django rest framework: customize nested serializer
I have the following Django model structure: class TypeOfIngredient(models.Model): name = models.CharField(max_length=200,unique=True,null=False) slug = models.SlugField(unique=True) class Ingredient(models.Model): name = models.CharField(max_length=200,unique=True,null=False) slug = models.SlugField(unique=True) typeofingredient = models.ForeignKey(TypeOfIngredient, related_name='typeof_ingredient',null=True, blank=True,on_delete=models.PROTECT) Serializer: class IngredientListSerializer(ModelSerializer): class Meta: model = Ingredient fields = '__all__' With the above serializer i see the following api output: "results": [ { "id": 1, "name": "adrak", "slug": "adrak", "typeofingredient": null }, { "id": 2, "name": "banana", "slug": "banana", "typeofingredient": 1 }, How to get "typeofingredient": "fruit" where fruit is the name field of the typeofingredient. What i am getting is the id. I tried nested: class IngredientListSerializer(ModelSerializer): class Meta: model = Ingredient fields = '__all__' depth = 1 Then i get the api output as: "results": [ { "id": 1, "name": "adrak", "slug": "adrak", "typeofingredient": null }, { "id": 2, "name": "banana", "slug": "banana", "typeofingredient": { "id": 1, "name": "fruit", "slug": "fruit" } }, Here is showing all the details of the typeofingredient. Rather than this can i have directly "typeofingredient": "fruit" -

3-legged authorization for twitter in django
I try to make a 3-legged authorization in django with twitter, but my code doesn't work.

How to deploy django with media files?
I am trying to find a simple solution to deploy a django rest api which uses media files which are added via the admin panel. The rest api will be receiving very low traffic and so the simplest cheapest option is preferable. Currently, I am using heroku, however when I add media files through the admin panel and come back to it later the files are no longer there. Here is my settings.py: import os # Build paths inside the project like this: os.path.join(BASE_DIR, ...)

Django CreateView - Display only particular objects in foreignkey field
I have a CreateView view that has a bunch of fields that need to be filled by the user when creating a new contact. Now, I want the user to be able to see and choose only from the categories that they'd created. This is the model of Category: class Category(models.Model): class Meta: verbose_name = _('category') verbose_name_plural = _('categories') name = models.CharField(max_length=100, unique=True) profile = models.ForeignKey(Profile, on_delete=models.CASCADE) def __unicode__(self): return self.name This is the view: class ContactCreate(LoginRequiredMixin, generic.edit.CreateView): model = models.Contact success_url = reverse_lazy('site:contacts') fields = ['firstname', 'lastname', 'phone1', 'phone2', 'email', 'city', 'category'] template_name = 'site/contacts.html' context_object_name = 'all_contacts' What I need the user to see is a select that has only the categories which include the appropriat profile foreignkey associated with them. I'd be glad to get some help with this. Thank you! -

How to get inline model in post_save instance (Django Signals)?
I'm using Django (1.11.7) and Signals for some actions on the newly saved model (sending a message to the mail with the info from the model, basically). But only I add to this model one more, connected (ForeignKey) with the main (as inlines=[...] in admin.py) — it does not participate in saving the instance of the main model. My model is: # /tours/models.py class Tours(models.Model): country = models.CharField(...) ... class ToursHotels(models.Model): tour = models.ForeignKey(Tours, ...) cost = models.IntegerField(...) ... @receiver(post_save, sender=Tours) def do_something(sender, **kwargs): tour = Tours.objects.get(id=kwargs.get('instance').id) hotels = ToursHotels.objects.filter(tour_id=tour.id).order_by('cost') ... So, hotels will be empty until I edit this record again. How to do it better? Help me please. -

Django REST framework: HTML render Generic APIView

Testing with Pytest and Hypothesis
I'm required to run tests that use hypothesis as the testing strategy but I'm having problem including it in my test so I need some help. def to_svg(filename): filename='profile' SVG_DIRS = getattr(settings, 'SVG_DIRS', []) path = None if SVG_DIRS: for directory in SVG_DIRS: svg_path = os.path.join(directory, '%s.svg' % filename) if os.path.isfile(svg_path): path = svg_path else: path='/home/user/Desktop/Scripts/django1_11/myapp/'+str(filename)+'.svg' if isinstance(path, (list, tuple)): path = path[0] with open(path) as svg_file: svg = mark_safe(svg_file.read()) return svg So that's some of the code that I'm supposed to write tests for. How would I do that ? I have to open a specific file called profile.svg and return it in my function so that it loads on my webpage but hypothesis gives random strings and I need to have a specific one to open this file. I know that hypothesis isnt the way to do this but I'm required to use it. Thanks in advance. -
django way to redirect on timeout
I want to understand if the approach I've used to redirect to another page on timeout is a proper one, or if there is a more adequate way in Django. This is my template: {% extends "base.html" %} {% block content %} <h1>Thanks for visiting, come back soon!</h1> <script type="text/javascript"> setTimeout(function() { window.location.href = '/home/'; }, 2000); </script> {% endblock %} This is my urls.py: url(r"^$", views.HomePage.as_view(), name="home"), url(r"^home/$", views.HomePage.as_view()), Would it be possible to combine the two lines in one? (I'm thinking of the "Don't repeat yourself" principle) -

In above scenario, if I am using "my_method()" very frequently from django view. There will be 10000 concurrent requests accessing view from which method "my_method" is being called? is there any best way to use different class functionality in django view which give max performance and best memory management Thanks in advance. -

In django, Is it ok to write duplicate methods in different applications if method code is small?
I am working on web api using django. In this I have categorized functionality with different applications. I need suggestion for following scenario- Suppose I have three applications in a project, app1, app2 and app3 There is one function with name func(), func() require in app1 and app2 and may require in app3 in future. This function has same code, require same parameters. So, should I write func() in app1 and app2, also if require in app3. or write in only app1 and call it into app2. which is best approach for above scenario? does creating class object of class from app1 and calling method func() from another application cause performance issue if that class contains lot of code? or simply write a new method in application even though it is redundant Please suggest me best approach. Thanks in advance -
