When creating a new Rails application, it is automatically supplied with several quite large js files. In the application layout, by default, all of them are loaded into the page:
<%= javascript_include_tag :defaults %>
I was wondering, isn't loading all those javascripts can make the site possibly mush slower?
And if so, where can I change the definition of :defaults? Or should I just include the ones I need and remove the code line mentioned above?
Thank you
My application is suppose to constantly update the page without any user interaction. The criteria is that the page just has to be there, as an extra window on the monitor so the user can see the information get updated real time.
I'm using the Ajax in jQuery with Rails, and my question is - how long will the .erb page keep Ajax open? Will there be a point where I have to refresh the page or re-initialize? Or will that won't be a problem at all?
Rails routes are great for matching RESTful style '/' separated bits of a URL, but can I match query parameters in a map.connect config. I want different controllers/actions to be invoked depending on the presence of a parameter after the '?'.
I was trying something like this...
map.connect "api/my/path?apple=:applecode", :controller = 'apples_controller', :action = 'my_action'
map.connect "api/my/path?banana=:bananacode", :controller = 'bananas_controller', :action = 'my_action'
For routing purposes I don't care about the value of the parameter, as long as it is available to the controller in the 'params' hash
I have a Post Class and a Comment Class. I have a post object and want to convert it to a Comment object. I went through Rails api and found becomes(klass).For now there is not association between a Post and Comment. So i tried
@post.becomes(Comment).
but becomes method could not be found for @post object. Am i missing something ?
I am a windows developer currently getting into Rails. While you can develop on RoR Windows, it's not the ideal experience. Things are glitchy and running cucumber tests are painfully slow.
So, would I be able to have a decent dev experience running Linux in a VM for doing RoR development, or should I bite the bullet and just do a dual boot - Windows 7 / Linux?
What is the best way to allow for the adding of images and embedding of video in the body:text field of a Ruby on Rails blog.
I understand that I can use an attachment like Paperclip to add a photo to a record but I am wondering how to get images/vids into the actual body of the post.
Hi,
I have a small question regarding rails. I have a search controller which searches for a name in database, if found shows the details about it or else I am redirecting to the new name page. Is there anyway after redirection that the name searched for to automatically appear in the new form page?
Thanks in advance.
Does anyone know of a full featured survey tool for rails? Like Limesurvey (PHP -unfortunately for my purposes.)? Tried to look on Ruby-toolbox, but it seems to be down.
I'm new to Rails and feeling my way, but this has me stumped.
I moved some constants to a separate module ie:
module Fns
Fclick = "function() { alert(\"You clicked the map.\");}\n"
...
end
then in my controller added:
require "fns"
class GeomapController < ApplicationController
def index
fstring = Fns::Fclick
...
end
but when I run the server I get:
uninitialized constant Fns::Fclick
what am I missing?
I have a string like this:
"foo=bar&bar=foo&hello=hi"
Does Ruby on Rails provide methods to parse this as if it is a querystring, so I get a hash like this:
{
:foo => "bar",
:bar => "foo",
:hello => "hi"
}
Or must I write it myself?
EDIT
Please note that the string above is not a real querystring from a URL, but rather a string stored in a cookie from Facebook Connect.
Is there any way in a Rails STI situation to through an error when the base class is Instantiated? Overriding initialize will do it but then that gets trickled down to the subclasses.
Thanks
Hi,
I am trying to move a development environment from production to my local machine (Ubuntu), and when I get the code up and running on my box, the site works in rails but I get this JS error:
Permission denied for http://ad.doubleclick.net to call method Location.toString on http://localhost:3000.
Line 0
Do you have any idea how to fix JS problems, or should I disable the ads in development?
I have a Rails forum product that resides under the subdomains of my customers (i.e. http://forum.customer.com). Their main site has a CMS and an authentication system, and my forum product has a separate authentication system. Is there an elegant way to have "cross-signins" across these systems? I want someone already logged into the main CMS to seamlessly (as possible) transition into my product.
I want to run a paperclip method on create only
has_attached_file :file
This method doesn't seem to accept the :on = :create that some other rails methods do.
I tried:
before_create
after_create
etc, but those didn't work.
I also did:
if :create
How can I test if the controller is using the create method from the model?
Thanks!
Apache keeps serving up my Rails files with a Content-Type of 'text/plain' in the header. I have mod_mime installed, a mime.types files with all the correct MIME assignments, and the following code in my configuration. Any thoughts?
DefaultType text/plain
<IfModule mime_module>
TypesConfig /etc/apache2/mime.types
AddType application/x-compress .Z
AddType application/x-gzip .gz .tgz
</IfModule>
Hi,
I'm trying to redirect from one controller to another in Rails and I am getting this error:
undefined method `call' for nil:NilClass
The code is pretty simple (in def create method):
@blog_post_comment = BlogPostComment.new(params[:blog_post_comment])
respond_to do |format|
if @blog_post_comment.save
flash[:notice] = 'Comment was successfully created.'
redirect_to(@blog_post_comment.blog_post)
else
render :action => "new"
end
end
Save goes ok, the value gets into the database. How can I work around the redirect fail?
Is Rails 3 ready to use in Production?
I know is in beta (currently beta 3), but is it suitable to build a simple app using authentication (devise)? Or should I wait for a final version?
What is your opinion?
Thanks
I have a simple Ruby on Rails form which includes an authenticity_token. Unfortunatly, I missed that when you page cache this page then the Authenticity Token becomes invalid. I'm glad I figured it out however.
How do you solve caching in such a case?
I recently played with MongoDB in Rails using Mongoid. I like the ability to define attributes for models within the model file (as opposed to in migrations):
class Person
include Mongoid::Document
field :name, :type => String
field :birthday, :type => Date
end
For projects that cannot use a schema-less database, does a similar feature exist? Any gems or plugins that generate schemas from a similar syntax would be greatly appreciated.
Thanks.
