BTW, if I wanted to say, include the actual SVG code instead of using an <img> tag, what would be the correct way to go about it? Sort of like in PHP where <?php include "/images/sample.svg"; ?> ?

I don’t know if there is any idiomatic approach to working with SVG in phoenix, but if I knew that the image is very unlikely to change I’d do the following:

I’d make a function in my view with the SVG like

defmodule MyApp.SomeView do
  use Web, :view

  sample_svg = File.read!("priv/static/images/sample.svg")

  @spec sample_svg :: binary
  def sample_svg do
    unquote(sample_svg)
  end
end

This would read the svg at compile time and “persist” it in a function. This way the function just outputs the svg contents (as they were at compile time) any time it is called.

In my EEx templates I’d be able to do the following then:

...
<%= MyApp.SomeView.sample_svg() %>
...

Another (probably easier) approach would be to turn the svg into an EEx template.

I’d create a new _sample.svg.eex (or sample_svg.html.eex if the previous one doesn’t work) with the contents of priv/static/images/sample.svg (that one could be deleted then, since it’s been replaced by the eex template) and call <%= render "_sample.svg" %> from within my other EEx templates.

FYI: Phoenix Inline SVG

Can you post that error?

Can you also maybe post the contents of _static-section.html.eex?
