Server problems.really Weird

Rails
1

My question might be very basic, so please bear with it.

Q.1 suppose i created my rails app as APP1 under the directory /abc/
xyz and then I copy the entire directory to a different location, say /
cde/efg/. Now, if i go in the new location and call the rails server
command, will it work?
I guess it should, never had such an issue but today all of a sudden,
the server doesn’t even show a single home page.
P.S. I am not using RVM, and using Rails 3, so the ruby and gemset is
same over both the rails apps.

Q.2 What should one do when the server is showing cached copies of the
previous apps. for example lets say i have app1 : posts(the only model
made by scaffold), app2 : users (the only model made by scaffold) and
similarly one more app. Each one of it is separate, as you all know,
are independent.
Today , when i created a new application and i started the browser, it
kept on pulling up pages from the cache and didn’t show me the views
for the new app. A point to note that the server log is blank, nothing
gets executed as per the server.
P.S. These are not three controlles, rather three whole rails
apps…and my environment is Development, so no point of production
cache.
Help me fix these issues.

I posted the above question @stackoverflow.com
http://stackoverflow.com/questions/4368668/server-problems

Didn’t get an answer, why it was happening so? A day later, it all
went fine by itself.

So, I edited my question appending

" I don’t know how, but all the issues are fixed now, on their own.
Does any one has any idea what led to this? "

Now, I am having the problems again:

" Initially atleast It was showing me some cached html (or whatever)
of the previous apps from nowhere, but now, its not working at all…i
mean rendering nothing at all. Any idea, where the problems might
be??? "
Please help me, as I am stuck with this, I can’t proceed with my
project.

First, please let us know what you are using for a webserver – at least
I
dont seem to see that you named it – webrick, mongrel, nginx…

The server I am using is Mongrel and Webrick. When Rails was showing me
cached views out of nowhere, I tried both these servers( i mean, i
changed
the Gemfile in Rails 3.0 rc2 ) and again started the server(first time
with
mongrel, and second time with Webrick), the results were same.
And now that it is not even showing me those garbage cached views, i
have
tried both webrick and mongrel.
What I can see is there is some problem with the Rails gem, what do you
say?

I’d say, why are you using an old pre-release version when Rails is
already at release 3.0.3 ? :slight_smile:

Update and see if your problem persists.

It usually should.

Yes, it usually should but not working now, probably because there is
some
problem in my Rails gem.

I guess it should, never had such an issue but today all of a sudden,

the server doesn’t even show a single home page.

And the error message said…? And to fix it, you tried…?

The error message said NOTHING. The server log is empty, with nothing on
it.

for the new app. A point to note that the server log is blank, nothing
gets executed as per the server.
P.S. These are not three controlles, rather three whole rails
apps…and my environment is Development, so no point of production
cache.

We’ll need to know more about your setup to answer this.

What exactly do you need to know about my setup.?
linux ubuntu 10 lucid x86, ruby 1.8.7, rails 3.0 rc2
I feel like there is some problem with my rails gem. Do you suggest to
reinstall it and then see if the problem persists?

Have you checked that the browser is not set to work offline? In
Firefox that is File > Work Offline.

Oh god and a good point as far as caching. I don’t like this feature on
Firefox… actually on most apps I dont like them making that kind of
decision for me, reminds me of Windows. Does anyone know of a way to
disable
this on FF?

I suspect it is your browser showing the cached copies rather than the
server.

Today , when i created a new application and i started the browser, it
kept on pulling up pages from the cache and didn’t show me the views
for the new app. A point to note that the server log is blank, nothing

The fact that the log is empty suggests that either the server is not
working correctly at all or it is not receiving any requests. Again
are you sure it is not the browser that is showing from its cache?

P.S. These are not three controlles, rather three whole rails

" Initially atleast It was showing me some cached html (or whatever)
of the previous apps from nowhere, but now, its not working at all…i

When you say rendering nothing at all, what do you see in the browser
and what is in the log. What do you see if you view the page source
in the browser and what url are you entering in the browser? Timeout?
Blank page or what? (View > Page Source or similar in browser to show
the page html).

Post the output shown when you start the server.

Just don’t choose the Work Offline option.

I think the point is that sometimes if there is a connection problem
FF will switch itself into offline mode without any very obvious
indication of what is going on.

@OP, was it operating in offline mode? Have you still got a problem
or was that all there was to it?
