How to pass parameters to a dashboards meta data (title and output-file)?

[brianmcdonald]

Description

I would like to produce multiple dashboards, each with custom text in the title and the output-file name, which are passed by the parameter option(or similar) when running quarto render eg `quarto render -P zone:"example_text"

While the Parameter option works well for parameters within the body of the analysis, it doesn't seem to work for the meta data. Similarly Variables, Meta and Env, allow for placing text in the metadata but not in a parameterized manner that allows multiple dashboards from multiple inputs.

Below is my document code. Any solutions or ideas are welcome.

---
title: Zone name - {{< meta params.zone >}}
author: ''
subtitle: Zonal Profile
title-block-banner: '#1B657C'

output-file: {{< meta params.zone >}}
lightbox: true
format:
  dashboard:
    logo: input/logo.svg
    include-in-header:
      text: <link rel="icon" type="image/x-icon" href="favicon.ico">
    orientation: columns
    theme:
      - input/Cluster.scss
---

# Page 1

### Column {width="65%"}

#### Row {.tabset}

##### Tab 1

test1
```{python}
#| tags: [parameters]
zone = "testZone"
```

A discussion on this is here

It seems that Profiles can achieve what I'm looking for.

There are multiple threads already discussing this extensively.

• How can I create multiple documents from one set of variables? #10234

And many more.

Thanks @mcanouil that second link was very useful

What worked best for me in the end was to use the -M flag, -o flag and -P flags all together when rendering the project.
-M to set the title, -o to set the output filename, and -P for parameters

I preferred passing them on the command line rather than generating many yml files

Glad you're found a way that suits you!
