I''m stuck in trying to get an embedded expression in ERB.
I''m trying to put @post into @httppost. However when I print @httppost
I
get (notice the @post):
{"aps": {"badge": 1, "alert", #{@post}},
"sound": "cat.caf",
"device_tokens":
["455ab1b23cbfd97b7d2ef90a49d222e40f4c6c9b2570e84ff94fe4afeea12345"]}
It should say:
{"aps": {"badge": 1, "alert", "This is a
test"}, "sound": "cat.caf",
"device_tokens":
["455ab1b23cbfd97b7d2ef90a49d222e40f4c6c9b2570e84ff94fe4afeea12345"]}
I put everything in my view to make it easier to troubleshoot:
<% @post = params[:post] %>
post params: <%= @post %>
<br />
<% @httppost = ''{"aps": {"badge": 1,
"alert", "#{@post}"}, "sound":
"cat.caf", "device_tokens":
["455ab1b23cbfd97b7d2ef90a49d222e40f4c6c9b2570e84ff94fe4afeea12345"]}''
%>
<%= @httppost %>
You can see the enclosed screen capture to see what my results are.
Thanks in advance.

The ''!'' can be whatever you want (I think) so pick something that isn''t in your string.
