querying nested objects with relationships in realm react native
I am trying to use realm DB in my project. here the schemas:
export const AllParentObj = {
name:"AllParentObj",
properties:{
AllObjects:"OneChildObj"
}
}
export const OneChildObj = {
name:"OneChildObj",
properties:{
chKey:"string",
chItems:"subChild"
}
};
export const subChild = {
name:"subChild",
properties:{
subChName:"string",
subChMsg:"string"
}
};
and here is the way i am trying to read from realm:
let myCode = "langid1";
let myid="xyz";
let allObjs = this.DBRealm.objects('AllParentObj').
filtered(`AllObjs.chkey== '${myCode}' AND
AllObjs.chItems.subChName== '${myid}'`);
the above query returning all the results of query AllObjs.chkey== '${myCode}'
the other condition is not taken for filtering. Is there any place i am making mistake in the above code?
i want the output from my filter to be the matching page inside a given lang code.
ex:
sample input json in my realm DB:
{
"AllMessages":[
{
locale:"langid1",
pages:[
{
"pageName":"pagename",
"messages":
{
"ml1p1m1":"msgText",
"ml1p1m2":"ml1 m2text"
}
},
{
"pageName":"xyz",
"messages":
{
"ml1p2m1":"ml1p2m1 text",
"ml1p2m2":"ml1p2m2 text"
}
},
{
"pageName":"rtyui",
"messages":
{
"ml1p2m1":"ml1p3m1 text",
"ml1p2m2":"ml1p3m2 text"
}
},
]
},
{
locale:"langid2",
pages:[
{
"pageName":"abcd",
"messages":{
"ml2p1m1":"ml2p1m1 text",
"ml2p1m2":"ml2p1m2 text"
}
},
{
"pageName":"hjk",
"messages":{
"ml2p2m1":"ml2p2m1"
}
},
]
},
]
}
Output: for langid1 and pageName: xyz
{
"pageName":"xyz",
"messages":
{
"ml1p2m1":"ml1p2m1 text",
"ml1p2m2":"ml1p2m2 text"
}
}
can somebody please help?
PS: there are not syntax errors. basically multiple filters are not getting applied. when i apply single filter even on a subChild level its working.
