PUT request not working in Django Rest - VueJS app
I'm trying to make a blog useing VueJS and Django with the REST Api (Ajax via Axios). I can send a "PUT" request without errors in the console bur it is not effecting the database, is link the method is not called. I also have a problem with setting by default the already-uploaded image in the input type="file" field. The code: Vuejs <template> <h1>ARTICOLO</h1> <form @submit="onSubmit"> <input type="text" name="title" placeholder="Titolo" v-model="form.title"> <input type="text" name="desc" placeholder="Descrizione" v-model="form.desc"> <input type="text" name="category" v-model="form.category"> <input type="file" name="image" @change="EditImage"> <input type="text" name="author" v-model="form.author"> <input type="text" name="author" v-model="form.slug"> <textarea name="text" v-model="form.text"></textarea> <p>{{ form }}</p> <button type="submit" @click= "onSubmit">Edit</button> </form> </template> <script> import axios from 'axios'; import { getAPI } from '../api' export default { data () { return{ Postslug: this.$route.params.Postslug, form: { title:"", desc:"", text:"", category:"", date:"", author:"", image:"", slug:"", }, selectedFile: '' } }, methods: { EditImage(event){ this.selectedFile = event.target.files[0] console.log(event); }, // Form method onSubmit(event){ const fd = new FormData(); fd.append('image', this.EditImage, this.EditImage.name) event.preventDefault(); axios.put(`http://127.0.0.1:8000/blog/api/edit/${this.Postslug}`, this.form).then(response => { this.form.title = response.data.title this.form.desc = response.data.desc this.form.text = response.data.text this.form.image = this.fd this.form.category = response.data.category this.form.author = response.data.author this.form.slug = response.data.slug }) .catch(err => { console.log(err) }) }, }, created() { getAPI.get(`blog/api/edit/${this.Postslug}`) .then(response => { this.form.title … -
How to use a Formset with Django_Tables2
I love using django_tables2 but I've hit a bit of a snag. I have an edit page with a standard django form for updating a member's details. Within this form there is a table of addresses for the current member which I can render easily with django_tables2 using the following code. from tables.py class AddressTable(tables.Table): address1 = tables.Column(attrs={'th':{'class':'centered nodec'}, 'td':{'data-title':'Address 1'}}) address2 = tables.Column(attrs={'th':{'class':'centered nodec'}, 'td':{'data-title':'Address 2'}}) address3 = tables.Column(attrs={'th':{'class':'centered nodec'}, 'td':{'data-title':'Address 3'}}) address4 = tables.Column(attrs={'th':{'class':'centered nodec'}, 'td':{'data-title':'Address 4'}}) address5 = tables.Column(attrs={'th':{'class':'centered nodec'}, 'td':{'data-title':'Address 5'}}) postcode = tables.Column(attrs={'th':{'class':'centered nodec'}, 'td':{'data-title':'Postcode'}}) class Meta: model = Address fields = ('address1','address2','address3','address4','address5','postcode',) template_name = 'django_tables2/bootstrap.html' attrs={'id':'addresslist', 'class': 'table table-noborder no-table'} and I pass the data from my view like like this from views.py f = AddressListFilter(request.GET, queryset=Address.objects.all(),request=request) addresstable = AddressTable(f.qs) However, the page needs to allow the user to be able to dynamically add as many extra address records as they wish (which I can use javascript to do this) but I then need to pass the entire table, complete with additional address records, back to django for processing when the user hits the submit button within the form. From what I can gather I should be using a django formset to achieve this … -
How to keep the API running and also Consume Pika (RabbitMQ) parallelly
I have a set of API endpoints serving in the Django app. But I also want to consume a queue(from Pika, a message broker) and execute a function when there is a message in the queue. If I consume a queue, it is blocking the thread and API stops serving. I'm not sure how to achieve this. Do I have to use [background tasks][1] or use Multi-Threading to create a new thread and use it to consume? Any sample code to achieve this is much appreciated.

How do I properly implement Django formsets with a CreateView ( Class Based View )?
And thanks in advance for any suggestions. I have been playing around with how to properly implement formsets with a CreateView for a couple of days and I'm stuck. Here is my code. My Models: class Team(models.Model): team_name = models.CharField(max_length=264,null=False,blank=False) class Player(models.Model): player_name = models.CharField(max_length=264,null=False,blank=False) team = models.ForeignKey(Team,null=True,on_delete=models.CASCADE) My View: class CreateTeamView(LoginRequiredMixin,CreateView): model = Team form_class = CreateTeamForm template_name = 'create_team.html' def get_context_data(self, **kwargs): context = super(CreateTeamView, self).get_context_data(**kwargs) if self.request.POST: context['new_player'] = NewPlayerFormSet(self.request.POST) else: context['nwe_player'] = NewPlayerFormSet() return context def get_form_kwargs(self, *args, **kwargs): kwargs = super(CreateTeamView, self).get_form_kwargs() kwargs['user'] = self.request.user return kwargs def form_valid(self, form): context = self.get_context_data() new_player_form = context['new_player'] if new_player_form.is_valid(): self.object = form.save() new_player_form.instance = self.object new_player_form.save() instance = form.save() else: return self.render_to_response(self.get_context_data(form=form)) My Forms: class CreateTeamForm(forms.ModelForm): class Meta: model = Team exclude = [] NewPlayerFormSet = inlineformset_factory(Team, Player, extra=1, fields=['player_name',]) My HTML: <div="players> <div="add_players"> {{ new_player.management_form }} {% for form in new_player %} {{ form.id }} {{ form.player_name }} </div> </div> My form is saving one player, but when I try to update the code to save more than one player with the initial CreateView, it only recognizes the first contact.

How do you format a Django datepicker as ISO 8601?
We need to display dates in ISO 8601 (yyyy-mm-dd) format throughout our Django site. The dates that we are getting from the database show correctly, however date pickers do not. When I run the django test server in ubuntu, the datepicker appears to use the locale that the OS is set to. When I run the same code in Windows, it uses dd/mm/yyyy. The various input_formats args appear to be getting overridden somehow, even though I have set them everywhere I can find. Is it possible to force datepickers to display yyyy-mm-dd regardless of client settings? If so, how? Here is the code we have so far. forms.py ... class DateInput(forms.DateInput): input_type = "date" input_formats = ["%Y-%m-%d"] options = { "format": "%Y-%m-%d", "autoclose": True } class RegistrationForm(forms.Form): full_name = forms.CharField(max_length=255, required=True) preferred_name = forms.CharField(max_length=255, required=False) email = forms.EmailField(required=True) password = forms.CharField( max_length=255, required=True, widget=forms.PasswordInput, help_text=password_validation.password_validators_help_text_html(), ) birth_date = forms.DateField(required=True, widget=DateInput, input_formats=["%Y-%m-%d"]) ... settings.py ...

How to test Django messages for a Class Based FormView?
I am struggling to find the proper way to test a FormView. I would like to check if the message (generated through django.contrib.messages) is rendered when the user is not authenticated. I have already read about RequestFactory, Client, Mock, Middleware and I was not able to implement this test in CBV FormView. The problem is not about authenticating user particularly, I want to use the logic in other fields also to test other messages. Here is my code: View: class MyView(FormView): form_class = MyForm template_name = 'app/welcome_template.html' def form_valid(self, form): form_data = form.cleaned_data auth = LDAPBackend() user = auth.authenticate(self.request, username=form_data['login_field'], password=form_data['password_field']) if user: return super(MyView, self).form_valid(form) else: messages.add_message(self.request, messages.WARNING, 'some warning' + str(form_data['other_field'])) return self.form_invalid(form) Form: class MyForm(forms.Form): login_field = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'Login', 'class': 'form-control form-control-sm'}), label='Login:', max_length=20) password_field = forms.CharField(widget=forms.PasswordInput(attrs={'placeholder': 'Password', 'class': 'form-control form-control-sm'}), label='Password:', max_length=20) other_field = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'Select ...', 'class': 'form-control form-control-sm', 'max': '99999999'}), label='Other:') Template: <form autocomplete="off" onsubmit="$('#ModalCenter').modal({backdrop: 'static', keyboard: false})" action="." target="_top" method="post"> {% csrf_token %} <div class="row"> <div> {% if messages %} {% for message in messages %} <div class="alert {% if message.tags %}alert-{{ message.tags }}{% endif %}" role="alert">{{ message }}</div> {% endfor %} {% endif %} </div> <div class="form-group mt-2"> {{ form.login_field.label_tag }} {{ … -
Django Form and two forms with foreign key

Python / Django - Generating API Documentation - Not using Django Rest
I am working on a Django project that does not use Django Rest On top of this code base I am trying to build a framework to autogenerate swagger documentation From this S.O. Post I am able to get the available Urls: from django.urls import get_resolver urls = get_resolver().reverse_dict urls is a MultiValueDict, here are the first few items in the Dict: MultiValueDict: { <function create_demo at 0x10f6a3820>: [( [('api/v1/create-demo', [])], 'api/v1//create\\-demo$', {}, {} )], 'create_demo': [( [('api/v1/create-demo', [])], 'api/v1/create\\-demo$', {}, {} )], <function users_detail at 0x10f67d280>: [( [('api/v1/users/users/%(user_id)s', ['user_id'])], 'api/v1/users/users/(?P<user_id>[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12})$', {}, {'user_id': <django.urls.converters.UUIDConverter object at 0x10bc3c6a0>} )], 'users_detail': [( [('api/v1/users/users/%(user_id)s', ['user_id'])], 'api/v1/users/users/(?P<user_id>[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12})$', {}, {'user_id': <django.urls.converters.UUIDConverter object at 0x10bc3c6a0>} )] It appears the keys for this dict are a reference to a view function, followed by the url "name" for that function, and the values are lists containing the relative url path and params. My thought is to loop through each function reference and create an entry for the swagger doc. Inside each view function, I will define vars named RequestSchema and ResponseSchema. Ideally I can access those vars, from the function reference, and add that data to the swagger doc as well. The goal is to have documentation that … -

Mozilla Django OpenID Logout does not revoke token
I've been working to integrate a django app with mozilla-django-oidc and I can't seem to figure out how to log out of the thing correctly. On my main page I have <form action="{% url 'oidc_logout' %}" method="post"> {% csrf_token %} <input type="submit" value="logout"> which provides the logout assuming a user is logged in. Logging in seems to work well enough. In my settings I'm providing the logout configurations OIDC_OP_LOGOUT_ENDPOINT = cfgs.get("LOGOUT_ENDPOINT") OIDC_OP_LOGOUT_METHOD = "test_app_2.openid.logout" LOGOUT_REDIRECT_URL = reverse('post-logout') POST_LOGOUT_URL = cfgs.get("LOGOUT_REDIRECT") Which are my okta oidc logout endpoint, the method that I wrote to create the correct logout url and logout redirect. I created a POST_LOGOUT_URL variable so I can access the post-logout url elsewhere. openid.logout looks like this def logout(request): id_token = str(request.COOKIES['csrftoken']) logout_request = \ f'{settings.OIDC_OP_LOGOUT_ENDPOINT}?id_token_hint={id_token}' \ f'&post_logout_redirect_uri={settings.POST_LOGOUT_URL}' return logout_request Which is the correct logout url configuration for oidc. I've tested all this through a flask app and it all works just fine. Why don't I just use flask? It's a long story. I'd rather use Django... In my views.py I have class LogoutView(OIDCLogoutView): def get(self, request): return self.post(request) Which I confess to have grabbed from another post and I'm not entirely sure how it works with my urls … -

Django DRF - jwt vs simplejwt
I have been ramping up on Django Rest Framework and JWT authentication through tutorials that point to django-rest-framework-jwt but while researching how to customize JWT validation, realized that there is a newer implementation django-rest-framework-simplejwt. The older jwt package does not have a commit since 2017 but simple-jwt is actively maintained and developed, and from what I can find, has better security features. It is also the recommended link in the DRF documentation. I could not find a relevant post on S/O but I found that JoelGoh92 in this git issue summarizes the problem well: 1. In most JWT implementations, an access token + a refresh token is returned. Otherwise the other option, if only a single token is desired, is the sliding token approach. With simple-jwt, the jwt can be configured to either of these implementations, whichever is required. 2. With the current django-rest-framework-jwt supported by rest-auth, the only approach available is similar to the sliding token approach, except that it has no way to blacklist a previously generated jwt token, e.g. by logout on user end. On the other hand, simple-jwt provides a way to perform this blacklisting of invalid tokens. I'm curious to know whether the lack of … -

How do i mock patch a nested method call
So this is quite a 'complex' test case i want to tackle. I have a Django Model, named Store and that store has many methods and fields.

My code: from django.db.models.signals import post_save, pre_save from django.dispatch import receiver from .models import PostImages #signals.py @receiver(pre_save, sender=PostImages) def delete_file_on_change_extension(sender, instance, **kwargs): print('test') #I see nothing in console #Do something... #models.py class PostImages(models.Model): post_id = models.ForeignKey(Post, on_delete=models.CASCADE) image = models.ImageField(upload_to=user_directory_path, null=True, blank=False) Also, it appeared to work when I put signal code in models.py but i could not get it further because it caused mistakes like django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet. -

django framework can't create authentication token in google cloud
I can't create a token for an user manually throught django admin site (https://admin/). I have built an user accounts on a django framework allocated in google cloud server, as a GAE app. In order to add user accounts I use a third-party app for django called "rest_framework", the problem comes when I try to create a token for a created user in admin site, error 500 appear and no idea how to find the problem.

Django benchmark
For my research, I am trying to benchmark Django framework capacity. I am running the server in my own pc which has Intel core i7 processor with 12 core. If I run django with the builin server, it can server, it can server ~3000 request/30s.(HTML is just a "hello world" page). I tried to run Django with Gunicorn. But to my surprise, it does not increase the server capacity. Even if I use 24 worker process, it still can serve ~3100 requests/30s. Does this number seem right? Because compared to other languages, it seems very low. I want to make sure if I am doing it right.
