Closing Flash Notice Causes page to redirect - ruby-on-rails

I am following the tutorial for devise and cancan integration for rails.
https://github.com/RailsApps/rails3-bootstrap-devise-cancan
I notice when a user logs in the flash notice causes the page to reload after it has been closed out.
I see this in my logs: Redirected to "the root path" Completed 302
here is my routes file
App::Application.routes.draw do
resources :videos do
collection do
post "delete_selected_item"
end
end
unauthenticated do
root :to => 'external#index'
match '/features' => 'external#features'
match '/pricing' => 'external#pricing'
end
devise_scope :user do
match '/sign_up' => 'devise/registrations#new'
match '/sign_in' => 'devise/sessions#new'
end
devise_for :users
authenticated :user do
root :to => "dashboard#index"
match 'dashboard/videos' => 'videos#index'
match 'dashboard/statistics' => 'statistics#index'
match 'dashboard/analytics' => 'analytics#index'
resources :users
end
post "zencoder-callback" => "zencoder_callback#create", :as => "zencoder_callback"
end

Do you shure that you correctly include bootstrap javascript files?
In application.js should be that line:
//= require bootstrap


Change this
<a class="close" data-dismiss="alert" href="">x</a>
to this
<a class="close" data-dismiss="alert" href="#">x</a>
Now, the page will no longer redirect to root url.
[edit]
an empty href="" in <a> tag reloads the page. so, you can change it to the following:
href="#" adds an extra entry to the browser history (which is annoying when e.g. back-buttoning).
href="javascript:;" does not seem to have any problems (other than looking messy and meaningless)

How to give active class to categories in application.html.erb?

Google maps autocomplete js is working on localhost but not on heroku

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.

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.

Navbar not showing up in Rails Website

I am putting together a basic website from One Month Rails and can't seem to figure out how to get the navigation bar to show at the top. I have spent a few hours and would like to go to the community. Here is the code from the _header.html.erb (using bootstrap sass)
<div class="navbar navbar">
<div class="navbar-inner">
<div class="container">
<a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</a>
<a class="brand" href="#">Project name</a>
<div class="nav-collapse collapse">
<ul class="nav">
<li>
<%= link_to 'Home', root_path %>
</li>
<li>
<%= link_to 'About', about_path %>
</li>
</ul>
<ul class="nav pull-right">
<li><%= link_to 'Login', '#' %></li>
</ul>
</div>
</div>
</div>
</div>
Here is the code from the application.html.erb tab:
<!DOCTYPE html>
<html>
<head>
<body>
<title>One Month Rails</title>
<%= stylesheet_link_tag "application", :media => "all" %>
<%= javascript_include_tag "application" %>
<%= csrf_meta_tags %>
<%= tag :meta, name: "viewport", content: "width=device-width, initial-scale=1.0" %>
</head>
<body>
<%= render 'layouts/header' %>
<div class="container">
<%= yield %>
<%= render 'layouts/footer' %>
</div>
</body>
</html>

You seem to have some HTML errors in application.html.erb. But most modern browsers will fix those errors for you when loading the page. Here's a better version:
<!DOCTYPE html>
<html>
<head>
<title>One Month Rails</title>
<%= stylesheet_link_tag "application", :media => "all" %>
<%= javascript_include_tag "application" %>
<%= csrf_meta_tags %>
<%= tag :meta, name: "viewport", content: "width=device-width, initial-scale=1.0" %>
</head>
<body>
<%= render 'layouts/header' %>
<div class="container">
<%= yield %>
<%= render 'layouts/footer' %>
</div>
</body>
</html>
You should also make sure your _header.html.erb is in app/views/layouts/.
Finally, don't forget to add bootstrap's css file to app/assets/stylesheets/.

I am using gmap4rails on jQueryMobile but the map is not showing when I'm doing a redirecting to the page showing the map. The map shows normally when I refresh the map page, but not when I redirect to the page showing the page. Does anyone have an idea why? Thanks! Below is the code
/app/views/items/map.html.erb
<div data-role="header">
<h1>Market</h1>
<%= link_to 'Sell/Buy', new_item_path, "data-icon" => "plus", "class" => "ui-btn-right" %>
<%= link_to 'Back', root_path, "class" => "ui-btn-left" %>
</div>
<div class="center-wrapper">
<div data-role="controlgroup" data-type="horizontal">
List
Map
</div>
</div>
<div data-role="content">
<%= gmaps4rails(#json) %>
</div>
/app/views/layouts/application.html.erb
<!DOCTYPE html>
<html>
<head>
<title>Project</title>
<%= stylesheet_link_tag "application", :media => "all" %>
<link rel="stylesheet"
href="http://code.jquery.com/mobile/1.3.1/jquery.mobile-1.3.1.min.css" />
<%= javascript_include_tag "application" %>
<script src="http://code.jquery.com/mobile/1.3.1/jquery.mobile-1.3.1.min.js"></script>
<meta name="viewport" content="initial-scale=1, maximum-scale=1">
<%= csrf_meta_tag %>
</head>
<body>
<div data-role="page">
<%= yield %>
<%= yield :scripts %>
</div>
</body>
</html>
/config/routes.rb
ProjectZ::Application.routes.draw do
...
match '/map', to: 'items#map'
end

Rails: how to output pretty html?

I use SASS as views engine with built-in prettyfying option in config/application.rb:
Slim::Engine.set_default_options :pretty => true
Nevertheless, not only usage of rdiscount for posts rendering breaks all that beauty, but typical commands do that, e.g.:
title
= "#{t "title.main"} - #{(yield :title) || "#{t "title.default"}"}"
== stylesheet_link_tag "application", :media => "all"
turns into
<title>Some title</title><link href="/assets/application.css?body=1" media="all" rel="stylesheet" type="text/css" />
In additon, some examples of tags indentation:
<body>
<header>
<h1>...
</header>
<div class="content"><div class="posts"><article>
<div class="title">
<h3>...</h3>
<h2>...</h2>
</div>
<div class="entry"><p>...</p>
<p>...</p>
</div>
</article><article>
<div class="title">
<h3>...</h3>
<h2>...</h2>
</div>
<div class="entry"><p>...</p>
<p>...</p>
</div>
</article><article>
Maybe there is some after_filter or whatever exist to prettify responce.body after all?
That :pretty => true will be disabled then because it does only a half of the work.
