Wagtail as Django admin on steroids

A good analysis for Django developers: Wagtail can be used not only as a CMS, but also as a more convenient admin interface for regular Django models.

The idea is simple: Django admin quickly provides a UI around models, but customization often becomes a hassle. Wagtail offers a more modern interface, proper handling of fields, grouping via panels, roles, permissions, rich text, media library, versioning, and editorial workflows.

At the same time, there's no need to rewrite the project to fit CMS logic. Wagtail is installed as a regular Django package, added to INSTALLED_APPS, and integrated into urls.py. The business logic, views, forms, and templates remain regular Django components.

The most practical use case: take an existing admin.py, move the models to Wagtail snippets, and gradually replace the old admin interface where you need an interface that's not embarrassing to show to clients.

For internal tools, CRMs, backoffices, and content sections, this can be much more pleasant than endlessly tweaking the standard Django admin.

**Today we will examine __call__ β€” a data filter object!** 🧠

It allows a class instance to work as a function, preserving the state and filtering rules. βš™οΈ

Let's create a filter for numbers that only passes even ones and strictly greater than a specified threshold:

class EvenFilter:
def __init__(self, threshold):
self.threshold = threshold

def __call__(self, numbers):
return [n for n in numbers if n % 2 == 0 and n > self.threshold]

Let's use the filter in practice:

f = EvenFilter(5)
nums = [1, 4, 6, 7, 10]
print(f(nums)) # [6, 10]

Now each instance can have its own rules:

f2 = EvenFilter(8)
print(f2(nums)) # [10]

πŸ”₯ So, __call__ turns an object into a "smart function" with memory and customizable logic. πŸ’‘

collections.Counter β€” counting elements in a single line. πŸ“Š

Counting elements without loops with Counter πŸ”„

Do you need to count how many times each word appears in a text or how many duplicates there are in a list? Don't reinvent the wheel with for loops and dictionaries. The built-in collections module will do everything for you. πŸš€

πŸ›  Code:
from collections import Counter

words = ["apple", "banana", "apple", "cherry", "banana", "apple"]
word_counts = Counter(words)

print(word_counts)
# Output: Counter({'apple': 3, 'banana': 2, 'cherry': 1})

# Bonus: the top 2 most frequent elements
print(word_counts.most_common(2))
# Output: [('apple', 3), ('banana', 2)]

Ideal for basic data analysis and solving tasks on LeetCode. πŸ’»
