Django form.save() saves incorrect data
I have a weird problem. My form doesn't save recieved data for one field. There is a field category which is a ForeignKey, in form it is ModelChoiceField filed. You can choose from 4 categories - Uncategorized, Televisions etc. The problem is that even when I choose Televisions or something else, it saves the model with category Uncategorized instead of Televisions. When I print request.POST it sends correct data. <QueryDict: {u'category': [u'3'], u'csrfmiddlewaretoken': ['token'], u'name': [u'dsadasda'], u'groups': [u'5']}> FORM class NewProductForm(forms.ModelForm): class Meta: model = models.Product fields = ('name','category','groups') def __init__(self, user, *args, **kwargs): super(NewProductForm, self).__init__(*args, **kwargs) self.fields['groups'] = forms.ModelMultipleChoiceField( queryset=models.Group.objects.filter(user=user)) self.instance.user = user MODEL class Product(models.Model): user = models.ForeignKey(User,null=False,blank=False) name = models.CharField(max_length=200) groups = models.ManyToManyField('Group', related_name='products') category = models.ForeignKey('Category', related_name='products', null=True, blank=True) VIEW @decorators.is_authenticated_or_homepage def add_new_product(request): form = NewProductForm(request.user, request.POST or None) if request.method == 'POST': print request.POST if form.is_valid(): form.save() return HttpResponseRedirect(reverse('dashboard_products')) context = {'form':form} return render(request,'main_app/dashboard/new-product.html',context=context) Do you know what's the problem? -
How to assertRaises a django.contrib.auth.models.DoesNotExist exception?
I'm trying to assert in a test that a statement raises this exception however it appears that it is impossible to import said exception. This does not work for example: from rest_framework.test import APITestCase from rest_framework.test import APIRequestFactory from CarPooling.views import login, logout from django.urls import reverse from django.contrib.auth.models import User, UserManager from django.contrib.auth import authenticate from rest_framework.authtoken.models import Token from CarPooling.models import AccountActivationToken from rest_framework import status from django.contrib.auth.models import DoesNotExist class LoginViewTests(APITestCase): def test_login(self): url = '/api/token/' data = {'email': 'up20@fe.up.pt', 'password': 'testpassword'} user = create_user('joao', 'testpassword', 'up20@fe.up.pt') user = User.objects.get() user.is_active = True user.save() response = self.client.post(url, data, format='json') self.assertEqual(response.status_code, status.HTTP_200_OK) self.assertEqual(response.data['token'], Token.objects.get(user=user).key) data = {'email': 'up20@fe.up.pt', 'password': 'tsubasaolivesr'} response = self.client.post(url, data, format='json') self.assertEqual(response.status_code, status.HTTP_400_BAD_REQUEST) data = {'email': 'up20@fe.up.pt', 'password': 'tsubasaolivesr'} self.assertRaises(models.DoesNotExist, self.client.post(url, data, format='json')) The test fails complaining that exception django.auth.contrib.auth.models.DoesNotExist was invoked, even though I explicitly am asserting it is supposed to happen. -
django.db.utils.OperationalError: 1005, 'Can't create table `xyz`.`#sql-600_237` (errno: 150 "Foreign key constraint is incorrectly formed")
I am trying to add One-to-One keys into my Django app, but I always get that error when I try to "migrate" process (makemigrations works like charm).

But if that error message appears during "migrate", that should not be something good happening. If there's no problem, it is possible to skip that last step which crash my migration ? Can someone can say me why do I get that error message and how I can resolve it ? Thank you very much and have a great day ! -

Include template with dynamic Django form
I have a model with a choices field, and the creation form has different fields depending on the field. I'm implementing the design of a dashboard in which the user can click a button (one button for each choice) and a modal containing the model form will be displayed. I want to use a template only for the modal, and send the form and action URL to it depending on which button the user clicks, but that would mean I have to mix JS and Django variables and I don't know if that's a good idea. The code right now is something like this: dashboard.html <div class="add-connections"> <div class="col-sm-3 text-center" > <div class="connection-box"> {% if user_connections.EP %} <img src="{% static 'images/green-check-mark.png' %}" alt="Connection added" class="check"> {% else %} <a href="" class="btn" data-toggle="modal" data-target="#modal-new-connection">Activate</a> {% endif %} </div> </div> <div class="col-sm-3 text-center" > <div class="connection-box"> {% if user_connections.OLX %} <img src="{% static 'images/green-check-mark.png' %}" alt="Connection added" class="check"> {% else %} <a href="" class="btn" data-toggle="modal" data-target="#modal-new-connection">Activate</a> {% endif %} </div> </div> <div class="col-sm-3 text-center" > <div class="connection-box"> {% if user_connections.CC %} <img src="{% static 'images/green-check-mark.png' %}" alt="Connection added" class="check"> {% else %} <a href="" class="btn" data-toggle="modal" data-target="#modal-new-connection">Activate</a> {% endif %} </div> </div> … -
Django Apache installation on CentOS. Using Apache as the Web server
from this link Serving files Django doesn’t serve files itself; it leaves that job to whichever Web server you choose. We recommend using a separate Web server – i.e., one that’s not also running Django – for serving media. Here are some good choices: Nginx A stripped-down version of Apache If, however, you have no option but to serve media files on the same Apache VirtualHost as Django, you can set up Apache to serve some URLs as static media, and others using the mod_wsgi interface to Django. after the painful installation of django, why can't I use apache to serve the application? Edit: using virtualenv for python -
Django page not rendering html template
New to Django - I am working on a simple deployment of a Django web application using the DjangoGirls tutorial and having issues with rendering templates from HTML. The code below runs on my localhost perfectly (displaying the posts from my blog model), the environment that is set up on the server is identical and the error log is empty on pythonanywhere, nothing in the console to assist. <html> <head> <title>Michael Test</title> </head> <body> <p>Hi There!</p> <p>It works!</p> {% for post in posts %} <div> <p>published: {{ post.published.date }}</p> <h1><a href="">{{ post.title }}</a></h1> <p>{{ post.text|linebreaksbr }}</p> </div> {% endfor %} </body> </html> http://michaelbergin.pythonanywhere.com/ - is the site where the deployment is not functioning properly (only showing Hi there!, It works!) and not rendering from the template. Thanks for any tips. -
Django core serializers, full path of image or method serialize

Django - How to pass queryset to the template using a class based UpdateView?

Django 1.8 : Model Admin Form - Checkbox make one-to-one form appears and set ID
I am currently maintaining a NPO org management system that works only with Django Admin (it is a database for members, volunteers, activities etc..) Now they want to add a functionality : You have a model admin form "Person", with name, address, phone etc.. But lower in that form, it should have a checkbox that when clicked, it spoils a form for a one-to-one entity. If the checkbox is not clicked then the one-to-one is NULL. When you reload this form after saving, what you should see is : If the checkbox was clicked and sub form entered, the checkbox should be already clicked, and the form present. It is possible to do that kind of functionality with Django 1.8 ? If yes, do you have some links to recommend me ? Hints ? Thank you very much and have a great day ! -
complex annotation in django query

I wanted it for template, where I want to do for loop with stats {% for foo in stats %} <h2>{{ foo.name }} </h2> {{foo.count}}/{{foo.max}} sum … -
Can not compare text with redis hash key in Django
This problem bugs me for hours. Basically I'd like to compare unicode text retrived from mysql database and hash map keys in redis. Here is the code in my views.py: topicslug = topic.slug.encode('unicode-escape') topictitle = topic.title.encode('unicode-escape') topic_link = '<a href="/topic/%s">%s</a>' %(topicslug, topictitle) topic_link = "\'" + topic_link + "\'" print 'topic_link is', topic_link key_exists = r.hexists(creator_key, topic_link ) if key_exists == 1: print 'alert key found' print 'hget', r.hget(creator_key, topic_link) r.hdel(creator_key, topic_link) print 'alert key deleted' else: print 'alert key not found' print 'hmgetall', r.hgetall(creator_key) And here is the result of prints that I get: topic_link is '<a href="/topic/\u0631\u062f\u06cc\u0633-\u062a\u0633\u062a">\u0631\u062f\u06cc\u0633 \u062a\u0633\u062a</a>' alert key not found hmgetall {'<a href="/topic/\xd8\xb1\xd8\xaf\xdb\x8c\xd8\xb3-\xd8\xaa\xd8\xb3\xd8\xaa">\xd8\xb1\xd8\xaf\xdb\x8c\xd8\xb3 \xd8\xaa\xd8\xb3\xd8\xaa</a>': '1'} As you can see, since the `topic_link' that I construct is in unicode but the key obtained from redis is in hex (i guess), so the do not match. I'm wondering how can I fix this so that the comparison can be performed? -

How to create a table with links to change boolean values of a model instance in Django?
I have a ListView where I show customer orders in multiple tables. There is one table for orders that are sent (not yet marked as 'received'), one table for 'received' orders, one for 'processed' order and one for 'delivered' orders. This list is a staff list, only certain users have access to it. What I would like to do is to add a button (link or maybe a submit button for a form) to each order row. For example, in the table for the sent orders (not yet 'received') there should be a button that says 'Mark as received' ('Kvittera' in Swedish), in the 'received' table, the button should say 'Mark as processed' ('Klar' in Swedish) and so forth. This is a picture of how I would like it to look (sorry for the Swedish): The model has three boolean fields; order_received, order_processed and order_delivered. If I were to push the button 'Kvittera' in the table, the boolean value of order_received should change from False to True, and so forth. Note that you should never be able to change it back to False. I can set up a button/link that GETs a URL, i.e. http://example.com/orders/1/receive which runs a view that … -
