Basic select drop down returning the right params

Rails
1

Anyone mind helping with he following, whatever I do I can’t get it to
work quite right, I want the selection dropdown to show a list of
enquiries maybe by Enquiry.firstname and when selected the show action
to display the enquiry, I know this should be mega easy but I can’t get
it to work with colleciton select.

controller index action

def index
@enquiries = Enquiry.find(:all, :order => ‘created_at ASC’)
end

view

<% form_tag :controller => ‘enquiries’, :action => ‘show’, :id =>
@enquiry do %>

SELECT HELPER ? COLLECTION SELECT?

<%= submit_tag “Show” %>

controller view action

def show

@enquiry = Enquiry.find(params[:id])

end

anyone? I just need a basic dropdown which passes the id of the selected
enquiry.

controller view action

def show

@enquiry = Enquiry.find(params[:enquiry][:id]

end

Try that.

Hope it helps. NOTE: I didn’t test it, but I’m pretty sure it’s right,
which means you may have to tweak it. :wink:

Also of note, if you want something different to show up in the select,
you can add a method to your model that returns the proper text and
substitute that for :firstname in your collection select.

i.e.
class Enquiry
def last_comma_first
self.lastname.to_s + ', ’ + self.firstname.to_s
end
end

<%= collection_select :enquiry, :id, @enquiries, :id, :last_comma_first
%>

any ideas, does my show action need to change, or the collection select,
OR the params passed from when I move to the show action from the edit ?

bump…

Darrick,

That’s great thanks, I tried this before (or something very similar and
it worked)…Here’s the problem though…

That show action works your way from the collection select drop down…

However…
When I do it this it brakes something else (the show action after I’ve
editted a form).

e.g this URL.

http://localhost:3000/enquiries/show/5

I see why it’s broken I just don’t know how to fix it…so it’s like
I’ve got two situations, one from the dropdown and one from a regular
form and I’d like the show action to deal with both?

Hope that makes sense… BTW I love the enhancement in my model which I
did giving first initial then lastname…

Any ideas?

What makes you think your question is more important than everyone
else’s?

If you’re using RESTful routes, that url should be:
http://localhost:3000/enquiries/5/show

Not sure how you’re getting to the other. Are you using the url
generator methods? e.g. enquiry_url(@enquiry) and friends?

If you use the url generator methods for all of your links, you
shouldn’t have any problems. Use these as parameters to redirect_to and
link_to.

<%= link_to ‘list’, enquiries_path %>
… or …
redirect_to enquiry_url(@enquiry)

How are you generating the url you listed above?

Darrik
