mongodb - Update nested sub document using Node.js and mongoose -
i tried save details nested sub document tertiary.
module.exports = mongoose.model('todo', { title : string, image:string, bgimage:string, secondary:[secondary] }); var secondary = new mongoose.schema({ title : string, image:string, bgimage:string, tertiary :[tertiary] }); var tertiary = new mongoose.schema({ title : string, description:string, image:string }); the code saving tertiary data below. have primary object id secondary object id.
todo.findbyid(fields.primaryid, function (err, secondary_todo) { if (!err) { console.log("---inside not errot----"); console.log(fields.secondaryrefid); secondary_todo.secondary.findbyid(fields.secondaryrefid, function (err, tertiary_todo) { console.log("---in secondary data----"); console.log(tertiary_todo); if (!err) { tertiary_todo.tertiary.push({ _id: mongoose.types.objectid(), title : fields.title, image : fields.file, description : fields.description, }); } tertiary_todo.save(); }); } }); the error got in terminal
/......./.../..../lib/utils.js:419 throw err; ^ typeerror: object [object object],[object object],[object object] has no method 'findbyid' @ promise.<anonymous>
can give quick fix. tried , struck it.
you may want read this page in docs describing sub docs , special id() method used find sub document give id.
instead of calling findbyid on sub documents
secondary_todo.secondary.findbyid(fields.secondaryrefid, function (err, tertiary_todo) { ... use id
var tertiary_todo = secondary_todo.secondary.id(fields.secondaryrefid); ... update: issue schema setup broken use child schemas before defined. reorder them
var tertiary = new mongoose.schema({ title : string, description:string, image:string }); var secondary = new mongoose.schema({ title : string, image:string, bgimage:string, tertiary :[tertiary] }); module.exports = mongoose.model('todo', { title : string, image:string, bgimage:string, secondary:[secondary] });
