Django CompileError: File to import not found or unreadable: bootstrap-sass/assets/stylesheets/bootstrap/variables
I am currently working on the cadasta - an open source organisation's - Django project. They require you to run their platform in a virtual machine (virtualbox) using vagrant. As I enter their repository, and run their server using ./runserver, I am all of a sudden getting a CompileError which says: File to import not found or unreadable: bootstrap-sass/assets/stylesheets/bootstrap/variables. Parent style sheet: /vagrant/cadasta/core/static/css/_variables.scss. on line 74 of core/static/css/_variables.scss @import "bootstrap-sass/assets/stylesheets/bootstrap/variables"; Following this link: https://github.com/jrief/djangocms-cascade/issues/130, I found that libsass is already installed, and so I tried installing bootstrap-sass inside the VM, but it did no good. Everything was working fine until I renamed the cadasta-platform directory (i.e their github repo that I cloned, and so the main project is included inside this folder only.) and refreshed. I even tried running the server again, but couldn't get through this error. I suppose renaming the directory shouldn't be the cause? Please help. -
Django: create file and download with return results in the same html
I am stuck in a Django process and would like to seek your help. Specifically, I create a function of clicking a button to generate a report from the database in views.py. Then the report will be downloaded. Further to that, I want the html return the download completed message after the work is done.

I attach the code as below for your reference.

DRF Posting Foreign Key UserId
I am using the django rest framework and I have a very simple model of Posts for a particular user which I have serialised in the following manner. Serializers.py class PostSerializer(serializers.HyperlinkedModelSerializer): image = serializers.ImageField(max_length=None, use_url=True) question = serializers.CharField(required=False) ayes = serializers.CharField(required=False) nays = serializers.CharField(required=False) neutrals = serializers.CharField(required=False) class Meta: model = Posts fields = ('user','question', 'image','ayes', 'nays', 'neutrals') My models.py is as follows class Posts(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) created = models.DateTimeField(auto_now_add=True) question = models.TextField(max_length=500, blank=True) image = models.ImageField('optionalImage', upload_to='images/posts/', default='/images/posts/blank.png') ayes = models.TextField(max_length=200, default=0) nays = models.TextField(max_length=200, default=0) neutrals = models.TextField(max_length=200, default=0) When I tried posting to this I kept getting NOT NULL Integrity constraint error of user_id.

DjangoRest - It is possible to define multiple create(self, request) in ModelViewSet
I have a project which need to perform different create processes in the same Model. We can achieved this one by creating multiple ModelViewSet. class AnimalViewSet(viewsets.ModelViewSet): queryset = Animal.objects.all() serializer_class = AnimalSerializer def create(self, request): # just simply create the object... pass Endpoint is POST /api/animal/ class CalvingViewSet(viewsets.ModelViewSet): # This is called when an animal has successfully delivered its new born.. queryset = Animal.objects.all() serializer_class = AnimalSerializer def create(self, request): # create the object.. # define parent animals pregnancy as success # and more.. pass Endpoint is POST /api/calving/ But i prefer not doing so. Now it is possible to define multiple create(self, request) in a single ModelViewSet? class AnimalViewSet(viewsets.ModelViewSet): queryset = Animal.objects.all() serializer_class = AnimalSerializer def create(self, request): # just simply create the object... pass def calving(self, request): # create the object.. # define parent animals pregnancy as success # and more.. pass Endpoint for create(self, request): is POST /api/animal/ the is problem is i don't have any idea about the endpoint of calving(self, request): I also found @list_route(methods=['post']) may help but i want to make sure there is another right way to do this. -
How do I correctly serve static files with django+nginx in separate docker containers?

Should I use slug field too in django
I am developing an blog like application where there are going to be posts with similar or sometimes same titles. Also users are able to edit the titles of their post whenever they want. Currently my urls look like this. <a href="{% url 'myapp:read' post.id %}">{{post.title}} </a> Now I've read few answers where along with id they have passed slug too like url of this question. Even with id the url is going to be unique, right? then why slug? and if it is for humanizing the url then should be store it too? So to summarize: If id is unique then why slug? If its important then should we store it? If it has anything to do with canonical-link please elaborate the working of canonical links & how slug can help it? or at least direct me to the source. Reference: when to store slugfield in database in django? and this answer Thanks in advance. -

I have a Django url for users to change their password, which looks like this: url(r'^change-password$', views.user_change_password, name='change_password'), url(r'^change-password/done/$', views.user_changed_password, name='password_changed') Where views.user_change_password is: def user_change_password(request): response = password_change(request, template_name=r"Foo/Account/change_password.html", post_change_redirect=reverse('Foo:password_changed')) return response This works, but it seems to me that having to specify the lookup name password_changed in two separate places violates the principle of DRY. Is there a standard way in Django of dealing with this? -
couldn't import django in virtualenv but works when deactivated
I am trying to deploy my Django Projects on Amazon AWS using Ubuntu 16.04. I am running python version 2.7.12 and Django 1.10.5. I created my virtualenv named venv and then activated it. I get this error when I try to run python manage.py runserver. Traceback (most recent call last): File "manage.py", line 17, in "Couldn't import Django. Are you sure it's installed and " ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment? Then I realize Django might not be in my python path. So I added export PYTHONPATH="/usr/local/lib/python2.7/dist-packages/django" into my venv/bin/activate script. Now with the virtualenv activated I can go into python and type import sys sys.path ['', '/usr/local/lib/python2.7/dist-packages/django', '/home/ubuntu/TravelBuddy/venv/lib/python2.7', '/home/ubuntu/TravelBuddy/venv/lib/python2.7/plat-x86_64-linux-gnu', '/home/ubuntu/TravelBuddy/venv/lib/python2.7/lib-tk', '/home/ubuntu/TravelBuddy/venv/lib/python2.7/lib-old', '/home/ubuntu/TravelBuddy/venv/lib/python2.7/lib-dynload', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/home/ubuntu/TravelBuddy/venv/local/lib/python2.7/site-packages', '/home/ubuntu/TravelBuddy/venv/lib/python2.7/site-packages'] As you can see now django is indeed in my python path. I thought this was going to fix the problem but it didn't: it still says couldn't import Django. Now I am confused because when I deactivate my virtualenv and import Django it does work. this is what prints out when I deactivate my virtualenv and do sys.path ['', '/usr/local/lib/python2.7/dist-packages/django', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', … -
How to remove {'field__avg': when printing avg in Django templates
This should be a pretty simple question, but googling for it has been difficult. I'm trying to average a field in Django, and I've got that all figured out, but when I print it in my template, I get this annoying "{'field__avg':" printing along with the actual value. How do I remove that and only print the actual value? Alternatively, how do I call that value so that I can use it in some logic? -
PicklingError when trying to access user ID in Django form
This is a strange one. In a Django-based web application I've made, users chat in a public room, or can create private rooms with friends. All unseen messages aggregate in a separate section called unseen activity. When cleaning the submitted data for UnseenActivityForm, I need to run some validation for the specific user as well (thus I need the user_id in my form). To do this, I pass it like so (via a function-based view): if request.method == 'POST': form = UnseenActivityForm(request.POST,request=request) And in the form, I included: class UnseenActivityForm(forms.Form): comment = forms.CharField(max_length=250) group_reply = forms.CharField(max_length=500) class Meta: fields = ("comment", "group_reply", ) def __init__(self,*args,**kwargs): self.request = kwargs.pop('request', None) super(UnseenActivityForm, self).__init__(*args, **kwargs) Later while cleaning data, I do: def clean_comment(self): comment = self.cleaned_data.get("comment") if not can_reply(comment,self.request.user.id): raise forms.ValidationError('tip: write something different') return comment My problem is I get Can't pickle <type 'function'>: attribute lookup __builtin__.function failed if I try to submit a comment in the aforementioned setup. Highly peculiarly, I don't get this error if I remove request=request from my view, i.e. if I do: if request.method == 'POST': form = UnseenActivityForm(request.POST) But then of course, I can't access self.request.user.id for form validation. Why is this error happening, and what … -
model design for moving device to label
I am trying to add gmail feature of moving the mail to custom created label or already made label. It is a move to label feature. When you select the mail and then click on move to label actions, you will see lots of pre-defined label name such as important, sms, personal, work etc and also a create a new label in the dropdown. For having such feature, have i missed something important here ? Here is my model class Device(BaseDevice): """ This stores Device """ # Description is optional (can be blank, can be null) description = models.TextField(blank=True, null=True) created_on = models.DateTimeField(auto_now_add=True) updated_on= models.DateTimeField(auto_now=True) def __str__(self): return self.name class Label(models.Model): """ This creates a label """ # Name is required name = models.CharField(max_length=250, blank=False, null=False) device = models.ForeignKey(Device, related_name='label') -
Query Django ParentalKey of ForeignKey
I have a SectionMeta model that has ParentalKey relationship to a Section model that has a ForeignKey relationship to my Product model. The way it works is we have multiple sections of a menu, I.e. salads, pizza, pastas etc... and each section as meta data that can go with it, I.e "Add $3 for chicken, 2 for etc.." and that Section is a Foreign Key to the Product itself. I would have placed the SectionMeta as part of the Section, but the Section could belong to multiple menus I.e. Lunch, Dinner, Special etc... This isn't important, but I needed to mention it because it would have been the obvious thing to do. I need to print the SectionMeta on my template if one exists. This is the target template output Salads (FK-Section)(add chicken $3) <=SectionMeta Cobb (product.name) Ceasar (product.name) Pizza (FK-Section)(1/2 off during lunch) <=SectionMeta Supreme (product.name) Veggie (product.name) ... Section Model @register_snippet class Section(ClusterableModel): name = models.CharField(max_length=255, verbose_name='Section') panels = [ MultiFieldPanel( [ InlinePanel('section_meta', label='Section Meta'), ], heading='Section Meta', classname='collapsible' ), ] ...
