Having trouble serving image from django rest API using angular
I am currently having an issue rendering an image from my newly created products API using Django REST Framework. I have everything else loading but the images will not load. I am using angular to consume the API data with the following code: myStore.controller("myStoreController",function($scope,$http){ $scope.gems = $http.get("/api/products/").then( function(response){ $scope.gems = response.data }, function(error){ $scope.error = error }); }) Here is the product rest URL code: from django.conf.urls import url,include from rest_framework import routers from products_rest.viewsets import ProductsViewsets router = routers.DefaultRouter() router.register('products',ProductsViewsets,'products') from django.conf.urls.static import static from django.conf import settings urlpatterns = [ url(r'^', include(router.urls)) #base router ] + static(settings.MEDIA_URL,document_root = settings.MEDIA_ROOT) Lastly, here is the main settings URL for the django app: from django.conf.urls import url,include from django.contrib import admin from django.conf.urls.static import static from django.conf import settings urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^api/', include('customerreview_rest.urls', namespace='api')), url(r'^api/',include ('products_rest.urls', namespace='api')), url(r'^', include('GemStore_App.urls',namespace='frontend')), ] + static(settings.MEDIA_URL,document_root = settings.MEDIA_ROOT) When I navigate to the URL of the image, I can access the image, but for whatever reason I can't get the image to display to the page. And the API looks like this currently: [ { "name": "Dodecahedron", "price": 30, "description": "Some gems have hidden qualities beyond their lustre, beyond their shine. This … -
How to create a field in MySQL that get data from the callable function in Django?
How can I set a django field that gets data from a function depending on other fields? Let me explain using the following example. class Test(models.Model): def testType(self): return str(self.__class__.__name__) sources = models.CharField(default= testType, max_length=50, null=True, blank=True) In this case, if I go to django front-end interface and hit "add Test", I can see a box for 'sources' to fill out. This is not the way I wanted. I want: 1. a field named 'sources' in the back-end MySQL database, 2. No box for 'sources' to fill out in the "add Test" form, and 3. The 'sources' field will get data as soon as we add a new record. Any suggestion that can help me to solve this issue would be appreciated. -
Django Form transport

Customizing Django Sitemap Index
I have created a sitemap index in Django that links to three other sitemaps.

Nginx cache static files from different aplications
I use WordPress as a home page (mysite.com) and Django for the rest (mysite.com/pages). I have single nginx config file for both of them and its working fine. Moreover, they reside in a single server block. Here are some parts of my configuration: server { ... root /var/www/wordpress; ... location /static/ { alias /home/username/Env/virtenv/mysite/static/; } } With this both WordPress and Django static files are served. Now I want to cache all static files for 7 days in the browser. If I put this in addition: location ~* \.(jpg|jpeg|png|svg|gif|ico|css|js)$ { expires 7d; } then the WordPress static files are properly cached, but Django's static files are not even served. I know this is because the /static/ location is never reached and then Nginx searched Django's files in the root directive which is on server block level and which points to the WordPress location. I can remove the cache location and add expires 7d; in the /static/ location. This will in opposite cache only the static files of Django. But how can I make both static resources to be cached for a week? -

Django: How to make an API call just before browser tab close?
I am using Django v1.10 for an application where in need to send an API call just before browser close through crude javascript (don't want to use any library for sake) preferably. I've read about window.unload and window.onbeforeunload. The first one didn't seem to work at all. The second can work but it also gets executed when there is reload or redirection to another page (it works as it should but that is what I don't want). I've tried using SESSION_EXPIRE_AT_BROWSER_CLOSE of Django which works only when a user has totally exit out of the browser (no browser process running). I've also seen answers on the web where people have suggested to open another window/tab of the browser through JS as the tab closes. So in precise words, I want to make an API call just before browser tab close (not in any other situation). Please help! -

Python 3.5 - Django 1.8 - after login {{ next }}
I am currently learning Django by reading a popular book for this framework called "Django by example". Currently, I am at the 4th chapter and even though I can managed to follow the instructions, I did not fully understand something.

How to use Django to run python scripts?
Sorry for the super basic question. I have a simple python script with a function that takes string inputs, makes a list, and prints out the length of the list. I wanted to see if I could use Django to use this python script function as part of a website, where a webpage takes the input from a form, passes it to the python function, and then returns the output to the web page. Sounds simple enough. My question is this: Is Django meant for this? It seems most Django tutorials are about user admin stuff, templates, and database creation. I can't find an easy to understand solution to what I want to do even after having gone through the Django documentation poll tutorial and several other tutorials. Is this something that should be written in JavaScript if I want to actually carry out what my python script function does? -

Starting multiple processes in Celery
I have a problem with configuring Celery for Django. This is how I start django-celery: python manage.py celery worker --autoscale=10,2 Example of a task: @task def test(i): print "ITERATION {} START".format(i) time.sleep(10) print "ITERATION {} END".format(i) return True And I call this task with: for i in range(10): test.delay(i) What I expect to happen is that if I send 10 tasks to queue, 10 processes should open - one for each task. What actually happens is that the random number of processes are started, usually 4 and after these 4 tasks are finished, another 3 start and after they finish, another 3 start. This happens even for tasks that take longer to complete, e.g. 2 minutes. Can someone explain this behavior? How can I start all tasks immediately if autoscale upper limit allows it? Also, though lower limit in autoscale is 2, when server is started, 3 processes run. Why is that? Platform: OpenWRT, Dual-Core processor, 2GB RAM. -
