social auth django: disconnect vs disconnect_individual
So I have added the disconnection pipeline to my application using python-social-auth. I noticed that there are two endpoints in the urls.py: disconnect - /oauth/disconnect/<backend>/ disconnect_individual - oauth/disconnect/<backend>/<association_id>/ Where backend could refer to the social provider (facebook, google-plus, linkedin, ...). Through my experiments, I find that the first endpoint, disconnect, will remove the logged in user's associated UserSocialAuth table entry. What does the second endpoint do? What does the association_id represent? Is it a way of dissociating one individual account if the user has two UserSocialAuth entries with the same backend? That doesn't make sense since the uid + provider must be unique. Can someone provide an example of when one would call the disconnect_individual? -
django model for subsite wagtail multisite
I am creating a wagtail instance which includes actually 4 sites: a portal-site and three nearly identical subsites. The subsites contain in the footer a django-form, and within this django-form I want to include a number of date-objects that are specific for the subsite. To clarify the setup: there will be a subsite for kids-training, youth-training and adults-training. The form needs to include the next three training-dates (DateTime) for the target-group, and these dates need to be created by the site-owner. I have not yet found a way to create a non-page model (django-model) that can be added to a subsite. Snippets seem not the way to go, and Site Settings does not seem to cover this usecase. Any solution-suggestion would be welcome. -
Just django dynamic formset and ajax
I use django dynamic formset and ajax to chekc the inventory. When I add a form, how to have ajax pick up change on the new form? dynamic formset adding forms $('#form-inline tbody tr').formset({ addText: 'add link', deleteText: 'remove', prefix: 'ptpositions' }); I loop the form in ajax but I don't think this is a good way. $(document).ready(function(){ {% for forms in formset %} $(".{{forms.stock.value}}").change( function(){ var symbol = $(".{{forms.stock.value}} option:selected").text(); {% endfor %} {% for forms in formset %} $.ajax({ url: "{% url 'inventory:get_position' ptinventory_obj.id date %}", type: "GET", data: { 'product': product }, datatype: 'json', success: function(data) { $(".{{forms.id.value}}_ouput").html(data.price); }}); {% endfor %} }); }) Now if I add form, then the ajax doesn't work. -
Visualization of xlsx files in a django project
I am willing to work on a project, in which I have a database (xlsx files), and I want to migrate it to a nosql database in order to visulize the data in plots, and then integrate it in a django website using plotly to make the graphs. My question is, is it better to migrate to a nosql database knowing that files will be added daily, or just use a sql one like postgresql? And which is better to do the job, mongoDB or Elasticsearch ? -
Trying to pass arguments from java script to python, and have python return back the result on my java script page
I am trying to test a simple function using java script and python.

Issues redirecting in Django
I'm deploying a django app, and I have two forms: One for rating and another for contact in the home page. Both of them redirect to the home page after save a model. The contact form works fine, but the rating form keeps the post url and doesn't save the model, and after doing it again, it save it. For example, I'm in www.site.com, then I send a post request from the rating form, the form redirect me to www.site.com/rating/ without saving the data. Then, if I'm send from www.site.com/rating/ the same form, the data is saved and redirect to www.site.com/rating/rating/ (404). The contact form works fine with the same process, and I think both are similar. The contact form redirects me to www.site.com like I want. I don't know why is this happening. urls.py urlpatterns = i18n_patterns( url(r'^admin/', admin.site.urls), url(r'^i18n/', include('django.conf.urls.i18n')), url(r'^', include('myapp.urls')), prefix_default_language=False ) myapp/urls.py urlpatterns = [ url(r'^contact/', views.contact, name='contact'), url(r'^rating/', views.raiting, name='rating'), url(r'^', views.index, name='home'), ] myapp/views.py def contact(request): if request.method != 'POST': raise Http404('acceding from GET') msg = ContactForm(request.POST) if not msg.is_valid(): context = { 'contact_errors': msg.errors } return render(request, 'home.html', context) msg.save() return redirect('home') def rating(request): if request.method != 'POST': raise Http404('acceding from GET') … -

Django CreateView autofill custom user
I want to use Django's GCBV CreateView to autofill the created_by field on my model with the current user.

Make jenkins indicate failure on failed tests

I can't figure out how to make the job indicator turn red and mark as a failure if the tests don't all pass. I'm not even sure what to Google to try to figure this out, so please forgive the apparent "lack of effort"... it's not the case. I'm just dead-ended at the start. -

How to best include field from Django ManyToManyField custom intermediary model when using prefetch_related?

Here is the queryset I have so far: User.objects.prefetch_related(Prefetch('teams', queryset=Team.objects.annotate(position=F('teammember__position')))) But it is doing an unnecessary join: SELECT `appname_user`.`id` FROM `appname_user` LIMIT 21; args=() SELECT (`appname_teammember`.`user_id`) AS `_prefetch_related_val_user_id`, `appname_team`.`id`, `appname_teammember`.`position` AS `position` FROM `appname_team` LEFT OUTER JOIN `appname_teammember` ON (`appname_team`.`id` = `appname_teammember`.`team_id`) INNER JOIN `appname_teammember` T3 ON (`appname_team`.`id` = T3.`team_id`) WHERE T3.`user_id` IN (1); args=(1,) It is joining appname_teammember twice when it doesn't need to.

Django REST framework rendering a field (or not) based on context
I've a Car class class Car(serializers.ModelSerializer): engine = EngineSerializer(many=False, required=False) owner = UserSerializer(many=False, required=False) and now I want to hide engine for users except the owner (this should be checked at self.context['user'] == self.owner. I can accomplish this by making engine into a SerializerMethodField() class Car(serializers.ModelSerializer): engine = serializers.SerializerMethodField() owner = UserSerializer(many=False, required=False) def get_engine(self, obj): if self.context['user'] == self.owner: return EngineSerializer(self.engine, many=False).data else: return None or so but this would create problems when creating + updating. What is the best practice for this? I don't aim privacy but just want to avoid cost of serializing the engine (imagine it takes a long time to serialize and it's useless for people except the owner) -

AJAX post request slow every second time [Django]
As a little side-project I created a Django-based Web Application. So far I have created my webpage with basic Javascript. I can successfully get data from the database and create an AJAX POST-request via Javascript. Everything is working BUT there is something that really bothers me: Every second POST-request takes a significantly longer time to reach the server. For example: Request1 returns successful after 29ms. Request2 needs (for the exact same task!) over 300ms. This goes on and is 100% replicable. I have no idea what the reason for that issue is. I hope someone can guess what the root for this problem is. Image of "request-waterfall" from the developer tool. Used Code: //THIS IS THE POST REQUEST IN THE JS-SCRIPT (CLIENT-SIDE) $.ajax({ type: "POST", url: '/update_database', data: { "habit_name": habits[h].habit_name, "meta_data": meta_data }, success: function(result) { update(); console.log('Successful'); } }); Server-side handling of the POST-request: def update_database(request): post_dict = dict(six.iterlists(request.POST)) habit_name = post_dict["habit_name"][0] meta_data = post_dict["meta_data"][0] change_meta_data(habit_name, meta_data) data = { "Habits": Habit.objects.all().values() } return JsonResponse(list(data["Habits"]), safe=False) -

Django: Creating categories using querysets/filtering
I'm trying to figure out if it's possible to create categories using custom filters. I am building an e-commerce app and I have set up my category model using mptt. I am importing a csv that creates my top level categories which works fine. The problem is I will need to have sub-categories that are more specific e.g Men's Clothing(Top Level) > Jeans. The csv has several fields that contains info relating to each product e.g description: "stone wash bootcut jeans".
