I'm a junior ruby on rails developer. I developed a web app that uses Google maps javascript API and I use the autocomplete function on a form input.
The autocomplete works fine on localhost but does not work anymore after deploying on heroku.
Here is my html.erb below. For your perfect information, the form is in the page footer. This form is partially hidden and the only visible part corresponds to a button used to upload a video file. Once this button has been clicked and the video file has been chosen, I display a modal containing the rest of the form. That's where the 'text_field_tag' (with the id = "user_input_autocomplete_address") is displayed and where the autocomplete should work.
<% if user_signed_in? %>

Last, the javascript code allowing the autocomplete on the input (having "user_input_autocomplete_address" as id) is in assets/javascript/autocomplete.js and is the following :
function initializeAutocomplete(id) {
var element = document.getElementById(id);
console.log('coucou');
if (element) {
var autocomplete = new google.maps.places.Autocomplete(element, { types: ['geocode', 'establishment'] });
google.maps.event.addListener(autocomplete, 'place_changed', onPlaceChanged);
}
}
function onPlaceChanged() {
var place = this.getPlace();
console.log(place); // Uncomment this line to view the full object returned by Google API.
for (var i in place.address_components) {
var component = place.address_components[i];
// console.log(component.types);
for (var j in component.types) { // Some types are ["country", "political"]
var type_element = document.getElementById(component.types[j]); // Returns the div with their differents ids or null if the id doesnt exist
// console.log(document.getElementById(component.types[j]));
if (type_element) {
type_element.value = component.long_name;
}
}
}
var formatted_address = document.getElementById('formatted_address');
// console.log(international_phone_number);
if (formatted_address) {
formatted_address.value = place.formatted_address;
}
for (var i in place.types) {
// console.log(place.types);
// console.log(i);
// console.log(place.types[i]);
var type_content = document.getElementById('category_' + i); // Returns the div with their differents ids or null if the id doesnt exist
// console.log(document.getElementById(component.types[j]));
if (type_content) {
console.log(place.types[i]);
type_content.value = place.types[i];
}
}
var international_phone_number = document.getElementById('phone_number');
// console.log(international_phone_number);
if (international_phone_number) {
international_phone_number.value = place.international_phone_number;
}
var name = document.getElementById('name');
if (name) {
name.value = place.name;
}
var gplace_id = document.getElementById('gplace_id');
if (gplace_id) {
gplace_id.value = place.place_id;
}
var website = document.getElementById('website');
if (website) {
website.value = place.website;
}
for (var i in place.opening_hours.weekday_text) {
var hours_open_in_db = place.opening_hours.weekday_text[i];
var hours_open_in_form = document.getElementById('hours_open_day_' + i);
if (hours_open_in_form) {
hours_open_in_form.value = hours_open_in_db;
}
}
}
google.maps.event.addDomListener(window, 'load', function() {
initializeAutocomplete('user_input_autocomplete_address');
});
In order to deploy all this on heroku, I already did the following :
"heroku run db:migrate" in the terminal (because I had some pending
migrations);
"figaro heroku:set -e production" in the terminal, in order to push all my API keys to heroku (I also checked that these keys are indeed in heroku's config vars).
in Google's developer console, within my project and within Google map javascript API, I ensured that my browser key is allowed for both my locahost and my domain name. In order to be very precise, I am using the same key for my locahost and my domain name. Until now, the only thing I have not managed to do yet, in Google's console, is to prove that I own my domain name.
I checked I have not reached any of my API quotas yet.
Within my autocomplete.js file, I used some console.log in order to find out, in my browser's inspector, what parts of the code are working. It seems that everything works except the console.logs that are in the 'OnPlaceChange' callback, since Gmap's autocomplete suggestions are not shown... ;
I know that not seeing the autocomplete suggestions is not a problem of z-index associated to the .pac-container css element, since I already had to fix this and since Gmaps suggestions cannot be reached thanks to my keyboard arrows.
I read this post about geocomplete (geocomplete for rails 4 not working in Heroku) and tried to precompile my assets. That did not lead to any change.
In my browser inspector (in the 'network' section), when I write something in my form input, every new letter pressed on the keyboard triggers a new request. These requests names are 'AutocompletionService.GetPredictions.....'. In the "headers" section, I can see they are https requests to googleapis, with get methods and 200 status code. In the "response" section, I can see there seems to be a error with my API keys since the message is :
/**/_xdc_._ty4oqn && _xdc_._ty4oqn( [3,null,null,"This API project is not authorized to use this API. Please ensure that this API is activated in the APIs Console: https://console.developers.google.com/apis/library?project=_ Please ensure this API is activated in the Google Developers Console: https://console.developers.google.com/apis/api/places_backend?project=_ For more information on authentication and Google Maps Javascript API services please see: https://developers.google.com/maps/documentation/javascript/get-api-key"] )
I followed the link in the error message, leading me to Google's console, and I get back to my project and API keys, which are settled both server-side and browser-side. Once again, the only thing i did not managed to do in Google's console was to prove I own my domain name.
Is this last point the origin of the issue (and in this case I guess I need some help from my hosting services) or do you guys see another mistake?
I has same issue too.
just goto google console, enable the "Google Places API Web Service", then it will solved the problem.
Enable "Google Places API Web Service" on Google API Console. It solved my problem when the website worked on localhost, but don't at Locaweb server.
I'm trying to get rid of the ugly button rails has as default for the file upload. i want to add a glyphicon
<%= f.file_field :image_url, class:"glyphicon glyphicon-camera" %>
This didn't work and I have tried other things in different post i saw on this page, but they don't attach the file.
You can do it using css.
HTML:
<div class="image-upload">
<label for="file-input">
<span class="glyphicon glyphicon-camera"></span>
</label>
<%= f.file_field :image_url, id:"file-input" %>
</div>
CSS:
.image-upload > input
{
display: none;
}
.image-upload > label{
cursor:pointer;
}
You can find the working example here
As suggested here Bootstrap Filestyle, you can use Bootstrap's Filestyle to style your file upload buttons.
Step-1: Add this to your layout application.html.erb
I have added the Bootstrap Filestyle library from CDN. You should make sure that you have both JQuery and Boostrap loaded.
<script type="text/javascript" src="https://cdn.jsdelivr.net/bootstrap.filestyle/1.1.0/js/bootstrap-filestyle.min.js"> </script>
Step-2: Add this to the corresponding js file:
$(":file").filestyle({input: false});
Step-3: Then your image_url file field could look like as follows:
<%= f.file_field :image_url,class: "filestyle", "data-input" => false %>
you can use also:-
add file field and hide this field :-
<%= f.file_field :image_url ,:onchange=>"loadFile(event)",id: "upload-it", class: "hide_input"%>
add one div with class:"glyphicon glyphicon-camera" :-
<div class="glyphicon glyphicon-camera" id="image-output",:onclick="upload_it(event)"></div>
use script:-
<script>
var loadFile = function(event) {
var output = document.getElementById('image-output');
output.src = URL.createObjectURL(event.target.files[0]);
};
function upload_it(){
$("#upload-it").click();
};
</script>
I am using ruby on rails devise for authentication. I need to validate the login form on client side. Devise uses user[email] as name attribute value. How do I use the same name in angularjs ng-show expression ?
<form ng-app="" ng-controller="validateCtrl" name="myForm" novalidate>
<input type="text" name="user[email]" ng-model="user" required>
<span ng-show="myForm.user[email].$error.required">Username is required</span>
</form>
user[email] does not work in angularjs ng-show expression.
Angular not access to ruby on rails variable.
You can do it in this way, this is my example using devise gem and angular 1.3.14
<%= form_for(resource, as: resource_name, url: registration_path(resource_name), html: {name: "profileForm", novalidate: false}) do |f| %>
<div class="field">
<%= f.label :firstname %><br />
<%= f.text_field :firstname, autofocus: true, "ng-model"=>"profile.firstname", required: true %>
<div ng-messages="profileForm['user[firstname]'].$error" class="errors">
<span ng-message="required">Required!</span>
</div>
</div>
<% end %>
NOTE: You will need to add angular-messages.js and the module in your app
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<script data-require="angular.js#1.3.14" data-semver="1.3.14" src="https://code.angularjs.org/1.3.14/angular.js"></script>
<script data-require="angular.js#1.3.14" data-semver="1.3.14" src="https://code.angularjs.org/1.3.14/angular-messages.js"></script>
.....
in your app.js
(function() {
var app = angular.module("myApp", ["ngMessages"]);
}());
I've been battling trying to get this working for the last few hours, and I just can't for some reason. I've followed the steps almost exactly as indicated on the github repository link.
I created a new application using all of the following steps:
# rails new demo_app
# cd demo_app/
+++ added gem 'cocoon' to the Gemfile
+++ added //= require cocoon to the application.js file
# rails g scaffold Project name:string description:string
# rails g model Task description:string done:boolean project:belongs_to
+++ added has_many :tasks to the Project model
+++ added :_destroy to the permit in my projects_controller.rb file
# bundle install
Here is my views/projects/_form.html.erb file:
<%= form_for(#project) do |f| %>
<% if #project.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#project.errors.count, "error") %> prohibited this project from being saved:</h2>
<ul>
<% #project.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :name %><br>
<%= f.text_field :name %>
</div>
<div class="field">
<%= f.label :description %><br>
<%= f.text_field :description %>
</div>
<%= f.fields_for :tasks do |task| %>
<%= render 'task_fields', :f => task %>
<%= link_to_add_association 'Add task', f, :tasks, class: "links" %>
<% end %>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
Now here's my views/projects/_task_fields.html.erb file:
<div id="nested-fields">
<div class="field">
<%= f.label :description %><br>
<%= f.text_field :description %>
</div>
<div class="field">
<%= f.label :description %><br>
<%= f.text_field :description %>
</div>
<%= link_to_remove_association 'remove task', f %>
</div>
Is this not exactly what the guide mentions? When I go to create a new project, it shows nothing but the default Name label, name text box, description label, description textbox, and the "create project link". Here's the HTML output of the new project form:
<!DOCTYPE html>

Can someone please assist me with this? It looks like I'm doing everything as mentioned in the guide, and I'm not getting anything out of this.
The link_to_add_association should be located outside the fields_for tag, whatever is inside it will be replicated for each task added and you generally only want a link to add at the end, also nothing shows because no task is instantiated, in order to instantiate one you either click the link_to_add_association or instantiate them on the projects form creation, this can be done at the projects controller new action by doing
#projects_controller.rb
def new
#project = Project.new
#projet.tasks.build
end
You can also instantiate multiple tasks on form creation here by doing some loop like
3.times do
#project.tasks.build
end
How do I add a custom type attribute to a javascript_tag helper in Rails?
<%= javascript_tag id: 'entry-template', type: 'text/x-handlebars-template' do %>
<div class="entry">
<h1>{{title}}</h1>
<div class="body">
{{body}}
</div>
</div>
<% end %>
The above returns:
<script id="entry-template" type="text/javascript">
<div class="entry">
<h1>{{title}}</h1>
<div class="body">
{{body}}
</div>
</div>
</script>
The desired output is:
<script id="entry-template" type="text/x-handlebars-template">
<div class="entry">
<h1>{{title}}</h1>
<div class="body">
{{body}}
</div>
</div>
</script>
javascript_tag is for, um, JavaScript, it says so right in the name. If you want to use a <script> as a container for something that isn't JavaScript, just write it by hand:
<script id="entry-template" type="text/x-handlebars-template">
alert('All is not good');
</script>
or, if you must use a helper, use content_tag:
<%= content_tag(:script, :id => 'entry-template', :type => 'text/x-handlebars-template') do %>
...
<% end %>
I don't see the point to using content_tag for this though, just seems to over-complicate things.
Try,
<%= javascript_tag :html_options => {id => 'entry-template', :type => 'text/x-handlebars-template'} do %>

May it would work. I have not tried it.
