Odoo 9.0 Website tutorial - Selling Courses

I have a question about the 'Selling Courses' part of the Odoo tutorial.

This is the output of the server when I want to open the website. Apparantly there is a problem with the parsing of the xml file. But I think the cause has to be that the "website_sale.categ_others" is just not recognised. Or perhaps it has something to do with the depends import in the __openerp__.py file.

At this point I've gone from copy/pasting every change in the code to my files, but this has shown no effect.

Apparantly I'm missing something here. I've included all code that I currently have at the bottom of this question.

Server output file:

The solution given by Mukarram Pasha is valid also for Odoo 10 with the following modifications:

__manifest__.py (works without module 'base')

...
    # any module necessary for this one to work correctly   
    'depends': ['website_sale'],  
...

data.xml (initial tag changed to odoo in v10)

<odoo><data>
<record model="product.public.category" id="category_courses">
    <field name="name">Courses</field>
    <field name="parent_id" />
  </record>
</data></odoo>

Thanks you Mukarram.

Make changes to your following files:

In __openerp__.py file:

remove 'mail' dependency since 'website_sale' already has its own mail module.

...
    'category': 'Tutorials',        
    'version': '0.1',     
 
    # any module necessary for this one to work correctly        
    'depends': ['base', 'website_sale'],     

    # always loaded        
    'data': [                
        'security/ir.model.access.csv',                
        'views/views.xml',                '
        'views/templates.xml',                
        'data.xml',    
    ],        

    # only loaded in demonstration mode        
    'demo': [                
        'demo/demo.xml',     
    ],
}

In data.xml file:

remove ref="website_sale.categ_others"

<openerp>
     <data> 
         <record model="product.public.category" id="category_courses">   
             <field name="name">Courses</field>                      
             <field name="parent_id"/>             
         </record>        
    </data>
</openerp>

In views.xml file remove all views of academy.course since it is now inherited from 'product.template'.

I hope this will help. worked for me.
