How to work with NopCommerce MVC as a team - asp.net-mvc

We are currently looking at the newest version (2.60) of NopCommerce in MVC and we will be integrating it pretty soon…We’ve downloaded the Source Code and paid the 20$ for the User Guide documentation. The documentation is great! I mean…it is great in the sense that it explains how to deploy, install and how to work around the UI Frontend and Backend. This is great for an overall overview but what it lacks is the understanding of how to work with NopCommerce as a team. What are/is the best practices etc...
As an example (or parallel), if you decide to work with Dotnetnuke as a team, you usually work in the following fashion:
Each developer downloads/installs Dotnetnuke locally on their
machine.
You also download/install Dotnetnuke on a dedicated server (let’s say
dev-server).
As a developer, you work and create modules which you test locally
within your Dotnetnuke installation.
Once it is done, you package your module (and any SQL scripts that
comes with your module) into a zip file.
Once the package is ready, you upload/install that package on the
dedicated server (dev-server).
This approach works great for Dotnetnuke and more importantly if you have a team of developers creating modules.
My question is how does a team work with NopCommerce MVC?
I’m assuming it is a bad idea to directly work within the source code in case your team decides to modify core elements/source which will make any upgrade to newer versions impossible (or break changes).
I’m not sure if my parallel to Dotnetnuke is a correct one…but would anyone have any idea (or help me clarify) how does a team work with NopCommerce MVC.
In addition, should the team only rely on creating plugins for NopCommerce and stay away from modifying the core or should this be irrelevant?
What about adding new objects in SQL (or modifying existing ones) should we prefix our objects in case an eventual NopCommerce MVC upgrade creates similar objects and/or overwrites them?
Thank you for helping me shed some light on this.
Sincerely
Vince

Plugins in NopCommerce are almost like modules in DNN. Depending on what you need to do, it sometimes is necessary to modify the core code.
What I've been doing for the Services is create a new class and inherit from the existing service, then override the function you want to change. Create a new DependencyRegistrar class and set your new service classes as the implementation for that particular interface. Also make sure the Order property is 1 so that your DR class is loaded after the stock one. Since you're inheriting from the core class, any functions you didn't override will be handled by the parent class. If I need to add a new function, I'm just modifying the interface, putting a stub in the stock class, and implementing it in my own.
Views in the Nop.Web project can be overridden by Themes. The Admin stuff and the Web Controllers get trickier. I'm just modifying those files directly.
The Core and Data classes can be done using partial classes to add your new fields.
In any case you will still need to merge changes with your solution when an update is released. My opinion is that you are better off writing clean, readable code now and bite the merge bullet when it comes.
I don't really worry about SQL scripts right now because I'm a single developer but maybe you add a folder for ALTER scripts and name them after the day they were created. Then each dev knows which scripts they need to run when they get latest.

How do I convert a specific controller to a package to include in other projects?

VS2013, MVC5, VB
I am nearing the completion of a small project to manage the roles tables in a standard MVC5 application. The code is pretty much encapsulated. What are my options for using this 'package' in other projects?
Can I compile it into something? I know this type of action is possible, I'm just not familiar with the options available to me or the steps to do this. Links to sites that have tutorials are fine. Is creating a Nu Get package the only way to go, or is that even in the ballpark of what I'm asking. I say Nu Get, but I don't mean for public consumption, only for my consumption.
Will the finished 'whatever' include it's controller class, view models and views? Will I be able to easily manage updates? etc.
Creating a Nuget package is one way. I have created a local repository of common utilities for this purpose. But I usually use it just for DLLs. I use Nuget Package Explorer for its ease of use since its just me using the packages most of the time. Not sure its possible to place the files in specific directories.
Files in the content folder are copied to the root of your application when the package is installed. - Nuget
The alternative is to create an item template. I used to use this method for class files I want in my code but I can't see why you couldn't do it for the rest. Works well and isn't too hard to set up. There are dozens if not 100s of tutorials on the subject. Here is one on code project.

How to reuse a mvc app

I've created a web app (mvc4) that I'd like to reuse in multiple projects. The site is an admin panel, but it may be extended and slightly modified in each project. I want to avoid copying the project over, because I'd like to be able to update each project to the latest version at the lowest possible cost.
So far I have tried 2 approaches:
a script that 'clones' the project by copying all the necessary things as well as altering others (guids in assemblies, namespaces and things like that) - this works fine for extensibility and modification, but that's just a copy so pushing 'updates' is a mess (I did it manually) and it does not scale.
portable areas from mvc contrib project - this seemed like a good idea at first, but it turns out that it's nice for simple scenarios, but fails at more advanced use cases. It doesn't support localization (from resources embedded in the portable area), bundling and min requires a lot of hacks (mvc contrib is still on mvc 3), it's not possible (out of the box) to reuse shared views or Display/Editor templates from the portable area and it looks like if I'd go further that way, some new things would come up
Currently I'm thinking about 'just' branching each project from the core one. This would of course require the same changes (or at least a big subset of them) that were done in the script I mentioned earlier, and I'm afraid that if I try to pull updates from the core project the number of conflicts will render the whole approach unusable.
Does anyone have an idea on how I could tackle this problem?
I'd suggest to create a NuGet package of the mvc app and reuse it. So versioning and applying updates would be much easier. However it takes a bit work to make your code completely isolated from the codes you want to add in the new project.

Organizing, Storing, and Keeping Track of code for reuse

Many moons ago I started storing my music as MP3’s. I downloaded like mad and just dumped them all into a folder. After collecting thousands of songs I had a big mess. After two years of organizing all music in my free time I have made it to “D” section of my library. I am starting to write code on a daily basis and I would like to keep a lot of what I do for reuse and future reference. I use Visual Studio a lot, and Eclipse sometimes, but I also do web development. Right now I am just have a folder on an external drive called Projects and inside that folder I have code I want to save broken down by its respective IDE and then the language it was developed in. This is working ok right now, but I fear after a few years it might get hard to navigate, and I don’t want another mess like my music library. What are some good ways to keep track of code and programming projects while also promoting easy navigation and future reuse?
I use a subversion repository for purpose of saving code for the future. In my repository I have the following folder structure:
\
|- Project1\
|- - Trunk\
|- - Branches\
|- - Tags\
|- Project2\
....
This is working for me and I have big and small projects that I coded on since high school in this repository. If I for instance want to port a project that I coded on Linux to Windows I create a branch that I for example call Win32-port. And when I have a 1.0 release of a project I create a tag named 1.0.
Using this method you can also set up back-up scripts and save a backup to another location. (I use a cron job and some python scripts to achieve this, but it all depends on what system the server uses.)
A book about subversion are freely available here: Link
For Mac OS X, there's the beautiful Snippets:
(source: snippetsapp.com)
Also, the new Xcode 4 will have native support for custom code snippets.
It won't really solve your organising problem, but you'll be more productive anyway by using snippet be it inside Eclipse or inside Visual Studio.
Here's a short tutorial for snippet in Eclipse : http://www.dansshorts.com/post/creating-snippets-in-eclipse
And here the explanation to create them and link them to a keyword in Visual Studio 2010 : http://www.visualstudiotutor.com/2010/02/create-snippet-visual-studio-2010/
This would take a bit more infrastructure to set up and is more for multiple people working together, but the best approach is to start thinking of Software as a Service.
For commonly used functions, wrap them as a web service with good documentation. For instance, if you have a phone validator that seems to be constantly used across projects, it would become part of your validator service.
With few exceptions, most shops don't seem to organize/share code effectively with static document type code libraries.
This would also force you to refactor the code snippets into reusable methods instead of just random code that is copied/pasted in. It also gives you a clean seperation between the public interface and private implementation.

Visual Studio: What approach do you use to 'template' plumbing for similar projects?

When building ASP.NET projects there is a certain amount of boilerplate, or plumbing that needs to be done, which is often identical across projects. This is especially the case with MVC and ALT.NET approaches. [I'm thinking of things such as: IoC, ORM, Solution structure (projects), Session Management, User Management, I18n etc.]
I would like to know what approach you find best for 'reusing' this plumbing across projects?
Have a 'master solution' which you duplicate and rename somehow? (I'm using a this to a degree at the moment, but it's fairly messy. Would be interested how people do this 'better')
Mainly rely on Shared Library projects? (I find this appropriate for some things, but too restrictive for things that have to be customised)
Code generation tools, such as T4? (Similar to the approach used by SharpArchitecture - have not tried this myself)
Something else?
Visual Studio supports Custom Templates.
I definitely (mostly!) go for T4 templates in conjunction with a modified version of SubSonic 3. I kind of use the database to model my domain and then use the T4 templates to generate the model and associated controllers and views. It takes about 50-60% of the effort out and keeps a consistency in place.
I then work on overrides (partials) of the classes along with filters and extension methods to 'make the app'. Now that I'm familiar with the environment and what I'm doing, I can have a basic model with good plumbing in place in a very short space of time. More importantly, because I create a set of partial class files, I can regenerate all I want without losing any of my 'custom' coding.
It works for me anyway :)
You could do it the bearded, t-shirted, agile style and create a nice template and put it in sourcecontrol. So when you need a new project, you just checkout the template?
For insanely fast MVC site setup, I use modified T4 templates (created with T4 Editor) and with ALOT of help from Oleg Sych's blogs for page generation (for your typical add/edit/index pages) combined with an awesome implementation of an automated create-update-delete called MVCCrud (if LINQ-to-SQL is your preferred data access method)
Using modified T4 templates and MVCCrud you can create fully functional entities (Create/Edit/List/Delete) with error handling and intuitive error messages in about 4 minutes for each.
I create a new project using the new project wizard so that I get unique project GUIDs assigned. Then I would use "Add Existing Item" to copy items from similar projects if it made sense to do so.
I sometimes use a file diff tool to copy references from one project to another, otherwise I just add the references by hand. A file diff tool can also be used to include similar source files, but the underlying files have to be copied anyway, so I prefer "Add Existing Item".
I've used T4 to generate solution and project files, but that definitely seems like an edge case and not something that would normally be necessary. In that case, I'd probably wrap the T4 in a PowerShell like script to create and populate the rest of the directory structure.
I use "shared libraries" pretty aggressively in general, but not specifically due to this scenario.
In general, I don't find myself reusing plumbing between projects much. It's probably more often that I hack away in one "prototype" project, then abandon it, and rebuild the project from scratch following the above approach and only bring over the "non-hacky" code.
I'm creating a MVC2 application template at http://erictopia.com. It will contain all the basic items I think should be in a MVC project. These include BDD specifications, an ORM (NHibernate and possibly Lightspeed), T4 templates, custom providers, ELMAH support, CSS/Javascript minifier, etc.

How does one make a Grails application designer friendly without the need to re-deploy after a change to the view?

It has been a long while since I have really worked with J2EE so please excuse my ignorance. My recent engagement in a Grails project has peaked my interest in Java once more and especially in Grails as it makes building web applications on the Java platform fun again. That being said, I would like an expert to comment on the following requirement that I have for an application built using Grails:
The Design Team (web designers) require access to the GSP pages and edit the view files (layouts, templates, etc.) without bothering the development team (software developers). This scenario can take place both during construction and after deployment into production.
The communication level between the Designers, Developers, and Business Users are not an issue here. However, about 40% of the time, the Business Units involved request changes to the front-end that have no impact on the Developers time but require the time of a Design Team member. Currently, the deployment workflow follows the Grails application through the deployment of a War file to a Tomcat server. I imagine there is a simpler way to allow the Design team to make UI changes without going through the build and deploy lifecycle.
Several of the Design Team members have had exposure to PHP in the past and at times miss the ability to just overwrite a template file to make a UI piece more functional or improve a layout template. I hope there is a similar way to accommodate such simplicity within Grails. I have been told that exploding the War file might be an option but that still requires the reload of the Tomcat hosted application.
If you believe that I looking at the desired solution the wrong way, please do chime in as I am more interested in a workable compromise for all the team members involved. Thank you.
You need to specify the following settings in Config.groovy:
grails.gsp.enable.reload=true
grails.gsp.view.dir="/path/to/gsp/views"
The 'grails.gsp.view.dir' is typically the path to your checked out SVN repo. You can then just 'svn up' everytime you want to update the views.
There is one caveat: When a GSP view is compiled it uses up permgen. Eventually you will run out and need to restart the server.
You could run a server with a version of the application via run-app in development mode. The designers can then make changes to the views and they will reload. They would need to be able to acccess the source code on the server via a share of some kind. As a plus, if you checked out the source the designers could then commit their changes from the server.
The downside is that if the reloading fails or you run out of memory (has been known to happen with lots of reloading) either a developer would need to stop and start the app or you could provide the designers with a script to run to bounce it.
You'd obviously take a performance hit by running in development mode and via run-app but it might a ok trade off in your case.
cheers

This may not be the direct answer for this question but since you seem to pay attention to designers' role in a project, you may also check my designer friendly GSP implementation which enables designers to view GSP pages even with custom tags thanks to the "tag declaration via attributes" feature.
