Hi:
This one''s a little wierd. I have a simple form using form_for,
it''s a
form for entering tasks. A few fields, no biggie. My submit button is
at the bottom of the page. I need to introduce the concept of sub-task.
The user can have one sub-task, or many sub-tasks. What I would really
like is a link or button that inserts a partial with another small form
for entering these subtasks. The number of subtasks that the user can
enter is variable and theoretically infinite.
Here''s the view:
<% form_for(:task, :url => tasks_path) do |f| %>
<table width="100%" cellpadding=0 border=0>
<tr class="spacerH10" >
<td colspan=3></td>
</tr>
<tr>
<td width="25%" >
<b>Task Name *</b>
</td>
<td width="37.5%">
<%= f.text_field :title %>
</td>
<td width="37.5%">
</td>
</tr>
<tr>
<td width="22.5%">
<b>Task 1:<b><br />
<b>Task 2:<b><br />
<b>Task 3:<b><br />
<div id="label_count"></div>
</td>
<td width="40%" valign=top>
<%= text_field_tag(''step_1'', ''enter Task 1
here'', {}) %><br />
<%= text_field_tag(''step_1'', ''enter Task 2
here'', {}) %><br />
<%= text_field_tag(''step_1'', ''enter Task 3
here'', {}) %><br />
<div id="new_task"></div>
<%= form_remote_tag :url => { :action => ''add_new'' },
:html => { :id =>
''addnew'' } %>
<%= link_to ''Add More Tasks'', :method =>
''add_new'' %>
<%= end_form_tag %>
</td>
<td width="37.5%" valign=top>
</td>
</tr>
<tr>
<td width="22.5%">
</td>
<td width="40%">
<p>
<%= submit_tag "Create" %>
</p>
</td>
<td width="40%">
</td>
</tr>
</table>
</table>
<% end %>
The controller code is complicated, but right now the "create" action
does what you would expect - simple insert.
I created a new method in the controller "add_new" but didn''t
put
anything in it. I would imagine it needs code to add maybe the previous
sub-task.
Finally, i created a partial for the new tasks:
<%= text_field_tag(''step'', ''enter Task
here'', {}) %>
and the RJS, again pretty standard:
page.insert_html :bottom, ''addnew'', :partial =>
''add_new''
page.visual_effect :highlight, ''addnew''
So, that''s it. When I click "add new task" the page
refreshes but my
DIV isn''t populated and basically nothing happens.
Any help you can provide would be greatly appreciated.
Mike

The W3C HTML spec says so. I had the same issue. It is possible, quite easy actually, to render multiple forms on one page. I render one each for the new tasks, then one (empty) one that looks to the visitor like the normal submit button but doesn''t submit anything - just moves them to another page. Note that this solution will not degrade gracefully if the visitor has js disabled. I decided not to even allow the visitor to visit that portion of my site if they don''t have js enabled. The alternative is to redirect them a ''crippled'' version of the page. You''ll need to think through what your site needs to do.

Here''s what I don''t understand: how would you actually submit the form on the top with a fake submit button on the bottom that didn''t do anything? Don''t tell me rails does that automatically? In the intervening period since I posted this question, I actually started using "link_to_remote" which actually looks much better for my form, becuase i need to inject lots of HTML depending on user controls and links. So here''s where I''ve landed (from the view, cut down for the relevant parts): <div id="new_task"></div> <%= link_to_remote "Add another task", :update => ''new_task'', :url => { :action => ''add_new'', :id => ''1''} %> My RJS hasn''t changed (add_new.rjs): page.insert_html :bottom, ''new_task'', :partial => ''add_new'' page.visual_effect :highlight, ''new_task'' and the partial is just some simple text as, per your suggestion, I''m building slowly (_add_new.rhtml): <b>insert complete</b> Again, the method "new_task" doesn''t have any code it it yet, but it will be probably to insert the previous task, I would think. Again, thanks for your continuing help. At this time, we don''t have plans for no javascript degredation. Thanks as usual, Bill.

Hi Mike,> Thanks as usual for your help.You''re welcome.> Here''s what I don''t understand: how would you > actually submit the form on the top with a fake > submit button on the bottom that didn''t do anything?You don''t. I use ajax (form_remote_tag, in my case) to submit each of items the visitor enters as they enter it.> At this time, we don''t have > plans for no javascript degredation.Then you probably want to take a real hard look at your approach. In the documentation, any method that mentions XMLHttpRequest requires js to be enabled on the browser if you intend to update anything in the page you''re showing the visitor. hth, Bill --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Bill:
Ok, I understand what you mean now. But here''s my next problem. When
I
do the HTML injection, I get javascript jibberish instead of the partial
as it should be. the partial is enclosed. Here''s what''s
showing up in
the div on the page after I click the link:
try { new Insertion.Bottom("new_task", "insert complete");
new
Effect.Highlight("new_task",{}); } catch (e) { alert(''RJS
error:\n\n'' +
e.toString()); alert(''new Insertion.Bottom(\"new_task\",
\"insert
complete\");\nnew Effect.Highlight(\"new_task\",{});'');
throw e }
So my HTML is in there somewhere. What am I doing wrong?
Thanks again,
Mike

Hi Michael, Michael Schuerig wrote:> That won''t work if there are validations that > require the presence of multiple attributes, or > does it?Lots of ways to handle it. Object.save_with_validation(false) will let you handle it in the database once everything you need to validate has been entered. You have to track what''s been entered, of course, and then either save with or without validation depending on what you want to do. hth, Bill --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Bill Walton wrote:> Sorry. You''ve lost me. Start over.You think you''re lost! :) Ok, so, with your help I was able to get the following link_to in my viewer code to work: <%= link_to_remote "Add another task", :update => ''new_task'', :url => { :action => ''add_new'', :id => ''1''} %> the div I want to update into is right above this part of the view, so: <div id="new_task"></div> <%= link_to_remote "Add another task", :update => ''new_task'', :url => { :action => ''add_new'', :id => ''1''} %> But! When I click my link, instead of the contents of my partial, as specified in my RJS, I get the Javascript jibberish inserted into my div, instead of just the HTML. The jibberish is in my previous post. My RJS hasn''t changed, looks like: page.insert_html :bottom, ''new_task'', :partial => ''add_new'' page.visual_effect :highlight, ''new_task'' I know that this is at least somewhat working, becuase when I click the remote link (add another task) the div is filled with the jibbersh, and it also highlights, per the RJS. That''s where I am, is that more clear or is there something else I''m omitting? Thanks again for all of your help!

If you are using RJS then you are telling the page what to update already so this is messing things up.

Matt: Yep! That did it! Thank you so much! As being able to see the onion was never enough for me, and I always need to be able to peel the onion, would this same thing be possible without the RJS?
