Logging in with e-mail as ldapUser in Django

Formsets validate_min is not working properlly
I have a formset with multiple forms: PodFormSet = forms.inlineformset_factory(parent_model=PodP, model=Prod, form=PofModelForm, min_num=1, max_num=4,validate_min=True, extra=3) The issues is that validate_min is not working properly: If the user complete another form than the first one, validate_min doesn't work, say is invalid, which is not, because at least a form is completed but not the first one. How can I override/fix this behavior ? -
How to serve user uploaded images with Django on Heroku in production
In my website an user can upload images. This works fine in development when DEBUG=True, but if I set it to False, the images give error "Not found". I understand that the images disappear after 30 minutes of inactivity, but for me they aren't working at all. I have Whitenoise installed on my settings.py middleware and on requirements.txt. On settings.py I also have these lines: MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') STATIC_URL = '/static/' STATICFILES_DIRS = ( os.path.join(BASE_DIR, 'static'), ) STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') And on urls.py I have this: if settings.DEBUG: urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) The user uploads the files to an ImageField. What do I have to change to make the user uploaded images also work on production? As the tile says, I'm deploying the project to Heroku. -

How to get userprofile in django 2.0
I read a few post already, but I couldn't find what I was looking for. I'm trying to figure out how to get the UserProfile of a user. I created a one to one field relationship when I create the User Profile. I thought I could just query the UserProfile as is, but I can't get it to work. def profile_edit(request): user = UserProfile.objects.get(user=request.user) return render(request, 'medium/profile_edit.html', {'user_profile_form': form, 'current_user': user}) Any thoughts? Here's my models.py and views models.py class UserProfile(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE,) bio = models.TextField(blank=True) avatar = models.ImageField(upload_to='avatars', blank=True) views.py def register_user(request): registered = False if request.method == 'POST': user_form = UserForm(data=request.POST) user_profile_form = UserProfileForm(data=request.POST) if user_form.is_valid() and user_profile_form.is_valid(): new_user = user_form.save() new_user.set_password(new_user.password) new_user.save() new_user_profile = user_profile_form.save(commit=False) new_user_profile.user = new_user if 'avatar' in request.FILES: new_user_profile.avatar = request.FILES['avatar'] new_user_profile.save() registered = True else: print(user_form.errors, user_profile_form.errors) else: user_form = UserForm() user_profile_form = UserProfileForm() return render(request, 'medium/registration.html', { 'user_form': user_form, 'user_profile_form': user_profile_form, 'registered': registered }) -

How do you find the InlineModelAdmin from the admin context data?

How do I pass user_id into a Django method
I need to pass user_id (or a User object that will resolve to user_id) into a function - from both templates and other backend functions. The purpose is to first check if a token exists for the user and if not, then to appropriately call an external API to generate a token. My question is, how do I pass the user_id into the method? Django doesn't appear to have a clear user_id method in the User object and using Django auth I can't set username as the ForeignKey. class Token(models.Model): user_id = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) provider_id = models.ForeignKey(Providers, unique=False, on_delete=models.DO_NOTHING) access_token = models.TextField() refresh_token = models.TextField() r_lasttime = models.DateTimeField expires_in = models.IntegerField token_type = models.TextField() @classmethod #check if a user / provider combination exists def token_exists(cls, user_id, provider_id): return cls.objects.filter(user_id=user_id,provider_id=provider_id).exists() @classmethod def new_token(cls, provider_id, user_id, access_code): # use to acquire a new access token and update it in the database # requires the front end to have already been provided an authorisation token called access_code # determine if the user / provider combination already exist if Token.token_exists(user_id, provider_id) == True: status = {'code': 400, 'desc': 'User/provider combination already exist. Use refresh instead'} return (status) # the user / provider combination does … -

Django form not saving inputs- refreshes upon submission
I am trying to create a website with two dropdown menus: Department and Course Number. The data for the dropdown menus comes from the "courses" table of my SQL database. Right now my website initializes properly and shows the correct options in the dropdown menus. However, when the user selects an option within the dropdown menus and submits their choices, the website reloads as a blank slate so their selections are not being saved or processed. The error lies somewhere in the CourseForm form because I have another form (Working_Form) that is created in a different way but works perfectly. What is wrong with CourseForm/its associated models? models.py from django.db import models class Dept(models.Model): dept = models.CharField(max_length=255, db_column = 'dept') class Meta: managed = False db_table = 'courses' def __str__(self): return self.dept class Course_num(models.Model): course_num = models.CharField(max_length=255, db_column = 'course_number') class Meta: managed = False db_table = 'courses' def __str__(self): return self.course_num forms.py from django import forms from django_select2.forms import ModelSelect2Widget from .models import Dept, Course_num class CourseForm(forms.Form): dept = forms.ModelChoiceField( queryset=Dept.objects.distinct().\ order_by('dept').exclude(dept__isnull=True), required=False, empty_label="No preference", label=u"Department") course_num = forms.ModelChoiceField( queryset=Course_num.objects.distinct().\ order_by('course_num').exclude(course_num__isnull=True), required=False, empty_label="No preference", label=u"Course Number") views.py from django.shortcuts import render from django import forms from .models import Dept, …
