    copied!<p>I tried to use many2many relational field in my custom module "notebook". Code is given below:</p> <p>notebook.py:</p> <pre><code>from osv import fields, osv import time class notebook(osv.osv): _name = "notebook" _description = "Simple Notebook" _columns = { 'title' : fields.char('Title', size=30, required=True), 'tag_ids': fields.many2many( 'hello', 'title', 'name', string="Tags" ), } notebook() class hello(osv.osv): _name = 'hello' _columns = { 'name':fields.char('Name',size=30), 'note_ids': fields.many2many( 'notebook', 'name', 'title', string="Notebooks" ), } hello() </code></pre> <p>notebook_view.xml:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;openerp&gt; &lt;data&gt; &lt;record model="ir.ui.view" id="notebook_form_view"&gt; &lt;field name="name"&gt;notebook.form&lt;/field&gt; &lt;field name="model"&gt;notebook&lt;/field&gt; &lt;field name="type"&gt;form&lt;/field&gt; &lt;field name="arch" type="xml"&gt; &lt;form string="Notebook"&gt; &lt;field name="title" /&gt; &lt;field name="tag_ids" widget="many2many_tags"/&gt; &lt;/form&gt; &lt;/field&gt; &lt;/record&gt; &lt;record model="ir.actions.act_window" id="action_notebook_form"&gt; &lt;field name="name"&gt;notebook&lt;/field&gt; &lt;field name="res_model"&gt;notebook&lt;/field&gt; &lt;/record&gt; &lt;menuitem name="NotebookParent" icon="terp-project" id="NotebookParent_menu" /&gt; &lt;menuitem name="NotesChild" parent="NotebookParent_menu" id="NotesChild_menu" /&gt; &lt;menuitem name="Header" parent="NotesChild_menu" id="Header_menu_mainform" action="action_notebook_form" /&gt; &lt;/data&gt; &lt;/openerp&gt; </code></pre> <p>hello_view.xml:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;openerp&gt; &lt;data&gt; &lt;record model="ir.ui.view" id="hello_form_view"&gt; &lt;field name="name"&gt;hello.form&lt;/field&gt; &lt;field name="model"&gt;hello&lt;/field&gt; &lt;field name="type"&gt;form&lt;/field&gt; &lt;field name="arch" type="xml"&gt; &lt;form string="Hello Form"&gt; &lt;field name="name" select="1" /&gt; &lt;field name="note_ids" widget="many2many_list"/&gt; &lt;/form&gt; &lt;/field&gt; &lt;/record&gt; &lt;/data&gt; &lt;/openerp&gt; </code></pre> <p>There is no error in installing and the fields are also displayed and data is stored in the Database.</p> <p>My problem arises as inter-relationship between note_ids and tag_ids is not proper.</p> <p>Example:</p> <pre><code>If I have a notebook record as : title = sample tags = tag1, tag2 The tags are created in hello record as: tag1 record: name="tag1" Notebooks = "" tag2 record: name="tag2" Notebooks= "" </code></pre> <p>Why is the relationship not maintained?</p>
