Just define the field in the view with an attrs="{'invisible': domain}"

where domain is a valid Odoo domain using fields of the view that when get value True the field will be invisible else the field is displayed in the form, your domain could be something like [('customer_id','=', False)]

this means that the new field is invisible when there is no customer selected in the corresponding customer box

Dear Jihen BEN ALI,

try this code may be used for you.

<field name="your field name" groups="group id"/>

or

You should create security file and assign that group in fielda.

If you dont know how to create security file then follow below step and hope you will get answer

You have to create ir.model.access.csv in your module, I suggest you to create a security folder and put security related file there

Like security/ir.model.access.csv and security/given_any_name_security.xml

Change in openerp.py file like 'security/given_any_name_security.xml, 'security/ir.model.access.csv'

Inside xml file you sholud create group like

<?xml version="1.0" ?>

<openerp>

<data noupdate="1">

<record model="ir.module.category" id="module_school_category">

<field name="name">School</field>

<field name="description">School</field>

<field name="sequence">16</field>

</record>

<record id="group_school_user" model="res.groups">

<field name="name">User</field>

<field name="category_id" ref="module_school_category" />

</record>

<record id="group_school_manager" model="res.groups">

<field name="name">Manager</field>

<field name="implied_ids" eval="[(4, ref('group_school_user'))]" />

<field name="category_id" ref="module_school_category" />

<field name="users" eval="[(4, ref('base.user_root'))]" />

</record>

</data>

</openerp>

Inside csv file you should give the permission like

id,name,model_id:id,group_id:id,perm_read,perm_write,perm_create,perm_unlink

access_student_student_manager,student.student,model_student_student,group_school_manager,1,1,1,1

access_student_student_user,student.student,model_student_student,group_school_user,1,1,0,0

access_hobby_hobby_manager,hobby.hobby,model_hobby_hobby,group_school_user,1,1,1,1

access_hobby_hobby_user,hobby.hobby,model_hobby_hobby,group_school_user,1,1,0,0

Now in your view file to add group in field like

<field name="many2one_field" groups="module_name.group_id"/>

here groups define the value of module_name.group_id that means

group_id: group id which is define in security xml file

Example:

<field name="hobby_id" groups="school_management.group_school_manager"/>

Finally update the module

Hope this code is usefully for you.

Thanks & Regards
