search for: case_id

...l case (I realize I could just set a flag to separate them, but there is a good reason to separate them), but both need to be related to the children table. Here is the model code: class Case < ActiveRecord::Base end class Registered < Case has_many :children, :foreign_key => "case_id" end class Initial < Case has_many :children, :foreign_key => "case_id" end class Child < ActiveRecord::Base belongs_to :initial belongs_to :registered end When I attempt to access the children attribute via an Initial object I get an unknown column exception and...

...d "redirect_to" when working with .rhtml forms in the Controller?? When is it appropriate to use these? ? Second - ?Why do I sometimes have to use a while loop to access my queried data in the .rhtml form?? Example: ? Controller-Edit Method @edit = Cause.find(:all, :conditions => "case_id = ''#{@caseid}''") ? View-Edit.rhtml <h2>Editing Case <%= @edit.case_id %> ?

I am instead searching by my session variable (case_id), which I understand returns an array, so I need the loop: @caseid = session[:case_id] @report = Report.find(:all, :conditions => "case_id = ''#{@caseid}''") Could the presence of a do loop cause the datetime_select to not function properly? Any help always appr...

Hi, After I''ve saved, I want to display the Description from the Codes table that corresponds with the ID in the Cause table. Rails doesn''t seem to like that, because on my form, I have two sets of data in combo boxes that come from the Codes table.

I''m trying: @master_id = @params[''master_id''] in the components controller but it is not working. ==== Details: In my calling view I have: <%= h(@opportunity.id) %> <div

...h I can use packages such as these on un-weighted data there does not appear to be a facility to take account of weighted data. I am a statistician working for a Market Research company where in many projects I work on weighted data. Typically, the data will be structured in the following manner: Case_id y x1 x2 x3 x4 weight 1 5 3 4 1 4 0.345 2 3 4 3 1 5 0.543 3 2 2 3 3 3 1.456 4 4 4 2 4 3 0.345 5 3 3 4 3 2 1.200 . . etc The above data is fictional. Where y is the dependent variable, and there are 4 independent variables (x1, x2, x3 and x4), and weight is the weighting factor variable....
