Use on non-image assets

[rlmattax]

I'm hoping to find a way to attach non-image objects to a model. The example at hand is an html file.

I'm also trying to do the attachment within a model instead of using the uploader.

Do you have any suggestions for doing these things?

This is how I'm using it

--------------

publisher.rb

assetable :ad_block # the html chunk

Then just for the sake of testing things, I opened the console, and attempted (based largely on my experience with carrier wave):

publisher.ad_block = File.open("ad_block.html")

ang get this error:
NoMethodError: undefined method `id' for #File:ad_block.html

Any suggestions?

Hey bob,
I dont think we've tried html before.
It looks like your carrierwave mount is setup a bit differently than us.

the error
NoMethodError: undefined method 'id' for #File:ad_block.html

makes sense, because i believe something is looking for a model, with an id rather than a IOObject which is what File:ad_block.html in your example is.

If you look at
https://github.com/kohactive/assetable/tree/master/app/models
you should see the subset of model types supported, i would suggest trying out Document.

Assetable expects the attachment should be a model reference so you would want to do something like this.
publisher.ad_block = Document.create(filename: File.open("ad_block.html")
This will do 2 things, create an Asset object with a type of 'Document' using STI (Single Table Inheritence) and assign it to the ad_block relationship on publisher.

I believe in the next release we will probably swap out root level models included with namespaced models.

Assetable::Document to prevent collision in integrating apps where they already have a Document model.

You can then get the url to the attachment with

publisher.ad_block.filename.url

Hey @rlmattax one other thing that you'll need to change is the acceptable document formats. Check out the javascript file https://github.com/kohactive/assetable/blob/master/app/assets/javascripts/assetable/assetable_uploader.js.coffee#L74-L83 and you'll see that it only accepts certain types of files. I think this was an oversight and needs to be addressed.

Thanks guys. Very helpful. I'll try it out again and see if those suggestions helped.
