Hi,  
This is my migration:

class CreateSampleForms \< ActiveRecord::Migration  
def self.add\_data  
SampleForm.create(:name =\> ‘Default (Empty)’, :f\_type =\> ‘Default  
(Empty)’, :description =\> ‘Use this template to create a blank form.’)  
end

def self.up  
create\_table :sample\_forms do |t|  
t.string :name, :null =\> false  
t.string :f\_title  
t.text :description

```
  t.timestamps
end

self.add_data

```

end

def self.down  
drop\_table :sample\_forms  
end  
end

While migrating, it gives the error ‘undefined method f\_title=’. I first  
thought ‘title’ was reserved so I renamed it to ‘f\_title’. When I remove  
it,  
the process starts over with the description attribute.

Try this:

class CreateSampleForms \< ActiveRecord::Migration  
def self.add\_data  
SampleForm.create(:name =\> ‘Default (Empty)’, :f\_type =\> ‘Default  
(Empty)’, :description =\> ‘Use this template to create a blank form.’)  
end

def self.up  
create\_table :sample\_forms do |t|  
t.string :name, :null =\> false  
t.string :f\_title  
t.text :description

```
  t.timestamps
end
SampleForm.reset_column_information
self.add_data

```

end

def self.down  
drop\_table :sample\_forms  
end  
end

Hi,  
Rails doesn’t like the model name SampleForm.

I created a scaffold called Tent with the same attributes which does  
work.
