How can I use Celery and get start time from user?
I need to make a celery task where a user has to enter time when he wants to start the process and after that at this exact time the task should be repeating every 24 hours. For example, I entered time 00:00 and when it is 00:00 the program will start running. And after that it will repeat every 24 hours. I have a code for celery where it already makes it run every 24 hours, I just don't know how to add the exact time when code needs to run. (Sorry for bad English, English is not my native) -

Django - Query_set returns an empty arraylist when it is ran in the test
I am trying to run a TestCase on my model. I already have a MySQL database (specifically MariaDB through a HeidiSQL GUI) created and connected with the respective data inside for this project.

How do I get translated word in template in django-parler?
On my frontend detail page, in templates I want to get translated words. Since translated fields is located inside translations block class UsefulLinks(TranslatableModel, BaseModel): translations = TranslatedFields( name=models.CharField(verbose_name=_('Useful Link Name'), max_length=255) ) icon = models.ImageField(verbose_name=_('Link Icon'), upload_to='') I don't know how to get translated words in template. <input value="{{ object.name.en }}" name="title_uz" type="text" class="form-control" id="exampleInputEmail1"> I tried to get like with above method, but this doesn't seem to work. Are there any ways to get translated words directly in template just by specifity language code?

Run a django app inside a docker container
I am running succesfully a django app that is hosted inside a docker container. I change something on my code on purpose in order for my code to break. What I need is somehow to see the log of the running code as if I was running this locally on my computer. For example I forgot to import a library and when I run this locally I get a message on the terminal like "ModuleNotFoundError: No module named 'somemodule'". But when i run the same code from inside the container I get no log, just the container fails to start. My question is: How can I get a log for my script from inside the container, so I can debug my code? -

How to perform Django email threading?
Can someone please share how I can do threading to send an email on a shared hosting service for my Django app?

Currently using Namecheap shared hosting. -

Make Django ORM automatically fetch properties
Say I have a Post model like this: class Post(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) text_content = models.CharField() @property def comment_count(self): return self.comments.count() Say I need to get all the data for the post with ID 3. I know that I can retrieve the user along with the post in one query, by doing Post.objects.select_related('user').get(pk=3), allowing me to save a query. However, is there a way to automatically fetch comment_count as well? I know I could use Post.objects.annotate(comment_count=Count('comments')) (which will require me to remove the property or change the name of the annotation, as there would be an AttributeError), however is it possible to make the ORM do that part automatically, since the property is declared in the model? Although I could just add the .annotate, this can get very tedious when there are multiple properties and foreign keys that need to be fetched on multiple places. -
Django URL pattern to manage creation and update in the same view - NoReverseMatch error
I'm facing a 'NeReverseMatch' error that I'm not able to solve, even if I'm quite convinced it's probably a stupid error, something I missed... as I reproduce a pattern I implemented earlier in the same app. The context is the following: I have the same view for creating and updating an object. The difference is that in the second case, I have the id. Thus, related urls look like this (I put the whole file to ensure there is no mismatch with other urls): app_name = "polls" urlpatterns = [ path("", views.index, name="index"), path("get_chart_data/", views.get_chart_data, name="chart_data"), path("set_proxy/", views.set_proxy, name="set_proxy"), path("accept_proxy/", views.accept_proxy, name="accept_proxy"), path("cancel_proxy/", views.cancel_proxy, name="cancel_proxy"), path("sign_up/", views.new_user, name="sign_up"), path("login/", views.login_user, name="login"), path("logout/", views.logout_user, name="logout"), path("<slug:comp_slug>/", views.company_home, name="company_home"), path("<slug:comp_slug>/admin_users/", views.adm_users, name="adm_users"), path("<slug:comp_slug>/admin_load_users/", views.adm_load_users, name="adm_load_users"), path("<slug:comp_slug>/admin_profile/", views.adm_user_profile, name="adm_create_user"), path("<slug:comp_slug>/admin_profile/<int:usr_id>", views.adm_user_profile, name="adm_user_profile"), path("<slug:comp_slug>/change_password/", views.change_password, name="change_password"), path("<slug:comp_slug>/admin_delete_user/<int:usr_id>", views.adm_delete_user, name="adm_delete_user"), path("<slug:comp_slug>/admin_events/", views.adm_events, name="adm_events"), path("<slug:comp_slug>/admin_create_event/", views.adm_event_detail, name="adm_create_event"), path("<slug:comp_slug>/admin_update_event/<int:evt_id>/", views.adm_event_detail, name="adm_event_detail"), path("<slug:comp_slug>/admin_delete_event/<int:evt_id>", views.adm_delete_event, name="adm_delete_event"), path("<slug:comp_slug>/admin_groups/", views.adm_groups, name="adm_groups"), # ===== THE 2 FOLLOWING LINES ARE THE ISSUE ===== path("<slug:comp_slug>/admin_group_detail/", views.adm_group_detail, name="adm_create_group"), path("<slug:comp_slug>/admin_group_detail/<int:grp_id>/", views.adm_group_detail, name="adm_group_detail"), path("<slug:comp_slug>/admin_delete_group/<int:grp_id>", views.adm_delete_group, name="adm_delete_group"), path("<slug:comp_slug>/admin_options/", views.adm_options, name="adm_options"), path("<slug:comp_slug>/<slug:event_slug>/", views.event, name="event"), path("<slug:comp_slug>/<slug:event_slug>/<int:question_no>", views.question, name="question"), path("<slug:comp_slug>/<slug:event_slug>/<int:question_no>/vote", views.vote, name="vote"), path("<slug:comp_slug>/<slug:event_slug>/results", views.results, name="results"), ] The pattern is the same for users management (adm_user_profile view) with no issue.

Override a model's DELETE method from real delete to setting a property in Django RESTful framework
We are using a django-rest-framework as our backend. I have a model Product which is the Foreign Key of another Order model, which acts as both a order and an audit log. Now suppose we are not going to sell this Product anymore. We need to apply DELETE method on the Product; and we still want to preserve everything in Order. However, if the Product is really deleted and the on_delete method on it is SET_NULL, then all info that is related to Product is lost. Which is not what I wanted. class Order(models.Model): product = models.ForeignKey(Product, blank=True, null=True, on_delete=models.SET_NULL) So my question is: A common practice in other framework is using soft-delete, i.e. adding a "delete=0" property on Product. And the DELETE method only change the property to "delete=1" rather than real delete. Is it do-able when using django-rest-framework? And how? Is there any other good practices to realize this requirement, i.e. to delete the foreign key while perserving the foreign key's metadata? -
Django Form retrieve data from database
I have a form in Django that enables me to post data to the database. I'd like to create a dropdown button that shows me the previous entries from the database, which I can select re-render the data in the original form, allowing me to update and post back to the database. I'm just starting out with Python, which I think is amazing, but I've not really grasped it yet. So I'm probably doing it completely wrong but here goes. I'm starting with just populating the dropdown. So within my models.py, I have. class Investor(models.Model): investor_name = models.CharField(max_length=255, blank=False) investor_website = models.URLField(max_length=255, blank=False) investor_portfolio = models.URLField(max_length=255, blank=False) investor_comment = models.TextField() def __str__(self): return str(self.investor_name) class showInvestor(models.Model): investorName=models.CharField(max_length=100) class Meta: db_table="apps_investor" Then within my views.py def showInvestor(request): results=showInvestor.objects.all() return render(request,"add_investor.html",{"showInvestor":results}) And then within my HTML template, i have: <div class="col-lg-2"> <div class="dropdown"> <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-bs-toggle="dropdown" aria-expanded="false">Update Existing Investor <i class="mdi mdi-chevron-down"></i></button> <div class="dropdown-menu" aria-labelledby="dropdownMenuButton"> {% for results in showInvestor %} <option> {{results.investor_name}} </option> {% endfor %} </div> </div> </div><!-- end col --> but when I click the drop-down I don't get any entries. What am I doing wrong here? Thanks -
Object doesn't exist in DB after consequential calls
I have the following flow for object creation: A user wants to create an object on a webservice. In order to do it - I check if the user is eligible to pay a fee for it. We make a request to know how much the user should pay. If 0 - user will see the regular Create button, if >0 he will see the PayPal button. User fills in data and in the second case presses the PayPal button. We make 2 consequential API requests: Create an object with the parameter is_draft=True. Return its id. Create an order object and use the id from the previous step. Sometimes we cannot create an order, because the object doesn't exist in DB yet. Django setting: DATABASES["default"]["ATOMIC_REQUESTS"] = True Django models: class Object1(models.Model): name = models.CharField() ... class Object2(models.Model): name = models.CharField() ... class Order(models.Model): user = models.ForeignKey(User) amount = models.DecimalField() #naive polymorphism object1 = models.ForeignKey(Object1) object2 = models.ForeignKey(Object2) # An object will be created after PayPal's call to the webhook endpoint class OrderPayment(models.Model): ... order = models.ForeignKey(Order) The problem is that I cannot call transaction.commit() after any object creation (Object1 or Object2) because I use atomic request and it leads to … -

How to make uWSGI main thread not serve requests for the Django web application?
In my Django application, in the __init__.py, I have a class which spins up an event loop. class X: def __init__(self): self.__loop = asyncio.get_event_loop() async def foo(self): ... def do_stuff(self): # some logic here self.__loop.run_until_complete(foo()) In the __init__.py I just have x = X() In my Django views, I do from myapp import x def example_view(request): result = x.do_stuff() return JsonResponse({"result": result}) But the problem is that with uWSGI, if the thread that serves the request is same as that was used during initialization, I get the Django's SynchronousOnlyOperation exception as it detects a running event loop in that particular thread.
