how to add a user defined header in a rml report in openerp?

Question

How can I add a new header/footer for a report(for example picking list report in delivery order) other than the header/ footer defined in the company?

Answer 1

In report tag put header='False', eg.

<report header='False' auto="False" id="report_product_history" 
model="product.product" name="stock.product.history"
 string="Stock Level Forecast"/>

it will not print the default header define in the company. then in rml file find <pageTemplate> tag, and replace it with your rml code. eg.

 <template pageSize="(595.0,842.0)" title="Test" 
        author="Atul Makwana" allowSplitting="20">
        <pageTemplate id="first">
         ***Your rml header & footer***
        </pageTemplate>
 </template>

This way you can put new header and footer.

Answer 2

One way to remove the header is what Atul suggested, declare it in the report tag.

<report 
    header="False"
    auto="False" 
    id="report_product_history" 
    model="product.product" 
    name="stock.product.history"
    string="Stock Level Forecast"/>

In some situations there is no report tag. For example, a report might only be generated by a wizard. In that case, you can declare it as a parameter when you register the parser. See the mrp_operations module's barcode report for an example.

class code_barcode(report_sxw.rml_parse):
    def __init__(self, cr, uid, name, context):
        super(code_barcode, self).__init__(cr, uid, name, context=context)
        self.localcontext.update({
            'time': time,
        })

report_sxw.report_sxw('report.mrp.code.barcode', 
                      'mrp_operations.operation.code', 
                      'addons/mrp_operations/report/mrp_code_barcode.rml',
                      parser=code_barcode,
                      header=False)

You can also specify a specific header using that parameter. It defaults to 'external', but it can be 'internal' or 'internal landscape' to use one of the other headers from the company configuration.
