How do you post form data using pytest? - pytest

Question

I'm trying to write a unit test that posts form data. The actual line in question is:
def test_create_request():
with app.test_client() as test_client:
app_url = '/requests/'
with app.app_context():
new_request = get_new_request()
form_data = json.dumps(new_request, default=str)
print('FORM DATA: ', form_data)
resp = test_client.post(app_url, data=form_data, headers={'Content-Type': 'application/json'})
assert resp.status_code == 200
s = json.loads(resp.data)
assert s['success'] == True
Where new_request is a dict representation of an object. The print statement yields (I've formatted it a bit):
FORM DATA: {
"request_id": "6",
"state_id": 1,
"orig_project_id": "1",
"orig_project_code": "QQQ",
"orig_allocated_funding": "123.45",
"orig_ytd_spend": "123.45",
"orig_ytd_commit": "123.45",
"orig_ytd_ocnr": "123.45",
"new_project_id": 2,
"new_funding_amount": 123.45,
"new_ytd_spend": 123.45,
"new_ytd_commit": 123.45,
"new_ytd_ocnr": 123.45,
"plan": "this is the plan",
"reason": "this is the reason",
"sm_director": "sm.dir#example.com",
"submitted_by": "xfgbn#vexample.com",
"created_on": "2021-09-14 16:32:55",
"meets_approval_guidelines": null
}
In the flask form, most fields are required. When I try to post the data, the form.validate_on_submit() function in the view's route returns False, and the 2nd assert fails. WTForms claims that none of the required orig_allocated_funding, orig_ytd_spend, orig_ytd_commit, orig_ytd_ocnr, new_project_id, new_funding_amount, new_ytd_spend, new_ytd_commit, new_ytd_ocnr, reason, plan, sm_director, or submitted_by fields are supplied.
I've read several tutorials, and I can't see what I'm doing wrong. Can anyone help?

What I was able to make work was scraping form_data altogether:
def test_create_request():
with app.test_client() as test_client:
app_url = '/requests/'
with app.app_context():
new_request = get_new_request()
resp = test_client.post(app_url, data=new_request)
assert resp.status_code == 200
s = json.loads(resp.data)
print(s['html'])
assert s['success'] == True
