Ruby on Rails: Create doesn't work. Data doesn't insert to database -

two simple model:

record

class record < activerecord::base has_many :comments validates :title, presence: true, length: { minimum: 5 } end

comment

class comment < activerecord::base belongs_to :record end

in viewer

<h2>add comment: </h2> <%= form_for([@record, @record.comments.build]) |f| %> <p> <%= f.label :commenter %><br> <%= f.text_field :commenter %> </p> <p> <%= f.label :body %><br> <%= f.text_area :body %> </p> <p> <%= f.submit %> </p> <% end %>

in controller

def create @record = record.find(params[:record_id]) @comment = @record.comments.create(comment_params) logger.debug "comment check: #{@comment.attributes.inspect}" redirect_to record_path(@record) end

logger information:

when create comment, info doesn't write database suggestion? way, why each logger info has double output?

try adding accepts_nested_attributes_for :comments record model
