I am new to Rails creating a new Rails app. My boss wants the index
page to have a text field to enter a case number. If the case number
exists then I need to open the edit page for that case number. If the
case number doesn''t exist then I need to create a new one.
The case_number is a text field of the table scenario, id is an
autoincrement integer.
I created an index.rhtml page with a form that pointed to an eval method.
My eval method resembles this:
@case_number = @scenario.case_number
@scenario = Scenario.find(@case_number)
if @scenario
redirect_to :action => ''edit'', :id => @scenario.id
else
flash[''notice''] = ''Unable to find Scenario,
creating a new one.''
render_action ''new''
end
end
I have tried different combinations of redirect_to and render_action.
I am currently pulling my hair out trying to solve 2 main issues.
1. I can''t find the correct scenario given and existing case_number
and Rails goes to the new page. what am I doing wrong?
2. when Rails sends me to the new page I don''t get a clean new page I
get notified that some of my fields are blank. How can I tell Rails to
ignore those errors when I do this?
Am I even going about this the right way?
Hi, I''m hardly an expert at this myself, so take the following with a grain of salt.> > My eval method resembles this: > @case_number = @scenario.case_numberI''m not clear on what is happening above, would have to see the index.rhtml - it seems to assume that a scenario already has been found/created somehow.> @scenario = Scenario.find(@case_number)I _believe_ that you want to do @scenario = Scenario.find(:first, :conditions => [ "case_number = ?", @case_number]) --ryan

I appreciate the help so far, but I am still having problems.
Here is some information which I didn''t realize you guy might need to
help me. Also if has a way to stop duplicating the code to populate
the @team_array and @p_array, I tried moving it to a subfunction but
it didn''t work, I am thinking I lost scope.
My model/scenario.rb
class Triage < ActiveRecord::Base
validates_format_of :case_number, :with=>/[a-zA-Z]{5}\d{5}/,
:message=>"must be 10 characters, 5 alphabetical followed by 5
numberic"
validates_uniqueness_of :cr_number
validates_length_of :sw_version, :within=>1..20, :message=>"must be
between 1 and 20 characters"
validates_length_of :subcode, :within=>1..36, :message=>"must be
between 1 and 36 characters"
belongs_to :team
belongs_to :pname
has_many :note
end
Except from scenario_controller.rb
...
def new
@teams = Team.find_all
@team_array = [["Select Team",""]] + @teams.map {|u|
[u.teamname , u.id]}
@p_codes = Pname.find_all
@p_array = [["Select Code",""]]+ @p_codes.map {|u|
[u.p_code+"
"+u.p_name, u.id]}
@scenario = Scenario.new
rescue
end
def create
@teams = Team.find_all
@team_array = [["Select Team",""]] + @teams.map {|u|
[u.teamname , u.id]}
@p_codes = Pname.find_all
@p_array = [["Select Code",""]] + @p_codes.map {|u|
[u.p_code+"
"+u.p_name, u.id]}
@scenario = Scenario.new(@params[:scenario])
if @scenario.save
flash[''notice''] = ''Scenario was successfully
created.''
redirect_to :action => ''list''
else
render_action ''new''
end
end
def edit
@triage = Triage.find(@params[:id])
@notes = @triage.note
@teams = Team.find_all
@team_array = [["Select Team",""]] + @teams.map {|u|
[u.teamname , u.id]}
@p_codes = Pname.find_all
@p_array = [["Select Code",""]] + @p_codes.map {|u|
[u.p_code+"
"+u.p_name, u.id]}
end
def eval
@scenario = Scenario.find(@params[:case_number])
if @scenario
redirect_to :action => ''edit'', :id => @scenario.id
else
flash[''notice''] = ''Unable to find Scenario,
creating a new one.''
redirect_to :action => ''new''
end
end
...
Excerpt from index.rhtml is:
...
<%= start_form_tag :action => ''eval'' %>
<p><label for="scenario_case_number">Case
number</label><br/>
<%= text_field ''scenario'', ''case_number''
%></p>
<%= submit_tag "Scenario" %>
<%= end_form_tag %>
...
To clarify, when I redirect to new I am getting validation errors
saying the software version and subcode are still blank. I never get
the chance to fill in these fields before the validation takes place.
I want the result of the eval action to be a scenario=>new, fill in
the fields and submit or scenario=>edit, change the fields and submit.

It probably would have helped if I had inlcuded one of those .rhtml. Actually both use the same _form.rhtml. The code to build those list I have to propogate everywhere to prevent erorrs on my pages but I know that this is a bad coding practice, I tried moving the code to a method called populate, butthat didn''t work.

I enter a case number and submit. That should be routed to scenario=>eval, which should either start a new scenario if a scenario with that case number doesn''t exist or edit the existing scenario. What I am getting is the scenario=>create displayed with my SW version and subcode fields highlighted because they didn''t pass validation. - Michael

( you need a scenario to edit after all ) another suggestion... dont worry about your selects for now... get it working without them... then add them in... your problems are really getting buried behing a bunch of unused code that isnt conceived of properly... i''d suggest spending some time reading the documentation and apis... you might have to dig a bit but you will find a lot of useful information... i spent my first two weeks with rails trying really small little things and exploring the api and really learning different way to do things right... _______________________________________________ Rails mailing list Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org http://lists.rubyonrails.org/mailman/listinfo/rails
