| custom_templates:custom-pages-parameters | custom_templates | custom-pages-parameters | Path parameters for pages | You can define custom pages that match multiple paths by creating files with {variable} definitions in their filenames. For example, to capture any request to a URL matching /about/* , you would create a template in the following location: templates/pages/about/{slug}.html A hit to /about/news would render that template and pass in a variable called slug with a value of "news" . If you use this mechanism don't forget to return a 404 if the referenced content could not be found. You can do this using {{ raise_404() }} described below. Templates defined using custom page routes work particularly well with the sql() template function from datasette-template-sql or the graphql() template function from datasette-graphql . | ["Custom pages and templates", "Custom pages"] | [{"href": "https://github.com/simonw/datasette-template-sql", "label": "datasette-template-sql"}, {"href": "https://github.com/simonw/datasette-graphql#the-graphql-template-function", "label": "datasette-graphql"}] |
| custom_templates:custom-pages-headers | custom_templates | custom-pages-headers | Custom headers and status codes | Custom pages default to being served with a content-type of text/html; charset=utf-8 and a 200 status code. You can change these by calling a custom function from within your template. For example, to serve a custom page with a 418 I'm a teapot HTTP status code, create a file in pages/teapot.html containing the following: {{ custom_status(418) }} <html> <head><title>Teapot</title></head> <body> I'm a teapot </body> </html> To serve a custom HTTP header, add a custom_header(name, value) function call. For example: {{ custom_status(418) }} {{ custom_header("x-teapot", "I am") }} <html> <head><title>Teapot</title></head> <body> I'm a teapot </body> </html> You can verify this is working using curl like this: $ curl -I 'http://127.0.0.1:8001/teapot' HTTP/1.1 418 date: Sun, 26 Apr 2020 18:38:30 GMT server: uvicorn x-teapot: I am content-type: text/html; charset=utf-8 | ["Custom pages and templates", "Custom pages"] | [] |
| custom_templates:custom-pages-404 | custom_templates | custom-pages-404 | Returning 404s | To indicate that content could not be found and display the default 404 page you can use the raise_404(message) function: {% if not rows %} {{ raise_404("Content not found") }} {% endif %} If you call raise_404() the other content in your template will be ignored. | ["Custom pages and templates", "Custom pages"] | [] |
| custom_templates:custom-pages-redirects | custom_templates | custom-pages-redirects | Custom redirects | You can use the custom_redirect(location) function to redirect users to another page, for example in a file called pages/datasette.html : {{ custom_redirect("https://github.com/simonw/datasette") }} Now requests to http://localhost:8001/datasette will result in a redirect. These redirects are served with a 302 Found status code by default. You can send a 301 Moved Permanently code by passing 301 as the second argument to the function: {{ custom_redirect("https://github.com/simonw/datasette", 301) }} | ["Custom pages and templates", "Custom pages"] | [] |
