Django printing many to many children not in same order as input
I have a tour model with a many to many relationship with Places both models are defined as : class Tourguide(models.Model): id = models.AutoField(db_column='ID', primary_key=True, unique=True) title = models.CharField(db_column='Title', max_length=255, blank=True) places = models.ManyToManyField(Place, db_column='placesdj') created_on = models.DateTimeField(db_column='Created_On', default = now) class Meta: managed = False db_table = 'tourguide' def __str__(self): return self.title class Place(models.Model): place_id = models.AutoField(db_column='ID', primary_key=True) place_name = models.CharField(db_column='Place_Name', max_length=255) address_line_1 = models.CharField(db_column='Address_Line_1', max_length=255) address_line_2 = models.CharField(db_column='Address_Line_2', max_length=255) area = models.CharField(db_column='Area', max_length=255) class Meta: managed = False db_table = 'Place' def __str__(self): return self.place_name - THE PROBLEM When i try to print the places in a tourguide using : {% for place in tour.places.all %} <tbody> <td>{{ forloop.counter }}</td> <td>id: {{place.place_id}}, {{ place.place_name }} </td> <td> {{ place.description }} </td> </tbody> {% endfor %} The order of the places is all random and not the same as the order i inputed it as. i want to print the places in the same order that i placed them in.

Hiding fields with Django crispy forms

Is it possible to have two ManyToMany relationships to the same model on the same admin page?
I modelling a quiz and the associated questions as follows: # models class Question(models.Model): title = models.TextField() category = models.TextField() class Quiz(models.Model): questions = models.ManyToManyField(Question, through='OrderedQuestion') class OrderedQuestion(models.Model): # A through table to allow ordering of questions question = models.ForeignKey(Question, ...) quiz = models.ForeignKey(Quiz, ...) order = models.PositiveIntegerField(default=0) I have two types of questions that are handled by proxy models: # proxy models to handle specific question categories class BoatQuestion(Question): objects = BoatQuestionManager() # handles setting category class Meta: proxy = True and a similar one for CarQuestion. I want to be able to edit BoatQuestions and CarQuestions independently from each other but on the same admin page. The admin setup is: class BoatQuestionInline(admin.TabularInline): model = BoatQuestion.quiz.through class CarQuestionInline(admin.TabularInline): model = CarQuestion.quiz.through class QuizAdmin(admin.ModelAdmin): model = Quiz inlines = (BoatQuestionInline, CarQuestionInline) but whenever I change the questions in the boat question section, the questions in the car section update to match it and vice versa. Is there any way to show these on the same admin page but change them independently? -
Never cache js for development
I am using django runserver for development and I often find that the javascript file that I am using is being cached. It's almost impossible to tell when it's being cached unless I add alert or console.log statements every time I make a change to see if that's actually been "picked up". Is there a setting in django to never cache the static files when running on localhost? Or is this something that has to do with my browser (Chrome) instead? What I am doing now as a hack, is each time I make a javascript change I change v1 in my script tag. <script src="{{ STATIC_URL }}js/settings.js?v1"></script> -
Django: Patch a call in get_context_data of a FormView
I am trying to understand how patching works and I am testing with pytest a Django View: views.py from django.contrib.auth.views import LoginView class MyLoginView(LoginView): pass test_view.py from django.test import RequestFactory from .views import MyLoginView rf = RequestFactory() def test_login(rf): request = rf.get(reverse('myapp:login')) response = MyLoginView.as_view()(request) assert response.status_code == 200 This fails because this View calls the database in order to get the current Site using the function get_current_site(): Failed: Database access not allowed How can I mock get_current_site to avoid the database hit? I got an idea, try to use a factory with pytest-factoryboy: from django.test import RequestFactory from .views import MyLoginView from django.contrib.sites.models import Site from pytest_factoryboy import register from unittest.mock import patch rf = RequestFactory() class SiteFactory(factory.Factory): class Meta: model = Site register(SiteFactory) def test_login_social(rf, site_factory): request = rf.get(reverse('myapp:login')) with patch( 'django.contrib.sites.shortcuts.get_current_site', return_value=site_factory(name='example.com'), ): response = CommunityLoginView.as_view()(request) assert response.status_code == 200 The result is the same: Failed: Database access not allowed How would you do it? -

Django models vs raw SQL queries
I'm working on my senior design project, and I've got some questions about Django that I'm having trouble finding the answers to. If these questions have been answered before, please just point me in the right direction because my searches weren't turning up anything. The general scope of the project is a website that interfaces with a database. I'm personally responsible for developing the DB as well as writing some API to make it easier on my team, who is less familiar with SQL base languages. I've already built a prototype of my database in mysql, but I later found out that Django's implementation of database integration uses models, and it looks it ultimately replaces the mysql implementation. Since I've already built the database, should I redesign it with Django or am I safe to continue only using raw queries? Are there any significant security concerns to be aware of if I decide to forgo the model method of implementation? Thanks in advance for your advice! -
Django Taggit Through Model
Say we have this Django Scenario: We have a model class instantiating home appliances (fridges, tvs, cooktops...) and we need to add classified tags to it. By classified tags, I mean that the tags should be grouped by criteria like "color", "voltage", "technology"... My approach to this using django-taggit required creating a custom tag class like described below. class HomeAppliance(models.Model): name = models.CharField(db_index=True, max_length=100) ## Fridge Bosch Frost Free Inox... ##fields here... tags = TaggableManager(through=TaggedModels) ## inox, frost free... class TaggedHomeAppliance(TaggedItemBase): content_object = models.ForeignKey('HomeAppliance', on_delete=models.CASCADE) filteringCriteria = models.ManyToManyField("FilteringCriteria") class FilteringCriteria(models.Model): name = models.CharField(max_length=100) ##color, voltage, technology My question here is how should I add tags to my model like this: frigde.tags.add('inox', 'frostfree') and have these tags properly assigned to my filtering criteria. In other worlds, how my TaggedHomeAppliance instance can correctly find out which filter criteria my tag should be added to, or how should I pass this information while adding my tags to the model. Thanks in advance, Felipe. -
DRF Router issue with namespace
I am having a hell of a time getting the reverse function to work with my DRF implementation. Here is my urls.py, which i would assume the following reverse to work for: urls.py from django.conf.urls import url, include from rest_framework import routers from . import views router = routers.DefaultRouter() router.register(r'compressors', views.CompressorViewSet, base_name='compressors') from django.urls import include, path # Wire up our API using automatic URL routing. # Additionally, we include login URLs for the browsable API. urlpatterns = [ url(r'^', include(router.urls, namespace='router')), url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework')) ] And then reverse('router:compressors', kwargs) What am I missing? I am getting a app_name not provided, which when added to this file does not help. Is there a way for me to put an app_name to the router? -
How to connect Google API with Django?
In a project, I have to retrieve google contacts for each user. Here the user is authenticated with Google social API. Is there a way that whenever the user wants to access his contacts, he would be asked to authorize the app and then the app server can access his contacts. -
How can I migrate after removing model "hidden" in my Django Models?
I created a hidden input in my models.py: hidden = models.BooleanField(default=False) and proceeded to makemigrations and migrate my changes. After doing so, I decided to remove it and so i went and deleted the same line and did makemigrations although this time I got an error ending along the lines of: File "/opt/django/www/local/lib/python2.7/site-packages/Django-1.8-py2.7.egg/django/db/backends/utils.py", line 64, in execute return self.cursor.execute(sql, params) File "/opt/django/www/local/lib/python2.7/site-packages/Django-1.8-py2.7.egg/django/db/backends/mysql/base.py", line 124, in execute return self.cursor.execute(query, args) File "build/bdist.linux-x86_64/egg/MySQLdb/cursors.py", line 205, in execute File "build/bdist.linux-x86_64/egg/MySQLdb/connections.py", line 36, in defaulterrorhandler django.db.utils.OperationalError: (1091, "Can't DROP 'hidden'; check that column/key exists") Did I handle the situation incorrectly? -

Python3/Django - QuerySet not updating
I'm creating a website that allows for the creation of events, and those events will be shown on both the home page, and on the events list, so that people can click on the events on view the descriptions of them, as well as check in at the event. I'm having an issue getting a query set within a class to update when a new event is added. So this function is for our main home page. The query_set updates every time you go back to the page, so when a new event is added, it is shown on this page. def index(request): num_future_events = Event.objects.filter(date__gte=today).filter(approved=True).count() query_set = Event.objects.filter(date__gte=today).filter(approved=True).order_by('date', 'time')[:3] context = { 'num_future_events': num_future_events, 'query_set': query_set } return render(request, 'index.html', context=context) This is a class for the events list page on my site. It uses a query set but since the class is only ever called once, the query set will only update with the class's initialization. class EventListView(generic.ListView): model = Event query_set = Event.objects.filter(date__gte=today).exclude(approved=False).order_by('date', 'time')[:21] template_name = 'listPage.html' def get_queryset(self): return self.query_set I was hoping to get some help with making it so when a new event is added, the query set in the EventListView class updates automatically … -
combine django user with many-to-many model for display organized by user and other fields
I have a django model that represents a calendar event: class Event(models.Model): title = models.CharField(max_length=120) date = models.DateField(default=default_event_date) category = models.ForeignKey(Category) users = models.ManyToManyField(User, related_name='events', limit_choices_to={'is_staff': True}) ... How can I get a queryset from this model and organize the data so that I can display it (in a template) something like this: Date1 Date2 Date3 Date4 ... User1 CatA (Title1) CatC (Title4) CatB (Title7) - User2 CatD (Title2) CatB (Title5 - CatD (Title9) User3 CatC (Title3) CatC (Title4) CatC (Title8) CatC (Title10) User4 - - - - User5 - CatA (Title6) - CatD (Title9) ... Where DateN is the date field, UserN is the users field, and CatX is the category field, and TitleN is the title. -
Django, JS/JQuery validate inputs and disable submit button

Celery inspect queries hang forever
I have a dockerized celery implementation with redis as broker. Currently I only run one worker instance for celery. To monitor celery, I also added flower docker service but I am unable to monitor as the request times out. Upon looking into things I found that my celery inspect queries are simply non responding. They hang forever. Now, I think there is an underlying issue with my celery-redis setup. I am unable to inspect anything, when I try to add a task for background processing they are getting stuck upon the calling statement itself. Its all behaving weird. Versions: celery 4.0.2 redis 5.0.0 Currently, I am unable to debug in any capacity. Any help is gladly appreciated. -

Development vs. Production Media Location in Django
I'm working on user-uploaded files with Django. I often this this in various articles: urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^file/', include('file_app.urls')), ] if settings.DEBUG: urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) Which implies that if DEBUG is on and you're developing, then add the MEDIA_URL path to urlpatterns so it's accessible. So what is the appropriate way to store files in a production environment and why isn't this method suitable in production? -
Python requests POST don't contain all sended data
I'm trying to create new order on PayU, via their REST api. I'm sending "get access token", and i have correct answer. Then i send 'create new order', aaaaand i ve got 103 error, error syntax. I was trying on https://webhook.site/ , and realized why syntax is bad - i have no values in list. Code of sending POST, when creating new order: data = { "notifyUrl": "https://your.eshop.com/notify", "customerIp": "127.0.0.1", "merchantPosId": "00000", "description": "RTV market", "currencyCode": "PLN", "totalAmount": "15000", "products": [{ "name": "Wireless mouse", "unitPrice": "15000", "quantity": "1"}]} headers = { "Content-Type": "application/json", "Authorization": str('Bearer ' + access_token).encode()} r = requests.post('https://webhook.site/9046f3b6-87c4-4be3-8544-8a3454412a55', data=payload, headers=headers) return JsonResponse(r.json()) Webhooc show what i have posted: customerIp=127.0.0.1&notifyUrl=https%3A%2F%2Fyour.eshop.com%2Fnotify&currencyCode=PLN&products=name&products=unitPrice&products=quantity&description=RTV+market&merchantPosId=00000&totalAmount=15000 There is no values of 'name', 'unitprice' and 'quantity'. PayU confirmed thats the only problem. Why? What is wrong? Sending simple POST request to get a token is always successful. -

How do I create a filter with AngularJS to show/hide certain items?
I am trying to create a filter to show and hide certain items in my list. I already have two filters set but I can't seem to get this one working. As you can see I had some help with the others but this help is no longer with me. I am running AngularJS. So far, I have the following: 1) To show and hide prices. <h4 class="pl_header">Hidden Prices</h4> <ul class="price_list_filter"> <li> <label> <span>Show</span> <input type="checkbox" class="faChkSqr pull-right" ng-model="filter_hi" value="Hi" ng-change="hidden_show()"> </label> </li> 2)Added it into my body. <tbody ng-repeat="price_level in price_levels | orderBy:propertyName:reverse | filter:filterByCategory | filter:filterByType | filter:searchSKU | filter:filterByHide" ng-style="{ 'background-color' : (price_level.buyer) ? 'lightgray' : 'white' }"> 3) My javascript. $scope.hidden_show = function() { $scope.UIfilterby.hide = []; if($scope.filter_hi == false){ $scope.UIfilterby.hide.push("Hi"); } $scope.UIfilterby.hide = $scope.UIfilterby.hide.join(); } and $scope.filterByHide = function(price_level){ if($scope.UIfilterby.hide){ return ($scope.UIfilterby.hide.indexOf(price_level.hidden) !== false); }else{ return {}; } } I followed similar structures to the other two filters, one was filter by category and the other as by type. Maybe I need to add it to my filters.py in django? I am new to this, any help would be appreciated. Thank you. -
