ActionView::Helpers::FormHelper instance methods should take an object reference rather than an object_name.
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

Changing scaffold''s text_field to a password_field causes white screen of death in mozilla?
I had posted earlier about ''silent failure of a controller'', what seemed to
be an intractable problem where I was getting failure of a particular action
in a controller while others worked. What was irritating was that there were
no useful messages. Nothing to the browser, nothing in logs, and even the
breakpoints wouldn''t hit. Finally by a process of elemination I found

Framework question about FormHelper ...
Hello,
I don''t understand how formhelper works (In a Framework point of view) ...
For example if I use the chek_box formhelper
1/ check_box("puppy", "gooddog", {}, "yes", "no") will call @puppy.gooddog
BUT, how it is possible since the check_box has only a string parameters
not instance object ?

Overriding ActionView::Helpers::InstanceTag::DEFAULT_TEXT_AREA_OPTIONS
What is the best way to override some of the FormHelper default
options? Right now I''m adding this to the beginning of my
environment.rb:
ActionView::Helpers::InstanceTag::DEFAULT_TEXT_AREA_OPTIONS = { "cols"
=> 80, "rows" => 5 }
Is that the way it''s supposed to be done?

Using view helpers from a controller
Hi,
I want to access a view helper from a controller.
(Of course, you all want to know why??? -- See below.)
To be specific, I want to access methods such as
ActionView::Helpers::FormTagHelper -- form_tag and text_field_tag
from either a controller or from a new class (in models? or lib?).
If I create the new class then that class''s methods need to also be able

formhelper password_field only takes two arguments
When I look at the docs, password_field seems to take 3 arguments.
So when I ''play around" with things and I attempt to pass three
arguments to password_field ... I get an error saying that it only takes
two parameters ("3 for 2")
I am totally lost.

Advice, why value_before_type_cast in FormHelper?
I am wondering why is in creating text fields with form_helper used
value_before_type_cast instead of attribute value for field value?
I set rails enviroment so date fields are in european format
(dd.mm.yyyy) and would like to have same format in forms, but because of
value_before_type_cast is called, form fields are filled with
''yyyy-mm-dd'' or timestamp integer, etc.

Custom view helpers
Hi all,
I would like to write some custom helpers like the ones available as
form helpers text_field, text_area and the like. My first try was this:
custom_helper(obj, meth)
''some_string'' + obj.send(meth) + ''some_other_string''
end
Object and method are being passed as symbols like this:
custom_helper(:person, :name)
and Ruby rightfully complains that

text_area_tag not escaping content by default
I stumbled on the fact that text_area_tag does not HTML escape its
content by default. For example:
text_area_tag "body", "</textarea><script>alert(''xss'');<script>"
If you try that, you''ll see that the content is inserted literally.
Considering the fact that the tag helpers all encode their attribute
values by default, does this

select or select_tag ?
hello PPL,
I''ve seen now that the _form.rhtml generated by script/scaffold is
populated by
<%= text_field ''model'', ''field'' %> without _tag!
but only text_field_tag is to be found in the 1.1.2 documentation..
(like in the rest of Module ActionView::Helpers::FormTagHelper there
is _tag)

FormTagHelper form names: possible?
Thank you to everybody that has helped me since I signed up. I''m flying

I have a question about the FormTagHelper "start_form_tag": I''ve been

How to extract the variance componets from lme
Here is a piece of code fitting a model to a (part) of a dataset, just
for
illustration. I can extract the random interaction and the residual
variance
in group meth==1 using VarCorr, but how do I get the other residual
variance?
Is there any way to get the other variances in numerical form directly -
it
seems a litte contraintuitive to use "as.numeric" when extracting

pass text_field to controller when using periodically_call_r
Hi. Can anyone help with this? In a view, I have a text_field_tag(
:mytextfield ). I would like to pass the current value of that
text_field_tag to a periodically_call_remote - something like
periodically_call_remote( :url => { :action => :do_it, :thetextval =>
:mytextfield.value } ) - Any idea how can I pass and/or access the value
of the text_field_tag in my do_it controller?
