Rails: How to download a previously uploaded document?
I don't use Carrierwave but I guess it's similar to Paperclip.
Therefore you should be able to use something like this
link_to 'Download file', user.file.urlThis is assuming you have a user instantiated object from a Model with a 'file' carrierwave attribute. Replace this with your attribute name.
You can use the send_file method for this. Which could look like:
class MyController def download_file @model = MyModel.find(params[:id]) send_file(@model.file.path, :filename => @model.file.name, :type => @model.file.content_type, :disposition => 'attachment', :url_based_filename => true) endendCheck the apidock link for more examples.
Or you can put anchor tag:
in your controller:
@doc = "query to get the document name from your database"@docpath = request.base_url+"/uploads/"+@docin your view:
<a href="@docpath" download>Download File</a>.
