Rails 3.1.3
I have a table ''Contribution'' having a column,
''price'' which must be
integers.
validate :price => true, :numericality => { :only_intger => true }
then, in creating a new Contribution DB, I need to check the user input
values. Of course, if the values are not valid, it needs to stay in the
same page showing error messages .
in ''contributions_controller.rb'',
respond_to do |format|
if @contribution.save
format.html { render action: "new", notice:
''Contribution was
successfully created.'' }
format.json { render json: @contribution, status: :created,
location: @contribution }
else
format.html { render action: "index" }
format.json { render json: @contribution.errors, status:
:unprocessable_entity }
end
end
hoping that the ''save'' method FAILS upon inputing string
values, for
example.
But interestingly, if I input, say, ''this'' in the input form,
it directs
to the next page and the ''0'' (an integer, though) value is
inserted in
the DB. I do not have any default value to ''price''.
Could anyone point out any mistakes that I am making here?
Thanks in advance.

I do not have any default value to ''price''.If you pop open a Rails console and type: ''this''.to_i What result do you get? Yep - zero is an integer. Rails casts the values from params to map to the DB fields, so if you want validate the values the user typed rather than the values Rails has translated them to, you may need to write a custom validation and check the "before_typecast" value. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hi All I am a newbie to this community. I recently published a gem called event_watcher for one of my project http://github.com/zzurang/event_watcher It is a simple dsl thing that is designed to help monitor certain function calls I wonder if I can get some feedback or advise in general Thanks -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

The line in your model should look like this validates :price, :numericality => { :only_integer => true } (note the plural ''validates'' rather than ''validate'' - they do two quite different things!) --Matt Jones -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

It should have been validates :price, :presence => true, ... and plural, yes, it reminds me Rails like plural nouns.
