I would like to validate a number within a certain range. To first test that a entry is a valid number i use validates_numericality_of :my_number, :message =>''sorry, not a number'' to test if the number is within a certain range i use validates_inclusion of :my_number, :in => min..max, message => ''outside range!'' If the numericality test fails, I don''t want to do the second range test, otherwise both error messages will be displayed. At the moment, both tests with be performed regardless. Any ideas on how to do this? Thanks. -- Posted via http://www.ruby-forum.com/.
What would happen if you just take off the validates_numericality_of,
and left only validates_inclusion?
I know about two ways to solve your problem:
a) you can define a validate method in your method, do the validations
by yourself, and if you found any error, you can add them to the array
errors, example:
def validate
if (price == nil)
errors.add "There is not price!!!"
else if (price < 0)
errors.add "The price is negative!!!"
end
end
b) You can check what errors to display, in the view, by inspecting
modelobject.errors

I would like to validate a number within a certain range.
To first test that a entry is a valid number i use
validates_numericality_of :my_number, :message =>''sorry, not a
number''
to test if the number is within a certain range i use
validates_inclusion of :my_number, :in => min..max, message =>
''outside
range!''
If the numericality test fails, I don''t want to do the second range
test, otherwise both error messages will be displayed. At the moment,
both tests with be performed regardless. Any ideas on how to do this?
Thanks.

Hey Monty, if you goal is to validate that a field is within a certain range, then I would recommend using ''validates_inclusion''. -Conrad On 6/21/06, Rodrigo Dominguez <rails@rorra.com.ar> wrote:> > What would happen if you just take off the validates_numericality_of, > and left only validates_inclusion? > > I know about two ways to solve your problem: > > a) you can define a validate method in your method, do the validations > by yourself, and if you found any error, you can add them to the array > errors, example: > > def validate > if (price == nil) > errors.add "There is not price!!!" > else if (price < 0) > errors.add "The price is negative!!!" > end > end > > b) You can check what errors to display, in the view, by inspecting > modelobject.errors > > Rodrigo Dominguez > > Iplan Networks Datos Personales > rdominguez@iplan.com.ar rorra@rorra.com.ar > www.iplan.com.ar www.rorra.com.ar > 5031-6303 15-5695-6027 > > > -----Mensaje original----- > De: rails-bounces@lists.rubyonrails.org > [mailto:rails-bounces@lists.rubyonrails.org] En nombre de montyman > Enviado el: Mi?rcoles, 21 de Junio de 2006 10:14 a.m. > Para: rails@lists.rubyonrails.org > Asunto: [Rails] validation help > > I would like to validate a number within a certain range. > To first test that a entry is a valid number i use > validates_numericality_of :my_number, :message =>''sorry, not a number'' > > to test if the number is within a certain range i use > validates_inclusion of :my_number, :in => min..max, message => ''outside > range!'' > > If the numericality test fails, I don''t want to do the second range > test, otherwise both error messages will be displayed.
