Fix parent child timetable switching

[sveco86]

Summary

Fix parent account timetable switching when working with multiple children.

Problem

switch_to_child() used an exact type comparison:

type(child) == EduAccount

This does not work correctly when an EduStudent instance is passed, even though EduStudent is a subclass of EduAccount.

Additionally, get_my_timetable() did not retain information about the explicitly selected child and continued using the legacy timetable path.

Changes

• Use isinstance(child, EduAccount) in switch_to_child().
• Store the selected child ID after a successful child switch.
• Clear the selected child ID when switching back to the parent.
• When a child is explicitly selected, get_my_timetable() resolves that student and uses the newer get_timetable(student, date) implementation.
• Add an example demonstrating timetable retrieval for a selected child.

Testing

Tested with a parent account containing multiple children. Switching between the children now returns the correct timetable for each selected child.

Addresses #106.

Related to #95: the newer timetable path also avoids the legacy /gcall request that can fail for some accounts. This PR does not completely fix #95 because get_my_timetable() without an explicitly selected child still uses the legacy implementation.

Hi, can you provide me a step by step explanation where I find the line to change and what to change?
Maybe I will find the right lines at the PC, but at my mobile I don‘t

I have updated example script, check it: examples/timetables.py

don't get me wrong, I'm happy that you tried to help me, but I'm lost all the time.
Where do I have to change the code? Where do I find the right place for changing? Is the code in Homeassistant? When yes what folder?
With the help of google I found something according to the edupage api at the web access, but I don't have admin rights, because I'm just a simple dad...I will fix this problem, but I can't for my own...sorry

In file editor -> home assistant/custom components/homeassistantedupage/homeassistant_edupage.py ??

Hi @WernAir77,

Here's what changed and a complete example you can use right away.

What Was Fixed

This PR fixes parent accounts with multiple children. The issue was that switch_to_child() didn't work properly with EduStudent objects. Now it:

1. Correctly recognizes EduStudent (subclass check instead of exact type)
2. Remembers which child is selected
3. Uses the newer, more reliable timetable path for that child

Complete Example Script

Here's a simple script showing exactly how to use it:

from edupage_api import Edupage
import datetime

# 1. Log in
edupage = Edupage()
edupage.login("your_email@example.com", "your_password", "edupage_school_domain")

# 2. Get your children
students = edupage.get_students() or []

if not students:
    print("No children found")
else:
    print("Available children:")
    for i, student in enumerate(students):
        print(f"  {i+1}. {student.name}")
    
    # 3. User selects a child by number
    try:
        choice = int(input("\nSelect child number (1, 2, ...): "))
        child = students[choice - 1]
    except (ValueError, IndexError):
        print("Invalid choice!")
        exit()
    
    # 4. Switch to the selected child
    print(f"\nSwitching to: {child.name}")
    edupage.switch_to_child(child)
    
    # 5. Get the child's timetable
    today = datetime.date.today()
    timetable = edupage.get_my_timetable(today)
    
    # 6. Display it
    print(f"\nTimetable for {child.name} on {today}:")
    print("-" * 50)
    
    if timetable:
        for lesson in timetable:
            subject = lesson.subject.name if lesson.subject else "Unknown"
            teacher = lesson.teachers[0].name if lesson.teachers else "?"
            print(f"[Period {lesson.period}] {subject} ({teacher})")
    else:
        print("No lessons found")

** How To Use It **##

1. Save this as a .py file
2. Replace your_email@example.com, your_password and edupage_school_domain with your actual login data
3. Run it: python script_name.py

This is NOT Home Assistant code - it's the edupage-api Python library. If you're using Home Assistant, this library runs behind the scenes.

I will test it tomorrow.

Know I understand were we lost each other...you where talking about the api and python and I was talking about Homeassistant. It would be great if it worked there too

I tested it. For my problem it isn’t a solution, because I seems that the structure of the database at my school is different from the one the api expected. I‘m able to choose a child, but I can‘t get the timetable.
