controller

问题 I have some common components that are always present in every page served by a given Controller class. At the beginning of each @RequestMapping method I populate the model with these common components. Is there a way to define a method be called prior to each of the controller methods so that I can get all of this copy/paste into one place? 回答1: Just annotate a method with @ModelAttribute The below would add a Foo instance to the model under the name "foo" @ModelAttribute("foo") public Foo

问题 My question says it all. I already did a controller to search all records from specific model. Now I want to search just one record (by its id) from the same model. My controller for all records is this: @http.route('/get_sales', type='json', auth='user') def get_sales(self): sales_rec = request.env['sale.order'].search([]) sales = [] for rec in sales_rec: vals = { 'id': rec.id, 'name': rec.name, 'partner_id': rec.partner_id, } sales.append(vals) data = {'status': 200, 'response': sales,

问题 I have a Rails 4 application where I need to force the controller to send a js response to all requests, html or js. For some reason, the browser is displaying the response as text instead of executing the code when the controller receives an html request (for example, when the user makes a request by typing in the url). Controller: def action render :template => 'sessions/home.js.erb', :content_type => "text/javascript" end sessions/home.js.erb: $("#button").on("click", function(){ alert(

问题 I've been looking for mechanism to update the model of a Route, and has the Component (called from within the template associated with that route) reacts to that event, and re-render itself. So I have the index template like this (I pass in the model of the IndexController, which to my understanding is just a proxy to IndexRoute -- I don't have IndexController defined, by the way): <script type="text/x-handlebars" id="index"> Below is the bar-chart component <br/> {{bar-chart model=model}} <
