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

In the API docs I found this: "You can also build forms using a customized FormBuilder class. Subclass FormBuilder and override or define some more helpers, then use your custom builder " I couldn''t find any further documentation on this. Where can I read more about this formbuilder class? For starters, where would I define a subclass of this class? TIA, Jeroen --

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

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'',

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.

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 find a good way to emit <label> tags inside a form_for() block, without needing to repeat the name of the instance variable constantly. Is there a better way to do this than the snippet below, or do I need to do a little extension to the FormBuilder itself? <% form_for :long_example_name, @long_example_name, :url => { :action => :new } do

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''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

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

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,

I want to write a spec for a custom form builder, but I''m not really sure where it should live or how to include the right rspec_on_rails contexts. Ideally, I should be able to write a spec like: describe LabelledBuilder do it "should let me create a text field" do object = mock(object) object.stub!(:attribute).and_return("Test String") render

I love form_for, but I really hate <% form_for :person, @person, :url => {...} do |f| %> ... <%= render :partial => ''form'', :locals => {''f'' => f} ... <% end %> I''ve been thinking of instead allowing <% form_for :person, @person, :url => {...} do |f| %> ... <%= f.partial ''form''

I would like to use form_for in my project so that I can easily change the style of many forms at once. However, it seems to me like FormBuilders only support certain kinds of form elements(!). Surely there must be a way to add arbitrary labels/form elements to a form. Let''s say I had a form that looks like: ID: (plain-text label) Name: (text field) Birthdate: (date chooser) Picture: (picture) Foo: (custom widget) How can I use f...

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.

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''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 {

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 =

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

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
