Hi there,
I am going batty with this problem and was hoping someone could help me
out. I have a restaurant object that can have many boundaries (these are
kept in a separate table and consist of a lat and long attribute).
I have figured out how to pass multiple boundaries in the params hash
upon a new restaurant creation. The params hash looks as follows:
Parameters:
{"restaurant"=>{"sun_open(4i)"=>"13", ...,
"commit"=>"Submit
Restaurant",
"authenticity_token"=>"c319f495e108e4ef33881628b63f443c94bda27a",
"action"=>"validate_and_save",
"controller"=>"restaurants",
"boundaries"=>[{"lng"=>"-79.37759399414062",
"lat"=>"43.67581809328341"},
{"lng"=>"-79.39141273498535",
"lat"=>"43.677711435998695"}],
"image"=>[""]}
Now in my controller I need to create a boundary object for each lat/lng
in the hash. I would like to do something like this:
params[:boundaries].each do |boundary|
@restaurant.boundaries << Boundary.new(:lng =>
''lng'', :lat => ''lat'' )
end unless params[:boundaries].nil
However, I just can''t seem to be able to accomplish the task. I have
played around with it and either it never goes into the loop or I get an
error. Does anyone know what I need to do in the controller to correctly
retrieve and create the boundaries?
Thanks,
steve
