# `MishkaCmsCore.Runtime.Resources.Validations.PageUploads`
[🔗](https://github.com/mishka-group/mishka_cms_core/blob/v0.0.1/lib/mishka_cms_core/runtime/resources/__validations/page_uploads.ex#L5)

Refuses a page whose `uploads` declares a file field no visitor could use.

A published page is a form an anonymous visitor posts to, so every upload names the types it
takes, checked at the action boundary every writer passes — the builder, the page form, the JSON
API and a seed alike:

  * `accept` is required: `image/*, .pdf` says what is wanted, and nothing says "anything";
  * every type in it is one `MishkaCmsCore.Runtime.PageUpload.allowed_types/0` lists. HTML, SVG, XML
    and script files are never among them, because the site serves what a visitor uploads from its
    own origin.

A row with no name is left to the compiler, which drops it: a half-filled row is one keystroke
away from a finished one.
