Sending a POST request through Javascript on Django - failed to retrieve data
I'm trying to send a POST request to my Django view using plain javascript (I don't want any unnecessary libraries involved). The data is not sent through a form, but by using fetch. For now I just want to be able to manipulate the request.POSTin my views.py, nothing more. Here's my code: Javascript let article = document.querySelector('article') articleId = article.getAttribute('data-product-id') # some other stuff fetch("{% url 'shop:shoplist' 1 %}", { method: 'POST', dataType: "application/json", data: {'article_id': articleId}, headers: {'X-CSRFToken': csrf_token} }) Python if request.method == 'POST': testing = request.POST return JsonResponse({'test': testing}) The request is sent, the csrftoken is received correctly, but the request.POST returns just <QueryDict: {}>, instead of what I'm expecting (headers, data...). I've searched and found a lot of similar questions, the most similar one being this one, but still I can't seem to find a solution. Any idea? -
How to render ete3 tree in django template?
I'm very new in django and ete3 toolkit programming. I want to generate phylogenetic tree with ete3 toolkit in views.py and render tree's svg image to template.

Django - How can I manage custom payments between users on my platform with Stripe?
I'm trying to create a platform with multiple functionalities, and one of them is a crowfunding of projects, in which the users can post a project and ask for funds. (like kickstarter or indiegogo). I'm working with Django 2.0, Python 3.6 and PostgreSQL and I want to use Stripe for payments. I also read a bunch of the Stripe's API Documentation, and I have some ideas for doing this, but this will be my first API implementation so I would like to do it well (more even talking about payment systems). The main question is: How can I do that multiple users realize payments to another for one project ONLY when the goals of that project are reached? What I think that is the better is to use (Stripe Connect) Express/Custom Accounts to create an account for each user that posts a Project, so I can redirect all the payments to that account. The thing is that I also want to apply a fee for my platform. And I don't know exactly how can I do this. I imagine that Stripe give an option for that to evade doing two transactions in my own backend (one for the project's user β¦ -

Check in a Django template if all parameters are available for URL-generation (#NoReverseMatch)
Description I have a HTML template that is used by several views. It's all the same but one HTML link is different. So I thought about checking in the template what's the request.path and change the link accordingly. Problem Because not all parameters are passed to the template by all views I get an NoReverseMatch. This was my idea for the template: {% url "first" as first_url %} {% if first_url in request.path %} <button type="button" onclick="$.get("{% url 'foo' a b c %}");">Foo</button> {% endif %} {% url "second" as second_url %} {% if second_url in request.path %} <button type="button" onclick="$.get("{% url 'bar' a %}");">Bar</button> {% endif %} Question Is there a way to use Django's {% url %} though not all parameters are available? Or do you need to extend the template? -
Changing table name of a model in view
I need to change the table name of a model during the process: in my view: def list_tables(request, *args, **kwargs): for suffix in range(0, 100): my_model._meta.db_table = "table_name_{}".format(suffix) print(my_model.objects.all().query) and the result is: SELECT "table_name_0"."field_1", "table_name_0"."field_2" from "table_name_0" SELECT "table_name_0"."field_1", "table_name_0"."field_2" from "table_name_1" So when I change the _meta.db_table in process, it changes the table names in select and from statement in the first query, but in the second query it changes from statement but the table name in select remains as in previous table_name. So I got this error in second query: django.db.utils.ProgrammingError: missing FROM-clause entry for table "... Anyone has any offer for me? -
Getting 3 previous items in django queryset
I know there are similar questions but they don't answer mine. Say I have a sequence of letters: A B C D E F G I want to pass only 3 letters to my template based on a specific letter, and those 3 letters must be previous ones. For example, If this letter is D then it must be: A B C If it's E then it's: B C D and etc. I understand the way slicing works but all I can do is to get the first 3 letters of my query set: context['words'] = WordsAndLetters.objects.exclude(letter=letter).order_by('letter')[:3] I'm also excluding my specific letter to just show 3 previous. How can I get to the right result? -
How to get key(column name)-value pair from a Select query using default connection in Django
I have 4 application in one Django Project. I am using the default Postgres database connection which I have included it in my setting.py file. The object django.db.connection represents the default database connection. To use the database connection, I call connection.cursor() to get a cursor object. Then, call cursor.execute(sql, [params]) to execute the raw Postgres queries and cursor.fetchone() or cursor.fetchall() to return the resulting rows. Now, in one application I want to use the (connection.cursor(cursor_factory = psycopg2.extras.RealDictCursor)) to get the records in a key(column name)-value pair, which is provided by psycopg2.connect but the default connection that I have is not compatible with cursor_factory = psycopg2.extras.RealDictCursor. How do I get a key(column name)-value pair from the database by using the default connection? from django.db import connection cur = (connection.cursor(cursor_factory = psycopg2.extras.RealDictCursor) cur.execute("SELECT * FROM sometable") data= cur.fetchall() ERROR: cursor() got an unexpected keyword argument 'cursor_factory' -
django request transport to custom database backend
My team is developing secure django project and we stacked with transport Django request into custom database backend. We made such an algorithm for GSSAPI(SPNEGO) authentication in django and delegating user credentials for server querying on behalf of user: if 'HTTP_AUTHORIZATION' in request.META: kind, initial_client_token = request.META['HTTP_AUTHORIZATION'].split(' ', 1) if kind == 'Negotiate': server = 'HTTP@server.domain.ru' _ignore_result, krb_context = kerberos.authGSSServerInit(server) kerberos.authGSSServerStep(krb_context, initial_client_token) principal = kerberos.authGSSServerUserName(krb_context) _ignore_result = kerberos.authGSSServerStoreDelegate(krb_context) conn = psycopg2.connect( host='krb5-dbhost', user=principal, dbname='db', ) cursor = conn.cursor() cursor.execute("SELECT version()") records = cursor.fetchall() this works well in django-view. Kerberos server can authorize user and cache krb5-ticket for credentials delegation to query in psycopg. Now we need to inject it into django. We want is inherit postgresql database backend like this: from django.db.backends.postgresql_psycopg2.base import DatabaseWrapper class CustomDatabaseWrapper(DatabaseWrapper): def __init__(self, *args, **kwargs): super(CustomDatabaseWrapper, self).__init__(*args, **kwargs) def get_connection_params(self): '''We need to customize this function, We need get request here when query processed by web interface,''' #.... the source code could be here, but it is not necessary return conn_params So the question is: "How can we get request.META (for get user`s Negotiate token) in get_connection_params() function, and how can we divide users request from web interface from management commands."

Django: using html templates TemplateDoesNotExist
I've been writing my first Django app and hit a problem with using templates. No matter how I format the url for the template I receive the TemplateDoesNotExist error. My html is nest in views/ with the core template being views/template.html. I have tried: myapp/views/template.html views/template.html templates/views/template.html <full path to app>/<all variations> None of which can locate the template. I understand the TEMPLATE_DIRS variable may be set at project level but this is app-specific and the views/ directory is not purely for templates. I don't think I should add to the url_patterns since the template shouldn't be accessible directly. I've got this far without them but need to clean up the app. Any advice? -

Tips on speeding up django views?
I am trying to do some data analysis for a company(sales, stock, yearly progression and so on). However, I'm finding that the calculation time is enormous(almost 1 minute for a single page with a single line graph). I'ce already checked the queries and they take around 2 seconds(still a lot, but whatever). Using django-debug-toolbar, I've seen that request rendering(which I suppose is the page's view) takes around 50 seconds. Do you guys have any idea of how I could Speed that up? This is the code: Main function for the graph: def get_data_progression(years): result = {} for year in reversed(years): result[year] = { "uscite": 0, "entrate": 0, "magazzino": { "val": 0, "nbr": 0 }, "valorizzazione": 0, "months": [] } for i in range(1, 13): entrate = 0#get_entrate_month(year, i) uscite = 0#get_uscite_month(year, i) m_val, m_nb = get_magazzino_month(year, i) result[year]["months"].append({ "entrate": entrate, "uscite": uscite, "magazzino": m_val, }) result[year]["entrate"] = entrate result[year]["uscite"] = uscite result[year]["magazzino"]["val"] = m_val result[year]["magazzino"]["nbr"] = m_nb result[year]["valorizzazione"] = result[year]["magazzino"]["val"] + result[year]["entrate"] - result[year]["uscite"] return result And this is the function I am trying to optimize.

Handle POST/GET forms with Django

In my template, user can choose some documents, submit the list of documents which is picked up to a Django form (CustomerForm) in my modal. This CustomerForm lets to send an email with user informations previously filled. My CustomerForm looks like this : class CustomerForm(forms.ModelForm): def __init__(self, *args, **kwargs): super(CustomerForm, self).__init__(*args, **kwargs) self.fields['country'].empty_label = _('Select a country') self.fields['country'].queryset = self.fields['country'].queryset.order_by('name') self.fields['email'].required = True self.fields['first_name'].required = True self.fields['last_name'].required = True self.fields['country'].required = True self.fields['institution'].required = False class Meta: model = Customer fields = ['email', 'first_name', 'last_name', 'country', 'institution'] widgets = { 'email': forms.TextInput(attrs={'placeholder': _('name@example.com')}), 'first_name': forms.TextInput(attrs={'placeholder': _('First Name')}), 'last_name': forms.TextInput(attrs={'placeholder': _('Last Name')}), 'institution': forms.TextInput(attrs={'placeholder': _('Agency, company, academic or other affiliation')}), } I have views.py file : class HomeView(CreateView, FormView): """ Render the home page """ template_name = 'index.html' form_class = CustomerForm def get_context_data(self, **kwargs): # display some things # ... if "DocumentSelected" in self.request.GET: checkbox_list = self.request.GET.getlist('DocumentChoice') document = Document.objects.filter(id__in=checkbox_list) kwargs['selected_document'] = document return super(HomeView, self).get_context_data(**kwargs) def form_valid(self, form): email = form.cleaned_data['email'] country = form.cleaned_data['country'] for checkbox in self.request.GET.getlist('DocumentChoice'): document = Document.objects.get(id=checkbox) token = self.gen_token(email) now = timezone.now() expiration = now + settings.DOWNLOAD_VALIDITY β¦ -
