Choosing Flask For Large Web Application in 2017 is secure?
I've been working on Flask for few months now & I love the simplicity of it and decision making power it gives. I'm thinking to build a social networking app for mobile devices and I'll use REST API with both mysql and mongodb for backend integration. Tried flask-restful & find out pretty interesting and simple. Today I was searching for some token-based authentication resource to implement with Flask. But when I checked some of it's powerful extensions github page like Flask-oAuth & Flask-JWT, I saw huge lack of contribution. For example oAuth last commit was 5 years ago & JWT last commit was 2 years ago. Technology changing everyday & I'm working on my own & don't have a big team to keep updating everything from scratch. I know Flask isn't going anywhere near future but I'm worried about it's extensions future support should I really choose Flask for my project? on the other hand I checked Django I know Django is very powerful and it has lot's of active extensions support. But as I only need REST API so I thought Flask would be better choice. But now I'm really confused deciding which tools to choose. I'm ready to … -
Django: how to retrieve a form search parameters in a django generic listView

Django Assigning ID from Count: Avoiding Race Condition
I have a simple web app with posts and comments. For each commenter on a post I want to assign them an identifier based on the number of distinct commenters that have come before them (commenter 1, commenter 2 ect.) This is my initial attempt: comment = Comment.objects.create(**data) comment.user_identifier = comment.post.comments.distinct('author').count() + 1 comment.save() which works but leads to a race condition where if two comments are created simultaneously they have the same identifier. What's the best way to avoid this? -
How to pass a primary key from a class based view to a form?
Is there a way to get kwargs in a form? I just need the pk that has been passed to the view in my form. I tried get form kwargs with init but I wasn't able to use the pk outside of the init method. I need the pk in order to query my database and populate the form with the user's current information. I need the pk kwargs to be used where "salon_id= 18" is in the form. View.py class SalonHours(SuccessMessageMixin, LoginRequiredMixin, generic.FormView): form_class = forms.SalonHours template_name = "accounts/salon-hours.html" success_message = "Your hours have been updated!" def get_form_kwargs(self): kwargs = super(SalonHours, self).get_form_kwargs() kwargs.update({'salon': self.kwargs['pk']}) return kwargs def form_valid(self, form): monday = models.SalonHours.objects.update_or_create(day=1, salon_id=self.kwargs['pk'], defaults={'open_time': convertTime(form.cleaned_data['mondaystart'], form.cleaned_data['mondayAM']), 'close_time': convertTime(form.cleaned_data['mondayend'], form.cleaned_data['mondayPM']), 'closed': form.cleaned_data['mondayClosed']}) forms.py class SalonHours(forms.Form): def __init__(self, *args, **kwargs): self.salon = kwargs.pop('salon') super(SalonHours, self).__init__(*args, **kwargs) if models.SalonHours.objects.filter(salon_id=18).exists(): monday = models.SalonHours.objects.get(day=1, salon_id=18) mondaystart = forms.TimeField(widget = forms.TimeInput(format='%H:%M', attrs={'class': "form-control small"}), initial=convertTime(monday.open_time), required=False) mondayend = forms.TimeField(widget = forms.TimeInput(format='%H:%M', attrs={'class': "form-control small"}), initial=convertTime(monday.close_time), required=False) mondayAM = forms.ChoiceField(choices=ampm, required=True, initial=getAMPM(monday.open_time)) mondayPM = forms.ChoiceField(choices=ampm, required=True, initial=getAMPM(monday.close_time)) mondayClosed = forms.BooleanField(widget = forms.CheckboxInput(), required=False, initial=monday.closed) -
Should I test view's attributes in unit tests?
I am wondering what is a proper way to unit test a Django view, for example this one: class UserListView(LoginRequiredMixin, ListView): model = get_user_model() template_name = 'users/user_list.html' ordering = 'last_name' def get_queryset(self): self.queryset = self.model.objects.all().annotate( full_name=Concat('first_name', Value(' '), 'last_name') ) return super().get_queryset() I'm currently unit testing the get_queryset method. This gives me 100% coverage of this view, but should I also test, for example, default ordering in a unit test? Or should this be tested in an integration/system test only (e.g. using Selenium or Django's Client)? On one side, it's part of the view that influences it's behaviour, on the other side, it's used by a third party code only. -
Getting ERR_INCOMPLETE_CHUNKED_ENCODING on server when Django APIView is used
We are using Django rest_framework gunicorn Postgres Everything is working locally. But on server, when I hit request from Chrome then I got ERR_INCOMPLETE_CHUNKED_ENCODING error and when I did curl then response was curl: (18) transfer closed with outstanding read data remaining Even when I restart gunicorn then I immediately get the response for 1st request but then it hangs somewhere and further requests do not work. I am returning a blank array in response to test which is not working so response length is not the concern. In Django, I am inheriting MyView class from APIView(from rest_framework.views import APIView). When I changed APIView to View(from django.views import View) everything started working fine on server. Not sure what is causing issue? Is it APIView library or gunicorn. I tried gunicorn locally and it works. -
How I can send JSON on Django request to create a new User and Profile?

The serializer field might be named incorrectly and not match any attribute or key on the `User` instance. Original exception text was: 'User' object has no attribute 'profile'. -
Filter data from queryset in Django wihtout returning the entire queryset
I'm trying get an attribute from a given object in Djano. I'm getting the value properly but I'm curious as if there is a better way to grab this data. I'm getting the name attribute by using: owner_name = Owner.objects.filter(id=id).values('name') And it properly returns the name attribute I'm looking for, but it is in the form of: <QuerySet [{'name': u'John Doe'}]> How can I get it to just return "John Doe" instead of <QuerySet [{'name': u'John Doe'}]>? -

How do I get 'hidden' property for a div with crispy forms?
I would like my html to render with 'hidden' as a property of the div: <div class="some-class" hidden> <input id="field1"....... form stuff> </div> If my form looks like this: class SomeForm(forms.ModelForm): def __init__(self, *args, **kwargs): super(SomeForm, self).__init__(*args, **kwargs) self.helper = FormHelper() self.helper.layout = Layout( Div(Field('field1'), css_class="some-class"), ) How would I go about doing this? I can't seem to find this in the Crispy documentation. Right now I am doing it with jquery (after the page loads), and I could also add a class and then hide it in css, but how do I add the 'hidden' attribute to the div? -

Can django-impersonate be used cross-origin?
I'm attempting to use django-impersonate with my django-rest based server. The server is a pure REST server, and this is a fairly typical single-page app, so my statically-compiled JavaScript is hosted on a different server that's on another subdomain. However, it appears that django-impersonate cannot work cross-origin. Here's my understanding of what is going on: when you attempt to call the impersonate endpoint, it does a redirect. However, the standard browser behavior is that cross-origin redirections strip off the "Authorization" header. Which kind of defeats the purpose of the endpoint. Here's the error message I am getting: XMLHttpRequest cannot load http://192.168.33.10:8000/impersonate/1/. Redirect from 'http://192.168.33.10:8000/impersonate/1/' to 'http://192.168.33.10:8000/accounts/login/?next=/impersonate/1/' has been blocked by CORS policy: Request requires preflight, which is disallowed to follow cross-origin redirect. My question is whether there is any workaround for this. Since the django-impersonate package controls the endpoint, I can't manipulate the CORS headers myself, and to be honest I'm not even sure it would work if I could. -

Django - ImageField url byte string
My model contains an ImageField as below models.py class Facility(models.Model): ... image = models.ImageField(upload_to='images/facilities', default='images/placeholder.jpg') ... I have my media root and urls set to serve media files, and I can access the placeholder.jpg image by navigating to http://my.project.ip/media/images/placeholder.jpg Here is my media root settings settings.py MEDIA_URL = '/media/' MEDIA_ROOT = 'media' MEDIAFILES_DIRS = ( os.path.join(BASE_DIR, 'media/'), ) Here is my url pattern for media files urls.py url(r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT}), And finally in my template I use the ImageField url for the src attribute of my image tag list.html <img id="facil-img" src="{{ detail_facility.image.url }}" width="227" height="150"> Now when The page is loaded I get a 404 response on the request for the image. By taking a look at the html generated by my template I have found that the url in the src attribute of the image is broken: src="/media/b'images/placeholder.jpg'" Now it looks as if it is inserting the relative path as a byte string into the media url, but I have not been able to find a solution. I have tried applying a utf-8 decode to the ImageField url string, and have also attempted to cast it as a unicode string. Any suggestions would be greatly appreciated. -
