Hello all,
I am still very new to programming and wonder if I could get some help.
I have tried to figure this out myself but still having trouble with
some of the concepts. I’ll do my best to explain the problem and
include the code. I may be completely off track, so ANY direction
offered would be deeply appreciated.
I have a question model / object which consists of a question, answers,
and responses to the answers. In the model have the following method
to shuffle the answer –annotation(response) pairs so they don’t look the
same every time they are viewed.
Question.rb model
def set_format_for_presentation
# Create array and shuffle incorrects.
answer_list = [
[incorrect_ans_1, incorrect_anno_1],
[incorrect_ans_2, incorrect_anno_2],
[incorrect_ans_3, incorrect_anno_3],
[incorrect_ans_4, incorrect_anno_4],
[incorrect_ans_5, incorrect_anno_5],
[incorrect_ans_6, incorrect_anno_6]
].shuffle
# Randomly insert the correct answer and response into the
shuffled array.
random_insert = rand(4)
answer_list.insert(random_insert,["#{correct_ans_1} *",
self.correct_anno, self.question_pict])
formatted = {
:anno_1 => answer_list[0][1],
:anno_2 => answer_list[1][1],
:anno_3 => answer_list[2][1],
:anno_4 => answer_list[3][1],
:anno_5 => answer_list[4][1],
:question => self.question,
:answer_a => answer_list[0][0],
:answer_b => answer_list[1][0],
:answer_c => answer_list[2][0],
:answer_d => answer_list[3][0],
:answer_e => answer_list[4][0]
}
formatted
end
In the controller:
@question = Question.find(params[:id])
@formatted_question = @question.set_format_for_presentation
In the view:
<% form_for(@formatted_question, :url => "controller =>
question",
:action => "show") do |f| %>
<div id="questionpict">
<p>
<%= image_tag @question.question_pict, :alt => "eye.jpg",
:size =>
"470x470", :style=> "border: 3px inset #d7b9c9;" %>
</p>
</div>
<div id="show_formatted_question">
<p>
<br /><%= @formatted_question[:question] %>
</p>
<p>
<br /><%= "A. #{@formatted_question[:answer_a]}" %>
</p>
<p>
<br /><%= "B. #{@formatted_question[:answer_b]}" %>
</p>
<p>
<br /><%= "C. #{@formatted_question[:answer_c]}" %>
</p>
<p>
<br /><%= "D. #{@formatted_question[:answer_d]}" %>
</p>
<p>
<br /><%= "E. #{@formatted_question[:answer_e]}" %>
</p>
</div>
<div id="ajax_area">
<p>
<%= render :partial => @anno %>
</p>
</div>
<div id = "buttons">
<%= link_to_remote(
"A",
:url =>"/questions/#{@formatted_question[:id]}/_anno_1",
:method => "get",
:update => "ajax_area") %>
<%= link_to_remote(
"B",
:url =>"/questions/#{@ formatted.id}/_anno_2",
:method => "get",
:update => "ajax_area") %>
<%= link_to_remote(
"C",
:url =>"/questions/#{@ formatted.id}/_anno_3",
:method => "get",
:update => "ajax_area") %>
<%= link_to_remote(
"D",
:url =>"/questions/#{@ formatted.id}/_anno_4",
:method => "get",
:update => "ajax_area") %>
<%= link_to_remote(
"E",
:url =>"/questions/#{@ formatted.id}/_anno_5",
:method => "get",
:update => "ajax_area") %>
</div>
<% end %>
Partial partial_anno_1.html.erb
<p>
<br /><%= "#{@formatted_question[:anno_1]}" %>
</p>
My goal is to use ajax to display the partial associated with the button
clicked eg click the “A” button and display “_anno_1”. Cant figure out
how to get the information in the variables to the partial. I cant use
set_format_for_presentation again as it will reshuffle tha attributes
and responses will no longer match the order the displayed answers are
in.
Thanks,
Dave Castellano

In order to display the partial associated with the button clicked, use CSS and Javascript. - Add CSS display attribute (something like *#activeContent{display: block;}*). - Add an *onclick* action to each button that "*activates*" a partial associated with the button so clicked and "*deactivate*" the other buttons - To deactivate the other partials, set *#activeContent*''s *style.display = ''none'';*.

Keep them in arrays, with some constant defining the size. Then you can just iterate over the array or range. If you need to change the size of the array, you can then be guaranteed that you haven''t forgotten to add or remove an entry somewhere.> <%= link_to_remote( > "B", > :url =>"/questions/#{@ formatted.id}/_anno_2",And now a possible forehead-slap moment. Might the space after the @ sign (which you have on some but not quite all of the other lines) be causing at least part of your problem? Iterating will also reduce the number of places where you have the opportunity to make such mistakes. A wise man once said, the best code is no code at all.

Edmond, Thanks for the response. It helped set me in the right
direction!
I put this in the show.html.erb:
<a href="#"
onclick="Element.toggle(''response_a'')">A</a>
<a href="#"
onclick="Element.toggle(''response_b'')">B</a>
<a href="#"
onclick="Element.toggle(''response_c'')">C</a>
and this in the .css:
#response_a {display: none}
#response_b {display: none}
#response_c {display: none}
Only problem is it only toggles if I change ''display: none'' to
''display:
""''. And then it doesn''t hide the responses when
the page initially
renders, which I need it to do. Any ideas??
Thanks again,
Dave

did...

</div>
<div id="response_b">
