And I want to be able to create a drag and drop form one treeview to the other in odrer to link data between the data tables. I tried django-treenode but i can t understand to use it for doing my view. -
Constrain Django model by field value
Consider the following Django model: class Account(models.Model): ACCOUNT_CHOICES = [ ('m', 'Main',), ('s','Secondary') ] user = models.ForeignKey(User) level = models.CharField(max_length=1, choices=ACCOUNT_CHOICES) How can I enforce a database constraint of a maximum of one 'Main' account per user, while still allowing any number of 'Secondary' accounts per user? In a sense, I want unique_together for user and level, but only when the value of level is m. I know that I can manually check on saving, but I would prefer the database to check automatically and raise an IntegrityError when appropriate. -
creating custom profiles for selected user types
1.I have multiple type of users in my project. i have created a single signup page. in the signup page i have option to select the type of user.based on the selection a related profile should be created and the type of user should be logged into their particular profile page..for example..if the type of user selected is student then after signup a student_profile should be created and student should be logged into that.. similar for professional and other user types.I have used django auth user model to create signup.. 2. I have many custom profile forms for each user types and no idea how to integrate it..model is below: what Please don't suggest me this link cz i don't wanna go with this approach since they use a signup for each user type but i have only one signup for every user type.. https://simpleisbetterthancomplex.com/tutorial/2018/01/18/how-to-implement-multiple-user-types-with-django.html user registration in forms.py: class UserRegistrationForm(forms.ModelForm): password = forms.CharField(label='Password', widget=forms.PasswordInput) password2 = forms.CharField(label='Repeat password', widget=forms.PasswordInput) class Meta: model = User fields = ('username', 'first_name', 'email') def clean_password2(self): cd = self.cleaned_data if cd['password'] != cd['password2']: raise forms.ValidationError('Passwords don\'t match.') return cd['password2'] def clean_email(self): email = self.cleaned_data.get('email') username = self.cleaned_data.get('username') if email and User.objects.filter(email=email).exclude(username=username).exists(): raise forms.ValidationError(u'Email addresses … -
Add individual users to Project in Django
I am building a basic project management app using Django, where a Project can have any number of users. How can I create a form to add users one at a time? The default behavior of Django provides multi-select fields for many to many relationships. class Project(models.Model): project_number = models.IntegerField() name = models.CharField(max_length=100) design_manager = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='project_design_manager', null=True, blank=True) permit = models.CharField(max_length=100, blank=True, default='') is_active = models.BooleanField(default=True) users = models.ManyToManyField(settings.AUTH_USER_MODEL, blank=True, related_name='project_users') I want a dynamic field that allows you to add one user at a time. -
Create Extended User Object with Django Rest Auth
I'm using django-rest-auth with django-rest-framework. I have the default API endpoints already generated. They appear like so: api-endpoints: { login: { create(password, [username], [email]) } logout: { list() create() } registration: { verify-email: { create(key) } create(username, password1, password2, [email]) } user: { read() update(username, [first_name], [last_name]) partial_update([username], [first_name], [last_name]) } } Now, I want to use a custom model called UserProfile, which extends the default user via a OneToOneField as shown below: class Account(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) custom_field1 = models.CharField(...) custom_field2... ... The docs state I should create a custom registration serializer. I did some searching around and figured I could try this code as that custom serializer (with cf as an abbreviation for custom_field for this example): class CustomRegisterSerializer(RegisterSerializer): def get_cleaned_data(self): user_dict = super().get_cleaned_data() user_dict["c1"] = self.validated_data.get("cf1", '') user_dict["cf2"] = self.validated_data.get("cf2", '') return user_dict However, this does not create an Account object, when a user registers. My two questions are thus: How can I create an Account object on registration? (Is this the appropriate design decision anyway?) (Possibly related to 1) How can I properly create a custom registration serializer? -

Generating a page dynamically in Django
I'm tyring to generate a page dynamically in Django but i can't find a way to do this. In my DB, i have a table containing some items, this table is "dynamic"; so i will keep adding and removing items from this table. Now, this is what i would like to do: For each of these times, there should be generated a page containing some data about those items. I created a standard view and a standard template like this: views.py def home(request): return render(request, "main/home.html") home.html {% extends "main/header.html" %} {% block content %} { Here should be data about the X item } {% endblock %} I would like to create something like this: When a page is opened, the user is redirected to a page looking like this: site.com/home/item1 or site.com/home/item2, so instead of the line { Here should be data about the X item }, there should be data about the corresponding item. Can someone give me some help? -
Looking for format for KeywordsField.save_form_data
I have a Mezzanine Project and am trying to update the keywords on a blog entry. I am having difficulty getting the format write to call KeywordsField.save_form_data this invokes a js that will update the keywords on a blog post.

Django-Filer Canonical URLS not working properly (Page not Found)
I am using Django-Filer in my admin on a Django web project which is hosted in PythonAnywhere. I have gone through the installation instructions but I am having trouble accessing the canonical urls the Filer makes for each file. It seems I am being directed to an extended url that Filer.urls is not recognizing (the non-canonical part starts at /filer-public/; this is a directory that is being created and storing my files on the separate PythonAnywhere file directory). Is there an error in my urls syntax? An error in my views.canonical? I am unsure of why plugging in the exact canonical url redirects me to this extended version of the url.

How to Reference Variable From Different View (Django)

Annotating a queryset with objects from a different "filter" queryset
If you're filtering a queryset using values from a different queryset, what is the best way to annotate the "filter" value onto the original queryset? For example, below I have a simGrants QS that I'm filtering using the simKeys QS. When a match is found, I'd like to append the matching simKeys cosine score to the simGrants object. The database is fairly large so I'm looking to find the most computationally efficient way to do this. Simkeys =similarity_matrix.objects.filter(y_axis__in=profiles).filter(cosine_score__gt=0) simGrants = Grant.objects.filter(indexKey__in=simKeys) -
Django: Creating an intermediate form with radio buttons that redirects the user
I have a Django project in which the user registers (this is the default user registration in use) and after registration I want them to be able to select an option - W or WP (radio buttons). Depending on the button they select, they would be re-directed to an appropriate profile page. (e.g profile-W or profile-WP) The "more info" intermediate page looks like this (html) more-info page showing two radio button options I would like some guidance on the best way to achieve this. Am I correct in thinking the first two steps would be to 1) Create a form for the more-info page 2) Create a view that would re-direct users to a profile. So far, I have this forms.py from django import forms from django.contrib.auth.models import User from django.contrib.auth.forms import UserCreationForm from .models import Profile """ Step 1- Create a More Info form class MoreInfoForm(): choice = forms.ChoiceField(required=True, widget=forms.RadioSelect( attrs={'class': 'Radio'}), choices=(('option1','I am a W'),('option2','I am a WP'),)) """ views.py """ STEP 2 - Create another view def moreinforequest(request): if request.method =='POST': form = UserMoreInfoForm(request.POST) #create a form that has the data that was in request.POST if form.is_valid(): #is the form valid (has something been ticked?) form.save()#this just … -

Django Admin: Save formset for TubularInline

I've tried what Django doc suggests https://docs.djangoproject.com/en/1.11/ref/contrib/admin/#django.contrib.admin.ModelAdmin.save_formset and it doesn't work. Nothing gets saved. I've tried something like In Django, how do I know the currently logged-in user? It doesn't work. Nothing gets saved. I'ev tried Django InlineModelAdmin - set inline field from request on save (set user field automatically) (save_formset vs save_model) which is essentially the same as the doc, nothing gets saved. -
