`TypeError: argument 2 must be a connection, cursor or None` in Psycopg2 with Django on Heroku
I have a heroku pipeline set up, and have just enabled review apps for it. It is using the same codebase as my staging and production apps, same settings files and everything. When the review app spins up, it can connect to the created DB and run migrations. When I try to connect to the app in the browser, I get `TypeError: argument 2 must be a connection, cursor or None` in `psycopg2/_json.py, register_json:139` Top of stack is: `django.contrib.sites.models._get_site_by_id`. I've attached the Opbeat output of the error frame at the bottom of this post. Settings file is linked. When I set DEBUG=True, everything works fine. Which might suggest an ALLOWED_HOSTS issue, but when I set ALLOWED_HOSTS to '*' with DEBUG=False, it still errors? What is wrong with my setup? This works in staging, and production, but not the review apps. -

How to get django-autocomplete-light to work with smart selects (in 2016)?
I just got organization, a ForeignKey field that is affected b django-autocomplete-light to work, however office location, the following dropdown field, should be populated with an organization's office_locations via smart selects. Instead it returns -----, the signifier for no available choices. models.py class Person(models.Model): ... organization = models.ForeignKey(Organization, related_name='people') office_location = ChainedForeignKey( OfficeLocation, chained_field='organization', chained_model_field='organization', related_name='people', null=True, auto_choose=True, ) class OfficeLocation(models.Model): organization = models.ForeignKey(Organization, related_name='office_locations') ... autocomplete_view.py class OrganizationAutocomplete(autocomplete.Select2QuerySetView): def get_queryset(self): if not self.request.user.is_authenticated(): raise PermissionDenied results = Organization.objects.filter(name=self.q) if len(results) > 0: return results else: return Organization.objects.filter( Q(name__icontains=self.q) | Q(pseudonyms__icontains=self.q) | Q(website__icontains=self.q) ).order_by('name') urls in #urls.py url patterns = [ url(r'', include('contacts.urls', namespace='contacts')), url(r'^chaining/', include('smart_selects.urls')), ] # in contacts/urls.py url( r'^organization_autocomplete/$', OrganizationAutocomplete.as_view(), name='organization_autocomplete', ), forms class PersonForm(forms.ModelForm): class Meta: model = models.Person fields = "__all__" widgets = { 'organization': autocomplete.ModelSelect2( url='contacts:organization_autocomplete', attrs={'data-minimum-input-length': 3}, ) } Some digging revealed a response from 2012 says that won't work together, in which some made the workaround # in urls.py from smart_selects.widgets import ChainedSelect ChainedSelect.Media = None but adding the snippet hasn't solved the issue.

Django - How to save an object from a model in a view
I'm running Django 1.10 on Python 3.7. I have a problem when I try to save an object from a model after applying a function on it. What I want to do is just to substract a certain amount of money (this amount is stored is the class (klient) attribute argent). So I created a method called acheter in this class with an argument id_achat to be able to substract different amounts of money. When I run the command a.acheter(id) (where a is a klient object and id_achat an integer) in the shell, everything is OK, the substraction has been done when I look at a.argent. However, in interface_du_klient.html, I put some links to redirect the user to a view called achat. In this view I call the acheter method on my klient object called with the get_object_or_404 method, but the attribute argent of this klient object is not modified. Here you can see my models.py : from django.db import models from django.contrib import admin import decimal class klient(models.Model): id_klient=models.CharField(max_length=100, primary_key=True) nom=models.CharField(max_length=100) prenom=models.CharField(max_length=100) argent=models.DecimalField(decimal_places=2,max_digits=4) membre=models.IntegerField() # 0 pour non membre, 1 pour membre KFet date = models.DateTimeField(auto_now_add=True, auto_now=False, verbose_name="Date d'enregistrement") nombre_biere=models.IntegerField(default=0) nombre_pinte=models.IntegerField(default=0) nombre_cafe_ou_the=models.IntegerField(default=0) nombre_canette=models.IntegerField(default=0) def __str__(self): return "{0} {1}".format(self.nom,self.prenom) def … -
Django session is not deleted after logout
I recently discovered that the logout functionality of my Django app seems to be broken. I believe it worked in the past, but I cannot figure out why it is not working now. That's my setup: index.html: ... {% if request.user.is_authenticated %} <a style="position: absolute; top: 0; left: 0;" href="{% url 'auth_logout' %}">Logout</a> {% else %} <a style="position: absolute; top: 0; left: 0;" href="{% url 'auth_login' %}">Login</a> {% endif %} ... urls.py: ... from django.contrib.auth import views as auth_views ... urlpatterns = [ ..., url(r'^accounts/logout/$', auth_views.logout, name='auth_logout'), url(r'^accounts/login/$', auth_views.login, name='auth_login'), ... ] Templates: login.html: {% extends 'simple_logo_base.html' %} {% block content %} <div class="row"> <div class="col-md-3"></div> <div class="col-md-6"> <h2>Login</h2> {% if next %} <form action="/accounts/login/?next={{next}}" method="post" > {%else%} <form action="/accounts/login/" method="post" > {% endif %} {% csrf_token %} {{ form.as_p }} <button type="submit">Login</button> </form> </div> <div class="col-md-3"></div> </div> {% endblock %} logout.html: {% extends 'simple_logo_base.html' %} {% block content %} <h2 class="text-center">Logged out</h2> {% endblock %} Where "simple_logo_base.html" is just the plain html structure with a div containing a logo.

Datatables - Individual Column Sort not working in Django
Im trying to implement the Individual column sort in my django project. I am able to convert the table into a datatable and the search bar that is displayed works perfectly in searching the table. I modified the code shown in the link a little to allow sorting only selected columns via the select dropdown and also have the select dropdowns appear in a different div. I was able to get the select dropdown in the div: However When I select an option form the dropdown the table displays no matching records found , when clearly data matching the criteria exists. Any help in figuring out the issue will be greatly appreciated. Code is pasted below: $(document).ready(function () { $('#audience-list').DataTable({ initComplete: function () { this.api().columns([1]).every(function () { var column = this; var select = $('<select><option value=""></option></select>') .appendTo($("#sort")) .on('change', function () { var val = $.fn.dataTable.util.escapeRegex( $(this).val() ); column .search(val ? '^' + val + '$' : '', true, false) .draw(); }); column.data().unique().sort().each(function (d, j) { select.append('<option value="' + d + '">' + d + '</option>') }); }); } }); }); -
use DATABASES while loading settings of django
I need to use inside django's settings.py: ... DATABASES = {...} def get_domain(): from django.contrib.sites.models import Site return Site.objects.get_current().name sth=get_domain() ... DATABASES = {...} # overwrite, which doesnt work ... My settings.py is complex with loading customized settings as well, so the order cannot be changed. The problem is that above function will actually load DATABASES somewhere to django's db layer and it is impossible then to overwrite that with second DATABASES. How to inform django that DATABASES (and only this!) should be loaded again? -
django-leaflet does not appear to allow circle drawing
I'm using django-leaflet and django-geojson in my project, it is on github at: https://github.com/makinacorpus/django-leaflet Using the widget for the Django Admin (LeafletGeoAdmin) I can draw polygon shapes, or rectangle shapes, that I then store as geojson in my models. The leaflet examples I've seen (outside of django) also have a circle shape available (I think it produces a "Circle marker"), but it does not appear as an option here. I can't find any info about adding shape types, in readme/tutorials. Is it possible to do? -

How to merge multiple QuerySets in django?

For a given employee, I would like to retrieve the latest LogEntry for all log_types that the given employee has created. I have seen examples using annotate to grab the latest for all employees, or the latest for all log_types, but not one that restricts on one field, while annotating on another.

Django - trouble with grouping in table and rowspan

Its hardcoded on the rowspan that's why and dont know how to make it more universal. I want to rowspan by various numbers. If the same lift occurs more than one time i want it to rowspan by number of occurrences. And this is from views.py: def lift_date(request, pk): date = get_object_or_404(Dates, pk=pk,) excercises = Lifts.objects.filter(user=request.user).order_by ('created_date__created_date') return render(request, 'lift/lift_date.html', {'date': date, 'excercises': excercises}) Right now it looks like this:That's how this table should look like If I have 3 "bench presses" I want to show them as one row. But if add other lifts eg single squat it will look like this I know it is because of my way for coding rowspan but I dont know how to do it other way Is there a way to make rowspan depend on number of occurrences? -

Hi guys I hope you can help me to solve this doubt, I have a form and I render on my template a select with several options related to another model, something like {{form.selectfield}} and also I have in the same template a modal to add a new option to my select field in which I make a post through jquery ajax and get a response to display a success or error message, it's posible to reload or refresh the rendered select to add the new option without reloading the page to render again the field?

Nginx redirect to 404 dynamic custom template
I'm currently a problem for which I run out of solutions: Quickly resume: The project is write with Django, I have my custom 404 configured correctly and I have some specific urls that are stuck to the nginx 404 rendering instead of my django template. Example: mydomaine.org/en/%20 My django 404 is a template, which means that it's dynamically link to a page within the CMS. I don't have a custom 404.html (or, let's say its writes with {% myheader %} etc ) So, here is my first try: rewrite ^/en/\s.*$ mydomain.org/en/404 permanent; but this return a 302 code and doesn't take the language in consideration. So I tried something else: error_page 404 /404.html; (but of course I don't have a proper template whatever) location ~ /(?:en|fr|de|es|tr|ja)/\s.* { return 404 mydomain.org/$1/404; } doesn't work. location ~ /(?:en|fr|de|es|tr|ja)/\s.* { error_page 404 mydomain.org/$1/404; } doesn't work. location ~ /(?:en|fr|de|es|tr|ja)/\s.* { return 404; } Not the behaviour I want :( Apparently I can only do a rewrite or show nginx 404? Nah I can't believe it, google uses its own template for google.com/%20 . Does anyone have an idea? I'm completely lost. -
