Timing issue with image upload on Heroku + Django Rest Framework + s3
ok this is a mix of architecture design and code question.. I've had this problem on a couple of applications and I'm not sure how to handle this. The problem is fairly basic, an app which allows users to attach files/images to an object. Let's say I have the following Django models: Document and Attachment. class Document(models.Model): body = models.TextField(blank=True, help_text='Plain text.') class Attachment(models.Model): document = models.ForeignKey(Document, on_delete=models.CASCADE, related_name='attachments') attachment = models.FileField(upload_to=get_attachment_path, max_length=255, null=False) filesize = models.IntegerField(default=0) filetype = models.CharField(blank=True, max_length=100) orientation = models.IntegerField(default=0) The get_attachment_path callable simply builds a path based on the document pk and the user. When a user creates a document, he can attach files to it. As it's a modern world, you want to be able to upload the files before creating the document, so I have a TempUpload object and a direct connection from the web application to S3 (using pre-signed URL). When the user clicks save on the document form, I get an array of all the TempUpload objects that I need to attach to the new document. Now here's the problem... within the heroku 30s timeout constraint, I need to: create the document (quite fast) iterate the array of TempUpload objects, and … -
HTML pages loading problems and buffer
Hi have a project that use Django/Python to create a web app, my problem is that on some page that rely heavely on Jquery Dialog and forms it takes up to 20 seconds to load the page. When the page load, it does like a buffer and for a few seconds display everything on the page on top of each other (like jquery tabs and dialog poping on top of the page) so i wanted to add a loading buffer and hide everything until the page is load. i just added divs in the body <div class="loader"></div> <div id="body" style="display:none;"> and this in the document.ready $('#body').show(); But my problem is that the page buffer for a few seconds, display nothing (not even the loader) then the loader pop for not even 3 seconds and the page end up fully loaded. What i don't understand is that if my page take so long to load why isn't the loading buffer image staying during the whole loading phase ? -

Django force redirect to home page
this is easiest to explain with an example. I have an HTML button, when it is clicked it is supposed to change a status-field in the database. After the status-field is changed, the user is supposed to be redirected back to home. Below is the HTML-button that calls a Javascript function: {% for group in groups %} <button id="approve-btn" onclick="approvePendingGroup({{ group.pk }})">Approve</button> {% endfor %} Here is the Javascript-function: function approvePendingGroup(id) { window.location.href = "/result/approve/" + id; } The Javascript-function calls the following URL, which calls a method in views. urlpatterns = [ url(r'^result/approve/(?P<pk>\d+)/$', views.approve_group, name ='approve_group'), ] Here is the views-method that is supposed to redirect back to home: @csrf_exempt def approve_group(request, pk): group = Group.objects.get(pk=pk) group.status = Status.approved group.save() return reverse('home') Unfortunately, this does not lead to the http://127.0.0.1:8000/home page It takes me to the: http://127.0.0.1:8000/result/approve/1/home page instead. It just appends "home" to the previous URL. How can I force this method to redirect directly to home, and not just append it at the end of http://127.0.0.1:8000/result/approve/1/? Thank you for your time! -
Django class based view and template with some div section
I have my Django class based view in which in the get method I am rendering a template with 4 div section(when one div section is being displayed, other three are hided, just for information). Each div section in the template displays a different set of data from a model. The logic of the extraction of data that I want to display is mixed and code is such a mess. Now my code is like this: class MyClass(View): def post(...): .... def get(self, request): # about 50 lines of code in which I am extracting data from models # but is too messy ... # in context I put extracted data context={'proposte_richieste': proposte_richieste, 'proposte_richiedibili': proposte_richiedibili, 'offerte_richiedibili': offerte_richiedibili, 'offerte_richieste': offerte_richieste, 'richiesteapprovate': richiesteapprovate, 'richiesteOapprovate': richiesteOapprovate, 'studente': studente, } return render(request,'myapp/mytemplate',context) I want something like this: class MyClass(View): def post(...): .... def get(self, request): def functionForDiv1(): ...#code for extract data for div1 def functionForDiv2(): ...#code for extract data for div2 -

Django not listening on port when execute runserver remotely (python - paramiko)
I have several Django applications on a Ubuntu computer (not in a production environment). When I connect via putty (ssh) from my Windows computer to that Ubuntu computer and start the applications with: 'python ./manage.py runserver x.x.x.x:yyyy'. I can connect to x.x.x.x:yyyy/app from every other computer in our network. So far, so good. For my co-workers however, I want to make a script so that they can start/stop the applications without using putty. I'm trying to do that with Python and the paramiko lib. I have these lines in my script: ssh = paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect(ubuntu.server, username=ubuntu.uname, password=ubuntu.pwd) ssh_stdin, ssh_stdout, ssh_stderr = ssh.exec_command("nohup python {0}/manage.py runserver {1}:{2} &".format(subpad, ubuntu.server, port)) When the script is executed I can see the Django server is running in the 'ps -aux' output, but I cannot connect to the app(s) from my browser. Also when I run 'netstat -vatn' I cannot see the Ubuntu computer listening to the specified port(s) (while the Ubuntu PC is listening to these port(s) when starting the servers via putty). Why is this? And how can I solve this problem? -

Slow distance query in GeoDjango with PostGIS
I am using GeoDjango with Postgres 10 and PostGIS. I have two models as follows: class Postcode(models.Model): name = models.CharField(max_length=8, unique=True) location = models.PointField(geography=True) class Transaction(models.Model): transaction_id = models.CharField(max_length=60) price = models.IntegerField() date_of_transfer = models.DateField() postcode = models.ForeignKey(Postcode, on_delete=models.CASCADE) property_type = models.CharField(max_length=1,blank=True) street = models.CharField(blank=True, max_length=200) class Meta: indexes = [models.Index(fields=['-date_of_transfer',]), models.Index(fields=['price',]), ] Given a particular postcode, I would like to find the nearest transactions within a specified distance. To do this, I am using the following code: transactions = Transaction.objects.filter(price__gte=min_price) \ .filter(postcode__location__distance_lte=(pc.location,D(mi=distance))) \ .annotate(distance=Distance('postcode__location',pc.location)).order_by('distance')[0:25] The query runs slowly taking about 20 - 60 seconds (depending on filter criteria) on a Windows PC i5 2500k with 16GB RAM. If I order by date_of_transfer then it runs in <1 second for larger distances (over 1 mile) but is still slow for small distances (e.g. 45 seconds for a distance of 0.1m). So far I have tried: * changing the location field from Geometry to Geography * using dwithin instead of distance_lte Neither of these had more than a marginal impact on the speed of the query. The SQL generated by GeoDjango for the current version is: SELECT "postcodes_transaction"."id", "postcodes_transaction"."transaction_id", "postcodes_transaction"."price", "postcodes_transaction"."date_of_transfer", "postcodes_transaction"."postcode_id", "postcodes_transaction"."street", ST_Distance("postcodes_postcode"."location", ST_GeogFromWKB('\x0101000020e6100000c425c79dd2c1ccbf17a06d35ebc44940'::bytea)) AS "distance" FROM "postcodes_transaction" INNER JOIN … -

Ajax not firing after I added a GeoJson 'data'
I have an HTML page where a button click will fire an ajax function showDetail(): <a href="#" class="list-group-item" onclick="showDetail({{ test.id }});"> <strong>{{ test.test_name }}</strong></a> The ajax function works well if it's like this on its own: function showDetail(id){ $.ajax({ url : "/test/" + id, type: 'GET', success: function(data){ map.removeLayer(tests); $('#pane-content-edit').html(data); $('.tests_display').animate({right:0}); } }); } I would like to modify it having the current HTML page containing a Geojson. And I'd like to pass it to my ajax to pass it to the url my ajax is pointing at. So I did this: function showDetail(id){ $.ajax({ url : "/test/" + id, type: 'GET', data: {'tests_geojson' : {{ tests_geojson | safe}}}, success: function(data){ map.removeLayer(tests); $('#pane-content-edit').html(data); $('.tests_display').animate({right:0}); } }); } After adding that, it would not fire. I tried opening up the web console, nothing is happening. Can someone help? or tell me how to debug this? Thank you!

Moving an current DJango app to a different sub-directory
I have an app that was created in an "old" directory using "django-admin startproject businesscontacts" old location: C:\Users..\backendworkproj\businesscontacts moved to new location: C:\Users..\backendworkproj\appmasterdata\businesscontacts Now, of course, the app that was working is now broken. My understanding is that "C:\Users..\backendworkproj\appmasterdata" needs to be put in the PYTHONPATH. I know that there are other explanations out there - but - I am trying to follow one of the responses listed here: Permanently add a directory to PYTHONPATH It says: Instead of manipulating PYTHONPATH you can also create a path configuration file. First find out in which directory Python searches for this information: To me, it is not clear exactly what is to go into the .pth file. I did not see anything stating whether or not a full-path is needed or a realtive-path or ... In my case, 1. run python -m site --user-site output => C:\Users\...\AppData\Roaming\Python\Python36\site-packages 2. Made sure that the directory existed 3. echo "$HOME/foo/bar" > "$SITEDIR/somelib.pth" Again, not sure what is supposed to be in the .pth file - or - what the name of the file should be (with Step #3) TIA -
The current path, didn't match any of these. error django
Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/votes/ Using the URLconf defined in votes.urls, Django tried these URL patterns, in this order: ^$ [name='index'] The current path, votes/, didn't match any of these. You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page. this is my urls.py of my app. from django.conf.urls import url from . import views urlpatterns = [ url(r'^$', views.index, name='index'), ] this is my urls of my entire project from django.conf.urls import include, url from django.contrib import admin urlpatterns = [ url(r'^votes/', include('votes.urls')), url(r'^admin/', admin.site.urls), ] I tried to approach to admin site but i couldn't. how can I fix it?
