CakePHP on adding a belongsTo table not found?

I have a CakePHP model which looks like this (and works fine):

class Paper exten开发者_开发问答ds AppModel {
      var $name = 'Paper';
      var $displayField = 'id';
}

This gives no error since I have a papers table in my database.

When I change the model to so (I simply add that last line):

class Paper extends AppModel {
      var $name = 'Paper';
      var $displayField = 'id';

      var $belongsTo = 'User';
}

I get the error:

Missing Database Table

Error: Database table ps for model Papers was not found.

Notice: If you want to customize this error message, create app\views\errors\missing_table.ctp

What could be going wrong that CakePHP suddenly assumes some first and last character nomenclature on adding a belongsTo line?

EDIT

I may be wrong with this, but shouldn't the error say model Paper? It's saying Papers instead. This happens after adding the belongsTo statement. Is this where the error is?

I managed to fix this issue.

Simply put, model-model links are not a one-way street as the CakePHP documentation calls it.

For example if model A belongsTo model B, then model B MUST hasOne or hasMany model A.

In my case, syntax at the receiving end was faulty.
