How to I find all the attributes of request.session.get

Django Url Pattern Not Being Found
I followed a tutorial to allow users to register an account but the url path does not seem to be found. It allows me to access 127.0.0.1:8000/accounts/signup but not 127.0.0.1:8000/signup when I have set the name for it. I tried changing the urlpatterns from a path to a url method but that didn't solve the problem. my file structure is as follows: App: accounts: urls.py views.py ... Server: settings.py urls.py ... templates: registration: login.html base.html home.html signup.html manage.py In my Server\urls.py I have from django.contrib import admin from django.urls import path, include from django.views.generic.base import TemplateView urlpatterns = [ path('admin/', admin.site.urls), path('accounts/', include('accounts.urls')), path('accounts/', include('django.contrib.auth.urls')), path('', TemplateView.as_view(template_name='home.html'), name='home'), ] In my accounts\urls.py I have from django.urls import path from . import views urlpatterns = [ path('signup/', views.SignUp.as_view(), name='signup'), ] The error I get is Using the URLconf defined in Server.urls, Django tried these URL patterns, in this order: admin/ accounts/ accounts/ [name='home'] The current path, signup, didn't match any of these. I'm not too sure what is going on since I'm still sort of new to Django and busy learning as I go along. -

How to setup nginx for multiple website under one domain?
I created two websites (with database) using django, let's call them web1 (database=web1_db) and web2 (database=web2_db). I'd like to run them under one domain in this way (main.html for example, each website has url.py to direct pages): www.mywebsite.com/web1/main.html www.mywebsite.com/web2/main.html I'm using nginx and uwsgi to serve the website and I can get web1 and web2 work separately. To serve both websites as stated above, I setup uwsgi in emperor mode (successfully, I think), but I can't figure out how I should config nginx to make this work. Can someone give me some suggestion? my nginx conf for single website is as below: upstream mywebsite { server unix:///tmp/mywebsite.sock; } server { listen 80; server_name www.mywebsite.com; proxy_http_version 1.1; ssl_protocols TLSv1.2; location /media{ alias /pathtomedia; } location /static{ alias /pathtostatic; } location / { include /etc/nginx/uwsgi_params; include /etc/nginx/mime.types; uwsgi_pass mywebsite; } } -

Set the data in render method after pre-declaration in Django
I have declared the variable as given below: response = render( request, 'authme/login.html', {} ) At some point of time, I need to set the temporary cookie and pass the value of temporary cookie in the view. I tried the following ways to set the data as given below: response['message'] = "Login Failed: Please try again" response.message = "Login Failed: Please try again" Can anyone suggest how can I set the message part using variable "response", in the same way, How do we use for setting cookie, PFB: response.set_cookie('message','Login Failed: Please try again') So that it is equivalent to this line of statement: response = render( request, 'authme/login.html', {"message":"Login Failed: Please try again"}) -
How to let users define the Django model complying with their excel files to upload?
I am starting to develop a django project which need to provide a HTML page for other students to upload their experiment results which are excel files (maybe CSV), and save them to databases. But when it comes to defining the models, most tutorial define the "static" model rather than letting users to define them. In my case, students may have diffent sheets to upload, for someone it maybe "date-time, id, max, min, eta", while "date, time, name, sex, notes" for someone else. Currently I can get the first row of the xls files and use them as the headers of database, and import them with excuting a single *.py file. But how can I do this with Django and deal with the database? Can anyone help me? Django 2.1.7 -
Codes in one of my views are not processed when I access to that view
My intention is to change from interface view -> switch view to process some data and send those data and change to -> test view to display the result. However, nothing in switch view seems to be processed and switch view doesn't change to test view after I hit 'submit' on userInterface.html. My guess is that the problem lies on the HttpResponseRedirect() function or anything related to url paths. Everything worked find with my other project that I worked on my computer. I'm not sure what I need to change to use Django on RaspberryPi. At first, I found out I didn't import libraries needed for those function. After I imported them, the code was still not working. I commented out other codes in switch view that do nothing with changing views and just focus on changing view in my switch view. view.py def user_interface(request): return render(request,'zuumcoin/userInterface.html', {}) def switch(request): return HttpResponseRedirect(reverse('zuumcoin:test')) def test(request): return render(request,'zuumcoin/test.html',{}) userInterface.html .... <form action="{% url 'zuumcoin:swicht' %} method = "POST"> {% csrf_token %} ... ... </form> urls.py app_name='zuumcoin' urlpatterns = [ url(r'', views.user_interface, name='interface'), url(r'switch/', views.switch, name='switch'), url(r'test/', views.test, name='test') ] I expect HttpResponseRedirect to direct me to test view instead of being stuck … -

How can I structure my JSON response using the Django Rest Framework serializer?

Unable to correctly parse URLs using Django template language
I currently am trying to link a researcher's name if they provided a link, otherwise if they provide a blank input or N/A, then I choose not to link their name. I use the information from the researcher object using Django's template language, but when I check the result it ends up linking all of them, and those without input just have href = "" which links back to the homepage. I've tried using {{r.website_link|length}} instead, but that just creates errors and the page won't load. I'm a newbie to frontend so I'm not sure if my "if" statement is incorrect or if my HTML logic is incorrect. <div> {% for r in researcher %} <div class="researcher"> {% if "{{r.website_link}}" != "N/A" and "{{r.website_link}}" != "" %} <p><a class="researcherwebname" href="{{ r.website_link }}">{{ r.fullname|title}}</a> | {{ r.institution }} | {{r.position}} | <i>{{ r.des|capfirst }}</i></p> {% else %} <p> {{ r.fullname|title}} | {{ r.institution }} | {{r.position}} | <i>{{ r.des|capfirst }}</i></p> {% endif %} </div> {% endfor %} </div> I expect it to link researchers with an actual r.website_link input, otherwise the name should be unlinked.
