Django Crispy Form doesn't render hidden fields in formsets
I'm using django crispy forms to create inline formsets using a model form and a helper class. In my template, If I do {% crispy entrance_formset entrance_helper %} everything works fine when I submit. But if I try to manually render each form in the entrance_formset like this: {{ entrance_formset.management_form|crispy }} {% for entrance_form in entrance_formset %} {% crispy entrance_form entrance_helper %} {% endfor %} I get the following error when submitting. django.utils.datastructures.MultiValueDictKeyError: "'entrances-0-id'" When I look at the html, I see that the hidden fields entrances-0-idand entrances-1-id are indeed missing. What am I doing wrong? form class: class EntranceForm(ModelForm): latitude = FloatField( min_value=-90, max_value=90, required=False, ) longitude = FloatField( min_value=-180, max_value=180, required=False, ) class Meta: fields = ['name', 'location', 'latitude', 'longitude', 'directions'] widgets = { 'location': HiddenInput, 'directions': Textarea(attrs={'rows': 5}) } def __init__(self, *args, **kwargs): super(EntranceForm, self).__init__(*args, **kwargs) coordinates = self.initial.get('location', None) if isinstance(coordinates, Point): self.initial['latitude'], self.initial['longitude'] = coordinates.tuple def clean(self): data = super(EntranceForm, self).clean() latitude = data.get('latitude') longitude = data.get('longitude') point = data.get('location') if latitude and longitude: data['location'] = Point(latitude, longitude) helper class: class EntranceFormSetHelper(FormHelper): def __init__(self, *args, **kwargs): super(EntranceFormSetHelper, self).__init__(*args, **kwargs) self.layout = Layout( 'name', 'latitude', 'longitude', 'directions', ) self.form_class = 'form-horizontal' self.label_class = 'col-xs-4' self.field_class = … -
Running existing Django project
I am trying to locally run an existing Django project from my own github on a Mac. https://github.com/shanegibney/djangoForum.git Since posting to github over a year ago I've moved to a mac from linux, Fedora. I've been following instructions from, How to run cloned Django project? $ mkdir djangoForum $ cd djangoForum $ virtualenv $ git clone https://github.com/shanegibney/djangoForum.git $ source env/bin/activate $ cd djangoForum $ pip install -r requirements.txt This is where I get the following error, The error is the same whether I use pip or pip3. $ pip --version pip 9.0.1 from /Users/shanegibney/djangoForum/env/lib/python3.6/site-packages (python 3.6) $ python --version Python 3.6.3 The requirements.txt file is here, https://github.com/shanegibney/djangoForum/blob/master/requirements.txt Can anyone see why I get the error when trying to install requirements.txt?

How to mock media file directory in django with custom storage property?
django version: 1.11, python version: 3.6.3 According to this two blogs/articles: https://joeray.me/mocking-files-and-file-storage-for-testing-django-models.html https://www.caktusgroup.com/blog/2013/06/26/media-root-and-django-tests/ we would, ideally, use a temporary directory to upload the mock-files. Now, mocking the files is easy. But mocking the directory and using a temporary directory is not working with custom storage property in settings.py i have a protected root to upload non public images: MEDIA_URL = '/media/' MEDIA_ROOT=os.path.join(BASE_DIR, "cdn", "media") PROTECTED_ROOT = os.path.join(BASE_DIR, "cdn", "protected") in products/models.py i have: from django.conf import settings from django.db import models from django.core.files.storage import FileSystemStorage class Product(models.Model): media = models.ImageField( # custom storage property storage=FileSystemStorage(location=settings.PROTECTED_ROOT) ) and the test in products/tests/test_views.py: from django.test import TestCase from unittest import mock from products.models import Product from django.core.files import File class ProductViewSetup(TestCase): @classmethod def setUpTestData(cls): file_mock = mock.MagicMock(spec=File, name='FileMock') file_mock.name = 'test.jpg' cls.product = Product.objects.create( media=file_mock ) i thought i could just customize the code described in caktusgroup blog to: class TempMediaMixin(object): "Mixin to create MEDIA_ROOT in temp and tear down when complete." def setup_test_environment(self): "Create temp directory and update MEDIA_ROOT and default storage." super(TempMediaMixin, self).setup_test_environment() settings._original_media_root = settings.MEDIA_ROOT settings._original_file_storage = settings.DEFAULT_FILE_STORAGE settings._original_protected_root = settings.PROTECTED_ROOT self._temp_media = tempfile.mkdtemp() self._temp_protected = tempfile.mkdtemp() settings.MEDIA_ROOT = self._temp_media settings.PROTECTED_ROOT = self._temp_protected settings.DEFAULT_FILE_STORAGE = 'django.core.files.storage.FileSystemStorage' def teardown_test_environment(self): "Delete … -
Django doesn't allow to add record to DB due to not table instance
I have a DB model: class building_list(models.Model): building_id = models.CharField(max_length=25, verbose_name="Building ID", unique=True) def __unicode__(self): return self.building_id class data(models.Model): oDate = models.DateField() building_id = models.ForeignKey( building_list, to_field = "building_id" ) content = models.CharField(max_length=25, verbose_name="Content") def __unicode__(self): return self.content There is no problem to add record via Admin Portal, I can choose building_id from SELECT list and everything is okay.

Django context processor doesn't display new context values in template
I'm using Django 1.11 and this is my first time trying to use a custom context processor. The problem is that the context variable I'm supposed to be adding from the context processor does not return anything in the template. I don't receive any errors. I know the context processor file is being executed from some testing. So below {{ testcontext }} should return "IT WORKED!", but returns nothing. Every question I've read on the subject has something to do with the RequestObject not being included in the response, but from what I've read generic class based views are supposed to include RequestObject by default. settings.py: TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [os.path.join(BASE_DIR, 'templates')], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', 'appname.context_processors.test_context', ], }, }, ] context_processors.py: def test_context(request): return {'testcontext': 'TEST WORKED!'} views.py: from django.views.generic import ListView from appname.models import MyModel class MyView(ListView): model = MyModel urls.py from django.conf.urls import url from appname.views import MyView urlpatterns = [ url(r'^$', MyView.as_view(), name="home"), ] template.html {{ testcontext }} -
Organize the checkout page with steps
I have developed a checkout page where a form(guest form and login form) is shown at first if user is not authenticated. When user fills the form, then only the user is redirected to the same checkout page where now he will be shown a shipping address form which when filled will redirect to the same page but now billing address form is shown and after completing that steps, a review is shown.Instead I want to show the steps like Login > Shipping > Billing > Review How can i organize the form or content based on the steps they are in?

Django CMS 3.4 apphooks not "hooking"
I am trying to follow the tutorial here just with my own "app". It's called currencies. cms_apps.py is inside currencies directory and apparently it gets called since I can see the CurrenciesHook in the CMS admin later. However the custom view class is not executed and/or template is not displayed. All I get is a blank page with Django's toolbar at the top and navigation (i.e. what's in base.html template). @apphook_pool.register class CurrenciesHook(CMSApp): name = _("Currencies application") app_name = "currencies" def get_urls(self, page=None, language=None, **kwargs): return ["currencies.urls"] urls.py is also inside currencies dir: urlpatterns = i18n_patterns( url(r'^$', views.DesktopView.as_view(), name="desktop"), ) views.py in the currencies dir has a single class for testing: class DesktopView(generic.TemplateView): template_name = 'desktop.html' and finally template desktop.html inside currencies/templates is simply: {% extends "base.html" %} TEST The command line displays no errors. If you can't tell what may possibly be wrong from the info provided, I'd appreciate any suggestions how to debug this. I'm very new to Django and I last worked with python 5 years ago. -
Django many-to-many through query simplification?

is django db able to have a secondary db set as back up? django
What I am trying to say is, I have two database and they are replicates. Is it possible for django to have settings that if first (primary db) is down / cannot be connected then connect to the second one until the first one is back up? I believe this can be done in server side, but I am wondering if it can be done with django easily instead of touching the db servers? -
Aligning text when converting from html to pdf in django

Running supervisord in AWS Environment
I'm working on adding Django Channels on my elastic beanstalk enviorment, but running into trouble configuring supervisord. Specifically, in /.ebextensions I have a file channels.config with this code: container_commands: 01_copy_supervisord_conf: command: "cp .ebextensions/supervisord/supervisord.conf /opt/python/etc/supervisord.conf" 02_reload_supervisord: command: "supervisorctl -c /opt/python/etc/supervisord.conf reload" This errors on the 2nd command with the following error message, through the elastic beanstalk CLI: Command failed on instance. Return code: 1 Output: error: <class 'FileNotFoundError'>, [Errno 2] No such file or directory: file: /opt/python/run/venv/local/lib/python3.4/site- packages/supervisor/xmlrpc.py line: 562. container_command 02_reload_supervisord in .ebextensions/channels.config failed. My guess would be supervisor didn't install correctly, but because command 1 copies the files without an error, that leads me to think supervisor is indeed installed and I have an issue with the container command. Has anyone implemented supervisor in an AWS environment and can see where I'm going wrong? -

Custom the `on_delete` param function in Django model fields
I have a IPv4Manage model, in it I have a vlanedipv4network field: class IPv4Manage(models.Model): ... vlanedipv4network = models.ForeignKey( to=VlanedIPv4Network, related_name="ipv4s", on_delete=models.xxx, null=True) As we know, on the on_delete param, we general fill the models.xxx, such as models.CASCADE. Is it possible to custom a function, to fill there? I want to do other logic things there.
