Maintaining active tab in Django
I'm working on an application that has three tabs, one of which I would like to have marked as active at all times. Based on a similar question, I currently have the following in my base template: <div class="tab"> <a class="{% if request.resolver_match.url_name == 'home' %}active{% endif %}" href="/">Home</a> <a class="{% if request.resolver_match.url_name == 'questions' %}active{% endif %}" href="/questionManager/">Question Manger</a> <a class="{% if request.resolver_match.url_name == 'course' %}active{% endif %}" href="/courseManager/">Course Manager</a> </div> Which works great when navigating between /, /questionManager/, and /courseManager/, respectively. The issue is that if I navigate to another page (for example, /questionManager/addQuestion/), the tab is no longer marked as active. Is there a way that I can maintain the active state no matter where I want to navigate? Specifically, the 'question' tab should be marked active for all /questionManager/*, the 'course' tab should be marked active for all /courseManager/*, and the 'home' tab should be marked active for everything else. I realize I could pass along some variable indicating whether it's question/course/home in the context whenever I'm rendering a response, but that seems like a lot of repetition and I feel like there's an easier way to do what I want to do. -

Basic Django Search Implementation
I am having some difficulty retrieving the user submitted data from the form. I am able to hard code a 'term' and successfully search the database, but with the current code I have now, I receive a MultiValueDictKeyError when the results are dynamically populated. So, I am wondering what approach I should use to handle the line: "term = request.GET['term']". views.py def search(self, request): try: r = requests.get( self.URL + 'company/contacts?childConditions=communicationItems/value=' + request, headers=self.Header) r.raise_for_status() except: print(r.text) raise return r.json() def search_bar(request): term = request.GET['term'] results = objCW.search(term) context = {'results': results} return render(request, 'uccx/search.html', context) urls.py urlpatterns = [ path('', views.table_content, name='table_content'), path('search_form', views.search_bar, name='search_bar')] search.html <html> <head> <meta charset="utf-8"> <title>SEARCH</title> </head> <body> <form action="" method="get"> <input type="text" name="term"> <input type="submit" value='Search'> </form> {% if results %} Found the following items: <table class="table"> <thead> <tr> <th>First Name</th> <th>Last Name</th> <th>Company</th> <th>E-Mail</th> </tr> </thead> <tbody> {% for result in results %} <tr> <td> {{ result.id }}</td> <td>{{ result.lastName }}</td> <td> {{ result.company.name }}</td> <td> {{ result.communicationItems.0.value }}</td> </tr> {% endfor %} {% endif %} </tbody> </table> </body> </html> -

Html table rendering
my Django view is returning a list of dictionaries. This goes to html table through template rendering. Below is my template code, My list of dictionary looks like below, Results : [{ 'name' :'x','age': 20}, {'name': 'y','age': 25 }] <table class="table table-striped" border="1" class="dataframe"> <thead> <tr style="text-align: center;"> {% for k, v in results.0.items %} <th>{{ k }}</th> {% endfor %} </tr> </thead> <tbody> {% for x in results %} <tr style="text-align: center;"> {% for y in x %} <td> {{ x.y }} </td> {% endfor %} </tr> {% endfor %} </tbody> </table> Expected output: name age x 20 y 25 But output is blank . Please let me know is there anything wrong with my html table template. -
Django rest framework , serializer - after submitting with POST method will not lead back to homepage
i am a django newbie here. I am confused as in why after i have submitted a POST request, the django rest framework will lead me to this page here instead of bringing me back to my homepage this is my views.py: class TableData(APIView): def post(self,request,*args,**kwargs): startRange = request.POST.get('mcap') endRange = int(startRange) + 29868 sector = request.POST['cat'] print(str(sector)) stocks = StockInfo.objects.filter(Q(company__company_categories__contains=sector),Q(companymcap__range=(startRange,endRange)),Q(datetimecollect__contains=datetime.date(2018,3,13))) serializer = TableSerializer(stocks,many=True) return Response(serializer.data) my serializers.py: class TableSerializer(serializers.ModelSerializer): #stocks = serializers.StringRelatedField(many=True) company_name = serializers.CharField(source='company.company_name') company_id = serializers.IntegerField(source='company.company_id') company_categories = serializers.CharField(source='company.company_categories') class Meta: model = StockInfo fields = ('company_name', 'company_id', 'company_categories','companyprice', 'companyvolume', 'companyeps', 'companydps', 'companynta', 'companype', 'companydy', 'companyroe', 'companyptbv', 'companymcap') My initial idea is that after a person has chosen some criteria from my html form then when they submit the form, I will query the database based on their criteria and load it into a serializer. Then using the serializer to fill up my ajax data table in my html page. I tried my best and i still do not know what is wrong... -

Django vs Angular for a simple page to show results of a Python program
I'm working on a school project on Machine Learning where I implemented a Python program using Tensorflow, and now I have a set of results (predictions) in the form of CSV/JSON that I want to display to the user. I've decided to make a not too complex web page (only home page, no user's profile, admin page, etc) to show my results. After reading about Django I thought it would integrate niceley with the Python program and I managed to create a website, but I'm starting to realize that maybe Django would be too back-end focused: I'm heavily using the template side, mainly a lot of Javascript (jQuery and Chartjs), and only using the controller side to pass the JSON results to the template. I've never worked on Angular, but I read it's more client side front-end based, so it might be a better option for the interface I want to create. So what would be the simplest way to create the web app? Should I continue using Django and Javascripts libraries, even though I'm virtually not exploiting any of the back-end features, or should I go with Angular? -
Django Rest Swagger 2.2.0 Api's on TokenAuthentication not being shown
Currently, I'm using DRF 3.7.7 and Django-rest-swagger 2.1.2, in the following fashion. settings.py SWAGGER_SETTINGS = { 'SECURITY_DEFINITIONS': { 'api_key': { 'type': 'apiKey', 'in': 'header', 'name': 'Authorization' } }, # 'LOGIN_URL': getattr(settings, 'LOGIN_URL', None), # 'LOGOUT_URL': getattr(settings, 'LOGOUT_URL', None), 'DOC_EXPANSION': None, 'APIS_SORTER': None, 'OPERATIONS_SORTER': None, 'JSON_EDITOR': False, 'SHOW_REQUEST_HEADERS': False, 'SUPPORTED_SUBMIT_METHODS': [ 'get', 'post', 'put', 'delete', 'patch' ], 'VALIDATOR_URL': '', } views.py from rest_framework.schemas import AutoSchema class RandomClass(APIView): authentication_classes = (TokenAuthentication, ) permission_classes = (IsAuthenticated, ) schema = AutoSchema( manual_fields=[ coreapi.Field( "page_id", required=True, location="query", type="string", description="Facebook Page ID" ) ] ) This allows me to somewhat use drf-schema to render each view individually in swagger docs. The caveat is that, since this view enforces Authentication, only after I authorize an user (authorization by token, as per swagger settings security definitions) I can view all my IsAuthenticated views. Also, If a single view function has multiple methods (get and post) the schema generation for both is same (if I do it this way. I have two problems here. I want to know what would be the proper way to move forward for APIView using TokenAuthentication (I didn't get any useful docs whatsoever and had to scrape forums for a working solution).

Is there a way to regenerate PO files from weblate with new formatting?
In an attempt to reduce the frequency of merge conflicts and unhelpfully large diffs in weblate generated PO files I have opted to use the "no wrap" formatting option of the "Customize gettext output" addon on an existing project. This seems to work fine however the nowrap formatting is only applied to strings that are modified. Is there a way I force weblate to regenerate all strings in the PO files even if the string is unchanged (thereby applying nowrap to every translation string in the project/component)? https://docs.weblate.org/en/latest/admin/addons.html#customize-gettext-output -

Django instance crashes after a while when running on elastic beanstalk
im running a django project with elastic beanstalk. I'm using Python 3.6 running on 64bit Amazon Linux/2.7.0. Already earlier had a problem with mod_wsgi and had to follow https://serverfault.com/questions/884469/mod-wsgi-call-to-site-addsitedir-failed-on-aws-elastic-beanstalk-python-3 to avoid daily crashes. Now my eb instance is crashing in a weird way after a random amount of time (usually couple hours). The logs provided below show a weird /RPC2 POST that starts a flood of csrf errors and end with a SIGTERM. After the crash the server tries to restart but with disregard of env vars like DJANGO_SETTINGS_MODULE. The variable is set in 01_packages.config and I can see it set properly in the aws console. Any ideas what could cause this?
