behave-django: When running multiple apps' features the 2nd app does not find it's steps
I'm using behave 1.2.5 on Django 1.11 with behave-django 1.1.0. My historic folder structure is as following: projectroot/some/folder/app1/features/feature1.py projectroot/some/folder/app1/features/steps/steps.py projectroot/some/folder/app1/features/steps/steps_additional.py projectroot/some/folder/app2/features/feature2.py projectroot/some/folder/app2/features/steps/steps.py When I run the tests for app1 and then for app2, everything is fine. If I run them together, app1 passes and app2 complains that the step definitions are missing. Is my project structure not compatible with behave? I'm a bit lost at the moment. -
Django conditional create
Does the django ORM provide a way to conditionally create an object? For example, let's say you want to use some sort of optimistic concurrency control for inserting new objects. At a certain point, you know the latest object to be inserted in that table, and you want to only create a new object only if no new objects have been inserted since then. If it's an update, you could filter based on a revision number: updated = Account.objects.filter( id=self.id, version=self.version, ).update( balance=balance + amount, version=self.version + 1, ) However, I can't find any documented way to provide conditions for a create or save() call. I'm looking for something that will apply these conditions at the SQL query level, so as to avoid "read-modify-write" problems. -
Django Admin template override
I am following the tutorial on django website to create my first django app. Now I am stuck trying to override Django Admin template. My project directory is this: First I tried creating a new admin template in the surveys app. It works. Then, I tried with the override function. For this I created at surveys/admin.py the following code: from django.contrib.admin import AdminSite from django.utils.translation import ugettext_lazy class SurveysAdminSite(AdminSite): site_header = ugettext_lazy('Test administration') surveys_admin_site = SurveysAdminSite() And add to computationalMarketing/urls.py the following: from .admin import surveys_admin_site urlpatterns = [ path('admin/', surveys_admin_site.urls, name='admin'), ] It doesn't work, so I search, and tried something different. Add this same previous code to surveys/urls.py. Neither works. Then I rollback the changes to save the code to computationalMarketing/urls.py, but this time I changed the code from surveys/admin.py to computationalMarketing/admin.py (in fact I created the file because it doesn't exists. It works and now I see the site header that I want, but I get You don't have permission to edit anything. I have seen that is something related with superuser creation, but until now I was able to admin my surveys app without problem, so I believe in some solution related with override properly the … -

Prevent create/update foreign key to forbidden objects in Django rest framework
Let us assume I have the following models class Blog(models.Model): user = models.ForeignKey(User, null=False, on_delete=models.CASCADE) class Post(models.Model): blog = models.ForeignKey(Blog, null=False, on_delete=models.CASCADE) post = models.TextField() The problem is that creating a Post will let me set the blog id to anything (that exists). That means that I am able to create a Post object that has a relation to a Blog object that the user does not "own". However, there are easy and documented ways to prevent the user from accessing objects via the GET method, that are forbidden to them, by filtering the queryset and using check_object_permissions. Example: class PostViewSet(viewsets.ModelViewSet): serializer = PostSerializer def get_queryset(self): return Post.objects.filter(blog__user=self.request.user) def check_object_permissions(self, request, obj): if obj.user != request.user: raise exceptions.PermissionDenied() super().check_object_permissions(request, obj) How do I solve my above issue and prevent creating relations to forbidden objects the smartest/correct way in Django REST framework? -
Parse large file and paginate / load its parts with scrolling
I'm looking for suggestions and the most Django way of loading large variable content (say massive 10,000 lines list) part by part to user page to display only some lines before user asks for more. This is a detailed scenario (I hope it makes sense to you. It is just a simple example to help dealing with large template variables and pagination): User goes to website.com/searchfiles which is hosted on my Django backend and returned as a template searchfiles.html template contains one form with Select drop-down menu to let choose a file that already exists on server (say there are 20 massive log files). Below the drop-down menu there is a text box that allows user to enter a regular expression string. So only two items in the form. P.S. Each file is usually pretty big e.g. 20-30MB When user selects the file and enters regular expression in the text box and clicks on "Submit", HTTP POST is made Django backend receives POST, reads the filename + regexp string and executes function dosearch(FILE, pattern) dosearch function does something like this: dosearch(FILE, pattern): result = [] fh = open(FILE, 'r') for line in fh: if re.match(pattern, line): result.append(line) return result Now, … -
Translation label with link dosen't work

Django form field creation and form data retrieval
I have a model in django as follows: class DeviceType(models.Model): device_type = models.CharField(max_length=200,unique=True) def __str__(self): return self.device_type class Device(models.Model): device_type = models.ForeignKey(DeviceType,to_field='device_type') serial_number = models.CharField(max_length=200,unique=True) in_use_by = models.ForeignKey(User,to_field='username') brand = models.CharField(max_length=200,default="-", null=False) model = models.CharField(max_length=200,default="-", null=False) type_number = models.CharField(max_length=200,blank=True,null=True) mac_address = models.CharField(max_length=200,blank=True,null=True) I want to make a django form that would have a drop-down as follows: (Below is the general pattern of the data present in drop-down menu): devicetype-serialnumber-model-brand e.g: Laptop-abcd1234-T45k-QWER How can I achieve this? My, second question is, Suppose I select the relevant option from drop-down, fill the other data required in the form and click submit. How can I store the data coming from the dropdown present in the form into their respective field in Device Model? My third question is, how can i print only that data in the dropdown that belongs to a particular user? For e.g: If I have only two devices with me then, the for dropdown should display only options for that two devices. -

Django http-request in graphene schema
How do I get the http-request-session object into a graphene schema? I have stored som values in request session that I need access thru. A possible solution is to send the session-id to the frontend and then pass it into the post request, but that does not seem like a good solution. Graphene hast a context_value but I don't understand how I works. Into my Django-views I put this: schema = graphene.Schema() schema.execute('{ viewer }', context_value={'session': request.session}) In my graphene schema if I try to do like described in the tutorial, it says 'WSGIRequest' object has no attribute 'get' class Query(graphene.ObjectType): viewer = graphene.Field(Viewer) def resolve_viewer(self, info): info.context.get('session') print(info.context.session.keys()) #an empty array return Viewer() -

Django Summernote WYSIWYG editor jquery edit
I'm trying to use Summernote editor with Django. There is a fix i need to implement- to strip any copy-pasted text of all tags and there is a fine solution here which looks like this: $('.summernote').summernote({ callbacks: { onPaste: function (e) { var bufferText = ((e.originalEvent || e).clipboardData || window.clipboardData).getData('Text'); e.preventDefault(); // Firefox fix setTimeout(function () { document.execCommand('insertText', false, bufferText); }, 10); } } }); My problem is that i don't know how to implement this in a django template since i'm using django-summernote (link) andcrispy-forms- i have never worked with jquery. My cyrispy-forms template wraps the Summernote widget in a div with id = div_id_text - Is there any way to point the code above to this ? I tried including this in my html template but to no avail: <script > $('#div_id_text').on('summernote.paste', function(e) { var bufferText = ((e.originalEvent || e).clipboardData || window.clipboardData).getData('Text'); e.preventDefault(); // Firefox fix setTimeout(function () { document.execCommand('insertText', false, bufferText); }, 10); } ) </script> -
Django: Combine 3 separate 'filters()' into single query
I have following piece of code def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) prefetch = ['vendor', 'picture'] context['most_popular_products'] = Product.objects.filter(is_popular=True)[:5].prefetch_related(*prefetch) context['coming_soon_products'] = Product.objects.filter(is_coming_soon=True)[:5].prefetch_related(*prefetch) context['recent_products'] = Product.objects.all()[:5].prefetch_related(*prefetch) return context As you see there are 3 separate calls for 5 latest most_popular, coming_soon and recent products. It there a way to reduce number of database calls? I'd like to construct single query like, popular, coming_soon, recent = Product.objects.filter...and.so.on Any ideas? thanks
