This utility is useful when you want to safely retrieve a single object from the database without having to wrap get() in a try/except block every time. It also supports query optimization via select_related and prefetch_related, making it ideal for performance-conscious applications.
This will help to secure the sensitive secrets, token, api keys, etc from logger. As we know there is security issue when we include the sensitive information to the logger in case logger got leaked/hacked. Before: ``` INFO ('192.168.1.1', 33321) - "WebSocket /ssh?token=abcdefg&width=20&heigh20" ``` After: ``` INFO ('192.168.1.1', 33321) - "WebSocket /ssh?token=********&width=20&heigh20" ```
If you have multiple items in a list and want them to be displayed as human readable list of items, this will add the proper punctuation to generate the text. You'll need to provide a conjugation to the end of the list like "or" or "and"; it defaults to "or". Intended use: `{% for item in items %}{{item}}{% list_punctuation forloop "and" %}{% endfor %}` * If items was `['a']`; the template would return `a`. * If items was `['a', 'b']`; the template would return `a and b`. * If items was `['a', 'b', 'c']`; the template would return `a, b, and c`.
add JSONRequestMiddleware to your enabled middleware in Django settings. Now, in your view functions, you can call request.json() to get a parsed json body! json is consumed lazily, and cached.
Creates a model serializer class on the fly, just taking the model (class) as its argument. My use case: When importing data from spreadsheets, the DRF serializers are an easy way to create model instances from a dictionary. This function saves me from creating a custom serializer each time I add a new importer. Using `__all__` is dangerous ;-)
Don't forget to replace "self.image" by your image field name from your model ex ( self.cover ) replace Product by your model name works pretty well :)
Sometimes a plain-text help-text isn't sufficient, and it's handy to be able to add links to pages, documentation or external websites. This javascript snippet can be added to your page, in combination with adding a class to your help text in your template. This assumes you're using jQuery on your website. Field template snippet: ``` {% if field.help_text %}<p class="help-text">{{ field.help_text }}</p>{% endif %} ``` On document ready, this will convert the markdown-style links into anchor tags, allowing you to have richer help text for your users
A simple jQuery javascript that collapses all stacked inline rows for better handling of large inline fieldsets. It also adds "Show"/"Hide"-buttons for showing/hiding each row, which could be customized and styled using css. **Usage (see below for example):** Include the javascript on your admin page, together with jQuery, and it'll automatically affect all stacked inlines. **Works with** Django 3.1.4 (Might work with other versions with or without adjustments, but not tested) **Use example:** *admin.py:* class DateInline(admin.StackedInline): model = Date extra = 10 class EventAdmin(admin.ModelAdmin): inlines = [DateInline] class Media: js = ['js/collapsed-stacked-inlines.js'] admin.site.register(Event, EventAdmin)

Add fields and extend Django's built-in `Group` model using a `OneToOneField` (i.e. a profile model). In this example, we add a `UUIDField`. Whenever a new group is created, we automatically (via signals) create a corresponding `Role` record referencing the newly created group. Whenever a Group is deleted, the corresponding Role is deleted as well.
A more simple version of [https://djangosnippets.org/snippets/1688/](https://djangosnippets.org/snippets/1688/), inheriting from `SelectDateWidget`, overriding only the necessarily. **Usage example:** **In models.py:** from django.db import models from django.utils.translation import gettext_lazy as _ class MyModel(models.Model): start = models.DateField( _("Start date"), ) end = models.DateField( _("End date"), ) class Meta: verbose_name = _("My model") **In forms.py:** from django import forms from .models import MyModel from .widgets import MonthYearWidget class MyModelForm(forms.ModelForm): class Meta: model = MyModel exclude = [] widgets = { "start": MonthYearWidget(), "end": MonthYearWidget(last_day=True), } **kwargs:** - *last_day :* if set to `True`, returns the last day of the month in the generated date.

Most modern browsers support the new `<input type="date">`, which allows inputting date using a browser-native date picker with built-in validation. This form widget utilizes this feature by setting the input type to "date" and by changing the value formatting as it should be in the ISO format. See more about `<input type="date">`: <https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/date>
