Forms extension

Ruby Apps Radiant CMS
1

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.

try the aissac fork. i’ve setup mailer with attachments before and i
think that was the fork i used (if not poke around the network and
you’ll find it).

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’

  1. 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 containname’ and `view’
    attributes”)
    end
    end

  2. Call the tag from my Radiant template:

<r:cell name=“question_instances” view=“new” question_type_id=“9”/>
