Radio_button in loop problem

Hi all, I can’t figure out why my radio_buttons won’t reflect the values
stored in my database. I read through some of the previous posts – is
it true that they don’t work with integers?

This is the code I’m using:

<% for question in @survey.questions %>
<%= debug question %>

<%= radio_button ( “question”, :question_id, question.option_one.id)
%>
<%= question.option_one %>

<%= radio_button ( “question”, :question_id, question.option_two.id)
%>
<%= question.option_two %>
<% end %>

The “debug question” statement prints out the correct values. I have to
think that I’m using the wrong parameters in the radio_button call, but
nothing I try is working.

I guess I could use the radio_button_tag builder but radio_button seems
better. Any help would be greatly appreciated!

Thanks,
Eugene

This vaguely rings a bell with me Eugene. It would be helpful if you
could
post the html that this produces. Meantime…

Did you try putting “question_id” rather than :question_id ?

Did you try putting question.option_one.id.to_s ? The helper is maybe
looking for a string, and you are giving it an integer.

Hopefully my lame attempt to help might inspire someone who knows what
they
are talking about to give you a definitive solution :slight_smile:

Hey Robert, thanks for the reply!

Here’s the code I’m using (I remade my project, so some of the names
have changed)

– view code –
<% for choice in @survey.responses %>
<%= debug choice %>
<%= radio_button ( “choice”, “answer_id”,
choice.question.answer_one.id.to_s) %>
<%= choice.question.answer_one.text %>
<%= radio_button ( “choice”, “answer_id”,
choice.question.answer_two.id.to_s) %>
<%= choice.question.answer_two.text %>
<% end %>

– html produced –

--- !ruby/object:Response
attributes:
  question_id: "1"
  survey_id: "1"
  id: "1"
  answer_id: "2"

green
blue

So, debugging the choice var shows that answer_id=2, but the radio input
isn’t selected.

Did you try putting “question_id” rather than :question_id ?

I did try this, and it didn’t change my results.

Did you try putting question.option_one.id.to_s ? The helper is maybe
looking for a string, and you are giving it an integer.

This doesn’t work either, unfortunately.

they

I appreciate your reply, do you (or anyone else) have any other ideas?

Thanks,

To all who follow in my footsteps, I’ve decided to go with the
radio_button_tag
(http://api.rubyonrails.org/classes/ActionView/Helpers/FormTagHelper.html#M000501)
which was infinitely easier for me to configure. Good luck, and if
anyone does get this working with the radio_button helper, I’d be
interested to know how.

Hmm, I’m starting to think it has something to do with having to use an
instance variable … sound right to you? I’m experimenting right now,
I’ll post any progress.
