How to deploy bootstrap theme "QuixLab" in django?

Updating the axis of a highcharts chart object using jquery after inital render (django)
I can seem to figure out a basic question I’ve got a highcharts chart in my django app that is getting loaded in the template. The data for the chart is getting populated via ajax. I’d like to add a button above the chart which if clicked toggles the axis to logarithmic (instead of the default, linear) but I can’t seem to make this work Here’s my code HTML <button id="target" type='button' > switch to log </button> <div id="container1" style="width:100%; height:400px;"></div> Javascript <script> $(document).ready(function() { var chartOptions = { chart: { renderTo: 'container1', type: 'line', }, title: {text: null}, xAxis: {title: {text: null}, labels: {rotation: -45}}, yAxis: {title: {text: 'Item counts'}, type: 'linear', stackLabels: {enabled: true}, }, plotOptions: {column: {dataLabels: {enabled: false}, stacking: 'normal'}}, series: [{}], }; var chartDataUrl = "{% url 'global_trend_chart' %}" ; $.getJSON(chartDataUrl, function(data) { chartOptions.xAxis.categories = data['chart_data']['date']; chartOptions.series[0].name = 'Global counts'; chartOptions.series[0].data = data['chart_data']['item_counts']; var chartA = new Highcharts.Chart(chartOptions); }); $( "#target" ).click(function() { chartA.update({ yAxis: { type: 'logarithmic', } }); }); } ); </script> I appreciate the help -

How do I redirect away from the login page, if the user is already logged in and goes to login page in Django?
I'm using built in authentication system of Django 2.1. Example Case: User logs in by providing his credentials, once he is directed to the home page and presses browser's back button he'll land in the login page again. It'll again ask for the credentials but actually the user is already logged in. How do we redirect the user to the home page in this case? -

Django - Images aren't loading in second app

Django merging between two querysets by adding an element from one queryset to the other every nth element
Assume I have in my model "movies" of several types: E.g.: Action, Drama, Fantasy etc... In my template I would like to list the 50 most recent movies (sorted by date). Which is rather straight forward E.g.: Movies.order_by('-date')[0:50] However, I have an additional requirement: I would like to list Action movies (sorted by date) every 3 movies of other types: E.g.: (0) Drama 12/3 (1) Adventure 11/3 (2) Science 10/3 **(3) Action 11/3** (4) Sci-Fi 9/3 (5) Sci-Fi 8/3 (6) Adventure 4/3 **(7) Action 8/3** (8) Drama . . . (50) ... In other words, merge two query sets: movies sorted by date of all movies excluding action movies. movies sorted by date of only actions movies. The new query set (or list?) should be 3 items from the first query set and 1 item from the other query set. -

How to access ForeignKey child model's ID? int() argument must be a string, a bytes-like object or a number, not 'builtin_function_or_method

Django overwrite header value in request object
I am writing middleware that, when it receives a request containing a header 'foo', modifies its value, before passing the request on. Django makes direct assignment illegal, so these do not work: request.headers['Foo'] = 'bar' request['Foo'] = 'bar' I do have a working solution, but it's a bit hacky: request.headers.__dict__['_store']['foo']=('Foo','bar') Is there a cleaner way of doing it that I've missed? -
Keep a list of users who accessed specific url in model
What I'm trying to do is every time a user visits a URL related to the object, a viewed_by field gets updated with that specific user's ID number. I've had a look at this documentation but I feel like it doesn't really fit exactly what I need. I'm not sure about the implementation, which is why I'm asking this question, but this is how I'd imagine it or something like this. class Documents(models.Model): document = models.FileField(upload_to=my_upload) document_name = models.CharField(max_length=100) document_viewed_by = ??? #ids of each user that viewed the document -
annotate with RawSQL by entry
Is it possible to get the query of the RawSQL to work with one entry at a time? I'll give an example of my problem: I have a DateRangeField in a model (it's a Postgres field) date = DateRangeField(null=True) What I'm aiming to get is the days inside the range. I tried doing the next Django ORM query models.my_model.objects.annotate(diff_days=RawSQL("""SELECT UPPER(date)-LOWER(date) FROM my_model_db_name""",[])) Which of course led to the following error (because the query FROM is the whole table) django.db.utils.ProgrammingError: more than one row returned by a subquery used as an expression and that's because RawSQL is expecting a single result (e.g. put SUM or COUNT in the SELECT expression) and that's because of the query executed by the entire table instead of the current object. Is there a way to implement it into Django ORM? The other solution is, of course, to get the executed result and then calculate it by raw. -

In django rest framework, How to get queryset of foreignkey instead of url?
In models: class Brand(models.Model): name = models.CharField() class Product(models.Model): price= models.CharField() brand = models.ForeignKey(Brand) In serializers, I use hyperlink and in views, I use viewset and also in urls I use routers. As output in API, in Product url i get the Product queryset and the value of brand is a url link. But i want the queryset of Brand in Product queryset. How can it possible? For frontend I use axios, when i get a request in Product queryset here I also get url for Brand because of foreignkey. I need to access the queryset of Brand when I send get request for Product url. How can I do that? -

NoReserveMatch and Error during template rendering
i am new at this thing. first, this is my urls.py urlpatterns = [ path('results/<int:id>/', views.abstract, name='abstract'), path('results/', views.result, name='result'), path('', views.index, name='index'), ] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) and my wiews def index(request): return render(request, 'online_sp/index.html') def result(request): script = Main() data = script.json_dt if 'No result' in data.keys(): no_result = True return render(request , 'online_sp/scripts.html', {'no_result':no_result}) else: return render(request , 'online_sp/scripts.html', data) def abstract(request, id): return render(request , 'online_sp/abstract.html') my goal is get page results/1/ with a button click from results/' page.
