Hi… I have a select which I want to validate if a value is selected, otherwise not.
<%= f.collection_select :parent_id, Project.mainprojects.active, :id, :project_name, :include_blank => ‘Partproject?’, :allow_nil => true%>
how is the correct way…?
tried…in model if :project_id if :project_id? if :project_id.blank?
etc . etc. But nothing works…
so the name of the input is SOMETHING[parent_id] right?
then you have to validate
if self.parent_id.blank?

So what is the value of project_id that you are trying to test for? If you are not sure then have a look at the Rails Guide on debugging which will show you techniques that you can use to debug your code. Then you can find out what is the value of project_id and why your tests are not working.

Hi Colin..
<%= f.collection_select :parent_id, Project.mainprojects.active, :id, :project_name, :include_blank => 'Partproject?', :allow_nil => true%>
the project_id .. 1, 2 etc. or ""
"parent_id"=>"1" "parent_id"=>""

Hi Colin..
Please don't top post, it makes it difficult to follow the thread. Insert your reply at appropriate points in previous message. Thanks.

You said in your initial post that you were testing it in the model. What do you mean by "parent_id" => ""? In the model it should probably be an attribute self.parent_id, but in that case I would expect it to be nil if it is a foreign key.
If you are trying to test it in the controller then it depends what you are trying to do. Show us the code you have tried (for the action, not just one line out of context).
