How can I display my comment form on the post detail page Django
So basically at the moment, if users want to add a comment to a post on my site, it takes them to another page with the form on it. However, I want the comment form to be on the actual Post Detail page, so users don't have to go to another page to comment. So far I have tried adding some context things and changed the url for the comment form's location to post_detail.html, and put the comment_form.html's code there, however this did not work. Here are the relevant views.py The add_comment_to_post view @login_required(login_url='/mainapp/user_login/') def add_comment_to_post(request,pk): post = get_object_or_404(Post,pk=pk) if request.method == 'POST': form = CommentForm(request.POST) if form.is_valid(): comment = form.save(commit=False) comment.post = post comment.author = request.user # add this line comment.save() return redirect('mainapp:post_detail',pk=post.pk) # remove `def form_valid` else: form = CommentForm() return render(request,'mainapp/comment_form.html',{'form':form}) Here is the PostDetailView view. class PostDetailView(DetailView): model = Post Here is the comment_form.html code <form class="post-form" method="post"> {% csrf_token %} {{ form.as_p }} <button type="submit" class="submitbtn">Comment</button> </form> And here is the relevant urls.py files path('post/<int:pk>/comment/', views.add_comment_to_post, name='add_comment_to_post'), path('post/<int:pk>', views.PostDetailView.as_view(), name='post_detail'), So at the moment, when doing my solutions I thought would work, I added the comment_form.html's code into the post_detail.html document, however it only showed … -
Django Templates - Check and Uncheck Checkbox
I have a django Task with a todo list inside it, this is a list of strings and checkboxes. When I tap a checkbox it changes value but doesn't send it to the model via a POST request. What I want to do is create two views, one that makes the value in the model Checker to 'True' and one that makes it 'False'. These are my Task and Checkbox Models: class Task(models.Model): name = models.CharField(max_length=150) description = models.CharField(max_length=1000) state = models.CharField(max_length=15) deadline = models.DateField(default=date.today) workers = models.ManyToManyField(UserProfile, blank=True, related_name="task") stickers = models.ManyToManyField(Sticker, blank=True, related_name="task") checkers = models.ManyToManyField(Checker, blank=True, related_name="task") files = models.ManyToManyField(File, blank=True, null=True) class Checker(models.Model): name = models.CharField(max_length=100) checked = models.BooleanField(default=False) This is the view To create a checkbox: @login_required def create_checker(request, task_id): if request.method == 'POST': name = request.POST.get('Checker-Name') userprofile = UserProfile(id=request.user.id) checker = Checker(name=name, sender=userprofile) checker.save() task = Task(id=task_id) task.checkers.add(checker.id) return redirect('detailTaskPage', pk = task_id) I want to do something like this when I check versus uncheck the boxes: //Check @login_required def check_checker(request, task_id, checker_id): if request.method == 'POST': checker = Checker(id=checker_id) checker.save() checker.checked=True checker.save() return redirect('detailTaskPage', pk = task_id) //Uncheck @login_required def un_check_checker(request, task_id, checker_id): if request.method == 'POST': checker = Checker(id=checker_id) checker.save() checker.checked=False checker.save() … -
Django files upload causes memory leak
I have an observation about memory leak: If we try to POST files to Django view, Django will not release memory even a response has been made. The memory will keep rising if you keep uploading files even if you do nothing in views.py. (I have tried uploading 100 files concurrently calling the same API). I know that if an uploaded file is smaller than 2.5 megabytes, Django will hold the entire contents of the upload in memory. So I am wondering this could be an issue for a possible memory leak because it will never release the memory. PS: Even if I set FILE_UPLOAD_MAX_MEMORY_SIZE=0, which means use disk to store the files instead of using memory, I can still see a memory rise at the background. Does anyone know how to solve this issue ? Thanks a lot. -

Looking for an alternative way to filter my objects before using a django-filters class
I've implemented a filter using the django-filters third party framework but want to run the filter on an already filtered set which was giving errors. class BlogView(ListView): template_name="blog/blog.html" model = Post # def get_queryset(self): # return Post.objects.filter(posted_date__lte=timezone.now()).order_by("-posted_date")[:25] def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['filter'] = PostFilter(self.request.GET, queryset=self.get_queryset()) return context my view ^ my filter v class PostFilter(django_filters.FilterSet): class Meta: model = Post fields = ["title"] My blog needs the ability to schedule posts in the future meaning when i display them i am filtering posts by posted_date__lte=timezone.now() however this is causing a problem when i am then using the filter because i cannot filter an already spliced object. I've read through and understand the problem comes from the way the database works so i am looking for an alternative way to make only posts that posted_date__lte=timezone.now() show without using the currently commented out def get_queryset filter i was previously using. -
Django test: cannot find object already created
My goal is to have a sort of generic function that creates a row only if this one doesn't exists. A bit of an extension of [get-or-create][1] When I create self.created_object in the setUp, I get an id for the object, which seems to be the definition for an object being persisted on the database. However, when I then try to query MyObject.objects.all(), I get an empty set. The test fails, and the error I get is the following: AssertionError: UUID('b8680f60-1fc0-4bc5-8a26-735ee43247ea') != UUID('38d9b535-2f12-4e76-b637-d52030798f3d') Here's a simplified version of what I'm trying to do from django.test import TestCase from app.models import MyObject from utils import get_object_or_create_it # the implementation is not relevant here class TestCreateOnlyIfNotExists(TestCase): def setUp(self): self.created_object = MyObject.objects.create( name="nobody_cares" ) def test_get_object_or_create_it(self): create_object_only_if_exists = get_object_or_create_it( {'name': 'nobody_cares'}, ('name',), MyObject, ) self.assertEqual( self.created_object.id, create_object_only_if_exists.id ) [1]: https://docs.djangoproject.com/en/dev/ref/models/querysets/#get-or-create Any idea of what's going on here? -
How to create a Enterprise Application with Django
I love to create webapps with Django. I would like to develop an app exclusively for my company. That means no access for people outside the company. Because I'm the only developer, I need a solution that focuses on developing rather than administrative work. Heroku and Azure are good for deploying django but I do not know, how to create a network, that only interacts with the employees of my company. Running a own web server like Apache in the internal company network is also a solution, but I have no skills for it. The appidea: Djangoapp is showing data from a SQL Database. My company mainly works with Microsoft. I am very happy about suggestions -
Error while updating user group in django?
Here I am trying to add/update group name and user permissions and i tried like this. For add it is working fine but while updating with function edit_user_group i got problem.

How to give full access (= anyone) POST to a JWT view?

Online collaborative list of references
I am working in academia in a very wide field of research mixing a lot of different domains. This broadness is also a problem, since there is no proper references for the basis of the theory, and we have to deal with a lot of material scattered in very different places, often in the form of lecture notes, conference proceeding or unpublished documents. Therefore, I would like to propose a collaborative online list of these references, in a light way so that anyone could add or improve the list. The best current list of references is here, which is neither up to date nor really easy to use (no tags, list by authors, etc). I would like something slightly more powerful, I though about some framework like Django but don't really know if it is a suitable solution. I would like to be able for anyone to sort in different ways add tags add or edit references entries rate difficulty (this is a bonus) comment (this is a bonus) Moreover, it should be better if the list were accessible without any amount on a simple webpage. Any suggestion is welcome! -

Django - saving manually generated ImageField raises error
I have anInvoice model which has qr_code = ImageField(...) field. In save method, I want to generate the qr_code file and save it to the field. The problem is a path. When I set path including /media/ - so /media/qr/myfile.png, Django then looks for it in templates this way: /media/media/qr/myfile.png. But when I not include /media/ it cannot be saved: FileNotFoundError: [Errno 2] No such file or directory: 'qr/myfile.png' I think the problem is either in first function or at the end of the other.

jQuery Core test/data/jsonp.php callback Parameter XSS
jQuery Core contains a flaw that allows a cross-site scripting (XSS) attack. This flaw exists because the test/data/jsonp.php script does not validate input to the 'callback' parameter before returning it to users. This may allow a context-dependent attacker to create a specially crafted request that will execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server.| Which version of jquery or django-jquery have this fix? -

Can I make it create multiple records for storing multiple answers instead of using a M2M? e.g. if a student select A and B for a question, would act like the following: StudentAnwer.objects.create(question=question, answer=answer_a) StudentAnwer.objects.create(question=question, answer=answer_b) formsets.py from django import forms StudentAnswerFormSet = forms.inlineformset_factory( Student, StudentAnswer, fields=['question', 'answer', ], formset=forms.BaseInlineFormSet) models.py class Question(BaseModel): title = models.CharField(max_length=250) is_multiple = models.BooleanField(default=False) class StudentAnswer(BaseModel): student = models.ForeignKey(Student, related_name='answers') question = models.ForeignKey(Question, related_name='student_answers') answer = models.ForeignKey(Answer, related_name='student_answers') views.py from formtools.wizard.views import SessionWizardView class StudentWizardView(SessionWizardView): ... def get_answer_form(self, step=None, data=None, files=None): ... question_list = get_question_list() return forms.inlineformset_factory( Student, StudentAnswer, fields=['question', 'answer', ], extra=len(question_list), formset= forms.BaseInlineFormSet) def get_form(self, step=None, data=None, files=None): form = super(StudentWizardView, self).get_form(step, data, files) # determine the step if not given if step is None: step = self.steps.current if step == self.STEP_ANSWER: initial_dict = self.get_form_initial(step) prev_form_data = self.get_cleaned_data_for_step(self.STEP_PROFILE) form = self.get_answer_form(step, data, files) for form_index in range(len(initial_dict.keys())): question = initial_dict[form_index]['question'] answer_list = question.get_answer_list() if question.is_multiple: form.forms[form_index].fields['answer'] = ModelMultipleChoiceField(queryset=answer_list, widget=CheckboxSelectMultiple) else: form.forms[form_index].fields['answer'].widget.choices.queryset = answer_list I'm trying to avoid M2M for making it easier to display the possible answers per question on the template. {{ wizard.management_form }} {{ wizard.form.management_form }} {% …
