I'm trying to upload a file using Rails, Mongoid and Carrierwave. When I click submit, the value of "image" in the POST request is {url : null}
. When I use logger to view the value of "image" from the create action in my controller, the value is "C:\\fakepath\\tree.png"
so I can't just save it directly using File.open to get the file since this is not the real path. This is the first time I'm writing a form with an uploader so I'm not really sure what I'm doing.
Here's my form for uploading the image:
<h1>New Post</h1>
<form id="new-post" name="post" enctype="multipart/form-data">
<div class="field">
<label for="name"> Name</label><br />
<input type="text" name="name" id="name" value="<%= name %>" >
</div>
<div class="field">
<label for="image"> Image</label><br />
<input type="file" name="image" id="image" value="<%= image %>" >
</div>
<div class="field">
<label for="content"> Content</label><br />
<textarea rows="4" cols="50" name="content" id="content" value="<%= content %>" ></textarea>
</div>
<div class="actions">
<input type="submit" value="Create Post" />
</div>
</form>
Here's what I added to support carrierwave:
Gemfile:
gem "carrierwave"
gem "carrierwave-mongoid", :require => 'carrierwave/mongoid'
PostModel:
attr_accessible :name, :content, :image
mount_uploader :image, ImageUploader
ImageUploader:
class ImageUploader < CarrierWave::Uploader::Base
storage :file
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
