Django: Generating form & passing data
I spend my Sunday on this, but I am still not where I need it to be. What I want to do: Ticketing shop, with ticket data received from the ticket model. The visitor can choose the quantity of different kind of tickets and is then being passed to the checkout form. The challenge: I can't just create a simple form, as the form is depended on ticket model. Therefore I have to combine the ticket model data with a selection for quantity. What's next (after clicking on "Checkout"): I will save this data in a checkout model with a unique cart_id and an entry model with ticket_id, quantity and cart_id(foreign key). The checkout view will then get the ticket data from the ticket model and the quantity from the entry model. Through that, I can calculate total amount etc. Where I need your help: I have problems with creating the form. In know how to save data in the database, but I don't get the data into formset.is_valid() I hope you can help me solving this. Thank you in advance. models.py from django.db import models # Create your models here. class Ticket(models.Model): description = models.TextField() name = models.CharField(max_length=120) price_gross … -
Django Setting up a test from a populated database?

Django React Axios
I am trying to make a post request to a Django server using React with Axios. However, I am getting a redirect 302 on the server side. Just followed all suggestions in this post here CSRF with Django, React+Redux using Axios unsuccessfully :( However, what I have done so far is the following: Sat the default axios CookieName and HeaderName (on the javascript side): axios.defaults.xsrfHeaderName = "X-CSRFToken"; axios.defaults.xsrfCookieName = "XCSRF-Token"; Got this in settings.py as well: CSRF_COOKIE_NAME = "XCSRF-Token" And here is how the post request looks like: axios( { method: 'post', url: `/api/${selectedEntryType}_entry`, data: { "test": "test" }, headers: { 'X-CSRFToken': document.cookie.split('=')[1], 'X-Requested-With': 'XMLHttpRequest', 'Content-Type': 'application/json', } } ) Another thing that I have tried is to make the post request from the Django rest api UI: and it does work successfully. The only differences in the Request Headers when I make the request from the UI and from JS are: Accept, Content-Length, and Referer, which I don't see how could they be problematic. Please help. -
Django's password_reset keeps returning error
I'm trying to use Django's built in password_reset view, and so far I followed a small tutorial, but in my case, and as I found out, also many other people's, it doesn't work, and everytime I access the specific url, it returns: "Reverse for 'reset_password' not found. 'reset_password' is not a valid view function or pattern name.". I looked for all kinds of solutions, but the only one that actually worked was to move the urls with password_reset and password_reset_confirm to the main urls.py, instead of the one in my subdirectory. Still, if I access the url "raw", aka just typing it instead of rendering the page through link and all, it does indeed work, but If I try to access it through some actual link, it returns the very same error I got from the start. In my main/urls.py : url(r'^reset_password/$', password_reset, name='password_reset'), url(r'^reset_password/done/$', password_reset_done, name='password_reset_done'), ^This one doesn't work in any way, it just returns that error. I checked for possible typos or bad declaration, but it is alright. Like I said, if I take these two urls and put them in urls.py instead of main/urls.py, it does work. But then I tried to implement a link in … -
Loop to render Django view context as table in the template
I want to pass the following dictionary as context to Django template: context = {'prices': prices, 'listings_links': listings_links, 'listings_names': listings_names, 'photo_links': photo_links} The dictionary's values are lists. In the template I want to display those lists as columns in HTML table.

How can I write a method only used POST or GET?
I wanna divide the program in the case of POST and GET.I am using wide use view in urls.py from django.urls import path from . import views urlpatterns = [ path('top/', views.TopViews.as_view({ 'get': 'getdata', 'post': 'postdata' })), ] in views.py class TopViews(viewsets.ModelViewSet): #what should I write here?

Switching between templates displayed in Django
I'm beginning to work on a Django application. I'd like to have two different views which switch dynamically when the user clicks on one of the tabs on the screen. Here is essentially what I have: base.html: <head> <script type="text/javascript" src="/static/base.js"></script> </head> <body> <div class="tab"> <button class="tablinks" onclick="changeTab(event, 'teams')">Teams</button> <button class="tablinks" onclick="changeTab(event, 'scenarios')">Scenarios</button> </div> <div class="content container"> <div class="tab-options"> <div class="teams-tab" id="teams-tab"> {% block teams %} {% endblock %} </div> <div class="scenarios-tab" id="scenarios-tab"> {% block scenarios %} {% endblock %} </div> </div> </div> </body> teams.html: {% extends "./base.html" %} {% block teams %} <body> <form action="{% url 'webapp:results' %}" method="get"> <h1>You are on the teams page!</h1> <input type="submit" name="submit" value="Get Results!"><br> </form> </body> {% endblock %} index.html: {% extends "./base.html" %} {% block scenarios %} <body> <form action="{% url 'webapp:results' %}" method="get"> <h1>You are on the scenarios page!</h1> <input type="submit" name="submit" value="Get Results!"><br> </form> </body> {% endblock %} base.js: function changeTab(event, tab) { tabcontent = document.getElementsByClassName("tab-options"); for (i = 0; i < tabcontent.length; i++) { tabcontent[i].style.display = "none"; } if (tab == "teams") { document.getElementById("teams-tab").style.display = "block" } else if (tab == "scenarios") { document.getElementById("scenarios-tab").style.display = "block" } } Unfortunately, this doesn't seem to be working.

In Django, how to save queried object with datetime attribute?
I'm able to save other attributes of a queried object but not time. Am I missing something with q.edited_datetime = timezone.now()? q = SomeObject.object.get(id=3) q.title = 'New Title' q.edited_datetime = timezone.now() q.save() In models: edited_datetime = models.DateTimeField(blank=True, null=True, default=None) That's basically the code I'm using. timezone.now() works if I create the object. -
Updating Django static files to Pythonanywhere seemed to work, but website not showing (Djangogirls Tutorial)
I am very new with Django, PythonAnywhere and coding in general. But I tried to make the question as clear as possible. Here is my problem: I'm trying to learn Django, and I got stuck with one of the final steps of this tutorial: https://tutorial.djangogirls.org/en/extend_your_application/ From the part where it says "Updating the static files to the server" (Scroll down in the link) Everything works fine on my localhost, but it doesn't work on PythonAnywhere. The website is not showing. I've searched on stackoverflow (and on the web) for similar questions, but either the questions/answers are so sophisticated that I can't follow them, or the solutions point to things that I think are already in place, and aren't the solution to my problem.

Django schedule - rely on database or google
So i´m working on a project for university. Basically what i do is writing a website where one can add entries to a calendar which are stored in a google calendar. Therefore the website calender needs access to google to read entries and write new ones. At first the idea was to use google so theres no need to care about where/ how to store data. Now that i started working on it i noticed that django has a lot of calendar modules so now i´m wondering wether there are any pros and cons to using google as a "storage" or storing it myself? I will use google calendar either way because my tutor want the syncronisation between web calendar and google calendar. Thanks for your help =) -

Django forms - hyphens instead of underscores in names of IDs
In HTML, the best practice is to use hyphens instead of underscores in names of ids.For example, this post refers to this issue. However, Django for some reason uses underscores when automatically generating ids from the names of the model fields. Is it possible to override this behaviour somehow ?
