generator has_many results result belongs_to generator
when run rails console : result.find(1) , generator_id= nil. why ??? when i'm creating data , routes : localhost:3000/generator/1/results/new
it has got no error following code. how come when have in generator/index.html
<% generator.results.each |result| %> <td><%= result.ncbi_ref_seq %></td> <td><%= result.genome_sample %></td> <td><%= result.binding_times %></td> <%end%> they're empty. whereas @generators.each |generator| gives me values of generator. in other words, result's value belonging generator empty generator values shown. want have generators , result value shown. can some1 me ?
