how to receive modelform_instance.cleaned_data['foreign key field'] in view when form field is ModelMultipleChoiceField?
Here is the situation: I have a model as below: class School(Model): name = CharField(...)

django how to transfer sum value to another model field each time user input is happened
enter image description herei want to transfer the sum value of stok_masuk as total_masuk,which then it will become the value of another model. The problem is,aggregate sum can only update the value to the same model. Which is why i make onetoonefield for the other model. But the value is not the accumulated total, but still a piece that must be chosen manually by admin, not automatically because this code is not working. def t_masuk(self): jaya = Pergerakanstokgudangatas.objects.aggregate(Sum('stok_masuk')) jaya.save(update_fields=['total_masuk']) return self.t_masuk def t_keluar(self): joyo = Pergerakanstokgudangatas.objects.aggregate(Sum('stok_keluar')) joyo.save(update_fields=['total_keluar']) return self.t_keluar The expected result would be,in picture 45454545, the total value of stok_masuk and stok_keluar will become a value as total_masuk and total_keluar in another fieldenter image description here -

How to convert uploaded html file to pdf? (django rest framework)
I have already made html file template in the frontend, and by sending it to the backend I want it to be converted and saved as pdf, I'm newbie in django but I did tried some searching, here's what I found : https://www.codingforentrepreneurs.com/blog/html-template-to-pdf-in-django/ , If I go with this approach, it will be unnecessary to get multiple data from the user, since the form is very detailed, and frontend is enough to fill. I also did this approach but I don't know what I am missing (https://www.codingforentrepreneurs.com/blog/save-a-auto-generated-pdf-file-django-model) , here is my code so far: (utils.py) from io import BytesIO from django.http import HttpResponse from django.template.loader import get_template from xhtml2pdf import pisa def render_to_pdf(template_src): # template = get_template(template_src) # html = template.render(context_dict) result = BytesIO() pdf = pisa.pisaDocument(BytesIO(template_src.encode("ISO-8859-1")), result) if not pdf.err: print(pdf) return HttpResponse(result.getvalue(), content_type='application/pdf') return None //============= (models.py) class Questionary(models.Model): date = models.DateField(auto_now_add=True) title = models.CharField(max_length = 100) file = models.FileField(upload_to='Documents/%Y/%m/%d/', blank = False, null = False) def generate_obj_pdf(self): obj = Questionary.objects.get(file=self.id) pdf = render_to_pdf(obj) filename = "YourPDF_Order{}.pdf" %(obj.title) return obj.pdf.save(filename, File(BytesIO(pdf.content))) I expect the html file to be auto converted to pdf, but it still saving it as html. -
Migrate data from django-media-tree to django-filer
We have a DjangoCMS with more than 1000 pages that has been live for many years now and we have been using django-media-tree for a long time, but have now also installed django-filer. I would now like to migrate all of my files from django-media-tree and into django-filer and at the same time, migrate the usage of the files (plugins in articles), so that I eventually can uninstall django-media-tree and make the site look the same for the end user. Has anyone tried to do this and perhaps have some pointers? Maybe someone has written a tool for this already? Regards, Erlend Dalen -

Django - FileField won't upload to database

Custom authentication in djangorestframework-jwt
I have two types of user. for one of them which is main user that it's model is available from get_user_model() is ok and the endpoint for that is: Import: from rest_framework_jwt.views import obtain_jwt_token path: path("api/token/", obtain_jwt_token, name="user_jwt") http://127.0.0.1:8000/users/api/token/ Everything is pretty find when I provide my main user credentials for generate token. but for the other type user Teacher it needs some changes in djangorestframework-jwt core codes. I know that it uses username as the default field to login. for main user is Ok, because it takes that this way: username_field = get_user_model().USERNAME_FIELD that in this case is email. I've defined that in model. but for the other type of user it tries to get username this way: def get_username(user): try: username = user.get_username() except AttributeError: username = user.username return username that because the user doesn't have get_username() attribute, because It's a regular model and does not inherit from any model. so I need to edit: username = user.username to username = user.email now when I refer to the custom authentication method it generates the token. but for access/request methods that need Authentication It returns 401 Unauthorized, Invalid signature. What is the problem? How should create a custom authentication … -
Atomic transactions in Django app in a for loop
In my django app I have a celery task which handles user-uploaded XLS file. Its being used to do something like "mass import" of data. In for loop I am processing each row - from each row I want to create one model instance object (so I will have multiple Model.objects.create(...) calls - for one row its possible that I will create multiple objects and its foreign keys). Is is possible in django to have an atomic transaction for whole for-loop? For example, if XLS contains 100 rows - and 90 of them are successful but 91 is not (because data in row is wrong) - is it possible to rollback previous 90 (or more) DB saves? My code looks like: workbook = xlrd.open_workbook(importobject.file.path) worksheet = workbook.sheet_by_index(0) processed_rows = [] omitted_rows = [] print('Mass import rows: ', worksheet.nrows) startrange = 0 if str(worksheet.cell(0, 0).value) == 'header': print('Omit first row as header row') startrange = 1 for rowno in range(startrange, worksheet.nrows): logger.info('Processing row {}:'.format(rowno)) for colno in range(worksheet.ncols): cell = worksheet.cell(rowno, colno) print('Row {}, Col {}:'.format(rowno, colno), str(cell.value)) # process call and row # validate and save object here - if not valid - rollback whole mass import #MyModel.objects.create() -

Using inlineformset_factory with different querysets in CreateView

Problem with custom django admin listview editable field
Django 2.1.2 I've almost successfully added a checkbox to a django admin listview which doesn't link to a field in the underlying model. Instead I want to update fields in the model based on the checkbox value. My code's almost working after reading a post here. My problem is that if I override save() in my form, django breaks somewhere else saying that "'NoneType' object has no attribute 'save'". I have a TrainingSession model with a submitted_date and an accepted_date. The below code shows a checkbox in the listview which defaults to checked if accepted_date is set, and the checkbox is disabled if submitted_date is not set. My plan is then to set the accepted_date to today if you check the checkbox: class TrainingSessionListForm(forms.ModelForm): accept = forms.BooleanField(required=False) class Meta: model = TrainingSession fields = '__all__' def __init__(self, *args, **kwargs): instance = kwargs.get('instance') if instance: initiallyApproved = instance.accepted_date is not None submittedForApproval = instance.submitted_date is not None initial = kwargs.get('initial', {}) initial['accept'] = initiallyApproved self.base_fields['accept'].disabled = not submittedForApproval kwargs['initial'] = initial super(TrainingSessionListForm, self).__init__(*args, **kwargs) def save(self, *args, **kwargs): instance = kwargs.get('instance') if instance: accepted = self.cleaned_data['accept'] if accepted and instance.accepted_date is None: instance.accepted_date = datetime.date.today() super(TrainingSessionListForm, self).save(*args, **kwargs) class TrainingSessionAdmin(admin.ModelAdmin): list_display … -
