django template statement if != Null doesn't work
I got problem with template tag {% if ... in ... %}. I'm trying to write statements if object don't exist ( equal Null ) then don't display anything. My model got few fields for links to SOcial Media like instagram, facebook, twitter etc. and not every company got every social media as we know. The problem is that those If statements doesn't work as they should (I checked django documentation), for example if company have added links to all social medias (twitter,fb,instagram,linkedin,website) it should display images with links to them. But if company have not added any link to social medias or website, it shouldnt display images. I don't know why those statements doesn't work About images, if I remove the loop {% for ... %} {% endfor %} then it is displaying all images even if company has not associated any links so this if statements also doesnt work then comp_view.html <div class="social-media"> {% for brand in brands % {% if brand.website != None %} <a class="" href="{{ brand.website }}"> <img src="/static/icons/website.png"> </a> {% endif %} {% if brand.facebook != None %} <a class="" href="{{ brand.facebook }}"> <img src="/static/icons/facebook.png"> </a> {% endif %} {% if brand.instagram != None … -
Django - importing view from Dependency
I'm trying to use this library since i want to add 2FA Auth to my project. In order to integrate the module in my project, i need to import their views to my urls.py file, right? I tried to import SetupView, but i'm getting this error: module 'allauth_2fa.views' has no attribute 'homepage'. Here is what i understood: it looks like if i import a view from the dependency, it will only read those views from the dependency but not my own views declared on views.py. from django.urls import path from . import views from django.conf.urls import url, include from django.conf.urls import url from allauth_2fa import views app_name = "main" urlpatterns = [ path("setup/", views.TwoFactorSetup.as_view(), name="setup"), path("", views.homepage, name="homepage"), path("register/", views.register, name="register"), path("logout/", views.logout_request, name="logout"), path("login/", views.login_request, name="login"), ] Extra: SetupView will generate the page required to enable the 2FA authentication, that's why i need it. Later i will also import the other views required to have my two factor authentication fully running -
Django formtools buisness logic between forms
I am trying to implement OTP add feature in django-formtools and pyotp.(i know there is a library to do that, but I want to do it in house.) The workflow is like this. Enter captcha -> pass? -> show otp secret -> user enters generated otp code -> does the code matches with the secret? -> save secret to user model. I first made two forms, # forms.py class OTPUpdateForm1(forms.Form): captcha = CaptchaField() class OTPUpdateForm2(OTPForm): otp = forms.CharField() def clean(self): # validate otp code and then I created a formview. # views.py class NewOtpWizard(SessionWizardView): form_list = [OTPUpdateForm1, OTPUpdateForm2] success_url = reverse_lazy('otp-update') def get_template_names(self): return f'profile/editotp/step{self.steps.step}.html' def done(self, form_list, **kwargs): self.request.user.profile.save_totp_secret(data_for_step1['totp_secret']) return HttpResponseRedirect(success_url) So, I need a buisness logic code between the two forms, that is to create otp secret to verify the otp with the secret save the otp secret My questions is Where do you put the code to create otp secret? I overrided get_context_data but I think it's not the right place. It's done even when the user fails to verify the otp, resulting in a new otp secret. How do you pass the generated otp secret to OTPUpdateForm2 so that it can validate and raise ValidationError when … -
In a forms of an inlineformset how can I know which are my default form fields and which are the ones added by Django?
I have a specific formset (inlineformset), and I want to make some customization regarding the default design. I loop thru it this way: {% for form in formset %} <div class="ct-formset"> {% if form.errors %}<div>{{ form.errors }}</div>{% endif %} {% for field in form %}{{ field }}{% endfor %} {% endfor %} For each form Django add two other fields the Foreign key field and the Delete Field. Because I want to use the same code for multiple formsets, In the loop I don't request the field by name I need to know in the: {% for field in form %}{{ field }}{% endfor %} How can I know which are my default form fields and which are the ones added by Django ? -
How to pass an object between views in Django
I have the following model for my students to upload their tasks to an application that I am creating, but I have a problem, I need to pass an instance of the model between views, but since it is not serializable, I can not save it in a session attribute. Keep in mind that in one view I create the object without saving it in the database and in the other I perform operations with the object and finally I save it. Any idea how I can do this? class Homework(models.Model): code = models.AutoField(primary_key=True) student = models.ForeignKey('Student', on_delete=models.PROTECT) title = models.CharField(unique=True, max_length=100) attached_file = models.FileField(upload_to='files/homeworks/', validators=[validate_file_size], storage=gd_storage) -
How can I log a Django user into WooCommerce without prompting?
My workflow takes the user from a Django web application to a WooCommerce store. For example, they fill in example.com/register and are taken to store.com/checkout. Both applications are backed by the same LDAP database, so at the moment I prompt the user to enter their credentials a second time. This is functional, but not the greatest UX. How can I transport them from the Django to store domain and sign them into the store, without user intervention? (Because the domains are different and I expect third-party cookies to be disabled, I obviously can't generate a cookie for the store domain while still in the Django domain.) -
Allauth Django2 Social Network Login Failure: The domain of this URL isn't included
I've read every SO post on this topic and still no luck. The Facebook login button makes it all the way through directing the user to Facebook, having them enter their credentials and press submit, but then it redirects back to my domain name with an error. I've edited the Allauth template to display Code: {{ auth_error.code }}, Error: {{ auth_error.exception }} which returns Code: unknown Error: Error retrieving access token: b'{"error":{"message":"Can\'t load URL: The domain of this URL isn\'t included in the app\'s domains. To be able to load this URL, add all domains and sub-domains of your app to the App Domains field in your app settings.","type":"OAuthException","code":191,"fbtrace_id":"xxxxxxxx"}}' I've added to Valid OAuth Redirect URIs my domain name and https://www.myapp.com/accounts/facebook/login/callback/ etc but nothing changes. I do notice that the URL when the error is thrown is https://www.myapp.com/accounts/facebook/login/callback/?code=dksjfhskdjhfskdjfskdjhfksjdhfkdsjfhksdjfh(really long code)&state=pEekQctKQlND#_=_ So URI ?code=XXX seems to be tacked onto the URI, not sure if that helps with anything. -
