I used apotonick's cells so that I could embed a regular Rails form
(rendered through Rails) in a Radiant page. I found the Radiant
extension too limiting.
This is rather involved though. What I like about it is I can embed
arbitrarily complex forms without having to leave the Radiant rendering
system. I plan to write this up at some point and put it in the Wiki.
At a very high - level, here's how I did that.
1) Install cells 3.3.4 (anything higher is Rails 3 specific)
2) Added these commands so that cells can be processed from within
Radiant (I did these in a custom extension (and the pathing reflects
that), but you could theoretically do them anywhere in the
initialization process, as long as you got the paths right):
CELL_PATH = "#{File.expand_path(File.dirname(__FILE__))}/app/cells"
CELL_FILES = Dir.glob("#{CELL_PATH}/*_cell.rb").map {|f|
File.basename(f)}
##Cell configuration
#Modify view paths for ::Cell::Base to include local cell view
directories
::Cell::Base.view_paths += [CELL_PATH, "#{CELL_PATH}/layouts"]
#Add CELL_PATH to Rails $LOAD_PATH
$LOAD_PATH.unshift CELL_PATH
#Require each Cell class
CELL_FILES.each {|f| require f}
3) Created cells to render my form. Here's an example:
app/cells/question_instances_cell.rb:
class QuestionInstancesCell < ::Cell::Base
def new
@question_type = QuestionType.find(@opts['question_type_id'])
if @question_type.question_type =~ /FAQ/
@question_instance = QuestionInstance.new()
view = :edit_faq
else
@question_instance = QuestionInstance.new(:question =>
@question_type.questions.first)
view = :edit
end
render :view => view
end
end
/app/cells/question_instances:
-rw-r--r--@ 1 weyus staff 568 Aug 30 16:46 edit.html.haml
-rw-r--r--@ 1 weyus staff 658 Sep 6 13:21 edit_faq.html.haml
/app/cells/question_instances/edit.html.haml:
- type = @question_type.question_type
- form_for [:admin, @question_instance] do |f|
= f.error_messages
%p
= type
%br/
= f.select :question_id, @question_type.questions.map {|q|
[q.question, q.id]}
%p
= f.label :question_text, "Edit the question to best fit your
selling situation"
%br/
= f.text_area :question_text, :value =>
@question_type.questions.first.question, :class => 'short'
%p
= f.label :new_form, "Would you like to build another #{type}
question?"
= check_box_tag :new_form, 1, false
%p
= submit_tag 'Submit'
4) Created a custom tag to allow for a cell to be rendered inside of a
Radiant template:
tag "cell" do |tag|
if tag.attr['name'] && tag.attr['view']
name, view = tag.attr.delete('name'), tag.attr.delete('view')
tag.locals.page.response.template.controller.render_cell(name,
view, tag.attr)
else
raise TagError.new("`cell' tag must contain `name' and `view'
attributes")
end
end
5) Call the tag from my Radiant template:
<r:cell name="question_instances" view="new" question_type_id="9"/>

Has anyone used a forms/mailer extension for Radiant that allows a
file to be attached and sent with the form? I have a form working --
users fills in text, selects choices from dropdown, checks radio
buttons -- everything works, contents emailed successfully. I'm trying
to add the capability for people to select a file (photo) from their
computer to be attached to the email but I can't get it to work. If
you've got it working, could you please share your solution?
Many thanks.
