Javascript function doesn't wait until the end of promises
I have got a function that invokes when a button is clicked, and I am trying to fetch data through API upon clicking. and below is the function that gets triggered onclick. I have to fetch data through API once and then based on a field from the fetched data, I need to fetch another data from another data table. so, I have designed my coding as below, and my console looks like this: And the console looks like this: All done []length: 0__proto__: Array(0) 1466 (customer_id logged during for loop) 1663 (customer_id logged during for loop) I thought based on the promise logic, all done should have been read in the end, am I missing anything here? so Ideally, Alldone console should have invoked at the end containing data fetched based on customer_ids 1466, 1663. I am not sure what I am missing, I am new to javascript as well as stack overflow, so detailed answer would be so much appreciated. function test(pmt_id, crm_supplier_id) { const url = 'http://127.0.0.1:8000/creditor-detail/'+pmt_id+'/supplier/'+crm_supplier_id+'/' let promises = []; const results = fetch(url) .then(resp => resp.json()) .then(function (item) { var list = item; for (var i in list) { promises.push(getCustomer(list[i].customer_id)); console.log(list[i].customer_id) } }) Promise.all(promises) .then((results) … -

Can't access self.request.user when overriding FilterSet.qs
I have written code for a filter that takes into account some fields of a given patient (name, age and id). The users of the website will be doctors, and I want only patients of the current logged in doctor to come up in the search. After reading the docs and trying to do so in many different ways, I have accomplished nothing. It seems the best method is to override the FilterSet.qs function and so I did, similarly to what is present in the documentation. However, when I try to access self.request.user it comes back as none, even though there is a user currently logged in. I am new to Django and still trying to figure things out. Any help is highly appreciated. I believe I have pasted in all that is relevant, but I am sorry in advance if something is missing. # filters.py import django_filters from .models import Patient, Teams from django import forms from django.contrib.auth.models import User class PatientFilter(django_filters.FilterSet): id = django_filters.NumberFilter(widget=forms.NumberInput(attrs={ 'min': '1'})) age = django_filters.NumberFilter(widget=forms.NumberInput(attrs={ 'min': '0'})) class Meta: model = Patient fields = { 'first_name' : ['icontains'], 'age' : ['exact'], 'id' : ['exact'] } @property def qs(self): parent = super().qs author = getattr(self.request, … -

Linking Different List Views of 2 models together who share the same User
I am trying to add a Post to a list view, the class DesignerPostListView(ListView) has already an Item context. In my project, a user can add a post and add an item each is a different app with different models. So In my DesignerPostListView(ListView), I have my items related to a specific user looped. What I am trying to do is check if this item.user has a post existing related to the user and if it does exist a button show appears in the page linking to another page with these posts related to the very same user. There is another list view called class UserPostListView(ListView): with the same idea looping posts filtered to a specific user. In order words if there are no posts related to the user the button should not appear but if there is 1 or more the button should appear. I have tried to add a condition to the template but it is not working correctly and I think there might be another easier way to do it through the views. here is the item models.py class Item(models.Model): designer = models.ForeignKey( User, on_delete=models.CASCADE) title = models.CharField(max_length=100) here is the designer list views.py class DesignerPostListView(ListView): model … -

Heroku: Django Migration release not running in deployment
I have a Django application running in Heroku. On the initial deployment, I manually migrated the database schema using heroku run. The next time I needed to push migrations to the app, the release went off without a complaint. However, when I went to the page to see it live, I was returned a programming error: the new column didn't exist. The migrations had never been run. Here's my Procfile: web: gunicorn APP_NAME.wsgi --log-file - release: python manage.py migrate release: python manage.py collectstatic --noinput worker: celery worker -A APP_NAME -B -E -l info The collectstatic release is run successfully, but the migrate release is seemingly ignored or overlooked. When I manually migrated, they migrated without error. There is an empty __init__.py file in the migrations folder. If anyone knows what could possibly be hindering the migrate release from running, that would be awesome. -

How to wait for a promise to resolve before the next iteration in for loop
I have got two data tables I want to query some data from, so the way i thought about doing it is fetch url and based on a field from list, I do fetch(url) once more to get related data from another data table and I want to append them together to display on the browser.

I am using django_restframework, and it is me trying to fetch data by passing criteria(variables) through urls. can anyone help? var url = 'http://127.0.0.1:8000/creditor-detail/'+pmt_id+'/supplier/'+crm_spplier_id+'/' var results = fetch(url) .then((resp) => resp.json()) .then(function(item){ var list = item for (var i in list){ getCustomer(list[i].customer_id) .then(function test(user) { return user[0].customer_name }); var spmt = ` <tr id="data-row-${i}"> <td>${list[i].po_no}</td> <td>${list[i].amount}</td> <td>${I want return value[user[0].customer_name]}</td> </tr> ` wrapper.innerHTML+= spmt } }) function getCustomer(customer_id){ var url = 'http://127.0.0.1:8000/user-detail/'+customer_id+'/' var results = fetch(url) .then((resp) => resp.json()) .then(function(item){ return item }) return results } -
Create local files with python in Django
I want to create files with the extension .txt, .csv, .bin, etc. so the ideal would be with import os I think or if there is some other better way. But I don't want to save those in the DB they are to consult the once or sporadically, that is, locally are uploaded to the server and then it is replaced and that's it. In a simple way, I create the files I need, upload them and replace them when I need something that will not be so common. The directory for these local files would be /app/files/. -

Hitcount Not Counting No. of Visits for A Detail View
I have followed https://github.com/thornomad/django-hitcount to implement Django Hitcount but I might be missing something I am not sure what it is as the count is 0 and remained like this even if I refreshed and even changed users. I think there might be some problem in the views just before the context where there is an arrow Here is the models.py @python_2_unicode_compatible class Post(models.Model): designer = models.ForeignKey(User, on_delete=models.CASCADE) title = models.CharField(max_length=100, unique=True) hit_count_generic = GenericRelation(HitCount, object_id_field='object_pk', related_query_name='hit_count_generic_relation') Here is the views.py class PostDetailView(HitCountDetailView, DetailView): model = Post template_name = "post_detail.html" def get_context_data(self, *args, **kwargs): context = super(PostDetailView, self).get_context_data() post = get_object_or_404(Post, slug=self.kwargs['slug']) comments = Comment.objects.filter( post=post, reply=None).order_by('-id') total_likes = post.total_likes() liked = False if post.likes.filter(id=self.request.user.id).exists(): liked = True if self.request.method == 'POST': comment_form = CommentForm(self.request.POST or None) if comment_form.is_valid(): content = self.request.POST.get('content') reply_id = self.request.POST.get('comment_id') comment_qs = None if reply_id: comment_qs = Comment.objects.get(id=reply_id) comment = Comment.objects.create( post=post, user=self.request.user, content=content, reply=comment_qs) comment.save() return HttpResponseRedirect("post_detail.html") else: comment_form = CommentForm() context.update({ 'popular_posts': Post.objects.order_by('-hit_count_generic__hits')[:3], <----- I think error from here }) context["total_likes"] = total_likes context["liked"] = liked context["comments"] = comments context["comment_form"] = comment_form return context here is the urls.py app_name = 'score' urlpatterns = [ path('', PostListView.as_view(), name='score'), path('details/<slug:slug>/', PostDetailView.as_view(), name='post-detail'), path('hitcount/', include(('hitcount.urls', 'hitcount'), …
