How to query data from strapi by relation using grqphql? - graphql

Question

I have two tables in my Strapi, one is question and another one is question_option.
I have question_id in question_option table. I want to select all questions with their option. The problem is there that in Strapi we must query from question_option, we can't do it from question. According to every option, for example, if I have 30 option, it brings question 30 times. So how can I select a question that brings its options?
query{
questionOptions(filters: { question_id:{for : { contains: "owner" }}}){
data{
id
attributes{
option,
score,
status,
question_id{
data{
id
attributes{
title
}
}
}
}
}
}
The result is like:
{
"data": {
"questionOptions": {
"data": [
{
"id": "44",
"attributes": {
"option": " 0-10",
"score": "1",
"status": "1",
"question_id": {
"data": {
"id": "5",
"attributes": {
"title": "Client Base"
}
}
}
}
},
{
"id": "45",
"attributes": {
"option": "11-50",
"score": "1",
"status": "1",
"question_id": {
"data": {
"id": "5",
"attributes": {
"title": "Client Base"
}
}
}
}
},
{
"id": "46",
"attributes": {
"option": "51-100",
"score": "1",
"status": "1",
"question_id": {
"data": {
"id": "5",
"attributes": {
"title": "Client Base"
}
}
}
}
},
{
"id": "47",
"attributes": {
"option": "101-200",
"score": "1",
"status": "1",
"question_id": {
"data": {
"id": "5",
"attributes": {
"title": "Client Base"
}
}
}
}
},
{
"id": "48",
"attributes": {
"option": "over 200",
"score": "1",
"status": "1",
"question_id": {
"data": {
"id": "5",
"attributes": {
"title": "Client Base"
}
}
}
}
},
{
"id": "49",
"attributes": {
"option": "Bohemian ",
"score": "1",
"status": "1",
"question_id": {
"data": {
"id": "6",
"attributes": {
"title": "Style Identity"
}
}
}
}
},
{
"id": "50",
"attributes": {
"option": "Casual ",
"score": "1",
"status": "1",
"question_id": {
"data": {
"id": "6",
"attributes": {
"title": "Style Identity"
}
}
}
}
},
{
"id": "51",
"attributes": {
"option": "Clean ",
"score": "1",
"status": "1",
"question_id": {
"data": {
"id": "6",
"attributes": {
"title": "Style Identity"
}
}
}
}
},
{
"id": "52",
"attributes": {
"option": "Classic ",
"score": "1",
"status": "1",
"question_id": {
"data": {
"id": "6",
"attributes": {
"title": "Style Identity"
}
}
}
}
},
{
"id": "53",
"attributes": {
"option": "Colorful ",
"score": "1",
"status": "1",
"question_id": {
"data": {
"id": "6",
"attributes": {
"title": "Style Identity"
}
}
}
}
}
]
}
}
}
As you see, it brought for me the question for every option.

Basically you have to set a relation field between question and question_option content types. Without knowing the purpose of question_option I can't say exactly what type of relation it should be. Looking at the returned values I can only assume it should be question has many question_options. You'll have to consider it yourself and set the relation field accordingly. Once it is set and you see a question_option or question_options relation in your question content type, depending on the type of the relation you specified, you can query questions with their options.
