How to create object within nested serializer on API create call
I have an API with nested serializers where I overwrote the create method. My nested serializer has Foreign Keys to another model. Now I want to create objects of this other model in the same API call. This is where I am stuck. My data looks like so: [ { "project": "project1", "name": "Graph1", "description": "testdescription", "nodes": [ { "id": 16, "name": "target1", "graph": 49 }, { "id": 15, "name": "Node1", "graph": 49 } ], "edges": [ { "id": 14, "name": "Edge1", "graph": 49, "source": 15, "target": 16 } ] } ] The fields source and target are Foreign Keys to the model Node. Now, I can send this data without a problem when the fields source and target are already existent in the database. But what I want is, that I send the data and I create a new Node object (source) and a new Node object (target) in the same call. So far I overwrote the create method to enable nested serialization like so: class GraphSerializer(serializers.ModelSerializer): nodes = NodeSerializer(many=True) edges = EdgeSerializer(many=True) class Meta: model = Graph fields = ('project', 'name', 'description', 'nodes', 'edges', ) def create(self, validated_data): nodes_data = validated_data.pop('nodes') edges_data = validated_data.pop('edges') graph = Graph.objects.create(**validated_data) for … -

Django - How To Use Form In Footer
Previously, I had my 'subscribe to newsletter' form on the home page (index.html). However, I moved it to the footer.html in order for it to be shown on every page. The issue is that since the logic to deal with the form is only in the home view, submitting to the form only works on the home page. Here is some code to help you understand: This is in footer.html which is included in base.html which is extended by all other htmls <form class="nwsltr-primary-1" action="." method="POST"> <!-- . means current URL we are on --> {% csrf_token %} <input type="email" name="email" id="email" placeholder="Your email"/> <button type="submit"><i class="ion-ios-paperplane"></i></button> </form> This is what I think needs to change. This is the view for the home page and the only place the logic for the form is being seen: def index(request): # featured and object_list get all Posts with featured bool true. order_by=latest first. :6=first 6 featured = Post.objects.filter(featured=True).order_by('-share_count')[:6] latest = Post.objects.order_by('-timestamp')[:5] popular = Post.objects.order_by("-share_count")[:4] # Basic but does not do any verification if request.method == "POST": email = request.POST["email"] new_signup = Signup() new_signup.email = email new_signup.save() context = { 'object_list': featured, 'latest': latest, 'popular': popular } return render(request, 'index.html', context) # html … -
Circular dependency created by serializer
When importing a serializer into my model the model cannot be imported anymore so I suspect there is a circular dependency. When not importing the serializer everything goes smoothly but when importing it everything breaks. This works from shift.models import Shift class ShiftChangeRequest(models.Model): shift = models.ForeignKey(Shift, on_delete=models.CASCADE, null=True) And this does not: from shift.models import Shift from shift.serializers.base import BaseSerializer class ShiftChangeRequest(models.Model): shift = models.ForeignKey(Shift, on_delete=models.CASCADE, null=True) As you can see the ShiftChangeRequest does have a connection with shift but in the BaseSerializer ShiftChangeRequest is not even mentioned: from rest_framework import serializers from shift import models class BaseSerializer(serializers.ModelSerializer): class Meta: model = models.Shift fields = [ "id", "title", "start", "end", "amount_of_minutes", "amount_of_employees", "client", "skills", "users", "repeat_at", ] I expected that everything worked as before the import but I get the error ImportError: cannot import name 'ShiftChangeRequest' -

Use autocomplete_fields with Proxy model
I want to implement autocomplete_fields feature but it doesn't work. I assume it happens because of Proxy model. So I have Customer Proxy model and PromoCode model. PromoCode has FK to Customer model. And I need to have search field for customers in PromoCode change form. Here are models and admin classes: class User(AbstractUser): # bunch of fields class Customer(User): class Meta: proxy = True class CustomerAdmin(admin.ModelAdmin): search_fields = ['email',] admin.site.register(Customer, CustomerAdmin) class PromoCode(TimeStampedModel): customer = models.ForeignKey(User, on_delete=PROTECT, null=True, blank=True) class PromoCodeAdmin(admin.ModelAdmin): autocomplete_fields = ('customer',) admin.site.register(PromoCode, PromoCodeAdmin) This code gives error: : (admin.E039) An admin for model "User" has to be registered to be referenced by PromoCodeAdmin.autocomplete_fields. But I can't change model in customer field to Customer, becase when I run migration it breaks with following error: ValueError: The field coupons.PromoCode.customer was declared with a lazy reference to 'users.customer', but app 'users' doesn't provide model 'customer' Also I can't register User as admin class, because I don't need it to be registered. I register Customer model. What can I do to solve such case? -

multilingual site: how create clean relationship between "static" texts (coded into templates) and database?
On a multilingual (manually translated) website appropriate translations of products or newspaper-articles are pulled out according to user (or user-selected) language. But what about all those annoying "static" texts that ordinarily get coded directly into a template? Perhaps "opening hours" or "contact us"? Obviously these need to exist in various translations (and therefore in the database), my question is how to develop clearly the relationship between database entry and code? So far was thinking of the following: MODELS Language name Article article_title article_slug Translation article =models.ForeignKey(Article) language =models.ForeignKey(Language) title_text article_text VIEWS def page12view(request) article = article.objects.get(slug=friendly-name-of-article) query = Translation.objects.filter(article=article).filter(language=request.user.language) if not query.first(): #if translation not available in user’s language default to ENGLISH (pk=1) query = Translation.objects.filter(article=article).filter(language=1) context = { ‘friendly-name-of-article’: query.first()} return render (request,’page12.html', context) TEMPLATE {{friendly-name-of-article.title_text}} {{friendly-name-of-article.article_text}} The idea revolves around giving each article a slug (referred to in above example as "friendly-name-of-article"). Thus "about-us", "opening-hours"etc.. That string would be copy-pasted in the view and template as suggested in the code. The idea is that it would at least bring some clarity as to what is going on. But is it a good idea? Have my doubts... Any good practices to share? -

Django Inlineformsets - Custom validation with django-extra-views
So I have a question about the form_valid for django-extra-views. I used the CreateWithInlinesView method to create a form with multiple inline formsets.

An Order always has to include a minimum of one Booking but does not necessarily need to have a Payment when the Order is created. The form for the Payment will be generated nonetheless. I would like to validate the Payment form on a "payment_amount" > 0.
