I figured out a work around and I figured I'd post it here in case anyone
can benefit.
You can set up Paperclip to load an image using a url instead of selecting
a file from your local PC. I had this set up, but haven't used it in a
while. (I had removed that form field from the new form, so that it
couldn't be accessed) You can find tutorials online to set that up. To make
my app work, I added the field back to the form:
<div class="form-group">
<%= f.input :image_remote_url, label: "or enter a URL" %>
</div>
And my controller now is:
def copy
@source = Pin.find(params[:id])
@image = @source.image.url
@pin = Pin.new(artist: @source.artist, album: @source.album, year:
@source.year, image_remote_url: @image)
render 'new'
end
And I had to add .to_s to the image_remote_url method in my model:
def image_remote_url=(url_value)
self.image = URI.parse(url_value).to_s unless url_value.blank?
super
end
Now when a user clicks a button on a record in my app, which is coded:
<%= link_to "copy", copy_pin_path(params[:id]) %>
It takes them to the new form, with the artist, album, year, and the url of
the image already filled in.
