I would like to extend the `l10n_in` localization in my custom module `test_module` by adding additional accounts to the Chart of Accounts `l10n_in.indian_chart_template_standard`.
Defined `account.account.template` XML data containing entries like:
<record model="account.account.template" id="p10100">
<field name="name">Test Account Receivable</field>
<field name="code">10100</field>
<field name="user_type_id" ref="account.data_account_type_current_assets"/>
<field name="reconcile" eval="False"/>
<field name="chart_template_id" ref="l10n_in.indian_chart_template_standard"/>
</record>
I have also defined an XML to load the templates for companies:
<data noupdate="0">
<function model="account.chart.template" name="try_loading_for_current_company">
<value eval="[ref('l10n_in.indian_chart_template_standard')]"/>
</function>
</data>
But installing `test_module` on a new database results in following error (because the journals are already created by `l10n_in` module and it tries to load again?)
odoo.tools.convert.ParseError: "duplicate key value violates unique constraint "account_journal_code_company_uniq" DETAIL: Key (code, name, company_id)=(INV, Tax Invoices, 1) already exists. " while parsing /opt/odoo/addons/test_module/data/account_chart_template_data.xml:4, near <function model="account.chart.template" name="try_loading_fpos_for_current_company"> <value eval="[ref('l10n_in.indian_chart_template_standard')]"/> </function>
What is the best practice to handle such cases properly in code?
