    <p>I would like to add a video file to an Episode model using Paperclip in a Rails 4.0.0 app. However, I get an error "no implicit conversion of Symbol into Hash" when I call episode_params in my create action (second line):</p> <pre><code>def create @episode = Episode.new(episode_params) respond_to do |format| if @episode.save format.html { redirect_to @episode, notice: 'Episode was successfully created.' } format.json { render action: 'show', status: :created, location: @episode } else format.html { render action: 'new' } format.json { render json: @episode.errors, status: :unprocessable_entity } end end </code></pre> <p>end</p> <p>My episode_params method:</p> <pre><code>def episode_params params.require(:episode).permit(:name, :number, :description, :tag_list, :video =&gt; [:tempfile, :original_filename, :content_type, :headers]) end </code></pre> <p>And the params hash:</p> <pre><code>{"utf8"=&gt;"✓", "authenticity_token"=&gt;"VbOJvzWjlXMHOYpYMkwXUfdUxm9OcQx3LTMIJzk5eJQ=", "episode"=&gt;{"name"=&gt;"Test Episode 2", "number"=&gt;"2", "description"=&gt;"Testing Paperclip with video files", "tag_list"=&gt;"test, file, video", "video"=&gt;#&lt;ActionDispatch::Http::UploadedFile:0x007fec361a80e0 @tempfile=#&lt;Tempfile:/var/folders/yt/prn3v4gx3_bcrq8kr6wlfjjw0000gn/T/RackMultipart20130817-15917-1gu47ht&gt;, @original_filename="file.mov", @content_type="video/quicktime", @headers="Content-Disposition: form-data; name=\"episode[video]\"; filename=\"file.mov\"\r\nContent-Type: video/quicktime\r\n"&gt;}, "commit"=&gt;"Create Episode", "action"=&gt;"create", "controller"=&gt;"episodes"} </code></pre> <p>I've also tried with just :video instead of :video => [ etc ] with no luck. Any ideas would be greatly appreciated.</p> <p>Full backtrace:</p> <pre><code>TypeError - no implicit conversion of Symbol into Hash: paperclip (3.5.1) lib/paperclip/attachment.rb:72:in `initialize'

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
