I'm trying to build a simple Graphql proxy service that receives graphql requests and forwards them to a remote server and I can return the response to the main server. I am using Django for the main project and the remote server is also using Django graphene to return. -
Constant deletion routine can harm the performance of the database or application?
I created a view that does some checks between models as these models are updated/added. When this check finds an inconsistency it creates a record and a specific model of record of inconsistencies. My question is about the strategy I used in this view. view def farm_check(farm_id): farm = get_object_or_404(Farm, pk=farm_id) to_delete = FarmProblem.objects.filter(farm=farm) for delete in to_delete: delete.delete() check_city = Registration.objects.filter(farm=farm).filter(~Q(city=farm.city)) check_uf = Registration.objects.filter(farm=farm).filter(~Q(uf=farm.uf)) check_car = Registration.objects.filter(farm=farm,car__isnull=True) check_ccir = Registration.objects.filter(farm=farm,ccir__isnull=True) check_nirf = Registration.objects.filter(farm=farm,nirf__isnull=True) check_area = Registration.objects.filter(farm=farm,area__isnull=True) list_area_pk = map(lambda x: x.pk,check_area) check_app = Registration.objects.filter(farm=farm,app__isnull=True).exclude(pk__in=list_area_pk) for check in check_city: problem = 'Cidade inconsistente' item_test = FarmProblem.objects.filter(client=farm.client,farm=farm,context='City',specific=check.number,item=problem) if not item_test: item = FarmProblem(client=farm.client,farm=farm,context='City',specific=check.number,item=problem) item.save() for check in check_uf: problem = 'UF inconsistente' item_test = FarmProblem.objects.filter(client=farm.client,farm=farm,context='UF',specific=check.number,item=problem) if not item_test: item = FarmProblem(client=farm.client,farm=farm,context='UF',specific=check.number,item=problem) item.save() for check in check_car: problem = 'CAR inconsistente' item_test = FarmProblem.objects.filter(client=farm.client,farm=farm,context='CAR',specific=check.number,item=problem) if not item_test: item = FarmProblem(client=farm.client,farm=farm,context='CAR',specific=check.number,item=problem) item.save() for check in check_ccir: problem = 'CCIR inconsistente' item_test = FarmProblem.objects.filter(client=farm.client,farm=farm,context='CCIR',specific=check.number,item=problem) if not item_test: item = FarmProblem(client=farm.client,farm=farm,context='CCIR',specific=check.number,item=problem) item.save() for check in check_nirf: problem = 'Sem número de NIRF' item_test = FarmProblem.objects.filter(client=farm.client,farm=farm,context='NIRF',specific=check.number,item=problem) if not item_test: item = FarmProblem(client=farm.client,farm=farm,context='NIRF',specific=check.number,item=problem) item.save() for check in check_area: problem = 'Área indeterminada' item_test = FarmProblem.objects.filter(client=farm.client,farm=farm,context='Area',specific=check.number,item=problem) if not item_test: item = FarmProblem(client=farm.client,farm=farm,context='Area',specific=check.number,item=problem) item.save() for check in check_app: problem … -

Django view function isnt working correctly
so the basic goal of my project is to allow teachers and admin to login to the system and take attendance for the students. my new issue is that i have a view function that is suppose to check to see if students student is already added to the respective class and if they are it will exclude them from the drop down menu and display the students who aren't in the class but it not doing that instead it is showing me a blank drop down menu. the way i have it set up is that the admin clicks the add student button then it will convert a .html page to modal which brings up the list of students to select from. When i add the form responsible for saving the student to the class in the Django admin it work perfect but i cant seem to get it to work in the user section Ui. I am new to Django and this is my first project so any help is really appreciated Views #check to see if students already exist in class and display those who aint to be added @login_required def manage_class_student(request, classPK=None): if classPK is None: … -
Creating a subForm within a Form to populate an Abstract Form
I have been trying to figure this out by banging my head and scouring the forums and Google. Hope someone has had experience with this. I am trying to create some text mining subform within PostForm Class that calls a script.So an user enters a DOI or PMID and searches the PUBMED database.I am successful with the script pulls data from a server, but would like to figure out the user then continues to fill the rest of the data. So together with the Called data and the User entry save as post. Here I am using the Django-Machina Blog as the platform. So a User would enter a DOI or PMID, returns a query, that a user can then enter information in contents. [Form][1] AbstractModel: class AbstractPost(DatedModel): """ Represents a forum post. A forum post is always linked to a topic.

Django Generating Custom ID
Okay so, I have seen numerous "answers" to this question, most notably, this one. from django.db.models import Max id = models.CharField(primary_key=True, editable= False, max_length=10) def save(self, **kwargs): if not self.id: max= Custom.objects.aggregate(id_max=Max('id'))['id_max'] self.id= "{}{:05d}".format('IT-', max if max is not None else 1) super().save(*kwargs) Now, thanks to this, I really just apply the code to my model, and it should work. Well, it doesn't. It wants to, but it can't, let me explain: on the backend of the django application I tried adding a new row, but when saving it, it throws an OperationalError, (1366, "Incorrect integer value: 'IT-00002' for column id), (my prefix being 'IT-'). Now, from what I can gather, the prefix is being included yes, but the column isn´t changing from integer. I have saved, migrated all changes and it isn´t working. I have even tried changing the data type in phpmyadmin, but because it also has the 'AUTO_INCREMENT' property, it can't be changed to anything other than an integer. How can I change this? -

Django import export get() returned more than one

I am able to properly export from the admin site into csv files using resources and ForeignKeyWidget from import_export.

Django DELETE Endpoint gives permission denied, but every other endpoint works fine

Django List Sending To API
We are currently in the process of making a new online store program for our students. The current framework we are using is DJANGO. On one of our views which is called completed checkout, it sends an email to the student's counselor to approve the following purchase. That email we are sending via 3rd party is called Postmark. The reason we decided to go with the third party as opposed to Django is to monitor the tracking of the emails and not have to deal with SMTP issues. The API is a REST API and requires JSON, dictionary, or list to be sent to populate the template. I'm going to show you the postmark template in HTML. The following lines within the template are what the API pushes data to. <td width="60%" class="align-left purchase_item">{{product__name}}</td> <td width="40%" class="align-right purchase_item">{{product__point_price}}</td> Template <table class="purchase_content" width="100%" cellpadding="0" cellspacing="0"> <tr> <th class="purchase_heading"> <p class="align-left">Description</p> </th> <th class="purchase_heading"> <p class="align-right">Amount</p> </th> </tr> {{#each receipt_details}} <tr> <td width="60%" class="align-left purchase_item">{{product__name}}</td> <td width="40%" class="align-right purchase_item">{{product__point_price}}</td> </tr> {{/each}} <tr> <td width="80%" class="purchase_footer" valign="middle"> <p class="purchase_total purchase_total--label">Total Points</p> </td> <td width="20%" class="purchase_footer" valign="middle"> <p class="purchase_total">{{points}}</p> </td> </tr> </table> Now below here is the Completed Checkout View.
