UnboundLocalError at / local variable 'Profile' referenced before assignment?
How to solve this issue of UnboundLocalError at /profile/ local variable 'context' referenced before assignment. I am seeing it to be okay? When I remove Payment_method dropdown menu,, it works but why it is not working with dropdown menu? models.py Paymet_choices = ( ('easypaisa','EasyPaisa Number'), ('jazzcash', 'Jazzcash Number'), ) class Profile(models.Model): payment_method = models.CharField(max_length=6, choices=Paymet_choices) forms.py class ProfileUpdateForm(forms.ModelForm): class Meta: model = Profile fields = ['image','Payment_method','Detail'] views.py def profile(request): if request.method == 'POST': u_form = UserUpdateForm(request.POST, instance=request.user) p_form = ProfileUpdateForm(request.POST, request.FILES, instance=request.user.profile) if u_form.is_valid() and p_form.is_valid(): u_form.save() p_form.save() messages.success(request, f'Your account has been updated!') return redirect('profile') else: u_form = UserUpdateForm(instance=request.user) p_form = ProfileUpdateForm(instance=request.user.profile) context = { 'u_form': u_form, 'p_form': p_form } return render(request, 'users/profile.html', context) -
Django model translation
What is the best way to have model fields translated in Django? I've thought about adding extra fields to the model (one field for language) or creating another model with all texts in every language, is there a recommended way to achieve that? Thank you very much -
How to override a package method in Django?
I'm trying to override a parent class method that I've installed via pip. But, the problem is that I'm not sure how my overridden class will be called so that it will use my method instead of parent class method. This is the method I'm trying to override: class OIDCAuthenticationBackend(ModelBackend): def verify_claims(self, claims): """Verify the provided claims to decide if authentication should be allowed.""" # Verify claims required by default configuration scopes = self.get_settings('OIDC_RP_SCOPES', 'openid email') if 'email' in scopes.split(): return 'email' in claims LOGGER.warning('Custom OIDC_RP_SCOPES defined. ' 'You need to override `verify_claims` for custom claims verification.') return True And my overridden method is : models.py from mozilla_django_oidc.auth import OIDCAuthenticationBackend class MyOIDCAB(OIDCAuthenticationBackend): def verify_claims(self, claims): return True I've written this on models.py according to some docs I read for overriding but I'm not sure where should I actually write this. then trying to call it from my view functions like this: views.py from myapp import MyOIDCAB but then I got this error: from myapp import MyOIDCAB ImportError: cannot import name 'MyOIDCAB' I'm not sure I'm calling it in the right way or wrong? My project structure is: myproject myapp templates manage.py -

Django sessions: How to include session ID in every log record?
I would like to include session ID (at least portion of it) in every log entry in Django. This would help me group together logs for each user session in case several users are interacting with my Django API at the same time. I know I can retrieve session ID from Request object (when it exists) but I would have to do so for every logger.info() across the whole framework. Instead it would be much better to have Request somehow available in settings.py so that I can prepend the ID to my formatter's format string inside LOGGING config. This would ensure that the session ID is included in every log entry and I would not need to think about it in every view or serializer, etc. But I haven't found a way how to make Request or Session available in settings.py. -
Django - update dictionary with missing date values, set to 0
So to display a small bargraph using Django and Chart.js I constructed the following query on my model. views.py class BookingsView(TemplateView): template_name = 'orders/bookings.html' def get_context_data(self, **kwargs): today = datetime.date.today() seven_days = today + datetime.timedelta(days=7) bookings = dict(Booking.objects.filter(start_date__range = [today, seven_days]) \ .order_by('start_date') \ .values_list('start_date') \ .annotate(Count('id'))) # Trying to add 0 for the missing start_date within the range for start_date in (seven_days): if start_date not in bookings: bookings.update({start_date : 0}) context['booking_list'] = bookings This led me to the following result; { datetime.date(2019, 8, 6): 12, datetime.date(2019, 8, 7): 12, datetime.date(2019, 8, 9): 4, datetime.date(2019, 8, 10): 7, datetime.date(2019, 8, 12): 7 } To use the data in a chart I would like to add the missing start_dates into the dictionary but I'm not entirely sure how to do this. So I want to update the dictionary with a value "0" for the 8th and 11th of August. I tried to add the for statement but I got the error; "'datetime.date' object is not iterable" -
Why does Form submit data by POST only once in a while and then it shows an empty POST dict?
I have a simple form which asks the user to confirm Delete by clicking on Yes or No . The Yes/No (radio buttons with hidden inputs) are attached to a function which immediately submits the form on click of either of the buttons via POST. The Problem is that on submit , the POST data is shown empty , and page redirects to home page without any action . I am building it on Django 2.2. I tried changing the radio buttons to text inputs and then assigning values to them on click of Yes/No and submit the form . That too shows an empty POST Data . But yes , once in a while it works , but then it doesn't . <form method='POST' action="/{{user}}/{{del_id}}/delete"> {% csrf_token %} <h2>Confirm Delete ?</h2> <h3> {{to_delete}} </h3> <img src="" alt="" class="thumb-square"> <br> <br> <p class="center-text">This won't be recovered</p> <label id='no' data-value='Yes' class="danger-btn" onclick="submitForm(this.id)">Yes</label> <input type="text" name='Yes' id='Yes' hidden> <label id='yes' data-value='No' class="success-btn" onclick="submitForm(this.id)">No</label> <input type="text" name='No' id='No' hidden> <input type="submit" value="Delete" id='submit' hidden> </form> JavaScript <script> function submitForm(elem) { console.log(elem); var x = document.getElementById(elem); console.log(x); document.getElementById(elem).value = x.getAttribute('value'); document.getElementById('submit').click(); } </script> I want that the request.POST['Yes'] should have a value of 'Yes' … -
Django: How to prompt user during migration?
I'm writing a migration that converts a ForeignKeyField to a ManyToManyField. Part of this migration involves data migration. Migrating forwards is easy and requires no user interaction. Migrating backwards however ideally requires the user to pick which of the m2m to become the foreign key (ie there's a recognition of data loss). Additionally. the user performing the migration might want to be given a python shell so they can poke around and look at objects before answering the question. And some users might not care, and might not want to be prompted at all. (ie they use the --no-input argument during migration) Does django have a built in mechanism to do all this? I can't find anything, but at the back of my mind it seems like something I've seen somewhere. -

How to display django message after uploading an image in form?
I created a simple django html page which enables a user to upload an image. If the image format is either PNG, JPG, JPEG or SVG, it should display a message called "Image uploaded successfully" and save the file in the directory. But, if it's any other format apart from this, it should give a message: "Unsuccessful, please upload either in PNG, JPG, SVG or JPEG". How do I display the message? I tried using the SuccessMessageMixin but it displays the message for both success and failure uploads. Please do help.

DRF: How to limit fields in nested serializer based on field-permissions?

Is there 3rd party software for storing and displaying, but not processing payment information?
My business (travel agency) must accept payment from a customer, then broker the payment directly to the travel provider (say, a cruise line). The providers do not have API's, and it is not customary (nor financially viable) to actually process the payment to our own merchant account. This means customers supply us with card information which we have to store, queue to accounting, then remit the payment to the supplier. We are currently producing an in-house proprietary software package for the business. We need to have this functionality, but we would like to issue private keys to only a handful of local machines capable of decrypting the data to plain text. The back end is powered by Django and most of the modules it supports are to a VUE.JS front-end application. Is there an established approach for doing this? Are there any 3rd party providers we could off load this to? All of the 3rd parties I see are only for processing the payment, not to view it later in plain text to remit to an entirely different vendor. None of the major travel providers accept payment cooperation with Stripe or any such 3rd party. -

Django : Fetch application User Model for multiple application from Central Database
Django : I have 6 applications which are already live but they have their own user database table and Model(All have different field names and they have their own extra column.Now I have to go and add user in every application. I have one Idea that I can create cron job which syncs data to current database from central database, but still I have to maintain all local database. Can I use something like singleton class and remove applications user database and sync user object once from central database and use that? I am new to django and I would welcome any suggestions or any implementation sample.
