How can I show Category in stock move tree. This is my coding.

My view file.

    <field name="model">stock.move</field>

try this files.

your .py file

class custom_stock_move_tree(osv.Model): #their is different b/w osv.Model and osv.osv_memory before to use it read it's usage

    _inherit = 'stock.move' # if you want to add data in existing module use inherit  
    _columns = 
    {    
        'categ_id': fields.related('product_id', 'categ_id', type='many2one' ,relation='product.category', store=True, string='Product Category'),              
    }

Your view.xml file

<record id="royalfood_stock_move_tree_view" model="ir.ui.view">
<field name="name">stock.move.tree</field>
<field name="model">stock.move</field>
<field name="inherit_id" ref="stock.view_move_tree" />
<field name="arch" type="xml"> 
    <xpath expr="//field[@name='product_id']" position="before">  
        <field name="categ_id" groups="base.group_user"/>   
    </xpath> 
</field>

After this see your Stock Move Tree view.
