similar to: Clearing out AR object''s errors array on multiple form posts

All, Trying to upload multiple files. Form: <% index = 0 for @image in images do %> <TR> <TD> <%= @image.path.split(''/'').last[0..39] %>: <% if ((! @image.path.nil?) && (@image.path.length > 40)) %> <%= h("...") %> <% end %> </TD> <TD> <%=

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

All, My apologies if this is a little long-winded and stream of consciousness-y :). SUMMARY: Why do we extend ActiveRecord instead of mixing it in to our model classes? Been thinking about my app''s models and starting to want to build something of a hierarchy. I have some commonality across 3 of my model classes and I''d liek to aggregate the behavior in a superclass.

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

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.

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

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/.

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

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

All, I''m having a hell of a time figuring out what is going on here. I''m trying to override one of my getters so that I can format it a certain way in my form. But I can''t seem to get text_field to call the appropriate method on my object. So here''s my getter: public def FAX fax = read_attribute(:FAX) puts fax

We had an after(:each) callback that looked like this: PurchaseOrder.find(:all).each {|po| DraftInvoice.find_all_by_po_number(po.po_number).each {|di| di.destroy}} which we were hoping would reset some purchase order data in a certain way. However, because we have "self.use_transactional_fixtures = true" set in test_helper.rb, this code was never getting committed. So, I just

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

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

Here is my class: class Document < ActiveRecord::Base public def initialize puts "Called initialize..." super.initialize end This generates the following 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.initialize WTF? Wes -- Posted via

I have an application where I am allowing users to upload (or refer the app. to) arbritrary HTML that I am (currently) displaying in an IFRAME on a page. The users will be authenticated so it''s not open to the entire universe. I was always uneasy with this, but after reading the security chapter of AWDWR, I am even more concerned. What kinds of applications do people have out there

All, This isn''t strictly a problem or issue with RoR but I wondered if someone might have some insight. I have a DIV on a page which I am using to "preview" the contents of a URL provided by the user. Basically, when the user clicks on a link, I do an AJAX call to an action which uses Net::HTTP to request the URL in question and then update the DIVs innerHTML attribute

I had a situation where I wanted to use a <%= %> (scriptlet) in my text_field call to set the "disabled" attribute on the text field, like so: <%= text_field(:current_job, ''removeLinkPos'', :value => '''', :id => ''offset'', :maxlength => 2, :disabled => <%= sometest ? ''true'' :

All, I''ve downloaded and installed a plugin into my vendor directory. How do I then take advantage of it? It has an init.rb file which has the appropriate require. What do I need to do to make sure that the plugin code gets loaded? Thanks, Wes -- Posted via http://www.ruby-forum.com/.

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
