How to - Extending nopCommerce v2.0

Thank you for your feedback "New York". I'll make the modifications you recommend. I use Resharper during development which makes adding references a lot easier and it is easy to forget to document them. I wrote that article as I was writing the plugin to ensure it was working correctly, but a combination of me getting lazy and changes to how I wanted the code structured introduced differences between the blog and the plugin code. Thanks for your feedback.

@skyler.severns

I was wondering if you can help us developing a payment integration plugin for EBS? Awaiting your response.

It is not ready yet. Does anybody know about another blog/thread with such tutorial?

Thank you in advance,
Serge.

Hi skyler

Are you still making a tutorial on how to add a new entity?

thanks

Yup. I'll make one this weekend.

OK, I've added a new post explaining how to create a new plugin that has a new database entity. I hope it helps and let me know if I need to change something.

@Jariwalakrunal,

I'll look into it, but I don't think I'll have time. I'm trying help as much as I can in my spare time and that would be too large of a project for "spare time". I would be happy to help answer questions for anyone who takes the project on.


Unrelated to Jariwalakrunal's post I've added a new article. It is a "cheat sheet" for the different upgrade resistant ways to extend nopCommerce functionality.

Would you be able to provide a basic outline of the steps required to create an Admin Plugin?

Hi All

I added a plugin with route as follows;

routes.MapRoute("Nop.Plugin.Orders.LineItems", "Plugins/LineItems/List", // The route name, and the actual route.
                                                            new { controller = "LineItems", action = "List" }, // Route defaults
                                                            new[] { "Nop.Plugin.Orders.LineItems.Controllers" }); // The namespace where controllers are stored


And now i want to access that through Admin section.. say from List.cshtml in Orders.
So i added <a title="Order Line Item" href="@Url.RouteUrl("Nop.Plugin.Orders.LineItems")">Order Line Item</a> in that view.

When I click I m gettin resource not found error;

"Server Error in '/' Application.
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable.  Please review the following URL and make sure that it is spelled correctly.

Requested URL: /Plugins/LineItems/List"

Please please help me on this..

I was able to resolve that issue.

When I add this plugin to Admin.. I am getting some errors;
