Course evaluation for beginner frappe/python developer?

[Alexander_Themohan]

Hello, I have very basic knowledge of programming and web development. Last web application I made was 3 years ago using Ruby on rails for learning purposes. I have some experience with Erpnext, I can create custom doctypes and customize existing doctypes. But I want to develop some business applications I have in mind. I watched through the frappe webinars and I understood a good portion of what they showed, but I dont know much about python on postgresql, So I looked around and found this course on udemy for Python and Postgresql.

The Complete Python & PostgreSQL Developer Course

The Complete Python & PostgreSQL Developer Course

I am planning on buying it, but it would be great if somebody could glance over the curriculum for this course and tell me if it will be enough to get me to be able to at-least start developing something on frappe after learning this.

Or maybe recommend some beginner friendly courses that you prefer.

Thank you

Really depends on what kind of custom applications you want to build. If you are more or less familiar with ERPNext, the best way to learn is, when you look to implement a use case, try to look at how a specific system has been implemented in ERPNext.

If your custom application needs more JS, then you might want to study that side.

Edit: That reminds me that it might a good idea to start a documentation with the title “Design Patterns in Frappe”

I haven’t looked at the curriculum but basics of Python and JS are important. Esp. Data structures like dictionaries, lists etc. in Python are important.

Even more important is to read the code already written in the Frappe/ERPNext apps. Use the doctype or report, and try to understand why the feature works like that. Reading queries from the forum and trying to help out other users will also help you learn better.

Also, since you will be interacting with the Database a lot, so learn MySQL queries (ERPNext also is probably coming up with Postgresql support)

You can buy it, use it and write more code and understand how code works - use it as a means to become better. There will always be more to learn. Best of luck !

Came across this post.
This has been my (and many others I believe) long search. I see many posts for first time developer/customizer of Frappe/ERPNext is questioning the architecture:

• what are the domains, modules, features.
• how they relates to each others (e.g. some Frappe functions are overridden by ERPNext).
• how the hooks and api will override the default method.
• how to override defaults file (py, js, html) by using custom app.
• how (and at what steps) the defaults values and documents are created.
• and other questions…

I’m not a developer myself. My first and most problems are not syntax related (the built-in codes are comprehensive, complete, sometimes having more than one options, quite simple, and mostly easy to duplicate), but on finding out what and where to override.

I hope I’m not making things complicated
