similar to: custom form builder

Hello, I''m writting some helper methods to write forms, so I have this working code: class TableFormBuilder < ActionView::Helpers::FormBuilder ["file_field", "password_field", "text_field"].each do |name| define_method(name) do |label, *args| @template.content_tag(:tr, @template.content_tag(:td, @template.content_tag(:label,

hello, I want to make a table within a form by making a new form_tag. The following code in ApplicationHelper fails: def tabular_form_for(name, object = nil, options = nil, &proc) concat("<table>", proc.binding) form_for(name, object, (options||{}).merge(:builder => TabularFormBuilder), &proc) concat("</table>",

Hi, I''m writing my own FormBuilder and I wanted to put an asterisk or something next to any required fields. The Builder has access to the AR object, is there any method I can call on the AR object that will tell me whether or not a particular field is required? Failing that, can I access the complete list of validations so I can look through it for instances of

In the example below, what is the dash doing between the class attribute and array: (field_helpers - [:label, :check_box, :radio_button, :fields_for, :hidden_field, :file_field]).each do |selector| -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hi, I want to extend formbuilder to make it output a lable (I know about labeled_form_helper made by technoweenie), my own formating, and a couple of extra tags inside the form attribute. I was easily able to extend form_remote_to. But when I continue to adjust the way elements are handled I don''t know how to continue. I can''t find the method text_field thats should is

Is it possible to pass this FormBuilder object to a controller and then back to a partial? I have a form rendering a partial that i would like to update with a call to my controller based on user selectable parameters, but when the AJAX comes back, i get this error message because i cannot pass a form builder object between the controller and the view: "undefined method

I don''t have a blog, but wanted to share this little bit of code with other semi-beginners like myself who are still learning to take advantage of rails features. Selecting an attribute with a boolean switch is a common pattern in forms. You can do it with a check box, but radio buttons are more expressive in some situations and better convey to the user that they are making a mandatory

Hi, i have some issues with the default rails error wrapping. It wraps errors in a div with class ''fieldsWithError'', which is not good practice in my eyes. Adding a class ''error'' to the field would be much nicer. My solution to the problem: build your own FormBuilder. Funny enough, i found no (nice) possibility to switch error wrapping off while using the

i''m having problem with a form_for situation where i''m trying to DRY out the repeated parts of my forms and put them in common/form and render the form elements via another partial in controller_name/_form. Here''s the first form # app/views/common/form <% form_for ... do |f| -%> <%= render :partial => "params[:controller]/form", :object => f

I''m trying to set up and run a new form builder under rails, which lives under the helpers directory, but isn''t really a helper. (Not a module, so doesn''t mix in well) Short of dropping down into a view spec, how do I set up to actually spec the form builder? describe RandomFormBuilder do attr_reader :builder before do @object = mock_model(Foo) @builder =

I’ve been spending a great deal of time chasing this problem. Hopefully someone sees something obvious I’m doing wrong. Basically anytime I try to call fields_for from an RJS file or within a partial in the RJS file, I get the following error. My goal is simply to load a partial into a div. The fields in this partial require fields_for though. And that’s where the problem lies.

Hi, I''ve got a public\images\DownArrow.jpg and app\views\expenses\new.html.erb that want to present this image in the following context: <p> <%= f.label :vendor %><br /> <%= f.text_field :vendor %> <%= f.image "DownArrow.jpg" %> <br> <%= select_tag "test", options_for_select(@current_vendors.collect {

Hi all, I cannot figure out how to correctly use the with_output_buffer helper method (located in ActionView::Helpers::CaptureHelper) inside a custom FormBuilder. Below follows a simplified example. I''m trying to achieve the following behavior in an ERB as suggested in the form_for helper docs in the Rails source: ========== <%= form_for @object, :builder => MyFormBuilder do

Hello there. I am following a tutorial with rails 2.1 and I have come across a problem where <%= f.label :artist_id %><br /> <%= f.select_tag(:artist_id, options_for_select([[''choose one'', '''']] + @artists.collect {|art| [art.name, art.id]}, @album.artist_id)) %> (Old artist info:<%= @album.artist_old%>) gives undefined method

Hi everybody, I needed change field error rendering for some forms created with Rail''s form builder. I found solution by changing ActionView::Base::field_error_ proc to own before form and changing it back after form rendered. I don''t like this solution :) It''s not thread-safe (but it''s not so important, nobody really wants it :), but I don''t like

I''m using the latest trunk of 1.2-ish, and I''m wondering how to do what I want to do. I am using a form_for :builder I wrote, simply called TableFormBuilder after the rails cookbook, and want to be able to present help icons automatically. I want these icons to appear next to form fields I am rendering. For example, I have this method in helpers/table_form_builder.rb: # This

Hello everyone, I am trying to set a default custom form builder. I have defined my form builder class in "lib/mymodule/mybuilder.rb" as: module Mymodule class Mybuilder < ActionView::Helpers::FormBuilder ...... end end Then I am trying to use this custom class in application.rb as config.action_view.default_form_builder = Mymodule::Mybuilder. But I get "Uninitialized

Aloha all, I love using ggplot. It took a while to get used to the grammar of graphics, but it is starting to get easy now that I am thinking in a more structured way. A question. I'm making a wind rose that I'd like to be oriented with due north straight up. I've discovered that the orientation is sensitive to how north is represented. When north is represented as 0,

I have a page, which renders a partial that contains a ''State'' drop down list. Upon change, it re-renders the ''City'' drop down, re- populating it based on selected state_id: Page: /customer/new.rhtml <% form_for :customer, :url => customers_path do |f| %> State: <%= f.collection_select :state_id, State.find(:all), ''id'',

Am trying to insert a link to delete via ajax in my RJS template.
