导入修饰函数

Question

I have a number of functions in separate files with pynodered decorators, which pynodered will import one by one.

so I call from the command line.

pynodered file1.py file2.py 

these file1.py etc. look like this

from pynodered import node_red

@node_red(name="Unblock user",
              title="Unblock User in AD",
    def unblock_user(node, msg):

However I would like to have one big file to import them all (basically because it is easier to manage which nodes to load)

import file1
import file2

and then start pynodered like

pynodered bigfile.py

But apparently this doesn't work as it cannot register the functions Exception: Zero function or class to register to Node-RED has been found. Check your python files

Any ideas how to fix this?

Answer 1

hmm. that is interesting. i was tryign to break up my one single bigfile to do opposite of you. my current big file has the decorators for around 5 or 6 functions intwo different categories. they all show up fine.

The following description from pynodered will be useful for you

"""
def node_red(name=None, title=None, category="default", description=None,
             join=None, baseclass=RNBaseNode, properties=None, icon=None, color=None, outputs=1, output_labels=None):
    decorator to make a python function available in node-red. The function must take two arguments, node and msg.
    msg is a dictionary with all the pairs of keys and value sent by node-red. Most interesting keys are 'payload', 
    'topic' and 'msgid_'.
    The node argument is an instance of the underlying class created by this decorator. It can be useful when you 
    have a defined a common subclass
    of RNBaseNode that provided specific features for your application (usually database connection and similar).
