Rails double submit -> double post -> duplicate data
Hi,
We are encountering occasions where users post twice or more a
form, basically we have detected two situations:
a) The user push twice enter
b) The user push double click on button "save" or "submit"
We consider that this becomes a problem when creating (because we
duplicate data) and we think that in some context it could become a
security issue

How do you detect if ActiveRecord ''update'' fails?
So I''m updating multiple model objects in one go with something like
this in my controller:
=> Photo.update(params[:photo].keys, params[:photo].values)
When the update fails due to validation errors, how do I detect it?
The Rails API says:
"If the save fails under validations, the unsaved object is still
returned."
So I can''t simply do this:

Encoding
What''s a good solution for fixing character encoding problems for
compatibility between ascii and utf-8? The database is postgres and
is encoded in utf-8.
Once in awhile there will be a compatibility error from strings from a
webform.
Is there a command to fix this besides using
a_string.force_encoding(''utf-8'')? Even this doesn''t seem to always
work either.

Hi,
In my model i want to overide the default find all for sorting purposes.
Is this possible or can this only be done in the control or by adding a
