What does a parameter without equal in a django models.Field means?
I was reviewing a django repo in git hub and find this way of fields declaration from django.utils.translation import ugettext_lazy as _ class Usuario(AbstractBaseUser, PermissionsMixin): usuario = models.CharField(_('Usuario'), max_length=60, unique=True) is_staff = models.BooleanField(_('staff status'), default=False) I don't understand for what is the _('Usuario') and _('staff status') parameters. Could someone explain me this? Thanks -

Trying to query based on choice field django
I've been stuck on this all day. I've got a model, Load, within that model it has a choice field with different "statuses". I am trying to implement some tabbed views in my template. So basically each tab will be responsible for displaying a certain status. I believe that I should be using a queryset within my view get_context_data but I'm just not really understanding how to accomplish this. I've tried a ton of different ways in the view, so i'll just paste the latest attempt. These query's will be static once they are done so my best thought was to use a model managers for each query, but I couldn't get multiple model managers to work on one model. Here's an example of one. Any help would be appreciated.

Django Formset Redirect with pk/id
I'm trying to pass in the parent id of a formset into a view, but it doesn't seem to work for me for some reason. I do this in other apps without issue but this particular one returns "None" as a pk.

django core 'dict' object is not callable
Django 2.0.1 python 3.6.3 Hi I have an address form which is a kind of extended user model form. The form asks for name, birth-date, address and phone info. I do some form validation on the form fields, for example the birth-date entered must be at least 18 years ago. I also overwrite the form's clean method to verify the US address via the USPS address api. After the address info is verified the validated/normalized address values returned from the USPS are put into the cleaned_data dict and are returned. After the cleaned_data return, Django eventually calls _get_response() in django/core/handlers/base.py. There is a section ... if response is None: wrapped_callback = self.make_view_atomic(callback) try: response = wrapped_callback(request, *callback_args, **callback_kwargs) except Exception as e: response = self.process_exception_by_middleware(e, request) that throws the error: TypeError at / 'dict' object is not callable What does that mean in this context? -
Django groups and permissions in API level (with django-rest-framework)
Consider the following scenario; I have a bunch of Users and API classes. I need to restrict access to each API by checking the requested user's group permissions and allow the user to do group permitted stuff. Suppose I have a user user_xx, he belongs to group group_xx and has permissions activity | activity | Can add activity. When user_xx tries to access MyActivityAPI through HTTP-DELETE method the view class should restrict the access.Can do I achieve this feature? If possible, How?What I'd triedCreated some groups & assigned permissions to them and added users to their corresponding groups. I tried to access one of the restricted api, but it allows me to access (expected behaviour : restrict the user from the api). -

Nested and Integrated Crispy Layouts
TLDR Question: How do you make one crispy form with an ¿integrated?(not sure if this is considered inline) layout with multiple models(some related, some not). I am trying to understand several things in Django: forms, formsets, nested forms, and crispy, and I've been at it for a while, and feel I am close, just need someone to help connect the dots. I'm not sure how to accomplish it without crispy, so I started down this path thinking crispy was the solution. Please correct if I am wrong, thanks :) I would like one form (as in HTML form, not necessarily Django Form), that has a primary model with lots of fields, but with secondary/tertiary models in the middle of the primary fields. I am somewhat near the layout, but can't seem to get the secondary/tertiary models to render in the middle of the layout, let alone compile (at the bottom) without crispy/django erroring. Here is what I am trying to attain Files For reference models.py #Black in the picture class Truck(models.Model): name = models.CharField(…) … #Blue in the picture class QuickInspection(models.Model): odometer = models.IntegerField(…) … (created_at, user_cookie#who did it, …) truck = models.ForeignKey(Truck) ----- #These two are unrelated to the … -

Deploying SSL for my Django 2.0.1 server with Apache on Ubuntu 16.04 (droplet)

How to deploy Django without mod_wsgi
I'm relatively new to web development, but I have a couple years experience working with python, so I figured I would build my first production site using django. I've spent the last few days learning the basics and building a test site running on my local machine. Today, I've been trying to deploy my site to production; however, I've hit a pretty large stumbling block. The django documentation suggests using mod_wsgi for apache deployments. I followed the install instructions here, only to realize that I don't have access to make any changes to apache - I'm currently on a shared hosting plan. Apparently, to perform the install, I would have to upgrade to a VPS plan, which costs a lot more. Any advice for a new web developer trying to get a proof-of-concept web app together (preferably with feedback gathered from real users) on a budget? I think I have two options: Eat the cost on my current web hosting plan. Try to find a cheaper host that specializes in django hosting. I've been looking at the following (suggestions here would be wonderful): Heroku DigitalOcean A2Hosting Try some sort of manual deployment. Is this possible or has anybody ever made … -

I've set up a cookiecutter-django project for testing and it worked just fine printing the confirmation email to the console. However, it's important to me to also test the actual sending of the emails and when I tried to adjust the settings for a local testing environment, it gave me a "SMTP AUTH extension not supported by server." error after adding a new account. I changed EMAIL_BACKEND to EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' and added the relevant EMAIL_HOST, EMAIL_PORT, EMAIL_HOST_USER, and EMAIL_HOST_PASSWORD settings in the local.py settings file. I'm using a yahoo account that was set up for this purpose and worked just fine outside of Django. I can't find anything in the cookie-cutter documentation about how to configure this and the Django documentation has been less than helpful. -
Django REST framework, dealing with related fields on creating records
Preliminary note: this is a rather newbie question, though I have not found a sufficient answer on StackOverflow; many similar questions, but not this one. So I am asking a new question. The problem: I'm having difficulty creating records where one field is a foreign key to an existing record, and I do not know what I'm doing wrong in my code. In my app there are two models in question, a one-to-many relationship between Company and BalanceSheet: models: class Company(models.Model): cik = models.IntegerField(default=0, unique=True) symbol = models.CharField(max_length=4, unique=True) name = models.CharField(max_length=255, unique=True) def __str__(self): return self.symbol class BalanceSheet(models.Model): company = models.ForeignKey(Company, null=True, on_delete=models.CASCADE, related_name='balance_sheets',) date = models.DateField() profit = models.BigIntegerField() loss = models.BigIntegerField() class Meta: unique_together = (('company', 'date'),) def __str__(self): return '%s - %s' % (self.company, self.date) serializers: class BalanceSheetSerializer(serializers.ModelSerializer): company = serializers.StringRelatedField() class Meta: model = BalanceSheet fields = ('company','date','profit','loss') class CompanySerializer(serializers.ModelSerializer): class Meta: model = Company fields = ('cik', 'symbol', 'name') Views: class BalanceSheetCreate(generics.CreateAPIView): '''Creates a company in the database''' model = BalanceSheet queryset = BalanceSheet.objects.all() serializer_class = BalanceSheetSerializer urls include: url(r'^(?P<symbol>[A-Z]{1,4})/create-balance-sheet/$', views.BalanceSheetCreate.as_view(), name='create_balance_sheet'), To this point, I have zero problem reading data. However, when trying to create records, I get errors I don't understand: curl …
