How to limit catch all urls in django
I have a django project with specific urls, setup by a 'catchall' URL. This is so I can go to mysite/living, and have it pass living as a parameter and pull up the appropriate details from my db. My urls.py: url(r'^$', views.index, name='index'), url('about/', views.about_view, name='about_view'), url('contact/', views.contact_view, name='contact_view'), url('(?P<colcat>[\w\-]+)/collection/(?P<name>[\w\-]+)$', views.collection_detail, name='collection_detail'), url('(?P<colcat>[\w\-]+)/$', views.collection_view, name='collection_view'), I am running into the problem where, anything can be passed as a parameter. This is particularly notable with search engines, where mysite/index.html/index.html returns a valid page. Is there a way to limit the urls that are 'allowed' to be matched? -

I try to order my form (in django) but it doesnt work. I tryed some ways but nothing helps. I tryed for example with SortedDict from django.utils.datastructures.

Django: Can't GROUP BY on a template table
I'm trying to show a table in the template, which shows transactions with their dates. The query is: resultado = Asiento.objects.filter(Empresa=request.session['codEmp'], codcta=cod_cta).exclude(anulado='S').order_by(date) But the user can check a checkbox which if set to true should show one row per date in the table. Without group by: +-------------------------------+-------+ | date | trans_in | trans_out | total | +--------+----------+-----------+-------+ |2019/5/3| $5.000 | $0 | $5.000| +--------+----------+-----------+-------+ |2019/5/3| $0 | $2.500 |-$2.500| +--------+----------+-----------+-------+ |2019/5/4| $1.000 | $0 |$1.000 | +--------+----------+-----------+-------+ And what I'm trying to do is: +-------------------------------+-------+ | date | trans_in | trans_out | total | +--------+----------+-----------+-------+ |2019/5/3| $5.000 | $2.500 |$2.500 | +--------+----------+-----------+-------+ |2019/5/4| $1.000 | $0 |$1.000 | +--------+----------+-----------+-------+ I've already tried by doing resultado = Asiento.objects.filter(Empresa=request.session['codEmp'], codcta=cod_cta).exclude(anulado='S').order_by(date).values('date').annotate(dcount=Count('date')) Using annotate but it doesn't work! I really can't figure yet how to group by easier. Later in the code I iterate with a for loop over resultado to add and substract the amount of money for each object in the queryset. for asiento in resultado: add = add+asiento.add sub = sub+asiento.sub asiento.total = asiento.add-asiento.sub total = add-sub -
Pre-populate slug field into a form field of a Django site
I've create a form for publish a post on a site. Into the model there is a SlugField that is a pre-populated field in admin.py for the title of the post. forms.py class TestPostModelForm(forms.ModelForm): title = forms.CharField( max_length=70, label="Titolo", help_text="Write post title here. The title must be have max 70 characters", widget=forms.TextInput(attrs={"class": "form-control form-control-lg"}), ) slug_post = forms.SlugField( max_length=70, label="Slug", help_text="Slug is a field in autocomplete mode, but if you want you can modify its contents", widget=forms.TextInput(attrs={"class": "form-control form-control-sm"}), ) ..... class Meta: model = TestPostModel fields = [ "title", "slug_post", "description", "contents", .... ] If I create a post from the administration panel the slug is correctly populated automatically, but the same thing don't happen if I create a post from the form. In this second case the post is created but the slug field remain empty. I've read that I must use slugify for create a pre-populated field into my form but I have not clear in which method I can do this. Can I have some example? -

Is there a way to have rest framework return a type of error not only a type of response for form validation?
I am new to frontend development. Now I am creating a form using VueJS and I created backend using Django. What I want to do is to show validation error message below form just like Django form does. However, Rest framework is supposed to return just the type of the response like 400 when the user send invalid data and I'm wondering if there's a way to show various error messages depending on the type of the invalid data the user sent. For example, when user input incorrect password, I want to show Password is incorrect. But I think I need to get the type of error from backend in order to achieve this kind of thing. Anyone could give me tips? -

How to access stored user data in django?
I'm new to django, especially the storing of user data. Basically, I want to save user data searches. They put in a query into a search_bar and I want to save that query. I'm trying to create a list for each user with their search queries at user['search'] and the results of these queries at user['results']. However, I added some code and it does not seem to save the results. Here is my code for user['results']. It's the same as for user['search']. I'm trying to save the query results by using request.session['result'] = query_result. The reason the results are not obvious is that they make a few choices between entering the query and seeing results. from django.contrib.sessions.models import Session request.session.modified = True object_save = list(_objs.values('service__code')) if not 'result' in request.session or not request.session['result']: renderequest.session['result'] = [object_save] request.session.save() else: result_list = request.session['result'] result_list.append(object_save) request.session['result'] = result_list request.session.save() I'd expect this to be able to save and I can look at the searches in python manage.py shell. When I try to pull all the session data with s = Session.object.get(pk='pk') and s['result'] I get nothing. s has no attribute 'result' is the error. Maybe I'm completely not understanding user sessions, please help. -
