some of the document does not consists planDetails planId properties and its returning error "can't convert undefined to an object , but i have to fetch that document if these properties exists or not , how can i avoid this error
this.profile.find({ userId: ObjectId(req.id) }).populate("planId").lean().exec(function(err, profileFound) {
console.log(profileFound);
if (err) return callback(err);
if (profileFound && profileFound.length === 0) {
return callback(false, common.errorMsg("PROFILE DOES NOT EXIST"));
} else {
var profileData = profileFound[0];
profileData["isPlanTaken"] = false;
profileData["planDetails"] = {};
if(profileData.hasOwnProperty("planId") && profileData.planId){
if(Object.keys(profileData.planId).length>0){
profileData["isPlanTaken"]=true;
profileData["planDetails"]=profileData.planId;
}
}
return callback(
false,
common.successMsg("PROFILE FETCHED",profileData )
);
}
});
I think there was missing the initialization of profileData variable only...
const profileData = {};
profileData["isPlanTaken"] = false;
console.log(profileData);
profileData["planDetails"] = {};
if(profileData.hasOwnProperty("planId") && Object.keys(profileData.planId)){
profileData["isPlanTaken"]=true;
profileData["planDetails"]=profileData.planId;
}
console.log(profileData);And I think that is also enough to check a property is exists in an object. Can you please give me more data for example, because I don't really know what do you need.
const profileData = {};
profileData.isPlanTaken = false;
console.log(profileData);
profileData.planId = 5; // for example
if (profileData.planId) {
profileData.isPlanTaken = true;
profileData.planDetails = profileData.planId;
}
console.log(profileData);
