How to get report_name in Qweb header in Odoo 10?

I need to show a string in the header of several reports which must change depending on the report which is being printed.

By now, I had done this:

<template id="external_layout_header" inherit_id="report.external_layout_header">
    ...
    <t t-if="o._table=='sale_order'">
        ... Print here what I need to show in sale order reports ...
    </t>
    ...
</template>

It worked well for me, but now, the string does not depend on the model/table, but on the printed report.

I have a model which has two different reports to print. If one is printed, I have to show 'X' in the header, if the other one is printed, I have to show 'Y' in the header. There is no difference between them, I mean, there is no attribute in the model which allows me identify them.

For example, in a previous case, despite having the same model, I was able to show the correct string due to the state field value:

<template id="external_layout_header" inherit_id="report.external_layout_header">
    ...
    <t t-if="o._table=='sale_order'">
        <t t-if="o.state=='draft'">
            ... Print Sale Quotation ...
        </t>
        <t t-if="o.state!='draft'">
            ... Print Sale Order ...
        </t>
    </t>
    ...
</template>

But in this case there is no field which helps me. Only the report name, so I need to get it from the header.

Does anyone know how to achieve this?

I tried this and it worked hope you get the idea. First there is some fact that I know (but not for sure) that made me came with this logic.

  1. There is no direct way to set a attribute on docs or o(RecordSet passed to report) on Qweb.
  2. We have access to context o.env.context.
  3. when you call a template inside another the last one have access to the the scope of the first template.

Instead of adding attribute why we don't just add a key to the magic attribute context using o.with_context using the power of t-set we can add an extra key but we need to make sure we do this before we call <t t-call="report.external_layout"> in the report template so the external_layout can find that extra key on the context ^^

 <!-- add extra key to context -->
 <!-- you can set it one time on docs it's better -->
 <t t-set="o" t-value="o.with_context(report_name='hello_report')"/> 
 <t t-call="report.external_layout">

Now because context is frozendict instance or something like it (I'm not sure), we can use get with default value to check if that special key is passed on the context.

<template id="external_layout_header" inherit_id="report.external_layout_header">
        ...
        <t t-if="o.env.context.get('report_name', False) == 'hello_report'">
                   <!-- show what you want to show  for this report -->

Or you can make it even better by making this behavior generale by just passing the value itself in the context this will minimize number of if statements on you external_layout .

<template id="external_layout_header" inherit_id="report.external_layout_header">
        ...
        <t t-if="o.env.context.get('extra_value', False)">
              <p t-esc="o.env.context.get('extra_value')"></p>

So for any report that you need it to have this behavior. if it's existing one inherit the template and make sure that you add the key before calling external_layout using x-path.

Edits:

an example of the result this is in odoo 8.0 I didn't use inherit I directly updated the remplates.

sale.order template

<template id="report_saleorder_document">
    <t t-set="o" t-value="o.with_context(extra_info='show this on header')"/>
    <t t-call="report.external_layout">

external layout on report 

 <template id="external_layout_header">
        <div class="header">
            <div class="row">
                <t t-if=" 'extra_info' in o.env.context" >
                    <p t-esc="o.env.context.get('extra_info')"></p>
                </t>
                <div class="col-xs-3">
                    <img t-if="company.logo" t-att-src="'data:image/png;base64,%s' % company.logo" style="max-height: 45px;"/>
                </div>
                <div class="col-xs-9 text-right" style="margin-top:20px;" t-field="company.rml_header1"/>
            </div>
            ....
            .....
            ...

result is this

final result
