similar to: How do you use form helpers in your controllers or classes?

Can someone explain why form helpers appear to bypass any model methods I override for fields that are bound to database fields? It would be great if someone could tell me how to force the form field, etc to call the method instead of looking at the database / attributes collection. Let''s say I have a column called ''price'' in my database table "books"

Hi, In our project, we have a number of forms to be filled by the users. The forms are presented as wizards - each form as a number of steps. I would like to know whether there is an existing helper developed by the Rails community that can let me create wizards easily. We also want all wizards to have the same look and feel.

I''m trying to use the select helper but do not need to pass the values back to an object because this is just used as a param value. Everywhere I''ve looked I see that the form field helpers require an object name. I''ve tried omitting the name but I get an error telling me I have two few paramaters. (2 out of 3) Other than typing out the HTML myself (because the

Hi there. In the process of learning Rails I''m displaying data from my model in an HTML table. The view template got really messy so I decided to build a class to tidy things up and help me with the table generation. I started out putting it in the controller. But then I thought that the right place for it (following the MVC pattern and Rails orthodoxy) would be in a view helper. But

Hi there, I''ve got a problem I''m hoping someone else has run into before and might have some tips on.

I have been using rails professionally for only a month and a half now, but I am continually running into problems with form helpers and accessing multiple objects on a single page. To whit: 1. While text_field and text_area and such all support the :index option, the select helper does not. 2. When appending the text ''[]'' to a helper''s object name, the id is

Here is what I''m working with in my app: user model - (the table where a user registers their information) it contains the following fields - first_name last_name email account_type (currently set to string but will probably be a select box with options) password_salt (I''m

Anyone have a quick solution on how to format a number in a text_field tag? <% text_field "price", "amount" %> returns 100.0 and it would be nice if it showed 100.00 Of course, number_with_precision works nicely, but how do you make that work with text_field? I thought maybe overriding the getter in the model. However, this means I would have to bring the helper

I have an ActiveRecord model (called Festival) that contains an array of "FestDate" objects serialized into a sql text column of the Festival object. (like the Agile book first edition describes on p. 205) The FestDate objects themselvs are not ActiveRecord objects. (of course, otherwise they would be in their own table...) When working with a Festival, I would like to use various

Hello, Today I noticed that the number_to_currency helper didn''t work anymore (it just returned the numeric value, without any currency).

Hi there, I''ve been trying to override the text_field helper with a version in my application helper.

Hi all, I''m in the process of creating rspecs for my helpers. One of the helpers in app/helpers/application_helper.rb looks like this: def page_name @page_name || "Define @page_name in #{controller.controller_name}::#{controller.action_name}" end The rspec is simply: it "should something" do page_name end
