Im building my first site in Expression Engine, I was wondering how to use custom controllers in EE, like I would in Codeigniter, or what is the EE equivalent? Controllers are the heart of your application, as they determine how HTTP requests should be handled. As you're probably well-aware, a CodeIgniter Controller is simply a class file that is named in a way that can be associated with a URI. <?php class Blog extends CI_Controller { public function index() { echo 'Hello World!'; } } ?> The ExpressionEngine equivalent are template groups and templates , and are managed from within the

How to update two entities/model elements from one jsp in Spring MVC?

由 自作多情 提交于 2019-12-06 03:03:32
My requirement is to do a CREATE operation by providing the user with a form in a JSP with input fields from two entities (e.g. UserDetails and EmploymentDetails ) What is the most effective way to update two forms in a single jsp using a single submit? One approach I know of is to combine the two entities into a single wrapper-class and then send that object as Model. Is that the only solution? Kindly guide. It's a common practice to put any number of objects in a wrapper class and use this one to submit data with a single form. Additionally, you can use JSR-303 validation in any of objects:

问题 OK so I have a User which has_one Template and I want a page which is basically just an edit view of the Template . I have: class TemplatesController < ApplicationController def edit @template = current_user.template end def update @template = current_user.template if @template.update_attributes(params[:template]) flash[:notice] = "Template was successfully updated" end render :edit end end Now the 'problem' is when I call render :edit I actually end up on /template.1 instead of /template

问题 I have a view, header.php, that gets loaded in various controller methods. It contains my opening html tag, a base tag for my relative links, and some meta tags that I call in every page of my application.

How to load a scene in a storyboard from a view controller

I am developing an application that loads a web page (using UIWebView) using Storyboard (I do know nothing about previous xib neither). I have already created a view controller for that UIWebView and everything works fine. The thing is: since previous versions of iOS don't allow to upload files, I need to make a new view (scene I thought it is called) that allows the user to pick and post a picture. I am able to develop both views separately and they work as expected but now I need to connect them based on event triggered when user wants to post a picture to the server. Using
