N2 Documentation

N2 is the next evolution of the Nuido ecosystem, designed to bring a unified and streamlined approach to visual automation in Odoo. Where the original Nuido library focused on node-based user interfaces and Nuido Flow extended those capabilities into visual automation, N2 consolidates these concepts into a single, cohesive framework.

Unlike its predecessors—which separated functionality into distinct base modules—N2 is built on two core components:

  • N2 — the backend foundation, providing Python logic, XML views, and server-side integration.
  • N2 UI — the frontend layer, delivering the JavaScript framework, client views, and interaction model.

On top of this foundation, N2 includes additional modules that correspond to the functionality previously offered by Nuido Flow. For example, the N2 Trigger module serves the same purpose as the former Nuido Trigger, while leveraging N2’s modernized architecture and unified design.

Together, these components make N2 a flexible, robust platform for building visual automation experiences within Odoo.

Document Conventions

This documentation uses visual badges to indicate how a node’s parameters are interpreted and processed at runtime. Each parameter may have one or more of the following badges applied to it.

Parameter Badges

  • Raw: The parameter value is passed through exactly as written, without any evaluation, parsing, or transformation.

  • Eval: The parameter value is fully evaluated with default context and active record info as an expression before it is used. This allows dynamic computation and access to runtime context.

  • Patched: The parameter is interpreted as a model name. One or more methods of the referenced model are patched or overridden before use, altering its behavior at runtime.

  • Liteval: The parameter is treated as a lightweight expression and evaluated before use. Compared to Eval, this evaluation is more restricted and is intended for simple expressions.

  • Tmpl: The parameter is treated as a template. It is first parsed and then evaluated, allowing interpolation of variables, expressions, or other dynamic content before being used.

  • Inherited: The parameter is defined on the parent node and inherited by the node.

  • Dict: The parameter is treated as a raw dictionary value and is deserialized using json into a Python dict before use.

Documentation Status

This documentation is an ongoing process and may be updated regularly as new features are added, existing nodes are enhanced, or workflows are improved. While the content provided here covers the basics and common use cases, some advanced features, edge cases, or specialized nodes may not yet be fully documented.

We encourage readers to:

  • Follow updates and revisions to the documentation for the latest information.
  • Explore node-specific documentation for detailed parameter descriptions and examples.
  • Experiment within N2 to gain hands-on understanding, since some behaviors may only be fully clear through practical use.
  • Provide feedback or suggestions:
