Django, Celery and Sequential Asynchronous tasks
I am building a system in Django that uses Celery and Django-Celery-Beat to run data creation and extraction tasks. I am pulling records from a datastore using it's API and from this creating multiple jsonl files as the final output - these files become the basis for all the subsequent tasks. Then images are made using information from the jsonl files and then these files are used to update other systems (namely Solr). All this works fine. It's the Celery part that has me stummped. These tasks need to be run sequentially and they each can't fail, and if they do the sequence needs to stop. I also need to lock the tasks from running twice as this will mess up the jsonl files, image creation, etc.... What I have looked into is using Celery and chains with immutable signatures, as the tasks don't return anything, they create files, images, etc.... But I can't seem to find a method to lock the tasks from running twice at the same time. So the questions has two parts What is the best method for running periodic tasks in Django that needs to run asynchronously but also sequentially within that task? Is Celery … -
Customizing inlineformset choice in Django template
I've got some forms I'm trying to customize. I render the fields manually - and it all works fine until get to a particular field (which is an InlineFormset itself). I'm trying to customize those options but can't seem to figure out how to do so. my forms.py looks like this: class SummativeScoreForm(forms.ModelForm): subdomain_proficiency_level = forms.ModelChoiceField( empty_label="Undecided", queryset=SubdomainProficiencyLevel.objects.none(), widget=forms.RadioSelect, required=False, ) def __init__(self, request, *args, **kwargs): super(SummativeScoreForm, self).__init__(*args, **kwargs) if self.instance: if request.user == self.instance.summative.employee: self.fields["subdomain_proficiency_level"].disabled = True self.fields[ "subdomain_proficiency_level" ].queryset = SubdomainProficiencyLevel.objects.filter( subdomain=self.instance.subdomain ) self.fields[ "subdomain_proficiency_level" ].label = f""" {self.instance.subdomain.character_code}: {self.instance.subdomain.short_description} """ class Meta: model = SummativeScore fields = "__all__" SummativeScoreInlineFormset = inlineformset_factory( Summative, SummativeScore, fields=("subdomain_proficiency_level",), can_delete=False, extra=0, form=SummativeScoreForm, ) My template for summative_score_form looks like this: <form method="post" novalidate> {% csrf_token %} {% include "myapp/includes/summative_score_response_formset_snippet.html" with formset=form %} <button type="submit" class="btn btn-primary"><i class="fal fa-clipboard-check"></i> Submit Updated Scores</button> </form> The summative_score_response_formset_snippet looks like this: {{ formset.management_form }} {% for formset_form in formset.forms %} {% if formset_form.non_field_errors %} <ul> {% for error in formset_form.non_field_errors %} <li>{{ error }}</li> {% endfor %} </ul> {% endif %} {% for hidden_field in formset_form.hidden_fields %} {% if hidden_field.errors %} <ul> {% for error in hidden_field.errors %} <li> (Hidden field {{ hidden_field.name }}) {{ error … -
Django rest don't see json data of GET XmlHTTPRequest
Recently, i have started playing with django rest framework, my goal is to perform a GET on a rest api with some kind of filtering. For this i have choose to pass filters params as json object. I do this with xmlhttprequest. The problem is the django side don't see my json data when i dump the request. I have try this method with curl and it is ok. But from code, it is not. I have dumped the http headers and see that the only valuable diff is that Content-Length is not set with xmlhttprequest, contrary to curl. I have tried to set it manually but it is refused by javascript engine, he say 'Refuse to set dangerous header', after digging into the internet, this look to be forbidden. I have tried to change to the POST method, and this time, it work, i see my filters data. So my question is, is there a settings, decorator, flag or whatever that can force httprequest to parse content data h when content-length is absent for GET request ? Thanks -
How to paginate different objects of the same endpoint in Django Rest Framework?
Lest supose that I have a model named Collection. I can create a collection, this collection have two important fields: share_with_company, share_list. class Collection(models.Model): name = models.CharField(max_length=200, blank=False, null=False) share_with_company = models.BooleanField(default=False) share_list = ArrayField(models.CharField(max_length=15), null=True, blank=True) owner = models.CharField(max_length=200, blank=False, null=False) currently I have an endpoint: /collections and this endpoint need to return something like it: { shared_with_company:{collections: ..., count: 5} shared_list:{collections: ..., count: 12} my_collections:{collections: ..., count: 20} //dont shared with anyone, created by the current user } but, in the frontend the user want to paginate just my_collections or just shared_list or shared_with_company. I like performance, so should I create a specifics endpoints to each type of collections? But, everytime the user load the collections page will show 12 (max per page) collections of each (my_collections, shared etc.), and then he will be able to paginate it. I don't know if this is the best way to do it, I think a lot of users send 3 requests everytime the page is loaded. Another approach: use an endpoint to load the initial page, and this enpoint will make one request to the first page and the paginations will be made with differents endpoints. I really don't know … -
Django displaying each object in a button
Good day, I have a page to test where tickets are created and where all created tickets (titles) are listed. Now you should be able to click on the title of a created ticket. The button then redirects to an extra page where all the information of the specific ticket is. I've always had trouble displaying user specific stuff, so what needs to be done so that the href="" of each link redirects in HTML to the specific ticket? I did the following \\forms.py {% for i in request.user.addtitle_set.all %} <div> {% if i.user == request.user %} {{ i.title }} {% endif %} <form action="{% url SOMETHING_HERE i.id}" style="display: inline"> <button type="submit">Delete</button> </form> </div> <br /> {% endfor %} \\urls.py path('dashboard/user/ticket', ticket_view), path('dashboard/user/ticket/<int:id>/', ticket_system_view, name="view_ticket"), \\ models.py class Ticket(models.Model): user = models.ForeignKey( settings.AUTH_USER_MODEL, default=None, null=True, on_delete=models.CASCADE, ) title = models.CharField(max_length=200) description = models.TextField() creator_adress = models.GenericIPAddressField(null=True) start_date = models.DateTimeField(default=timezone.now) def __str__(self): return str(self.title) \\views.py @login_required def ticket_view(request, id, *args, **kwargs): try: obj = Ticket.objects.get(id=id) except Ticket.DoesNotExist: return redirect('/') if request.method == 'POST': form = TicketForm(request.POST, instance=Ticket(user=request.user)) if form.is_valid(): obj = form.save(commit=False) obj.creator_adress = get_client_ip(request) obj.save() return redirect('/dashboard/user/ticket') else: form = TicketForm() return render(request, 'ticket.html', {'form': form}) def ticket_system_view(request, id, *args, … -

Django handling database table names differently in Ubuntu vs Windows
I've built a Django application locally and I'm now trying to deploy it (or at least test) on an AWS EC2 instance using Ubuntu 20.04 (t2.micro). When hosted locally, the application works fine. When hosted on AWS, I get a ProgrammingError (1146, "Table 'database_name.exampleAppName_modelname' doesn't exist"). What I've tried On the server, using MySQL in the command line I've done: USE database_name; SHOW tables; Which lists tables as expected as: +----------------------------------------------+ | Tables_in_database_name | +----------------------------------------------+ | auth_group | | auth_group_permissions | | auth_permission | | auth_user | | auth_user_groups | | auth_user_user_permissions | | django_admin_log | | django_content_type | | django_migrations | | django_session | | **exampleappname_modelname** | The cause of the error seems to be fairly obvious in that Django is querying 'exampleAppName' but the database contains 'exampleappname' instead. However, when I run the same MySQL commands locally, I get exactly the same list of tables. And when I run the Django app locally there are no errors. I checked the names Django is automatically assigning the tables on the server and locally using the shell: ModelName._meta.db_table In both cases, this returns: 'exampleAppName_modelname', which leads to my question. What I'd like to know If the 'db_table' name auto-assigns the … -

Celery delay task gets called twice but triggers only once
I am trying to run a celery task with multiple files. Simply put in a for loop I am calling the delay method on the task and I know that it gets called because I can see the logs before being called. However, the action inside the task itself gets executed only once. in my code I have something like this: def operation(*args, **kwargs): for arg in *args: time.sleep(2) # 2s interval celery_task.delay(kwargs) And the task actually look like this @shared_task(bind=True) def celery_task(**kwargs): do_something() # async So my question is: is there some kind of check that I can't see that prevents multiple tasks to be sent, or does it have something to do with different threads?

How to make a django api view accessible to all users?

The button <button class="btn btn-info" data-toggle="modal" data-target="#note-update-modal">Update</button> Then on the form for updating the post, i pass inn the post id, but it does not get the post id. the form, further down the html, that open up, when the update button is pressed <form method="POST" action="{% url 'update_notes' note.id title.slug %}" class="modal fade" id="note-update-modal" tabindex="-1" aria-hidden="true"> This form updated the post, but not the given post that the button presses, only takes the last posted post. I need a way to pass the id from the button, that is pressed to open the form, so that the form get the right id. Is there a way to do this? If somehow the question is not making sense please write, and yes the update function, the view, urls, everything work, it is just to get the right post. -
Django DigitalOcean Apps Deployment
I have a very small application that I am working on. I have everything up and running locally but can't get it deployed to DigitalOcean Apps. I have re-read all the tutorials and just can't get past this one spot. See the error below ModuleNotFoundError: No module named 'dj_database_url' So I have manually created the static file directories in the project, I ran the python manage.py collectstatic --noinput command locally and it did its job and put the files in the STATIC_ROOT directory. I also changed things out and the module name will change based on the order of the requirements.txt I really have no idea what I can do to fix this. Any help would be greatly appreciated. It feels like it is a really simple fix but I don't know what it is. -
