<p>I'm trying to create a custom partial for a has_many relationship and running into some issues.</p> <p>My models</p> <pre><code>Message has_many :formats Format belongs_to :message validates_inclusion_of :format_type, :in => FORMAT_TYPES.keys </code></pre> <p>I have a constant "FORMAT_TYPES" (wmv, flv, etc...) so that each "Format" record has a message_id and a format_type string that is in the allowed list.</p> <p>I'm trying to create a custom partial for rails_admin that allows the admin to use checkboxes to select which formats they want. Here's what I've got:</p> <pre><code>- for format in FORMAT_TYPES.keys %div = check_box_tag "message[formats][]", format = format </code></pre> <p>Which outputs this:</p> <pre><code><fieldset> <legend>Formats</legend> <div> <input id="message_formats_" name="message[formats][]" type="checkbox" value="640x360_8"> 640x360_8 </div> <div> <input id="message_formats_" name="message[formats][]" type="checkbox" value="480x272_8"> 480x272_8 </div> ... </fieldset> </code></pre> <p>When I select a few formats and submit, I get this error:</p> <pre><code>ActiveRecord::AssociationTypeMismatch in RailsAdmin::MainController#create Format(#2196273220) expected, got String(#2151941320) </code></pre> <p>This sounds like it's expecting an existing Format id. Which makes me think I have to create a has_many_through and get rid of my constant. (trying to avoid that) </p> <p>Trying to figure out how to properly format my partial to allow the creation of these new Format records. Any ideas?</p> <p>Much thanks in advance!</p>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
