Updating from 0.12

[BBaoVanC]

I've been putting this off because of the amount of breaking changes and effort, but finally doing it now. Full code in bobashare. A few issues/questions:

0.13 ✔️

Upgrading from 0.12 to 0.13, there was a breaking change since the MIME_TYPE associated const was removed. I was using this to set the content-type header in my responses. I fixed it by just hardcoding the return to be HTML since presumably askama will always render HTML output. Does this seem sound?

0.14 ❓

Honestly I am lost. I switched the version from 0.13 to 0.14 and I get a bunch of errors like this, for every single template:

error[E0061]: this function takes 1 argument but 2 arguments were supplied
  --> bobashare-web/src/views/about.rs:11:10
   |
11 | #[derive(Template)]
   |          ^^^^^^^^ unexpected argument #2 of type `&dyn views::_::askama::Values`

  --> bobashare-web/src/views/filters.rs:39:8
   |

   |        ^^^^^^^^^
   = note: this error originates in the derive macro `Template` (in Nightly builds, run with -Z macro-backtrace for more info)

I can't really understand enough to tell if this lines up with a specific change in the changelog. Any idea what's going on?

0.15

Need to get 0.14 upgrade working before I can do 0.15. Hoping nothing big breaks.

Just tried applying the fixes for 0.15. It looks like there's new warnings, about how I call a block with the same name multiple times in my base template.

⚠️ bobashare-web/templates/base.html.jinja:16:46: block `title` was already called at `bobashare-web/templates/base.html.jinja:7:18` so the previous one will be ignored
⚠️ bobashare-web/templates/base.html.jinja:17:47: block `title` was already called at `bobashare-web/templates/base.html.jinja:16:46` so the previous one will be ignored

I did this because I want to reuse the value of the title block multiple times between the <title> and in the meta tags:

<title>{% block title %}{% endblock %} - bobashare</title>
                                                                                                                                      
<!-- snip -->
                                                                                                                                      
{% block preview_metadata %}
<meta property="og:title" content="{% block title %}{% endblock %}">
<meta name="twitter:title" content="{% block title %}{% endblock %}">
{% endblock %}

I originally used a block because all I need to do, from the perspective of the base template, is override the title in the more specific child templates. Is this a false warning, or should I rewrite this to work differently?
