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?

Does text_field go directly to attributes hash in AR object?
All,
I''m having a hell of a time figuring out what is going on here.
I''m trying to override one of my getters so that I can format it a
certain way in my form. But I can''t seem to get text_field to call the
appropriate method on my object.
So here''s my getter:

Code reviews: my dumb use of acts_as_commentable (newbie)
With the help of several heroes here yesterday I beat my way into a
working solution to adding comments to one or more models in my
application using acts_as_comentable. Great plugin, but my
implementation is lame. I need enlightenment.
I have users who log in. For several views I want to let them add
comments. Enter act_as_commentable which does just this -- it''s

the value in text_field helper
I have been working on this small, minute, part on my project and it all
hinges on setting the value in a text_field helper. Saying:
<%= text_field ''user'', ''company'', :value => @login %>
does not do it. When I go and look at the raw html, there is no value
there and "value" is an attribute of the input tag, im pretty sure. I

text_field behaviour with validations
Hi,
The text_field method sets the class of the field to "invalid" when the object
you specified is invalid (when using validations). This is to facilitate
working with validations.
Is there anything else it does? In a certain non-standard situation I''m forced
to use text_field_tag, instead of text_field. This means I have to take care
of the validations myself as well.

Refreshing RHTML page with previously posted data?
All,
After a POST, I want to be able to redisplay a view with the data that
was previously entered when my controller action notices a validation
failure and calls render on the view that does the submit.
Example:
View x.rhtml - text field is filled in
Call controller action
Controller action fails validation calls render (:action => ''x'')
x.rthml shows up with blank text

Does collection_select work in list.rhtml?
Hi,
I have 2 models:
Model 1: er, Columns: <er_id, er_name>

A quick question on forms
I want to change parts of this form in order to use default values (with a
disabled input). The problem is if I change it from text_field to
text_field_tag that part of the form stops functioning. It seems like a
silly question, but its been driving me crazy. Any help would help.

Understanding Form_for
OK, so I''m an absolute noob at Ruby on Rails. I''ve read a lot of
information I can find about form_for and most of them use form_for to
create new items that get saved into the database and can be viewed
later to edit, destroy, etc. In this case, the database will fill up
with whatever the user wrote and I just want my program to have no
information stored.
