I want to pass the id from my post to the

Hi there, some time ago there were two posts on this subject on this list: One way that might satisfy the elegence factor is to treat your > comment controller as a component in this case, calling > render_component within your post controller where you need to process > the comment. > > http://manuals.rubyonrails.com/read/chapter/73 > > There are a few ways you could do

I''m having some problems with ActionMailer and I''m hoping that someone can help. I''ve followed the tutorial on "How To Send Emails With Action Mailer" <URL: http://wiki.rubyonrails.com/rails/show/HowToSendEmailsWithActionMailer >, I''ve generated a mailer -- "notifier.rb" -- and I''ve added the following method to the

After I have uploaded my app where do I specify that my app should now use production environment settings and not development? Can that be done dynamically so that I don''t have to reset a value once I upload website? Thanks for your help!

Hi, Maybe I ask again for something what is wasn''t able to find anything. Is there simple way how to process authorizations? My imagine is that some action for controllers are allowed only to few users. E. g. Everybody can look category list, but only registred user can edit or add. In best way, when user is signup, rails will remember his rights like: adding_category = false

hi, I''ve got the following tables in mysql notation: CREATE TABLE `nodes` ( `id` int(11) NOT NULL auto_increment, `parent_id` int(11) default ''0'', `group_id` int(11) default ''0'', PRIMARY KEY (`id`), ); CREATE TABLE `groups` ( `parent_id` int(11) NOT NULL default ''0'', `id` int(11) NOT NULL auto_increment,

Hi everyone, I am relatively new to rspec and I am running into a wall in testing my views. I have a RESTful resource Contracts with a nested resource of Line_items. I am trying to figure out how to test the "edit" form of the Line_items. What complicates this is the nested routing and how to account for it, and that there is a partial form (_form.haml) that both the edit.haml and

I''m attempting to use caches_page to speed up the loading of certain pages on my site, and have run into a couple questions: 1) The site has ''states'' (as in U.S. states), so I have a State model and a States controller. Going to http://sitename/states/ routes you to the States controller, ''index'' action. The States controller looks like so: class

First let me say that Rails caching is very very cool. The traffic (and responsiveness) I''ve saved by added 10 lines of ruby code would be enourmous, if I actually had traffic... ;) Sweepers as observers are great, btw. Since every page of my side is dynamic, once I did some DB optimization I''m caching the content of the index page which was taking the bulk of the time to load

I have added roles and roles_users table and updated the model so that my users can have multiple roles. ("Admin" role does always have id = 1). I have added these methods to my application controller. <code> helper_method :is_admin? helper_method :is_user? def is_admin? if @session[''user''] @session[''user''].roles.find(1)

Hi, I have performed the cookbook tutorial. Before tailoring the views and controllers, when I put in the model recipe.rb: validates_uniqueness_of :title validates_length_of :title, :within => 1...20 And I tried to introduce some new recipe without the above conditions I got the message: --------------------------------------------------- New recipe 1 error prohibited this category from

I am new Ruby on Rails, so excuse me if my question seems pretty obvious. I am trying to validate uniqueness of a filed: class EventType < ActiveRecord::Base belongs_to :sport validates_uniqueness_of :event_type end When I run it, I get this error message: Showing /event_type/new.rhtml where line #27 raised undefined method `each'' for nil:NilClass <select

A couple questions: 1) How does rails no if you are in your test, dev or production environment? 2) Does anyone have an actionMailer server settings that will work on your standard local machine? I will use the one provided for my textdrive account but for testing on my machine I am getting connection refused. Thanks. Your Friend, Jonathan Kopanas http://www.kopanas.com

Here is an example that seems perfect for Ajax that I have not seen implemented nor can figure out how to do it. I am hoping someone can give me some pointers. On the sign-up page, I would like to do my validations (password length, username uniqueness,etc ) Ajax-style. But if all validates, then redirect to the success page. The combining of redirection to a new page with Ajax is throwing me.

Hello, I have a page where user can register him/herself to the site. If the user enters something wrong, or leaves blank textboxes, I want to reload the page and tell the user what went wrong. Also the textbox-values the user already entered, should be kept in the textboxes. For example, in my user-controller: if @username.length == 0 redirect_to :action =>

Hi! If i have an object it''s easy. But i''m making a simple contact form and i check if email address is correct. If it''s not i redisplay the form with the info that there was an error (should i use redirect_to or render :action? what''s the difference?), but all previously submitted data is lost. I tried creating variables using names of the form fields, but

Thanks for the input Blair Zajac and Chris (Nolan and Hall), and for others. If all of you have time, please follow this (the question still relates to the previous posts by me): I have provided full steps to reproduce the symptoms.

It seems odd to me that the layout is processesed after the view. When I set a variable inside the view it does not have an impact on the layout file. But when I set it in the controller it does. Is this the way it works or is it possible that I am doing something wrong?

Hi, I cannot seem to find out how to pass in a value to a partial. Can anyone help me? What I am doing(in the code below) is calling a function in my controller called setobject. This function just redraws the partial. I want to be able to change the value @objectname, redraw my partial and have it be able to use that value. The first the page is drawn it works, but when i call setobject it
