How to change React frontend and Django backend to load as one Heroku application
I've built a React frontend in the style of this tutorial: https://codeburst.io/react-image-upload-with-kittens-cc96430eaece (source code here) This is connected to a Django backend (already had experience with Django, so don't have an example tutorial there). Running the frontend and backend locally works fine. Now I want to deploy it as one application to Heroku, so I followed this tutorial about how to do this: https://www.youtube.com/watch?v=r0ECufCyyyw (source code here) I configured the Django application exactly like in the video tutorial. The application builds successfully but the page is empty. I think it might be because I didn't use routers in the React application, but I don't know what exactly it's supposed to do so that the code in App.js gets called. Any suggestions greatly appreciated - I'm not sure where to start and I've found so many ways to write a React app I'm having trouble separating important differences from the inessential. -
how to get column names from a Django object list
I'm trying to generate some tables based on Django models to make them modifiable and alter the database, and since i have more than 200 tables i'm trying to generate them automatically instead of hardcoding each one. in this example i'm trying to get the table columns in django template so i can generate the table with for loops only. here is my views.py class bclist(ListView): template_name = "table2.html" queryset = BaseCase.objects.all() and here is my template <table border="1px"> <tr> <th>Base Case Name</th> <th>version</th> <th>default</th> </tr> {% for instance in object_list %} <tr> <td>{{ instance.base_case_name }}</td> <td>{{ instance.version }}</td> <td>{{ instance.default }}</td> <td><a href='/{{ instance.pk }}/update' >edit</a></td> <td><a href='/{{ instance.pk }}/delete' >delete</a></td> </tr>{% endfor %} </table> my models.py class BaseCase(models.Model): base_case_name = models.CharField(primary_key=True, max_length=255) version = models.TextField(blank=True, null=True) default = models.IntegerField(blank=True, null=True) -

Django models: where should consistency/integrity of databases stay?
Here again, I’m trying to understand Django philosophy for databases. When dealing about consistency in databases, I understand (or understood?) that it refers to constraints, cascades, triggers, etc. at database level, hence a solid database diagram is (or was) very important. But I don’t feel that with Django, it seems that its philosophy is to bring all that consistency to every app in a Django project, and to leave database with relations only. Because when migrating from models to database, not all rules defined in models are taken to database, example: validators. For a moment, let's accept that all business rules are defined in models only. I could (hardly) accept that if it was not because while I was using the database API, no rule (defined in models) applied on every record saved into database, then danger alarms sounded. Here the dilemma: If consistency and/or business rules were defined at database level, why would I need define rules in models again? is it not redundant? If consistency and/or business rules were defined in models, is the database not exposed to concurrency and data integrity problems? In PHP, you interact with database through connectors, consistency/integrity of database is managed by itself. … -
Runtime error when trying to run a Django app
I'm trying to run a django project I worked on a while ago. Most of what I did I've forgotten. I get a run time error when launching the project. I only just imported these files over to my computer.

Using models at a project level
I know that this question has been posted a few times in different variations but I'm not satisfied with the answers I found so I will explain you my problem, which I think will be easily solved by someone used to Django. So, I'm a beginner with Django and my problem is that I'm building a food delivery website and I have lots of models such as User, Meal, Order, ... that will be used in all the applications of my project. But, from my very little experience with Django, I understand that the models are defined at an app level, not at a project level. How can I deal with that ? I tried defining some models in an app and importing them in the other apps but I doesn't work : for example, I defined my Client model in the registering app, and my Order model in the ordering app. But when I write "from registering.models import Client" in the Order.models file in order to have a foreign key between Order and Client I have an error saying that it can't find a model Client in the ordering app. I believe there is some way to define the … -

Datetimepicker in django changing date format from DD/MM/YYYY to MM/DD/YYYY when the forms comes pre-filled
when i want to update a Date in any form, the datepicker is changing from DD/MM/YYYY format to MM/DD/YYYY.

List names of required fields in Django Rest Framework serializer (and ignore parent fields)
What I'm trying to do is get a list of all the fields in a serializer which: Do not contain required=False as a parameter. Do not come from the parent serializer. For example, if I have serializers like: class ParentSerializer(serializers.Serializer): parent_field = serializers.IntegerField class ChildSerializer(ParentSerializer): child_field_required = serializers.IntegerField child_field_not_required = serializers.IntegerField(required=False) I'd like the resulting output to be: ['child_field_required'] I've figured out I can get an ordered list of the declared fields like: self.get_serializer().get_fields() >> OrderedDict([ ('parent_field', IntegerField()), ('child_field_required', IntegerField()), ('child_field_not_required', IntegerField(required=False)), ]) But I haven't been able to move past this step. -

REMOTE_USER is empty in the django after redirecting
It seems to me that I do not quite understand the REMOTE_USER variable. I have three instances based on different hosts: nginx, django_auth_server, django_app_server. I am trying to implement "single sign on": the user logs on to the django_auth_server via nginx, is redirected to the django_app_server and continues surfing without authentication.

Formset using class-based views with multiple instance
I want to use formset to add multiple todo at once, I have been told to use formset, which is exaclty what I am looking for, but all the documentations and video tutorials are using function based view.

language independent query with django-modeltranslation
I currently started to use django-modeltranslation in a Django app and I would like to make a query to retrieve the instance of a model, independent of the language set in the system. For example I have the following model: class Product(models.Model): description = models.CharField(max_length=200) sku = models.CharField(unique=True, null=False, max_length=30) price = models.DecimalField(max_digits=8, decimal_places=2) and the following in translation.py: class ProductTranslationOptions(TranslationOptions): fields = ('description', 'sku') translator.register(Product, ProductTranslationOptions) and the Django setting: gettext = lambda s: s LANGUAGES = ( ('en', gettext('English')), ('de', gettext('German')), ) MODELTRANSLATION_LANGUAGES = ('en', 'de') MODELTRANSLATION_DEFAULT_LANGUAGE = 'en' MODELTRANSLATION_FALLBACK_LANGUAGES = ('en',) Let's create a product instance: Product.objects.create(description_en='product en', description_de='product de', sku_en='sku-001', sku_de='sku-002', price=10.0) Now I want to find the instance with the sku sku-002, to retrieve the price of a product (which is independent of the language). Product.objects.filter(sku='sku-002') However this returns an empty MultilingualQuerySet. Only the following returns the correct Product instance. Product.objects.filter(sku_de='sku-002') or from django.utils import translation translation.activate('de') Product.objects.filter(sku='sku-002') I guess this is the intended behavior of django-modeltranslation, but sometimes it would be practical to find an instance independent of the language. A solution could be to iterate through all LANGUAGES and try to find the instance for each language: from django.conf import settings LANGUAGES = … -
Handle .envs in docker and gitlab ci without having it in the repository
I am running a dockerized django app that uses Gitlab CI for automated tests. In my .env/ folder I have a .local and a .production file that contains my environment variables that are read in my setup-file with env = environ.Env() env(...). I think that is pretty standard. Up until now my .env/local file was committed in my repository and the tests need it to run because in my docker compose file I have: env_file: - ./.envs/.local/.django - ./.envs/.local/.postgres and I run my tests in gitlab CI using docker-compose -f local.yml run django pytest. Now I do not want my local env file in my repository. Simply because it is bad practice and I would also like to store some secret keys like AWS etc in there. But then it breaks my tests. Is there any recommended way on how to achieve what I want? Or is that not possible? I tried to add another .secret file, but also this one I have to specify in my compose file.

Django how to annotate manytomany field with count
Considger the following: class ModelA(models.Model): pass class ModelB(models.Model): model_as = models.ManyToManyField(ModelA, db_index=True, related_name="model_bs", blank=True) model_bs = model_a_object.model_bs.all() for model_b in model_bs: print(model_b.model_as.count()) 3 2 So far so good. But I want to created an ordered list of model_bs depending on the count of model_as.
