ArgumentError (wrong number of arguments (1 for 0)):

Hi folks:

In my create action I´m getting this messagge:

ArgumentError (wrong number of arguments (1 for 0)):

What does this means? Do i´m passing more or less parameters than needed? Any guidance would be very appreciated

I´m using a form with 3 models, including a model to attach images with Paperclip

The create action is pretty standard:

def create @property = Property.new (:property) end

These are the parameter:

Processing PropertiesController#create (for 127.0.0.1 at 2009-03-05 00:06:10) [POST]   Parameters: {"commit"=>"Incluir Propiedad", "property"=> {"garage"=>"1", "purpose"=>"Venta", "front"=>"25", "rent_price"=>"1300", "baths"=>"1", "contact"=>{"company"=>"La cantera del señor Rajuela", "cell"=>"0123456789", "phone"=>"0123456789", "contact_type"=>"Propietario", "fax"=>"2255-14510", "first_name"=>"Pedro", "last_name"=>"Picapiedra", "email"=>"ppicapiedra@piedradura.com"}, "image_attributes"=> [{"photo"=>""}, {"photo"=>""}, {"photo"=>""}, {"photo"=>""}, {"photo"=>""}, {"photo"=>""}, {"photo"=>""}], "this_type"=>"House", "description"=>"casa grande", "rooms"=>"1", "localization"=>"en las afueras", "exclusive"=>"0", "address"=>"100 norte del sur", "lot_area"=>"1800", "const_area"=>"500", "province"=>"San Jose", "sell_price"=>"500000", "min_price"=>"150000"},"authenticity_token"=>"225a4b100cfce5efa6781ab2eabddc8b2d9690c7"}

I suspect the line raising that is somewhere inside active record.
Assuming Property is an ActiveRecord method it's expecting a hash to
be passed ( eg params[:property] ) but you're just passing the symbol
property.

Thanks Frederick:

Sorry I mistyped the method definition, the correct is:

def create @property = Property.new (params[:property]) end

Given that I had the error mentioned.

Any thoughts?

Not without a stack trace (ruby should warn you that you should write
Property.new(params[:property]) but I don't think that would change
much).

Did you pick a method name that Rails is already using by any chance?

khiltd:

Well I think that´s a possibility, but how could I check that?

Thanks Frederick I really appreciate your continued support through this list.

That to me looks like your code actually reads params(:property)
rather than params[:property]

Ok. Solved The problem was that I put a white space between params and the brackets as: params [:property] instead of params[:property]. Thanks Fred and khiltd.
