Doesn't work erb engine

karen_k · July 3, 2010, 12:13pm

I’m new in RoR:)

I have controller and view (/app/controllers/greeting_controller.rb
and /app/views/greeting/index.rhtml /.erb/.html.erb - doesn’t match).

greeting_controller.rb source:

class GreetingController < ApplicationController
def index
@message = “Hello world!”
end
end

index.rhtml source:

test

<%= @message %>

and html output is exact copy of index.rhtml

i’m working on macOS 10.6.4

please help!!))

Quoting Karen K. [email protected]:

I’m new in RoR:)

I have controller and view (/app/controllers/greeting_controller.rb
and /app/views/greeting/index.rhtml /.erb/.html.erb - doesn’t match).

You don’t say which version of Rails you are using, so I will assume
2.x. If
1.x or 3.x, ignore this reply.

greeting_controller.rb and index.rhtml look fine. But they are not
following
Rails naming conventions, controller names are plural, i.e.,
greetings_controller.rb and /app/views/greetings/. index.rhtml is old
style
naming, preferred current practice is index.html.erb. These two changes
may
be enough to solve your problem.

I don’t understand the last bit of the sentence above. Please expand
what you
mean by “/.erb/.html.erb - doesn’t match”. Do you mean that
/app/view/greeting/index.erb and /app/view/greeting/index.html.erb are
ignored
by the template engine?

HTH,
Jeffrey

Yes!

It doesn’t make sense.

I’m using 2.x version.

Now controller name is Greetings, and view file name is index.html.erb

But the problem hasn’t been solved

Please tell us the current filenames and contents again to make sure
of what you have done. Have you removed all the old files? Rails has
a habit of loading files that you have left lying around by accident.
What exactly is the symptom now seen?

rename /app/views/greeting/index.rhtml to …/index.html.erb

Why it’s so hard?!
No bug report… Nothing…

Could you avoid top posting please, it makes it more difficult to
follow the thread.

What do you see in development.log?

Which version of rails are you using? You said 2.x but that covers a
lot of versions.

I am out of ideas as to why the erb code is not being interpreted.
Anyone else?

Random guess: a stray invisible character somewhere in the file.

may be something wrong with macos 10.6.4 and current version of RoR?

What do you mean by “current”? 2.3.8, 3.0beta – which is it?

Do you have a small test case you can post somewhere?

FWIW, I’m running 2.3.8 at the moment on Mac OS 10.6.4 with no
problems. Other than self-inflicted ones, of course

What? Do you mean rails 1.3.7? That is absolutely ancient, if it
ever existed at all. Do you mean 2.3.7? Type
rails -v
in your rails application directory to see what it is.

That seems unlikely - there never was a version 1.3.x of rails
(perhaps you’ve reported the version number of rubygems itself?)
