Hi,
I have a model user.rb, a controller userdata_controller, methods
in the controller and respective .rhtml files. I created a
registration page. Saved into users table and it works fine. But
sometimes its throwing error as
It assumes that there is no field 'city' in table users.
I confused a lot. It is never working until i restart my mongrel. I am
not able to predict, when the problem rises.
Yes,
My table have 'city' column. and i am able to save user data, when
he do registration.This problem occurs on only at particular
scenario.Just now I found a scenario, Which is
1.When i try to go to (action)registration page by clicking the link,
then the registration process works well.
2.When i try to go to same (action)registration page by redirecting
from another action(based on condition whether the user has logged in
or not), then the registration process fails when i do save the user.
Do you see anything in the log file when it gives undefined method
that might give a clue?
What deployment system are you using? Try running webrick and test
there, if the problem doesn't happen, then it's probably something
with your production deployment.
1.When i try to go to (action)registration page by clicking the link,
then the registration process works well.
2.When i try to go to same (action)registration page by redirecting
from another action(based on condition whether the user has logged in
or not), then the registration process fails when i do save the user.
Hmm, that's strange. The only thing I can think of is that the
redirection is setting a session variable or cookie or some other
persistent data that's messing up the process.
my scenarios are this,
1.When i try to go to (action)registration page by clicking the link,
then the registration process works well.
2.When i try to go to same (action)registration page by redirecting
from another action(based on condition whether the user has logged in
or not), then the registration process fails when i do save the user.
If i follow the first scenario, no problem.
If i follow the second scenario, problem rises.
If i follow the first scenario after did the second scenario,
problem rises still.
Looking for your billion dollar answer.
Thanks,

start the server and If i follow the first scenario, no problem.
restart the server and If i follow the second scenario, problem
rises.

Does it go away if you change cache_classes to true in development.rb?
Hi Frederick,
First of all thanks for your reply.Your answer is great and it
resolved my problem partially for the below one.

Yes, it gets away after I made cache_classes = true in development.rb.
But it has been fixed partially. Now what is the real problem is,
1.If I follow the first scenario as usual no problem and if I continue
the second scenario, it works(because of your suggestion).
2.If I directly do the second scenario, problem rises and If I
continue the first one then also problem rises. I could able to do
nothing then after.
Can you explain me why? looking for your reply Frederick,

This means you are confusing the dependencies mechanism. This usually
means that either:
- You have got plugins hanging on to references to one of your model
classes or instances of it
- You're explicitly requiring a class (ie using require), which
sidesteps rails' dependency stuff.
Fred,
I am using only one plugin simple_captcha. And I never explicitly
requiring a class in my app.
Now I am in new problem which is I am having model profile.rb and
table named profiles. If I tend to do like below,
