make_listΒΆ

Forces the value to a list.

This is especially useful for loops using the {% for %} tag.

For example:

{{ value|make_list }}

When value is the tuple {"a","b"} then the output is the list ["a","b"].

When the input is a model, this filter forces the model to call its m_to_list/2 function, which is used to iterate over an entire model, e.g.:

{% print m.req|make_list %}

This will show something like:

[{version,{1,1}},
 {peer,"127.0.0.1"},

Instead of printing just {m, req, undefined} when the filter was not applied.
