file_field_tag(name, options = {})
Instance Public methods
Creates a file upload field. If you are using file uploads then you will also need to set the multipart option for the form tag:
<%= form_tag '/upload', multipart: true do %> <label for="file">File to Upload</label> <%= file_field_tag "file" %> <%= submit_tag %> <% end %>
The specified URL will then be passed a File object containing the selected file, or if the field was left blank, a StringIO object.
Options
-
Creates standard HTML attributes for the tag.
-
:disabled- If set to true, the user will not be able to use this input. -
:multiple- If set to true, *in most updated browsers* the user will be allowed to select multiple files. -
:accept- If set to one or multiple mime-types, the user will be suggested a filter when choosing a file. You still need to set up model validations.
