Ruby on Rails - Show the same modal with different content - ruby-on-rails

I have a home page with a list of software in a table.
With this link I open my softwares pages in modals:
<% = link_to software_path (software), remote: true do %> ... <% end%>
I created a script allowing me to open my modals when I click on td with class .clickable and not open modals when I click on a td with class .no-click.
$(".clickable").click(function(e) {
if (!$(e.target).hasClass('no-click')) {
$('#software-modal').modal('show');
}
});
structure :
_software.html.erb open _software_modal.html.erb
Problem:
When I try to open my modals via the script, it's always the same modal that opens. That is, the modal of software 1 opens when I click on software 2, software 3, ... but no problem when I just use the link.
So I have a problem with id or something like that in my script ...
Can you help me ?
EDIT 1: With the response of VAD I tried to search the id with data-id.
_software.html.erb
<tr class="clickable" data-id="<%= software.id %>">
...
</tr>
<div id='software-content'></div>
_software_modal.html.erb
<div id="software-modal" class="modal fade" role="dialog">
...
</div>
show.js.erb
$('#software-content').html("<%= j render 'software_modal', software: #software %>");
$('#software-modal').modal('show');
this show.js.erb allows me to open my modals via example links:
<%= link_to software.name, software_path(software), remote: true,class:"no-click" %>
but not via a clickable table.
So I added a script in _software.html.erb that makes my table clickable:
$(".clickable[data-id]").click(function(e) {
if (!$(e.target).hasClass('no-click')) {
window.location = '/softwares/' + $(this).attr('data-id');
}
});
I also tried with data-link, ... is there a way to open this window.location in a modal (like the link)? I searched for several hours yesterday but I did not find anything ..
EDIT 2
following the response of #VAD with render layout: false, we can put:
class ApplicationController < ActionController::Base
   layout proc{|c| c.request.xhr? ? false : "application" }
end
which allows to have a false render for the js and true render for html. And so to keep my html pages with my starting layout.
Thx #dogenpunk
Render without layout when format is JS (needs drying)

You need to have different modals for every place you want to show the modal from. Like for software1 you need to show the modal with content relative to this particular object. For software2 you'll need to show the same model but with a brand new content relative to software2
Another option (and the better one) is that you may have one single modal for every Software object but by some event (for example actually showing the modal) you'll update the modal content with the data specific for this particular Software object. You may use some controller action for that
Additional
Try to pass software id as data parameters in your clickable elements and then to update your modal content with ajax and like that
<div class = 'clickable' data-id = "#{software.id}">
</div>
$(".clickable").click(function(e) {
if (!$(e.target).hasClass('no-click')) {
$.get('/softwares/' + $(this).attr('data_id'), function(data) {
$('#software-modal body').html(data);
});
$('#software-modal').modal('show');
}
});
Of course I can't give precise code so you'll need to adjust it according to you current setup
Update
The idea is that you have show action in softwares_controller.rb which eventually renders the content for your modals:
def show
// some code you need
render layout: false
end
It will render show.html.erb view. In that view you should keep the html for your modal content. Notice that the action will render that view without layout. You need this because you will soon take this html and will put it into the modal, so you don't need any extra html like the layout.
So, you have an action which render the modal content for every software object by its id.
Now you need to put it into the modal.
You have clickable elements in your markup. You attach correspondent software ids to them as data-id. Then in your jquery code you use these ids to construct a url like this:
'/softwares/' + $(this).attr('data_id')
This url will lead to your show action in softwares_controller.rb. So by clicking on one of clickable elements you take the id, generate the url with it, send request to the url, get the response (the modal content) and then put it into the modal like this:
$.get('/softwares/' + $(this).attr('data_id'), function(data) {
$('#software-modal body').html(data);
});
Then you show the modal with already updated content:
$('#software-modal').modal('show');

How to render each views without reloading in rails?

I have a problematic to render my views in my rails app.
I try to create a home page who load each tools of my app (5 - 6 different) but I want to allow users to call them one by one and without reloading the page (like some saas apps).
I tried with a welcome/index.html.erb page that render each views with ajax:
<button class="button1"></button>
<button class="button2"></button>
<button class="button3"></button>
<%= render "tools1/index %>
<%= render "tools2/index %>
<%= render "tools3/index %>
...
How could I do to show only tools 1 if the user click on button1, and then hide tools1 and show tools2 when the user click on button2, etc. ?
Another question, is it an efficient way to do that ?
Edit:
My fault, it wasn't clear. The point is that I don't want to render each page at the beginning, the perfect stuff will be to load (not just show) them page by page, just when the user call them
Thanks
A quick AJAX loader example
Add some links/buttons to your HTML:
<a class="ajax-load" href="/url1">Page 1</a>
<a class="ajax-load" href="/url2">Page 2</a>
<a class="ajax-load" href="/url3">Page 3</a>
<div class="ajax-content"></div>
Add this jQuery code:
$(document).ready(function(){
$('.ajax-load').on('click', function(e){
e.preventDefault();
$('.ajax-content').load($(this).attr('href'));
});
});
Now, when users click on any link, the content will be AJAX loaded.
Previous answer
Since you are rendering your pages in your view, you don't need to ajax load them again. I would suggest using some jQuery plugins to do this for you.
For example: tabs or accordion.

Using devise gem, how does it prefill form values in the edit form and how can this be replicated elsewhere?

I am attempting to place the sign in, sign up and edit forms (from devise) into Bootstrap modals using partials. I have successfully done this by creating partials for the forms (wrapped in the modal code) and rendering them in application.html.erb as follows:
<%= render 'articles/sign_up_modal' %>
<%= render 'articles/sign_in_modal' %>
<%= render 'articles/edit_profile_modal' %>
At the top of application.html.erb I have:
<script type="text/javascript"> $(function () { $("#sign_up").modal({show:false });</script>
<script type="text/javascript"> $(function () { $("#sign_in").modal({show:false });</script>
<script type="text/javascript"> $(function () { $("#edit_profile").modal({show:false });</script>
Where "sign_up", "sign_in" and "edit_profile" represent the id's of the modals from the partials. The modal is then displayed by clicking a button in the _header.html.erb partial:
<%= link_to '<button type="button" class="btn btn-primary">Edit Profile</button>'.html_safe, "#edit_profile", "data-toggle" => "modal" %>
Everything works great except the Edit Profile modal form does not prefill the form with the appropriate values unless I am also on the edit page when I click the button to display the modal. How can I get the Edit Profile modal form to prefill the users data no matter which page they are on in the background?
Does this make sense? Please tell me how I might clarify my question. Thanks!
The answer was provided to me by u/alec5216 on reddit.
He said:
Take a look at the devise source.
https://github.com/plataformatec/devise/blob/master/app/views/devise/registrations/edit.html.erb
You'll see the form is bound to the "resource" variable which is going to be an instance of a user model. I bet if you use current_user in the partial instead of resource you'll have the desired effect.
This worked. See HERE for the full conversation.
In this case you will probably have to make an AJAX call to fetch the required data.
The data itself can either be JSON (for client-side rendering) or the complete html form rendered with the layout: false option. I usually go for the former because it is faster and easier to implement, unless your project is a single-page js application.
You can find more information on bootstrap ajax modals here on StackOverflow.

rails controller action not being called

The problem I'm running into deals with rendering a partial. I basically have a link which should get updated after the user puts some text in a text field. The first time it works fine. The user types in the text, the link gets updated and then when the link is clicked the partial is rendered with the correct information. However when the text is changed the link also gets update with the new parameters to pass to the action but when the link is clicked it still renders the old partial and no call to the corresponding action is made. Here is my view code:
label.control-label for="color_servers" Colors
.controls
input.input-xxlarge type="text" name="colors" id="project_colors" placeholder="comma separated colors" onblur="getColors(this)"
a data-toggle="modal" id="color_target" href="#" data-target="#color_modal" (Show colors)
.modal.hide#color_modal
.modal-header
button.close type="button" data-dismiss="modal" aria-hidden="true" ×
h3 Color list
.modal-body
.modal-footer
a.btn href="#" data-dismiss="modal" aria-hidden="true" Close
And this is my partial which I am rendering:
ul
- for color in #colors
li #{color}
I'm displaying the partial with the information in a lightbox type display. Here is my javascript code for the onBlur event of the text field:
function getColors(elem){
if(elem.value.trim()){
$.ajax({
url: "/project/check_colors",
type: "GET",
dataType: "json",
data:{
colors: elem.value
},
success: function(data){
$('#color_target').attr('href','/project/show_colors?colors=' + data.color_list)
console.log(document.getElementById("color_target").href)
console.log(data.input)
console.log(data.color_list)
}
});
}
}
So in the javascript code when I look at the output of the href attribute in the console, it shows the correct link. And finally here is my controller code:
def check_colors
colors = params[:colors].gsub(/\s+/, "").gsub(/,+/,",")
colors = colors.chomp(",")
color_list = Color.expand_colorset(colors).map(&:fullname)
render 'index', :json => {
:servers => color_list,
:input => colors
}
end
def show_colors
colors_string = params[:colors]
#colors = colors_string.split(",")
puts #colors
render partial: 'color_list'
end
The color_list variable is an array of colors which I send back in order to update the link with. I know that the show_colors action gets called called the first time because the #colors variable's value is printed in my terminal however when I update the text in the textfield and I click on the link again the action is not being called even though the link gets updated because nothing is printed in the terminal. It seems as if the partial is being cached, if that is the problem how can I prevent that. Also when I try to render my partial as a full fledged view rather than a partial, the action is called correctly every time and it renders the correct information even after changing the text field contents, but when I do that then my lightbox functionality does not work correctly. Any help will be appreciated, thank you.
hi guys for anyone who is interested I figured it out. It is kind of hacky but it works for me. I added this piece of code in my javascript outside of all functions, and it cleared the cached ajax.
$('body').on('hidden', '.modal', function(){$(this).removeData('modal');});
Hopefully it will save someone time in the future.

How can i integrate Bootstrap-WYSIWYG in my Rails app?

There is a pretty bootstrap editor - Bootstrap WYSIWYG, which i want to use in my blog based on RoR 4.0. The problem is that Bootstrap WYSIWYG does not work with anything except DIV tag (as far as i know from a bit searching).
This code works fine:
<div id="editor" contenteditable="true">some editable content</div>
And this one doesnt:
<%= f.text_area :content, id: "editor", contenteditable: "true" %>
<textarea id="editor" contenteditable="true">
So, the question is - how to connect this two things together?
have you tried putting a hidden field, working with the div and when the editor have changes update the hidden field value? Hope this helps
In order to integrate Bootstrap-WYSIWYG in a Ruby on Rails app you should do the following:
(most of the times - you have more than one editor in a rails form, in this example I will show how to do it without errors)
I will use the editor in the admin namespace, therefore I have created a folder editor inside my views: "admin/shared/editor" to keep everything tide and content oriented.
Firstly, for every attribute of a model I would like to use the Bootstrap WYSIWYG editor I will render a partial with the field that has integrated the editor, so you might have smth like this:
/admin/posts/_form.html.haml:
= form_for #post do |f|
= render partial: 'admin/shared/editor/field', locals: { f: f, content: "summary" }
= f.button class: "form_with_editor"
were you pass as a local parameter the form and the attribute of the model you would like to apply the editor (in this case => summary). Note also that you should add a class to the submit button of the form: .form_with_editor, that will be used later for the button click listener.
Now inside admin/shared/editor/_field.html.haml:
.btn-toolbar.btn-editor{"data-role" => "editor-toolbar", "data-target" => "#editor_area_for_#{content}"}
= render partial: 'admin/shared/editor/toolbar'
.wysiwyg{id: "editor_area_for_#{content}", style: "overflow:auto; height:444px;max-height:444px", data: {"for-content" => "hidden_#{content}"}}
= f.hidden_field content.to_sym, id: "hidden_#{content}"
This editor works with a div and not with a textarea, therefore, we will be using a div with class .wysiwyg and a dynamic id which in this case evaluates to: #editor_area_for_summary
The class: .wysiwyg is used in order to select all the divs with this class when we initialize the editor in our doc ready function.
The toolbar partial contains all the markup for the custom toolbar of the editor, you can customize it as you wish and use it in all your fields.
In order to copy the contents of the div to the form input and post them to the server, you have to use a hidden input field:
= f.hidden_field content.to_sym, id: "hidden_#{content}"
Note: it also gets a dynamic id(which evaluates to: "hidden_summary") and a name -> :summary
Now in order to make all these to work together we need some javascript on your doc ready function:
/assets/javascripts/doc_ready.js:
$( document ).ready(function() {
// EDITOR stuff
$('.wysiwyg').wysiwyg();
// Handling the form submission
$('.form_with_editor').click(function(){
$('.wysiwyg').each(function() {
var editor_div_content = $(this).html();
var hidden_input = $(this).attr("data-for-content");
$("#" + hidden_input).val(editor_div_content);
});
});
// Fill the editor divs with content
$('.wysiwyg').each(function() {
var hidden_input = $(this).attr("data-for-content");
var editor_div_content = $("#" + hidden_input).val();
$(this).html(editor_div_content);
});
});
On the first part we apply the function wysiwyg() of the editor in every div that has this class.
On the second part we have an on click handler of the form button we get the html content of the div and we set it as the value of our hidden input field.
And on the last part we do the opposite, we get the value of the hidden field and place it on the editors div when the document is ready, with this one we display content on the editor that is already stored in the database.
I hope this one helps :)

how to close view template in Rails 3

I have opened the view template as popup by using the following code:
<%= link_to 'New User', "/users/new", :method => :get, :target => "_blank" %>
controller code:
def new
render :layout => false
end
the new.html.erb is having few textboxes and buttons as Save and Cancel
My problem is how can i close the popup upon clicking Save or Cancel button?
Thank u,
Sudhir C.N.
This a more a javascript question rather than one specific to Rails.
Your Cancel button is easy enough, something like:
<html>
<script>
function CloseWindow() {
ww = window.open(window.location, "_self");
ww.close();
}
</script>
<button type="button" onclick="CloseWindow();">Cancel</button>
</html>
(stolen from http://snippets.dzone.com/posts/show/267)
Your submit button shouldn't change. It will need to POST to your controller as normal. The successful response rendered by the controller should display a "Success" message in the flash and could then close the window automatically after, say, three seconds:
<script>
setTimeout( function() { CloseWindow(); }, 3000);
</script>
This is a pretty simple solution. Maybe consider investigating some popup libraries for either prototype or jquery (depending on the library you're using). Not sure whether modern popup blockers render these D.O.A. though. Your target="_blank" approach should play nice with popup blockers.
Edit: if you're using jquery maybe consider something like the modal dialog: http://jqueryui.com/demos/dialog/#modal-form
You will need to do it with javascript. After the user saves you can respond with another view that sends this:
<script type="text/javascript">
window.close();
</script>
