checkboxes with a has_many :through relation
All,
I''m populating a view with checkboxes in a list. I want to be able to
assign to my has_many relationship using the post values of these
checkboxes. Essentially, I want to populate the relationship table
which will create the correct join values in my model.
Here is my check_box_tag code:
<%= check_box_tag("@current_job[target_list_ids][]",

What does the send() method do on a model object?
All,
I did a scaffold for a model and I ended up with this code in
list.rhtml:
<% for column in TargetList.content_columns %>
<td><%=h target_list.send(column.name) %></td>
<% end %>
Where is the "send" method and what does it do?
I can''t find it on ActiveRecord::Base? I assume that it returns a
value based on the column id but I

Wrap error_messages_for() call when no instance var present
I am trying to put some smarts around a call to
<%= error_messages_for %>
so that when I first come into this page i.e. when my instance variable
@target_list has not been defined yet, the page doesn''t break.
I''m doing this:
<% if @target_list? %>
<%= error_messages_for ''target_list'' %>
<% end %>
I get a syntax error on line 1.

has_many :through and foreign key parameters
I just took my HABTM and turned it into a :through since my join table
has another "non-joiny" attribute.
I went from this:
has_many_and_belongs_to :jobs, :join_table => ''tablename'',
:foreign_key => ''x'',
:association_foreign_key => ''y''

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:

rake migrate VERSION=0 doesn''t appear to execute
All,
I''ve decided to jump into Migrations before I get too far along on the
DB side of things.
I already have some tables built, and I went ahead and built the
migration that would have created them from scratch, and I made sure
that there was a self.down section to drop them. I wanted to verify
that I could roll back so I figured I would use rake to drop these
pre-existing tables

Best practices - field initialization based on display rules
All,
I have a form with the following field interaction rules.
Given checkbox A,
text field B
text field C
If checkbox A is checked then make text field C equal to the value of
text field B and disable field C.
If checkbox A is unchecked then enable field C.
In order to display a form where I''m manipulating an already existing
object, I have something like this in my RHTML template

ERb question: Embedding <%= %> in helper method calls
I had a situation where I wanted to use a <%= %> (scriptlet) in my
text_field call to set the "disabled" attribute on the text field, like
so:

''offset'', :maxlength => 2, :disabled => <%= sometest ? ''true'' :

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

Form validation - keepin correct fields displayed on refresh
All,
I''m finally doing my first real form in Rails - the model object that
I''m entering information for has 8 validations so far.
If I type in good values for all the fields but one, I get the pretty
validation, and the nice field highlighting, but all of the fields are
cleared, forcing me to retype all of that info. That is a big drag.
Is there a standard way to get the

Setting a global before_filter action in application.rb
Can you set a global before_filter action in application.rb?
So, for example, you could control authentication for all of the
controllers in an app.?
Obviously, you would need a way to reference actions by controller
within this "global before-filter".
Thanks,

Best Practices: Splitting the "view model" from AR model
All,
I''m starting to see view state information creeping into my model class.
For example, I have text fields in my view that need to be set a certain
way depending on whether or not a checkbox is checked. And while the
values of these text fields ultimately do represent database columns
that are related to the backing AR object, the text_field values also
represent attributes on a

Best way to use partial rendering in global layout
I have a global layout in application.rhtml and I''d like to render a
partial template within it.
Currently, I have this:
<%= render (:partial => ''side_nav'') %>
but it seems to be looking in the controller specific view directory.
What is the best way to do handle controller - global partial rendering?

AJAX in conjunction with partials
All,
Trying to clear up some confusion on my part.
If I make an Ajax call using Ajax.Request and in the controller method
that I call, I do a render (:partial => ''whatever.rhtml''), should I
expect that ''whatever.rhtml'' will be rendered in the browser or not?
Put another way, is it in any way reasonable for me to think that

Newbie: Can''t get file to upload
Since I can''t get the fancy upload progress thing to work, I thought
that I would revert back to a regular file upload scenario.
I have a very simple file upload form set up. It appears that my file
parameter is coming into the controller as a string, not a file object.
Here''s my view:

Implementing HTTPS with WEBrick?
All,
I would like to test some secure pages that I''m developing in my
WEBrick-based development environment.
I''ve done some research and it appears that I need to create a new
command that will start a HTTPS based WEBrick server. Is this correct?
Also, it appears that the https.rb module is not included with the
WEBrick bundled in Rails. So, I will need to go get that

Setup new data in the test database _after_ unit test runs
All,
I want to run automated unit tests as part of my build. I am building
to my test environment. Upon successful completion of all of my unit
tests, I would then like to load some data (using a fixture, I imagine)
into my test database that will act as fresh "system test" data for my
users to play with.
What is the best way to "load the standard system test/user acceptance
