Use authentication in templates and vue.js together
I have mature Django application that is built with Django-templates for the frontend. Now I want to rewrite part of the application to Vue.js (user's dashboard). That is, I want use the Django-Rest-Framework for the backend and Vue.js for the frontend, but not use Django templates at all. Is it possible to somehow combine the authentication that is used in Django templates in the frontend, written in Vue.js? That is, so that the frontend, written in Vue.js, receives information whether the user is authenticated or not. -
How the change the underlying model for a form in a view?
I have a small Django-app were I want to manage two stock portfolios. I created two tables (SecuritiesSVR and SecuritiesAHT) with the same structure (based on an abstract model). In the url I added an argument 'ptf' : portfolio/str:ptf/change_position I also created a form to update the tables: class SecuritiesUpdateForm(forms.ModelForm): class Meta: model = model is dependent on parameter in url fields = ['opinions', 'remarks'] Now i'm searching for a way to change the underlying model for the form depending on the parameter in the url: def change_position(request, ptf, symbol): if ptf == 'aht': Securities = SecuritiesAHT if ptf == 'svr': Securities = SecuritiesSVR security = Securities.objects.get(pk=symbol) if request.method == 'POST': u_form = SecuritiesUpdateForm(request.POST, request.FILES, instance=security) if u_form.is_valid(): u_form.save() messages.success(request, f'Security has been updated!') return redirect('portfolio:portfolios', ptf=ptf) else: u_form = SecuritiesUpdateForm(instance=security) context = { 'u_form': u_form, 'ptf': ptf } return render(request, 'portfolio/change_position.html', context) Is there a possibility to set in the view the model that the form needs to use? -

Scrapy/Django - PyCharm debugger - can't import model

Django model last modification datetime, how to exclude the influence of some fields?
I use DateTimeField with auto_now=True to store last update datetime: updated_at = models.DateTimeField(auto_now=True) I want to update this datetime for all changes in model exclude some fields. Example model: class MyModel(models.Model): field1 = models.IntegerField() field2 = models.IntegerField() updated_at = models.DateTimeField(auto_now=True) So, i need updated_at field to be updated if something changes in the model, but except changes in field2.

Configure Pycharm Pro for Django
I just got the Pycharm's Pro Student License. I have looked up on the internet on how to configure the settings, however apart from syntax highlighting, nothing much has changed.

domain restriction does not doing anything
Hello I have a simple form where I want to save information. I added the domain restriction in my forms but it still saves emails with other email domains. I am new to django maybe it is an easy task, thanks. models.py from django.db import models class WPGroup(models.Model): name=models.CharField(max_length=128,blank=False) number=models.PositiveIntegerField(blank=False) bolum=models.CharField(max_length=128,blank=False) mail=models.EmailField(max_length=128,blank=False) def __str__(self): return self.name forms.py from django import forms from .models import WPGroup class WPGroupForm(forms.ModelForm): class Meta: model=WPGroup fields=['name','number','bolum','mail'] def clean_email(self): email = self.cleaned_data['mail'] if "@itu.edu.tr" not in email: raise forms.ValidationError("You must include @itu.edu.tr") return email views.py class WPGroupView(generic.CreateView): template_name='wp.html' form=WPGroupForm model=WPGroup fields=['name','mail','bolum','number'] success_url='success/' -
535, b'5.7.8 Username and Password not accepted with G Suite and Django
I'm trying to send email from my G Suite account. I have enabled 2FA and generated an app password that I'm using in my django project. My settings.py file looks like this: EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' DEFAULT_FROM_EMAIL = os.getenv("EMAIL_USER") EMAIL_HOST = 'smtp.gmail.com' EMAIL_USE_TLS = True EMAIL_PORT = 587 EMAIL_HOST_USER = os.getenv("EMAIL_USER") EMAIL_HOST_PASSWORD = os.getenv("EMAIL_PASSWORD") I have set the EMAIL_HOST_PASSWORD as the 16 character generated app password. Why is it still failing? (There is no way to allow "less secure apps" with G Suite if I got 2FA enabled - I'm just redirected to creating an app password, which is what I have done) I just keep getting (535, b'5.7.8 Username and Password not accepted.

No user link in auth section of Django admin

Importing scipy stats makes django time out on AWS elastic benastalk
I have a moderately complex api in Elastic Beanstalk. It uses celery and django. It's driving me crazy that just trying to import scipy stats makes django not be able to return anything. I've checked the instance and there is available memory and cpu. I singed out scipy by elimination, as python won't even return an error. I am running version 3.6 of python, scipy version 1.5.2 . I have a rather long list of libraries installed. Even when not using scipy (just importing it) the script will just not return anything. Commenting the import makes everything work fine. I have tried importing the library on a new development with the same characteristics and it seems to work. Any ideas as to what might be causing this behavior? -- Edit -- It looks like adding the full list of requirements makes the new development have the same problem (even though it is just a default django app that does nothing but show an index.html file). So I am adding the list of libraries. I am guessing one of them is having problems with scipy. aiocontextvars==0.2.2 amqp==2.5.2 asgiref==3.2.4 attrs==19.3.0 awscli==1.18.28 awsebcli==3.17.1 bcrypt==3.1.7 billiard==3.6.3.0 blessed==1.17.2 boto3==1.12.16 botocore==1.14.0 botometer==1.5 cached-property==1.5.1 celery==4.4.2 cement==2.8.2 certifi==2020.4.5.1 … -

matching django url with views using a model slug
my problem is that I can not establish a reverse match, most likely doing something wrong with my url definition (?). Ultimately what I am trying to do is the following: User selects 2 location points which the 'new_pointview' view, saves into a DB. I also define a unique slug which contains location information and save it to the DB via the save() within the model. Then the user should be redirected to a url (pointview view) which uses the slug I created in the previous step i.e /pointview/slug. Here is the code: models.py class Points(models.Model): starting_point_longitude = models.FloatField(null=True) starting_point_latitude = models.FloatField(null=True) ending_point_longitude = models.FloatField(null=True) ending_point_latitude = models.FloatField(null=True) url = models.SlugField(max_length=250, null=True, unique=True, blank=False) def save(self, *args, **kwargs): self.url = 'start_lon-{0}-start_lat-{1}-end_lon-{2}-end_lat-' \ '{3}'.format(self.starting_point_longitude, self.starting_point_latitude, self.ending_point_longitude, self.ending_point_latitude) super(Points, self).save(*args, **kwargs) def get_absolute_url(self): return reverse('pointview', kwargs={'url': self.url}) views.py def pointview(request, url): point = get_object_or_404(Points, url=url) content = {'starting_point_longitude': point.starting_point_longitude, 'starting_point_latitude': point.starting_point_latitude, 'ending_point_longitude': point.ending_point_longitude, 'ending_point_latitude': point.ending_point_latitude} return render(request, 'points.html', {'user_bundle': content}) def new_pointview(request): Points.objects.create( starting_point_longitude=request.POST['starting_point_longitude'], starting_point_latitude=request.POST['starting_point_latitude'], ending_point_longitude=request.POST['ending_point_longitude'], ending_point_latitude=request.POST['ending_point_latitude'], ) points_filtered = Points.objects.filter( starting_point_longitude=request.POST[ 'starting_point_longitude']).filter( starting_point_latitude=request.POST[ 'starting_point_latitude']) unique_url = points_filtered.values()[0]['url'] return redirect('/pointview/{0}/'.format(unique_url)) urls.py urlpatterns = [ path(r'^pointview/(?P<url>[-\w]+)/$', views.pointview, name='pointview'), path('^new_pointview/', views.new_pointview, name='new_pointview'), ] The error: The current path, pointview/start_lon-738949.9146592747-start_lat--153698.8751025315-end_lon-759997.8063993475-end_lat--168467.65638300427/, didn't match any of URL … -

Django : reference to models in view --> Local variable might be referenced before assigment
I have a small Django-app were I want to manage two stock portfolios. I created two tables (SecuritiesSVR and SecuritiesAHT) with the same structure (based on an abstract model).

Creating a linked hashtag in markdown
I'm currently trying to parse markdown in django/python and linkify hashtags. There are some simple solutions to this: for tag in re.findall(r"(#[\d\w\.]+)", markdown): text_tag = tag.replace('#', '') markdown = markdown.replace( tag, f"[{tag}](/blog/?q=%23{text_tag})") This works well enough, but converts everything with a # into a link. Eg: https://example.com/xyz/#section-on-page gets linkified. It also gets linkified if it is currently inside of a link itself. Internal links are also broken as Link get linkified. Here's a comprehensive case: #hello This is an #example of some text with #hash-tags - http://www.example.com/#not-hashtag but dont want the link #hello #goodbye #summer #helloagain #goodbye This is #cool, yes it is #radaf! I like this #tool. [Link](#not-a-hashtag) [Link](https://example/#also-not) <a href="#this-neither">Hai</a> Thanks
