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. I get a pretty standard looking error: " You have a nil object when you didn''t expect it! You might have expected an instance of ActiveRecord::Base. The error occured while evaluating nil.errors Extracted source (around line #7): 4: 5: <div class="admin_content_row...

...s_presence_of :name" in my comments model. This is the problem I''m facing now. In past examples I''ve looked at, for example when you''ve just scaffolded a page, the page seems to submit back to itself if there''s an error and displays the error using <% error_messages_for ''post'' %> However, the way this seems to be working which is the same method that the "creating a weblog in 15 minutes" video uses, the page will never return to itself and so cannot display the error. It simply says "comment added" and posts not passing...

I am trying to put some smarts around a call to <%= error_messages_for %> so that when I first come into this page i.e. when my instance variable @target_list has not been defined yet, the page doesn''t break. I''m doing this: <% if @target_list? %> <%= error_messages_for ''target_list'' %> <% end %> I get a sy...

I am having trouble getting error_messages_for to work. My controller(relevant parts) looks like def configure @account = session[:account] @user = User.new end def add_new_user_to_account @user = User.new(params[:user]) if @user.valid? session[:account].users << @user end redirect_to :action=>...

I am unable to get a proper error message however. If i use error_messages_for(''address'') it retu...

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...

Hi I''m trying to spec a call to error_messages_for to avoid stubbing out whole models. Something like this: context "A rendered calculate_quote view" do setup do @form = mock("form") assigns[:form] = @form end specify "should render the error messages" do <SOMETHING>.should_receive(:e...

...ach Street already assigned to the Area by using form fields with street[id][name], street[id][num_houses] etc. But when I send the form I don''t know how to get any validation errors reported. Errors on Area are nicely displayed with the red outlines - I think this is thanks to <%= error_messages_for ''area'' %> being included in the view. Can I get this to work for the multiple Street input fields as well? I''ve tried <%= error_messages_for ''street'' %> (You have a nil object when you didn''t expect it! You might have expected an in...

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 test if name == ''test...

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? I have two tables/models, Group and GroupMembers. Obviously, a Group has_many GroupMembers. I have a customized view which shows a list of GroupMembers followed by a field and a button which facilitates adding a member to the group by either email address or login. When the user attempts to ad...

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

Hey All ! I have a form which contains two models. I would like both models to be validated, but have their validations aggregated on the page. If I do: <%= error_messages_for(:model1) %> <%= error_messages_for(:model2) %> It puts two big validation blocks on the page. I would like all the errors from both models, but only in one validation box. Is this possible ? All my attempts have failed thus far :) -------------- next part -------------- An HTML attachme...

Hi all, I am trying to change the default formatting for the error_messages_for.

This div can be tailored by the following options: header_tag - Us...
