Hi
I have a field called "cost":
<%= f.text_field :cost, :size=>2, :maxlength=>4 %>
I want to check that user enter numeral value and this value is integer
In post.rb (model):
def cost_validate_int
errors.add_to_base("Error message") unless cost.is_a?(Fixnum)
puts "### #{cost}: "+cost.class.to_s
end
When I enter in field 100 I get:
### 100: Fixnum
when I enter 10.1:
### 10: Fixnum
when I enter 'asdf':
### 0: Fixnum
I completely can't understand what happen. In migration:
t.integer :cost
I think ActiveRectord converts value to Fixnum because in migration this
field signed as integer
Can I in some way check cost value in model (value should be numeral and
integer)?
Thanks in advance!
