Django inline formset
I have a parent and several child forms using an inline formset. It works fine. Depending on a value in the parent form, I need to check that the right number of child forms has been submitted. I know I can access the parent form using self.instance.FOO when overriding BaseInlineFormSet and again this works fine, but I can't find a way to determine how many actual forms have been submitted and vitally have data in them. Anyone know how? Many thanks -

Where is User Class using MongoDB(Djongo) in Django
I am using Django2.1 with MongoDB, Djongo ORM. as you can see the documentation of Djongo is very short and incomplete. I want to write a custom user model that inherits from the django's original User Model. since it's nosql and MongoDB, I've installed djongo and all my models inherits from djongo.models.Model, not standard django.models.Model. and unfortunately this djongo.models unlike django.models has no such a class named User. but somehow there is a auth_user collection im my mongoDB after makemigration and migrate my project and registered normally in my admin panel. I understand probably there is no such a thing "inheritance" in nosql database, if that's so, where is this user model that creates auth_user collection ind DB and holds all my user's info. I want to manipulate it directly. Regards. -
Django calling a function and coming back to same function
Currently I have around 5 functions where I use a common code. I was trying to keep this common code as a function and call in these 5 functions. This will be my common function: def commonfunc(key): do something These are kind of my other 5 functions where I use this common code. To change something I have to edit all my 5 functions. I am looking to call this common function in these 5 common functions. def func1(request) do something... commonfunc(key) use commonfunc.... return httpsresponse(request,.....) In this code everything works till second line. Thereafter it does not comeback to func1 and do rest of things. What I am missing? -
Add Json data to Django model automatically and only once
I created a method that saves Json data to a Django model: models.py: class Object(models.Model): name = models.CharField(max_length=100) address = models.CharField(max_length=100) @classmethod def save_json_data_to_model(cls): with open('data.json', encoding='utf8') as file: data = json.load(file) for obj in data: Object( name=obj['name'], address=obj['Street']).save() When i was testing the project I ran the method in the shell and everything is working fine. But I want the data to be populated in the model automatically and only one time. What is the best way to achieve this? I tried this in views.py: if __name__ == '__main__': Obj.save_json_data_to_model() -

How would one change this function based view into a class based view?

How to generate Bootstrap DatePicker datesDisabled dynimcally
Working with Django and Ajax. I have used Ajax to get my dynamic dates, now the issue is feeding the dates to the datesDisabled: [] array. When i alert(data) i get my dates alerted perfectly.

Timezone randomly changes in Django admin
There are two instances of a Django project deployed using uWSGI server with NGINX proxy on Ubuntu server 14.04. In settings I have: TIME_ZONE = 'Europe/Moscow' # UTC +03.00 USE_TZ = True On one instance Dates and Times are displayed in correct time zone. On another instance time zone keeps changing between +03.00 and +12.00 and I didn't manage to notice any pattern in that. I checked: Ubuntu time zone with timedatectl status (the same on both servers) PostgreSQL timezone (the same on both servers) uWSGI and NGINX setting are kept in VCS, so they are the same as well (although doesn't seem to have anything time zone related) The only difference I can think of is that the properly working instance is on Azure, while the problematic one is physically hosted in UTC +03.00 (local cloud provider). However, other Django projects hosted there work properly. What else can I check to isolate and solve this problem? -
dj-stripe UpcomingInvoice usage
Towards the end of a free trial period I am trying to send customers a notification that they will soon be charged with dj-stripe. I am trying to use a webhook to initiate the notification and then UpcomingInvoice to retrieve the amount. I can see in my stripe dashboard that I have customers with trial ending tomorrow and an upcoming invoice, however dj-stripe always returns an empty queryset. In PDB when I try the code I also can't see any calls to the stripe api which would need to occur to pull the data. @webhooks.handler("customer.subscription.trial_will_end") def charge_upcoming(event, **kwargs): UpcomingInvoice(customer=event.customer).invoiceitems pdb.set_trace() <QuerySetMock []> What am I doing wrong? Thanks! -

Serving static content with Django, Gunicorn and Ngnix in shared development environment
I have seen many great answers to this question here on SO, but either I don't understand them or they don't apply to my particular circumstance. I have looked here: Serving static files with Nginx + Gunicorn + Django and many others. I have followed the recommendation in those answers and I still do not have solution that works. I hope that if I explain exactly what I am doing then maybe someone will tell me where I went wrong. I developing in a shared environment with several other teams and we share an ngnix server.

Django Rest Framework update() with kwargs from validated_data
Can I update instance in one line without specifying all instance fields? For example: def update(self, instance, validated_data): instance.name = validated_data.get('name', instance.name) instance.address = validated_data.get('address', instance.address) instance.save() return instance So imagine if there's many more fields next to name and address. Can I do something extracting kwargs from validated_data? Just like in create() method: def create(self, validated_data): return Person.objects.create(**validated_data) -

Adding fields for User in admin page in django
This problem seems to be very simple, yet i can't find solution. I needed to extend my User model (add phone number) in django, and i picked the way of creating another model called UserInfo that is related 1to1 with User model. It works fine, the only problem is that I can't get the UserInfo fields (the phone number) to show up on User page in admin panel. What i tried: from app.models import UserInfo from django.contrib import admin from django.contrib.auth.models import User class UserInfoInline(admin.TabularInline): model = UserInfo class UserAdmin(admin.ModelAdmin): inlines = [UserInfoInline,] admin.site.register(UserInfo) -

Trying to pass django-oscar products to custom template
I'm working on a custom template using a forked version of django-oscar apps (to have custom models). I am trying to display a list of all the products in the product table, just to start with. I looked at django-oscar templates but as they rely on a lot of custom tempaltetags I found it too complex to rewrite everything to work with my models. This is what I have in my views.py: def product(request): template = loader.get_template('/home/mysite/django_sites/my_site/main_page/templates/main_page/product.html') prodlist = Product.objects.all() return HttpResponse(template.render({}, request), context={'prodlist': prodlist}) And the code I am using in my template to try and display it {% for instance in prodlist%} <li>{{ instance.name }}</li> {% endfor %} However, this gives me an error TypeError at /product/ __init__() got an unexpected keyword argument 'context' /product corresponds to my product view in my urls.py This was my best guess from following tutorials and looking at other answers. What am I getting wrong? -
Django DB data delete and backup
I have one django project. Some data is restored in the Model database. But in the web, there is some function to delete such data for the new demonstration in the page. However, I don't want to complete delete such data for possible further usage like statistics. How could deal with such issues normally? I can think about transferring such data to another Model database before deleting, but is it too complicated? Or any other suggestion? Thx! -
