API parameter, cannot use list parameter

1

Hi,

I’ve tried to pass list parameter into function using rest API, but list parameter passing in will got convert into first item of the list.

Code example:

@frappe.whitelist()
def read_list_param(list_param):
	print(type(list_param))
	print(list_param)

Input:

{
	"list_param": [1,2,3]
}

Output of read_list_param function

<class 'int'>
1

This is because there are conversion happening when received parameter.

Added by this commit. (Year 2014)

I don’t know why do we need this since list is a valid JSON.
I’ve tried and remove this conversion and the apps works just fine.
The question is do we still need this conversion ?

My use case is I want to pass list parameter into rest API.

Update,

Changing

try:
	frappe.local.form_dict = frappe._dict({ k:v[0] if isinstance(v, (list, tuple)) else v \
		for k, v in iteritems(args) })
except IndexError:
	frappe.local.form_dict = frappe._dict(args)

to

frappe.local.form_dict = frappe._dict(args)

Will break the app (on production setup, it doesn’t on development setup don’t know why)

For now my workaround is wrapping list into dict

Input

{
	"list_param": {
		"list": [1,2,3]
	}
}

Process

list_param = list_param.get('list')

Then every thing should work as intended.
