First, what I wanna do is:

Have a page where I must write a name and choose a option on a select…  
The “nome” is a string of the Class Perfil and “acesso” is a string of  
the Class TipoAcesso.

TipoAcesso belongs\_to Perfil  
Perfil has\_many TipoAcesso

I’ve created 3 TipoAcesso on the Rails Console, where those TipoAcesso  
don’t will change, the user just choose one of them.

Then I got this error message:

> > > > >

NoMethodError in PerfisController#create

You have a nil object when you didn’t expect it!  
The error occurred while evaluating nil.call  
\<\<\<\<\<

With this respective code:

> > > > > Perfis Controller\<\<\<\<\<\<\<\<

class PerfisController \< ApplicationController  
def index  
end

def lista  
@perfis = Perfil.all

```
respond_to do |format|

  format.xml { render :xml => @perfis }
end

```

end

# GET /tipo\_acessos/1

# GET /tipo\_acessos/1.xml

@perfil = Perfil.find(params[:id])

end

respond_to do |format|

```

end

  else

    format.xml { render :xml => @perfil.errors, :status =>

```

:unprocessable\_entity }  
end  
end  
end

# PUT /tipo\_acessos/1

# PUT /tipo\_acessos/1.xml

def update  
@perfil = Perfil.find(params[:id])

```
respond_to do |format|
  if @perfil.update_attributes(params[:perfil])
    flash[:msg] = 'Perfil editado com sucesso.'
    redirect_to :action => 'show'
  else

end  
end

# DELETE /tipo\_acessos/1

# DELETE /tipo\_acessos/1.xml

def destroy

```
respond_to do |format|

  format.xml { head :ok }
end

```

end

end

## Detalhes do perfil \<%= @perfil.nome %\>

####

Tipo de acesso: \<%= @perfil.acesso %\>

\<%= link\_to 'Editar', :action =\> 'edit' %\>

## Criação de perfil

\<% form\_for :perfil, :url =\> {:action =\> ‘create’} do |form| %\>

\<%= form.label :nome, 'Nome' %\>

\<%= form.text\_field :nome %\>

\<%= form.label :acesso, 'Tipo de acesso' %\>

\<%= select :acesso, :acesso.id, TipoAcesso.find(:all).collect{|tipo| [tipo.acesso, tipo.id]}, {:prompt =\> 'Escolha um acesso'} %\>

\<%= form.submit “Criar” %\>  
\<% end %\>

> > > > > > > > > Model Perfil\<\<\<\<\<\<\<\<\<\<\<

class Perfil \< ActiveRecord::Base  
validates\_presence\_of :nome, :message =\> “deve ser preenchido.”  
has\_many :tipo\_acesso  
end

> > > > > > > > > Migrate Perfil\<\<\<\<\<\<\<\<\<\<\<

class CreatePerfis \< ActiveRecord::Migration  
def self.up  
create\_table :perfis do |t|  
t.string :nome  
t.string :acesso  
t.timestamps  
end  
end

def self.down  
drop\_table :perfis  
end  
end

> > > > > > > > > > > > > Model TipoAcesso\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<

class TipoAcesso \< ActiveRecord::Base  
belongs\_to :perfil

end

> > > > > > > > > > > > > > Migrate TipoAcesso\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<

class CreateTipoAcessos \< ActiveRecord::Migration  
def self.up  
create\_table :tipo\_acessos do |t|  
t.string :acesso  
t.timestamps  
end  
end

def self.down  
drop\_table :tipo\_acessos  
end  
end

* * *

Then I’ve change the method “create” of PerfisController

from:

> > > > >

def create  
@perfil = Perfil.new(params[:perfil])

```
respond_to do |format|
  if @perfil.save
    flash[:msg] = 'Perfil criado com sucesso.'
    redirect_to :action => 'show'
  else
    format.html { render :action => "new" }
    format.xml { render :xml => @perfil.errors, :status =>

```

:unprocessable\_entity }  
end  
end  
end  
\<\<\<\<\<

to:

> > > > >

def create  
@perfil = Perfil.new(params[:perfil])

```
respond_to do |format|
  if @perfil.save
    format.html do
      flash[:msg] = 'Perfil criado com sucesso.'
      redirect_to :action => 'show'
    end
    format.xml { render :xml => @perfil.to_xml }
  else
    format.html { render :action => "new" }
    format.xml { render :xml => @perfil.errors, :status =>

```

:unprocessable\_entity }  
end  
end  
end  
\<\<\<\<\<

And now i’m getting the following error message:

> > > > >

ActiveRecord::RecordNotFound in PerfisController#show
