Django Accounting/ Book Keeping/ Ledger App Open Source
I am on quest for an all in one accounting/book keeping/ ledger software for Django. After slaying many a dragons, exploring deep dungeons and looking for threads on all websites, I was able to find some old applications built on, which are not compatible with latest django versions. List of some are as follows: https://github.com/dulacp/django-accounting https://github.com/prikhi/AcornAccounting https://github.com/kunkku/django-financial-accounting And so on.. Further searches in other realms made me realize there are some good open source apps for other platforms like, for PHP: https://akaunting.com/ So much of efforts don't seem to lead me to any satisfactory destination. Finally I thought, why not consult with all my mates here. Here I am on my quest, in need of help from you guys, If you have any idea about such app or you can give me any lead in solving this puzzle, it will be a great help. -

Deploying my Django-React app on Heroku with static files served through AWS S3
My SPA works fine locally (React app served by Django via runserver) but when deploying my Django-React app on Heroku and serving my static files by AWS S3 using django-storages and boto3, everything (compiled js, css, media files, etc.) works fine except that static images referenced via React does not render. Basically, everything else has a url like this:https://<my-bucket>.s3.amazonaws.com/static/js/main.js while my static image url remains like http://127.0.0.1:8000/static/media/logo when ran locally and http://<mysite>.herokuapp.com/static/media/logoon heroku.

Django Admin, Collapsable text boxes
How do I get these Textboxes to be collapsible? I went through the documentation and this is what I wrote, but the changes are not being reflected. Also, Is there any alternative I can use instead of limiting the user to select a max of 2 project manager or testers or what ever user they want to specify? (Is there a way such that, the user can click on a + button or something so that another user can be listed is what I mean) class FlatPageAdmin(admin.ModelAdmin): fieldsets = ( (None, { 'fields': ('Project_Name', 'Project_Description', 'Admin_Name', 'Admin_Mail_ID', 'Project_Manager_1', 'Project_Manager_1_Mail_ID', 'Technician_1', 'Technician_1_Mail_ID', 'Tester_1', 'Tester_1_Mail_ID', 'Status_of_the_project', 'Created', 'Finish_Date', 'Supporting_Documents', ) }), ('Add More Users', { 'classes': ('collapse',), 'fields': ('Project_Manager_2', 'Project_Manager_2_Mail_ID', 'Technician_2', 'Technician_2_Mail_ID', 'Technician_3', 'Technician_3_Mail_ID', 'Additional_User_1', 'Additional_User_1_Type', 'Additional_User_1_Mail_ID', 'Additional_User_2', 'Additional_User_2_Type', 'Additional_User_2_Mail_ID', 'Additional_User_3', 'Additional_User_3_Type', 'Additional_User_3_Mail_ID', ), }), ) -

django unable to pass request to form while using formset. Produces `__init__() got an unexpected keyword argument 'request'`
#forms.py class RequestModelForm(forms.ModelForm): def __init__(self, *args, **kwargs): self.request = kwargs.pop("request") super(RequestModelForm, self).__init__(*args, **kwargs) class BusinessForm(RequestModelForm): class Meta: model = Business fields = ('title', 'stitle', 'gstin', 'address') def clean_gstin(self): user = self.request.user gstin = self.cleaned_data['gstin'].upper() if Business.objects.filter(owner=user, gstin=gstin).exists(): raise ValidationError("A Business with that GSTIN already exists") return gstin #views.py class BaseFormView(FormView): def get_form_kwargs(self): kwargs = super(BaseFormView, self).get_form_kwargs() kwargs['request'] = self.request return kwargs def form_valid(self, form): self.object = form.save(commit=False) self.object.save() return super(BaseFormView, self).form_valid(form) class Meta: abstract = True class BusinessCreateView(BaseFormView): BusinessFormSet = formset_factory(BusinessForm, extra=3) form_class = BusinessFormSet success_url = '/dashboard' template_name = "business/business_create_form.html" Everything works well if I set extra=1 for the formset_factory. But when extra = 2 or something greater than 1, the error is thrown: __init__() got an unexpected keyword argument 'request' I have identified the problem here. Since I'm popping request inside the __init__ function of RequestModelForm(which is called multiple times when extra is set to more than 1). And there is no request since it is already been popped. I tried doing self.request = kwargs.get("request") instead of self.request = kwargs.pop("request"). But this throws another error 'BusinessForm' object has no attribute 'request'. How to overcome this? Any Help? -

Django 1.11 JavaScript catalog not translating text in JavaScript files

Django REST - Serialize User.get_all_permissions
I am building an application with a Django Rest backend, and a VueJS front end and am working through authorization and authentication. I have the authentication working well, but am a bit stuck on letting the front end (VueJS) know what the user has authorization to do in terms of Add/Change/View/Delete for a model. For example, if a user cannot add a customer, I don't want to show the 'Add Customer button'. Working through the Django docs, and solutions on StackOverflow, I believe the simplest way is to send the user's permissions from Django to VueJS. The 'best'/'simplest' way I can see to get the permissions is with the following: userModel = User.objects.get(request.user) return User.get_all_permissions(userModel) Where I am stuck is exactly where to put this logic and how to serialize it. Does the above belong in the View, Serializer, other? Up until now, I have only been working with Models (ModelSerializers and ModelViews), but I don't believe this falls into this category. Thanks in advance... -
In Django, how do you keep a module's url configurations encapsulated inside the module?
Currently, I import url configurations into my Django project with: from django.conf.urls import include from django.contrib import admin from django.urls import path, re_path from rest_framework import routers from greeter.views import GreeterViewSet ROUTER = routers.DefaultRouter() ROUTER.register(r'greeters', GreeterViewSet) urlpatterns = [ path('admin/', admin.site.urls), re_path(r'^', include(ROUTER.urls)), ] Is there a way where I can move these parts of the code: ROUTER = routers.DefaultRouter() ROUTER.register(r'greeters', GreeterViewSet) into a separate file in greeter/urls.py? And still keep these URLs: GET /greeter/ to fetch list of greeters POST /greeter/ to create a new greeter I have tried: my_project/urls.py from django.conf.urls import include from django.contrib import admin from django.urls import path, re_path urlpatterns = [ path('admin/', admin.site.urls), re_path(r'^greeters/', include('greeter.urls')), ] greeter/urls.py from django.conf.urls import url, include from rest_framework import routers from .views import GreeterViewSet ROUTER = routers.DefaultRouter() ROUTER.register(r'^', GreeterViewSet) urlpatterns = [ url(r'^', include(ROUTER.urls)), ] But got: $ curl -H 'Accept: application/vnd.api+json; indent=2' -X POST http://localhost:8000/greeters/ { "errors": [ { "detail": "Method \"POST\" not allowed.", "source": { "pointer": "/data" }, "status": "405" } ] } In case it helps, here is my original question that has been resolved: Method "POST" not allowed with Django Rest Framework -
How to represent this two level deep relationship in Django Admin?
The scenario is like this, I have three models : Category, Subcategory and Posts and reltionship among them is like this. class Category(models.Model): cat=models.CharField(max_length=10) def __str__(self): return self.cat class Subcategory(models.Model): cat=models.ForeignKey(Category,on_delete=models.CASCADE,null=True) subcat=models.CharField(max_length=10) def __str__(self): return self.cat class Posts(models.Model): title=models.CharField(max_length=15) subcat=models.ForeignKey(Subcategory,on_delete=models.CASCADE,null=True) def __str__(self): return self.title Everything is fine. I have added categories from admin panel and added and linked subcategories with categories too. I, however, want to add posts from admin panel too. Now, the problem is when I'm adding a post from admin panel and selecting subcategories, it lists all the subcategories from all the categories( which is obvious as I have subcategory field in post model). I don't want this behavior, I want to get subcategories from only certain category while saving. For eg: I have a category Django and its subcategories ORM, VIEWS. Plus I have additional subcategories from other categories, say C++. So, If I am publishing a Post and I want that to come from Django category, it should only list ORM and VIEWS in the suggestion in the admin panel. I'm open to make modification in models, like if an additional field is required or something similar like that. Any leads appreciated. -
How to rename owner to owner_id in ModelSerializer using PrimaryKeyRelatedField?
I would like to rename my owner field to owner_id since it is not nested and will only contain the owner's id. I've made some attempts, but receive errors such as {"owner":["This field is required."]}. Here is my serializers.py: class UserJobApplicantSerializer(serializers.ModelSerializer): job_id = serializers.PrimaryKeyRelatedField(source='job', queryset=Job.objects.all()) owner_id = serializers.PrimaryKeyRelatedField( source='owner', read_only=True, default=serializers.CurrentUserDefault() ) class Meta: model = JobApplicant fields = [ 'id', 'job_id', 'owner_id', 'timestamp', ] read_only_fields = ['id',] The view overrides the perform_create and injects the owner_id into the validated_data: class UserJobApplicantAPIView(generics.ListCreateAPIView): lookup_field = 'pk' serializer_class = UserJobApplicantSerializer permission_classes = (IsAuthenticated,) def get_queryset(self): return JobApplicant.objects.filter(owner=self.request.user) def perform_create(self, serializer): serializer.validated_data['owner_id'] = self.request.user.id return super(UserJobApplicantAPIView, self).perform_create(serializer) What is the correct approach to doing this? Is it possible using PrimaryKeyRelatedField, or would I need to use another type of field (or custom)? I have it working for job_id but job_id is different since it's provided by the user. I'm using DRF 3.8.2 with Django 1.11.15. -

Changes to my Angular js file will not show
I am trying to figure out why changes to my app's angular js file will not show. I am running a Django app and every time I make changes to the app I do a collectstatic and compileall. The changes would be to a grid table's row name. I have completely changed the name then ran those commands. What I see after restarting the Nginx server and uwsgi would be the old table row names. Am I missing something here? Every other change that I have made seems to be working fine. -
