No Leasson matches the given query. Django
The project structure is as follows: Category: Subcategory: Object. implemented the system next-prev(cat-sub-obj) with difficulty. how can i optimize this code when an object ends up in a subcategory.

Django channels not recalling old messages from channel
I am using Django channels to create a chat app. When the chat page is refreshed, the past messages disappear. Also, when I reconnect to the channel, the old messages do not show up. Everything else seems to work fine, messages can be sent and received by the other user, message data is being saved into the database for each specific channel.

Django Html Raise ValidationError
In my models.py I have: class Post(models.Model): res_person_1 = models.TextField(max_length=40, verbose_name="User") When I load form I run script: $("#id_res_person_1").replaceWith("<select name='res_person_1' id='id_res_person_1' class='form-control' required></select>") $("#id_res_person_1").append("<option>" + '---------' + "</option>") //append options where I create dropdown menu and fill it with users from DB. Problem is, in my models.py and when I run script, I put that field as required. On all other required fields in the form, when I submit, I get error 'Required field', but never on that one. How can I raise an error or show any kind of message to tell the user that he should select something from the dropdown menu. So far I tried (but it did not work): def clean_res_person_1(self): if self.res_person_1 == '' or self.res_person_1 == '---------': raise forms.ValidationError("self.fields['res_person_1'].error_messages['invalid']") return self.cleaned_data -
For each item update database
I'm a total beginner with Python/Django and trying to understand why this isn't working. I have a function that contains a for loop, doing some logic and then updating a model. but when I have more than 1 item in the loop I get a UNIQUE constraint failed: app_token.token_name error. So I think I'm misunderstanding how the loop is working? function tokens = Token.objects.all() for item in tokens: if item.token_contract_address is not None: token = Token.objects.get(pk=item.id) parameters = { 'address':token.token_contract_address } session = Session() session.headers.update(headers) response = session.get(url, params=parameters) resp = json.loads(response.text) token_id = (resp['data'][next(iter(resp['data']))]['id']) logo = (resp['data'][next(iter(resp['data']))]['logo']) url = 'https://pro-api.coinmarketcap.com/v1/cryptocurrency/quotes/latest' parameters = { 'id':token_id } session = Session() session.headers.update(headers) response = session.get(url, params=parameters) id = str(token_id) price = (json.loads(response.text)['data'][id]['quote']['USD']['price']) market_cap = (json.loads(response.text)['data'][id]['quote']['USD']['market_cap']) change = (json.loads(response.text)['data'][id]['quote']['USD']['percent_change_24h']) r = Token.objects.update(token_capture_date = formatedDate, token_price = price, token_name=item.token_name ) I'm expecting the this Token.objects.update(token_capture_date = formatedDate, token_price = price, token_name=item.token_name ) to update the model based on the item loop? The model is very simple: class Token(models.Model): token_name = models.CharField(max_length=50, blank=False, unique=True) token_slug = models.CharField(max_length=50, blank=True,null=True) token_price = models.FloatField(blank=True,null=True) token_capture_date = models.DateField(blank=True,null=True) token_contract_address = models.CharField(max_length=50, blank=True,null=True) def __str__(self): return str(self.token_name) I'm using the update on the objects and have tried removing the token_name, … -
Apache2: 'AH01630: client denied by server configuration' with referer?
I'm trying to setup a django website but for some reason when I try to access the admin page it shows up without an CSS, I dug a bit further and ensured that my file permissions where correct by just making the entire project directory accessible to everyone chmod -R 777 ./survey_server But it still just isn't working for me for some reason, I'm not sure what's going on. I've checked, rechecked, and triple checked my apache config file to no avail. This is my config file: <VirtualHost *:80> # The ServerName directive sets the request scheme, hostname and port that # the server uses to identify itself. This is used when creating # redirection URLs. In the context of virtual hosts, the ServerName # specifies what hostname must appear in the request's Host: header to # match this virtual host.

Faster way than .csv to upload data into Django app
Right now I copy a whole table from a website, paste it into a cell on an excel spreadsheet and it formats it into a .csv file. After the .csv is made I upload the file into my database via a Django app. I also have a model form if I wanted to enter the data manually. What I was wondering is if there is a way to skip a step to make the process faster. Maybe copy the table from the web and paste it into a form cell and it gets formatted like excel does. Any tips or ideas are greatly appreciated. -
accessing 2 foreign key fields at the same time in django serializers
I have the following models in my django rest framework project. in this project there are products and they have producers and importers. # models.py class Product(models.Model): name = models.CharField(max_length=255) producer = models.ManyToManyField(Company, related_name='producer') importer = models.ManyToManyField(Company, related_name='importer') class Company(models.Model): name = models.CharField(max_length=255) I need to make an API which retrieves an instance of the "Company" model and gives me a list of the products they have produced and another list for the products that they have imported Now I know to do this with only one manytomany field, I can do the following: class CompanyRetrieveSerializer(serializers.ModelSerializer): class ProductSerializer(serializers.ModelSerializer): class Meta: model = Product fields = ('name',) product_set = ProductSerializer(read_only=True, many=True,) class Meta: model = Company fields = '__all__' but since there are two fields in the product model that reference the company model, this doesn't work. Is there any way to fix this issue? -
Why isn't my javascript not working with django
I am a beginner in django. I have no problem with the back-end but my front-end has some problem with javascript (specifically addEventListener doesn't work). I've tried everything from adding External js to adding internal js nothing seems to work. But the js connect with django and its being loaded, but the function doesn't work and no error seems to log in the console. It is just a click function, which should toggle a classname in html while clicked. By the way I'm inheriting my nav file. i hope that doesn't cause any problem. My internal js file: <script type="text/javascript"> // EVENT LISTENER FOR NAV FUNCTION let nav_btn = document.querySelector('.user-pr') nav_btn.addEventListener('click', navfunc) function navfunc() { nav_btn.classList.toggle('active') console.log("click") } </script> My Settings.py file (Static Config): STATIC_URL = '/static/' STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static'),] STATIC_ROOT = os.path.join(BASE_DIR, 'Assets') MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') I've checked StackOverflow for similar questions, but nothing match my scenario. -

How to use proxy with vite (vue frontend) and django rest framework
So, you know when you access a view with django rest api on the browser, you get an html page, and when you send something like an ajax request, you get the json? I'm trying to figure out how to mess with the proxy setting for vite, but I can't find a single decent documentation around it. I want to redirect '/' to 'http://localhost:8000/api', but there's really weird behavior going on. If I do this: //vite.config.js export default defineConfig({ plugins: [vue()], server: { proxy: { '/api': { target: 'http://localhost:8000', changeOrigin: true, rewrite: (path) => { console.log(path); return path.replace('/^\/api/', '') } } } } }) //todo-component.vue export default { data() { return { todos: [] } }, components: { TodoElement }, beforeCreate() { this.axios.get('/').then((response) => { this.todos = response.data }) .catch((e) => { console.error(e) }) } } and make requests using '/api', it works as expected.

Django CBV template ignores the override
First, settings.py set url conf: ROOT_URLCONF = "myproject.urls" , and INSTALLED_APPS includes: "myproject.apps.accounts", , which, in turn, has its urls.py set up with: app_name = "accounts" and path("login/", auth_views.LoginView.as_view(template_name="accounts/login.html", form_class=UserLoginForm), name="login"), manage.py check doesn't report any problems, and yet both routes don't work, though But browser reports on route of :accounts/login' reports: TemplateDoesNotExist at /accounts/login/ registration/login.html , where the name it misses is not the one I've put in template_name. I see this in the docs: template_name: The name of a template to display for the view used to log the user in. Defaults to registration/login.html. , which is why I'm overriding, right?... What am I doing wrong? Thanks! -
