How to create a custom signal in django?
I have been searching for a guide to write my own custom signals in django. Django documentation does a good job of giving details of individual topic, but does not give a working example of the same, and I can't seem to understand how to write my own custom signals. I searched online on various sites but it still does not ring any bells :P. Can anyone give a complete working example of the same? Thanks in advance. Regards. -
Django+Django-REST+AngularJS or maybe just AngularJS?
I pretty much a beginner and I am tasked to translate an Excel tool to a web based program. So pretty soon I favored Python since I think it's easy to use and is used extensively for calculations of all sorts. So I looked into the Django. Now I also needed to show graphs. "Coding for entrepreneurs" advised to use the Django-REST framework for this, so I looked into that also. Now I made a very limited functionality REST API. I.e. still very possible to trash this and go into a different direction... My thinking here is to detach the backbone (REST API) which solely deals with the bare bone information. And next I would like to connect this to a nice user interface. So I am now starting to look into AngularJS. Now AngularJS seems to be much more than a shiney front, and again has quitte the learning curve to master it. So it has been quitte a journey, I feel like I pull a string and just get more string. I am now wondering if it's just possible to write the whole applications using just AngularJS? Or am I on a viable and doable path devising a … -
Use Pillow resize with an ImageField
I am new to python and trying to use ImageField in my model. I have some images in files separate from my Django Project that I want to upload. So I have a Django model class Product(models.Model): img_thumbnail = models.ImageField(upload_to='products_images', blank=True, null=True) In my conversion code which uploads images, I want to generate thumbnails at a specific height so I can not use: img = Image.open(file_path) img.thumbnail() Instead, I calculate the necessary width and resize it using Pillow. img = Image.open(file_path) h_percent = (75/ float(img.size[1])) if h_percent < 1: width = int((float(img.size[0]) * float(h_percent))) img = img.resize((width, base_height), Image.ANTIALIAS) filename = os.path.basename(file_path) That works fine but when I tried to save that to an ImageField, I get an error: AttributeError: 'JpegImageFile' object has no attribute 'content' product.img_thumbnail.save(filename, img, True) Searching the web, I found reference to SimpleUploadedFile. So write the resized image with a suffix. I received another error; : 'charmap' codec can't decode byte 0x81 in position 251: character maps to file_root, file_ext = os.path.splitext(file_path) new_file_name = file_root + '_thumbnail' + file_ext img.save(new_file_name) filename = os.path.basename(file_path) with open(new_file_name) as infile: _file = SimpleUploadedFile(filename, infile.read()) So what should I do here? I am using Python 3.6 with Django 2.0 Thanks … -
How to serialize in Django Rest Framework with custom fields?
Let's say my model is: class Contact(models.Model): email = models.CharField(max_length=50) I want to have a serializer that receives multiple fields and then combine them to create an email. For example: class ContactSerializer(serializers.Serializer): first = serializers.CharField() second = serializers.CharField() third = serializers.CharField() It would convert {"first": "user", "second": "example", "third": "org"} to a new Contact object with the email 'user@example.org'. What should I do? -
Django: Rendering a table with 2 objects of variable size in HTML template
I've a bit of a dilemma here, and I'm not sure how best to approach it. I need to create a table of all objects in model "Chamber" and all objects in (ForeignKey related) model "ChamberProperties", except that the items in model "ChamberProperties" are user defined and not limited. Say model "Chamber" has 2 objects in it: class Chamber(models.Model): chamber_name = models.CharField(max_length=100) With: Object 1: chamber_name: Lab Object 2: chamber_name: Production And the properties of the chambers are set up by the managers on site, so we don't know what they'll end up putting there. And the model "ChamberProperties" can have many related objects in it: class ChamberProperty(models.Model): chamber = models.ForeignKey(Chamber, on_delete=models.CASCADE) property_name = models.CharField(max_length=50) property_value = models.CharField(max_length=100) And for ChamberProperties: For example Chamber "Lab" may have: **ChamberProperties**: 1. Charge: 100v 2. Last test: yesterday 3. Scientist: Tom But Chamber "Production" may have many more: **ChamberProperties**: 1. Charge: 100000v 2. Error: 2018-02-19 11:55 3. Site: XK-1 4. Production: Foo 5. Risk: High My problem is in creating a table that shows all properties for all chamber in a HTML table. Both in constructing the HTML table itself and with filtering in the view. The table layout I was given is … -
Django celery beat with Django as backend

Django 2 url path matching negative value
In Django <2 the normal way of doing this is to use regex expression. But it is now recommended in Django => 2 to use path() instead of url() path('account/<int:code>/', views.account_code, name='account-code') This looks okay and works well matching url pattern /account/23/ /account/3000/ However, this issue is that I also want this to match negative integer like /account/-23/ Please how do I do this using path()? -

Ensure that a path to a dir is a Django project
For the last two days I am struggling with the following question: Given an absolute path (string) to a directory (inside my file system or the server, it doesn't matter), determine if this dir contains a valid Django project. First, I thought of looking for the manage.py underneath, but what if some user omit or rename this file? Secondly, I thought of locating the settings module but I want the project root, what if the settings is 2 or more levels deep? Third, I thought of locating the (standard) BASE_DIR name inside settings, but what if the user has not defined it or renamed it? Is there a way to properly identify a directory as a valid Django project? Am I missing something? -

django rest framework an always sorting field
I want to have a fixed sorting field applied to all custom sortings. To be more specific imagine we have a list of employees, if user choose this form be sorted by hire_date, I want the result be sorted by hire_date and employee_id together. I mean each ordering should be ordered by employee_id inside! For example if we have 5 employees hired today, if hire_date is the sorting field, these 5 be sorted by employee_id and for the other days the same story. using the following is not the cure. It only sorts them on employee_id when no ordering is set: queryset = models.Employee.objects.order_by('id') And this one's result is same as previous: filter_backends = (CustomFilterSetBackend, filters.OrderingFilter) custom_filters = ( ........ ) ordering_fields = (............) ordering = ('id',) tnx a million -
Django 2: TemplateDoesNotExist even if files placed properly

Django 1.11 - xadmin app, charts widget parameters
I'm using the xadmin app, specifically trying to work with the included charts plugin. How do I start adding data from my database / models into the chart?

Django Delete CBV with confirmation pop-up and multiple success url
In my case, an instance Model can be delete from: a ListView inherited View a DetailView inherited View By default, when a delete view is called: the get function calls 'confirm_delete' template.

Django Python - adding value to TimeField
I'm creating a basic model through the Django framework in Python, which demonstrates an offer on a product which will expire after 3 hours.

(NB: The date is not important, which is why I have used a TimeField). Is there a simple way to automatically set the "offer_expires" field to 3 hours after the time in the "offer_started" field? Or if not linked to this field directly, the time that the entry is added? Many thanks! -

__get__() method without owner, instance parameters DJANGO
Quick question about something I am struggling with. Reading the Python-documentation, __get__ is defined with the necessary parameters: object.__get__(self, instance, owner) I am currently learning about writing custom middleware within Django.

How can the middleware- __call__ take request and skip instance and owner? Thank you! -
Django strange SlugField validation, error not raised before clean()
django 2.0 I have a django model, with a slug as primary key from django.core.validators import validate_slug class MyModel(models.Model): # with slug field alias = models.SlugField(max_length=200, primary_key=True, unique=True) # or charfield with slug validator (should be exactly the same) alias = models.CharField(max_length=200, primary_key=True, unique=True, validators=[validate_slug]) The problem i have, in my form i have a clean method, to validate the values of multiple fields, not individually. This method should theoretically be called after the clean_fields method, but with the SlugField, it seems the field validation is not raised before the form's clean() method. My forms.py: class MyForm(forms.ModelForm): class Meta: model = MyModel fields = '__all__' def clean(): cleaned_data = super().clean() cleaned_data['alias'] # key error with SlugField return cleaned_data To resume, with the CharField with validate_slug, everything works as intented, validation error is raised in my form, before the clean() method But with SlugField, the validation error is not raised and i got a key error because the field is missing, because not valid, even if the exception was not raised. To trigger the validation error i use accented characters, 'ééé', but allow_unicode is set to False by default.
