Troubles making an user update view
I have a custom user model, subclass of AbstractBaseUser. I'm currently having troubles making an update view, so user could change his profile. Changing user through admin interface works fine. This is a form that I use to change user objects in both admin and app`s interface. class UserChangeForm(forms.ModelForm): password = ReadOnlyPasswordHashField( label=_("Password"), help_text=_( "Raw passwords are not stored, so there is no way to see this " "user's password, but you can change the password using " "<a href=\"{}\">this form</a>." ), ) class Meta: model = User fields = '__all__' def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) password = self.fields.get('password') if password: password.help_text = password.help_text.format('../password/') user_permissions = self.fields.get('user_permissions') if user_permissions: user_permissions.queryset = user_permissions.queryset.select_related('content_type') def clean_password(self): return self.initial["password"] I'm using fields = '__all__' to be able to change all the fields through admin interface. But in app's intreface I want user to change only some fields. This in my view: def update_user(request): form = UserChangeForm(request.POST or None, instance=request.user, fields=('email', 'first_name')) if request.method == 'POST': if form.is_valid(): form.save() return redirect('home') return render(request, 'update_user.html', {'form': form}) return render(request, 'update_user.html', {'form': form}) If I pass fields parameter like that UserChangeForm(request.POST or None, request.user, fields=('email', 'first_name')) I get __init__() got an unexpected keyword argument 'fields' … -

Django admin crashes when adding or editing object
I have a django model: class Foo(models.Model): user = models.OneToOneField(User, on_delete=models.PROTECT) def __str__(self): return self.user.username With the admin registered as a model admin. When I try to either edit an existing Foo object (which I first added directly to the DB with SQL) or click 'add' to create a new Foo object, the server crashes. Does this have something to do with the fact that the User table contains about 50,000 objects, and the server is running out of memory when it tries to load the Foo admin, because it OneToOne keys out to User? Is there a way around this? -

Can't render on base.html?
I have a base.html which essentially provides the navigation for my app. I want to be able to add some stats into the nav bar - so I am trying to render them onto base.html The same script works, if I change base.html to home.html, but I don't want to repeat the same code on every page, to retain the stats when I navigate away from home. Here is my view: def stats(request): incompletetasks = Todo.objects.filter(complete=False, creator=request.user).count() shared = Todo.objects.filter(Q(shareslotone=request.user) | Q(shareslottwo=request.user) | Q(shareslotthree=request.user) | Q(shareslotfour=request.user) | Q(shareslotfive=request.user)).count() closedtasks = Todo.objects.filter(complete=True, creator=request.user).count() context = {'incompletetasks':incompletetasks, 'shared':shared, 'closedtasks':closedtasks} return render(request, 'base.html', context) How can I make this render to base.html, rather than copying the same code for every page? Thanks -
How to tell Visual Studio Code to follow Django itself source code while debugging Django applications?
I have a Django application and I set Visual Studio Code to debug it using the default launch.json configuration. When I start the server (manage.py runserver) and make a request, VSCode stops at the first breakpoint (that is correct), but when I step into a function, VSCode never follows/shows Django source code itself and I would like to see what is happening inside that Django source code. How could I configure VSCode to follow/show Django (and Django REST) source code while debugging Django applications? -
Django noob - view Render/HttpResponse question
Django noob here. Some what comfortable with basics of models and some such. In short I have a Django project working on localhost properly producing a view that I need with (mind the messy code): def entry_list(request): editedbooks = EditedBook.objects.all() treaty = Treaty.objects.all() pilcases = PILCase.objects.all() journalarts = JournalArt.objects.all() return render(request, 'text/test.bib', {'treaty': treaty,'editedbooks': editedbooks,'pilcases': pilcases, 'journalarts': journalarts}, content_type='text/x-bibtex; charset=UTF-8') The view works for present purposes as I need it. In short I need to push a text file of the view to a publicly available repository such as git. I've read a little on HttpResponse and Content-Disposition but not sure how to modify the existing view function so that it functions as it does now but renders a bib (plain text) file.

Is there a way to integrate Django with Next.js?
I've integrated Reactjs with Django by having a function to access build/index.html. The below codes show how I do that. config/urls.py urlpatterns = [ ... re_path(r'search/', react_views.ReactAppView.as_view()), ] PROJECT_NAME/views.py class ReactAppView(View): def get(self, request): try: with open(os.path.join(str(settings.BASE_DIR), 'frontend', 'build', 'index.html')) as file: return HttpResponse(file.read()) except: return HttpResponse( """ Build your React app. """, status=501, ) ReactAppView function accesses index.html which is created with yarn build on React side. Basically, I used React just for search view, and other than search view, I used jQuery as it was developed with jQuery first. Since I found that I need Next.js to use Server Side Rendering (SSR) with React, I've been trying to migrate React app to Next.js. But, Next.js doesn't have index.html. It just has pages/index.js instead. I've tried very hard to figure out how to integrate Django with Next.js, but I can't find any helpful resource. Can anyone help me about this? -

Getting a count of objects the spans a relation

White-Space and Characters after white-space are not getting passed in GET request
Suppose I have a django model like this: class myModel(models.Model): names = models.Charfield(max_length=200) Values of objects stored in this model are 'Amanda','John Nash', 'Richard Benson' and 'Joe Williams' Now i have a html form which has a select element.I am fetching values to be put in option element from myModel using ajax function.Form is something like this: <form> <select multiple name='MyNames'> <option value='Amanda'>Amanda</option> <option value='John Nash'>John Nash</option> <option value='Richard Benson'>Richard Benson</option> <option value='Joe Williams'>Joe Williams</option> </select> <input type='submit' name='Save'> </form> If i select 'Amanda','John Nash' and 'Richard Benson' and click on 'Save' following is the GET request i am getting on my server. HTTP GET /testPage/?MyNames=Amanda&MyNames=John&MyNames=Richard&Save=Submit It is clear from the GET request that white-space and characters after white-space are not being picked up if values are fetched from the server. What could be the possible reason and possible solution for this. If i donot fetch values of options from server and rather put the values in option element manually, then this is not happening. Request in that case is like this. HTTP GET /testPage/?MyNames=Amanda&MyNames=John+Nash&MyNames=Richard+Benson&Save=Submit P.S:This is only a sample code.I have not given actual code for the sake of clarity as actual code is quite lengthy.Thanks in advance -

I am going to crawl the web with python and selenium. You attempted to crawl a loop with 500 operations to fetch 4 elements from a single line. The three elements will crawl without problems, but one element will stop with a 'no such element' error message during the loop. Below is the code I wrote. What's wrong? The page you want to crawl is a good access to the queryselector from Google Developer Tools. I will try for various days and try various things and ask for help. for i in range(0, review_page_count - 1): if i is not (review_page_count - 2): driver.find_element_by_xpath('//div[@id="south"]/div/nav/div/ul/li/a[contains(text(), "{}")]'.format(i+1)).click() time.sleep(5) if i > 0: driver.find_element_by_xpath( '//div[@row="{}"]/div[@colid="productName"]/a'.format(j)).send_keys(Keys.CONTROL + Keys.HOME) for j in range(0, 500): if j is not 0 and j % 4 is 0: driver.find_element_by_xpath( '//div[@row="{}"]/div[@colid="productNo"]/a'.format(j)).send_keys(Keys.PAGE_DOWN) product_num = driver.find_element_by_xpath('//div[@row="{}"]/div[@colid="productNo"]/a'.format(j)).text product_name = driver.find_element_by_xpath('//div[@row="{}"]/div[@colid="productName"]/a'.format(j)).text score = driver.find_element_by_xpath('//div[@row="{}"]/div[@colid="reviewScore"]'.format(j)).text review_content = driver.find_element_by_xpath('//div[@row="{}"]/div[@colid="reviewContent"]/a'.format(j)).get_attribute('text') review_date = driver.find_element_by_xpath('//div[@row="{}"]/div[@colid="createDate"]'.format(j)).text print(j) print(product_num, product_name, score, review_content, review_date) when get review_content row=126 caused ERROR plz help me! thx
