|
Because Lektor renders out static pages the question comes up what happens if a
|
|
|
|
page cannot be found. This is typically achieved by a special page that a
|
|
|
|
server will then use as a stand-in for a page that otherwise cannot be found.
|
|
|
|
|
|
|
|
In Lektor as a convention this page should be called `404.html`. While in
|
|
|
|
reality the name of this page largely depends on how you deploy your pages we
|
|
|
|
are sticking with the generally accepted location of calling it `404.html`.
|
|
|
|
This will work on GitHub Pages and some other environments where this cannot
|
|
|
|
be otherwise configured and most web servers can be configured to use this file
|
|
|
|
for URLs that are not found.
|
|
|
|
|
|
|
|
! In versions of Lektor before 2.0 custom 404 pages will not be honored by the
|
|
|
|
development server. To test those you will need to explicitly navigate to
|
|
|
|
`/404.html`.
|
|
|
|
|
|
|
|
## URLs on 404 Pages
|
|
|
|
|
|
|
|
If you are using 404 pages then these pages can appear at any URL. This means
|
|
|
|
that relative URLs *will not work*. If you want to use custom error pages you
|
|
|
|
will have to set the `url_style` to `absolute` as otherwise URLs on an error
|
|
|
|
page will not work. Just add this to your project file:
|
|
|
|
|
|
|
|
```ini
|
|
|
|
[project]
|
|
|
|
url_style = absolute
|
|
|
|
```
|
|
|
|
|
|
|
|
For more information about this you can read the [Project File Documentation
|
|
|
|
:ref](../../project/file/).

## Creating an Error Page
|
|
|

|
|
|
You can easily add a 404 page by creating a `404.html/contents.lr`
|
2015-12-29 12:27:50 +01:00
|
|
|
file. If you do not care much about the contents and structure of the file
|
|
|
|
you can just point it to an empty model (`none`) and manually select a
|
|
|
|
`404.html` template like this:
|
|
|
|
|
|
|
|
```
|
|
|
|
_model: none
|
|
|
|
----
|
|
|
|
_template: 404.html
|
|
|
|
```
|
|
|
|
|
|
|
|
Then just create a `404.html` template with the intended contents.

## Server Configuration
|
|
|
|
|
|
|
|
If you are deploying such pages to your own servers you will need to ensure
|
|
|
|
that the error pages are activated. Depending on the server used this will
|
|
|
|
work slightly differently.
|
|
|
|
|
|
|
|
### Apache
|
|
|
|
|
|
|
|
Making custom error pages work is easiest with Apache. If `.htaccess` files
|
|
|
|
are enabled you can just put a file with that name into your `assets` folder
|
|
|
|
and add the following line to it:
|
|
|
|
|
|
|
|
```apache
|
|
|
|
ErrorDocument 404 /404.html
|
|
|
|
```
|
|
|
|
|
|
|
|
Alternatively you can add the above line into a `VirtualHost` or `Directory`
|
|
|
|
section in your main config file.
|
|
|
|
|
|
|
|
### nginx
|
|
|
|
|
|
|
|
For nginx you need to enable the error document in your main config file. Just
|
|
|
|
add it to your `server` section:
|
|
|
|
|
|
|
|
```nginx
|
|
|
|
error_page 404 /404.html;
|
|
|
|
```
|
|
|
|
|
|
|
|
### lighttpd
|
|
|
|
|
|
|
|
If you are using lighttpd you can configure an error page for 404 this way:
|
|
|
|
|
|
|
|
```ini
|
|
|
|
server.error-handler-404 = "/404.html"
|
|
|
|
```
