How to send a boolean to python-eve? - rest

Question

I'm trying to update a boolean value using python eve, but I always receive the same error,
_issues: {deleted:must be of boolean type}
deleted: "must be of boolean type"
_status: "ERR"
I've tried sending the field as true (setting javascript type) 'True' and 'true' (as text) and 1, but the error is always the same.

Any idea?

Answer 1

If you change your schema to coerce deleted value to bool, you can send int or str values and have it converted to bool on insert/update
First, create a function to convert whatever comes, to bool:
to_bool = lambda v: v if type(v) is bool else str(v).lower() in ['true', '1']
Then, change the deleted in the schema to use the function to coerce values, like this:
'deleted':{
'type':'boolean',
'coerce': to_bool,
'default':False
}
With this, you can per example send deleted with values such as '0', 0, 'false' or 'False' yelding to boolean false, or '1', 1, 'true' or 'True' resulting in true

Answer 2

This happens only when you send the request in the content type of form-data or application/x-www-form-urlencoded. In case of AJAX requests, sending boolean value works.
var payload = {
"deleted": false
};
var xhr = $.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
data: JSON.stringify(payload),
dataType: "json",
url: "some url"
})

Answer 3

Your payload should be a dict like:
payload = {"somebool": False}
then you convert it to a json string:
payload_json = json.dumps(payload)
which results in a lowercased bool value in a string:
'{"f5only": false}'
then you shoulc be able to post or patch it:
requests.post("{0}/endpoint/".format(api_server), headers=headers, data=payload_json)
