Hi ActionView::Helpers::FormHelper methods (e.g. #text_field, #check_box...) take object_name as an argument. From this argument they infer a name that is supposed to contains the reference to the relevant object. I can''t see why the FormHelper methods were designed that way. Compared to simply passing them a reference, the current way seems too complicated and an invitation to problems

Hello, Most of the form helpers are build using Object / Method without the possibility of using a method parameter (as I know ...) text_field(object_name, method, options = {}) how do you solve this problem ? -> (I did my own helper and generate the html ... well I think there is a better way;-) -> do I have to overide text_field(object_name, method, parameters {}, options = {})

Hi all My site has news entries, it has a party calendar and it has a blog. Now I''d like to create a commenting system that in fact is quite simple, but I wanna use it for all these 3 types of content. My question: how can I do that?

Community, I have been putting off implementing a Date selector for too long. Tonight, I finally put it in. I made the choice to go with the datebox engine. Once I got it installed and working, I realized I didn''t like the way it required you to call it. Example: <% @dateField = model.date %> <%= date_box %> or... <% @dateField1 = model.date %> <%=

Hi, is there a way to keep the already entered form fields when the form is re-displayed after some error has been detected and reported to the user via flash? Regards IJD -- Posted via http://www.ruby-forum.com/.

I have AMOUNT field that ActiveRecord maps to Float. Then I use text_field helper to generate text inputs on forms. Helper takes model object and attribute name and does not provide any formatting abilities, thus 2.40 is shown as 2.4 which is fine with floats but does not look good with currency. I have worked around this issue by adding amount_f attribute to the model that returns formatted

I''m using the fields_for helper with accepts_nested_attributes_for The System model has_many children.

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
