Great tut!

What if I want to put a thumb near the text?

Thanks!

i'm using this for "episodes" instead of "movies" so i have:

json.episodes do
json.array!(@episodes) do |episode|
json.title "Ep #{episode.episode}: #{episode.title}"
json.icon "#{episode.podcast.logo}"
json.url episode_path(episode)
end
end

json.podcasts do
json.array!(@podcasts) do |podcast|
json.title "#{podcast.title}"
json.icon "#{podcast.logo}"
json.url podcast_path(podcast)
end
end

and my search.js adds template function as well:

window.addEventListener("load", function() {
$input = $("[data-behavior='autocomplete']")

var options = {
getValue: "title",
url: function(phrase) {
return "/search.json?q=" + phrase;
},
categories: [
{
listLocation: "episodes",
header: "Episodes",
},
{
listLocation: "podcasts",
header: "Podcasts",
}
],
template: {
type: "iconLeft",
fields: {
iconSrc: "icon"
}
},
theme: "blue-light",
list: {
onChooseEvent: function() {
var url = $input.getSelectedItemData().url
$input.val("")
window.location = (url)
},
showAnimation: {
type: "fade",
time: 300,
callback: function() {}
},
hideAnimation: {
type: "fade",
time: 300,
callback: function() {}
},
}
}

$input.easyAutocomplete(options)
});

Chris thank you for this video, super helpful! I get a strange error though when following you at the end. In my navbar page - "undefined method `form_with' for #<#<class:0x007f875a6f8b58>:0x007f87600e0aa8>" I decided to hack away and switch form_with for form_tag but then I get an error on the line immediately below "undefined method `text_field' for nil:NilClass" I double checked my code and don't know what could be causing it. Any help would be amazing sir thanks :)

Hey Omar, in your gem file change rails gem to the latest: gem 'rails', '~> 5.1.1' or higher
consol: bundle update
Restart your rails application
Hope this works for you

Had the same issue and rewrote the form_tag, for code see my comment above

SHouldn't jquery and all dependencies be in /vendor/assets/javascripts folder? Just asking.. I thouhgt that is the 'recommended way'..

For anyone on Rails <5.1, this example code for `form_tag` can be used to replace `form_with`:

<%= form_tag('/search', local: true, method: :get, class: 'form-inline' ) do %>
<%= text_field_tag(:q, nil, data: { behavior: 'autocomplete' }, placeholder: 'Search', class: 'form-control mr-sm-2') %>
<%= button_tag('Search', class: 'btn btn-outline-success my-2 my-sm-0', type: 'submit') %>
<% end %>

or more readable as GitHub gist: https://gist.github.com/spe...

Hi Chris,

Thanks for this it has really helped me!

Does anyone know the best way to search multiple columns from model?

Something like : Search Movies by name and date and genre.

Any pointers would be appreciated!

Dan

Hi Chris, I'm trying to get my search form back to mobile responsive.
data: { behavior: "autocomplete" } in the form triggers easy-autocomplete functionality. But the search form/layout becomes mobile unresponsive when I add "data: { behavior: "autocomplete" } " Please do you know how I can fix this in the easy-autocomplete css file?

<%= form_with url: search_path, local: true, method: :get, :class => "" do |form| %>
<div class="input-group m-b-20">
<%= form.text_field :q, placeholder: "Search and select or hit enter", data: { behavior: "autocomplete" }, class: "form-control input-lg" %>

<button type="submit" class="btn btn-lg"></button>
</div>

<% end %>

if you're not using turbolinks (which i'm not), replace search.js with:

window.addEventListener("load", function() {
$input = $("[data-behavior='autocomplete']")

var options = {
getValue: "title",
url: function(phrase) {
return "/search.json?q=" + phrase;
},
categories: [
{
listLocation: "movies",
header: "Movies",
},
{
listLocation: "directors",
header: "Directors",
}
],
list: {
onChooseEvent: function() {
var url = $input.getSelectedItemData().url
$input.val("")
window.location = (url)
}
}
}

$input.easyAutocomplete(options)
});

When I try to use .easyAutocomplete from console I get this error:

TypeError: $('input').easyAutocomplete is not a function. (In '$('input').easyAutocomplete(options)', '$('input').easyAutocomplete' is undefined)

And I get this as well that call css.map ????

http://localhost:3000/assets/easy-autocomplete.themes.cs... Failed to load resource: the server responded with a status of 404 (Not Found)

http://localhost:3000/assets/easy-autocomplete.css.map. Failed to load resource: the server responded with a status of 404 (Not Found)

I follow this tutorial but I get these error... Thank you very much if someone know how solve it!

Rodrigo, could you figure out  ? i have the same issue

Hi Chris I want to add a second search field to the search form, say to search for the location of the Directors. Just like yell.com, where you can enter the search term and the location in different text fields. Could you please help on how to write the ransack logic in the form and the main_controller?  
Thanks

Would love to see this in Vue within an app-wrapper (data-behavior='vue') like you talked bout in ep 239! I've been banging my head against a number of these options (https://github.com/vuejs/awesome-vue#autocomplete) within the context of a Rails app.

Hi Chris, 
At some stage you remove :

render json: {users: [], events: [], entreprises: []}

And from there i have

MainController#search is missing a template for this request format and variant. request.formats: ["application/json"] request.variant: []

Is there something your video is skipping please?

How can I fetch a full country name in the search.json.jbuilder. I am using the Country_select gem and autocomplete results is showing only a country short code like GB for United Kingdom.

Here is my code in the search.json.jbuilder:
json.movies do
  json.array!(@movies) do |movie|
    json.name movie.title.titleize + " " + "in" + " " + movie.country
    json.url movie_path(movie)
  end

movie.rb
 def country_name
    country = self.country
    ISO3166::Country[country]
   end

In your movie.rb change your country_name to:

 def country_name
    country_name = ISO3166::Country[country]
    country_name.translations[I18n.locale.to_s] || country_name.name
  end

Now you can do this movie.country_name which will convert your country code to the full name like this RU:Russia or CA:Canada, and etc:

# your code
json.name movie.title.titleize + " " + "in" + " " + movie.country_name
# your code

Thank you for the tutorial.

I get all of this to work until the final part of hooking it to the form field (I am using Bootstrap for forms).

I use the name "databehavior" rather than "data-behavior".
When I enter the field on the form I get autocomplete suggestions but they are from other inputs unrleated to the app. It seems that the search.js code is not being executed.

Any ideas?

Here is the form input code:
<%= form_with url: search_path, local: true, method: :get, html: {class: "form-inline my-2 my-lg-0" } do |form| %>
<%= form.text_field :q, placeholder: "College", data: { behavior: "autocomplete" },
databehavior: "autocomplete", class: "form-control mr-sm-2"%>
<% end %>

Here is the search.js code:
document.addEventListener("turbolinks:load", function() {
$input =$("[databehavior='autocomplete']")

var options = {
getValue: "name",
url: function(phrase) {
return "/search.json?q=" + phrase;
},
categories: [
{
listlocation: "users",
header: "Users",
}
]
}

$input.easyAutocomplete(options)
});

In case anyone looks at the post above, I have broken down the sequence into steps and have "proven" that the javascript runs correctly in the browser and that the controller is producing the JSON array. But nothing is showing up on the page. Any ideas on what could be the problem? How I could see the JSON object returned and in the browser and/or how it fails with the autocomplete gem?

I am getting an error when I run the finished code: search.js:31 Uncaught TypeError: $input.easyAutocomplete is not a function

However, when I put create an options variable directly in the console and run:
$input = $("[data-behavior='autocomplete']")
and then
$input.easyAutocomplete(options)

it works fine. Any idea why I am able to run easyAutocomplete directly in the console but not in the normal course of my app? Here is my application.js file:

// Rails functionality
window.Rails = require("@rails/ujs")
require("turbolinks").start()
require("@rails/activestorage").start()
require("channels")
require("trix")
require("@rails/actiontext")

require("jquery")
require("easy-autocomplete")

require("custom/show")
require("custom/search")

// Tailwind CSS
import "stylesheets/application"

// Stimulus controllers
import "controllers"

// Jumpstart Pro & other Functionality
import "src/actiontext"
import "src/confirm"
import "src/direct_uploads"
import "src/forms"
import "src/timezone"
import "src/tooltips"

import LocalTime from "local-time"
LocalTime.start()

// ADD YOUR JAVACSRIPT HERE

// Start Rails UJS
Rails.start()

Any ideas on this? Thanks!
