterForm(UserCreationForm): password1 = forms.CharField(min_length=4, widget=forms.PasswordInput(attrs={ 'placeholder': 'Password' }), label='password') password2 = forms.CharField(min_length=4, widget=forms.PasswordInput(attrs={ 'placeholder': 'Confirm Password' }), label='Confirm Password') class Meta: model = User fields = ['email', 'first_name', 'last_name', 'roles', 'password1'] widgets = { 'roles': forms.CheckboxSelectMultiple() } def clean_password2(self): password = self.cleaned_data['password1'] password2 = self.cleaned_data['password2'] if password and password2 and password != password2: raise forms.ValidationError("password and confirm password is not same") if len(password) < 4: raise forms.ValidationError('Password is very weak please enter 4 words at least') return password def save(self, commit=True): user = super().save(commit=False) if commit: user.staff = True user.set_password(self.cleaned_data['password1']) self.roles.add(self.cleaned_data['roles']) user.save() return user models.py from django.db import models from django.contrib.auth.models import … -
getting unexpected/unwanted url path when clicking on an href link in django
so, here are all the urls i defined: path("", views.index, name="index"), path("login", views.login_view, name="login"), path("logout", views.logout_view, name="logout"), path("register", views.register, name="register"), path("new", views.new.as_view(), name="new"), path("<int:user>/watchlist", views.watchlist, name="watchlist"), path("<int:user>/<str:name>", views.name, name="name"), path("<str:user>/<str:name>/watchlist/remove", views.remove, name="remove-from-watchlist"), path("<int:user>/<str:name>/watchlist/add", views.add, name="add-to-watchlist"), path("<str:user>/<str:name>/bid", views.bid, name="bid"), path("<str:user>/<str:name>/close", views.close, name="close-bid"), path("<str:user>/<str:name>/comment", views.comment, name="comment"), path("add-category", views.addC, name="add-Category"), path("categories", views.categories, name="categories"), path("<str:cat>/category", views.cat, name="category-page") From experience, the problem is with all the 'watchlist' related URLs. For example, when i am on index view, the path to path("<int:user>/watchlist", views.watchlist, name="watchlist"), is <a class="nav-link" href="{{ user.id }}/watchlist">Watchlist</a> and the url path shows the same - http://127.0.0.1:8000/2/watchlist where 2 is the user id. Then when i go to a url <a class="nav-link" href="categories">Categories</a> the url path followed is http://127.0.0.1:8000/2/categories the '2' should not be there! I specifically hard coded the path in the anchor tag I am facing another problem: when i am at the index view and i click on the anchor tag containing <a href=/{{ user.id }}/{{ item.Title }} where item.Title is say "Magic Broom", the url path i am getting is http://127.0.0.1:8000/2/Magic while it should have been http://127.0.0.1:8000/2/Magic Broom Can someone please explain what's going on here... -

Save data to database from Django Channels consumer
I'm having an hard time editing a database entry from a Django channels consumer, here is the piece of code involved: class TestConsumer(AsyncJsonWebsocketConsumer): async def websocket_connect(self, event): ... key_query.active_connections = 2 key_query.save() ... Since i'm using an asynchronous consumer, this will give me the following error: You cannot call this from an async context - use a thread or sync_to_async.

How to refresh the form fields and view after a different app update's the database? Django, Python

After upgrading to PostgreSQL default value for ImageField does not work (Django)
Since shifting to PostgreSQL (from SQLite) the default value for ImageField does not work. If I select and upload the image manually everything is fine.

Django: Show downloadable custom log file
I have a small Django Project, where the user can uplaod a csv file which is parsed to the Database. If there are some formating issues detected during the processing I write them into a pd.DataFrame and want to show them to the user afterwards, so they know which lines of the csv could not be processed correctly. I thought about a few ways to do this. I could create a custom model only for the log, but I want the user to be able to download the log, which is why I would prefer to save the Log to a csv and show a download Link as well as the content of the Log, but I don't know how to do it or if there is a better way? My Code looks something like this: class ListVerifyView(ListView): def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) ... return context def post(self, request, *args, **kwargs): for k, v in request.POST.items(): try: col_dict[v] = int(k) except ValueError: pass ... error_log = pd.DataFrame(columns=['Chemical', 'Error']) ... if not error_log.empty: messages.add_message(self.request, messages.WARNING, 'Some ERRORS occurred during import!') return HttpResponseRedirect(reverse_lazy('show_error')) return HttpResponseRedirect(reverse_lazy('home')) I thought about saving the Log as a models.FileField and pass the pk to reverse_lazy('show_error') but … -
Render include tag with conditional variable
I have a sub-template that renders a typical table, based on a variable transaction_items, as following: <table id="order-list" class="order-list order-list-hoverable"> <thead> <tr class="w3-light-grey"> <th>Item</th> <th>Qty</th> <th>Total</th> </tr> </thead> <tbody> {% for transaction_item in transaction_items %} <tr id="order{{forloop.counter}}{{transaction_item.name}}" data-order_modal="{{transaction_item.name}}order{{forloop.counter}}"> <td>{{transaction_item.name}}</td> <td>{{transaction_item.quantity}}</td> <td>{{transaction_item.get_total_cost}}</td> </tr> {% endfor %} </tbody> </table> In a parent template, I would like to use include tag to call this template as following: {% include "order_summary.html" with transaction_items=transaction_items_N %} Suppose I have N buttons that, when clicked, return a variable transaction_items_N. I would like to immediately re-render the above table with the new transaction_items_N. How do I make the include tag accept this kind of dynamic variable-parsing in the template? Or mus this be done with JavaScript? Thanks. -

How to display just the tags in form instead of all the list elements in Django?
I have a form used to create and edit an object on Django, and I'm trying to implement tags with django-taggit and Crispy Forms. Currently it's working great to create the tags, and it creates a list of tags for the field. When I want to edit the object I get the field pre-populated with those tags, but they are not 'flattened', so the tags show as: [<Tag:Tag1> <Tag:Tag2> <Tag:Tag3>] rather than just Tag1 Tag2 Tag3 And if the object contains no tags there is [] in the form field. My view to edit the objects is: def edit_recipe(request, recipe_id): """Edit an existing recipe""" recipe = get_object_or_404(Recipe, pk=recipe_id) if request.method == "POST": form = RecipeForm(request.POST, request.FILES, instance=recipe) if form.is_valid(): form.save() messages.success(request, "Successfully updated recipe.") return redirect(reverse("recipes")) else: messages.error(request, "Failed to update. Please check the form.") else: form = RecipeForm(instance=recipe) template = "recipes/edit_recipe.html" context = {"form": form, "recipe": recipe} return render(request, template, context) My model includes the field tags as so: tags = TaggableManager(blank=True) And my form is: class RecipeForm(forms.ModelForm): class Meta: model = Recipe fields = ( ...

Add CSS to form field in django template
I want to use bootstrap on django form. To do so I need to add .form-control class to each field.

How can I move the class to template? I would not like to use crispy not to be bound to bootstrap. -
TinyMCE with DigitalOcean Space in Django
I am currently working on building blog site using django and DigitalOcean Space. I've connected everything so static and media files automatically get saved to DigitalOcean space. However, I've been trying to get images in content (TinyMCE HTMLField()) get saved to DigitalOcean Space but seems to be not working.
