Where should PWA manifest be located for a Django app?
I'm working on converting a Django app to a Progressive Web App. Where should the manifest file be located in my directory structure if I link to the manifest? I am thinking of: <!-- Startup configuration --> <link rel="manifest" href="{% static 'app_name/manifest.webmanifest' %}"> I was working through the lighthouse plug-in feedback checklist to prep my website for use as a PWA and I ran into the message No usable web app manifest found on page. For Django converting to PWA, is there a preferred convention for this setup? -
Don't submit time past 11:59 pm
I have a form that creates a lesson with a date and time. I currently have validators to ensure that past dates can't be used, which are working perfectly. However, I am having trouble visualising how a validator that makes sure the time entered isn't past 11:59 pm would work. I inlucded a snippet of what I am trying to achieve (I know it doesn't work the way it is layed out, it is just there to provide context). I would appreaciate any help with this. forms.py def validate_date1(value): if value < timezone.now(): raise ValidationError('Date cannot be in the past') def validate_date2(value): if value < timezone.now(): raise ValidationError('Date cannot be in the past') def present_date1(value): if value > '11:59 pm': #raise ValidationError('Time cannot be past 11:59 pm') def present_date2(value): if value > '11:59 pm': raise ValidationError('Time cannot be past 11:59 pm') class LessonForm(forms.ModelForm): lesson_instrument = forms.ChoiceField(choices=instrument_list, widget=forms.Select(attrs={'class' : 'form-control', 'required' : 'True'})) lesson_datetime_start = forms.DateTimeField(input_formats=['%Y-%m-%d %I:%M %p'], widget=forms.DateTimeInput(attrs={'class': 'form-control', 'placeholder':'YYYY-MM-DD Hour:Minute am/pm'}), validators=[validate_date1, present_date1]) lesson_datetime_end = forms.DateTimeField(input_formats=['%Y-%m-%d %I:%M %p'], required=False, widget=forms.DateTimeInput(attrs={'class': 'form-control', 'placeholder':'YYYY-MM-DD Hour:Minute am/pm'}), validators=[validate_date2, present_date2]) lesson_weekly = forms.BooleanField(required=False) -
problem saving records contains foreign key to sqlite3 using Django and Ajax/json

Django NameError: name 'model' is not defined
I am altering an existing application so I can expand the use case a bit. I have already created a new model and altered the view and template a bit. Now I want to run migrations, but I keep getting the NameError and a Google search didn't provide me with much more information, especially since I am adding things to a working application rather than creating something from scratch. Is anyone able to help me?

Django - Show only a specific dynamic fields per models in django-eav2
I'm trying to figure it out on how I can show only a specific set of dynamic fields in eav to a unique registered model in my apps.models. But I don't know how to this, I've also read the documents but I can't seem to find anything about it, or maybe I've come across it and didn't understand. Now, what is happening is that, when I add an attribute in the django admin. It also adds the dynamic field in all the models registered in the eav. What I want to do is that; model 1 - dynamic_field1, dynamic_field2, dynamic_field3 model 2 - dynamic_field4, dynamic_field5, dynamic_field6 Btw, I'm currently using the django-eav2 the documentation is in the link. I've found my solution for my initial use case here link Below codes are basically on how to register my models to the eav. Here is my sample models class ClientName(models.Model): name = models.CharField(max_length=250, null=True, blank=True) description = models.TextField(null=True, blank=True) is_active = models.BooleanField(default=True) def __str__(self): return str(self.name) class CallDetails(models.Model): client_name = models.ForeignKey(ClientName, on_delete=models.PROTECT, null=True, blank=True, db_index=True) letter_info = models.TextField(null=True, blank=True) def __str__(self): return str(self.client_name) class Meta: verbose_name = 'Call Detail' ordering = ['client_name'] eav.register(ClientName) eav.register(CallDetails) below is my admin.py class CallDetailsAdminForm(BaseDynamicEntityForm): model … -

Parsing a string containing logic to create Django Q objects
I'm adding reporting functionality to a django web application which includes being able to chain filters while defining the logic eg (1 OR 2 OR 4) AND 4 Currently the data structure being utilised is: `{'logic': u'(1 OR 2 OR 4) AND 4', 'query': [{u'field': u'first_name', u'id': 1, u'opertor': u'icontains', u'value': u'A'}, {u'field': u'first_name', u'id': 2, u'opertor': u'icontains', u'value': u'b'}, {u'field': u'show_tag', u'id': 3, u'opertor': u'includes', u'value': u'1955'}, {u'field': u'organisation__organisation_name', u'id': 4, u'opertor': u'icontains', u'value': u'a'}]}` To convert the logic from a string to a nested list I'm using the following: from pyparsing import nestedExpr def parse_brackets(val): val = '(' + val + ')' parsed = nestedExpr('(',')').parseString(val).asList() return parsed For the example above this returns [[['1', 'OR', '2', 'OR', '4'], 'AND', '4']] What I'm finding challenging is parsing this data structure so that it can be translated into chained Q() objects. I have tried using BFS to search through the structure but am unable to associate the AND/OR correctly to the surrounding criteria Any advice greatly appreciated! -
django-filter no matches
I couldn't find it in documentation so Im asking here. I've created filter with django-filter and it works properly, but if someone will select filters that none object has, then user will get empty page.

Django is not recognizing my custom user's user type to enter a protected page view (RelatedObjectDoesNotExist: User has no usertype)
I am having issues with Django defining a custom user, which in this case is "cust" (short for customer) in Django 2.1. I have several other user types which contain separate registration forms to register them as a specific user type. I have built this from the tutorial "How to Implement Multiple User Types with Django" by Vitor Freitas, which eliminates Django's default user management system. My goal is to have a protected view (customer hub) which only customers can enter, and so on for other user types. Below is the error and code which comprises my project: Traceback RelatedObjectDoesNotExist at /companyusers/cust/ User has no cust.

django testing: post request with a Form with paramters
I want to test that my view redirects after I send it correct data. The problem is that I'm using a form that needs parameters while initializing. I have a method that builds me a response that I later use in the tests. The method works for my other views but I can't make it work with views that use Forms that need parameters to initialize them. In my forms.py I've got: class SupportIssueForm(forms.ModelForm): class Meta: model = SupportIssue fields = ('user', 'property', 'title', 'text', 'is_urgent', 'is_service') def __init__(self, person_company, properties, is_property, *args, **kwargs): super(SupportIssueForm, self).__init__(*args, **kwargs) self.fields['is_service'].widget.attrs['class'] = 'custom-control-input' ... My method for generating respone I'm later using in my test looks like this: def generate_logged_in_user_post_response(self, data): request = self.factory.post(self.url, data={**self.form_class_args[0], **data}) request.user = self.logged_in_user return new_support_issue_view(request) I also tried this: def generate_logged_in_user_post_response(self, data): form = SupportIssueForm(**self.form_class_args[0], data=data) request = self.factory.post(self.url, form) request.user = self.logged_in_user return new_support_issue_view(request) the self.form_class_args[0] is some dictionary I declare elsewhere: { "person_company": person_company, # <querry object> "properties": properties, # <querry object> 'is_property': False } -

Sourcecode protection of Django application
i know there are already several post about this topic floating around the web but i would like to maybe get some state-of-the-art context here. I want to protect the source code of my django app. primary target is that an attack is not able to properly manipulate source code so i only see two option here. either .py files will get compiled or protected by some kind of third party DRM solution which are indeed in all cases that i know crap... excuse my language but somebody owns the key for that files and i generally trust nobody. Anyway is there a practical solution to accomplish this? Maybe obfuscate and later compile the source to .pyc ? greetz :) -

Omitting password field for custom django user model
I want to have my own custom Django user model with only the email id,first_name, last_name and date_joined fields.I don't want to have a password column since the authentication happens via Microsoft SAML and hence I don't need to store any passwords.My user model is as follows: from __future__ import unicode_literals from django.db import models from django.contrib.auth.models import PermissionsMixin, BaseUserManager, AbstractBaseUser from django.utils.translation import ugettext_lazy as _ class UserManager(BaseUserManager): def _create_user(self, email, **extra_fields): if not email: raise ValueError('The Email must be set') email = self.normalize_email(email) user = self.model(email=email, extra_fields) user.save() return user def create_superuser(self, email, **extra_fields): extra_fields.setdefault('is_staff', True) extra_fields.setdefault('is_superuser', True) extra_fields.setdefault('is_active', True) if extra_fields.get('is_staff') is not True: raise ValueError('Superuser must have is_staff=True.') if extra_fields.get('is_superuser') is not True: raise ValueError('Superuser must have is_superuser=True.') return self._create_user(email, **extra_fields) class User(AbstractBaseUser, PermissionsMixin): email = models.EmailField(_('email address'), unique=True) first_name = models.CharField(_('first name'), max_length=30, blank=True) last_name = models.CharField(_('last name'), max_length=30, blank=True) date_joined = models.DateTimeField(_('date joined'), auto_now_add=True) objects = UserManager() USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['first_name', 'last_name'] class Meta: verbose_name = _('user') verbose_name_plural = _('users') def get_full_name(self): full_name = f'{self.first_name} {self.last_name}' return full_name.strip() However, when i run the migrations, I can see the password field also in the user table.What am i doing wrong ? -

Django rest framework JWT , delete the jwt token
How to expire django rest framework JWT token manually ? Because it does not store the token in the database. Is there any correct way to expire the token ? I am thinking to continue with middleware where token will be stored per user. At every login request we will update the token in the db for a user. At every request, we will fetch the token from request and comapre with the stored token and if doesnt match then we'll return the forbidden. I dont know its a correct way or not !!
