Django POST Question for Hangman Game - Cant Update More Than One Letter
I'm working on a Hangman game using Django and trying to update the correct letters guessed in the word on the page. It seems I can get one letter at a time but not more than one to update the word as the game progresses. Its almost like a new list is initializing each time the function is called. Any suggestions? Here is my code, the 'else' is defaulted off a post request. Any buttons clicked from the keyboard are sent to a function where I handle the POST request, one button at a time. I'm a little unfamiliar working with HTTP requests/responses so any help would be appreciated. else: game_id = int(request.POST['game_id']) letter_guess = request.POST['letter'] game = Game.objects.get(game_id=game_id) game.guess = letter_guess split_answer = game.answer.split() answer1 = split_answer[0] len1 = int(len(game.display1) / 2) word1 = list(range(len1)) for x in range(len1): if answer1[x] == letter_guess: word1[x] = answer1[x] + " " else: word1[x] = "_ " word1 = "".join(word1) game.display1 = word1 game.save() -
Why am i getting "No Such Table" when running SQL query with cursor.execute()?
I am trying to run a simple sql query but i keep getting "Operational Error: No Such Table customers" The code in question is: cursor = connection.cursor() cursor.execute("SELECT * FROM customers") # cursor.festchone() or cursor.fetchall() r = cursor.fetchone() print(r) Whats weird is running a raw SQL query using the code below works and i'm able to iterate through the rows and display in HTML: sql = "SELECT * FROM customers" customer = Customer.objects.raw(sql)[:10] print(customer) print(connection.queries) Also whats weird is the django docs says to add the app name so when adding the app_name network into the 2nd code, i get an error saying no such table: network.customers but the code works if i remember the app name: sql = "SELECT * FROM network.customers" customer = Customer.objects.raw(sql)[:10] print(customer) print(connection.queries) Databases in settings.py: DATABASES = { 'default':{ 'ENGINE': 'django.db.backends.sqlite3', 'NAME': BASE_DIR / 'db.sqlite3', }, 'network_db':{ 'ENGINE': 'django.db.backends.sqlite3', 'NAME': BASE_DIR / 'Network.sqlite3', }, 'simulation_db':{ 'ENGINE': 'django.db.backends.sqlite3', 'NAME': BASE_DIR / 'Simulation.sqlite3', } } Network apps.py: from django.apps import AppConfig class NetworkConfig(AppConfig): default_auto_field = 'django.db.models.BigAutoField' name = 'network' So i'm wondering why is the 2nd code working but the 1st code is not?

Import feed into Django template
I'm trying to import some feed from a website into my blog builded with Django. Into context_processors.py I've created the function belowe: import feedparser def pygisblog_feed(request): url = "https://pygisblog.massimilianomoraca.me/feed.xml" feeder = feedparser.parse(url) for entry in feeder['entries']: title = entry['title'] link = entry['link'] description = entry['summary'] published_at = entry['published'] context = { 'title': title, 'link': link, 'description': description, 'published_at': published_at, } return context In settings I've added the function into context processors list. Now I would like to see the feeds in a template, so: {% for post in pygisblog_feed %} <p>title: {post.title}</p> {% endfor %} But I see a blank page. Probably it happen becouse I can use the for loop template tag only with a queryset. Is possible to convert a list or a dictionary to a queryset? If yes, how? -

Django model's __str__ with seperate fields
I have a model that return's a financial year and a description. Currently the attributes are combined into one value as one field. As you can see, the year 2021 and description test. I can click on the field which brings me to the details page. My code: class Meta: ordering = ['description', 'accounting_year', 'swift_code'] verbose_name_plural = "Extractions" def __str__(self): return f'{self.accounting_year} {self.description}' What I would like to achieve, but can't figure out nor find it online is to split the two fields into separate columns. Thus, 2021 as a column and test as a column. Furthermore, I would like to be able to sort or even filter, because one of the fields is extraction date. Would be great that an admin user could changed the order from newest to oldest and vice versa of just filter on name or date. Any documentation on that? -

Django Formset - each form with different initial value from M2M-through relationship
I have to models which are connected by a M2M-Field realized by another Class ComponentInModule, so that I can add there the extra information, how often a component is in the module. class Module(models.Model): ... component = models.ManyToManyField(Component, through="ComponentInModule") class Component(models.Model): ... class ComponentInModule(models.Model): module = models.ForeignKey(InfrastructureModule, on_delete=models.CASCADE) component = models.ForeignKey(InfrastructureComponent, on_delete=models.CASCADE) amount = models.IntegerField(default=1) Now I am trying to load a Module as a form with its corresponding Components as a formset. class ComponentForm(ModelForm): amount = IntegerField() module = InfrastructureModule.objects.get(id=x) ComponentFormSet = modelformset_factory(Component, form=ComponentForm, extra=0) component_formset = ComponentFormSet(queryset=module.get_components()) As you can see my ComponentForm has the extra field for the amount. The question now is, how can I pass the value of amount to the Formset on creation, so that all forms are initialized with the right value? With a single Form it's no problem, because I can just pass the value to the __init__ function of the form and put it into the amount field self.fields["amount"].initial = amount. I tried passing a list of values to the formset with form_kwargs, but then I got the problem, that in the __init__function I dont know which of the values in the list is the right one right now.

Django DRF + Allauth: OAuth2Error: Error retrieving access token on production build
We are integrating DRF (dj_rest_auth) and allauth with the frontend application based on React. Recently, the social login was added to handle login through LinkedIn, Facebook, Google and GitHub. Everything was working good on localhost with each of the providers. After the staging deployment, I updated the secrets and social applications for a new domain. Generating the URL for social login works fine, the user gets redirected to the provider login page and allowed access to login to our application, but after being redirected back to the frontend page responsible for logging in - it results in an error: (example for LinkedIn, happens for all of the providers) allauth.socialaccount.providers.oauth2.client.OAuth2Error: Error retrieving access token: b'{"error":"invalid_redirect_uri","error_description":"Unable to retrieve access token: appid/redirect uri/code verifier does not match authorization code.

Django admin - how to get a parameter from the url
I'm trying to make a default value in my table via the URL. I try to use the function get_year, but it returns me the first value in Year. For example, I have 2 tables: model.py class Year (models.Model): year = models.IntegerField(primary_key=True, verbose_name='Year') def __str__(self): return str(self.year) class Meta: ordering = ['year'] class RFCSTForm (models.Model): id = models.AutoField(primary_key=True) def get_year(self): selection = Year.objects.values_list('year')[0] return selection year = models.ForeignKey(Year, verbose_name='Year', null=True, blank=True, on_delete=models.CASCADE, default=get_year(Year)) budget_q1 = models.IntegerField(verbose_name='Budget Q1', null=True, blank=True) budget_q2 = models.IntegerField(verbose_name='Budget Q2', null=True, blank=True) budget_q3 = models.IntegerField(verbose_name='Budget Q3', null=True, blank=True) budget_q4 = models.IntegerField(verbose_name='Budget Q4', null=True, blank=True) avi = models.CharField(verbose_name='avi', max_length=200, null=True, blank=True) def __str__(self): return str(self.id) def total_budget(self): return self.budget_q1 + self.budget_q2 + self.budget_q3 + self.budget_q4 class Meta: ordering = ['id'] # unique_together = ('year', 'scenario') verbose_name = "RFCST Form" #Title on the maint page for this table verbose_name_plural = "RFCST Form" #Title for the navbar navigation The url: (if to be more precise, I want part of the URL, '2022') TNX -
Passing Data into Forms Django
Hypothetically; I have a simple system that has a list of choices on a screen. Each item has a button so you can add multiple supplementary items/information alongside the item selected but not change the item selected. Each item has a unique id which I want to pass into the form so that the comment is always associated with the item. I have a model that contains a foreign key that links the comment to the item and the Modelform works but I have to select the item from a drop down and I would like this information to be pre-populated in the form. This seems so simple but I have been going round in circles for days. Any pointers would be greatly appreciated
