Is there a way to pass URL template tag from database to template in Django?
I apologize if my question is poorly worded. Basically, I am making a database of fictional characters and in the database, I have a biography of the character. I would like to link to other characters using the {% url 'viewname' otherchar.slug %} method. However, all I get back from the database is literally that line of code. I understand it may not be possible, but is there a way to get Django to see that line and turn it into an absolute URL like it would if I manually added the URL tag into the page? Something to add - I am using TinyMCE so the content in the database is being saved with HTML - I want to be able to save external links, subheadings, and whatnot, which is why I chose to use TinyMCE and its HTML field. models.py class Character(models.Model): name = models.CharField(max_length = 255) faction = models.IntegerField(default = 0) rankIMG = models.ImageField(upload_to = 'rankIMG/', blank = True) department = models.IntegerField(default = 0) content = HTMLField() slug = models.SlugField() views.py class CharacterFull(DetailView): model = Character context_object_name = 'character' def get_context_data(self, **kwargs): context = super(CharacterFull, self).get_context_data(**kwargs) context['factionDict'] = charFaction context['deptDict'] = charDepartment return context urls.py app_name = … -
Retrieve Access/Refresh token with username/password from Django REST API
I am trying to build an application on Google AppScript that should communicate with a third-party API. This API uses Django REST Framework and JWT. I have a username and password to access domain/api/token, login and get the access and refresh tokens. I can do this manually but I would like to implement some sort of a login on my application side that will get a new access/refresh (if needed) token from the API so it can start fetching data from the service. My question is, how can I structure the POST request to retrieve the access/refresh token pairs so I can continue with the next requests? This is what I'm trying to do: var formData = { 'async': true, 'crossDomain': true, 'method': 'POST', 'headers': { 'Content-Type': 'application/json', 'username': 'user', 'password': 'secretpassword' }, 'muteHttpExceptions': true } var url = 'domain/api/token' var res = UrlFetchApp.fetch(url, formData); -
Fetching results from a method in Django
My Django app ('crisismode') has two models : Events and Actions I would like to display events and actions related to these events. For each event, I only want to display active actions, so I used a method (activactions). How to prefetch these actions ? class Event(models.Model): description = models.CharField(max_length=1000, blank=True) active = models.BooleanField(default=True) def activeactions(self): actions = Action.objects.filter(event=self, active=True) if actions: return Action.objects.filter(event=self, active=True) else: return None class Action(models.Model): description = models.CharField(max_length=1000) active = models.BooleanField(default=True) event = models.ForeignKey(Event, on_delete=models.SET_NULL, related_name="actionsforevent", null=True, blank=True) I perform the following query: events = Event.objects.filter(crisis=crisis, active=True).prefetch_related('actionsforevent') But django-debug-toolbar shows me that there are multiple queries for it : FROM "crisismode_action" WHERE ("crisismode_action"."active" = true AND "crisismode_action"."event_id" = 323) ORDER BY "crisismode_action"."order" ASC, "crisismode_action"."id" ASC 10 similar queries. Duplicated 2 times. -
Why isn't my image loaded/fetched from AWS RDS in my React application?
So I have my Django Rest Framework deployed with AWS EC2. I also have RDS instance for saving images. Then I have a React application deployed that fetches some objects(including the images) from DRF. Now when I load the page, all the other fields(?) of each object are loaded but the image. I see 404 Not Found error, and have no idea what is going on. I have console.loged and saw the object myself, and the url of the image is just fine. http://ec2-some-address.ap-northeast-2.compute.amazonaws.com/media/None/myimage.jpg. the media/None/ directory is as expected. Any idea? Thanks a lot in advance :) -
Problem with mixing Detail View and Form Mixin django

Django Find custom user with the same value of JSONfield
I have a django application, where I use custom user model. Model has a JSONfield, which represents which programming languages do this user use. It looks like this: {"langs": [1, 2, 3, 4]} These numbers are ID's of Language DB model. So is it possible to find users in DB, who have 1 or more same language as the current user. I want to get an array with custom user objects sorted by number of matching langs. Sorry if this question is too stupid. -
compress.js made the CACHE directoly under uwsgi not nginx
I am using Django Compressor on nginx & uwsgi I have each docker container for nginx & uwsgi I copied static folder to nginx:/static and others to uwsgi:/myapp/ in advance.

implement dynamic database models for messenger web app django
i want to create a messenger webapp in django in which a sql table will be created which will only store the conversation of two user . the naive approach is to create a table for messages which will store info like id,message_text,sender,reciever etc. but in case of large user this will not be efficient. if we allot a conversation between two user in a single table then it will reduce the searching time. i dont know how to implement dynamic models . Is there any better approach for this problem? -

How to get base64 image through selenium (2captcha)?
I need to get the base64 from a captcha image to pass it to a method that solves it. The thing is, how do I manage to do that? This my view but so far I only get an exception from the resolve_simple_captcha function that says: "Error getting the captcha id". The function needs image_base64 to work.

Want to first save user profile data and then automatically create user
This application is for a school where the admin(through django admin) can upload the student's data and based on that, a user is created ( username is ID and password is dd/mm/yy).Basically removing the need for all the students to register themselves on the platform. I've seen videos where signals are used to create profile from user using post_save() but to create user from profile I can't use that since profile editing is also allowed which will trigger post_save() and try to create a user, even though one already exists for that profile. Any help will be appreciated. Thank you -
How to track monthly subscription usage of user in django?
I have the scenario where I have three models: Subscription Model User Model (Has Subscription Model ForeignKey) Match Model (Has User Model ForeignKey) Users can choose to sign up for 6 month/ 12 month/ 18 month subscriptions where they can have a maximum of 10 matches PER MONTH. Users may start the subscription on any given date of the month. My question is how do I track how many matches are assigned to the user in a given month(with the first date of the month being the date he signed up on)? How do I reset the number of matches back to 10 after every month finishes? -
Django HTML page is showing template code for form as text
I'm pretty new to Django (technically this is written in Django-Mako-Plus), and I'm trying to display a form on an HTML page, but it is displaying the template code as text and I can't figure out why. I've set up my form in forms.py: class FilterForm(forms.Form): def init(self): self.fields['keywords'] = forms.CharField(label='Keywords') self.fields['hours'] = forms.CharField(label='Training Hours') self.fields['instructor'] = forms.CharField(label='Instructor') self.fields['subject'] = forms.CharField(label='Course Subject') self.fields['agegroup'] = forms.CharField(label='Target Age Group') I've added the form to my context variable in the view: from django import forms from .forms import FilterForm @view_function def process_request(request, cat_id:int = None, pnum:int = 1): currentDate = datetime.today() currentYear = currentDate.year #allcourses = hmod.Courses.objects.all() allcourses = hmod.Courses.objects.only("courseid", "coursetitle", "coursephoto", "coursedescription") form = FilterForm() context = { # sent to index.html: 'current_year': currentYear, 'allcourses': allcourses, 'form': form, } return request.dmp.render('courselist.html', context) And I've tried to display the form on the page in the template. <form action="/your-name/" method="post"> {% csrf_token %} {{ form.as_p }} <input type="submit" value="Submit"> </form> The problem is, when I go to the page, instead of showing the form, {% csrf_token %} and {{ form.as_p }} show up as text on the page.

Is there a dynamic web framework I could use in R that's comparable to Django

How to add exception to a dictionary if the result is useless for my data?
So I have this code to get the id of a person and check if the person exists in a database. The code works but I forgot to add an exception for people who exist but their id is not a "useful" one. I tried adding an exception to my code that says: except cuit == "CUIL": print("it's not a cuit") But this is ignored and I get the data anyway even though I don't want it. So what's a better way of doing it? The info is in response["persona"]["tipoClave"] This gives two results: "CUIL" (not useful) and "CUIT" (useful). So how do I prevent the useless ids to be passed as useful? This is the code: class ConstanciaInscripcion(FormView): def get(self, request): return render(request, 'app/constancia-inscripcion.html') def post(self,request): form = MonotributoForm(request.POST) email = request.POST['Email'] #Verificar cuit en padron13 una vez que es ingresado cuit_r = int(request.POST["CUIT"]) response = get_persona(cuit_r) try: nombre = response["persona"]["nombre"] apellido = response["persona"]["apellido"] cuit = response["persona"]["tipoClave"] except KeyError: nombre, apellido = None, None print("El CUIT ingresado es incorrecto") except TypeError: nombre, apellido = None, None print("El CUIT ingresado es incorrecto") except cuit == "CUIL": print("it's not a cuit") else: print(nombre, apellido) if form.is_valid(): cuit = form.cleaned_data.get('CUIT') email = … -

How to change the template of password-reset-email properly Django
This line of code is responsible from sending an email which contains a password reset link. path('accounts/password-reset/', auth_views.PasswordResetView.as_view(), name='password_reset'), However the email looks completely dull and it is difficult to distinguish important parts while reading. To attract the attention of the user and direct them better I would like to add style to this body of email. It is possible to add custom template to the email by these lines: ... path('accounts/', include('django.contrib.auth.urls')), path('accounts/password-reset/', auth_views.PasswordResetView.as_view(html_email_template_name='registration/password_reset_email.html'), name='password_reset'), ... The thing is the reset-link inside the email consists of a uidb64 value and a token, such as: localhost:8000/password-reset/calculated_uidb64/calculated_token What is the proper way to pass these values to the custom template of password_reset_email.html? -
