Autocomplete works ok when searching with a single attribute as given here.
Autocomplete with multiple attributes such as (name,city,country) is possible through->(according to this)
def autocomplete
Doctor.search(params[:query], autocomplete: true, limit: 10).map{|doctor| doctor.slice(:name, :city, :country) }
end
However this results in the autocomplete dropdown/suggestions to show "undefined".
For type ahead i am using:
<script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/typeahead.js/0.9.3/typeahead.min.js"></script>
In the code it is referenced by:
$( function () {
$("#search").typeahead({
name: "doctor",
remote: "/doctors/autocomplete?query=%QUERY"
});
});
Is some change required in the typeahead js file because of more than one set of data being returned?
You need to return a hash
Your autocomplete
action in doctors
controller need to look like this :
def autocomplete
render json: Doctor.search(params[:query], autocomplete: true, limit: 10).map do |doctor| { name: doctor.name, city: doctor.city, country: doctor.country }
end
end
Add displayKey
in your typeahead option:
$( function () {
$("#search").typeahead({
name: "doctor",
displayKey: 'name',
remote: "/doctors/autocomplete?query=%QUERY"
});
});

Based on the above answer and this and this
What worked is shown below:
def autocomplete
names = Doctor.search(params[:query], fields: [{name: :text_start}], limit: 10).map {|Doctor| {store: doctor.name, value: doctor.id}}
collegenames = Doctor.search(params[:query], fields: [{collegename: :text_start}], limit: 10).map {|Doctor| {store: doctor.collegename, value: doctor.id}}
render json: (names + collegenames)
end
The variable store: now contains all the data.
Javascript:
var ready;
ready = function() {
console.log("dfdf")
var numbers = new Bloodhound({
datumTokenizer: function(d) {
console.log(d);
return Bloodhound.tokenizers.whitespace('value');
},
queryTokenizer: Bloodhound.tokenizers.whitespace,
remote: {
url:"/doctors/autocomplete?query=%QUERY"
}
});
// initialize the bloodhound suggestion engine
var promise = numbers.initialize();
promise
.done(function() { console.log('success!'); })
.fail(function() { console.log('err!'); });
// instantiate the typeahead UI
$('.typeahead').typeahead(null, {
displayKey: 'store',
source: numbers.ttAdapter()
});
}
$(document).ready(ready);
$(document).on('page:load', ready);
Autocomplete works great on both fields however now i get an empty array on writing a url like
http://localhost:3000/doctors/autocomplete?query="a"
