Showing ManyToManyField in Django Admin Site
I'm going through the Mozilla's django tutorial. They're basically creating a public library. They do not really talk about ManyToMany relationships, and have set it up so that one book can only have one author. While going through this tutorial, I decided to instead of copying their local library, to go ahead and try to create the basic functionality of IMDB. So that I do not end up just basically copying and pasting the code and not learning anything. I have set it up in a way that a show can have many creators using the ManyToMany field. In my class Creator I have two variables first_name and last_name. I have another class Show that has a bunch of other variables. Now inside my admin.py of the app called show, I want it so that in my ShowAdmin, it will display the creators in the admin table. The problem lies in the fact that Django does not support ManyToMany because it's a huge load to query. Now my possible solution is to: 1) create an empty array 2) loop through the first_name array and add it to the empty array. 3) loop through the last_array and add it to the … -
Django: how to access JsonResponse dictionary in jquery?
Jquery $('#id_buysell').on('change', function(){ console.log("buysell"); var $id_buysell = $('#id_buysell').val(); console.log($id_buysell); $.ajax({ method: "GET", url: "/myportfolio/add_transaction", data: { buysell: $id_buysell } }); }); Views def add_transaction(request): if request.method == "GET": if request.is_ajax(): print("ajax test") #print(request.GET.get) print(request.GET.get('coin')) print(request.GET.get('buysell')) data = { 'view_buysell': request.GET.get('buysell'), 'view_coin': request.GET.get('coin') } form = TransactionForm(user = request.user, coin_price = GetCoin("Bitcoin").price) return JsonResponse(data) How do I access that dictionary sent from JsonResponse(data) in views to my jquery file? I have a limited understanding of jquery and front end development in general. I know that this will be sent through a JSON-encoded response, but have not been able to find the right answer when searching. -
Resources to put a web application online?
I'm a trainee developer, who is making his first steps in web development. I don't understnd how to put something online, once I have built an entire web application. I'm currently mounting a web server and I'd like to understand what I'm doing. I'm building a blog with django. I'm setting the URLs, the IP address, and the database. I'm following the Djangogirls tutorial. Any resource where I can learn more about what I'm doing? I'm just following the tutorial mechanically and I don't like it. Any book or online course? Something in Udemy? How did YOU learn about it? Thank you! -
setting gaffer + Profile with Django on VPS

Nginx proxy pass with django's APPEND_SLASH
Django has the APPEND_SLASH setting which transforms urls like x/y into x/y/ and returns 301 Moved Permanently redirecting to x/y/. nginx is set to proxy_pass requests like myserver.com/myapp/url to myserver.com:myport/url, django is listening on myport. What happens is: nginx receives a request to myapp/x/y, rewrites the url and proxy_pass-es x/y to django, django returns 301 redirecting to x/y/ which results in 404 on myserver.com/x/y/ because the myapp part of the url is lost. I don't want to hardcode myapp in django in any way because it's a part of nginx config. I tried proxy_set_header Host myserver.com/myapp in nginx and a middleware before CommodMiddleware in django to manage redirects, but myserver.com/myapp is not a valid domain name and django throws an exception. How can I setup nginx + django so that redirects from django go to the correct url while django knows nothing about nginx config? -

Django - Creating a link that maps to multiple different pages?
I'm new to coding and I'm trying to create a link using Django (if possible) that sends the user to three different urls with equal probability of being to redirected to each one. Thus there is only one button to select but it can have three different results. I would like the link to simply be a bootstrap nav bar button. So far I have the following code that works just fine for a single basic html (surprise.html) url that I created: Relevant code in: Views: def surprise(request): return render(request, 'sitepages/surprise.html') Templates: <a class="nav-item nav-link" href="{% url 'surprise' %}">Surprise</a> urls.py: url(r'^surprise/', sitepages.views.surprise, name="surprise"), So this will redirect to a basic internal html page. But I was wondering if it's possible to add another href to the template code? Perhaps a new model would be necessary? I was thinking of using random.choice with three different urls in the list but it seems they need to be in str type and this is beyond me. Any suggestions or tips would be greatly appreciated. Thank You! -

Nuxt app cannot access one REST API, but all others work
I have a web app with a Django backend and a NuxtJS front end running in docker. The backend uses REST framework JWT Auth to control access. My URLs file looks like this: urlpatterns = [ path('api/auth/login/', obtain_jwt_token), path('api/auth/verify/', verify_jwt_token), # other urls here ] These two methods work perfectly from postman when the docker container is running - I'm able to obtain and verify JWT tokens as expected. However, when the front end calls these methods the login method still works perfectly, but the verify method fails. There are a number of other methods in my app that also work fine when called from the front end. Here is the error i get: Error: connect ECONNREFUSED 127.0.0.1:8000 I find this really weird, as normally this message would imply some sort of CORS issue, but as the other methods work, I don't see how it can be the case here. Here's how I'm calling the login/verify APIs from my front end (in my store.js file). Whenever the user refreshes the page, nuxtServerInit retrieves the token from the browser cookie and attempts to call the verify method to get the user profile in the front end export const actions = { … -
Types and sub types in Django Models
This seems to be fairly simple but the solution doesn't feel intuitive enough to me. Could not find an SO post with this exact question though. I have a School model with a ManyToMany mapping to an Area model which then has a OneToMany mapping to a SubArea model. class School(models.Model): area = models.ManyToManyField(Area, blank=True) sub_area = models.ManyToManyField(Area, blank=True) class Area(models.Model): name = models.CharField(max_length=100, unique=True) class SubArea(models.Model): name = models.CharField(max_length=100, unique=True) area = models.ForeignKey(Area, blank=True) A School object can belong to one or more Areas and a specific SubArea within an Area but doesn't feel quite intuitive to put sub_area in the School model because I feel that it should somehow be coming 'through' the area field, though I could be wrong. Is the above an ideal way to model this? -
