Hello , plz i need your help : here is my module :

analyse.py

    from openerp import addons 
    from osv import fields, osv
    import time

    class analyse(osv.osv):
        _name='analyse'
        _description='fiche danalyse du patient'

        _columns={


                    'name' : fields.char('pat', size=34 ,required=True),                


        }
    analyse()

and here is my XML file : analyse.xml

<?xml version="1.0" encoding="utf-8"?>
<openerp>
    <data>


    <record model="ir.ui.view" id="analyse_tree_view">
    <field name="name">analyse.tree</field>
    <field name="model">analyse</field>
    <field name="type">tree</field>
    <field name="arch" type="xml">
        <tree string="Analyse" version="7.0">


                                                <field name="name" />




        </tree>
    </field>
</record>
<record model="ir.ui.view" id="analyse_form_view">
        <field name="name">analyse.form</field>
        <field name="model">analyse</field>
        <field name="type">form</field>
        <field name="arch" type="xml">
            <form string="Analyse" version="7.0">



                                            <group colspan="4" col="4" string=" Fiche d'analyse">
                                                <field name="name" />

                                        </group>


            </form>
        </field>
</record>



<record model="ir.actions.act_window" id="analyse_form_1">
    <field name="name">analyse</field>
    <field name="res_model">analyse</field>
    <field name="view_type">form</field>
    <field name="view_mode">tree,form</field>
</record>

<menuitem id="analys" name="Analyse"  parent="menu_patients_parent1" action="analyse_form_1" sequence="3"/>



</data>
</openerp>

PS: menu_patients_parent1 , refers to a parents created in another .XML file , befor i added the analyse.py and analyse.XML the module worked just fine , but now while installing i get the following error :

ProgrammingError: ERREUR: erreur de syntaxe sur ou près de « analyse » LINE 1: COMMENT ON COLUMN analyse."name" IS 'pat' ^
