Re: [Rubyonrails-ug] controller problem !

Mon, 12 Oct 2009 13:54:13 -0700 

Falls @depth = params[:books][:depth] noch so in Deinem Controller steht
kann es auch nicht gehen. params[:books] gibt es nicht und ist somit nil.

ja das stimmt es heisst f.submit ;-) bin jetzt zwar ein schritt  
weiter aber nicht ganz ;-)



das problem ist das es zwar für source einwandfrei funktioniert aber  
für die anderen variablen leider nicht ! ich hab jetzt die andere  
variablen auskommentiert und gebe es in der view aus und prompt  
kommt der fehler wieder :

You have a nil object when you didn't expect it!

meine view sieht so aus :

<% form_for :book do |f| %>
<p>
<label> :source </label><br>
<%=f.text_field :source %>
</p>
<p>
<label>:depth </label><br>

</p>
<p>
<label>:parentId </label><br><br>
<%= f.text_field :parentId %>
</p>
<p>
<%= f.submit "Create" %>
</p>

<% end %>
<%= @source %>
<%= @depth %>
<%= @destination %>
<%= @dest_space %>
<%= @parentId %>


und mein controller so :

class BooksController < ApplicationController
def index

require 'little_helpers_spezial'
#confluence = Confluence::Server.new("https://spoi.telekom.de/info";)

#confluence.login(Einloggen_spezial::X_login,  
Einloggen_spezial::X_pwd)


@source = params[:book][:source]
@depth = params[:books][:depth]


#x = Little_Helpers_spezial.make_ready_for_export(confluence,  
source , depth)


@destination = params[:book][:destination]
@dest_space = params[:book][:dest_space]
@parentId = params[:book][:parentId]


#Little_Helpers_spezial.save(confluence, x, destination,  
dest_space,parentId)


end
end

Subject: Re: [Rubyonrails-ug] controller problem !

sorry, es muss f.submit und nicht f.submit_tag heissen.


Falls es wieder nicht klappen sollte, schick mir mal den Ausschnitt  
aus dem log, welcher beim abschicken des Formulars generiert wird.  
Mich interessiert vor allem der params-Hash.
