Django rest framework: load model data into serializer maually (to then send it as an HTTP payload / webhook)
So we have a post-save signal that calls a celery task that is using requests to notify one of our partners about an order by a user he has referred to us. I would like the payload to equal the detail view output of the order. So far so good. However, for test-ability purposes and also to avoid unnecessary HTTP calls, I would like to retrieve the instance from the DB (in the celery task), feed it to the serializer (OrderDetailSerializer) and then call requesst.post with serializer.data What is the easiest way to achieve that The closest question to this one I found is this Using Django rest framework as a rest client The answer suggested to use simple JSON serialization. However, it is not a good solution for us because the serializer hides some sensitive data and ads some nested data via NestedSerializers. -
python django logging: One single logger with more than one logging level
tl;dr: Is there any way to have one single logger that manages all loglevels? I am using the logging library on a certain django project. Django manages logging exactly the same as the regular logging library, but with the benefit that you can declare loggers, handlers, filters, etc. on a separate settings.py file. Currently, I have some loggers and handlers on my settings.py: LOGGING = { 'version': 1, 'disable_existing_loggers' : False, 'loggers': { 'info': { 'handlers' : ['std_err', 'info_logfile'], 'level': 'INFO', }, 'info.contract': { 'handlers': ['contract_info_logfile'], 'level': 'INFO', 'propagate': True, } }, 'handlers': { 'std_err': { 'class': 'logging.StreamHandler' }, 'info_logfile': { 'class': 'logging.FileHandler', 'filename': 'info.log', 'formatter': 'default', }, 'contract_info_logfile': { 'class': 'logging.FileHandler', 'filename': 'contract.info.log', 'formatter': 'default', } } 'formatters': { 'default': { 'format': '%(asctime)s [%(module)s] %(message)s', } } } In my code, I simply run: logger = logging.getLogger('info.contract') logger.info("Some info message...") Which prints 2021-01-24 03:05:02,063 [contract_generator] Some info message... to console. This works very well and is what I expect. The problem I am having is the following: In order to log to different files depending on the loglevel, I would have to create a new logger for each loglevel. Which is to say, the following doesn't work: logger = … -
Using Django, SimpleJWT checking User permission to show content belongs to his own company
I am using React(front), Django(server-side), Simple JWT for User Auth Model and Postgres DB. Let me explain my model: Company owns many properties, and each company has multiple users. As a user logs in, I want them to see a list of properties that belongs to their own company. As the user selects any property from the list, I need to again check if the user has permission and then run the queries. I am currently using Simple JWT for authentication. As the user logs in, the backend generates Access and Refresh tokens. With every request sent from the user side, I am sending JWT access token. On the server side, I want to decode the token, look at what company user belongs to, filter queries accordingly and send the JsonResponse. Here is my Company Model: class Company(models.Model): owner = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='company_user', on_delete=models.CASCADE, null=True) company_name = models.CharField(max_length=200, null=True) slug = models.SlugField(max_length=200, unique=True) class Meta: ordering = ['name'] def __str__(self): return self.name Here is the property model: class Property(models.Model): company = models.ForeignKey(Company, related_name='prop_company', null = True, on_delete=models.CASCADE) property_name = models.CharField(max_length=200, null=True) property_type = models.CharField(max_length=200, null=True) def __str__(self): return self.property_name Here is the property data class PropertyData(models.Model): data = models.ForeignKey(Property, related_name='property_data', null … -
Updating database on Django
Good day SO. I want to ask something basic. I tried on my end to update my data from html to save to database but to no avail. My Model structure is Account extends to AbstractBaseUser, BaseUserManager and CompanyAccount links to Account by OneToOneField. I can say that my Model should have no problem since I can Register Account and Company Account without any problems. views.py @login_required(login_url='/login/') def user_my_page(request, *args, **kwargs): context = {} context['form_type'] = 'update' context['account_type'] = request.user.account_type if request.POST: if request.user.account_type == 1: company = CompanyAccount.objects.get(account=request.user) account_form = CompanyAccountForm(request.POST, instance=request.user) if account_form.is_valid(): account_form.save() print(request.POST) print('SAVE') else: print('ERROR') forms.py class AccountCreationForm(UserCreationForm): accuser_id = forms.CharField(max_length=10, help_text="Required") class Meta: model = Account fields = ("accuser_id", "password1", "password2") class CompanyAccountForm(forms.ModelForm): class Meta: model = CompanyAccount fields = "__all__" def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['company_name'].widget.attrs.update({'class': 'content-input'}) self.fields['company_name_kana'].widget.attrs.update({'class': 'content-input'}) print(request.POST) <QueryDict: {'csrfmiddlewaretoken': ['6zrwt68PNiJKrgZcKanDcVJkqAtogbQbNk2wHwjOzg7ybfq3Lyei9ZqdbmAJcYrV'], 'company_name': ['TESTING'], ....etc This part here, it does print SAVE on my terminal but it does not save to the database. -

How do I add what I have written in my forms.py into views.py
Hi I have written a function in my forms.py to check to make sure that if a the form submitted has a slug or title that is the same as a blog post created before, they will return a message saying that the title already exists. How do I include this in my views.py so that it will work in the template? or did I write my function in forms.py wrongly? because the form isnt valid now. Note: There is no slug field in my form.

How to send url as slug field into url in Django
I have my urls.py as this: from django.urls import path from . import views urlpatterns = [ path('link',views.get_text,name='text'), path('link/<link>',views.show,name='show') ] When I enter a url like http://127.0.0.1:8000/link/https://www.geeksforgeeks.org/gate-cs-notes-gq/, it is showing page not found as it is checking the / in the slug url.

How to populate auth.groups and auth.group_permissions tables with initial data in Django project

Runtime model generation in Django or other languages
I'm asking this question for hearing about advice and having an idea about the possibility of this type work. Not asking for any code help, just advice, and a little leading would be helpful, if it is still the wrong place to ask this question, sorry about that. I would like to build an application that lets users upload a CSV or excel file and generate a SQL table at the backend at that time and store data into the table. Then print the loaded data in UI. I did it before in a terrible and messy way by using the Create Table query and select query for printing data. I believe you will think of me how a programmer can be so ridiculous if you see these codes. That's the reason I want to learn if there is a better and standard way to do the same thing or shouldn't do something like that at all? And how other companies do this type of works? You can advise different programming languages if there are any. I read about documents Dynamic Models. I understand a little, but they don't advise to build in that way, so I don't know if … -

How overwrite django-friendship
I am using a third party application called "django-friendship" and I want to adapt it to my project. To adapt it to my project I need to overwrite several functions and urls that come by default, but I don't know how to overwrite them. The source code is here: https://github.com/revsys/django-friendship For example, I want to overwrite the following function in views.py: def all_users(request, template_name="friendship/user_actions.html"): users = user_model.objects.all() return render( request, template_name, {get_friendship_context_object_list_name(): users} ) and for example I want this function to do nothing, just print a text on the screen (not its purpose but to make the example simpler) in this way: def all_users(request, template_name="friendship/user_actions.html"): print("Hello World") I have used the following import: from friendship.views import all_users But it does not work, it still uses the function of the third party application and not mine. On the other hand, "django-friendship" uses the following urls: friendship/ ^users/$ [name='friendship_view_users'] friendship/ ^friends/(?P[\w-]+)/$ [name='friendship_view_friends'] friendship/ ^friend/add/(?P<to_username>[\w-]+)/$ [name='friendship_add_friend'] friendship/ ^friend/accept/(?P<friendship_request_id>\d+)/$ [name='friendship_accept'] friendship/ ^friend/reject/(?P<friendship_request_id>\d+)/$ [name='friendship_reject'] friendship/ ^friend/cancel/(?P<friendship_request_id>\d+)/$ [name='friendship_cancel'] friendship/ ^friend/requests/$ [name='friendship_request_list'] friendship/ ^friend/requests/rejected/$ [name='friendship_requests_rejected'] friendship/ ^friend/request/(?P<friendship_request_id>\d+)/$ [name='friendship_requests_detail'] friendship/ ^followers/(?P[\w-]+)/$ [name='friendship_followers'] friendship/ ^following/(?P[\w-]+)/$ [name='friendship_following'] friendship/ ^follower/add/(?P<followee_username>[\w-]+)/$ [name='follower_add'] friendship/ ^follower/remove/(?P<followee_username>[\w-]+)/$ [name='follower_remove'] friendship/ ^blockers/(?P[\w-]+)/$ [name='friendship_blockers'] friendship/ ^blocking/(?P[\w-]+)/$ [name='friendship_blocking'] friendship/ ^block/add/(?P<blocked_username>[\w-]+)/$ [name='block_add'] friendship/ ^block/remove/(?P<blocked_username>[\w-]+)/$ [name='block_remove'] How can I modify … -
Is including the user field in two related models a bad practice? (Django)
I’m fairly new to Django and programming in general. I’m building a tool for a friend in the construction industry. Basically the client bids for a tender and if they win they sign a contract. A contract can have multiple projects and a project can have multiple jobs. But the user should also be able to create a job for smaller projects that are not under a contract. Every job must be under a project. If the user has a contract I want the user journey to be as the following: Create a contract -> create a project -> create a job. I want to link the contract to the user and the job to the user as well but I’m not sure if it’s a good practice to include the user field twice in two related models. I’d like to know if my solution is wrong and a bad practice, and if there’s a better solution. Thanks! class Contract(TimeStampedModel): owner = models.ForeignKey( get_user_model(), on_delete=models.CASCADE, ) title = models.CharField( max_length=100, blank=False, unique=False) starting_date = models.DateTimeField(default=timezone.now, blank=True) class Meta: verbose_name_plural = "Contracts" def __str__(self): return self.title class Project(TimeStampedModel): name = models.CharField( max_length=50, blank=False, unique=False) contract = models.ForeignKey( Contract, on_delete=models.RESTRICT, blank=False, related_name='contract', … -

In my project, a contractor can have multiple trades or skills, this should be entered in the trade field. class SubTrade(models.Model): strade = models.CharField("Trade", max_length=255) def __str__(self): return self.strade def get_absolute_url(self): return reverse ("trade_full", kwargs={"pk": self.id}) class SubContractor(models.Model): nameF = models.CharField("First Name", max_length=255, blank = True, null = True) nameL = models.CharField("Last Name", max_length=255, blank = True, null = True) nameN = models.CharField("Nickname", max_length=255, blank = True, null = True) trade = models.ManyToManyField('SubTrade') phone = models.CharField("Phone", max_length=255, blank = True, null = True) email = models.EmailField("Email", max_length=254, blank = True, null = True) address = models.CharField("Address", max_length=255, blank = True, null = True) dateC = models.DateTimeField("Date Created", auto_now_add=True) dateU = models.DateTimeField("Last Updated", auto_now=True) note = models.TextField("Notes", blank = True, null = True) def __str__(self): return '%s %s' % (self.nameF, self.nameL) def get_absolute_url(self): return reverse ("contractor_full", kwargs={"pk": self.id}) These are my views. class SubContractorCreateView(CreateView): model = SubContractor template_name = "project/contractoradd.html" fields = ['nameF', 'nameL', 'nameN', 'trade', 'address', 'phone', 'email', 'note'] def form_valid(self, form): return super().form_valid(form) This is my HTML Code {% for contractor in contractor %} Last Name: {{contractor.nameL}} <br> … -
How to get an evironment variable value in YAML file?
I am working on a Django project, and I am using GitHub for source control purposes. I am using GitHub actions to run python3 manage.py test when pushing. I don't want to post my secret key to the repository. So I stored it on an environment variable and used os.environ.get('SECRET_KEY') to keep it secret. The problem is that by doing this, GitHub doesn't know what the SECRET_KEY is. There is a way to set custom environment variables in the YAML file in the workflow directory, but if I put the SECRET_KEY there, there is no point in covering it in settings.py. Does anybody know what I can do? -
