Django rest framework social auth
I'm trying to implement the django-rest-framework-social-oauth2 library, following the linked instructions to set up LinkedIn (in place of Facebook). I've added the app, as it says in the instructions, but I don't understand what to do with the redirect URI, as the instructions state that it should be blank. I have a link on my website of the form: https://www.linkedin.com/oauth/v2/authorization?response_type=code&client_id=CLIEND_ID&redirect_uri= http%3A%2F%2Ffoo.com%2Ffrontend%2Flogin_redirect&scope=r_basicprofile When I click this, linkedin confirms the request and then redirects to the link encoded in the url above (http://foo.com/frontend/login_redirect) with some parameters in the url. I should then send those parameters to a particular linkedin api endpoint to obtain a token for the user. Currently, when linkedin tries to redirect, a 404 error is returned. I tried adding that redirect URI to the redirect URIs of the application, and the result was the same. To summarise, do I need to use a particular redirect url (in which case, what is it?), or, if not, how do I tell django-rest-framework-social-oauth2 which redirect URI it should make available? -
Is it possible to migrate data from MySQL to PostgreSQL through Django dumpdata?
I'm trying to convert my database from MySQL to PostgreSQL, and I'm using AWS RDS. I was trying AWS DMS to migrate data, however it didn't work well and was complicated. While struggling with that, an idea came to mind. What if I use migrate migrations to the new PostgreSQL, and dumpdata from MySQL and loaddata to PostgreSQL? Would that work? Does anyone have experience to migrate database? Am I approaching a right direction? -

Django Priority Queue
I want to build a delivery app in Django, wherein I will create delivery objects to be delivered according to priority(attribute of the object) by a delivery person. I will login and create the tasks and there can be many delivery persons to login and accept task asynchronously. Objects(tasks) will be popped out as a delivery person logs in and accepts the task, and the next logged in delivery person would see the next priority task. How can this be implemented in Django? Any references and implementation links are welcomed. Thanks in advance! -
Which pattern to use to add functionality to dango models
I have several models in my Django project. Most of these models are quite simple, but some of they are the entry point to complex data structures. For example, Reservation model has several detail models through foreign key relationships (ReservationHotel, ReservationTransfer, ReservationTour, ReservationRountrip, ReservationService), and each one of these details has foreign relationship with product models (Hotel, Transfer, Tour, Roundtrip, Services). I know a good practice is to keep models isolated from other models, so they must not know the detail about them. Due to this, I implement controllers to manage complex data structures like the one described before. I want these controller to implement design patterns, and I believe the proper one for Reservations should be the Proxy pattern, based in its description in wikipedia: What problems can the Proxy design pattern solve? The access to an object should be controlled . Additional functionality should be provided when accessing an object. When accessing sensitive objects, for example, it should be possible to check that clients have the needed access rights. What solution does the Proxy design pattern describe? Define a separate Proxy object that can be used as substitute for another object (Subject) and implements additional functionality to control … -
Django REST: How to overwrite field type of a serializer class
I am trying to overwrite serializer's data field, which is a CharField,like this: from jsonfield import JSONField class ActivitySerializer(serializers.ModelSerializer): data = JSONField() class Meta: model = Activity fields = ("date_added", "start_date", "data", "number", "athlete") But when I try to print the representation of the serializer -print(repr(my_serializer)) - the type of field data remains unchanged: ActivitySerializer(<Activity: START DATE: 2018-11-19 06:08:49+00:00, ID: 1973222369, DATE ADDED: 2018-11-20 18:07:32.818798+00:00>): date_added = DateTimeField(read_only=True) start_date = DateTimeField(required=False) data = CharField(style={'base_template': 'textarea.html'}) number = IntegerField(required=False) athlete = PrimaryKeyRelatedField(queryset=Athlete.objects.all(), required=False) What am I doing wrong? -
Unique=True in Django model gives IntergretyError instead of ValidationError
I want to show a validation message like "This email is already in use" inside my html form. But I think i'm missing something. I keep getting an IntegrityError at my email field. Isn't Django supposed to validate this and give an ValidationError if I use unique=True in my model? Or do I have to Try and Catch the IntegrityError myself? Or maybe show me a best practice for validating unique users inside a form/model. models.py class Customer(models.Model): FirstName = models.CharField(max_length=50) LastName = models.CharField(max_length=50) Email = models.CharField(max_length=50, unique=True, error_messages={'unique':"This email is already in use"}) views.py def customerform(request): if request.method == 'POST': form = CustomerForm(request.POST) if form.is_valid(): post = Customer() post.FirstName = form.cleaned_data['FirstName'] post.LastName = form.cleaned_data['LastName'] post.Email = form.cleaned_data['Email'] post.save() return render(request, 'results.html', { 'FirstName': form.cleaned_data['FirstName'], 'Email': form.cleaned_data['Email'],}) else: form = CustomerForm() return render(request, 'form.html', {'form':form}) forms.py class CustomerForm(forms.Form): FirstName = forms.CharField (label='First name:', max_length=50) LastName = forms.CharField (label='Last name:', max_length=50) Email = forms.EmailField(label='Email:', max_length=50) form.html <form action="/customer/" method="post"> {% csrf_token %} {{ form }} <input type="submit" value="Submit"> </form> -

Django dumpdata returns empty array when models are in a version subdirectory
I have a Django Rest Framework app where I have separated my models/serializers/views into separate directories (instead of in models.py, serializers.py, etc) and moved those directories into a v1 directory. When I try to run ./manage.py dumpdata api I get an empty array as response. ./manage.py dumpdata will dump out the Django system tables, but none of my model tables. Here's an example: - api/ -- __init__.py -- v1/ --- router.py --- __init__.py --- models/ ---- __init__.py ---- thingy.py --- serializers/ ---- __init__.py ---- thingy.py --- views/ ---- __init__.py ---- thingy.py - project/ -- urls.py -- settings.py -- wsgi.py -- __init__.py The __init__.py file inside each object directory (e.g. models) includes the class from each file: from .thingy import Thingy The router.py file inside api/ looks like this: from rest_framework import routers from . import views router = routers.DefaultRouter(trailing_slash=False) router.register(r'thingies', views.ThingyViewSet) api_urlpatterns = router.urls And urls.py inside project/ looks like this: from django.conf.urls import url, include from django.contrib import admin from django.urls import path from api.v1.router import api_urlpatterns as api_v1 urlpatterns = [ path('admin/', admin.site.urls), url(r'^api/v1/', include(api_v1)), url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework')) ] -
Django, JavaScript, Google Street View: Linking JavaScript 'Click' Event Listeners for Multiple Items to Django Product & Cart Model
I would like to implement in Django a Google Street View where I could use JavaScript event listeners - 'click' to determine if buttons (Add to Cart) in the Street View has been clicked, so that all the items clicked on in the Google Street View is added to a cart when it is clicked.[reference here][1] In a typical Django shopping website, the products is added via the Django admin into the models. Then at the Django templates, the products are run iteratively with a 'for' loop to show all available products. Similarly for the cart to show all added products. {% for product in products.object_list %} {% for cart_item in cart_items %} I plan to add all products into the Django models first. The problem is how can I link every button (Add to Cart) for each specific product item in Google Street View via JavaScript 'Click' event listeners to the Django models/views? Is there a short code example that can show this being done? Thank you! -
How can I add data to my model containing User as a foreign key from a custom-made form in django?
Here, when I try to add a new note with a user logged in, I want that note to have its user-field filled with the current logged in user. So I wrote user=request.user But error arises: UNIQUE constraint failed: mynotes_note.user_id Here are my files: models.py class Note(models.Model): user = models.ForeignKey(User,on_delete=models.CASCADE) title = models.CharField(max_length=50) desc = models.TextField() def __str__(self): return self.title addForm.py from django import forms class addForm(forms.Form): title = forms.CharField(max_length=50, widget=forms.TextInput(attrs={ 'class':'form-control' })) desc = forms.CharField(widget=forms.TextInput(attrs={ 'class':'form-control' })) Here, I used this way instead of using Meta class just to apply some bootstrap effects to the form fields views.py def addView(request): if request.user.is_active: if request.method=="POST": form=addForm(request.POST) if form.is_valid(): newNote = Note(user=request.user,title=request.POST['title'],desc=request.POST['desc']) newNote.save() return redirect('home') else: form=addForm() args={'form':form} return render(request,'mynotes/add.html',args) else: return redirect('home') -

Wagtail: Getting a list of snippets with counts of related parents
Using Wagtail I have ArticlePages, each of which can have 0 or more Authors, which are Snippets. I'd like to get a list of Authors with the number of ArticlePages they're attached to, but can't work out how. I'm getting confused by ModelCluster I think, as I'd be fine with vanilla Django.

How to add more than one django-leaflet map in a view?
I was able to show a map on a single page using django-leaflet. In another page, I am trying to show two (or more) maps in page but I couldn't figure out how. For showing map in a single page: <div class="card"> {% leaflet_map "main" callback="map_init" %} </div> <script type="text/javascript"> function map_init(map, options) { // get point lat and lon var lon = "{{ project.longitude }}"; var lat = "{{ project.latitude }}"; // zoom to point & add it to map map.setView([lat, lon], 12); L.marker([lat, lon]).addTo(map); }</script> Above works fine as long as one map needs to be shown. However I am not sure how I can modify above to support multiple maps. I have started jsfiddle page here (which is kind of blank), not sure if it's going to helpful.

Should I use JSONField over ForeignKey to store data?
I'm facing a dilemma, I'm creating a new product and I would not like to mess up the way I organize my datas in my database from the start. I have two choices to organize my models, the first one would be to use foreign keys to link my models together. Class Page(models.Model): data = JsonField() Class Image(models.Model): page = models.ForeignKey(Page) data = JsonField() Class Video(models.Model): page = models.ForeignKey(Page) data = JsonField() etc... The second one is to keep everything in Page: Class Page(models.Model): data = JsonField() # videos and pictures, etc... are stored here Is one better than the other and why? This would be a huge help on the way I would organize my databases in the futur. -
