I know that this is an old thread but I’ve just bumped into the same issue and I don’t think that this is caused by a missing package. As the Django core distribution contains the correct wsgi handler already. The problem here is that when wsgi.py is executed it’s missing the packages of the site-packages … Read more
You’ll want to loop through the tag_list and apply a filter for each one. tag_list = [‘tag1’, ‘tag2’, ‘tag3’] base_qs = Design.objects.all() for t in tag_list: base_qs = base_qs.filter(tags__tag__contains=t) This will give you results matching all tags, as your example indicated with and. If in fact you needed or instead, you will probably need Q … Read more
Here’s what I did when I got the same error from Django Rest Framework while sending an API request from Restangular. What this does is add CORS (Cross-Origin Resource Sharing) headers to responses from Django Rest Framework. Not having CORS headers was the cause of the error. In the Django Project root folder (where the … Read more
This is how I set up celery with django on elastic beanstalk with scalability working fine. Please keep in mind that ‘leader_only’ option for container_commands works only on environment rebuild or deployment of the App. If service works long enough, leader node may be removed by Elastic Beanstalk. To deal with that, you may have … Read more
I think you’re probably using the admin’s bulk delete feature, and are running into the fact that the admin’s bulk delete method doesn’t call delete() (see the related ticket). I’ve got round this in the past by writing a custom admin action for deleting models. If you’re not using the admin’s bulk delete method (e.g. … Read more
If you can’t use a third-party app and want to add a class (e.g., “form-control”) to every field in a form in a DRY manner, you can do so in the form class __init__() method like so: class ExampleForm(forms.Form): # Your declared form fields here … def __init__(self, *args, **kwargs): super(ExampleForm, self).__init__(*args, **kwargs) for visible … Read more
I think you might need to approach this in a slightly different way – by modifying the ModelForm, rather than the admin class. Something like this: class OrderForm(forms.ModelForm): def __init__(self, *args, **kwargs): super(OrderForm, self).__init__(*args, **kwargs) self.fields[‘parent_order’].queryset = Order.objects.filter( child_orders__ordernumber__exact=self.instance.pk) class OrderAdmin(admin.ModelAdmin): form = OrderForm
When you are using SessionAuthentication, you are using Django’s authentication which usually requires CSRF to be checked. Django REST Framework enforces this, only for SessionAuthentication, so you must pass the CSRF token in the X-CSRFToken header. The Django documentation provides more information on retrieving the CSRF token using jQuery and sending it in requests. The … Read more
__unicode__ does do that. Your model should look something like this: class SomeModel(models.Model): def __unicode__(self): return ‘Policy: ‘ + self.name On Python 3 you need to use __str__: def __str__(self): return ‘Policy: ‘ + self.name
I realize this question is old and at the time the best option for Data Migrations was using South. Now Django has its own migrate command, and the process is slightly different. I’ve added these models to an app called books — adjust accordingly if that’s not your case. First, add the field to Book … Read more
