Please help. I would like to assign a java variable to a ruby instance variable.
Thanks in advance for any help on this. I would like to search my DB for records using a Model.where request... Using jquery I have access to the text within the select option chosen from a drop box. Now, if only I could take this text and assign it to a ruby instance variable, such as @brand.... I could then insert the value into the ''where'' request and pull the records corresponding to the selected option. It seems possible to assign a ruby variable to a jquery var, but not the other way around. Is there, or could there be, a ruby function to help with this?

You will need to respond to an xhr request in your controller and return whatever result you need in Rails. From the jQuery (JavaScript) side, you''re doing a post request, just not refreshing the page as you do so.

You can do that with the Gon gem. https://github.com/gazay/gon -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

@ALPHA BLUE, Are you sure, it seems gon only allows for importing ruby/rails variables into Javascript, and not the other way around?

Re: Please help. I would like to assign a java variable to a ruby instance variable.
Sorry about that - I corrected it above. You can set your own instance variables using: self.instance_variable_set(:@var_name, value) Which will allow you to create dynamic variables. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Re: Please help. I would like to assign a java variable to a ruby instance variable.
Here''s an example for you:
class Dynamic
def initialize(variable,value)
@var,@val = variable,value
end
end
test = Dynamic.new(''somevar'', '''')
test.instance_variable_set(:@brand, ''You see my value'')
x = test.instance_variable_get(:@brand)
p x
