Hi

Im using Multiple Forms and Multiple tables +One Model +One Controller in my rails application

I have 5 forms(5 stages) to create my rails application.

1st form: to enter the data and click the next button.To get the values in session.

2nd form: to enter the data and click the next button.To get the values in session.

3rd form: to enter the data and click the next button.To get the values in session.

4th form: to enter the data and click the next button.To get the values in session.

5th form: to enter the data and click the create button.To store the data to corresponding table.

Controller code:

I do not really understand, what you are doing here, but:

You are using "else if" without a condition several times, beneath the fact that the correct ruby syntax is elsif

Then Ruby would interpret the following line: @stage = params[:stage].to_i as condition and the outcome of this is most likely not what you would expect.

And all those "end' show too, that the structure is a bit weird.

I think, what you want to do would need something like this:

def wizard if params[:stage].nil?   ...   elsif params[:stage].to_i == 1   ...   elsif params[:stage].to_i == 2   ...   else   ...   end   render :template => 'wizard\\stage'+@next_stage.to_s end

Hi Thorsten Müller

i got bugs:

NoMethodError in WizardController#wizard

You have a nil object when you didn't expect it!
You might have expected an instance of ActiveRecord::Base.
The error occurred while evaluating nil.[]

Hi

I follow ur way and i used the above code but i got the bugs

can’t convert nil into String

code

Well, if an application gives you an error, it usually wants to say something. In this case it expected a string, and got a nil. You didn’t include what line it choked on, but I guess it’s the render one. It’s telling you that params[:stage] is nil, so you need to handle that.

‘wizard/stage’+(params[:stage] || ‘’)

And please please please, do yourself a favor, read some books on Rails first. There are some nice ones out there and most of them have a nice introduction to basic programming principles. Your code is just completely unmaintainable.
