I'm trying to make a poll vote app. My big problem is that I can't make an array of objects and access them. I try to make a few option votes to one poll like that:
title:"question?"
option:content:"1 answer",vote:0
content:"2 answer",vote:0
content:"3 answer",vote:...
and build schema like that:
var mongoose = require("mongoose");
var pollSchema = new mongoose.Schema({
title: String,
maker :{
id:{
type: mongoose.Schema.Types.ObjectId,
ref: "User"
},
username: String
},
options:[{content: String,vote:{type:Number,default:0}}]
});
module.exports = mongoose.model("Poll",pollSchema);
and get the data from there:
<div class="form-group" id="option">
<label for="Option 1">Options</label>
<input type="text" class="form-control" name="options[content]" placeholder="Option 1">
<input type="text" class="form-control" name="options[content]" placeholder="Option 2">
</div>
and the output in mongoDB is:
{
"_id": {
"$oid": "5993030dc5fa8c1b4f7eb176"
},
"title": "Some question?",
"options": [
{
"content": "opt 1,opt 2",
"_id": {
"$oid": "5993030dc5fa8c1b4f7eb177"
},
"vote": 0
}
],
"maker": {
"username": "Naor Malca"
},
"__v": 0
}
I want each option to have separate content
, id
and vote
.
maybe i input the data worng?or the schema is worng?
UPDATE: This my route code:
//NEW POLL ROUTE
app.post("/",function(req, res){
var title = req.body.title;
var options = req.body.options;
var maker = req.body.maker;
var newPoll = {title:title,options:options,maker:maker};
Poll.create(newPoll,function(err,poll){
if(err){
res.send("create error");
} else{
res.redirect("/");
}
});
});
still not working this the output:(its make the text an array not a array of objects...)
{ _id: 5993fcad9a63350df274b3e5,
title: '111',
__v: 0,
options: [ { text: '222,333', _id: 5993fcad9a63350df274b3e6, vote: '0' } ],
maker: { username: 'naor' } }

When you build your form, add [number]
so that each option is different.
<div class="form-group" id="option">
<label for="Option 1">Options</label>
<input type="text" class="form-control" name="options[0][content]" placeholder="Option 1" value="value1">
<input type="text" class="form-control" name="options[1][content]" placeholder="Option 2" value="value2">
</div>
That way when you submit the form, it should come back as array of objects
req.body.options = [
{ content: 'value1' },
{ content: 'value2' }
]
This is a typical approach when you build an "add" form containing grouped elements.

When it comes to an "edit" form such that you want to update existing options, you can pass the option's _id
Here's an example using EJS
<div class="form-group" id="option">
<label for="Option 1">Options</label>
<% poll.options.forEach(option => { %>
<input type="text" class="form-control" name="options[<%= option._id %>][content]" placeholder="Option 1" value="<%= option.content %>">
<% }) %>
</div>
Here req.body.options
should be an object
req.body.options = {
'some-id': {
content: 'value1'
},
'another-id': {
content: 'value2'
}
}
When you save, you would iterate over the object with the key i.e. _id
. I think you can make use of id() to find the object to set.

If it doesn't come back in the formats mentioned above, you most likely need to use and set the bodyParser.
