Ruby On Rails: Using parameters from the new controller function in the create controller function -

Text after "

I am passing in: number as a parameter and then in the code in the controller variable @test_suite_num> before_filter .

In the function in my new controller, I use the variable @test_suite_num to filter a table named test to count the entries whose ID matches To get @test_suite_num I use this count to generate the appropriate number of child resources; test_run .

I do this for create , but for some reason I get a zero error. I use these variables in forms that @test_suite_num depend on. I am assuming that after making any time, no parameter is taken, the variable is never started. ? How can I use @test_suite_num in function

controller code:

  before_filter: get_number ,: only => [: New: create] get_number @test_suite_num = params [: number] end   
 new  
  def new @test_suite_run = TestSuiteRun.new @tests = Test.find (: all ,: position = & gt; {test_suite_id = & gt; @test_suite_num}) test cases.times.times test_run = @ end end test_suite_run.test_runs.build   
 Create  
  DEF = TestSuiteRun.new @test_suite_run create (parameter [: test_suite_run]) @tests = Test.find (: All ,: position => {: test_suite_id = Gt; @test_suite_num}) @ test.count.times test_run = @ test_suite_run.test_runs.build (parameter [: test_suite_run]) end if @ test_suite_run.save flash [: success] = "Run Added successfully" redirect_t O test_suite_runs_path (@test_suite_run) and submit 'New End End   
 Edit:  
 I have just started using ROR, so my style really Is dirty. Although my problem is still standing, my problem is that in my form, I am using @Tests, which I started with the parameter passed. I can see the form properly, but when I submit, I get:  
  Showing / Users / vsp / Documents / rails_projects / web_db / app / views / test_suite_runs / _form.html.erb where Row # 13 has been raised: The id has been called for zero, which will be 4 by mistake - if you want the id of zero in fact, use the object_id extracted source (approximately # 13 line): 10: 11: & lt;% = f.fields_for: test_runs do | Builder | & Gt%; 12: 13: Test <% = @tests [@i] .id% & gt; & Lt; Br> & Lt; Br> 14: 15: & lt;% = Render "Partial" ,: f => Builder% & gt; 16: & lt; Hour & gt; Obviously this means that the parameter is not getting on the controller [number] is something wrong with my create function

 Looking through this, it's just all my In the form there is text_input areas.   
 
 
 You're really doing something weird Rather than assigning  @test_suite_num  for an example variable and instead of putting it in a garter method (which is very weird and weird), get rid of that  before_filter  and completely Remove the method from In fact, do not even use  @test_suite_num  because it seems that you are not using it.  
 Instead, just use  params [: number]  as you used it for yourself.  
  If this does not work, then  puts params.to_s  in your texture and let us know what happens when you submit a form. (Also, look as a footnote: What are the example variables in Ruby, because it seems that you are misusing them.)
