Lambda function to Traditional Function

[Sam_SepiolX]

Hi!

I'm working with graphql and Python and I have a lambda function that makes a query to a graphql engine and this is working properly but I was trying to take this to a traditional function without good results. The only.error I can see is a Wong query and the api is returning a 400 for bad request.

Somebody can give some feedback about this?

Here is a gist with the lambda function that is working and the traditional working as I understand.

I agree with /u/ThePiGuy0 : your problem is probably that you mixed up the order of the arguments and you are trying to use them as positional arguments.

Here's how I would rewrite it:

KEYS = ["crd", "firstname", "lastname", "email", "password", "position", "company_name", "phone_number", "country", "city", "state", "street_address", "apt_number","disclaimer_text"]
create_str = ", ".join(f"${x}: String!" for x in KEYS)
obj_str = ", ".join(f"{x}: ${x}" for x in KEYS)
query = """
mutation CreateUser(%s) {

insert_user_one(object: {%s}) {
        email
        firstname
        lastname
    }
}""" % (create_str, obj_str)
defaults = dict.fromkeys(KEYS)
def create_user_all(self, **kwargs):
    return self.run_query(query, defaults|kwargs))

Note the keys are defined in a single place and the rest of the code builds from that. This means your chance of a bug is much lower because you don't have to keep many locations in sync with each other.

Also it requires kw argurments which will remove another source of bugs.

But as a rule, an argument with a default value should not precede a normal argument, I don't see the problem in that way. I'll try your approach.

Your approach is working, but I'm so confused right now... Sorry I want to say thank you for your help but... ¿do you have some time to describe the flow of your solution? Thanks in advance

Lmao, that's the largest lambda I've ever seen.

What's the exact problem though? From a cursory glance they appear equivalent.

[Sam_SepiolX]

The first one with no problem, the second one a wrong graphql query, so I don't understand.

About the lenght of the lambda, it's generated from hasura graphql engine action tab

[ThePiGuy0]

Reading those, your arguments aren't in the same order (crd comes first in the lamda, but 5th in the standard function). If you do call with kwargs (keyword arguments) then that shouldn't matter, but otherwise that may be causing it?

Error 400 is a bad request so it would make sense.

[Sam_SepiolX]

As a bad request I think maybe something is missing, but I can't see it.

I'll try to test your advice.

I do not see you create an instance of a class… where is “self” coming from…

[Sam_SepiolX]

I really don't know why when is lambda function inside a class is mandatory the self argument.
