I have a form configured with some javascript. The javascript is loaded on load event handled by Turbolink:
//app/assets/javascripts/init.js
var ready = function () {
App.init(); //I configure some components of _form.html.erb partial
};
$(document).ready(ready);
$(document).on('page:load', ready);
If I render a partial the App.init() code is not execute and my application is not well configured.
//new.js.erb
$("#my-modal").html("<%= j( render 'form') %>");
$("#my-modal").modal("show"); //The partial is inside a modal
Can I execute the code after the partial is rendered?
Something like this:
$(document).on('partial:render', ready); //Concept
In need to execute the js code after the partial is render becouse I need to configure some Jquery plugin to customize the modal form.
The modal is a classic Twitter Bootstrap modal:
//_form.html.erb
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
<div class="row">
<div class="col-sm-offset-3 col-sm-9">
<h3 class="modal-title" id="myModalLabel">new</h3>
</div>
</div>
</div>
<%= simple_form_for(...) do |f| %>
<div class="modal-body">
<ul class="errors"></ul>
<%= f.error_notification %>
<%= render "companies/fields", f: f %>
...
...
</div>
<% end %>
</div>
</div>
Try:
$(document).on('page:change', function () {
// Actions to do
});
In your case simpley replacing the 'page:load' line in your js call with:
$(document).on('page:change', ready);

any help?
You need to move the ERB tags outwards so that you actually call escape_javascript:
document.querySelector("#pay_invoice").insertAdjacentHTML(
"afterbegin",
"<%= escape_javascript(render partial: 'pay', locals: { event: #event }) %>"
);
The reason you are getting a syntax error is that you're outputting the partial unescaped and it contains at least one double quote which ends the string.
I'm having with populating the bootstrap 4 modal with a show action for a clickable image link. I'm currently using Carrierwave for uploading images. At this point, when I click the image, only the modal overlay displays. The modal container with content inside of it, doesn't show at all.

Since you dont have any instance variable #post defined on _posts partial and still trying to call it within _posts, its throwing up error.
The approach to solve this issue if you want to use Bootstrap Modal without extra js script is to bring _post partial code to _posts partial itself and <% end %> the loop after modal.
<% #post_items.each do |post| %>
<%= link_to image_tag........................
<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close">

<h4 class="modal-title" id="myModalLabel">Post Show</h4>
</div>
<div class="modal-body">
# complete partial code goes here
</div>
</div>
</div>
</div>
<% end %>
Obviously above approach is not good for performance as it will render everything without the need for it.
Better approach is to use Ajax using jQuery (my preference). listen for this button event (onClick) and load modal on the fly using ajax get method. consider looking at this approach for better performance reasons.
The second solution i am talking about is well explained here: https://stackoverflow.com/a/22144587/2545197
Maybe something like this?
In your JS
var $modal = $('#ajax-modal');
$.fn.modalmanager.defaults.backdropLimit = 1;
$('.modal-link').on('click', function(){
var modal_url = $(this).data("modal-url");
if(modal_url != null){
// create the backdrop and wait for next modal to be triggered
$('body').modalmanager('loading');
$modal.empty().load(modal_url, '', function(){
$modal.modal();
// Any callback functions such as let's say selectpicker
// $('#ajax-modal .selectpicker').selectpicker('refresh');
});
return false;
}
});
and in ERB
<%= link_to 'Show', post_path(#post), class: 'modal-link', data: { modal_url: post_path(#post) } %>
I solved this problem by simply rendering the file for the modal show view instead of the normal show action.
def show
#post = Post.find(params[:id])
#new_comment = Comment.build_from(#post, current_user.id, "")
respond_to do |format|
format.html {render :file => "posts/modal", layout: false}
format.js {render :file => "posts/modal", layout: false}
format.json {render json: #post }
end
end
I am trying to use modals in place of the traditional 'show' views in Ruby. When a user clicks on a item in the index view, a modal popup shows instead of redirecting the user to a new 'show' page.
How can I accomplish this?
Let's assume that the controller looks something like this:
#list = Items.all
I want the modal to show the characteristics of each item on the #list object. For instance, one modal would show #list[0] and another would be #list[1]. How can I pass the index values to the modal?
An approach I might take would be, assuming that on your index there is a dropdown and a submit button ...
jQuery
$('#submit').click(function(){
$.ajax({
url: "items/get_item",
type: "GET",
data: { item: $('#select').val() },
success: function (data) {
//Populate modal in here with item details
$('#myModal modal-body').html(data)
}
});
});
Item Controller
def get_item
return :json => Item.where({:name => params[:item]}).to_json
end
View
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">
<span aria-hidden="true">×</span>
<span class="sr-only">Close</span>
</button>
<h4 class="modal-title" id="myModalLabel">Modal title</h4>
</div>
<div class="modal-body"></div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
You need to render a javascript template from the show action
def show
#list = Items.all
respond_to do |format|
format.js { render 'your_js_template' }
end
end
Then in your template you can use the #list instance variable to create the jQuery for the modal
I'm busy learning Rails 4 and I would like to display a bootstrap popup modal when a user clicks on a link, when the modal opens it needs to show the information relating to that particular record.
Heres what I have done so far, which just doesn't show the actual modal popup BUT does pass the correct parameters.
index.html.erb page has:
<%= link_to "view", work_path(w), remote: true, :"data-toggle" => 'modal', :"data-target" => '#myModal' %>
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true"></div>
I also have a works/_modal.html.erb:
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">× </button>
<h4 class="modal-title" id="myModalLabel"></h4>
</div>
<div class="modal-body">
<%= #work.name %>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
also a works controller:
def show
#work = Work.find(params[:id])
if request.xhr?
respond_to do |format|
format.html {render :partial => 'modal'}
format.json {head :ok}
end
end
end
and finally a works/show.js.erb:
$("#myModal").html("<%= escape_javascript(render 'modal') %>");
I hope i'm missing something easy here. in the console I can see the following message so i know it is returning the correct information, but unfortunately it is not showing the modal.:
Started GET "/works/8" for 127.0.0.1 at 2014-03-03 09:31:12 +0000
Processing by WorksController#show as JS
Parameters: {"id"=>"8"}
Work Load (0.2ms) SELECT "works".* FROM "works" WHERE "works"."id" = ? LIMIT 1 [["id", 8]]
Rendered works/_modal.html.erb (4.9ms)
Completed 200 OK in 8ms (Views: 6.3ms | ActiveRecord: 0.2ms)
Any help on this is greatly appreciated.
Have a try with another way. In this way, we are going to show the modal popup using explicit javascript command.
In index.html.erb
<%= link_to "view", work_path(w), remote: true, class: 'static-popup-link'%>
<div class="modal hide fade" id="myModal" tabindex="-1" role="dialog" data-backdrop="static" data-keyboard="false">Loading...</div>
In application.js
$(document).ready(function() {
var clickOnPopupLink = function(){
$('body').on('click', '.static-popup-link', function(){
$('#myModal').modal('show');
});
}
clickOnPopupLink();
});
In controller
def show
#work = Work.find(params[:id])
end
In show.js.erb
$('#myModal').html("<%= j render("/works/modal")%>")
You also need to show the modal, add $('#myModal').modal('show') in show.js.erb
$("#myModal").html("<%= escape_javascript(render 'modal') %>");
$('#myModal').modal('show')
I was looking to using the Twitter Bootstrap Modal windows as a partial view. However, I do not really think that it was designed to be used in this fashion; it seems like it was meant to be used in a fairly static fashion. Nevertheless, I think it'd be cool to be able to use it as a partial view.
So for example, let's say I have a list of Games. Upon clicking on a link for a given game, I'd like to request data from the server and then display information about that game in a modal window "over the top of" the present page.
I've done a little bit of research and found this post which is similar but not quite the same.
Has anyone tried this with success or failure? Anyone have something on jsFiddle or some source they'd be willing to share?
Thanks for your help.
Yes we have done this.
In your Index.cshtml you'll have something like..
<div id='gameModal' class='modal hide fade in' data-url='#Url.Action("GetGameListing")'>
<div id='gameContainer'>
</div>
</div>
<button id='showGame'>Show Game Listing</button>
Then in JS for the same page (inlined or in a separate file you'll have something like this..
$(document).ready(function() {
$('#showGame').click(function() {
var url = $('#gameModal').data('url');
$.get(url, function(data) {
$('#gameContainer').html(data);
$('#gameModal').modal('show');
});
});
});
With a method on your controller that looks like this..
[HttpGet]
public ActionResult GetGameListing()
{
var model = // do whatever you need to get your model
return PartialView(model);
}
You will of course need a view called GetGameListing.cshtml inside of your Views folder..
I do this with mustache.js and templates (you could use any JavaScript templating library).
In my view, I have something like this:
<script type="text/x-mustache-template" id="modalTemplate">
<%Html.RenderPartial("Modal");%>
</script>
...which lets me keep my templates in a partial view called Modal.ascx:
<%# Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %>
<div>
<div class="modal-header">
<a class="close" data-dismiss="modal">×</a>
<h3>{{Name}}</h3>
</div>
<div class="modal-body">
<table class="table table-striped table-condensed">
<tbody>
<tr><td>ID</td><td>{{Id}}</td></tr>
<tr><td>Name</td><td>{{Name}}</td></tr>
</tbody>
</table>
</div>
<div class="modal-footer">
<a class="btn" data-dismiss="modal">Close</a>
</div>
</div>
I create placeholders for each modal in my view:
<%foreach (var item in Model) {%>
<div data-id="<%=Html.Encode(item.Id)%>"
id="modelModal<%=Html.Encode(item.Id)%>"
class="modal hide fade">
</div>
<%}%>
...and make ajax calls with jQuery:
<script type="text/javascript">
var modalTemplate = $("#modalTemplate").html()
$(".modal[data-id]").each(function() {
var $this = $(this)
var id = $this.attr("data-id")
$this.on("show", function() {
if ($this.html()) return
$.ajax({
type: "POST",
url: "<%=Url.Action("SomeAction")%>",
data: { id: id },
success: function(data) {
$this.append(Mustache.to_html(modalTemplate, data))
}
})
})
})
</script>
Then, you just need a trigger somewhere:
<%foreach (var item in Model) {%>
<a data-toggle="modal" href="#modelModal<%=Html.Encode(item.Id)%>">
<%=Html.Encode(item.DutModel.Name)%>
</a>
<%}%>
I have achieved this by using one nice example i have found here.
I have replaced the jquery dialog used in that example with the Twitter Bootstrap Modal windows.
Complete and clear example project
http://www.codeproject.com/Articles/786085/ASP-NET-MVC-List-Editor-with-Bootstrap-Modals
It displays create, edit and delete entity operation modals with bootstrap and also includes code to handle result returned from those entity operations (c#, JSON, javascript)
I use AJAX to do this. You have your partial with your typical twitter modal template html:
<div class="container">
<!-- Modal -->
<div class="modal fade" id="LocationNumberModal" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">
×
</button>
<h4 class="modal-title">
Serial Numbers
</h4>
</div>
<div class="modal-body">
<span id="test"></span>
<p>Some text in the modal.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">
Close
</button>
</div>
</div>
</div>
</div>
</div>
Then you have your controller method, I use JSON and have a custom class that rendors the view to a string. I do this so I can perform multiple ajax updates on the screen with one ajax call. Reference here: Example but you can use an PartialViewResult/ActionResult on return if you are just doing the one call. I will show it using JSON..
And the JSON Method in Controller:
public JsonResult LocationNumberModal(string partNumber = "")
{
//Business Layer/DAL to get information
return Json(new {
LocationModal = ViewUtility.RenderRazorViewToString(this.ControllerContext, "LocationNumberModal.cshtml", new SomeModelObject())
},
JsonRequestBehavior.AllowGet
);
}
And then, in the view using your modal: You can package the AJAX in your partial and call #{Html.RenderPartial... Or you can have a placeholder with a div:
<div id="LocationNumberModalContainer"></div>
then your ajax:
function LocationNumberModal() {
var partNumber = "1234";
var src = '#Url.Action("LocationNumberModal", "Home", new { area = "Part" })'
+ '?partNumber='' + partNumber;
$.ajax({
type: "GET",
url: src,
dataType: "json",
contentType: "application/json; charset=utf-8",
success: function (data) {
$("#LocationNumberModalContainer").html(data.LocationModal);
$('#LocationNumberModal').modal('show');
}
});
};
Then the button to your modal:
<button type="button" id="GetLocBtn" class="btn btn-default" onclick="LocationNumberModal()">Get</button>
Put the modal and javascript into the partial view. Then call the partial view in your page.
This will handle form submission too.
Partial View
<div id="confirmDialog" class="modal fade" data-backdrop="false">
<div class="modal-dialog" data-backdrop="false">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title">Missing Service Order</h4>
</div>
<div class="modal-body">
<p>You have not entered a Service Order. Do you want to continue?</p>
</div>
<div class="modal-footer">
<input id="btnSubmit" type="submit" class="btn btn-primary"
value="Submit" href="javascript:"
onClick="document.getElementById('Coordinate').submit()" />
<button type="button" class="btn btn-default" data-
dismiss="modal">Cancel</button>
</div>
</div>
</div>
</div>
Javascript
<script type="text/javascript" language="javascript">
$(document).ready(function () {
$("#Coordinate").on('submit',
function (e) {
if ($("#ServiceOrder").val() == '') {
e.preventDefault();
$('#confirmDialog').modal('show');
}
});
});
</script>
Then just call your partial inside the form of your page.
Create.cshtml
#using (Html.BeginForm("Edit","Home",FormMethod.Post, new {id ="Coordinate"}))
{
//Form Code
#Html.Partial("ConfirmDialog")
}
