ODOO

reports

 

we can let the user choose the language for report with out change his language as bellow

• define languages field as bellow 

report_language = fields.Many2one('res.lang','Report Language', required=True)

• define the external template in which we call the language that entered by the user as bellow 

<template id="report_main_temp">
      <t t-call="report.html_container">
        <t t-foreach="docs" t-as="doc">
          <t t-call="certifications.student_file_template" t-lang="doc.certification_language.code"/>
        </t>
      </t>
    </template>  

• the we will add internal template in which we will define report body for each language we installed in our system 

 EG : for English language 

<template id="report_file_template">
      <!-- <t t-foreach="docs" t-as="o" > -->
        <t t-set="doc" t-value="doc.with_context({'lang':doc.report_language.code})" />

<t t-if="line(data)[0]['c_language'].code == 'en_US'">

""" the report body in English language """

</t>

</t>

</template>
