When entering log in our rails 3.1 app, ajax is used to render the input screen below. Here is the link for log:
<%= link_to 'Log', new_part_out_log_path(#part, :format => :js), :remote => true, :id => 'new_log_link' %>
And the new.js.erb as this:
$("<%= escape_javascript render(:file => 'out_logs/new.html.erb') %>").insertAfter('#new_log_link');
$('#new_log_link').hide();
$('#close').hide();
the problem is that after clicking 'Log', instead of one view, 2 identical views of out_logs/new.html.erb were rendered. What may be wrong with our code? thank so much.
The problem is related to upgrade to ruby 1.9.3 which causes webrick server (for development) warning message and also rendering the .js.erb file twice on screen. The twice rendering problem disappears on our production server which is running nginx. The following link may help to understand the problem:

What does "WARN Could not determine content-length of response body." mean and how to I get rid of it?

I got a weird problem with my form:
= simple_form_for([#item, #item_comment], :remote => true, id: "new_item_comment", :url => item_item_comments_path(#item)) do |f|
= f.input :comment, :label => false
= f.submit "Save", :class => "btn_save left"
Which in my opinion should call:
Started POST "/de-de/items/20150423/item_comments" for 127.0.0.1 at 2015-04-23 12:29:33 +0200
Processing by ItemCommentsController#create as JSON
but instead I get it as HTML:
Started POST "/de-de/items/20150423/item_comments" for 127.0.0.1 at 2015-04-23 12:29:33 +0200
Processing by ItemCommentsController#create as HTML
It used to work but without changing these parts, it only uses HTML.
Does anyone have an idea on how to solve this?
--- Update 1 ---
I added these lines to my coffeescript:
$('form[data-remote]').submit (e)->
e.preventDefault()
$.rails.handleRemote $('form[data-remote]')
And it works but I'm not really satisfied with this solution since I don't know what caused the problem.
Usually it happened to me in 2 cases:
I had a file input on the form (which forces ruby to skip remote: true option)
I had troubles with jquery-ujs javascript file (which actually processes rails html attrs)
So please check your generated html if it has <form .... data-remote='true'..> and check that jquery-ujs (or whatever handler you want to use) is included in a page javascripts.
If you are still having troubles after this, you can put a breakpoint somewhere in jquery-ujs
For my Rails 4.2 app, my video_tag for HTML5 is working fine for Safari & Chrome, but I get No video with supported format and MIME type found in Firefox.
Here is my view:
<%= video_tag("preroll.webm", "preroll.ogv", "preroll.mp4", controls: true, size: "480x360", poster: "prerollposter.png") %>
Here is my controller show action:
def show
respond_to do |format|
format.any(:html, :m4v, :ogv, :webm) {
}
end
end
Here is my mime_types.rb file:
Mime::Type.register "video/webm", :webm
Mime::Type.register "video/ogg", :ogv
Mime::Type.register "video/mp4", :m4v
In application.html.haml, I have:
%meta{:content => "text/html; charset=UTF-8", "http-equiv" => "Content-Type"}/
In my terminal, I've done...
rake assets:precompile
...and I've continually refreshed my firefox browser and cntl-c'ed out of the local server every time.
I'm new at embedding video into a Rails app, so I'm wondering what the Rails equivalent of .htaccess might be (Is it actually mime_types.rb?).
Any help on this would be much appreciated. I think I'd read somewhere previously that the Rails video_tag has some problems, but I'm not sure if that is the cause of Firefox not working here. Thanks so much!
I'm following the Beginning Rails 3, Updated book from Apress 2010. The problem I'm having is with loading a Template dynamically with Ajax using the jQuery adapter. Everything works but it appears to be rendering three times on the page.
Here is how I dynamically load it when the user clicks the "new comment" link.
views/articles/show.html.erb
<%= link_to "new comment",
new_article_comment_path(#article, :format => :js),
:remote => true,
:id => 'new_comment_link' %>
Then I render it as such.
views/comments/new.js.erb
$("<%= escape_javascript render :file => 'comments/new'," +
" :formats => [:html], :handlers => [:erb] %>")
.insertAfter('#comments');
Then I see this in the log.
Started GET "/articles/1/comments/new.js" for 127.0.0.1 at 2013-01-18 14:51:05 -0600
Processing by CommentsController#new as JS
Parameters: {"article_id"=>"1"}
Article Load (0.2ms) SELECT "articles".* FROM "articles" WHERE "articles"."id" = ? LIMIT 1 [["id", "1"]]
Rendered comments/new.html.erb (53.8ms)
Rendered comments/new.js.erb (54.6ms)
Completed 200 OK in 57ms (Views: 55.9ms | ActiveRecord: 0.2ms)
Notice it renders my erb and the js file? Somehow that ends up with showing up three times on my page.
Any clues on how to fix this? I'm using Rails 3.2.9, rails.js (latest), and jquery-1.9.0.
Thanks!
Solved it!
Turns out I was adding rails.js and jquery.js TWICE!
Here is the skinny: assets/javascripts/application.js is crucial for including javascript files into your app. Basically whatever gets defined there gets pushed out to the page. You simply need to make sure that it gets defined at least once in the app as such.
views/layouts/application.html.erb
<%= javascript_include_tag "application" %>
And that's it! The Ajax jQuery adapter should just work. Becareful not to add any additional files to the javascript folder as those will get pushed out as well and that's exactly what you don't want. Basically I was defining the adapter both through application.html.erb and manually by downloading both files. Hopefully this will help a lost poor soul somewhere along the way.
Happy Hacking.
I'm clueless as to what's going on with this because I have another app on the same server that receives and saves uploads just fine.
No error messages, Paperclip even say's in the log it's saving the attachments.
But the attachments don't get saved.
Thoughts anyone?
Also how would I test for this using RSpec/Capybara, because apparently my tests don't cover this.
Running Paperclip 2.3.12, Rails 3.0.9, REE1.8.7
Production on RHEL5 / Apache , but runs on a different user than my other app's user.
Update I get the same silent fail on development too!
But my test's pass and I can see the image being uploaded with the tests.
I believe you forget to add multipart option to your form
:html => {:multipart => true}
so
<%= form_for #my_object, :html => {:multipart => true} do |f| -%>
...
<% end %>
I'm diving into Ruby on Rails and I'm experiencing a weird bug, using Rails 3.0.1 and Ruby 1.8.7. Using the generated scaffold code, my "Show" action is getting called when I'm expecting my "Destroy" action to get called. Here's the code...
routes.rb
webappdotcom::Application.routes.draw do
resources :projects
root :to => "home#index"
end
index.html.erb
<td><%= link_to 'Destroy', project, :confirm => 'Are you sure?', :method => :delete %></td>
actual HTML code that is rendered in browser
<td>Destroy</td>
server output when I click on the "Destroy" link
Started GET "/projects/12" for 127.0.0.1 at Wed Oct 20 23:39:37 -0500 2010
Processing by ProjectsController#show as HTML
Parameters: {"id"=>"12"}
Project Load (0.1ms) SELECT "projects".* FROM "projects" WHERE ("projects"."id" = 12) LIMIT 1
Rendered projects/show.html.erb within layouts/application (9.0ms)
Completed 200 OK in 77ms (Views: 13.3ms | ActiveRecord: 0.1ms)
You can see the "ProjectsController#show" action is being called, but I want the "Destroy" action to be called. Also, I noticed the browser isn't displaying the confirmation message "Are you sure?" either. Any ideas what could be causing this or what I'm missing?
Thanks so much!
This is because Rails 3 changed the way it uses javascript in forms. It used to add an onclick method to the link, but that goes against unobtrusive javascript. Now it just sets some tag attributes, and hooks into it with javascript in another file.
That page's layout (which is probably application.html.erb unless you've changed it) needs to have this line in the head section:
<%= javascript_include_tag :defaults %>
If this line is missing from your layout, that's the problem. Another possible cause could be if you've added the jQuery library to your app without adding the rails-specific jQuery library. Let me know how this works.
This may help you link_to with :method=>:delete not working ( Rails 3 ). Although in that article the edit is getting called instead. But the solution should work for show as well.
