I find that every solution needs some sort of bespoke function . For example, I recently implemented a SendGrid as a way of handling emails for drip campaigns. I wrote a SendGrid class that inherited from a DripInterface.</p> <p>However, what if SendGrid doesn&#39;t work out, and we want to switch to Mailgun for the drip campaigns? Well for the most part, we&#39;ll write a concrete MailGun implementation and we won&#39;t need to change anywhere other than where the dependency injection is handled.</p> <p>There are a lot of functions that cross over perfectly, I can handle contact lists, (GET/PUT/DELETE), categories, sub categories etc, and I can create interface entries for these all. But <strong>how do you handle it when there&#39;s something specific to the Concrete class that I need to use</strong>, that doesn&#39;t work in the same way as any future concrete classes?</p> <p>At this point I always end up writing code that kinda suits SendGrid, and when we have to switch out to Mailgun I&#39;ll have to find every file that injects the DripInterface, and swap out the method calls or add a few more to specifically handle this different class.</p> <p>What&#39;s a clean solution to this?

The controller feels like it violates the rules of encapsulation. It has complete access to the entire front end GUI including access to frames, buttons, textfields, etc. That is not good. Buttons, textfields, frames, stages, images, etc are all part of the view and ONLY the view should modify said variables. Also it&#39;s very likely that inside the view, you can create objects of the model. That just doesn&#39;t make sense. Classes declared in the model should NOT exist in the view. They are completely seperate, which should mean that the identifiers for classes in the model should be unknown when I attempt to reference them in the view. This is <em>somewhat</em> possible with packages in a language like Java but overall I never see people do this.</p> <p>Same problems with the model. I might have a model of a <code>Racecar</code>. My controller might have a section for <code>start car</code> which in turn calls <code>rc.ignition()</code>. But there&#39;s <strong>nothing</strong> that stops me from doing <code>rc.setWheels(0)</code>. Because my controller has access to the entire backend since its an instance variable, it has complete control over everything it can do. That doesn&#39;t make sense.</p> <p>I&#39;ve taken two Object Oriented Design classes and in the advanced one, the teacher told me &quot;Yes, this is true, but that is <strong>your design</strong>. It is okay for things to be this way, as long as its part of your intended design&quot;. I&#39;ve really never liked that answer because it feels like it doesn&#39;t address the violation of the rules of MVC (model and view being completely seperate in every way).</p> <p>I had an idea on how to solve this, but wasn&#39;t sure exactly if it was a good idea.</p> <h1>Model</h1> <pre><code>class Racecar public int currentSpeed; public int wheels; public void speedUp() { ... } public void dismantleCar() { ... } </code></pre> <p>.</p> <pre><code>// read-only version of the speed indicator interface RacecarSpeedIndicator public int getCurrentSpeed(); </code></pre> <p>.</p> <pre><code>// next level of the hierarchy // gives way more permissions than the above one interface RacecarAccelerator extends RacecarSpeedIndicator public void speedUp(); </code></pre> <p>Then I have <code>Racecar</code> <code>extend</code> <code>RacecarSpeedIndicator</code> and <code>RacecarAccelerator</code>.</p> <p>When my front end needs to accelerate the car, it would look like this:</p> <pre><code>class Controller1 RacecarAccelerator rc; public Controller1(RacecarAccelerator rc) this.rc = rc; // here, Controller1 CAN ONLY speed up the car // and read the current speed. It cannot // possibly cause any harm to the race car </code></pre> <p>It&#39;s kind of like having access cards at a building. With a RED access card, you can access a certain number of areas. With a BLUE access card, you can access all RED zones and all BLUE zones, etc. You only give a section of code the BARE MINIMUM it needs to perform its funciton. But is this idea convoluted? Does it exist as a pattern? How does it contrast with MVC?</p> </div><!-- SC_ON --> &#32; submitted by &#32; <a href="https://www.reddit.com/user/Hatefiend"> /u/Hatefiend </a> <br/> <span><a href="https://www.reddit.com/r/DesignPatterns/comments/fdsfz8/im_not_satisfied_with_mvc_feels_like_it_breaks/">[link]</a></span> &#32; <span><a href="https://www.reddit.com/r/DesignPatterns/comments/fdsfz8/im_not_satisfied_with_mvc_feels_like_it_breaks/">[comments]</a></span></content><id>t3_fdsfz8</id><link href="https://www.reddit.com/r/DesignPatterns/comments/fdsfz8/im_not_satisfied_with_mvc_feels_like_it_breaks/" /><updated>2020-03-05T08:44:40+00:00</updated><published>2020-03-05T08:44:40+00:00</published><title>I'm not satisfied with MVC -- Feels like it breaks encapsulation</title></entry><entry><author><name>/u/Rosechan1</name><uri>https://www.reddit.com/user/Rosechan1</uri></author><category term="DesignPatterns" label="r/DesignPatterns"/><content type="html"><!-- SC_OFF --><div class="md"><p>Learning dependency injection and wondering if this code implements it.
