Questionairee's questions - how to show all user's answers? How to update database with ALL user's

Rails
1

I am using RoR 2.3.5.
I would like to have list of questions with three possible answers.
After having copleted a test I would like to update the database with
user’s answers. At the bottom of the page I would also like to list
all selected answers for the user.

In a table “answers” I have columns: question, a1, a2, a3 (these
columns are answers to the question),
a_u (user’s answer), a_ok (correct answer). Below I have pasted the
view that I am using for listing questions.
But I have no idea how to list ALL answers at the bottom of the page
(now I know how to show only one answer). And how (in the most
effective way) to update the column “a_u” wtith ALL user’s answers?
Could you help me?

#-----------------------------------------------------index.htm.erb
begin------------------------------------------------------------------

Listing answers

<% @answers.each do |answer| %>

<%=h answer.question %>
<input type=“radio” name=“answer1” value= <%=answer.a1%> /> <%=h
answer.a1 %>
<input type=“radio” name=“answer1” value= <%=answer.a2%> /> <%=h
answer.a2 %>
<input type=“radio” name=“answer1” value= <%=answer.a3%> /> <%=h
answer.a3 %>

<% end %>

You selected <%= @data11 %>
#-----------------------------------------------------index.htm.erb
end------------------------------------------------------------------

In answers_controller I have included:

@data11 = params[:answer1]

Surely you have a “Question” model, which has the question text, and
the three choices for answers (or even a “Choice” model, with a
“Question :has_may Choices” relationship…), and in the “Answer”
model you just store the question_id and the choice (or choice_id).

For every question the user completes you have an Answer record
(created when they answer a question, or updated if they’re allowed to
edit), so users have many answers, and you can iterate to display all
wherever you wish.

Hi,

Could you let me know what shuld be included in controller to list on
the page ALL user’s answers? I also think that the view should be
modified to show ALL user’s answers - but I have no idea how it should
be changed. Could you modify it?

You could populate a variable with the results of a find of the user’s
answers, or just have a variable for the user and access
“@user.questions” in the view.

I also think that the view should be
modified to show ALL user’s answers - but I have no idea how it should
be changed. Could you modify it?

Are you asking me to do your work for you for free?!

Do you suggest that I shuld pay you for the answer? :). I am learnig
RoR and I don’t know how to solve the problem - it is not my work BTW.

If I were you I would buy a book or find info on the web and study how
activerecord associations work. That will most likely clear all your
questions and help you solve the problem. The examples I’ve read in
any of the books I have are very clear. Good books: Agile Web
Development with Rails and The Rails Way.

Good luck.
