Hello there,

I'm searching the way to directly attrib a variable value to an attribute of a tag :

    <template id="website_lapagept.facebook_open_graph_tags_iv">

        <t t-set="variable" t-value="FFRGRGRGFGFGFBVFVFGGFGFGFVF" />

        <meta property="og:title" content="" />

        <meta property="og:type" content=variable />  (IT DOESN'T WORK)

    </template>

Could you help me please?

UPDATE #1

ref : https://www.odoo.com/fr_FR/forum/help-1/question/append-value-to-attribute-in-qweb-template-76953

If I inherit the above template, I can change the « content » attribute value. But it is not what I want. Can we do this without inheritance and without xpath?

    <template id="website_lapagept.facebook_open_graph_title_iv" inherit_id="website_lapagept.facebook_open_graph_tags_iv" name="Facebook open graph description - IV">

            <xpath expr='//meta[@property="og:title"]' position="attributes">

                    <attribute name="content">Intime &amp; vilain</attribute>

            </xpath>

    </template>

UPDATE #2

This new way doesn't work too :

    <template id="website_lapagept.facebook_open_graph_tags_iv">

        <t t-set="variable" t-value="FFRGRGRGFGFGFBVFVFGGFGFGFVF" />

        <meta t-att="{'property':'og:type', 'content':variable}" />

</template>

UPDATE #3

This new way doesn't work too : 

    <template id="website_lapagept.facebook_open_graph_tags_iv">

        <t t-set="variable" t-value="FFRGRGRGFGFGFBVFVFGGFGFGFVF" />  

        <meta property="og:type" t-att-content="variable" />

    </template>
