Hello everyone, I added two new fields (many2one, many2many) to the form but i can see that it has the different view. and I need to make the many2many field appear same as one2many(with no "add" button, and have the link "add an item").

You can use widget='one2many' in xml. This will change many2many form view to one2many as you want.

For Example:

<field name='your_many2many_field' widget='one2many'/>

thank you Sudhir. yes, you right. but it's not appear the same form/window as many2many after I click on "add an item". what I want to do is just change the view and everything is still many2many.

You can define internal tree view inside m2m field with editable option.

You can use widget="one2many_list" in the xml. This will change many2many field form view or many2one field form view to one2many field view as you want.

For Example:

Example 1: For many2many Field 

<field name="fieldname_many2many" widget="one2many_list"/>

Example 2: For many2one Field

Declaration in .py:

  'datas_field1':fields.many2one("ir.attachment",  "DATAS Field")

Declaration in .xml:

 <field name="datas_field1"  readonly="1" widget="one2many_list">
                       <tree>
                        <field name="datas_fname"/> 
                        <field name="datas"/>                          
                        </tree>
  </field>
