I have bank statement form view like this :

<record id="view_account_bank_statement_form" model="ir.ui.view">
    <field name="name">account.bank.statement.formfield>
    <field name="model">account.bank.statementfield>
    <field name="arch" type="xml">
        <form string="Account Bank Statement">
        <header>
        header>
        <sheet>
            <div class="oe_title">
                <h1>
                    <field name="name"/>
                h1>
            div>
            <group>
                <field name="date"/>
                <field name="journal_id" context = "{'parent_journal_id':journal_id}"/>
                <field name="balance_start" context = "{'balance_start':balance_start}"/>
                <field name="balance_end"/>
                <field name="balance_end_real"/>
            group>
            <notebook>
                <page string="Statement Line" name="line_ids">
                    <field name="line_ids">
                        <tree string="Bank Statement Lines" editable="bottom" context="{'o2m_active_model': 'account.bank.statement',
                        'journal_id': journal_id}">
                            <field name="date"/>
                            <field name="state"/>
                            <field name="payment_ref"/>

                            <field name="amount"/>
                            <field name="suitable_journal_ids"/>
                            <field name="currency_id"/>
                            <field name="journal_id"/>
                        tree>
                    field>
                page>
            notebook>
        sheet>
        form>
    field>record>



But when I tried to get the context with this code:
context = self.env.context
parent_journal_id = context.get('parent_journal_id',False)
journal_id = context.get('journal_id',False)
Both of them return none, what did I do wrong? I had experience with openerp7, they pass context on the function. But Im not familiar with odoo 16, can someone help me please?

When passing context to fields, it primarily affects views and not Python methods. If you need to pass static context, it's better to pass it through actions. However, without a clear understanding of your specific use case, I am unable to provide further guidance. Thank you.

Here's an example of how you can modify the existing method to access the parent_journal_id and journal_id from the context:

def my_method(self):
    context = dict(self.env.context or {})
    parent_journal_id = context.get('parent_journal_id')
    journal_id = context.get('journal_id')

You can modify the code inside the method to use the values of parent_journal_id and journal_id as needed.

It was always returned none eventhough Im already have attribute "context" at xml, did I do something wrong?

Bhavin Patel

The context attribute should be defined XML view. at the field level, like this:

If you have defined the context attribute correctly, then the value of my_variable should be available in the context dictionary when you call self.env.context.

Check that you are passing the context to the method correctly. If you are calling the method from another model or controller, you need to make sure that the context is being passed along with the method call. For example:

self.env['my.model'].my_method(context={'my_variable': 'my_value'})

This will pass the my_variable value in the context dictionary to the my_method method.

If you are still not able to retrieve the values from the context dictionary, try printing out the context dictionary using print(self.env.context) at the beginning of the my_method method to check whether the context is being passed correctly.
