How could I submit multiple forms?
How could I submit multiple forms (with the same names) created with for loop? Currently my submit button does nothing at all. Here's my code. {% for key, value in questions.items %} <form action="." method="post"> <div class="question"> {{value.0.question}} {% csrf_token %} {% for answer in value %} <div class="answer"> <input type="radio" name="answer-checkbox" value="{{ answer.id }}"> {{ answer }} </div> {% endfor %} </div> </form> {% endfor %} <input type="submit" value="Save"> -
Blocking unwanted users from access another users profile data with function based view in Django
I am working with some function-based views in Django. I have a custom build decorator named industry_required which allows passing by verifying a user is authenticated from an Industrial account or not. I have some functions in views.py and their particular URL in urls.py. like: in urls.py: path('industryDetails/', views.industryDetails.as_view(), name='industryDetails'), path('industry_create_report/<int:pk>/', views.industry_create_report, name='industry_create_report'), in views.py: @method_decorator(industry_required, name='dispatch') class industryDetails(DetailView): model = Industry template_name = 'app/industryDetails.html' def get_queryset(self): return Industry.objects.filter(user=self.request.user) def get_object(self): return get_object_or_404(Industry, user=self.request.user) def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['inserted_text'] = "inserted text from EmployeeDetails of views.py" context['employee_table'] = self.object.employee_set.all() return context def industry_create_report(request): industry_create_report_dict = { } #bla bla.... return render(request, 'app/industry_create_report.html', industry_create_report_dict) Now my problem is when I use the DetailView, I can easily ensure that which user logged in that user can see only his DetailView profile by using the method_decorator named industry_required and get_queryset and get_object method. But when I use the function-based view, suppose an Industrial account user with pk=1 can also see the data of pk=2 with using URL pattern (industry_create_report/2/), which is not desireable. How can I fix it? -
Bootstrap - how can I push the below element down once the above has grown?
I'm struggling with one thing. I'm iterating objects which create some sort of row table (the new one is always below the previous one). I tried to add footer but the issue arises when I'm displaying more than 18 elements per page, it overlaps it: Example: My html: <body> <div id="main" class="d-flex flex-column h-100"> <div class="container h-100"> {% include 'navbar.html' %} {% block content %}{%endblock%} </div> {% include 'footer.html' %} </div> <script src="{% static 'js/vue2.js' %}" type="text/javascript"></script> </body> How can I make this table to push the footer all the way down depends on its size ? -

How to use Django like a PHP
I need some information about Django. Basically i'm PHP developer. nowadays moving to python with micro services. But i need to know how to handle user authorization in Django. For example, The site have two different users logins. One is front users and another one is site administrators users. The front users have multiple users level and also administrator panel also different levels is there. The front user means like one client, the client have multiple users like employees based on the level the page will available. Coming to admin panel also the site owner also have multiple employees, and the employees also have different roles. Coming to me what was we used in earlier for database table structures is, like Front Users Table: users roles Site Admin Panel Table: admin_users admin_roles In Django have inbuilt administrator panel and also have different level authorization. I'm confused how to handle this. I want to create a users and roles table and want handle sessions in differently or i want use existing Django inbuilt admin users tables??? Please clarify this, it will help me lot and moving further things. Kindle share the links or tutorials related to this. -
Django different filters based on category
I couldn't find a question like mine. Basically, I want to create a complex filtering system.

(Sorry if it's a bit hard to understand I just don't really know how to.) -
python crash course making django posts accessible to unregistered users
Im currently trying to do this exercise of python crash course and am unsure with how to proceed with it. Here is the exercise in question. Then try adding a more advanced feature, such as giving users the option of making a topic public. This would require an attribute called public as part of the Topic model (this should be set to False by default) and a form element on the new_topic page that allows the user to change a topic from private to public. Here are the changes that I have already made so far in forms.py, My understanding is that when the user types in the 'public' text bos either 'True' or 'False', the public attribute of the Topic model will be updated accordingly? from django import forms from .models import Topic, Entry class TopicForm(forms.ModelForm): class Meta: model = Topic fields = ['text', 'public'] labels = {'text': '', 'public' : "True/False"} class EntryForm(forms.ModelForm): class Meta: model = Entry fields = ['text'] labels = {'text': 'Entry:'} widgets = {'text': forms.Textarea(attrs={'cols': 80})} the Topic model in models.py from django.db import models from django.contrib.auth.models import User # Create your models here. class Topic(models.Model): """A topic the user is learning about.""" text … -
Django: Raw SQL Query with parameterized parameters
I'm trying to test the vulnerabilities of SQL injection using the Manager's raw() function in Django. I'm using SQLite as the backend database. I have tried the following two functions for showing the values of the Person Model that I have created. urls.py urlpatterns = [ path('unsafe/<str:user_name>', views.unsafe_get_users, name='unsafe_get_users'), path('safe/<str:user_name>', views.safe_get_users, name='safe_get_users'), ] models.py class Person(models.Model): name = models.CharField(max_length=30) age = models.IntegerField() def __str__(self): return self.name + " " + str(self.age) views.py from django.shortcuts import render from django.http import HttpResponse from .models import Person def unsafe_get_users(request, *args, **kwargs): # sqli using raw user_name = kwargs['user_name'] users = Person.objects.raw('SELECT * FROM member_list_person WHERE name = %s' % user_name) return HttpResponse(users) def safe_get_users(request, *args, **kwargs): # uses parameterized query user_name = kwargs['user_name'] users = Person.objects.raw('SELECT * FROM member_list_person WHERE name = %s', [user_name]) return HttpResponse(users) The Person Model has two fields, namely name and age. As for the unsafe_get_users function, the column data are displayed successfully but for the safe_get_users function, nothing shows up on the server page. I have tried printing len(users), which shows the number of data in the returned RawQuerySet, but for the second one it returns 0 (empty query). Why does unsafe_get_users function return the data as expected … -

Unable to Save to Django Model
I am saving a Django model and everything works except for one column in the model and I can't seem to figure out what the issue is. I imagine just a fresh pair of eyes will see the likely basic error I am making. Here is an abbreviated snippet of my code: My model: class Commission(models.Model): checkout_id = models.CharField(max_length=20,null=True, blank=True) My function: def custom_order(custom_order_manager_data): from apps.commission.models.commission import Commission custom_order_id = custom_order_manager_data['customOrderId'] custom_order_data = Commission.objects.get(id=custom_order_id) custom_order_data.checkout_id = checkout.id #checkout works ignore this print("CHECKOUT ID: ",checkout.id) print("CUSTOM ORDER CHECKOUT Public ID: ",custom_order_data.checkout_id) custom_order_data.save() print("Post Save ",custom_order_data.checkout_id) When I check my logs, everything works and is printing the correct data, but it still isn't saving. Here are the logs: CHECKOUT ID: 3380 CUSTOM ORDER CHECKOUT Public ID: 3380 Post Save 3380 For me this shows that the instance is gathering the correct data and it is saved correct to that instance, but it won't save in the db (all other data does though, it's just specifically when I'm trying to save to checkout_id that isn't working. I am getting no errors. Here is what I've tried: I've changed the model name. I've changed the column name to something more unique. I've increased the … -

How to not submit a form unless search is one of the options (django + HTML) [duplicate]
So I have the following code: <input autocomplete="off" type="search" list="liss" name="q" id="id_q" placeholder="Search"> <datalist id="liss"> <option value="one">Value 1</option> <option value="two">Value 2</option> <option value="three">Value 3</option> <option value="four">Value 4</option> <option value="five">Value 5</option> <option value="six">Value 6</option> </datalist> And it all works fine. The only thing I want it to do is to not let the user submit the form unless the input value is one of the options. How can I do that? -
A way to filter models for ModelChoiceField in Wagtail

How can I do it?
