similar to: Validation not executing on save - need help debugging

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 syntax error on line 1.

Here''s a snippet of my model: validates_presence_of :from_name, :from_email, :reply_name, :reply_email, :eSubject protected def validate puts "Calling: #{target_list_ids}" errors.add_to_base("You must choose at least one target list for this job") if self.target_list_ids.nil? end It appears that the validates_presence_of are being called just fine,

All, I''m starting to see view state information creeping into my model class. For example, I have text fields in my view that need to be set a certain way depending on whether or not a checkbox is checked. And while the values of these text fields ultimately do represent database columns that are related to the backing AR object, the text_field values also represent attributes on a

All, I''m finally doing my first real form in Rails - the model object that I''m entering information for has 8 validations so far. If I type in good values for all the fields but one, I get the pretty validation, and the nice field highlighting, but all of the fields are cleared, forcing me to retype all of that info. That is a big drag. Is there a standard way to get the

I have two models bank and country. User should only associate a Bank with a country id present in the country table and I put validates presence of country to enforce it but i get error mysql2::Error: Unknown column ''countries.bank_id'' in ''where clause'': SELECT `countries`.* FROM `countries` WHERE `countries`.`bank_id` = 17 LIMIT 1 when updating the bank

All, I''ve decided to jump into Migrations before I get too far along on the DB side of things. I already have some tables built, and I went ahead and built the migration that would have created them from scratch, and I made sure that there was a self.down section to drop them. I wanted to verify that I could roll back so I figured I would use rake to drop these pre-existing tables

All, In a template, I have <%= text_field :target_list, :DateReceived, { :title => ''uploaded_at'', :class => ''target_list_info'', :disabled => ''true'' } %> Here is the DateReceived method on my

I have some code in my controller which looks like this: if request.post? and @account.save and @user.save ... end and in my Account and User models I have many :validates, like so account.rb validates_presence_of :subdomain, :on => :create validates_uniqueness_of :subdomain, :on => :create, :message => "is already being used" validates_exclusion_of

I don''t want to put certain code in my controller because I think it makes things more confusing. What is the best way to manage business logic such that it doesn''t end up in the controller? Basically, where should I put my regular utility classes and backing objects that may not be models? Thanks, Wes -- Posted via http://www.ruby-forum.com/.

I am doing an Ajax call in my page to a controller method like so: new Ajax.Request(''<%= url_for(:action => "target_list_add" )%>'', { asynchronous:true });" In my controller method "target_list_add", I do something and then I say: redirect_to( :action => ''target_list_upload'', :layout => false ) I know for certain

Is there a trick to validating select menus? I have this rule: validates_presence_of :title, :type :title is a text box and validates correctly but :type doesn''t: <p> <label for="resource_type">Type</label><br/> <select name="resource[type]" id="resource_type"> <option value=""

Hi, Correct me if I am wrong but there doesn''t seem to be an easy way to add validation outside the pre-built ones (validates_presence_of, validates_lenght_of, etc.). Ideally there should be something like: Class Person < ActiveRecord::Base validates :my_method, :on => create, :message => ''was not valid'' def my_method(param) false unless

All, In JSP, I can output strings in the Web page by either <%= foo %> //foo is a string or returns a string or <% out.write("test") %> //write directly to the output stream. What is the method of "writing to the output stream" in RoR? Basically, what is the equivalent of out.write()? I have an if then statement that I want to put around a call to h

All, I''m building model objects for existing tables that I cannot modify. In AWDWR, Dave says "Note that our join table has no id column...The second reason for not including an id column in the join table is that AR automatically includes all columns from the join tables when accessing rows using it. If the join table included a column called id, its id would overwrite the id

All, I have an ActiveRecord object that I need to be able to uniquely identify _before_ I actually save the object (I may not end up saving the object based on conditions). This is because I want to use the ID in another context (a file name in the filesystem). Depending on conditions, I may or may not need to do a lot of stuff between the time that I generate the object ID and actually

Hi All, View ******** <tr> <td><b>Student: </b></td> <td><%= text_field "student", "fname", "size" => 40, "maxlength" => 40 %></td> </tr> <tr> <td><b>Program: </b></td> <td><select id="student_program_id"

So having just learned how to do has_many :through as opposed to HABTM, and then, being concerned that I wouldn''t get it to work, I started thinking about these two approaches. It seems to me that the _only_ problem that the HM:T (has_many :through) approach solves that HABTM doesn''t is the issue of the potential collision of id columns between your join table and one of

Okay, this is something I run into a lot and don''t really have a great solution. Here is a simple example: class Blog < ActiveRecord::Base has_many :posts validates_presence_of :name end class Post < ActiveRecord::Base belongs_to :blog validates_presence_of :name validates_presence_of :blog_id end Now, if I want to create a blog and post at the same time I

All, I have a left navigation partial that I want to dynamically generate CSS classes for based on the current controller action. In my ERb template, I have <DIV class="<%= get_menu_display_style(''login_form'') %>"> In application.rb, I have the method get_menu_display_style defined as: public def get_menu_display_style(action_requested)

I successfully got rake appdoc to work on the depot application (after manually applying the patch for rake 0.70). Everything appears to generate fine, but I can''t pull up the documentation in my browser. I''ve tried: http://localhost:3000/doc/app/ http://localhost:3000/doc/app/index.html I always get: Recognition failed for "/doc/app/" with
