storing complex records in rails database with form_tag

问题

I'm trying to save records in a database. Many of the column values will be taken from a http request to an api.

I have a text field and some check boxes along with the session_id in the form which will be persisted. this is posted from another controller (form_tag('results#store'))to an action called store in the results controller.

Store action:

def store

  query = query_preprocesser(params[:query]) # this is in a helper

  ## example of resArray ##
  #resArray = [[{:engine => "bing, :results => [{:Description => "abc", :Title => "def"}, {:Description => "ghi", :Title => "jkl"}]}, {etc},{etc} ],[{:eng...}]]

  resArray = getResults(query) # Also a helper method returning an array of up to 3 arrays
  resArray.each do |engine|
  db_name = engine[:engine]
      engine[:results].each do |set|

        res = Result.new(
        :session_id => params[:session_id], 
        :db_name => db_name,
        :query => query,
        :rank => set[:Rank],
        :description => set[:Description],
        :title => set[:Title],
        :url => set[:Url] )
    res.save!
   end
  end

res.each do |res|
    res.save
end
#Result.new(:session_id => params[:session_id], :db_name => "Bing", :query => "Whats the story", :query_rank => 1, :title => "The Title", :description => "descript", :url => "www.google.ie",:query_number => 1)

respond_to do |format|
      format.html { redirect_to pages_path }
      format.json { head :no_content }
    end
end

My routes are resources :results

Form:

Rake routes:

       store POST   /pages(.:format)             results#store
      results GET    /results(.:format)           results#index
              POST   /results(.:format)           results#create
   new_result GET    /results/new(.:format)       results#new
  edit_result GET    /results/:id/edit(.:format)  results#edit
       result GET    /results/:id(.:format)       results#show
              PUT    /results/:id(.:format)       results#update
              DELETE /results/:id(.:format)       results#destroy
        store POST   /pages(.:format)             results#store
        pages GET    /pages(.:format)             pages#index

I keep getting redirected to the new action in Results controller. The helper methods aren't even being executed. I'm a past master at over complicating things, can anyone help unravel this for me?

回答1:

Do you have a route set up for the store action? If you do then you should use the url helper for it in your form tag:

form_tag( results_store_url )
