    text
    copied!<p>I have a prescription model in my Rails 3 application. I am trying to work out the best method of allowing records to be duplicated, but allowing the user to "review" the duplicate before it's saved.</p> <p>I have read a number of questions/answers on SO (such as <a href="https://stackoverflow.com/questions/2070250/clone-a-k-a-duplicate-a-record">this</a> one) which explain how to duplicate/clone the record and then save it - but none which explain how to show the form before save.</p> <p>Reading the Rails API is appears the <a href="http://edgeapi.rubyonrails.org/classes/ActiveResource/Base.html#method-i-clone" rel="nofollow noreferrer">clone</a> method is available.</p> <p>Reading <a href="https://stackoverflow.com/questions/60033/what-is-the-easiest-way-to-duplicate-an-activerecord-record?lq=1">other questions</a> and answers shows that is can be done but there is no example code apart from:</p> <pre><code>new_record = old_record.dup </code></pre> <p>The controller code I am currently working with is as follows (the model doesn't have any relationships):</p> <pre><code> # POST /prescriptions # POST /prescriptions.json def create @prescription = Prescription.new(params[:prescription]) @prescription.localip = request.env['REMOTE_ADDR'] @prescription.employee = @prescription.employee.upcase respond_to do |format| if @prescription.save format.html { redirect_to @prescription, notice: 'Prescription was successfully created.' } format.json { render json: @prescription, status: :created, location: @prescription } else format.html { render action: "new" } format.json { render json: @prescription.errors, status: :unprocessable_entity } end end end </code></pre> <p>I am going to be linking to this clone action from the view with:</p> <pre><code>&lt;%= link_to "Create another like this?", clone_prescription_url(@prescription), :method =&gt; :put %&gt; </code></pre> <p>Is it as simple as adding an action to my controller like this?</p> <pre><code>def clone @prescription = Prescription.find(params[:id]) @prescription.dup @prescription.save end </code></pre> <p>Apologies if the above code is completely wrong, I'm trying to get my head around it! I've seen <a href="https://stackoverflow.com/questions/8555488/rails-duplicate-record-not-rendering-new?rq=1">someone</a> do exactly what I'm trying to achieve with the cloning - but not with the editing before save.</p> <p>The user that's duplicating won't have permission to edit a record once saved. It's purely for the intial data entry.</p>
