I have a requirement to sort the data and below is what my data looks like.
[
{
"id": "course1",
"type": "course",
"sequence": 1
},
{
"id": "course2",
"type": "course",
"sequence": 2
},
{
"id": "course1_chapter1",
"type": "chapter",
"sequence": 1,
"course": {
"id": "course1",
"sequence": 1
}
},
{
"id": "course1_chapter2",
"type": "chapter",
"sequence": 2,
"course": {
"id": "course1",
"sequence": 1
}
},
{
"id": "course2_chapter1",
"type": "chapter",
"sequence": 1,
"course": {
"id": "course1",
"sequence": 2
}
},
{
"id": "course1_chapter1_lesson1",
"type": "lesson",
"sequence": 1,
"course": {
"id": "course1",
"sequence": 1
},
"chapter": {
"id": "chapter1",
"sequence": 1
}
},
{
"id": "course1_chapter1_lesson2",
"type": "lesson",
"sequence": 2,
"course": {
"id": "course1",
"sequence": 1
},
"chapter": {
"id": "chapter1",
"sequence": 1
}
},
{
"id": "course1_chapter2_lesson1",
"type": "lesson",
"sequence": 1,
"course": {
"id": "course1",
"sequence": 1
},
"chapter": {
"id": "chapter1",
"sequence": 2
}
}
]
Now my requirement is to sort the data based on type 1st where the order should be course, chapter, and lesson, and then order based on the sequence. So my final outcome expectation is as per the above data
course1, course2, course1_chapter1, course1_chapter2, course2_chapter1, course1_chapter1_lesson1, course1_chapter1_lesson2, course1_chapter1_lesson2, course1_chapter2_lesson1
The sample data which I have mentioned is already in sorted manner but in real time scenario, I get unsorted data.
right now I have sorted just by Type using the score.
I could do the sorting by splitting the data into different variable and finally get the sorted data into single variable but would like to know if there is any advance option which I might not be aware.
