Saleor Stripe integration shows only one payment method (card) while in test mode
I enabled the Stripe implementation for Saleor. I added the correct api-keys. The connection is working. But Saleor only shows 1 of multiple payment methods provided by Stripe. I am working in testmode so I expect all payment methods to be shown. Stripe marks them also with 'testmode' in their own environment. Someone had this problem before? Can't find any documentation about this problem. -

Where to make a loop in templates(index.html) of django?
There are two div for two columns. I want to make a loop in it so that I don't have to repeat. I tried a loop above the section tag then after section tag but it is not working.

Sort through linked model with ForeignKey
I need to do a sorting of the Credit records through the associated models of CreditPayment. models.py class Credit(models.Model): hot = models.BooleanField(default=False) class CreditPayment(models.Model): credit = models.ForeignKey(Credit) period_to = models.PositiveIntegerField() rate = models.DecimalField(max_digits=7, decimal_places=2) views.py credits = credits.filter(hot=False).distinct().order_by(...) Example of input data: Credit #1: CreditPayment #1: period_to = 12 rate = 10 CreditPayment #2: (minimal) period_to = 10 rate = 8 CreditPayment #3: period_to = 9 rate = 10 Credit #2: CreditPayment #1: (minimal) period_to = 6 rate = 20 CreditPayment #2: period_to = 9 rate = 20 Credit #3: CreditPayment #1: period_to = 12 rate = 8 CreditPayment #2: period_to = 9 rate = 11 CreditPayment #3: (minimal) period_to = 9 rate = 8 As a result, the sample is reduced to: Credit #1: CreditPayment #2: period_to = 10 rate = 8 Credit #2: CreditPayment #1: period_to = 6 rate = 20 Credit #3: CreditPayment #3: period_to = 9 rate = 8 Result: Credit #3 -> Credit #1 -> Credit #2 As you can see, at first the minimum CreditPayment was selected for each Credit (credits at views.py). Then, according to these minimum CreditPayment, allCredit is sorted. If the rate of two or more entries are equal, compare byperiod_to. … -

Sending files as an attachment Django
I have created an XLS file and want to send it as an attachment to an email. The following code is working fine and I receive an email with the XLS file (status code is 200 OK). # This is working code import xlwt import StringIO import zipfile from django.core.mail import EmailMessage work_book = xlwt.Workbook() # Here some boring stuff with excel ... report_name = "do_something_%(username)s_%(current_date)s.xls" f = StringIO.StringIO() work_book.save(f) message = EmailMessage( subject=u"Sample Title", body=u"Sample body", to=["test@company.com"]) message.attach(report_name, f.getvalue()) message.send() But if I try to send compressed XLS file (using zipfile), i don't receive anything (However status code is "200 OK"). I replaced the last 2 lines of code with the following: report_name_zip = 'do_something_%(username)s_%(current_date)s.zip' with zipfile.ZipFile(f, mode='w', compression=zipfile.ZIP_DEFLATED) as zf: zf.writestr(zinfo_or_arcname=report_name, bytes=f.getvalue()) message.attach(report_name_zip, f.getvalue()) message.send() -
Django serialize one field only instead of whole model in related fields (readonly)
I'd like to serialize a nested model field that only has one field by using the field of the nested model directly. Following code should explain the situation: # models class Tag(models.Model): title = models.CharField(max_length=255, unique=True) class Scene(models.Model): title = models.CharField(max_length=255, unique=True) tags = models.ManyToManyField(Tag, blank=True) # serializers class SceneSerializer(serializers.ModelSerializer): class Meta: model = Scene fields = ('id', 'title', 'tags',) read_only_fields = ('tags',) which outputs the following if used: { "id": 1, "title": "yolol", "tags": [ 1, 2 ] } What I'd like to have is the following output (using Tag.title instead of the primary key): { "id": 1, "title": "A Scene", "tags": [ "3D", "Industry" ] } How do I write a serializer that does this for the tags? -

Django 1.11 showing Warnings message
When I'm running a Django test server locally with ./manage.py runserver, lots of warnings are showing up (DeprecationWarning, RemovedInDjango20Warning), even if they shouldn't be there by default (https://docs.djangoproject.com/en/2.2/releases/1.11/#deprecating-warnings-are-no-longer-loud-by-default). I've put this code in a Django command : import warnings warnings.simplefilter("ignore", DeprecationWarning) warnings.simplefilter("ignore", RemovedInDjango20Warning) and it's hiding the warnings on that command, but I don't know where to put it so that it hide all warnings globally (I've tried in manage.py, settings.py, models.py,...) I've also tried to run python -W ignore manage.py runserver which is supposed to tell python not to show warnings, but it still display a lot of warnings. Warnings look like that : /.../venv/lib64/python3.6/site-packages/review/templatetags/review_tags.py:11: RemovedInDjango20Warning: assignment_tag() is deprecated. Use simple_tag() instead @register.assignment_tag or /.../models/results.py: RemovedInDjango20Warning: on_delete will be a required arg for ForeignKey in Django 2.0. Set it to models.CASCADE on models and in existing migrations if you want to maintain the current default behavior One possibility would be to update Django version and make all change suggested by warnings but it would be too long and I just want to hide those warnings. -
