similar to: error_messages_for and seperate controllers

I am trying so learn how to do custom validations. The validation works as expected, but I can''t get "error_messages_for" to display. How is the name of the object supposed to be formated? Where is this object created, the model or controller? What am I doing wrong here? #### Model ######################## class MyFolder < ActiveRecord::Base def validate # validation

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

Greetings, I''m in the throws of deploying an app on site5, and I''m getting strange errors. I think I might need to understand how error_messages_for works.

How would I set up a model stub so that <%= error_messages_for ''some_model'' %> doesn''t complain? I started going down this road: @some_model.stub! (:errors).and_return(ActiveRecord::Errors.new) but it seems like a long, hopefully uneccessary road. Cheers, Michael

Hi, I have this save routine: def customer_address_create customer_options @customer = Customer.find(params[:id]) @customer.addresses.create(params[:address]) @saved = @customer.save end That passes to a rjs template like this: if @saved page.visual_effect :Fold, ''add_address'' page.replace_html ''addresses'', :partial =>

Hi, I wonder why error_messages_for take strings as params instead of instance variables. error_messages_for ''user'' instead of error_messages_for @user ''user'' is translated into @user eventually. If so, who not take the instance variables directly? Is there any reason for that? Thanks in advance. Sam -- Posted via http://www.ruby-forum.com/.

Hi all, I am trying to change the default formatting for the error_messages_for. To quote from the ROR manual: /////////// error_messages_for(object_name, options = {}) Returns a string with a div containing all the error messages for the object located as an instance variable by the name of object_name. This div can be tailored by the following options: header_tag - Used for the header of

Just learning Rails.. So this is probably a noob question. My apologies. Could anyone please give me a quick summary/example on the usage of error_messages_for?

Hi, just a simple question between error_message_on / error_messages_for ... Well, if you use error_messages_for in your web page, there is no problem even if anObject==nil (for example , the first time you load your form) whereas error_message_on must be use with an instanciated object ... So, you always has to double check if anObject is not nil before using error_message_on ? I

Specifically, I have the line: <%= error_messages_for ''user'' %> at the top of one of my .rhtml files and of course a variable @user.
