Django tag within URL tags
I would like to use dynamic images based on a a pk of the page. To be clearer I have a survey app, using one question per page .. which mean that the user is presented a question he answers and is redirected to the next question. Each question has a different id and I would like to attach to each question an image. Right now I have a static image lik that : <div class="col-5"> <img src="{% static 'images/RightSpeech.jpg' %}" class="img-fluid" alt="Responsive image"> </div> but I would like to make it dynamic.. I tried something like that with no success: <div class="col-5"> <img src="{% static 'images/image{{question.pk}}.jpg' %}" class="img-fluid" alt="Responsive image"> </div> any idea ? -
Django parallel are fialing if tests need to access files
I have a Django app that has many tests and it's taking a long time to finish testing, I'm thinking to run those tests on parallel, I tried but there is a problem with tests that need to access files, some tests are creating files and check if these files are created and exists in a path. For example, we have a test that will check-in a git repository and check if the git repository exists in the path. How to fix this issue? -
File lock in django
In my web application,created using django. I am reading a file from different instance and displaying the file with few editable text boxes. Once we edit it, when the save is clicked the file is written on the instance from where it is read. Now I have to lock the file once an user opens the file and edits it and tell other users to wait(but still they should be able to view the file only save cannot be done). I tried django-lock, simple Filelock. But did not get a clean example and got stuck. Note: There are no Models created. Users are created through the admin page. I read many docs where it is mentioned about models. If models are the only option how should i use it in my application. -
Django Connection Timed Out
I have installed a Django server on my home computer which is accessible from internet. The user can upload a file which is processed and than is redirected to another web page from where can download the result. The duration of input file handling can take between 30 secs to ~ 10 minutes depending of it's size. If I access the website from my home network, everything is working fine but when I access it from internet, I can only use small input files which can take up to max 30 seconds to process. If I wait for the result for more than 30 seconds, I get "Connection Timed Out" on my browser. Which would be the simplest solution to overcome this problem, either a timeout parameter config or making Django to send keep alive messages to user? Thank you -
Not getting parameters from openlayer 2 -request to django 1.11
I am using openlayers 2, Python2.7 & Django 1.11. For a search, I need to send a request with parameters from openlayers(javascript) to Django 1.11. I am able to submit the request but the parameters are not getting. My code is: Javascript: var params = '' var opnLyrRequest = new XMLHttpRequest(); params = 'pid=15&ctype=25&stype=50' opnLyrRequest.open('POST','/test/search/',true); opnLyrRequest.onreadystatechange=function(){ if(opnLyrRequest.readyState==4 && opnLyrRequest.status==200){ if(pinGeoJsonFrmt.read(opnLyrRequest.responseText)!=null){ dataLoc = pinGeoJsonFrmt.read(opnLyrRequest.responseText); if (dataLoc.length > 0) alert("Found !!"); else alert("No Data Found !!"); } } } opnLyrRequest.send(params); And the Django code working on the above request is: @csrf_exempt def searchSubmit(request): print request print request.method print request.POST print request.GET .... .... The getting output like this: <WSGIRequest: POST '/test/search/'> POST <QueryDict: {}> <QueryDict: {}> The parameters are missing !! -
bootstrap navbar dropdowns not showing with django
I'm trying to add twitter-bootstrap to a django project. I've got a html file called base.html which acts as a wrapper file for other html code which is placed inside of it before it gets send back in the HttpResponse. base.html {% load static %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <link href="{% static '/css/bootstrap.min.css' %}" rel="stylesheet"> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script> <script src = "{% static '/js/bootstrap.min.js' %}"></script> <title>TITLE</title> </head> <body> {% autoescape off %}{{ content }}{% endautoescape %} </body> </html> This file is the only file which will ever get send back to the visitor of the webside so I would imagine that if I add the files bootstrap needs inside base.html that it would work also on the code in content. Infact, all the css stuff seems to work fine but whenever I try to open a dropdown menu in the navbar of my site, it does not show up. This is the source code of the page that has difficulties: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <link href="/static/css/bootstrap.min.css" rel="stylesheet"> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script> <script src = "/static/js/bootstrap.min.js"></script> <title>TITLE</title> </head> <body> <nav class="navbar navbar-expand-lg navbar-light bg-light"> <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse … -
Fill a form field with initial values from another model (which is a foreign key)
I have 2 models, Company and Post. class Post(Meta): company = models.ForeignKey(Company, related_name='company', on_delete=models.CASCADE) company_description = models.TextField(max_length=800) What I need: 1) When a user create a post, the company FK will be set thru code 2) Also at form initialization the field company_description, will be prepopulated from the Company model, field description(not the same name) 3) On save if the user doesn't modify anything to the field, the initial value will be save 1,2,3 only on creation. I checked Django documentation regarding initialization but their example, is more simple they just get some data/text, in my case I first need to set FK, than get description from the FK Model, so not just text. -

Enforcing unique constraint based on foreign key
I enforced a unique constraint for a column and since the constraint is enforced on the entire table, is there a way to make a column unique based on the foreign key?

How can I let the superadmin user and user itself to access a API?
I have a UserUpdateAPIView, in it I can edit the user information: class UserUpdateAPIView(RetrieveUpdateAPIView): queryset = User.objects.filter(is_admin=False, is_staff=False, is_superuser=False).exclude(status=4) serializer_class = UserDetailSerializer lookup_field = "username" def perform_update(self, serializer): serializer.save() The UserDetailSerializer: class UserDetailSerializer(ModelSerializer): """ user detail """ class Meta: model = User exclude = [ 'password', ] depth = 1 Now, every user can access the UserUpdateAPIView, so its a bad design. I just want the super admin and the user itself can access the APIView, how to implement it? I know I can use permissions = [IsAdminUser] to allow the admin users to access this API, but I just want to let the super admin user and the user itself to access. -

Library, but also a project impacting another
In the moment, I have two github repositories, i.e. repo1 and repo2. Both are two django projects created by our team. In requirements.pipin ~/work_projects/repo1, I have the line -e git+ssh://git@gitlab.com/repo2.git@de5622dcf0b9a084f9b0a34cdd1d932026904370#egg=repo2 Hence, repo2 becomes a library used by repo1 in ~/.virtualenvs/venv/src (repo1's virtual environment). In the moment, I need to modify both repositories at the same time. My main focus in the moment is that each time I modify repo2, I need to test out the results on repo1. I want to look at the impact of repo2 on repo1 once modified. I don't want to push my changes on github and reinstall repo2 on repo1 each time I want to see those changes. How could I make it works easily, workaround? -

Django and Flask on same nginx server
