How can I validate if a view exist in the project folder with perspective

Ignition

Is ther a way to valide that a view exist?

Actually I use a script with hardcoded path, but I search a way to do that more efficially with binding path.

My script;
path = “C:/Program Files/Inductive Automation/Ignition/data/projects/AMT/com.inductiveautomation.perspective/views/1-UDTS\AS0153_TRIM_PRESS/SETUP/Elems”

value = system.file.fileExists(path + “/Extras/ejector_closed_position”)
return value

I have a button that I want to root to a specific view if the view exit.

Anyone have better solution for me?

You should be putting all of your code within preformatted text characters ``

This = some_code
If you_add:
       Tabs = 'they remain intact'

I don’t understand your explanation. How can I validate if a view exist in a specific folder of my project?

He’s saying you should post your code by putting it between

```

my code here

```
so that it gets formatted and we can read it better

From your post its hard to tell exactly what your script is, how it’s being called, if its inside a function, etc. However, I think it sounds like you just want a function that checks if a file exists? system.file.fileExists already does that. But if you ar einclined to make your own function, you can do

def fileExists(filePath):
    """
    Checks if a file exists.
    Args:
        filePath: str, file path to check
    Returns:
        boolean, true if file exists, false otherwise
    """
    import system.file
    return system.file.fileExists(filePath)

I know that and I want to build my own function, but I don’t want to have to specified the local path of my perspective project manually. I search a way to be able to get the direct path to my perspective project folder.

def transform(self, value, quality, timestamp):
	"""
	self.view.custom_view_path = C:/Program Files/Inductive Automation/Ignition/data/projects/AMT/com.inductiveautomation.perspective/views/

    I search a way to get that path withaout having to declared it manually.  How to get perspective view path of my project?
