Django - What are the advantages and disadvantages of using unique_togueter vs. using a queryset in the view?
Suppose we have the next model: class Publications(models.Model): author = .......... post = .......... and we don't want duplicate records to be stored in the database. This could be done with unique togheter on the model: Meta: unique_together = (author, post) or it could be done in the view with something like: register_exist = Publications.objects.filter(...).exists() if register_exist == False: #Code to save the info What are the advantages or disadvantages of using these methods? -
Django 2.2.6 (Python 3.6) + Apache + Ubuntu 18.04.3 error
I made a django project and I tried deploying it with apache and wsgi, however I'm getting the following error in error.log: Current thread (most recent call first): [Wed Dec 04 17:14:02. 2019] [core:notice] [pid :tid ] AH00051: child pid 27347 exit signal Aborted (6), possible coredump in /etc/apache2 Fatal Python error: Py_Initialize: Unable to get the locale encoding ModuleNotFoundError: No module named 'encodings' I'm using python 3.6.9, I've installed every necessary library using pip3 and I've installed ibapache2-mod-wsgi-py3 using apt.

What is the correct way to get translations from Django's *.po/mo files?
Currently I activate each language and then use ugettext but it looks ugly. from django.conf import settings from django.utils.translation import activate, ugettext # settings.LANGUAGES looks like: settings.LANGUAGES = [ ('en', 'English'), ('ru', 'Russian') ] class Profile(models.Model): ACTIVE = 1 INACTIVE = 2 CLOSED = 3 PROFILE_STATUS_CHOICES = ( (ACTIVE, _('Active')), (INACTIVE, _('Inactive')), (CLOSED, _('Closed')), ) def choices_serialize(choices): """ Convert choices to format suitable for Front End's tree-select. :param choices: :return: [{'id': 1, 'text': {'en': 'Active', 'ru': 'Действующий'}}, {'id': 2, 'text': {'en': 'Inactive','ru': 'Недействующий'}}, {'id': 3, 'text': {'en': 'Closed', 'ru': 'Закрыт'}}] """ data = {} for lang in [t[0] for t in settings.LANGUAGES]: activate(lang) for choice in choices: data.setdefault(choice[0], {}) data[choice[0]].setdefault(lang, ugettext(choice[1])) return [{'id': k, 'text': v} for k, v in data.items()] choices_serialize(Profile.PROFILE_STATUS_CHOICES) Is there a better approach? -
Parse Data into HTML Bootstrap modal (Django)
I have downloaded a bootstrap theme. In one of the HTML documents there is a modal. Basically a Popup that contains like a detail page. My question is how I can parse data into that detail page from the specific object I tapped. So some kind of id. Before I used to have the detail page on a separate page. Through a URL I did this: {% url 'URL' object.id %}. This is a part of the modal and lets say I want to change the modal-title depending on the object.id: <div class="modal modal-task" id="task-modal" tabindex="-1" role="dialog" aria-hidden="true"> <div class="modal-dialog modal-lg" role="document"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title">Create Brand Mood Boards</h5> This is the loop of cards, all with different urls: When I tap one the detail pop-up shows. And I want the data of that card inside the pop-up. like a detail view: <div class="modal modal-task" id="task-modal" tabindex="-1" role="dialog" aria-hidden="true"> <div class="modal-dialog modal-lg" role="document"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title">Create Brand Mood Boards</h5> Here are the cards: This is the pop-up: -
How to require dependent drop down whenever there are options to choose from in Django?
I have a form with a dependent drop-down. Currently, I have it set so that the second drop-down only appears if there are options available in it, otherwise is hidden. What I am having trouble with is that, whenever you choose a primary(Work Area) option that has a secondary(Station) drop-down, you can submit the form without having selected an option from the dependent (secondary) drop-down, which is supposed to be required whenever there are options in it. How can I modify this so that the dependent drop-down is required whenever it appears? models.py class WorkArea(models.Model): name = models.CharField(max_length=50) def __str__(self): return self.name class Station(models.Model): work_area = models.ForeignKey(WorkArea, on_delete=models.CASCADE, related_name="stations") name = models.CharField(max_length=50) def __str__(self): return self.name class EmployeeWorkAreaLog(TimeStampedModel, SoftDeleteModel, models.Model): employee_number = models.ForeignKey(Salesman, on_delete=models.SET_NULL, help_text="Employee #", null=True, blank=False) work_area = models.ForeignKey(WorkArea, on_delete=models.SET_NULL, null=True, blank=False, help_text="Work Area", related_name="work_area") station_number = models.ForeignKey(Station, on_delete=models.SET_NULL, null=True, help_text="Station", related_name="stations", blank=True) forms.py class WarehouseForm(AppsModelForm): class Meta: model = EmployeeWorkAreaLog widgets = { 'employee_number': ForeignKeyRawIdWidget(EmployeeWorkAreaLog._meta.get_field('employee_number').remote_field, site, attrs={'id':'employee_number_field'}), } fields = ('employee_number', 'work_area', 'station_number') def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['station_number'].queryset = Station.objects.none() if 'work_area' in self.data: try: work_area_id = int(self.data.get('work_area')) self.fields['station_number'].queryset = Station.objects.filter(work_area_id=work_area_id).order_by('name') except (ValueError, TypeError): pass elif self.instance.pk: self.fields['station_number'].queryset = self.instance.work_area.stations.order_by('name') views.py def enter_exit_area(request): enter_without_exit = … -

See all the items created by the logged in user
novice here trying to get an ebay style e-commerce project finished! When a user checks their profile, I want it to list all the items they have for sale. The owner in the Item model stores the username, so, essentially, I want to check the owner field of all items, then pull the ones that are == username. Here's the code I got so far: views.py def user_profile(request): """The users profile page""" user = User.objects.get(email=request.user.email) user_items = Item.objects.filter(owner__icontains=request.GET[user]) return render(request, 'profile.html', {"profile": user, "items": user_items}) I'm then using {% for item in user_items %} in the html. Apologies if this is an easy one, but I'm struggling to get this right. -

Why is my dependent drop down disappearing upon submission?
I have a form with a dependent drop down. Whenever the form is submitted, only the first field is cleared, if the drop downs were filled out, they remain the same. I have the dependent dropdown set to appear only when there are options available, but after the form gets submitted with an option that has a secondary option, only the first dropdown renders, because it does not load the dropdown logic until you select a new option and go back to what you had. For a more visual understanding: This is the form when the page first loads When you select an option that has secondary options, the other dropdown appears After you select a Station and submit, the Employee # clears, but the other two remain, however, when the page reloads upon submission, it looks like this And when I look at the data that remained in the form, only the work area stayed, because the dependent dropdown does not load until you select another option from the drop down, and if you wanted to be able to see the Box Assembly options again, you'd have to click another option and then go back to Box Assembly (for … -

Django: Access num_pages in view to generate pagination
I want to generate a range of pages in my template when using a ListView and it's pagination, to generate dynamically the number of pages for the pagination: https://getbootstrap.com/docs/4.0/components/pagination/ My first attempt was to make a for loop for everyelement in page_obj.paginator.num_pages, getting error int is not iterable: {% if is_paginated %} <ul class="pagination"> {% for i in page_obj.paginator.num_pages %} <li class="page-item"> <span class="page-link"> <a href="/catalogo?page={{i}}"> <span class="sr-only">(current)</span> </span> </li> {% endfor %} </ul> {% endif } Then I've discovered that there isn't and wont be a range template filter because this calculation should be done in the view and send the range to the template, not generated in the template. See: https://code.djangoproject.com/ticket/13088 So how can I access the page_obj.paginator.num_pages inside the view??? My LisView: class CatalogoListView(ListView): model = UnitaryProduct template_name = "shop/catalogo.html" paginate_by = 10 def get_queryset(self): filter_val = self.request.GET.get('filtro', 'todas') order = self.request.GET.get('orderby', 'created') if filter_val == "todas": context = UnitaryProduct.objects.all().filter(available=True).order_by('-created') return context else: context = UnitaryProduct.objects.filter( subcategory2=filter_val, ).filter(available=True).order_by('-created') return context def get_context_data(self, **kwargs): context = super(CatalogoListView, self).get_context_data(**kwargs) context['filtro'] = self.request.GET.get('filtro', 'todas') context['orderby'] = self.request.GET.get('orderby', 'created') context['category'] = Category.objects.get(slug="catalogo") return context -
Docker app server ip address 127.0.0.1 difference of 0.0.0.0 ip
He everyone. I'm working with docker and trying to dockerize a simple django application that does an external http connect to a web page (real website) so when I set in the Docker file the address of my django server that should work in the container - 127.0.0.1:8000. my app wasn't working because of the impossibility to do an external connection to the website. but when I set the port for my server: 0.0.0.0:8000 it started to work. So my question is: Why it behaves like that? What is the difference in this particular case? I just want to understand it. I read some articles about 0.0.0.0 and it's like a 'generic' or 'placeholder' port that allows to use the OC default port. 127.0.0.1 is like a host that redirects the request to the current machine. I knew it. But when I run the app at my localmachine (host: 127.0.0.0:8000) everything was working and the app could do the connection to the real website but in case of docker it stopped to work. Thanks for any help! Here are my sources: Docker file FROM python:3.6 RUN mkdir /code WORKDIR /code COPY requirements.txt ./ RUN pip install --no-cache-dir -r requirements.txt COPY … -

How to make a field read-only inside a CreateView
I am a Django beginner and I am trying to make read-only a 'price' field for an order. I think, based on what I have understood, this cannot be done inside the model itself, but rather inside a form. Since I am using a CreateView generic view, I thought this could have been done by setting the attribute disabled equal to True, as said here. so what I have done is, in views.py from django.shortcuts import render from django.views.generic import CreateView from .models import Order from django import forms # Create your views here. class CreateOrderView(CreateView): model = Order template_name = 'home.html' meal_price = forms.DecimalField(disabled=True) fields = [ 'meal_name', 'meal_price', 'restaurant', 'customer', ] But this doesn't work. Here is my models.py from django.db import models from restaurant.models import Restaurant from account.models import Customer # Create your models here. class Order(models.Model): meal_name = models.CharField(max_length=255) meal_price = models.DecimalField(max_digits=5, decimal_places=2) restaurant = models.ForeignKey(Restaurant, on_delete=models.CASCADE, default=None) customer = models.ForeignKey(Customer, on_delete=models.CASCADE, default=None) Can anybody give me a hint? Please consider that I am still learning so I would prefer coded answers to descriptive ones. Thank you in advance -

Django Admin Forms validate child form based on parent values
What I'm trying to do is validate a nested_admin.NestedTabularInline form based on some parent data. (If a parent field is one value check if a child field is blank). But I'm having trouble finding a good solution. I've tried using self.data, but it seems incredibly difficult to parse reliably. I've also seen use of FormSet to access other forms, but I'm not sure how to apply it in my case. A simple example looks like: model.py Parent(models.Model): type = models.CharField(max_length=256) Child(models.Model): value = models.IntegerField() items = models.CharField(max_length=256) admin.py @admin.register(models.Parent) class ParentAdmin(nested_admin.NestedModelAdmin): inlines = [ChildInline] class ChildInline(nested_admin.NestedTabularInline): form = forms.ChildInlineAdminForm model = models.Child forms.py class ChildInlineAdminForm(forms.ModelForm): def __init__(self, *args, **kwargs): super(ChildInlineAdminForm, self).__init__(*args, **kwargs) def clean(self): cleaned_data = super().clean() # How can I access the parent instance type field here??? I really feel like there should be a straightforward solution I'm missing, but I haven't found it yet so help would be greatly appreciated. -
