Noobie question here. :) I have a form with check boxes on them. I simply want the user to check the appropriate boxes, click the action (Add Visits). It''s my understanding, that these check box values go into a hash (add_visit_for_this_Pt), but I can''t seem to get this hash back to my controller for processing. Below is my form. Basically, all the controller is

I am not able to create a check box or a button that can check and uncheckall the check boxes that i have created. It can be a check box or button that checks and unchecks all the check boxes. <form name="czar" action=''<%= url_for(:action => "list_supplier") %>'' method=''POST''> <% i = 0 %> <% @hotels.each do |hotel|

Hi Group, I have a registration.html.erb page with the following JavaScript at the top which I use to validate form fields: <script type="text/javascript"> <!-- function validate(){ if ((document.myForm.email_projectname.value=="")|| (document.myForm.email_projecttype_id.selectedIndex<1)|| (document.myForm.email_region_id.selectedIndex<1)) { alert

Over a decade ago there was a problem with model.frame when the variable names were long: https://stat.ethz.ch/pipermail/r-help/2002-August/024492.html I have similar symptoms with R 2.15.3 on Windows 7: Browse[2]> x <- model.matrix(formula(myform), p$data) Error in model.frame.default(object, data, xlev = xlev) (from mice.R#601) : object is not a matrix My attempt at a work-around

Hi again, When you have an ''obeserver'' setup as follows: $(''myForm'').observe(''submit'', validateForm); If a user submits the form the ''validateForm'' function is called and is automagically passed the ''event'' to work with. This is fantastic! But is there a way to pass another argument to the function?

Hi, I would like to write a function which has the following syntax: myfn <- function(formula, ftime, fstatus, data) { # step 1: obtain terms in `formula' from dataframe `data' # step 2: obtain ftime from `data' # step 3: obtain fstatus from `data' # step 4: do model estimation # step 5: return results } The user would call this function as: myfn(formula=myform,

Hello! I have this page where I list all users in a table. There is checkbox in every row. My User-model has a "checked"-attribute. I have implemented the checkboxes like this: <%= check_box("user[]", "checked") %> Which outputs this: <input id="user_12_checked" name="user[12][checked]" type="checkbox" value="1"

A user sent me an example where coxph fails, and the root of the failure is a case where names(mf) is not equal to the term.labels attribute of the formula -- the latter has an extraneous newline. Here is an example that does not use the survival library. # first create a data set with many long names n <- 30? # number of rows for the dummy data set vname <- vector("character",

Hi all, The "form_for" helper and its friends "text_field_for" etc generate form fields with names like "forum[title]", i.e. using square brackets to denote attributes on model objects. Now, for the convenience of the user I want to do some simple client-side validation to check that some fields have been filled in. So I am trying to write javascript like "if

Hello, I''m trying to use the afterFinish parameter on the BlindDown effect, but it''s not working as I expect it to. My function appears to be called just as the effect is starting, not when the BlindDown is complete (finished drawing). Here''s the code that I''m using for the most part... Effect.BlindDown( mydiv, { afterFinish:Form.enable(myform) } ) Any

Hi all, I have a a really, really dumb Newb question... I am trying to use observe_form to use AJAX calls in order to refresh a particular page fragment using the form data. I have run into a stumbling block very early on in the process - how can I provide an ''id'' attribute to the form_remote_tag or start_form_tag methods? Specifying something like :id =>

I have an index.rhtml is rendered when the (main)controller is loaded. The page contains some check boxes and a submit button. See form code below. When I click the submit button, I get a 404. I don''t know how to post this data back to my controller where method "addvisit" is waiting. It works in WEBrick no problem, but doesn''t work in fcgi on DreamHost. I am

I am trying to deploy my first app on Dreamhost using Ruby on Rails. I followed the wiki, but I think I am missing something. I think it may be in my RoR code, but I am not sure. My app runs fine when run as http://localhost:3000/AddPatientVisit/addvisits AddPatientVisit is the controller and addvisits is the form that posts back to the controller. I got rid of the index.html in public

Event listener for a form being submitted is not catching an A tag with a submit in it. Example JS: $(form).observe(''submit'', function(e) { e.stop(); // Something }); Example HTML: <a href="#" onClick="myForm.submit();">Submit form</a> Any idea how to fix this without added more js to button?

I can''t figure out how to take that value that the user has chosen in the slider and put that into a form value. Does anybody know how to do this? Here is my code so far (It''s pretty much directly from script.aculo.us): <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"> <html> <head> <title>Text effects tests</title> <script

Hi All, I have a problem with actionmailer corrupting my html emails. It is adding the character ''3D'' before any quotes (single or double) in my source and smattering ''='' characters throughout as well. Very strange. Here''s an example from one of the emails: ________________ <body> <div id=3D''wrapper''> <div

Hi, I was wondering if it is possible to output validation errors in a nested form? I suppose this should be possible, but I am experiencing an error message that I can''t track down. The error I get is the following : TypeError in Store/orders#create Showing app/views/store/orders/new.html.erb where line #45 raised: can''t convert Array into String This is ocurring in the

Prototype 1.6.0.2 Internet Explorer 7 I''ve found that when I call $(''myform'').focusFirstElement(); to set focus on the first field in my form, that this statement "wrecks" the extensions I''ve added using Element.addMethods() if it executes before Element.addMethods(). When I try to call one of my exenstions, the IE7 JavaScript interpreter throws an

Hi, I had a function that looked like: diff <- lm(x ~ y + z) How can I pass the argument to the 'lm' function on the fly? E.g., if I pass it in as a string (e.g. "x ~ y + z"), then the lm function treats it as a string and not a proper argument. many thanks [[alternative HTML version deleted]]
