similar to: record validation based on controller method

I have a question about how ActiveRecord handles data types. When I enter text in a text_field (meaning, a field in the GUI) which belongs to a numeric field in the database, Active Record automaticly converts it to 0, because that''s what the to_f/to_i method of a string does. Is it also possible to have Active Record enforce the types, so that when you enter text for a numeric

Hi, there. I have two validations in the model: validates_numericality_of :value, :only_integer=>true, :allow_blank=>true validates_size_of :value, :is=>9, :message=>"must be 5-digit number", :if=>Proc.new{|u| u.value.is_a?(Numeric)} They work as expected except when the :value is character/string like "a" "abc", the second validation will also output

How would I use validations to ensure I either received a blank value or a ten digit number? If I set validates_length_of :field, :in => 0..10 then that would allow any value in-between. The allow_nil => true option does not seem to work. I''ve also tried using this with some combination of validates_numericality_of but cannot get it to work. Any help would be greatly

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

Hi, I am trying to validate a numeric value passed in from a form, which is saved in a MySQL db as decimal(9,2) Now problem is I need to ensure people don''t enter a form value like -. 003. In my validations, I have a validates_numericality_of check being done. Furthermore, in validate method, I have a check using an if statement such as : ((an_object[n].nil? or an_object[n] < 0) and

Is it possible to get the current Controller''s action from within the Model? I have a situation where I want a piece of validation to run on edits, but not on new creates. Thanks, - Mark -- Posted via http://www.ruby-forum.com/.

First of all, thanks for you time.

hi there. Here is the simple scenario: My active record connects to a table that contains an integer field. My form contains a text box that allows me to enter a value to get updated to the integer field. If anything gets entered that is anything other than a POSITIVE INTEGER, I want to display an error. I have noticed that if I create a new active record like @record =

I have a situation in which I want to validate a number is not zero. Both positive and negative values are acceptable, just not zero. validates_numericality_of has an :equal_to attribute, but I don''t see a :not_equal_to. I have not yet been able to find anyone who has discussed this. I did find information about custom validators, so I am now using a custom validator to check the field

Hi all - To avoid floating point issues, I''ve decided to store monetary values in cents in the database. However, the user will enter these in dollars and cents. Two questions: 1) How do I do the validation for the currency format? It looks like ActiveRecord truncates the cents since it thinks the field type is a Fixnum. Am I forced to do validation in the controller? 2) Where

Is there a way to use validates_numericality_of and still allow null values? I have a model with some optional values that can be nil, but if they''re present, they must be numbers. Will I need to construct a custom valiation for this, or is there some method built in? Seems like it would be a common enough need. Jeff -- Posted via http://www.ruby-forum.com/.
