best Error handling with csv reader in django
So I've got a small application, and I am uploading bulk data via CSV reader. Everything uploads great, provided I go through my CSV with a fine comb. The only issue is the error handling. Whether it works or fails, I get a 500 error page. Then I have to look through the data base to find at what point the CSV reader failed or compare row count to ensure all values went through. Here is the code for my view: def admin_calv_csv(request): template = "calves/admin_calv_csv.html" prompt = { 'order': 'Order should be eid, visual_id, dairy_id, dob, ship_in_date, ship_out_date, slug, sex, breed, destination, medical_history, milk_consumed, program,' } if request.method == "GET": return render(request, template, prompt) csv_file = request.FILES['file'] if not csv_file.name.endswith('.csv'): messages.error(request, 'This is not a CSV') data_set = csv_file.read().decode('UTF-8') io_string = io.StringIO(data_set) for _ in data_set: try: next(io_string) for column in csv.reader(io_string, delimiter=','): _, created = Calf.objects.update_or_create( eid=column[0], visual_id=column[1], dairy_id=column[2], dob=column[3], ship_in_date=column[4], ship_out_date=column[5], slug=column[6], sex=column[7], breed=column[8], destination=column[9], medical_history=column[10], milk_consumed=column[11], program=column[12], ) except IntegrityError as e: error_message = str(e.__cause__) messages.error(request, error_message) test = str(_) messages.info(request, 'error on' + _) pass context = {} return render(request, template, context, messages) -
Handling 2 Django forms - passing data from one to the other

I want these words to be looped through and added to a database table(where each row is a word), then have the second form reference these words. Views.py # upload_id = (request.GET.get("id")) if request.method == 'POST': form = UploadForm(request.POST, request.FILES) if form.is_valid(): form.save() data = request.FILES['docfile']#.read().decode('UTF-8') words=get_keywords(data) results=list(find_skills(words)) for word in results: form2 = Resume_words(word = word, word_type='exclude', upload = upload_id) form2.save() return render(request, 'word_list.html',{ "results":results }) else: form = UploadForm() return render(request, 'upload.html', { 'form':form }) I having trouble pulling these pieces together and I'm desperate for help of any kind!

How do I query data from the database base on user in a completely separated frontend Django REST
So I have this basic model: class Text(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) title = models.CharField(max_length=255) def __str__(self): return self.title so usually when you're using regular Django and you want to query Text from the database based on the user you would do: def main_page(request): userTexts = Text.objects.filter(user=request.user) context = {} return render(request, '', context) but now I've been using Django REST React stack and built a completely separated frontend and the only way I access the data from the backend is by making HTTP request to it, so now request.user wont work anymore because it's just going to return anonymousUser fortunately though I already have an authentication system working and already have a user object inside my react state all I have to do is design a view and an API call to query the data from the backend but I cant imagine how to do both of those things. -
Django Queryset filter array field by exact string
so I haven't been working with Django for too long. I am running into a problem filtering a queryset by the exact name of a string of arrays that is passed into it. Currently, I am filtering the queryset by icontains, which works. For example the current implementation works like this: If I pass in one string called "test" my queryset will be filtered and show deals with tags "test1" "test2" and "test3". This is not what I want. I want to filter by the exact name of the strings that are passed in. So if I have a "test" as one of the strings then my queryset will only search for test, not anything that is contained into it. I've tried multiple implementations, such as switching from icontains to iexact, and exact. Goal. Filter queryset by array of multiple tags. old query: values is an array of tags (strings) that are passed in values = value.replace(" ", "").split(",") return qs.filter(reduce(operator.or_, (Q(tags__iontains=item) for item in values))) What I have tried: I have tried passing in the iexact with the list of values like below. I have also tried just passing iexact, and then passing in only one hardcoded string from … -
How to restrict access by group membership, roles, and ID in Django using class-based views
I'm a relative newbie, working on a Django directory-based app that serves many companies, and I want to know best practices/standards for restricting access by company-membership, user ID, and user role. The app is structured so that a company manager (CM) has superuser-like permissions for that company only, and then company team members (CTM) may or may not have restricted permissions to modify pages specific to that group/company only. The public user needs to be able to access the company's pages so companies are separated using their slug in the url. So company "A"'s home page is found by example.com/A/home. Using LoginRequiredMixin effectively restricts access to only logged-in users but logged-in users can be of the following types in this app: a public member, an app admin (like myself), a company manager, a company team member. I need to make sure of the following: 1) the logged-in user belongs to the company that is trying to be accessed (ie if I am a public user or belong to company "B" I cannot access company "A" restricted pages simply by being logged in and entering the slug in the url), 2) the logged in user has necessary permissions, even if the … -

Reducing the number of queries in a Django app using a raw query
Objects of MyClass have associated history table that is populated by the database triggers, so not under control of the application. Current code has a method to query the history: class MyClass: @classmethod def history_query(cls, id): query = f'select * from history_table' if id: query = f"{query} where id='{id}'" def history(self): return MyClass.objects.raw(self.history_query(self.id)) The problem is when I list all the objects, the history table gets queried once for every object, creating thousands of queries... I'm trying to speed up the sluggish application by changing this to one query. Here's my current attempt: class MyClass: _full_history = None @classmethod def history_query(cls, id=None): query = f'select * from history_table' if id: query = f"{query} where id='{id}'" def history(self): if self._full_history: return self._full_history[self.id] return MyClass.objects.raw(self.history_query(self.id)) @classmethod def history_by_id(cls): if cls._full_history is None: history_list = MyClass.objects.raw(cls.history_query()) history_dict = {} for item in history_list: id = item.id history_dict[id] = history_dict.get(id, []) history_dict[id].append(item) cls._full_history = history_dict return cls._full_history Is there a better or more efficient way to do this? Would it be possible to do it with prefetch? -

I tried every thing but nothing works, this is my Nginx Configurations: server { listen 443 default_server ssl; server_name www.elamanecc.com.dz elamanecc.com.dz; ssl_certificate /etc/nginx/ssl/www_elamanecc_com_dz/ssl-bundle.crt; ssl_certificate_key /etc/nginx/ssl/www_elamanecc_com_dz/www_elamanecc_com_dz.key; # Logs access_log /home/elamancc/logs/nginx_site1/access.log; error_log /home/elamancc/logs/nginx_site1/error.log; location = /favicon.ico { access_log off; log_not_found off; } location /static/ { root /home/elamancc/commerce/pre/pre-elamanecc; } location /media/ { root /home/elamancc/commerce/pre/pre-elamanecc; } location / { proxy_set_header Host $host; #include proxy_params; proxy_pass http://unix:/run/ccenamale.sock; } client_max_body_size 7M; } If I set ssl off; as some mentioned in other solutions, then it will redirect me to http and display this message (I don't want http, I only want https works) : Welcome to nginx! If you see this page, the nginx web server is successfully installed and working. Further configuration is required. For online documentation and support please refer to nginx.org. Commercial support is available at nginx.com. Thank you for using nginx. -
Django ForeignKey.limit_choices_to with ForeignKey to ManyToMany scenario
I have a complex relation scenario as shown below. I'd like limit_choices_to Questions that are related to JobChecklistAnswer.job_checklist.checklist on JobChecklistAnswer.question. How can I filter those Questions as Q object (or callable as the docs say)? class Checklist(models.Model): name = models.CharField(_("name"), max_length=150) description = models.CharField(_("description"), max_length=150) class Question(models.Model): checklist = models.ForeignKey(Checklist, on_delete=models.CASCADE) question = models.CharField(_("question"), max_length=200) class Job(models.Model): ... ... class JobChecklist(models.Model): job = models.ForeignKey(Job, on_delete=models.CASCADE) checklist = models.ForeignKey(Checklist, on_delete=models.CASCADE) class JobChecklistAnswer(models.Model): job_checklist = models.ForeignKey(JobChecklist, on_delete=models.CASCADE) # FIXME: Add limit_choices_to query question question = models.OneToOneField(ChecklistItem, on_delete=models.CASCADE) answer = models.TextField(_("answer"))
