Django Reverse with a named url
I feel like this is one that I shouldn't be having trouble with, but I'm stumped. I tried to Google around, but the every post I see has the issue in the template. I have the following in urls.py: path('AddStudent/thanks', views.thanks, name='AddStudentThanks') I have an FBV from another view that I want to link to that one. I can do it explicitly with return HttpResponseRedirect("AddStudent/thanks") but when I try to future-proof it and use the named url with the following code return HttpResponseRedirect(reverse("AddStudentThanks")) #go I get the following error & traceback NoReverseMatch at /advising/AddStudent Reverse for 'AddStudentThanks' not found. 'AddStudentThanks' is not a valid view function or pattern name.

Django MultipleModelChoiceField gives me a ProgrammingError
I would like to get your help because I'm getting an issue which is a little bit weird to my mind. I'm using Django 1.11.16 I have in my forms.py file this class : class PublicationStatForm(forms.Form): # publication_list = forms.ModelMultipleChoiceField(queryset=Publication.objects.all().order_by('pub_id')) publication_list = forms.ModelMultipleChoiceField( queryset=Publication.objects.all().order_by('pub_id'), label=_('Publication Choice'), widget=ModelSelect2Widget( model=Publication, search_fields=['pub_id__icontains', 'title__icontains'], attrs={'data-placeholder': "Please select publication(s)"} ) ) def __init__(self, *args, **kwargs): super(PublicationStatForm, self).__init__(*args, **kwargs) Then, in my views.py file : class StatsView(TemplateView): """ Create statistics pageview """ template_name = 'freepub/stats.html' form_class = PublicationStatForm def get_context_data(self, **kwargs): subtitle = _("Statistics") context_data = super(StatsView, self).get_context_data(**kwargs) context_data['form'] = self.form_class() ... return context_data And finally in my template, I just have : <form class="date-form" method="GET"> <div class="row"> <div class="col-md-7"> {{ form.publication_list }} </div> </div> <input id="submit-date-stats" type="submit" class="btn btn-default" name="SearchPublicationPeriod" value="{% trans 'Submit' %}"/><br/> </form> I don't understand why, when I have this line in my form it works : # publication_list = forms.ModelMultipleChoiceField(queryset=Publication.objects.all().order_by('pub_id')) But when I replace this line by this : publication_list = forms.ModelMultipleChoiceField( queryset=Publication.objects.all().order_by('pub_id'), label=_('Publication Choice'), widget=ModelSelect2Widget( model=Publication, search_fields=['pub_id__icontains', 'title__icontains'], attrs={'data-placeholder': "Please select publication(s)"} ) ) I get this issue : Exception Type: ProgrammingError at /freepub/stats Exception Value: relation "select_cache" does not exist LINE 1: SELECT COUNT(*) FROM "select_cache" ^ Do you β¦ -
django testing Assertquerysetequal not working
I have trying to do an assertqueryset with django testing using the following commands but all of them work if there is only one object in the list, but when I insert multiple objects in the list to compare both sets of queries all of them fail sometimes and pass sometimes which is completely strange(running with same set of code). The list of assertquerysetequal I used to test I sourced from two other questions in How do I test Django QuerySets are equal? and in Django 1.4 - assertQuerysetEqual - how to use method as well as the django documentation. This could be because the sequence is not in order when it fails the comparison test. Because when I did a print - my querysets were exactly matching. Because when I run the tests, sometimes the tests passes, sometimes it fails when I compare multiple objects in my lists. I can tell them the list differ when it fails because of the error message but I don't understand why the commands that I used does not compare them in order. (They were accepted/upvoted answers) Any advice on how I can fix this permanently would be welcome. Thank you. class TestViews(TestCase): β¦ -

Django: creating a text with gaps for input
I want to create a text on my website, where the gaps, in which the user can input a word (like the c-tests for learning language) are dynamically created depending on the text that the function gets from the database (not yet implemented). My idea was it to create a formset in which each label is different depending on a variable I give it. Here is my views.py def ctest(request): c_test_tokens, gaps, tokenindexe = generate_c_test(beispieltext()) # EXAMPLE # NOT WORKING ON POST REQUEST YET # if this is a POST request we need to process the form data if request.method == 'POST': # create a form instance and populate it with data from the request: form = CTestform(request.POST) # check whether it's valid: if form.is_valid(): # process the data in form.cleaned_data as required # ... # redirect to a new URL: return HttpResponseRedirect('/thanks/') # if a GET (or any other method) we'll create a blank form else: CTestform.creatingForm(tokenindexe) ctestformset = formset_factory(CTestform, extra=len(gaps)) return render(request, 'ctest.html', {'form': ctestformset}) Here is my forms.py class CTestform(forms.Form): hello = forms.CharField(widget=forms.TextInput(attrs={'size': '5'}), required=False, label='hello', label_suffix='') Is this approach fine and how do I give the form a list with each element being the label for β¦ -

Django Forms - How to create a "Save and New" button?
Is there a way in Django Forms that I could implement a button "Save and New"? For example: I'm registering a new Book, I have both "Save" and "Save and New" buttons in the HTML template. The "Save" button behaves normally. You put the data in the form fields, click on it, the new object is created and saved and then redirects to the list of books. But I would like that the "Save and New" button redirects to the same form creation page after clicked. Plese, how could I do that? I didn't find anything about this in the docs. -
ImportError: cannot import name 'X' - Compile Python class with Cython
I'm creating a web application (using Django 1.11.2, Python 2.7.15) that will be deployed in a IIS server (actually now I'm only working on my local PC with Windows 10). Since that server will be reachable by another user and since I need to protect the application's back-end, I compiled the Python's core classes with Cython getting the ".pyd" files.

Multiple Models in Django-filter 1.1.0
I'd like to implement a filter for the end user of the site, so that they can filter by price, rating, gender and location. The problem here is that price and rating are stored in the models class "comment" and the location and gender in the models class "adventure". In the class "comment" the "adventure" is referenced by a foreign key. How can I use Django-filter 1.1.0 in my filters.py to address both models "comment" and "adventure" that reference each other, to filter according to the above mentioned arguments? Here is my code that works, but only filters the class "adventure".
