    <p>I am trying to create an ActiveRecord object via a JSON request. However the controller fails to set the variables passed in the parameters in the newly created object. As an example, a person object has two fields: firstname and lastname.</p> <p>The JSON generated by the JSON.stringify function of the JSON.org library produces:</p> <pre><code>{"firstname" : "Joe" , "lastname" : "Bloggs"} </code></pre> <p>However the controller expects the JSON to be in the form:</p> <pre><code>{ "Person" : {"firstname" : "Joe" , "lastname" : "Bloggs"} } </code></pre> <p>I am aware that in the normal course of events (for HTTP requests) the parameters for the request are nested under the class name of the model being created. </p> <p>The create action in the controller is:</p> <pre><code>def create @person = Person.new(params[:person]) respond_to do |format| if @person.save flash[:notice] = 'Person was successfully created.' format.html { redirect_to(@person) } format.xml { render :xml =&gt; @person, :status =&gt; :created, :location =&gt; @person } format.json { render :json =&gt; @person, :status =&gt; :created, :location =&gt; @person } else format.html { render :action =&gt; "new" } format.xml { render :xml =&gt; @person.errors, :status =&gt; :unprocessable_entity } format.json { render :json =&gt; @person.errors, :status =&gt; :unprocessable_entity } end end end </code></pre> <p>What would be the neatest way for the controller to process the JSON requests as generated? Or alternatively how do you generate "correct" JSON from Javascript objects for passing to your controllers?</p> <p>TIA, Adam</p>

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.
