Django translations not working on elastic beanstalk aws
Django translations work on my local machine but when I deploy the application to elastic beanstalk AWS the translations are not found by the server. It seems to be a path related issue but I am unable to figure out what is wrong with the path that I am using. I have the following code in my settings file. here = lambda *x: join(abspath(dirname(__file__)), *x) PROJECT_ROOT = here('..') root = lambda *x: abspath(join(abspath(PROJECT_ROOT), *x)) LOCALE_PATHS = ( root('conf', 'locale'), ) My settings file is inside the main app and the conf folder is in the main project directory which is one directory level above the settings file. -
How to choose by which fields will be filtering?
How can I can exclude(pop) email field from data object in my view in order to make filtering by the remaining data? View's logic will be based on email later. Also, It's possible that I'll need to exlude more fields from serializer... I've got simple view like this: class DataView(GenericsAPIView): serializer = TotalSerializer def post(self, request, *args, **kwargs): data = DataSerializer(data=request.data) data.is_valid(raise_exception=True) # Here I need to pop some fields from serializer queryset = self.get_queryset(**data.validate_data) ... serializer = self.get_serializer(queryset, many=True) return Response(serializer.data) And here is my serializer, which serializes the data from the post request: class DataSerializer(serializers.Serializer): field_one = serializers.CharField(max_length=255) fields_two = serializers.CharField(max_length=255) email = serializer.EmailField() -

Create function in database using django ORM
In my project I want to get people who have birthday between some days, I hope to find a solution which does not force any limitations to queries. I have found this solution which seems efficient and suite for my problem. But now I have a second problem to create the function in database using django ORM, because this must be portable and works with test database also. I could not find any proper way to able to define the function and the index based on it in django. In brief I want to create below function in database using django: CREATE OR REPLACE FUNCTION indexable_month_day(date) RETURNS TEXT as $BODY$ SELECT to_char($1, 'MM-DD'); $BODY$ language 'sql' IMMUTABLE STRICT; CREATE INDEX person_birthday_idx ON people (indexable_month_day(dob)); -

Using related_name to call objects attributes in django templates
I have 3 models. User, Post and Proof. Posts are added by a User to the website. When other users do what the post says. They upload 2 images to say they did the task. The template will show the 2 images they uploaded. I know I am making some mistake in the template calling the images. Does anyone know the correct way to use related_name to call for the images. FYI I am new to python and Django I am sorry if this question is too trivial or has wrong logic models/posts.py User = get_user_model() class Proof(models.Model): user = models.ForeignKey(User, related_name='proofmade') post = models.ForeignKey(Post, related_name='proofmade') made_at = models.DateTimeField(auto_now=True) image_of_task= models.ImageField() proof_you_made_it = models.ImageField() suggestions = models.TextField(max_length=1000) def __str__(self): return self.post.title Templates {% for user in post.made.all %} <div class="container"> <img src="{{ user.proofmade.image_of_task.url }}" height="150px"/> <img src="{{ user.proofmade.proof_you_made_it.url }}" height="150px"/> </div> {% endfor %} -
Makemigration Keeps generating new migrations files without any changes
I am running django 1.11.11 , python3.5 I have two models in my first_app: class Component(models.Model): created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) code = models.CharField(max_length=15) title = models.CharField(max_length=255) slug = models.SlugField() institution = models.CharField(max_length=255) sub_components = models.ManyToManyField('SubComponent',blank=True) @property def program(self): return self.program_set.all().first() class SubComponent(models.Model): CURRENCIES = [("US","USD"),("EU","Euro"),("CAN","$ CAN"),] code = models.CharField(max_length=15) title = models.CharField(max_length=255) slug = models.SlugField() fee = models.FloatField() currency = models.CharField(choices=CURRENCIES,max_length=3,default="US") @property def component(self): return self.component_set.all().first() Those 2 models are my issue. The same app has the following models as well: Program(models.Model): components = models.ManyToManyField(Component,blank=True) Procurement(models.Model): sub_component = models.ForeignKey(SubComponent,blank=True,null=True) An other app called second_app: It has ForeignKey/ManyToManyField to those models above. Evertytime I run makemigrations, it generates new migrations files, even though I didn't make any change to those two models Component and SubComponent.

How to make a real time notification from local server with Django Rest API to android application
I'm developing an android application using Android Studio and the server side for this application using Django and Djangorestframework. Inside the application, there's one fragment that will retrieve some data (for example, in this case, we call it "smart bin data") and it will show as listview (in a fragment), but with some conditions: Each of smart bin data has a field (let's say a flag). The default flag is 0. When this flag changed to 1, I want there's a real-time notification show up in the application and when the notification is clicked, it will open the listview as I mentioned above (that show the specific smart bin data). Listview is used because the smart bin data is more than one, each belongs to specific users. For example, if the flag of user 1 and user 2 changed at the same time, there will be 2 notification and 2 row/lists will be presented in the listview for each user. In the listview, you can delete each of the smart bin data via a button. When the button is clicked, it will delete the row/list of the data and send an order to change the flag of the data back … -
Django append objects if count less
I'm using Django 2.0 I'm writing a quiz application and I have to build 4 options for each question. options = ChapterQuestion.objects.filter( chapter__course=course_learn.course ).exclude( pk=question.pk ).order_by('?').all()[:3] This will query for other questions excluding current question to ask. But sometimes it might return less than 4 options in case total questions in the database is is less than 4. In that case I want to repeat same set of options to build 4 options. How can I repeat the same objects to build 4 options?
