<%= link_to 'Comment', new_comment_path(commentable_type: 'post', commentable_id: commentable.id) %>

Since the form never rendered I'm not sure if I should include it here

Since I asked specifically for the form, that's what I need to see. The critical part will be the first line: <%= form_for ...

The link you posted here is just to get the form to display, but the error you asked about initially comes from the way that the form is constructed -- specifically just how the parameters are set up in the form request that it will submit.

Aha. I see what the problem could be. Your new method is trying to load a set of params, which is not the way this is usually done. Traditionally, the #new method is a GET request, which loads a generic form built around an empty new object. Since you are trying to set up the relationship with the commentable polymorphic object, maybe you should use a nested route to send that to the controller, or have a separate strong parameters accessor just for this form. You're sending the parameters as bare querystring options in the link helper, not nesting them into the comment object, which is why your accessor is failing you. If you changed the link to be

    new_comment_path( 'comment[commentable_type]': 'post', 'comment[commentable_id]: commendable.id)

...then your existing accessor will work, but that's a lot of typing when you could probably do this a lot easier with nested routes.

Aha. I see what the problem could be. Your new method is trying to load a set of params, which is not the way this is usually done. Traditionally, the #new method is a GET request, which loads a generic form built around an empty new object. Since you are trying to set up the relationship with the commentable polymorphic object, maybe you should use a nested route to send that to the controller, or have a separate strong parameters accessor just for this form. You're sending the parameters as bare querystring options in the link helper, not nesting them into the comment object, which is why your accessor is failing you. If you changed the link to be

    new_comment_path( 'comment[commentable_type]': 'post', 'comment[commentable_id]: <a href="http://commendable.id" target="_blank" rel="nofollow" onmousedown="this.href=&#39;http://www.google.com/url?q\x3dhttp%3A%2F%2Fcommendable.id\x26sa\x3dD\x26sntz\x3d1\x26usg\x3dAFQjCNHhwKdHC6buX64UiVu-9HKdjQDchw&#39;;return true;" onclick="this.href=&#39;http://www.google.com/url?q\x3dhttp%3A%2F%2Fcommendable.id\x26sa\x3dD\x26sntz\x3d1\x26usg\x3dAFQjCNHhwKdHC6buX64UiVu-9HKdjQDchw&#39;;return true;">commendable.id)

...then your existing accessor will work, but that's a lot of typing when you could probably do this a lot easier with nested routes.

The commentable had better exist at this point, otherwise, what are you putting in the type and ID attributes? This is a polymorphic relationship, commentable is meant to stand in for whatever -- Article, Image, BlogPost -- whatever you want to comment on. For the link you posted in the second message to this thread to work at all, you must already have persisted that *whatever* object, and that is what the commentable will be in this context.

Traditionally, the #new method is a GET request, which loads a generic form built around an empty new object. Since you are trying to set up the relationship with the commentable polymorphic object, maybe you should use a nested route to send that to the controller, or have a separate strong parameters accessor just for this form. You're sending the parameters as bare querystring options in the link helper, not nesting them into the comment object, which is why your accessor is failing you. If you changed the link to be

> The commentable had better exist at this point, otherwise, what are you putting in the type and ID attributes? This is a polymorphic relationship, commentable is meant to stand in for whatever -- Article, Image, BlogPost -- whatever you want to comment on. For the link you posted in the second message to this thread to work at all, you must already have persisted that *whatever* object, and that is what the commentable will be in this context.
